The chill of autumn is upon us, and with it comes the awkward sport of trying to work touch-sensitive phones and gadgets with gloved fingers. One can try toughing it out with fingerless gloves, or we’ve seen some costly solutions in the forms of specialized gloves and capacitive-compatible styluses, but sometimes simple is best:
all it takes is a few stitches of conductive thread in the fingertips
.
Conductive thread
is available from various sources;
SparkFun Electronics
comes naturally to mind, but most vendors carrying the
LilyPad Arduino
will stock a suitable thread as well. Don’t fret if you’ve never
sewn
before — just a few simple loops are required, and it doesn’t need to be especially tidy. In principle this should work for trackpads and
capacitive mice
as well, if you use those in the field. For
multitouch
devices, add a separate conductive bit to each fingertip.

Recover Borked HDD After Xbox 360 Ban

[Incudie] tipped us off about
a method to fix a borked HDD in your Xbox 360
. Many of the
one million consoles banned
earlier in the month also had the hard disks scrambled making off-line gaming impossible as well. It turns out that this is caused by having a ban flag in the NAND chip on the motherboard. It has been discovered that because of
wear levelling
, the NAND will have two copies of the “secdata.bin” file which stores the ban flag. Please note, this will NOT allow the console to use Xbox Live, it just re-enables the HDD.
The quick and dirty of the fix is as follows: First the
NAND is dumped
from your Xbox 360 to a computer. After verifying the file, it can be opened in a HEX editor and the two copies of “secdata.bin” located. Once identified by date, the older version is injected on top of the newer to overwrite the ban flag.
Looks like this is not for the faint of heart, but if you got banned for modding in the first place this should be easy to pull off.
Update
: Looks like xbox-scene now has a
collection of apps to help you
with this process. [Thanks CollinstheClown]

Mine had 27 on a 16MB NAND, someone else with a 256MB NAND only had 13 (probably because it was newer… less updates).The ban doesn’t cripple the HDD completely, you can still use it besides HDD game installs. However, anything saved after the ban flag is set in the secdata.bin will not be signed by the console and will show corrupted in any other console, regardless of whether you are using the HDD or a memory unit. The NAND fix removes the ban flag, so profiles are no longer corrupt across consoles and you can once again install to HDD.Odds are it fixes the media center abilities being disabled too, but I’ve not tested this since the 360 is a piece of crap for a media extender.",

[Alton Brown], the consummate kitchen hacker, has been kind enough to share the safe method of deep frying turkey. This includes how to measure for liquid displacement, and
how to build a derrick
(PDF) to lower the turkey into the pot from a safe distance.

You can safely lower a turkey into the pot at 375 degrees and regulate to 350 without getting sprayed with hot oil.I retired my first turkey pot after 100 turkeys and an well on my way to retiring pot #2.Never burned once. But, I pay attention, and ensure that the oil NEVER GOES ABOVE 375.375 degrees, you say? Yes indeed. The oil temp drops rapidly when you lower the bird, and it takes a long time for it to come back to 350, which is the ultimate deep frying temp.Remember what the 3 enemies of your oil are : Water, Salt, and excessive temperature.",

If you watched the video before
reading the article
(like we did) and started shaking in your boots at a voice controlled lock system, prepare to be disappointed. His spoken commands are actually to his son to press the appropriate keys on a keypad off screen, the lock is not actually voice controlled.
But still, [Michael Krumpus’] door lock is pretty astounding. By using a torn apart CD drive he easily attains a nice fast and smooth linear motion to bolt and unbolt his door. It wont open his door like some locks
we’ve seen
, but it will probably be added sometime in the future…right alongside voice commands.

Blac & Decker, who makes the Weiser Power Bolt, had a lot of issues with doors that weren’t hung exactly right. As a result, the bolt wouldn’t engage strike pocket.Ultimately, they fixed a huge majority of the problems by going to a bullet-nosed bolt. As the bolt engages, the door moves into position.Being a battery operated lock, there’s a tradeoff between torque and battery life. All the torque int he world will do you no good if the batteries only last 2 months, and having batteries last two years, but with a bolt stopped by ANY binding is worthless.This is a cute “hack”, but it’s unfortunately not terribly practical. In a situation where you have a swinging door, an electric strike is your best bet. Requires more installation effort that just replacing the bolt, but fitting an electric strike into a strike pocket is a lot easier than fitting a CDROM mechanism into the wall or the door.",

My 5-year-old son was operating the lock from the keypad when I filmed its operation. I SHOULD have listened to my 9-year-old son when he commented “this video makes it seem like the lock is controlled by your voice”. !!! Nonetheless, the lock is operated by a keypad. The user must input the proper code to lock/unlock the mechanism.The bolt looks flimsy but it’s pretty sturdy. By drilling big holes in the door and jamb, I had plenty of tolerance to deal with misalignment. I WAS worried about alignment, but it worked out well.

How would you like to have a 3-axis accelerometer, pressure sensor, temperature sensor, RF wireless, and an LCD screen in a development package? What if we told you that you can have it in the form factor of a
wristwatch offering from Texas Instruments
? How much would you pay for such a device? Quit guessing, you can
pick it up for just $49
with an estimated delivery in mid-February of next year.
Our tip-line has been packed with emails about this since it was announced on Monday. The device ships with the firmware to serve as a sports watch with heart rate monitor. The price is pretty good just for that functionality but this package also includes a USB programming and emulation dongle so that you can develop your own firmware. It looks like the included development software is written for Windows but we’re hoping you can get it running on other platforms as well.
The LCD is a segment display, so you won’t see
DOOM running on board
. That said, we expect your first project to turn this into a wireless controller using the buttons and accelerometer.

Keep the niche market happy, and you’ll never know when that next big order will come in from the engineer who now has to recommend a MCU for their company’s new product.

I don’t think TI is really targeting hobbyists at all with this particular system–I’ve been following this and some stuff on the msp430f5xx cores (which is what’s inside the cc430, iirc), and there’s been a crapload of silicon and debugging bugs with this chip. Hopefully they’re fixed by now, but I don’t think this is exactly for the faint of heart, since people have been having quite a number of debugging issues with the chips. Also, this chip is really designed for more integration and lower power, things that I’m pretty sure your typical hobbyist’s project don’t consider much. Keep in mind that if you’re doing anything in the watch form factor and actually want to be making something usable, you’re going to have to code very carefully to keep the power down.Heart rate monitoring might sound cool and might seem as if it might actually be just a fun hobbyist’s project, but I think this is actually a market TI is currently trying to create.Keep in mind, too, that gcc and all of the free unlimited compilers (and a lot of the not free compilers, too, for that matter) for msp430 won’t work at all with these guys–these are top of the line, brand new ICs, and I doubt any of the free software guys are going to bother updating their compilers anytime soon.",

Using An IPhone As A Newton Keyboard

[Jesus Alvarez] sent us this funny little project. If you happen to have an iPhone and an old Apple Newton, you can
use the iPhone as a keyboard for the Newton
. You can download the schematic from his site to build the wire to connect the two. After that, you have to run an app on your iPhone that you can find once you’ve jailbroken your phone. At that point you are ready to go. Aside from the ability to say you could, we’re not sure why you would do this. It made us chuckle though. Maybe we’re not firing on all synapses though due to turkey overload.

GSM Enabled Security Door
|

[
"gsm",
"lock",
"security",
"xbee"
] |
The security door at the front of [Oliver’s] building uses an intercom system to let in guests remotely. Each unit has an intercom handset with a button that unlocks the door. [Oliver] wanted a way to enter without carrying any extra items so
he built a system to unlock the door with his cell phone
.
He patched into the intercom and attached a GSM module. The module runs python so he wrote a script that will monitor the entryway buzzer, then wait for an approved cell phone connection to unlock it. He went through a couple of different iterations for the final project. The first attempt used XBee modules to communicate between the intercom handset and the GSM module. For the final version, he snaked cable through his wall using rare-earth magnets (creative!) in order to forgo the use of a battery in the handset.
Who doesn’t carry a cell phone with them? Because of this, the use of
GSM modules in automation
is a trend we think will continue to gain popularity.

Sprite_tm
] has whipped up
yet another interesting tutorial
– software-based this time. He basically describes how he connected his Wiimotes to an HTPC. A USB Bluetooth receiver, and a little bit of Linux scripting, was all that was necessary to get the system up and running. To add to the fun, [Sprite_tm] configured a the controllers to work with
MAME (an arcade machine emulator)
, allowing one to
play Duck Hunt
on a computer
in its full glory

[Tom Wujec] explains
how an astrolabe works
and its importance in our technological development. He argues that an astrolabe was the world’s first “popular computer”. It measures the sky and that measurement can be used to tell time, survey land, and navigate a ship.
Astrolabes are built from three pieces and according to [Tom], educated children in the 1200’s would not just have been able to use one, but could build one as well. Electronics have certainly made our lives easier, but there’s something powerful about such a useful yet simple device.

Modern people don’t know exactly when the sun is going to come up or from what angle because it doesn’t matter to their lives, and unless you were a captain on a boat a lot of it probably didn’t matter much to you 600 years ago either (although sunrise and set time might, but you’d probably look these up in a table rather than use an astrolabe to figure it out every day). Modern clocks are not only superior to astrolabes because of their accuracy, they also remove a lot of pointless information and process that made “getting the time” a real pain in the ass, by the look of it. Don’t get me wrong, they look like beautiful machines. But they are obsolete, and nothing of value has been lost information-wise because of their obsolescence.",

Well, obviously it would take some time so you would need a team to help code it. but you get my point.It also shows how people are becoming less intelligent, look back many years ago, everyone knew how to read, and they could do research. their is a lot of people that do not know how to read no more, and you sit someone in front of a computer these days and ask them how to make a little hello world program they would sit their and shrug instead of doing research for that particular question that was asked.Ok, i’ll shut up, iv gone way off subject anyway.",

We know that feeling, you’ve been up all morning working hard, and now you just want to relax. What better way than to sit back and watch as helpless electronic devices are stripped, forced to show their goods, then put back together only hap hazardly – not that we’re into that or anything. Today, we had one thing on our mind, game systems.
With the release of Pokémon HeartGold and SoulSilver shoppers were also given a device called the PokéWalker. A pedometer that helps your pocket monster gain experience and affection towards you.
Here is a tear-down
of the device next to Nintendo’s other try at getting children active, the Activity Meter pedometer. [Thanks Arty2]
Sega, while in todays day all we see is more and more rip offs of everyone’s favorite Hedgehog, we do remember a time when you brought more to the game field, especially with your advanced consoles. It does bring a tear to our eyes seeing
this beast being torn apart
, but its all for the best.
Those keeping up with Nintendo’s DS series will notice one thing, the console keeps getting smaller and smaller. That trend continued until the (Japan) release of the DSi LL. Some think its size can be attributed to an easier to see screen, others feel its jam-packed with more features. Make your own decision after seeing
its tear-down
. [via
engadget
]
Finally, we couldn’t decide what a fourth tear down should be, and couldn’t just leave with only three. So how about
10 separate Sony gadgets torn apart
!

Door Opening Help

For those who are seeking prosthetic limbs, or just require a little bit of robotic gripper help, the choices are very few and very costly. A newcomer to the area is hoping to change the costly part with their
door opening arm
. Costing only $2,000 to build, it is quite cheap compared to the other offerings. This arm can grip, twist, and swing its arm at the same time using a single motor thanks to a slip clutch.

Pay close attention. At roughly 36 seconds we see Asimov’s laws going out the window. We’re pretty sure we saw this little
autonomous battle bot
take a shot at a human. We can’t tell for sure, but it looked like it enjoyed it too.
This bot is being built by [xdream] to compete in the Mech Warfare section of the
Robo
Games 2010
. His target acquisition system and firing are completely autonomous. We think his motion is controlled by an operator though.
This little fellow may seem harmless enough, until you realize that those servos and guns could be replaced and this “little guy” becomes that “big fella”. That’s not anything the maker suggested, we’re just pointing out that a killer robot is only cute when it’s small.

mbed
is a next-generation 32-bit microcontroller platform. It’s a prototyping and teaching tool somewhat along the lines of Arduino. On steroids. With claws and fangs. Other contenders in this class include the MAKE Controller, STM32 Primer and Primer 2, Freescale Tower, and Microchip’s PIC32 Starter Kit. The mbed hardware has a number of advantages (and a few disadvantages) compared to these other platforms, but what really sets it apart is the development environment: the entire system — editor, compiler, libraries and reference materials — are completely web-based. There is no software to install or maintain on the host system.
The Hardware
The mbed board is sensibly priced at $60; about middle of the road among its peers. mbed’s size (or lack thereof) is among its greatest assets, measuring only about 1″ by 2″ (26 x 52mm) in a stout 40-pin DIP package that just barely manages to fit in a
breadboard
…a major win.
The top of the board is dominated by the microcontroller itself: a 60MHz NXP LPC1768 based on the eminently capable 32-bit ARM Cortex-M3 core, sporting 64K of RAM and 512K flash, and rounded out with an embarrassment of peripheral riches: Ethernet, USB (host, device, and to-go), CAN bus, multiple serial, I2C and SPI buses, 12-bit A/D and even a 10-bit D/A converter and realtime clock/calendar. Also on top is the USB connector (mini-B), some power regulation circuitry (operating on 4.5 to 9 volts DC, or USB power), several indicator LEDs, and the reset button (a plain vanilla tactile switch on our purchased unit, not the candy-like blue button seen in product shots).
The underside conceals an Ethernet transceiver chip (requiring only the addition of an RJ45 jack to get the board on a network) and a DiskOnChip-style component that provides a small (about 2MB) FAT filesystem when attached to a host system through USB, much like a thumb drive.
This latter feature — the FAT filesystem — is half of the key to mbed’s software-free, cross-platform magic. Getting new code onto the device is simply a matter of copying the compiled program (as a .bin file) to this drive. Press the reset button, and the new code is copied to the MCU’s internal flash and run. No special
programming hardware dongle
, no special bootloader software, just drag and drop. This has some serious implications. Pretty much
any
system these days can mount a FAT filesystem. We’re not just talking about getting Mac and Linux users into the fold alongside Windows…there’s also the impending wave of featherweight netbooks with ARM and VIA chips running peculiar, instant-on operating systems. Or the
OLPC XO-1
. Or older PowerPC Macs. The computers in the school’s lab that you’re not allowed to install any software on. Game consoles.
The Software
“
Cloud computing
” is still the hot buzzword this week, and the mbed project has adopted the concept wholeheartedly, comprising the other half of their softwareless strategy. Everything with mbed —
everything,
even your own source code — resides on their servers and is accessed through a web browser. This carries with it all of the good and bad points of any other network-based service such as Google Docs. There’s the potential for this to be a fantastic tool for teaching and collaboration, and in fact they’ve
created such an online community for mbed
, with forums and publicly-shareable code libraries. One can move between home and office, or
travel around the world
, and resume editing code on any system with a solid ’net connection. No need to check for software updates; the server will always be current.
mbed programs are written in C++ (yes, thankfully it’s “programs” and “C++,” not “sketches” or “the mbed language”) using their
JavaScript
-based online editor. When ready, click the
Compile
button. The compiler and linker run on the back end, on the server at the other end of the network connection. Provided your code is all syntactically valid, a compiled .bin file will then be downloaded to your computer…save this to the mbed USB disk, press the reset button, and you’re good to go. In Arduino-like fashion, the mbed device also appears as a virtual COM port, so you can monitor a program’s serial output using any terminal program.
The Good
We were taught that you should always say something kind before criticizing, so we’ll point out that the above process does, in fact, work exceedingly well, and has proved to be both quick and reliable. Once you get into the groove, the sequence of operations is no more onerous than with Arduino or any other microcontroller-specific programmer dongle.
To their credit, unlike some microcontroller evaluation kits, there are no artificial limitations to the mbed compiler; the full code and memory space of the processor is available to your code. The editor has realtime syntax coloring and multiple undo levels. And double-clicking on an error message in the compiler output will take you directly to the offending line, as in any decent IDE. You can import existing code from your local system to the mbed “cloud,” or likewise export individual files or an entire project. All good stuff.
The real saving grace of this setup is the libraries, both the official functions in what they call the “
Handbook
,” and community-contributed code in the “
Cookbook
.” A tremendous amount of functionality has been implemented in a concise and usually object-oriented manner. It’s almost comical sometimes, after having worked with other microcontrollers and girding for some expected coding nightmare, only to find that the corresponding library handles a task in a couple of lines (browse through the Handbook and Cookbook for examples). There’s a tendency also to follow stdlib or “UNIX-like” conventions for file access, character I/O, realtime clock access, etc., so existing systems programmers new to microcontrollers will feel right at home, no weird function names or syntaxes.
The mbed’s FAT filesystem is also accessible to the microcontroller, making it useful for more than just program storage. Web pages can be served from this space, or a
data logging
program can store results here. If the two megabyte capacity is too limiting for your needs, have a look at the
SDCard library
in the Cookbook — it’s almost trivial to wire up and use. Pretty much
all
of the libraries are like that!
The Bad and the Ugly
Hardware-wise, there are just a few minor nitpicks:
First is with the local FAT filesystem. Even though this is one of the device’s most unique features, and the very thing that enables its platform neutrality, the implementation just seems a bit anachronistic. The aforementioned SDCard library demonstrates how readily that format can be used. It’s faster, with the potential for far greater capacity, and cards could be easily swapped out for different code or data files. Not a major disappointment, just seems like an opportunity was missed to make this product even better.
Second is with the indicator LEDs on the board. Four of them, scant millimeters apart,
all blue
…making them pretty much worthless as status indicators from across the room, where they all blur into a singular blob. Ten years ago, blue LEDs were
novel.
Five years ago, they were
mainstream,
festooning every last USB hub, mouse, flash drive and imported piece of crap. Today they’re just
tired,
let’s get over it. Different colors would indicate status at a distant glance.
Finally, not a problem with the mbed board itself, but it would be nice to see one of the Cookbook projects, the “BoB2” breakout board, made into an available product. The blank board can be ordered through
BatchPCB
, but after postage and handling the price for just the empty board — no components — is $33. Have this populated and mass-produced, bundle it with the mbed in a $100 package, and it sounds like a winning setup, ready to go head-to-head with the MAKE Controller.
But really, those are just nitpicks. Our
real
beef is with the software…the code editor specifically. If you find the Arduino editor aggravating, the mbed editor will have you seeing red (or maybe purple if you factor in all those blue LEDs). Like Arduino, there’s no true tab formatting; everything’s expanded to spaces, like it or not. Auto-indent cannot be disabled, and there’s seemingly no command to increase or decrease the indentation of a block of code. If you’re accustomed to anything more than arrow keys to move and click-and-drag to highlight text, the editor disregards a lot of system-native editing behaviors that may be deeply ingrained in your muscle memory (such as shift-clicking to select a range of text, or triple-click-and-drag for multiple contiguous lines). What’s more, the quirky behaviors are a little different across each browser and operating system. Don’t even
try
that triple-click-and-drag in Firefox for Mac…you won’t get your text cursor back without a complete reboot (seriously, just restarting the browser isn’t sufficient). And at present, only the most common browsers are supported; all others are currently shut out.
The closed-source nature of the tools may also be off-putting to some. If one finds the Arduino editor distasteful, there are options: get in there and change the code, or simply use a different editor and link with the Arduino libraries manually…it’s all legal and encouraged. With mbed, there are no alternatives. Access to the compiler and libraries is “free as in beer,” but not “free as in speech.” There’s little recourse should the service ever be taken down, or if they should suddenly start charging a subscription fee (there’s no indication this is planned, just a hypothetical scenario).
The good news, at least with regard to the former, is that software is of course infinitely more malleable than hardware, and it’s almost certain the tools will improve with time. The site is under active development…new “Home” and “Notebook” features were added for registered users just yesterday. Perhaps, given time, they’ll get the Command key working properly on the Mac. The selection of user-submitted code will expand regardless, making it progressively easier to do more and different things with this board.
In Summary
The
mbed Tour page
is frank about what the platform is good for, and what it’s not. mbed was intended as a quick prototyping and educational tool, and at that it excels. A lack of features such as a debugger or offline compiler keep this from being a professional-strength development platform, which is okay. Think of it as Arduino: The Next Generation. Although the mbed board costs more up front than Arduino, there are capabilities here that would otherwise require costly “shields” and strain every last byte and CPU cycle of the 8-bit ATmega328 processor: Ethernet, USB, SD cards…mbed handles these tasks with aplomb.
mbed is not without its flaws, and the “cloud” development approach may never sit right with some. For a product that’s just weeks out of beta testing, the results thus far are extremely encouraging. There’s immense potential here: a seriously powerful chip, easy to interface and to program. If the online tools can be improved, or if open source alternatives become available, mbed could be a major player. We expect to be seeing a lot more of this device in future hacks.

I don’t think that it is intended for folk who are scared of the cloud and they don’t have to use it, they can use the old fashioned clunky stuff that used to blow my brain! After all, it is just an ARM processor but with a lot of bells and whistles.As for going bust, I suspect that is unlikely as it comes directly from ARM, Cambridge – hardly a fly by night company!The support guys are great, too.

Not being able to keep all your software at an unchanged, stable version is another pitfall. Even if everything works today, it doesn’t guarantee that the people that take over from the developers won’t mess something up, and there’s no version rollback the user can get at.BUT, negatives aside, it’s a $60-100 chip with a host of cool things to do. And it’s tiny. And it looks like they’re gunning for a good support system so people can piece code together lego style rather than writing it all out new every time.

[Ania] wrote in to let us know her team had finished the Multixylophoniomnibus and that
they have posted an extensive writeup
about it. We covered this
augmented xylophone
when it was still in development at the beginning of this month. Originally they wanted to use mallets wrapped in tinfoil as switches that close when they contact the metal keys, something akin to
matchbox cars as a switch
. This plan was thwarted when they realized the paint surface insulated the metal keys. At this point they switched to piezo sensors which turned into an odyssey of trial and error to achieve a reliable input for the Arduino to monitor. In the end they got it working with around forty lines of code, interfacing six boxes containing a different type of noisemaker.
See the finished instrument played in the video after the break. Alas, the addition of the piezo sensors do impede the resonance of the xylophone keys, but we still like it! There’s something reminiscent of the beginning of
Pink Floyd’s Money
when this is played.

A laser (a cheap $1 red one) shines on to that surface, and is reflected onto an LDR or a photoresistor.When they key is hit, the beam of the laser will fluctuate a little, this will cause some change in resistance, which can be measured.I know that the vibrations will be very small – however I have used a similar technique in a project I have done before to do with making a laser-audio-wall-bouncer-offer-spy-thing. It is workable.",

Tube Prototyping Station

[Gio] enjoys using vacuum tubes in his projects. He designs the circuits using a CAD program but was finding that there is no substitute for actually building a prototype before heading to a final design. To make this process easier,
he built his own tube prototyping station
.
At the top of the board he’s got three different sizes of tube sockets with the pins from each wired as common. The nine pins from the sockets break out to a terminal strip where they can be interfaced with a solderless breadboard. For added versatility he’s included terminals to tap into some RCA jacks, as well as a 100 kOhm variable resistor. We’d bet this is not something that you can find ready-made, but it sure does look a whole lot better than a workbench full of components alligator-clipped together.

It included a variac-adjusted power supply and several drawers of tube sockets and various discrete parts mounted on plastic carriers with metal pins for electrical connectivity. The front of the suitcase was lined with perforated pegboard; you snapped parts into the pegboard and connected the pins with jumper wires. The whole thing was so cumbersome and problematic that I only used the power supply, and eventually junked the rest. (Boo hoo!)It really highlights the sea change brought about by transistors; all that junk was obviated by a solderless breadboard you can fit in your pocket. Tube prototyping still requires a lot of fabrication and this guy has done a great job. A++ for literal breadboarding!

Remote Uses No Batteries

How often do you change the batteries in your television remote control? Yeah, basically never. But that’s a tribute to how efficient the device is and not a reason to overlook this development. NEC is showing off
a remote control that uses no batteries
. Power is generated using the piezo effect that occurs when a button is pushed. That is to say, when a crystal is compressed it emits a tiny bit of electricity which is harnessed and used to power this device. This is the same principle that is used in the
electricity producing sidewalks
tested in Japan.
It’s pretty phenomenal that they can run the device using this method. Right now there’s only a handful of buttons but we’re sure there’ll be advances in the technology. There’s a ton of use for this if it can be miniaturized. It is using radio frequency instead of infrared, making it a useful development in wireless doorbells, garage door openers, key-less entry fobs for your car, and many more applications.

As you can see above, there is no wiimote in that accessory steering wheel. There is, instead, a
home-made accelerometer controller
that connects to the pc via USB. Based around a PIC 18F2550 and a 2 axis accelerometer, this device is detected by windows as a standard controller. The schematic and source code are available on his website. He says it can also be used as a “motion mouse”. You can see a video of that after the break.
When we first saw the video, we thought it might be the same person as
the accelerometer controlled maze project
, due to the wiimote steering wheel casing.

You can’t run any time-critical code with it (because of the USB interrupts) and I have not been able to make it work when I use an interrupt-driven method (my interrupt service routine probably delays a more important one)It does work, and I’ve made an input device with it, but it really limits what you can do.",

[Maurice] let us know that his latest photography tool for hackers, the
Camera Axe 3.0
, is now available. The
original
allowed you to trigger a high-speed flash and camera from a multitude of sensors, including light and sound. The new one does all that, but also: allows multiple cameras or multiple flashes, clean up of software to make it more user adaptable, and the best (arguably the most important) part – cheaper components! All that and more under the Creative Commons that we do love so much. Keep up the amazingly detailed and just pure awesome work [Maurice].

This neat
accelerometer controlled marble maze
adds a level of fun to retrieving a gum ball. You have to first navigate the maze using a controller that has a dual axis accelerometer in it to control the angle of the platform. Though that does look like a wii accessory, there is no wiimote in there. Only after you have completed it will the gum ball machine dispense the candy. [Dan] constructed everything himself, which might explain the lack of “pits” for the marble to fall into in the maze.
More details on the build and source code are available on his page.

Regardless the candy prize sure does get the kids excited ;-)I considered having the gumball double as the marble but was a bit concerned about having it roll around on the dusty wood near glue and paint.

Another Stationary Bike VR Rig

[Shingo] shared his implementation of a
stationary bike as a virtual reality
interface. This is similar to the
Google Street View setup
we covered a week ago but goes a few steps further. They patched into the bike computer to pick up rotation of the bicycle wheel and added an accelerometer for directional control. This setup can navigate through Street View but the video after the break also details an interface with Google Earth and even the ability to navigate through Second Life, following your avatar as it bikes along with you. The use of a wearable display is far superior to something like the
SurfShelf
and really gives you a goal other than just some cold-weather exercise. So take this idea, patch it into a
wearable computer
and you’ve got the exercise setup worthy of the future world we’ve been promised.

[Jack] wrote in to let us know about a
project that creates a virtual microprocessor core
based on the ATmega103 by using a Field-Programmable Gate Array. Great, we thought. Here’s another rather esoteric project like the
NES on a FPGA
, but what’s the motivation behind it? We asked [Jack] and he provided several scenarios where this is quite useful.
Implementing the AVR core allows code already written for the chips to be easily ported to an FPGA without a code rewrite. This way, if your needs outpaced the capabilities of the microcontroller long after the project has started, you can keep the code and move forward from that point with the added capabilities of the gate array. Having the core already implemented, you then only need to work with HDL for the parts of the project the AVR was unable to handle. He also makes the point that having an open source AVR core implementation provides a great tool for people already familiar with AVR to study when learning VHDL.
With products like the Butterfly that this project is based around, or the
Maple
we’ve seen in the past,
programmable logic
for the recreational hacker is starting to get a little easier.

When An Axe Isn’t Enough

"final countdown",

"keyboard"
] |
[Chris] wanted a guitar with a keyboard but didn’t want a keytar. Like any good hacker he took a cheap guitar and a small keyboard and
introduced them to each other
. He moved the control knobs to make room for the keyboard and added the control circuitry from the keyboard to the top of the guitar’s body. A 9v battery is used to power the keys and something called “Chris Collins’ transformer trick” is used to amplify its sound. If you know details on this transformer, leave a comment and we’ll update the post. Take a look at the video after the break to see [Chris] perform the Final Countdown on keys and guitar.
The guitar is a Chinese made Telecaster clone and we think he’s the first one to find a realistic use for keyboards that don’t use full-sized keys. [Chris] apologizes for the lack of build photos but we give him a pass; he lost his phone while crowd-surfing and that’s as good an excuse as any for losing some pictures. We can’t wait to see another performance with this gnarly axe once he’s had enough practice to pull everything together!

[David Cranor] has
managed to fit
a fully working Uzebox system into an old NES controller.
Uzebox
, an open source gaming platform based on the ATmega 644 and an AD725 NTSC encoder, is one of a
couple systems
that are becoming
more
and
more
widespread and accessible. There are a number of
ready-to-go
Uzebox kits available, but for the more hands-on types, [David] has been very generous with his schematics and step by step instructions. These schematics can all be readily reshaped, and would easily fit into controllers with less
fun applications
and sentimental value.

Today we stumbled upon [jimthree’s]
Seismic Reflector
while looking at projects that employ the
Processing
language
we mentioned
a few days ago. Utilizing a Boarduino and some vibration motors from a game controller, the Seismic Reflector does just as its name implies – rattles itself around whenever there is an earthquake. While this does seem a bit silly at first, we were fascinated to learn there have been
165 earthquakes
just in the past week and almost no news reports, suddenly this device got a lot more interesting!

Outerspace: Reactive Robotics

While
Outerspace
may not have an extremely useful function, being an art installation, we really enjoyed reading through the build information. Basically, Outerspace is supposed to appear to be curious, exploring it’s surroundings and reacting to your contact. We do enjoy a
little bit
of
personality
in robots, so this seems like it could be fun. The head has 5 photo sensors and each piece of the “arm” has capacitive sensors. This allows Outerspace to sense what is going on. The motion itself is controlled by 4 servos in the base pulling cables that run through the body.
The programming seems like it could use a little work to achieve the effect of being “curious”, but we see potential here. You can see a
video of it in action here
.

[Robotkid249] details
how to build a wireless power transmission system
. This is similar to the commercial applications we have seen in a
TED talk
as well is in a
Sony prototype
. Power is fed to a ring made of magnet wire. A smaller loop is attached to the system that you want to power and picked up from the base unit. In this case, he is powering some LEDs but the concept can be tailored for your purposes such as an inductive charging pad. We’d like to see a hack that incorporates the base into a mouse pad (or the desk itself) and the receiver into the body of a wireless mouse. We’ve seen a
commercial solution along these lines
but we want one that doesn’t require a physical connection for power transfer.
[Thanks Juan]

If you make an oscillator that is tuned to the ratio of interaction of those two fields and utilize the principles of magnetics the only issue is then FLUX Density.

EM-theory still says r^-2, but people are smart I suppose.Does efficiency go to crapland whenever the sink and source are “parallelly” off-axis?

Which begs the alternate question: How does any energy propagate to a receiving coil?I have looked at Dr Soljacic’s (of MIT) publications – which are well beyond me. The answer is probably there, but hidden in the equations.Anyone?",

But now that I’ve read it through, I see where he’s asking questions like why doesn’t this set up work when the coils are perpendicular (remember right hand rule?). I also do not agree adding a joule thief was a good design decision. How such a circuit works with out a capacitor (I don’t see one) to store energy between the full-wave-bridge and the joule thief is beyond me. I also do not agree a square wave is the best power source. There are so many harmonics in such a signal I am betting he might see an improvement only because one of the harmonics makes the coil/capacitor combination “ring”. And there are other questionable design decisions like using the same capacitor value for both inductors even though they are physically different.One would think a sine wave at the resonating frequency of the coil / capacitor circuit would be the ideal set up. The equation has already been posted here for this relationship. But does anyone have a way of determining the inductance of a home wound coil (something simpler than a bridge circuit)?Someone else posted a question: Why doesn’t this follow the 1/r^2 rule. I think the answer is that we are dealing with resonating devices. The transmitter can re-absorb the collapsing EM field. So, in a sense, re-absorb some if not most of the energy (i.e. the resonating transmitter is oscillating between current storage and magnetic storage). If it were perfect, this would continue forever. However it is not and there is some resistance so energy is eventually lost. But we can replenish that by sending in some of our own current. But, I think, to efficiently transfer power to the receiving resonating coil / capacitor combo, we need to have the receiver tuned to the same resonating frequency. This way the receiving coil / capacitor can make full use of the ever changing EM field. That is, both the transmitter and receiver are collapsing & building their magnetic fields at the same time. I think, given the transmitter and receiver “ring” at the same frequency, the receiver will eventually oscillate as long as it can “see” the transmitter (i.e. it appears distance and position have little effect). I am betting the current you are able to draw off the receiver coil diminishes with distance. But if your load is light (i.e. a LED), you can probably get it working at quite a distance (more then the 5 inches in the original article).What do other’s think?Is this how it really works?",

He’s using coils out of that wireless mouse pad/mouse and a function generator.My instructable goes into the theory a lot more and I feel it adequately explains all the steps needed to make your own coils/oscillator. It’s super cheap, however the only requirement is that you own an oscillioscope. It would be really hard to make a usefull coil without one.Check it out if you’re interested:http://www.instructables.com/id/Low-Power-Wireless-Charging/",

[Texane] wrote in to let us know he has implemented
AVR ISP programming using a PIC microcontroller
. He wrote some code for an 18F4550 that uses the STK500 standard for In System Programming. This means that his hardware is compatible with
AVRdude
, the open source AVR programming software. There has long been an argument over the virtues of PIC versus AVR but we say why not both? If you have already honed your programming chops with PIC, you can build your own programmer and give the Atmel family a try.
The current implementation uses a serial port to connect the programmer to a computer. Keep your eye on this one as [texane] plans to add USB connectivity and has told us he will post schematics for the device as soon as that is complete.

Argh, Thar Be A Big Wheel

If you’re marooned on a desert island, you want to have a Professor who can build useful items out of coconuts. [LostMachine] is one of those guys, and he’s currently
building a land-loving pirate ship
. The wacky vehicle will use the giant wheel above to propel the vessel while the captain sits comfortably in the lofty crow’s nest. A crack-pot concept? Not really, he plans to take this to Burning Man where it will be a fairly useful build compared to
the folks who have really gone off the deep end
.
The story here is the build quality. Take some time to watch his videos which we’ve embedded after the break. In the first, he details his method for creating a precisely level building surface on top of his uneven driveway. This is accomplished by welding supports in a circle that are level compared to the center point. He goes on to share his liquid-cooling system for cutting the pipe supports with a custom-built jig and an old
windshield washer
water system pump from an RV (second video). The final video shows the construction of the wheel which came in with 2000 welds and about 250-300 hours of construction time.
If you hadn’t guessed, [LostMachine] is a structural engineer. Unfortunately he was laid-off this spring which has put a damper in his building schedule. We hope that with a quality project like this in his portfolio a new job is just around the corner for him.
Creating a level surface on an uneven driveway.
Cooling jig to cut fish mouthed joints in pipes.

[NeZoomie]
built an RGB mood lamp
as his first electronics project. He certainly hit it out of the park with this one, ending up with a design so clean it could be a commercial product. The controller is an Arduino board (further proof that this is a fantastic entry-level platform) that interfaces with 8 RGB LEDs. He’s built an enclosure out of thick polypropylene that does a great job of diffusing the light and adding a stylish look. The control system features a
rotary potentiometer from SparkFun
and what he calls a tilt-potentiometer of his own design after
drawing inspiration from Hack a Day
.
Blinky things are fun and that’s why
we see
a lot of
mood lamps
around here. Take a look at the video after the break and if you’ve got the parts, give this one a try!

[Harm’s]
tumbling robot
from a few years back is an excellent study in simple motion. Foregoing wheels or legs, he uses four flippers to roll the robot around the room. Two motors are used, each in charge of two flippers. Identical but separate circuits drive the motors with a 74HC240 gate IC monitoring the continuously rotation. When a flipper becomes stuck, the circuit reverses the rotation of the motor so the simple bot can tumble its way out of a jam.
The circuitry is less advanced than some of the
BEAM builds we’ve seen before
. That doesn’t diminish the cleverness of his design and we think
BEAM robotics
are great way to get your head out of the computer code and go hardware only. After the break you can take in some video of the tumbling motion. We’ve also included a video of another bot from his website that uses concentric rings for another type of unique locomotion.

[Harm’s] ‘W’ bot uses concentric rings for locomotion.

Banned Xbox 360’s – Boon Or Bust?

We’re sure you’ve heard about
Xbox 360s facing an other round of bans
from Xbox Live last week. It seems that living in a hole, or even in
Grenora, North Dakota
couldn’t help you escape hearing this from every news source possible. Apparently, this has caused
a slew of banned consoles to go up for sale
in a buyer-beware quagmire. This is a joke in several ways; didn’t the
hardware problems
of the machine already make the used market risky enough? Now
consumers will be even more wary
, losing game sales because less people are buying used consoles.
If you have just the right kernel, and a copy of your CPU key, and a second unbanned Xbox 360, you may be able to
reactivate your machine
. But how many people have those things available to them? Undoubtedly an Xbox 360’s desirability is greatly diminished if Xbox Live is removed from the equation. This is something Nintendo could learn from when it comes to the Wii (no online multiplayer with New Super Mario Bros Wii?… Really?). So whether you are the one who was banned, or you decided/were tricked in to purchasing a banned console, what are you going to do with it now that online play is out of the picture?
We’ve seen the console
emulating SNES games
and even
XBMC run with the help of Ubuntu
. Leave us a comment and tell us if you are planning to just go without Xbox Live, use the machine as a desktop running Ubuntu, or spearhead the effort to repurpose this powerful (and flawed) hardware platform. Will you go out and capitalize on cheaper hardware, or have you been burnt by the grim reality of a crippled rig?

The Xbox 1 got an enormous boost to it’s functionality, you could mod it for free if you had the right tools, and then you were a spare hard drive away from a small, cheap, TV ready media server, that could also play Xbox 1 games and emulate all the classics from PS1 on back. You had to give up Xbox Live but unless you were a hardcore halo fanatic the choice was simple.On the Xbox 360 the console is practically crippled of all the features that make it a great console when you lose Xbox Live, and beyond playing burned copies of games you didn’t get any extra functionality out of it. Setting up something like Ubuntu you had to jump through hoops to make it work and keeping your firmware that old you ended up losing the ability to play most games too.MS did really shoot themselves in the foot over how they practically advertised the bannings though. I’ve got non-gaming co-workers coming up to me all day asking me questions, worried that their kids going to get their console banned…Now that they’ve finally managed to shake off most of the bad RROD press they’ve got people thinking that they could get bannned from “opening a spam message” or “downloading a virus from the marketplace” (yes those are actual fears I was presented with from people I work with).I love the Xbox 360 as a gaming console, it’s just not worth hacking IMO.",

While it isn’t easy to mod an 360, it is still a powerful piece of hardware for the price. Now that there are dirt cheap systems floating around that are “crippled”, those interested in the hardware rather than the software will be able to experiment more easily. For $100, a banned 360 is still one hell of a machine, even if it can’t play games. I tend to agree that the system really isn’t worth hacking, but only if you want it for the intended purpose of playing games.I think M$ will soon realize that they have opened pandora’s box. People are more willing to experiment with stuff that is already broken. So if a killer app (like XMBC) comes out that actually has people buying consoles with the intent of using for a purpose other than playing XBOX360 games, M$ will lose a huge chunk of change (assuming they still lose money on hardware sales).",

If the stars were to align against MS (all banned users filed a lawsuit, won said suit, and were refunded the cost of their 360 w/ 12 months live gold service) it would cost them around $950.5 million (averaging a cost of $350 a console and $50 for 12 months of XBGold).According to the last 12 months of stocks, MS has made $13.77 billion in net income. While a suit would definitely hurt them, I think a loss of revenue from game licensing and XBlive subscription revenue would hurt more. The settlement on a suit would be a one shot deal, while loss of XB Live customers is a loss of steady revenue.I was wrong before. MS has made money from console sales since 2006-2007 ish time frame.Finally, I apologize for this boring financial rant. Yes, I know this is a site about hacking.",

"content": "i was banned week before last, brought new xbox wednesday just gone, reflashed it and signed up another live account, run mw2 through abgx360 let it do its business, rewrote the image and within 24hrs was barred again. took xbox back and said its not compatible with my requirements got a refund and brought another one. have flashed it but kept it offline until liteon lite touch is released. in the mean time i did some thinking now that i have spare time on my hands(banned) ”so long story short i thought to myself well my xbox lan can still connect so why not setup my own game server so atleast my and my family could still play together online. after some exstensive reading i came across this websiteCode:http://www.teamxlink.co.uk/who had already beet me to it. i can now play cod4 mw1/2 plus many many others online with other people across the world just like i could on xbox live, i had doubts and thought 1) it would be difficult to setup 2) it would be slow n sh*t.. how wrong was i. its great just like xbl ..here are a few steps to be online in 10mins.but first you need the following things:1:desktop pc with internet access(i used my laptop as it was easier2: a wrouter3: a xbox 360/ or psp and many other consoles. banned or not it dont matter4: a internet connection (your reading this so you have one)STEP 1:basicaly you put rj45 cable from xbox 360 to router, you put rj45 cable from laptop/desktop to router. you put rj45 cable from modem to router, so basicaly same principles as streaming movies from laptop to xbox360. goto your xbox dash and check network connetions to make sure your xbox can see and connect to your pc, because everybody has differnt hardware im not going to go into too much detail about how to network your xbox. you will have to disable any firewalls etc etc. once you establish a connection from xbox to laptop then move onto step 2STEP 2: gotoCode:http://www.teamxlink.co.uk/and download 7.4.18 xlink kai software. install software then return toCode:http://www.teamxlink.co.uk/and click sign up link, you need to make an account but dont worry its completly free..step 3 goto start menu/xlink kai/ and run the config check through the settings select the network adapter you are using( it maybe possible to use wirelss but i had trouble so hardwired) put in your username and password. change any options you think may suit you. save it an exit.step 4: start kai user interface and in the top left hand corner you should have a little magnifier icon click this and it will give you a diagnostic of your connection you want to look where it says connection reachable = if you get a YES then your home and dry and ready to play. if it doesnt say yes unfortunatly you have done something wrong try posting your problems here and as a community we can help solve issues. if it does say yes then goto step 5STEP 5: log into a local arena, ive only tried europe/uk rooms i dont see why it wont connect else where, but there has always been games available to play so not needed to try any others, once you have found a room with a few players online, insert your mw2(for instance) and goto multiplayer mode. then goto system link and join game, a list of available games will be presented, join and away you go, online gaming on all banned consoles lolyou can set up hosts games or join already running games.. its 2:38am sunday and theres plenty of games online, my gf is playing it as we speak…sorry if this tut is a little hard to understand but ive only just joined it tonite so a little cloudy as to what to do myself, but i can promise you, you will be online gaming in under 15mins.please share this information to anyone who is banned, the more poeple who join the more fun we can all have…also sorry for any spelling mistake, am rushing it so i can get back online..",

This isn’t the normal kind of cheating that you find in a game, but rather trainers that you download to your pc, then when the game console goes through your computer, it also goes through the trainer too.I suggest you do your homework on google.com before you just go and use these programs.

Here’s something that the R/C airplane crowd might think of as old news. These directions show us how to rework floppy drive and
CD Rom motors to be high power airplane motors
. There are several listed, with details on each, but those unfamiliar might want to start with the most
basic CD Rom version
. It covers winding your own copper and installing the magnets in the “bell”, putting it all together and mounting it. This is a great writeup for those who haven’t seen this done before. If you want something even simpler though, you might enjoy the
homopolar motor post
. If you’re more advanced, they have tips for you too on machining and balancing the motors as well as winding density.

Omni-car

We stumbled onto one of [Nik Melton]’s projects, an
Omni-car
. It is omnidirectional, meaning it can go any direction at any time without having to turn. The body was designed by him, then printed with a 3D printer. The control scheme is what interests us though. He has found a simple way to wire it to get the job done. Sure you can see that it suffers from some pretty bad “drift” when trying to go in a straight line, but overall, we think he pulled it off well.
You might want to take a few moments to look around his project page. This guy has done a bunch of fun stuff like delta robots, strange hybrid wheel/leg robots, tesla coils, and arm mounted flamethrowers. Judging by the videos, he’s pretty young too. We think his guy has a bright future ahead of him.

With the omni-wheels having perpendicular rollers, I would think you could just drive each pair of parallel wheels for your four primary directions — that way two wheels would be stationary (and perfectly perpendicular to the direction of motion).Basically, reconfiguring the electronics so that back/forth on each pair of parallel wheels would be controllable, rather than all four wheels being driven relative to one another. When you drive the “left and right” pairs “forwards”, you could get diagonal motion by driving the “front and back” pair one way or the other (resulting in what is currently “forwards” motion).Essentially, the primary drive mode would be what is now a “diagonal” drive… did that end up making any sense at all?",

[Jonathan Ward’s]
pcb mill
is as impressive as it is inexpensive. Twenty-six plywood parts, labeled A-Z, are used to assemble the machine along with the customary precision rods, stepper motors, and router assembly. His
bill of materials
prices the unit at $458.18, a small price to pay in order to forgo a
multi-step etching process
.
His test board shows some fairly fine pitch that could turn out most home-project circuit boards. We’ve contacted [Jonathan] regarding the specifics of milling the plywood parts out of a 2 foot by 4 foot sheet of plywood. Watch for an update with any information he’s willing to share. We hope he’ll make the milling files for the plywood parts available so that you can build a copy of the device for your own use.
[Thanks Charles]

Besides going elsewhere, you could consider going with normal threaded rods, nuts, and shafts instead of “acme” and “precision”. It’d be a little less accurate, but a lot cheaper.

I have my own homeade cnc that I’ve been using for a year now with good results.My experience w/ driver boards:In the process I went through 3 driver boards. First, a cheap “MDfly” board from ebay that burn up every driver IC and never worked. Second, a Xylotex board that burn one driver IC. Tried to repair it but it’s an SMD IC and I ripped up the traces upon trying to remove the IC. After talking to the guy at xylotex, he basically said i was screwed and wouldnt offer me a replacement board for $70 (he usually does if you’ve already paid 150)…this really ticked me off since he doesnt even repair the boards, he just sends new ones.The board I found to be the best was the last one i got here:http://cgi.ebay.com/3-AXIS-CNC-ROUTER-OR-MILL-STEPPER-MOTOR-DRIVER-BOARD_W0QQitemZ330379816955QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item4cec2beffbIt’s a very similar design to the Xylotex board but it offers one major design advantage: Sockets for the driver IC. That means if you burn one up (it’s super easy) you can pop out the burnt one and replace it with a spare for $4-5 instead of buying a new board for 70-150.So far I haven’t burnt any more up but I at least know I’m safe and the board works perfectly with my 3 axis setup.I’ve yet to mill PCBs because my machine isnt that precise/level yet.I’d be interested in buying a kit with the precut wood pieces, btw.",

In the UK, like many other countries, there is a huge hobby/cottage industry market. This machine would go down a storm if someone could offer kit/pre-built and good aftersales support. I make between 10 and 50 circuit boards a month using the photo-resist UV/developer/ferric chloride method – messy and time intensive. I’m sure I’m not alone in thinking that this is a perfect gateway product for a user to ‘get into’ CNC milling.

SparkFun Product Used For Immoral Hacking

While we have our fun ethically hacking, its very easy to forget that sometimes our ideas could be used with
malicious goals
. Take for instance SparkFun’s
BlueSMiRF
– the device’s original intention is simply to act as a wireless serial cable replacement. After hackers discovered several PIN pads use a serial interface, they put one and one together to steal several hundreds of people’s personal bank accounts.
It seems SparkFun is getting a lot of
heat lately
, but we’re glad they stand up and address these issues. You can check out the original
news clipping here

Automatic Pneumatic Drum Kit

Move over
Steve
and
PEART
… there’s yet another robotic drummer in town. [Fauzii] tipped us off to his own MIDI-controlled creation –
WizardFingers
. According to him, WizardFingers is already capable of 64th note rolls at over 250 beats per minute. That’s on every drum simultaneously. Each drum is hit with a lever attached to a linear pneumatic actuator. A laptop running
MAX/MSP
generates MIDI sequences, which are sent to
Doepfer MTC64 board
. All of these actuators are hooked up to the board, which sets them off in sequence.
[Fauzii] ultimately hopes to develop AI software that will allow WizardFingers to compose its own tunes on not only a drum kit, but bar chimes and an organ as well. His site documents the whole concept quite well (just watch out for wild cats).

As drummers all know, drums and cymbals make different sounds depending on where you hit them and how hard you hit them, and these systems all ignore these fact. A fixed hammer actuated by a solenoid is never going to sound like a drumstick wielded by a human. The striker needs to be able to move in a plane parallel to the drum head, and it needs dynamic control. Even that completely ignores the different kinds of strokes that drummers can use: you can hit a drum and let the stick stay just bouncing on the head, for example.This system includes a hammer *underneath* the hi-hat, which really makes me cringe; it belies near total ignorance of the dynamics of that instrument.

Then, as oft happens the band fell apart and the drummer was subverted by Art to be involved in some dance performances.To clear up a few things about the test videos, the software system was generating the drum patterns autonomously.

That title’s a mouthful but you’re already familiar with the technology and application of foot pads as sensors in games like Dance Dance Revolution. The
usbddr project sought to make a USB connected DDR controller from scratch
. The microcontroller used is an Atmel ATmega8 running the V-USB firmware for connectivity and uses the analog to digital converts to read in data from the capacitive sensors.
The physical implementation is cleaver. The base plate has a capacitor plate attached to the top of it and the tile has the other capacitor plate attached to the bottom of it. The two are separated by some weather-stripping which is spongy enough to allow compression, bringing the two capacitor plates together.
We’re not convinced of the long-term durability of the system. We certainly don’t think it will hold up to very much hard-core DDR playing. But we would love to see a Super Mario RPG style puzzle to unlock the door to the ‘castle’ at a child’s birthday party.
[Thanks Hans]

"content": "@bobYou probably want Piezo-electric rather than capactive for that. Measuring the capacitance between two plates like this consumes electricty, whereas systems that have the plates squishing down on piezo-crystals generate electricity.@andrewNot sure – but I think the screws line up with the sleeves below. On pads I’ve made the screws go through a hole drilled in the upper plate, and secure to the bottom. The upper plate then slides up and down on the sleeve / screw combo, held up by the foam, but held down by the screw head. I’m not certain how this configuration would work.@mowciusThe trick with DDR pads is that most players are used to a bit of flex or give to the pads. They how much pressure it takes to trigger the buttons, and at higher difficulty / speeds don’t move their feet much off the pads.One would have to very finely tune such a capacitve system to pick up intended inputs, but not force the players to lift their feet higher than on other pads in order to avoid unwanted button presses.Add in that different thicknesses of shoes / socks / bare skin / body type and you’ll be re-calibrating every time you step up to play.Using two plates with known characteristics avoids that whole mess.",

"content": "What do you mean they won’t last long? It’s an effing capacitive sensor–the contacts won’t ever wear out, since there are no contacts! The limiting factor is the weather stripping stuff, which I suspect has too low modulus of elasticity (everyone makes this mistake–it feels squishy when you push with your fingers, but when you put 150+lbs of weight onto it when you’re doing DDR, you’re driving it well into the plastic region of the material and permanently deforming it–I used the same technique to sense force for a project a couple years ago).Also, by “capacitive sensor,” unless I’m mistaken, they’re using this system to sense the capacitance between the two plates, NOT the capacitance of the person standing on top of it. This has NOTHING to do with the permittivity of whatever’s on top of the sensor. However, this is one very important aspect of the sensor that has been missed in this design–the shielding. There needs to be grounded shielding layers on the top and bottom of the panel, preferably spaced at a much grater distance than the two sensing plates, to prevent the sensors from picking up any changes in capacitance due to nearby objects (i.e. your feet or the floor the sensor is standing on)",

"content": "Having worked at a Gameworks in my early 20s, I’ve had the “pleasure” of cleaning and repairing these blasted machines. There were four pressure sensors (essentially switches) on each tile, 32 sensors in total. We had two of them, and even knowing what you were doing, it was a two hour job keeping the pair of them going per week. This design also benefits from there being more support on the tile; we had to replace a lot of cracked tiles from over-exuberant “dancers” and I’m sure that this design would protect the tiles better. As mentioned above, I agree that the upward screws on the corners are a BAD idea; the original has diagonal brackets to hold everything together with two screws at each corner pointed downward and that worked decently well. Not to mention that if this thing breaks down you’re going to want to be able to dissect it, and the brackets will make that easier. Finally, as threepointone mentions, I agree that while the sensors will be a ton more sensitive, they will become less sensitive with time, as the weather stripping gets more and more compressed, and will have to be replaced. I say though, better to do that than to replace four pressure switches per tile.",

"content": "I’m the author of this project and just want to add a few words to clarify things:capacitor design: As threepointone already mentioned, the distance between the two plates (one glued to to upper tile, one glued to the base frame) is measured. To avoid any disturbances, the upper plate is _always_ connected to ground (so capacitive influence from a person standing on top doesn’t matter), the lower plate is connected to a portpin of the uC to measure capacitance. I didn’t notice any disturbances so far.I also implemented a calibration function in the firmware: You press the calibration key, press each tile fully (by standing on them), release all tiles and press the calibration button again. The maximum (title pressed) und minimum (tile released) capacitance (for _each_ tile individually) is then stored in the controller’s internal eeprom and used in the calculation during gaming. I also connected a small pot to an adc port of the controller. The firmware allows to adjust the threshold level (at which point a tile is detected as pressed) with this pot during gaming, so you can change the “responsiveness” of the pad to your needs.mechanical construcion:The pad was mainly build as a proof of concept for the firmware and circuit, so I just took stuff I had laying around. It is certainly not _THE_ best solution, but feel free to improve it (and mail me ;-). And yes, the wheaterstrip is the only thing that wears off.The screws in the wooden tile align with the sleeves, that’s my quick’n’dirty method to keep the tiles in place. Again, not the best solution, but it works ™.Have fun,StefanP.S.: You can drop me a mail at srehm (at) lavabit.com if you have any further questions.P.P.S.: I’m not a native english speaker, so excuse any misspellings :)",

The portpin is switched to input mode with internal pullup resistor on, “slowly” (as in microseconds) charging the capacitor until the portpin reads a logical ‘1’, the time needed to do is is proportional to the capacitor value. Then the portpin is switched to output mode and set to ‘0’ to discharge the capacitor.In short, apart from the protective capacitor, there is no external hardware, the capacitor is directly connected to a portpin (not to an internal adc as the announcement says).",

Hacklab’s laser cutter got the customary musical treatment. You can
see it play the theme from mario brothers
here. It’s
nothing new
to us, but we still enjoy seeing it done.
Ever been curious how a pole transformer is made? Quench that curiosity
with this educational video
. [via
HackedGadets
]
Here’s a quasi humanoid robot that is
designed to be your workout trainer
. He’ll show you the exercises, give you motivational and encouraging pep talks and even play games with you. We think the idea sounds good, but in execution, he flails his arms and randomly says creepy insincere sounding things like “I’m having fun. I could play this game all day long. I’m having too much fun.” That’s just creepy.
[Mr. Nelson] got sick of walking all the way down the hall just to see if there was anyone in the bathroom. His solution was to
build this massively overdone indicator light system
. It uses a proximity sensor located in each bathroom to determine occupied status and has a fantastic industrial look.
If you’ve ever wanted to get into 3d photography you’ll be pleased to see this writeup on
how to build a simple rig
and compile the images for different viewing methods.
We were amazed by these
beautifully crafted brass machines
. The one in this video is solar powered and seems to run pretty smoothly. Not bad for something that was all hand crafted from sheets of brass.
Be careful with this one folks. This video shows how to
melt a beer bottle in your microwave
. We’re not sure why you would want to, but we sure enjoyed watching it happen. Maybe that’s reason enough.

Build A Camera Boom At Less Than A Grand

"junkyard wars"
] |
The folks at The Geek Group
built a camera crane for less than $1000
. In the video embedded after the break a presenter takes you through the different parts that make up the boom and how it is operated. This feels like something from a
Junkyard Wars
challenge as most of the parts are scavenged or from an industrial surplus store. Don’t let that sour your opinion, what they’ve ended up with is amazingly functional.
The base of the unit is a rolling tripod used for television cameras from around the 1960’s. The aluminum boom attaches to the base with a few large bearings and features a fine tuning balance system. The camera mount is motorized and can be moved using a joystick or set to scan automatically. It’s nice to see more examples of
custom camera mounts
. Obviously this isn’t a build for everyone, but as cameras and camera equipment become more readily available it makes high quality video production available for the masses, not just the networks.

[Satiagraha] let us know that Texas Instruments(TI) has given out a neat “
LED Reference Design Cookbook
” PDF. The document contains 17 some odd little projects featuring different TI ICs and ways of using them to control LEDs in things from
backlights
to
torches
to
solar lanterns
to
advanced PWM control
! Sure the document is biased towards using TI equipment, but that shouldn’t stop you from recreating, modifying, and generally just having fun with their designs in your own productions.

RFID Door Lock – The Right Way

[youtube=http://www.youtube.com/watch?v=XT7E_GEIPVg]
[Pcmofo] has shared a well-built, well-explained example of
how to implement an RFID key system for a door
. We call this the right way because it is well thought out and functional. In the past we’ve seen doors that unlock
via a secret knock
,
keypads
, and
RFID
, but they are all non-permanent solutions capable being transplanted from one door to another. Rather than building a mechanism to turn the door handle, this implementation uses an electric strike mounted in the framing of the door to allow access. These are used for security doors in buildings and are built to keep your door secure.
The hack in this case is the electronics. Using an AVR ATmega168 running the Arduino boot-loader, [pcmofo] has prototyped a two-part design. An RFID reader is mounted outside the door with data wires running to the inside where the microcontroller resides. A hard-coded RFID card is used as a “master” to train any number of tags for entry. The master puts the device in training mode and the next tag to be read is added to the list of tags authorized to open the door.
We like messy wires and quickly thrown together devices but this is built to last and will look great once mounted in an appropriate enclosure.

Security is really a deterrent as nothing is completely secure. This RFID circuit can be used on a number of other more secure locks or locations. The primary goal of this circuit and installation was to create easier access for myself and friends who may need to access my garage. The Reader will be mounted near the handle so a RFID card in my front pocket wallet will allow me to unlock and Push open the door while carrying something in my hands.I am trying to make a prototype PCB next before having one professionally made. I can make the reader fairly easy, still working on the controller layout though.This is the door to my garage brewery. It is where I am working on my current project involving beer + electronics.

You’re probably more likely to destroy the door frame. It’s often possible to retract the deadlatch with a screwdriver when there’s an electric strike, because the electric strike has play in it that allows the deadlatch to fall into the strike. In the video above, though, the door opens inward, which means you can’t get at the deadlatch bolt from the outside, so it’s not a problem.More info on deadlatches:http://www.ehow.com/how_5131900_check-deadlatch-feature-lock.html",

Total this project is less than $75 which is less than most electronic door locks you can buy and can work with existing lock setups without needing to replace the entire lock.Ozzi: your right about the latch. Your going to need to kick down the door to get around this, which I’m sure you could do with any other lock. But like I said, this could be used with any type of lock, it could replace a safe lock, you could use it to control motorized deadbolts etc. Modify what I have done and make it better!

This type of RFID card is not secure, having a reader on the inside to read and validate cards so that the master card is not cloned will not prevent anyone from cloning another users card. The master card can be kept in a safe place so it is not out in the open to be cloned. I am using a second card as a master erase to erase all of the stored codes in the event someone loses a key etc. There is no easy way to manually delete cards from the system individually.Then again I could add a networking adaptor and have a server record all ID’s and users names in a DB then be able to selectively delete users or limit access time and log everything…. but then again thats far outside the scope of this project. Maybe in the future. Currently making the RFID more secure adds no value to the project as the physical structure is still the weakest point.As I said before, this project could easily be adapted to many other projects. I wrote the code to handle error checking and validation of the RFID cards so their were no transmission errors etc. You can easily modify my code to make the system do whatever you want when a valid card is read.I plan on doing more RFID based projects so their is a chance this will be enhanced in the future. For now I think this would be both a fun and useful project for most people.",

I asked what would happen if the system lost power (breaker tripped, bad power supply, lost utility power, etc) and could I then just walk up and open the door. It took a minute for it to sink in why that might be a bad thing, especially when a fail-secure system can still be opened from the inside with a knob in case of emergency, you just can’t get back in without a physical key.",

I am not sure about just the motorized deadbolt itself. You can program the length the door stays open or anything else very easily openDoor(seconds);Yes no matter what I do short of reenforcing the door this is not going to be secure. It does not make it any less secure than a standard deadbolt. Picking the lock and brute forcing the serial connection are equal. Then again I could easily add brute force protection making a user wait 1 minute after swiping 5 invalid cards and locking them out longer each time additional invalid cards are swiped…. or connect a security camera that sends me a picture when an invalid card is entered…. etc etc….Yes I called the transistor a transformer….. I shot the entire footage on the iPhone and edited it on the iphone and uploaded it to youtube via the iPhone so I missed that error. I think the schematic and other details covers this mistake as no one will be building this circuit from the video explanation alone.Thanks everyone for the positive comments!",

We ask, who wouldn’t want a rotating motion and distance tracking radar? Sure in today’s day and age anyone could purchase a wide-angle sonar or IR solution that achieves the same goal, but [LuckyLarry] took it old school and made his own
rotating radar
. He used an Arduino, servo, and ultrasonic sensor as a base to gather data, and the open source programming language
Processing
to draw the data on the screen. He says it’s a little inaccurate currently, but will try out some other sensors in the future.

Instead of it plotting a point at the distance the signal is bounced back at, it fills in the area green until it his a target. So in the video, that green blob is showing the varying distances between the objects in front of the sensor.So that indent to the left side of the display is the flat surface of the book, which is closer than the bottles.Not sure why he chose to render it that way, as it seems harder to read than the more traditional output. Plus it doesn’t help that his scale seems to be set for a much longer distance than what is necessary for this test.",

It would be cool if he had a button or something to adjust the displayed range.

I’m curious whether it’s at all possible to resolve two targets at the same azimuth but differing range with sensors like the one used here.Hope to see future improvements on this project.———————————————–I still don’t get the problem so many people have with Arduino.

"content": "I think the point of people who complain about arduino projects is that using electronics to build a project, while interesting in it’s own right, is NOT a hack. The site is called Hack a Day, not Project a Day.That being said, personally I enjoy seeing all the projects, and think the people who are stuck on black and white pictures, who are anti-ardunio, and who are only happy when someone truly hacks something, are being too picky and naive. If this site turned down every project that wasn’t strictly a hack of existing devices made for a completely different purpose, it would be far less interesting. IMO of course.At least it would be for me because I couldn’t care less what OS someone decides to put on their roomba or if Linux can run on the new DVD player they just bought. Hacks like that don’t have much purpose except to say “I did it”. That has it’s own worth sometimes, but surely we can all agree that Linux has been put on everything, and will be able to run on everything in the future, so it’s not a novelty anymore.New electronics projects, arduino or not, are interesting to see. I consider adding traditional new electronics projects to the mix here a good growth move. Maybe a name change would make sense, but why go through all that just to satisfy the people who can’t get over it?And yes, I know there are some crap projects here and there, but you don’t HAVE to read them. Read the headline and if you don’t care for the project then move on. I know I certainly wouldn’t want to be responsible for filling up a site like this with content. So I leave the guys that do it alone and enjoy the gems that crop up from time to time./pointless rant",

USB To Serial Adapter

[Spikenzie] is at it again. This time he’s posted a
nice USB to serial converter
. He points out that you can buy a USB to serial adapter pretty cheaply, but sometimes you want this functionality built into your project enough to justify the greater cost. In those cases where you want to integrate it, this is an elegant solution. This design was made to be fairly compact and still usable on a breadboard. As usual, you can download the files from his website. If his work looks familiar, it’s because we’ve covered his work
several
times
before.

Difficulty: RH7 installer needs a lot more RAM just to uncompress own packages and has no alternative of installing from floppy. Therefore, must code a custom installer. That was a decent adventure, and the thing was heavily used afterwards almost for a year; however now I would begin from busybox and its built-in tar — perhaps less coding involved.Your dinosaur could be saved by a null-modem cable. Win95 probably doesn’t contain intersvr.exe and interlnk.exe, which surely were available in DOS 6.22. However there is the standard “Direct cable connection” driver.Interfacing those disks is another story. I once fried a 20 MB disk from Toshiba 1000LE (a 10-MHz 8086! MS-DOS 3.2!! 16 shades of gray!!!) just by trying to access it from a recent motherboard. The wiring adapter was used earlier with a recent 2.5″ disk so it’s not an electrical problem. Just to be sure, I found the official pinout of that bastard beforehand – no significant differences from contemporary IDE. Ergo, mere ATA protocol differences killed it :( Now the thing boots from floppies only. Shall I upgrade the BIOS chip to a Flash one and start reverse-engineering its contents so that newer disks are supported? :) A ludicrously messy job, and of little value: even arduinos now have more processing power.",

LED Ring Light

"ring light"

[Jani]
built his own photography ring light
based on automotive LED rings. The rings he used are meant to encircle headlights on a car and are available at a low cost. The assembly is built around a filter that attaches to his camera lens. Two rings of LEDs are then glued to a case made from the plastic of a CD-R container. To diffuse the light, he sanded both sides of the clear plastic housing to make it translucent.
LED rings operate on DC power and unlike
a ring flash
, they provide constant light to help set up your shot. His finished project is well-built and should come in between $10-20.

An exhibition
just wrapping up at the Russian Frost Farmers Gallery in New Zealand presented an interactive artwork hack. Called the Radio Assisted Drawing Device (R.A.D.D), it is a plotter that mounts on the wall. It isn’t computer controlled, but rather relies on a remote control with two sticks to move the plotter
Etch-a-Sketch style
.
A clear gantry mounts vertically and travels along the top edge of the wooden backing. A slot cut in the acrylic steadies the plotter and allows for smooth vertical movement. Obviously built by hand, the mechanics seem to have tight tolerances for precise movements of the stylus. See the exhibit in the video after the break.
Wouldn’t you love to have one of these on the wall at your next party? It adds a whole new spin on a guest book.

Tauntaun Costume

[Scott Holden] went all out this year and built an amazing
Tauntaun costume
. The
Tauntaun from Star Wars
was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.
Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.

[Blacklight99] made this cool tool. It is a
tester for those radar detectors that people keep in their cars
. Though this seems like it would rarely be a tool we would need, it’s an interesting project. Some speed guns that the police use have a “stealth” mode that makes them invisible to some detectors. This tool can tell you if your detector is vulnerable to this. While this really is just a complicated flashing LED, he notes that it could be taken further to be made into a detector that is programmable and not vulnerable to any of the stealth modes.

The FCC, however, does not “own” the part of the spectrum which “light” comes from so you can hack away there as much as you want. This is why you can find legal laser jammers but no (or very few) legal radar jammers.If you want to test your detector’s LIDAR capabilities just go follow a later model GMC around; their brake lights emit light in the LIDAR frequency range.Then when you figure out that your RADAR/LIDAR detector sucks go get yourself a Valentine 1. ;)Cool project nonetheless.",

RADAR is deadly accurate and in less fraught with the “fiddlys” than LIDAR. With RADAR, an officer can be moving (either way) and check the speed of a suspect vehicle, not so with LIDAR. RADAR units are also much cheaper to purchase and maintain, not too mention they have years of case law behind them. Many judges are inclined to believe the officer in a RADAR case because they know the accuracy is spot on if set up and operated properly.As for the ball toasting, gene-splicing effects, those “experts” are incorrect and this type of litigation is decades old (and was unsuccessful). Just because they operate in the microwave frequency doesn’t mean you can heat up your coffee. The average RADAR unit puts out a bout as much radiation as 30 or so healthy fireflies. The Tritium night sights on the officers’ weapons put off more radiation than the RADAR unit.As for getting out of a ticket, sure, you can retain and atty, who will advise you to have your car calibrated and bring that sheet to court. In court he will ask to see the officer’s calibration sheets for both patrol car and the specific radar unit and tuning forks (used to test the calibration). You can do all this yourself for free (free meaning no atty fees) of course. Easier to just pay the fine. If you are not driving like an idiot, it should be fairly inexpensive; certainly cheaper than atty fees and all the other stuff.",

[Taufeeq] sent in his “
Circle of Light
” bulbdial clock. You may remember when we showed you
Evil Mad Scientist’s version
a while back, and [Taufeeq] did use it as a base but he’s added some of his own little touches. Some of the changes include using a PIC with an
RTC
chip instead of AVR, which allowed him to shrink the board down small enough to fit behind the clock face, rather than on front. He’s even
zipped everything up
conveniently to help you build your own.

R/C Lawnmower

[Johndavid400] built this
incredible looking R/C lawnmower
. After spending some time repairing broken R/C cars, he wanted to move on to something a little more useful and powerful. He decided to build a mower. He’s using a transceiver set from ebay, with an Arduino interpreting the signal and outputting to his custom motor board. In the video after the break, you can see that the mower looks responsive and quick. He does note, however, that he had some glitches early in the process that left him with a runaway mower. We covered a
very similar mower
ages ago that used a wheelchair as the base.

Show us your skills or don’t comment.I’ve been wanting to build one myself, specially since my rear drive mower threw the transmission, but I’m too busy with work and freelance stuff. To the guys who think the arduino is not necessary, check the commercial units. They have a cpu to smooth the steering and attitude of the unit (stay on a straight line when you push forward). This is something the project creator needs to polish in the code, as I can tell from the video and his mention of loss of control in the instructable.I’d probably use a PIC instead and an accelerometer.I’ve never used an arduino, but looks like an interesting platform. The haters make me even more curious, so I’ll probably request one at work for evaluation :P",

"content": "@andrewSince I’m planning a project like this, that’s a very good question. Apart from a range of commercial units that are mostly battery-electric, there are a number of similar builds on the net, all-electric, and petrol-electric. The ones that work are based on the motor/geardrives from wheelchairs and mobility scooters.From a video I’ve seen these seem to be a bit of overkill as the mower was almost too agile.http://members.iinet.net.au/~tnpshow/RCLM/intro.htmI’m thinking of something smaller moved by windscreen wiper motors with more gearing – slower, but lower power requirements.It’s really easy to add stuff, layers of functions and complications, but a hat tip to OP for getting the basics happening. Now he has somewhere to bolt the bumpers, camera, ultrasonic radar, IR grass scanners, big mushroom head emergency stop button … more smarts for more autonomy.One major variant is to mount a car alternator on the mower deck, and you can do away with the big battery. Makes sense if you are going to run an engine. I have something more modest in mind.Observed: skid steering, wheel or track, is simple and inviting, but very power expensive and hard on the machine. Rear wheel drive/steering like this is more practical for a mower, as is the side-by-side config with the drive wheels at the centre with castor steadying, allowing turning on the spot.Simple playback is a problem because of the traction and slip problems on real grass. For autonomy it has to be able to continually re-adjust it’s mental map to the position reality.Hey Guuuys. There is no point in hardware or software imperialism.I’ve done dozens of major projects around almost as many platforms. Every language and platform has its individual stengths and weaknesses. The trick is knowing when NOT to use something as the harder, or perhaps impossible, way to go. Otherwise any system that delivers your answer before you need it is good enough.Processing power is now so cheap that it makes sense in a robotic application like this to use a number of smaller PIC’s to take care of the real-time local grunt such as traction motor control, ultrasonic radar, CCTV image processing; and have something smarter doing the high level thinking.The problem I have is when a processor is used where something more repairable would be better.

The wheels on my push mower are wearing out, so this is the perfect excuse.Note about GPS guidance.

[M]ouse: A PS/2 To C64 Adapter

[svofski] has a friend who is a pixel artist. They really wanted to try out their skills on a c64, but were missing a mouse. The original mouse for the c64 was not only serial, but used a different method of communication than more modern mice. [svofski]
built this adapter to translate the ps/2 data
to something the c64 can use. The writeup describes the build in detail and even has the PCB and source code available for download.

When used with analog devices are used, the 4 directional up, down , left, or right (Pins 1,2,3 and 4 respectively) are used for buttons, in order for pins 5 and 9 to be used analog directional inputs. Inside the computer these 4 analog inputs (aka pins 5 and 9 of both joystick ports) are sent to a 4066 chip which contains 4 analog switches which selectively connects one or the other post to pins 23 and 24 of the SID chip. These are analog inputs into the SID chip. So I looked at the Amiga These 4 analog input existed in the Amiga 1200, and I suspect also in other Amiga’s. In the Amiga 1200 these go to U# which seams to be called the PAULA chip and are labelled as still being Pots X and Y. Pot is short for potentiometer which is the variable resistor inside of paddles and joysticks. There you are incorrect in you assumption. The Amiga’s were built are technically Commodore computers, Amiga’s were built under the Amiga name, but were manufactured by Commodore, so why re-engineer an elegant and working interface. So yes Amiga’s do have a analog inputs on they’re Joystick ports.

The DIY LIL CNC project
is the newest member of the homebrew fabrication scene. This is a three-axis
CNC
mill that can be built by anyone with basic shop skills and about $700 in their pocket. Many of the materials can be acquired from the likes of Home Depot: the basic framework is assembled from Masonite, while other cost-cutting measures include the use of skate bearings and a common Dremel tool for powering the cutting bit. About half of the cost is for the HobbyCNC driver and stepper motor package that runs the show.
The instructions for the DIY LIL CNC are distributed under a
Creative Commons
license, allowing for modification and distribution with few restrictions. They’re well-written and quite thorough, including all patterns and a complete bill of materials with suppliers, part numbers and costs. As documented, the ’bot can produce parts up to 12 x 14 x 2 inches, but the project’s creators offer some suggestions on adapting the design for larger work. It’s not self-replicating like the
RepRap
aims for; you’ll need access to a
laser cutter
for some of the parts. If you can clear that hurdle, this looks like a great introduction to
CNC
production.

I’ve been following the postings on this site, but have often wondered if a homebrew CNC machine could perform this task fairly well (among numerous other tasks).Also, does anyone know of services that provide laser cutting for fairly cheap? If so, what types of drawings does one need to provide to these types of services? I’ve done some basic technical drawings in AutoCAD back in the day, but certainly don’t have these tools available to me now. (Granted, there’s pretty much an open source tool for everything :) )",

And besides, you still don’t get PTH which is a PITA.The cost of the milling parts are expensive, comparable to the cost of sending it out (not domestically though) and just about as fast for jobs that are 0.5 sq.ft double-sided. You waste a significant amount of base material and tool wear getting it to work right, adding to the time and cost.To me, direct print or laser resist-removal (ideally *clad* removal!) seems to be the most practical, affordable for a local group of like-minded makers. One place for the equipment, chemistry set and storage/disposal.One thing that I never hear anyone talk about is the possibility doing PTH at “home”, but I’m not familiar with the process. Are there no feasible, accessible chemical/electroplating processes for this?Really guys, just say “no” to PCB milling, unless you’ve well over $10-20K for equipment, a taste for substantial recurring tool costs and a lot of time/patience.My $0.014 worth.",

The plywood structure can be milled in less than one hour, and complete assembly takes about 2-3 hours.http://fab.cba.mit.edu/classes/MIT/863.09/people/jonathan/We used it for PCB fabbing and also wax mold milling and the results are great, for example we did this Isp programmer with ithttp://www.flickr.com/photos/mellis/4038021210/in/photostream/&&http://www.flickr.com/photos/mellis/4033001478/The precision of the machine is far better than our Modela (using 1/64th endmills).Personnaly, I think that for milling small single sided FR1 copper-clad laminate (phenolic paper) board + SMD components a small machine like the MTM mini is perfect. It takes usually 30 min for a small board (something like the maximum size of eagle free edition) and it is very secure and clean (you can do something else during this time).

While milling only the copper away you mill as less as possible and the overall quality is very good.Higher cost brand mills face same problems too. The spindle selection is paramount if you want as low run-out as possible, again I go for Proxxon IB/E.In my mill I had to make a custom 1/8 bit holder using a spindle from an OOOOOld hard drive (it was of 129MB with bad sector count printed on the label and it hosted 8 plates) and turning a shaft from round stock to accept Dremel attachments.Dremel collets are made from aluminum and they are far from good quality (for pcb milling that is).One thing very gratifying is to have the pcb drilled perfectly, I just swap the bits when the cnc program (mach3) asks for it.Prototyping this way is fast this way, for production of a well designed board I’d say go for TT or outsource.",

Duino Tag

During our daily rounds we stumbled upon
Duino Tag
. Sure it’s not as awesome as a
coil gun
but it really sparked our imagination. First the base: an Arduino is wired up with IR LEDs and placed inside of a plastic pistol. A second Arduino with an IR receiver is scanning for the first Arduinos signal. A ‘shot’ of IR light is ‘fired’ and detected, you get a ‘kill’.
The base is nothing amazing, but it really gives us some ideas and we would like to see it expanded upon. [J44] has already put in a piezo and other LEDs to simulate muzzle flash and other effects. But we like to go further. Start off with multiple pistols and players. Include
GPS
to track players current position, and
wireless
to update each player of another player. A small
wrist watch display
could act much like a UAV. Add some expansions like IR ‘grenades’ and you’ve got a full-out war! What would you like to see?

Mix a cup of mechanical engineering with a dash of drum set and you end up with
Steve, the robotic drummer
. We know that it uses an
MSA-T Midi Decoder
but that’s about the extent of what has been shared. Just from observing the video, we think Steve’s got a few things going for him when compared to
PEART, the robot drummer
we saw back in 2005. Steve features two sticks for each drum and symbol and seems to be quite responsive.
Steve’s great, but we still think
Rick Allen’s
got this thing beat. Although this is a quality build, there’s no replacement for a human that can bang the drum in millions of subtly different way. That isn’t to say we don’t see potential in the hack. Perhaps it’s time to update a classic idea, the robotic orchestra. Don’t know what we mean? Check out 3:58 into the video embedded after the break.

Take a look at the robotic orchestra 3:58 into the video.

This
wort cooler
looks beautiful. No, it’s not for removing warts, it’s part of the brewing process for the nectar of the gods. Even if it wasn’t meant to create alcohol, we would be drawn in by those pretty copper curves.
We’re not surprised at all to see this
remote-controlled bowling ball
. We’ve seen
remote-controlled spheres
several times and this just seems like the logical conclusion. We wish there were some build details though. [via
neatorama
]
When [Anthony Toth] an aircraft enthusiast, decided remodel his garage, he
shot for the sky
. He has recreated the first class cabin of a Pan Am 747 circa the 1970s. It took him nearly 20 years to scavenge the parts and over $50,000 to pull it all together. [via
makezine
]
This
super cheap simple cable tester
caught our eye. There’s nothing complicated here, pretty common sense really. Why didn’t we think of it?
Over the years, Asimo has become a household name. At least in geek households. We’ve seen him go from crazy looking walking microwave prototype, to giant scary space man monster, to the lovable little guy we know now. You can see the
full evolution of Asimo
in this picture series.
Got an old box camera? Want to use it with modern 35mm film? Here’s a guide to
getting it to work
. It mainly just involves making a simple mounting bracket.
We like LEDs a lot, but this is getting ridiculous. This
dress has 24,000 LEDs
. They power it with iPod batteries spread throughout the dress. This cuts down on the bulk and helps distribute the weight.
Coffee cup technology hasn’t changed much in the last bazillion years. We’re pretty sure cave people carved them from stone, and now they’re made from ceramic which really isn’t that different. Some
researchers are changing all that
, and designing a coffee cup that is supposed to regulate its temperature in a new way. This mug is manufactured with internal convection channels and is made from a material known for its temperature regulation called PCM. Interesting, but it will probably cost much more than a simple insulated thermos. [via
neatorama

The reason that real cable testers step through each line individually is so you can tell if you have any pairs mixed up. In other words, if the LEDs on the tester don’t go through 1 to 8 in the proper order, something is wrong. That same cable would appear to be correct through this tester, as it only shows that the lines are connected, not what order they are in.The other problem is that I am rather skeptical as to cost involved. From the looks of it, he got his parts at the Home Depot, and being in there quite a bit I know that the wall box, wall plate, and 2 keystone jacks cost him at least $15. You can buy a proper RJ-45 tester (that goes pair sequences, not just continuity) for $4 – $8 shipped on sites like DealExtreme.",

Instruments As Games – Games As Instruments

Here’s a pair of diametrically opposed hacks. One makes use of a real instrument to play Rock Band, the other makes use of a game controller to play real music.
[Tim] lets us know that his friend figured out how to
play Rock Band 2 on expert level by playing flute
instead of singing. Of course this works because the game is just looking for the correct frequency for scoring. It makes sense that the vocal lines can be offset by an octave and still register correctly. We wouldn’t have thought of this ourselves but now that we’ve seen her success, we will try it (our instrumental skills far out pace our singing talents).
Seeing this sparks a correlation with
Phone Phreaking
, which started with a blind kid singing a tone into the receiver to make the remainder of his long distance call free. This was followed by
Blue Boxes
that allowed people without perfect pitch to play the tones electronically. It would be interesting to see what could have been done with a talented flute player (like
the beat-boxing flutist
) and one of those old phone networks.
On the other side of the coin, we have [Jordan’s] project in which
she creates midi controllers using Wii drums
from Guitar Hero World Tour and Rock Band. The Guitar Hero drums are velocity sensitive, a feature she’s using in her setup. The MIDI data takes into account how hard the drums are struck and the resulting sound reflects that. This particular writeup outlines her use of Osculator for the velocity sensitive system, but you can also check out the tutorial she wrote covering the use of JunXion with the Rock Band controller that
we covered in the past
.
Video for both of these control schemes is included after the page break. We love to see people break the guise of “I’m creating music by playing a video game” and actually use their musical talents in a new and interesting way.

Introducing the
Thingamagoop2
! Remember that
awkward looking box
with two LEDacles sticking out and a bunch of strange buttons and knobs that with some
circuit bending
synthesized different sounds that kept your neighbor up for hours on end? Well now its back! Smaller and one less LEDacle, but jam-packed with more features – like our personal favorite: the ability to program it via Arduino. Check out a video of the ‘music’ after the break.

The Atmel AVR chips reset when RESET is tied to ground, so the reset line shouldn’t be grounded normally. The other two are TX and RX (which tie the AVR to the FTDI chip as well) so all they’re missing is ground which looks like it’s tied to Reset for some reason (ground is 4 pins over from Reset on the front connector). I guess the software on the PC is setting the appropriate FTDI line that pulls Reset to ground.",

The box’s CV could also be used to control other parameters on another instrument (filter cutoff etc.).The end result sounds like shit- (subjective I guess), but hey, no ‘circuit bending’ going on here.",

Raid The Dollar Store For An Illuminated Umbrella
|

"flashlight",
"led",
"umbrella"
] |
Here’s a quick and easy
illuminated umbrella
that [Mikeasaurus] built. How’s this for economical? He found an umbrella that someone left on the bus, and used an LED flashlight and clear poncho from the dollar store for the rest of the parts.
The scavenged LED circuit board is the perfect diameter to fit inside the handle of his umbrella. He removed the middle LED and drilled a hole in the board for the shaft to pass through. Although not well detailed, we gather he managed to shoehorn two CR2032 3v batteries underneath the PCB to power the device. The poncho is wrapped around the shaft to diffuse the light. This is a clever solution as the flexible plastic still allows the telescoping shaft to collapse down to its most compact size.
[Mikasaurus’] umbrella doesn’t
make noise
or
emulate the weather
but it is a clever idea. The low difficulty level and availability of parts makes this a great project to do with the young ones who don’t get included in your more intricate hacks.

Yes, I know it lights up for a while, but it actually has worse efficiency than a normal globe, and that ain’t great.I built such a LED torch (flashlight) a while back after a design by Ian Hickman, and it’s ability to get about a year of frequent use out of a single AA cell by sipping it dry is, well, slightly amazing.

We’re filing this one under “best interface implementation”. This
robot is controlled by finger gestures
on the surface of an iPod Touch. It can walk forward, turn, sidestep, jump, and kick a ball based on the input it receives from your sweaty digits. Unlike vehicles
controlled by an iPhone
(or
by Power Wheels
), this has some potential. Especially considering the inevitable proliferation of
multi-touch devices
in our everyday lives.

I’ll bet you that if you give this to kids and don’t tell them anything they would figure it out pretty quick.@Gdogg (more then rasz) Back to your issue which I think is a separate one. Yes it’s an illusion, but so what? They even mention it in the title it’s an -interface-. An interface between you and the robot. Sure you make motions which it translates into a “walk forward” command, but you could argue the same with a remote control. Pressing one of the sticks forward can make it walk as well. So whats the big deal.And @Ipod/Iphone hatersPlease direct me to the nearest wireless multi-touch display store. I mean come on as soon as somebody finds another device that’s also wireless, has a multitouch display, and is that dirt cheap I would like to know. Do you really want people to put disclaimers on everything.“Hi, guys just made something cool please read my disclaimer first. I used an Iphone in my project, but I don’t like it nor do I think it’s cool. But nobody sells such cheap multi-touch wireless displays. Yeah I don’t want to be cool guys, just want to make something that works. Again not loving Steve Jobs really don’t like him at all etc etc etc”I have an Android myself not an Iphone.

Set Phasers To “blind”

[Directive0]
added a 200mW laser to his Enterprise Phase Pistol
toy. This joins the ranks of
hand-held
laser hacks
that we’ve seen around here lately. His build makes use of the stun and kill settings of the toy to switch between different modes. The built-in 9 volt battery holder is tapped into for power. When set to stun, the stun LED indicator is illuminated and a trigger pull sends current limited electricity to the laser diode. When the kill (or blind) setting is selected, the appropriate LED is illuminated and the trigger sends the full current from the battery to the laser diode. Power regulation is managed by the driver circuit for the laser.
This build preserves the unmodded look of the toy gun. [Directive0’s] inclusion of protective glass should fend off the warnings we usually see in the comments of these types of hacks.

I rarely ask questions of that nature when I’m having fun.I guess the only statement close to an answer would be because I already had both an old Phaser toy and a Laser kicking around and wanted to try my hand at reworking the case and making the basic control circuitry so I could adjust focus and aim safely without having to wear goggles. I wanted to have two settings so I could use it for burning or just play around with different optics and refractors without worrying about stray photons blinding me. I acknowledge that this is not a very safe practice and could lead to potentially dangerous situations. I do not suggest anyone else do this. I have noticed that with a laser of this power just having a “Laser is on” light is handy.If you are looking for a specific purpose for this device beyond “pointing it at things and making them burn”, “seeing what crazy things it does in certain glass objects” or “taking it outside on overcast nights and watching it reflect off of cloud bases” well I’m afraid I just can’t give you one.If your point is that this device is without purpose or a waste of time then you and I are in complete agreement but I still had a lot of fun doing it.",

But I can guarantee you every single kid down at Bluffers park spiking Cessna 150’s and dash 8’s are using off the shelf 5mw greenies they bought from some corner store or mall, and wouldn’t know the first thing about lasers or the safe use of one. You will see no home built laser drivers, no home built laser pistols. These kids DO NOT CARE ABOUT LASERS. I would hazard that anyone who spent more than 5 minutes learning about lasers would realize the stupidity and traceability of that action.I’m not sure if this is a case of “once lasered, twice shy” or “get off my damn lawn, you kids”. But if my little pistol here just by EXISTING and not being used irresponsibly causes you some duress then I apologize. All I can tell you is I am extremely careful when enjoying my laser, show it to only the people I know are responsible enough to handle it, and I do not discharge the laser at anyone or anything with retinas. I always use proper eye protection, but that goes without saying.Beyond that, you’re just going to have to relax and realize that people need to have fun and sometimes that fun is ill-advised. May I suggest that in the future you try to judge peoples actions and intentions don’t just assume someone is a douchy plane spiker, cause that ain’t cool.Peace, Love, and Lasers.Directive0",

[Audin] got a hold of a pressure gauge and decided to
turn it into a clock
. We were under the impression that these types of gauges were filled with oil but he didn’t detail cleaning it up for his purposes. Once he gained access to the guts he replaced them with a stepper motor. The motor connects to an Arduino with the help of a Darlington array for handling the large load. [Audin’s] plans include using a real time clock (on order) and moving to an AVR ATmega8 microprocessor once the prototyping is finished. In the mean time, he has posted
the code used in his current prototype
.
Stay with us past the page break for some video of this in action. He’s got the needle dialed in for very precise movement and has coded a “jitter” effect as well. We’re not sure this would be the most convenient clock, but we’d love to affix it to our kitchen stove for a gnarly looking timer. [Audin] acquired the gauge at his local
Habitat for Humanity ReStore
, a place we’ve used many times to source reclaimed and unused items of all kinds for our projects.

"content": "This gauge didn’t have any oil in it. It was simply a piece of sealed, coiled copper tube whichexpanded slightly when pressurized. The small movement of the end of the coil was amplified by a gear arrangement. Sadly I appear to not have taken any pictures of the original innards. :(I figured the stepper was acceptable to get the project moving along.When I run into another gauge I might try animating it with steam. A small electric boiler and two solenoid valves. If nothing else it would make neat sounds….hhhhiiiiiiiisssssssss. But it wouldn’t be something you could leave running for extended periods. One question I have on this though is what sort of pressure ranges these gauges run over. There isn’t a unit printed on the face of this one. So I’ve no idea how much pressure ’60’ would imply.I like the idea of a kitchen timer. You could do a completely analog one. A button to pressurize the gauge and then a controlled release of pressure (i suppose that would be the hard part) would cause it to count down. You could use co2 cartridges for the pressure supply.",

There could be a buffer tank between the valve and the gauge so you have a known volume of air at a known pressure (as opposed to connecting everything directly with tubing, where you would probably have to figure out the volume of the tubing. With a buffer tank you should be able to just neglect that. With some calibration, you should be able to get good stepped motion and make it tick like a clock.

Optical encoders are nothing new; they can be found in everything from mice to printers. They’re great for allowing DC motors to know their exact position and even current direction. If this is sounding like old hat, it’s because we’ve shown you rotational versions before.
[Chris] uses the same concept, but produced a
linear optical encoder
instead of
rotational
. His setup is much like whats used in non stepper-motor CNC and RepRap mills, allowing ordinary DC motors to know their position within a plane. It’s a quick tutorial, but we liked the detail and it reminded us we need to finish that DC motor based mill thats still a pile of parts in the closet. Check out a video of [Chris’] in action after the break.

When the combination of the two sensors says “white stripe” then you know your location is within a stripe and not just over the end (as the other sensor would report “black stripe”).One could use the analogue nature of the sensor to see if you are only slightly over into white from black but this assumes consistent behaviour on every white/black boundary and all operating environments.Sorry, I went on a bit (I’m wasted on my day job when I could be hacking away on real electronics)",

[Kizo]
repurposed a flatbed scanner to use as an exposure box
for making printed circuit boards. Exposure time is controlled by an AVR ATtiny2313 microcontroller. The device is connected to a separate display board to control four 7-segment displays using one shift register for each. Time is set in ten second increments and once started, switches on the lights with a relay. Once the right exposure time has been reached, the lights are switched off and a piezo speaker is buzzed. There’s no mention of they type of bulbs he’s using but they look like compact fluorescent with tin foil beneath as a reflector.
If these are just CFL bulbs, how will the performance compare to
a light box based around a UV light source
?

(Light from the wrong direction is worse than a slightly longer processing time!)The trick is to get the light distribution very even over the whole surface, and to get the light perpendicular to the surface as much as possible.

DIY Circuit Etching Video Tutorial

Circuit-bending blog GetLoFi has posted the
best tutorial yet on home-made printed circuit boards
using the toner transfer method.
We’ve covered
homebrew PCB
fabrication
techniques
about a
billion
times
before
. What sets this tutorial apart is that it collects many bits of knowledge otherwise scattered all about the web, and then depicts the entire process on video, from initial printing to cut PCB…because
reading about it
versus
seeing it done
are two different things entirely. They give a number of immensely useful tips throughout: choice of materials and where to get them, tools and techniques, and dispelling several myths about these methods (for example, they’re adamant about
not
using acetone
to clean toner from the PCB). Well worth the 30 minutes to watch. If that’s too much and you’ve been stuck on just one part of the process, the tutorial is in three segments.
Trimming finished boards on a paper cutter? Who would’ve guessed?

One way to prevent that from happening is to use a brush like he does.Another method which I have discovered is to use a lot of acetone and wash it off quickly. I put the board on a flat surface, pour a pool of acetone on top of it, and wipe it away quickly with a paper towel. That way the toner remains suspended in the solution and doesn’t [usually] smear on the board.",

If you watch the whole video you see it takes from the afternoon till what seems like the middle of the night to etch the things. The transfer process is, for lack of a better word, ridiculous. Multiple copies on different papers on different machines, then running it through the laminator a half a dozen times (and pray the mask doesn’t shift), cooling it, etc. It is almost like there is a competition to develop the most convoluted way possible to transfer an image to the board.I have never etched a board myself, and things like this just keep me farther away from even attempting it, so maybe I have a fundamental misunderstanding of the process. But couldn’t you do something like put a marker in a CNC machine and have it mask off the lines that way? Then just etch in the acid? I have read about masking with lasers in CNC machines in the past, but my understanding was getting a powerful enough laser was the issue currently.Obviously getting a CNC would be initially more difficult than going to Kinkos, but on large runs like these guys must be doing, it seems like it will pay for itself.",

I use to do this crap with photo paper transfer, and the whole heat transfer and paper removal process took a good hour or two+, and it didn’t work well most of the time anyway. With the toner transfer paper, I only need two passes through the laminator (probably could use just one–just never tried), and about 5 minutes or less for the backing to come off, and one pass with their TRF foil if I’m doing a fine pitch board. I’ve got a good laser printer already, so that saves the trip to kinko’s. Afterwards it just goes into the etch tank, and I can typically get < 1 hour time to produced single sided board before drilling (a lot of my designs require minimal drilling these days since they're mostly SMT). Great stuff for prototyping, and I'd say that there's definitely a sweet spot in production quantity and target cost where doing this is worth it (I think I've 2-3 other online shops using the same pulsar transfer system for the boards they sell)",

The trick seems to be (apart from cleanliness) to put a sheet of paper between the iron and the film, press firmly until the whole PCB is at the same temperature as the iron and then run the board under cold water to encourage separation. The ONLY time I have had boards fail has been when the Iron was too hot.

The toner tends to smear when you iron it which effectively reduces resolution.With exposure/develop/etch we get reproducible results down to 6mil structures amazingly stable. But you gotta know which printer to use. Lasers usually have a problem with coverage and they shear the image a bit. Ink printers are better for 2-sided boards (almost no shearing) and if you print on special foil, you get best results. However, you might have some resolution problem. To obtain reproducible results with 6mil structures you will need at least 1200 DPI.To tin the wireboard theres an interesting method using soldering paste for copper-tubes (already includes solder-flux), thinning it a bit with water and either putting the board into an oven capable of heating up enough (but not too long or the base material could burn) or use a hot air gun. As soon as the paste dries and creates bubbles, the board is tin-coated.You also might heat it until the tin is completely molten but from my experience that’s not advisable for SMD pads cause they might contain too much tin afterwards to be cleanly soldered.",

I can apply a new layer(with a brush) after all parts are in place for protection. The solution shouldn’t need to be very concentrated as this will leave the board sticky.The toner transfer method is cheap and easy, but it has a lot of variables, and it’s eventually up to the user to find the perfect setup.

"Simple Hacks"

Here’s a collection of simple hacks you can do in between larger projects. After the break we’ll look at converting an iPod from hard drive storage to Compact Flash, build an LED desk lamp using LEGO and USB power for charging, and use an Arduino shield to add network control at the touch of a button.
iPod HDD to CF Conversion
[Richard] tipped us off about
converting an iPod from a hard drive to a Compact Flash card
. We actually did this a few years ago. Because we frequently buy broken electronics we had an old iPod 20GB with a broken HDD. Knowing we had seen
one wire-porn type diy adapter
and
reported on another
, a quick search produced a ready-made solution.
[Richard] went the same route by purchasing a CF to 1.8″ IDE adapter and a 32GB Compact Flash card. Just crack open your iPod, unplug the broken HDD, plug in the adapter and CF card, close the case, and go through a normal iPod recovery cycle.Compact Flash is considerably cheaper than solid state hard drives which makes this a cheaper conversion than
a comparable Zune upgrade
.
There you have it, what once was broken is now whole.
LED LEGO Lamp
[chAos]
put together a desk lamp
with parts he had on hand. A broken Bluetooth headset was used for the switch, battery, and USB charging capabilities. From there he built an articulated arm and body out of LEGO. The final step to provide illumination was just a matter of wiring up a white LED. This isn’t the
most beautiful LED lamp build
, but it gets the job done and adds a little “I built this” pride to your desk.
Mute button connected via the network
[Justin] needed a mute button for some speakers at the other end of the room. The music was played by a Mac mini so he built
a mute button that sends commands over a network
. By using an Ethernet shield for an Arduino he’s able to detect a button press and send commands over an XML-RPC server to get some peace and quite around here. The device gets its electricity by using power over Ethernet. The
Ethernet shield is one of our favorite add-ons
, taking on the brunt of the work in getting connected.
Don’t be afraid to
send in hacks
of all difficulty levels. If you’ve got one that’s a bit simpler, we may feature it as part of a group.

Coaster Controlled HTPC
|

"RFIDJ"
] |
These days, HTPCs are becoming more and more common, however controlling the content elegantly can be a painfully annoying problem. Roteno Labs have come up with a wonderful solution they call
the RFiDJ
. Similar to the
RFID phone
we covered earlier, they used a set of picture frame coasters and mounted descriptive pictures as well as unique RFID tags in each one. When a coaster is placed in the sensor area the server begins streaming that particular selection, including local news,
This Week in Tech podcast
, and other specific albums.
Roteno Labs
even managed to include a “shuffle” tag which would play content randomly out of a library. The end result is very well put together, excellently documented, and there is even a working video after the break.

Color Correction Patch For PS3 Eye

[Max] was happy to see that the PlayStation 3 Eye has support in the newer Linux kernels. Having sat in his closet for quite some time, this would give the camera another chance at usefulness. Unfortunately, the driver doesn’t include framerate selection and color correction so he set about writing
a patch to control the color settings
. As you can see above, his success greatly improves the image quality you get from the device.
We get the feeling that the camera peripherals for Sony’s gaming devices seem like a good idea but don’t have much staying power as a realistic gaming interface. With contributions like [Max’s], they can be re-purposed. The PS2 had its own,
the EyeToy, which has long enjoyed driver support for Linux
. The NUI Group does a lot of work with multi-touch and recommends the
PS3 Eye for use with their projects
because they’re inexpensive with high frame rates and decent picture quality.
Great work [Max]. It looks like he’s sent this patch upstream to be considered for incorporation into the kernel’s webcam module.

Server Not As Think As You Drunk It Is

"Case mod",
"server",

[Janos] pulled off a unique case mod by fitting
a computer system inside of a whiskey bottle
. Inside you’ll find a 733MHz processor, 256MB of ram, a 40GB hard drive, and a 60 watt power supply. The specs seem a little light but since this mod is from 2006 we certainly understand. Using
the right server software
this will still keep up with today’s demands.
It sounds like the hardest part was putting holes in the bottle. After a few failed attempts, [Janos] found a professional glass grinder to cut the openings for him.
The whole thing was running a little hot and instead of
filling the bottle with oil
(oh, how we wish he had) he added a second fan in the bottle’s neck and drilled some air intake holes. This brought the temperature under control while preserving the boozy look of this creative enclosure.

Augmented Xylophone

"Arduino Hacks",

"xylophone"

[Ania’s] been working on extending a xylophone in
a project called Multixylophoniomnibus
. She’s fitted a piezo sensor on the bottom of each xylophone key, interfacing it with an Arduino. When a mallet hits a key the corresponding box augments the sound in one of several ways. It looks like she’s prototyped a box that twangs a rubber band, one that uses a solenoid to clap mini cymbals together, one that rattles a glass full of beads, another that vibrates a glass full of water, and yet another that rattles a chain.
It’s nice to see how versatile the xylophone is for
instrument hacking
. Her Flickr set is linked above but we’ve also embedded some prototyping videos after the break.

ArduiNIX: Nixie Shield For Arduino

"ArduiNIX",

"nixie tube",
"shield"

Flock of Butterflies has just published their
third post in a series about the ArduiNIX
, an Arduino shield that drives Nixie tubes.We’ve featured Nixie tube projects such as
a single tube clock
,
free-formed Nixie circuits
, and
tubes in a bottle
. Now the hurdle of handling high voltage tubes while protecting low voltage logic circuitry has been taken care of for you. The shield can be
purchased as a kit
but the Eagle CAD files are also available, allowing you to etch your own circuit board.
Although this is meant for the Arduino there is nothing to keep you from using it as a driver with any microcontroller. The board listens for 5V logic levels to switch the multiplexed display of up to eight tubes. Get your hands on some Nixies and give this a try yourself.

Computer Learns From Tic-tac-toe

"MENACE",
"noughts and crosses",
"probability",
"tic-tac-toe"
] |
MENACE, the Matchbox Educable Noughts And Crosses Engine, is a fancy name for a machine that plays Tic-Tac-Toe. The concept is a product of Professor [Donald Mitchie]’s work in the 1960’s and was featured as an example in
the “A New THEORY of AWESOMENESS and MIRACLES” talk
given at this year’s
UK games conference
.
[James Bridle] built this fascinating example of how a computational system can learn from its successes and failures. Each box corresponds to one of 304 different board layouts. The operator uses an index sheet to locate the box that corresponds to the current state, shakes the box, then looks to see which bean has randomly fallen into a partition in the box. The color/type of bean corresponds to a space that the machine has “chosen” for that move. If MENACE won the game a bead matching the move that was played would be added to each box used. If MENACE lost, a bead would be removed from each box used. This way the machine cannot make the exact same mistakes twice, and is more likely to repeat successful solutions.
[James] notes that he couldn’t find any evidence of this machine actually being built before. It is possible that this was always a theoretical device but now we’ve seen an actual build. We consider this to be a computer because it is calculating moves based on probability of success but what do you think? If you’re thirsting for more pictures there’s plenty to see in the
Flickr set he’s posted

If the machine is capable of computation, I’m not sure what that computation would be, since that first function is not computable (and of high entropy)! The second function is just memory.Thanks for the reply, I enjoyed thinking about this! (Also I still use a slide rule.)",

Ping-pong Launcher Your Wife Can’t Know About

Sometime the projects you see at the local hacker space are better left a secret when you return home for the evening. Case in point,
this ping-pong ball launcher that can put holes in a sheet of OSB
. The projectile is made more lethal because the ball has been injected with water to dramatically increase the density. Compressed air is used to propel it from the 14 round magazine with devastating effect.
We’ve embedded a video of the gun being fired after the break. The creator, [Ron Kessinger], demonstrated this at a
Denver hacker space called Club Workshop
. We’re hoping there’s no plans for
turret automation
because this thing’s dangerous! Either way, the significant other who usually watches out for our safety would never approve.

Medium Format Camera, From Scratch

[
"camera",
"film",
"traditional media"
] |
[Peter Johansson] has taken it upon himself to
build a medium format camera
, from scratch. We know this is a shock to some of you, but this camera uses traditional medium. There is no sensor. He will be loading it with (gasps) film. He bought the lenses pre made, but everything else is being constructed by himself. Probably the most notable parts are the aperture and the shutter. The project is about 80% complete right now. We can’t wait to see it finished.

[Aki] wanted to do some stationary cycling to get in shape. Unfortunately, his stationary cycle is located in his garage which doesn’t supply much inspiration or amusement. His solution was to
build a VR rig
so that he could ride around inside google street view. He has rigged a simple sensor to his wheel to determine his speed and he’s using a vuzix VR 920 as a display and orientation sensor. While he notes that it isn’t perfect, or even reliable, we think it is pretty cool. He can go sight-seeing, while getting in shape from his own garage. We have to wonder if he gets a headache after a while though.

I did think of using an old optical mouse on the inner rim but I dont have one handy and most HID devices cause events that may have other effects on the computer. The other reason for the Arduino was the high-speed polling was performed there and by using blocking IO on the serial port could be used to minimize the impact on the laptop’s cpu load.

I don’t know what your specific case is but… if you’re in windows, and have the vuzix vr920 and an nvidia card, it seems there’s some really nice drivers there that even allow you to send different images to each display – full stereo vision! (BTW: as the person who put this project together, I thought that a few people at hackaday had seen this and thought it was a neat project. I was tickled, truthfully said :)@Evan: You’re totally right – This was totally intended for the fall/winter season.*sigh* Just going to say this since it’s easy to trash this sort of thing:In the summer I was doing real road riding that totaled 200km a week. I love this form of transportation: it’s at your own schedule, don’t have to fight with transit, no guilt and it’s fast.For some time leading into the fall, I was using both my main bike for commutes and my wife’s bike on the trainer for spinning, which helped me keep a higher revolution rate for extended periods on flat stretches. NB. I have problems walking after using the trainer, it’s a proper workout. It also helped, I could tell that there was an improvement in my cruising speed.Weather’s not so pleasant now with it raining most of the time and dark. I also have to change clothing after every ride and my shoes are soaked through after the first ride. I keep an extra pair of shoes at the office but have to return to the yucky wet pair the ride home. Round trip is 2 hours that takes up times of prime productivity for me. I’d rather ride at around 9 and burn myself out for the evening.If the researchers are correct, I don’t need to go hard for a length of time, short periods of activity that add to a similar amount of time will have a similar beneficial effect for the body.So this project helps me take away these excuses for not going out when it’s too annoying to do so. It also has a really cool educational component. I’m still getting into shape but if I travel through the continent with this thing, it gives me not only a goal but an appreciation for how wide and varied this continent is. Think of it: I will have personally turned that wheel over 5000 kms at about 2meters per revolution and spent the time looking at what every state along the way has to offer for view and ecology. All from the road, of course, but the south-western portions of BC are a rainforest with tall cedars and dense underbrush, you can see that from the roads, once I get out to the prairies or desert, it changes.I’ll go back to riding on the street when spring comes back and it’s not such a major undertaking.@therian: I do wear a helmet every time I ride here, it’s the law. Police hand out tickets to those that don’t: don’t believe me? Search the Velo-Love Vancouver’s mailing list. I also stop at red lights and wear a bright yellow jacket and look like a Christmas tree. All this, yet I’ve been rear ended by someone impatient to drop their kids off at their school, cost me 300$ to repair. Those didn’t stop me, but the hassle of the elements did. This way, I can easily make up my 1-1.5 hours of exercise a day in several segments of any duration at my convenience.I think we travel different, I go to meet new people and get a feeling for how the locals live. I really enjoy having a go at understanding how other people’s cultures and value systems manifest.",

Single-wing Flight Based On Maple Seed Aerodynamics

The
Samara Micro-Air-Vehicle
is a product of over three years of work at the University of Maryland’s Aerospace Engineering Autonomous Vehicle Laboratory. The Samara is an applicant in the
DARPA nano air vehicle program
. Unlike the
ornithopter we saw in July
, this vehicle uses only one wing for flight. A small propeller on a rod mounted perpendicular to the wing provides rotation. The pitch of the wing is changed to climb, descend, or hover.
You can see a video of the flight tests after the break. The sound the Samara makes reminds us of classic alien invasion movies and the use of
Verdi’s Requiem
for the background music during flight tests (2:43) seems quite fitting. At about 5:45 there is some on board video footage that is just a blur of the room spinning by. This would be much more useful if a few frames per second were snapped at exactly the same point in the vehicles rotation.

You only need one motor with a really course speed control, a single servo, some foam, and a microcontroller (cue ArduinoRAGE). Add an accelerometer and gyro module to measure spin rate and current craft angle, and the control system is a simple loop of code polled several times per rotation.“You know… that joke got old after the first time you said it, and now it appears in every single article…. ”Joke?

If there is greater efficiency here, perhaps two counter rotating rotors with payload between would be effective — like the heavy lift helicopters that have been in use for decades.",

Primarily it was built because DARPA is funding a nano-scale flight platform, for whatever reason.Because it’s DARPA, we can make a guess or two. Maybe they want a small reconnaissance platform that has the same radar profile as a bird. Maybe they have to be light and small enough for a single recon soldier to carry several. Maybe they have to land uncontrolled, but quietly. Maybe they have to be silent at 50 meters or less.Since DARPA is a research organization, maybe they didn’t have an exact original plan, but a few ideas of what a nano-scale flier would be capable of. And after they see what gets built, they adapt their plans to use its unique features.After seeing this video, I’m guessing they’ll formulate a usage scenario specific to the device. I imagine something like this:1. Fly them at a silent running altitude over a specific target (maybe 200 meters.)2. Cut power and allow them to drop silently into an enemy camp.3. Allow them to spin and photograph all the way down.4. Establish the number and location of hostiles and civilians.5. Send in the Predators or the Rangers or the Seals or the mortar shells.",

[Moris_zen] built a
device to accurately measure the capacity of batteries
. He needed to have an accurate measurement for the batteries he uses in a RC airplane. Knowing the discharge time allows him to fly the friendly skies while avoiding crashes from lost communications.
He based the tester around the Arduino platform. Instead of using a pre-built Arduino board he referenced the
open source schematics
and built the device from components to fit his needs. His solution automatically detects the battery type (Lithium-Ion, Nickel Metal Hydride, etc) based on voltage when the battery is added to the circuit. It then uses a 2.2 Ohm resistor and ADC measurements to take the battery through a discharge cycle. A character display shows status information with the ability to track discharge information using a computer to graph the data.
Apart from flashing an LED this was his first Arduino project. It’s a great use of the platform and much more automatic than
other solutions we’ve covered
.

The
EyeWriter is an open source eye tracking
initiative. This is the mature version of the
KanEye project
we covered in April. Collaboratively developed by
Free Art and Technology (FAT)
,
OpenFrameworks
, and the
Graffiti Research Lab
, they seek to aid a friend of theirs who suffers from the degenerative muscle disease ALS.
They’ve come a long way since we last looked in on the progress. The hardware used is pretty much the same: a set of sunglasses sans lenses with the CCD from a Sony PlayStation 3 Eye mounted in front of one eye. IR LEDs surround the CCD and point at the eye to increase the contrast between pupil and the rest of the eye. The major improvement comes with the software. Eye tracking appears to be extremely precise and they’ve written a custom drawing program to take advantage of their interface. Check in on
their developer page
for source code and a video walk-through of the software.
After the break you can see video of [Tempt1] using the system to create some tags. We’re thankful for the success this project has seen as this guy can do a lot better with his eye than we can with our hands.

Remotely Control Your Crappy Car (dangerously)
|

Here’s one that brings back that giddy feeling we got when the original episodes of thebroken were posted all those years ago. The lunatics over at Waterloo Labs have
altered a beat-up Oldsmobile for remote control
via laptop, iPhone, and…. wait for it…
Power Wheels
.
Brake and gas pedals are actuated using a wrench connected to a motor bolted to the floorboards of the car. The steering wheel has been replaced with a gear and connected to a motor using a motorcycle chain. Much like
the van we saw last month
, an iPhone app has been written to wirelessly control the car of doom. This leads to some car surfing and
ghost riding the whip
in the video after the break.
To our delight, they’ve also implement the most unorthodox automotive interface yet, Power Wheels. A chain has been added to measure the orientation of the toy steering wheel, and an optical encoder is used to measure the speed of the tiny electric vehicle. It looks like it doesn’t do the best job of translating to a full size vehicle, but it maxes out their style points.

As for steering the best I could come up with is to simply hide a gear driven motor in the dash attached to the column, but I’m not so sure… depending on the car you might be able to fit such an apparatus in the engine-bay even.that just leaves the transmission, they have fully electronically controlled automatics, but no cheap car has those… the best bet might be to find one with an external shift linkage and simply throw an actuator under the car to get it working.",

AEVIT by EMC is one of those ‘adaptave mobility control’ devices for disabled and wheelchair bound to drive. In essence there’s a computer screen with the main controls (start, park, drive, etc) and a control ‘panel’ in your lap or mounted in the vehicle for gas/brake and steering.DARPA teams just tap into the AEVIT/EMC system for their control. And the nice thing is it’s fairly unobtrusive. There’s a giant black unit under the steering wheel to ‘set’ the system and align the wheel with the servos and such, and then down by the pedals is another box with the actuators for brake and gas. A regular person can also use the system – just don’t “enable” it when the car’s turned on and it won’t work.",

With my “powers wheels” the power was me pedaling as fast as I could. Dead man’s switches would be a good idea, as would be a big rig like “maxi brake” concoction that would apply the brakes, while cutting the ignition as a deadman’s switch is tripped. Several years ago my dad was putting togeter an oil well servicing rig. The truck’s throttle had to be controlled from 3 differant locations outide the cab throttle. In the old days they use air to to operate a ccyliner under the hood. The throttle by wire on the new computer controlled diesels posed a kink to work out. I suggested a thoratl position sensor at each location, using a switch to select the one needed. Bt those sensors where expensive, and the ended up using an air cylinder under the dash to operate the thottle in the cab. Thinking about it, there is a lot of stuff used in the oil patch that could be useful in robotic control. I think the pot segment in the video was about getting someone’s attractive gal on tape. Mike *I* approve of this post.",

Homopolar Motor

Slow day at the office? Here’s a trick that’ll make your coworkers smile. Dangerously Fun has
a guide to build a homopolar motor
from a battery, copper wire, and magnet. A homopolor motor doesn’t rely on electromagnets in an armature changing their polarity to force a rotation movement compared to stationary magnets. Instead, they use an electrical current’s orientation to a magnetic field to provide a repulsive or rotational force. In this implementation, the current moves through a loops of copper wire from one pole of a battery to the other. A rare-earth magnet on one pole of the battery provides the magnetic field.
After the break we’ve embedded video of this simple example as well as a few more complex homopolar examples such as a five speed version. The motor in action certainly brings a smile to our faces and places this firmly in the
useless machines
family of hacks.

Oops, this next one’s NOT a homopolar motor. Thanks Fallen.

Using the Lorentz force you see that the bottom of the ring is pushed away from the camera, while the top of the ring is pulled towards the camera. This force continues as the ring begins to rotate.",

Here’s further proof that you should understand what it is you’re doing when you go to hack your handheld. Jailbreaking an iPhone has been made quite easy to the point that a lot of folks do it without reading any of the accompanying documentation. Those who didn’t heed the warning to change the default SSH password on a Jailbroken phone might get a bit of a surprise. A
worm has been unleashed that finds Jailbroken iPhones
and changes the background image to a picture of [Rick Astley]. That’s right, they’ve been
Rickrolled
.
It’s a clever little devil that propagates by grabbing the IP address of the iPhone it is currently on, then testing all of the IP address in that family to find other devices using the default password. Luckily this worm’s activities are not what we’d call malicious. It doesn’t format the root or create a cell based bot-net (that we know of). This would be akin to the antics of
searching Google for unprotected installations of MythWeb
and setting some poor schmuck’s MythTV to record every infomercial ever. The point is, this could have been a lot worse, but the attack is predicated on stupidity. In our digital age, why are people leaving default passwords in place?

AWE is an interesting project
, where your office wall is a helpful robot. That’s the goal anyway. The wall is articulated and can reconfigure its shape to fit your needs. You can see in their video that they have come up with several specific uses for AWE at different positions. We want to like AWE, we see that there is potential there. The video hasn’t won us over, there just wasn’t enough added benefit over a simple setup like a projector mount. We think the real benefit just isn’t as obvious. When we saw the girl stand up, and the wall back away intuitively, our attention was regained. What potential uses do you guys see?

Bike Brake Light Senses You Slowing Down

Group riding can be a bit dangerous if the pace is fast and riders don’t notice a slowing in the front of the pack. [WyoJustin]
designed a brake light system
for cyclists to try and remedy this issue. LEDs are mounted in the end caps of the handlebars on a road bike. When an accelerometer senses the bike slowing down the LEDs light up, warning those behind you that you’re slowing down.
The system is made to be portable, as a lot of serious riders have multiple bikes. To make this happen, all of the electronics are housed in the handlebar tubing for easy transfer. This includes an accelerometer with built in voltage regulator, an Arduino to control everything, and a battery. Take a look at the brake lights in action after the break.
Most of the
bike lights we see are for the front
of the machine, but this backward-facing package is a clean and easy solution we can get behind (safely).

This is a good concept that could use more development for sure but I think some are overthinking this.Example: A pack starts up a hill…there is a point where the leader starts to slow down while the rest of the group is still on level ground …could they anticipate him slowing down..sure…does this remind them to think about that? Yes it does.Could this be underseat mounted…or even a vest mounted unit…maybe..with some work. Maybe make the lights yellow and have them strobe faster as the deceleration increases…add switches to the brake levers (but promise not to “ride” the levers)..and have even more info for the rider behind you to process.The fine details of you are going downhill..pulling away…hit a bump…jiggle the brakes…have different handlebars…ride only at the back. Who cares. This is a prototype. It tries to solve a very real problem for those who ride in tight groups. It could be refined.Oh yeah…the simple switch idea has more problems than some of you have thought about…mercury, reed or otherwise.Ain’t it cool that people can get worked up about something like this though?",

[Hailrazer]
built a handheld GameCube
so he could take his gaming with him. The final product is quite nice, providing a large display and about 3 hours of play time on the lithium polymer batteries.
Starting with the case from a Kidz Delight Datamax game, he used
Bondo
ABS cement and plastic bumper filler to alter the case but still provide a professional look. The display is a five-inch PlayStation One LCD Screen from which he also incorporated the speakers. At least four controllers were cannibalized for use as the buttons, sticks, triggers, and directional pad. Our favorite feature is the totally exposed optical head mounted on the back.
We’ve embedded video as well as a picture of the optical drive after the break. This goes so far beyond just making the
GameCube an all-in-one system
. If you like this build, check out the Nintendo 64 and Dreamcast mods on
[Hailrazer’s] YouTube channel

"prototype"
] |
Our friend [Garrett Mace] from macetech has
finished a prototype
of a new shield which allows the Arduino (or any other microcontroller with
I2C
) to add 64 digital I/O pins using only 2 of the analog pins. Currently he only has a few pre-production boards, and rather than selling them he is throwing a contest to win them. The contest is looking for people who have a specific project in mind that could use the centipede, and on Friday November 13th he will pick his favorite two. To submit an idea, just head over the Arduino forums and post an idea complete with details and relevant schematics, etc.
We will be sure to follow up with the winners of the contest, as well as let you all know when the Centipede Shield makes it into production.

Maybe we’re just imagining things, but it seems to us like brainwave control is the latest trend in toys. Similar to Uncle Milton’s Force Trainer, Mattel has recently released the MindFlex, a game that involves moving a plastic ball up and down through an obstacle course that you control using your brainwaves. Naturally when [Alpha] saw this, he decided to
take it apart
and document what he found. After disassembling both the headset and the base, he found that most of the chips were covered in black resin making them unidentifiable. However, he was able to find identify one chip, the NeuroSky TGAT1-L64 D498Q-010 0924. Judging by the name alone, we would guess that this is the chip that makes the brainwave control possible. While there’s no mention as to whether you’ll be able to interface with this like you can with the
Force Trainer
, we’re sure that it’s only a matter of time before someone figures out how to use this to control more than just a floating plastic ball.

So every time you wanted to change a song on your player you would have to sit still for a few seconds and concentrate on one thing.It would be a cool little project and a neat novelty, but there aren’t many realistic situations where that would be useful. For example, I am generally sitting at the computer working on something when I am listening to music. I wouldn’t want my song changing every time I think about why a function isn’t working the way I intended.Though I imagine there are some interesting applications for a device that reacts to concentration or relative stress level. In fact, a few nights ago I was thinking of a way to use one of these to build a meditation trainer. Punish the user with something annoying (loud noise, electric shock, whatever) if their concentration deviates for too long.",

The headset starts to get uncomfortable after a while with the metal sensor that must be placed above your left eye, but its something I have gotten used to. I would have to say that I don’t believe it relies on any facial expressions, or any kind of blood pressure measurement. It took me about 5 minutes to really get the hang of it. I laid down in the floor with the headset on and the game in front of me. I turned on the system and selected the freestyle option. I relaxed while trying to clear my head and the ball dropped as the fan completely stopped. The moment I started concentrating, the fan turned on, and the harder I concentrated the higher the ball went up. Then once I started thinking about something else to take my mind off of the ball, it stopped again. I repeated this over and over. I have even tried this with my eyes open and closed, and still got the same result. With everything I tried, the only thing I could not rule out, was the fact that it “truly was” reading my brainwave activity. Some people say that it has a pre-programed routine, which isn’t true, because I tried clearing my head for almost 2 minutes, and it stayed still. It always responded as soon as I “randomly” concentrated, with almost pin point accuracy. So either I have telekinesis, (Which is very doubtful) Or the game actually does measures your brainwave activity with a true EEG headset, (Technology that has been around for a while) which is probably the most accurate statement. This game is not a fake nor a gimmick. (And no I don’t work for the company.) I just think that all of those who can’t believe something like this can truly do what it says, are the same ones who won’t accept that technology has truly advanced this far to make things like this possible. Heck, being in the military, I have seen cutting edge technology not available, nor known to the public as of today, that I didn’t even think was possible, until I saw it with my own eyes, and knew and understood the science behind it.",

What do gangs, territories, cities, and glowing blue balls have in common? No, not that one drunken night you can’t seem to remember, rather a new location aware game called
Urban Defender
.
The
concept
behind the game is simple. A player hold a ball that knows its current location and can notify you if needed via LEDs and a speaker of changes in its environment. He or she then runs around the city until the ball tells them of an unclaimed or enemy territory. Bounce the ball against a building and that territory is now claimed.
The ball itself is a
prototype
combination of an Arduino, Accelerometer, vibration motor, LEDs, XBee, batteries, and wire all packed inside of an industrial rubber gym ball. Unfortunately after testing the Urban Defender team found the GPS and a few other components would need to be kept outside of the ball and on the player.
Finally, a project that warrants the use of an Arduino. Anyone up for a game?

Servoelectric Guitar Is A Keytar With Strings
|
Mike Szczys
|
[
"Arduino Hacks",
"Misc Hacks"
] |
[
"arduino",
"fret",
"guitar",
"servo",
"servoelectric"
] |
[Keith Baxter] has undertaken something of a ‘Mount Everest’ of guitar modifications. He’s
developing a Servoelectric guitar
that trades frets for a keypad. It is still a guitar in the sense that it has a body, strings, and pickups to sense the strings vibrations and pass them to an amplifier. The left hand, which traditionally would shorten the strings as needed by pressing them against
a fret
, now changes string pitch using a keypad. This is an interesting fusion between traditional guitar and 80’s phenomenon, the
keytar
.
Each string is connected to a different servo motor. When a key on the keypad is pressed, the corresponding servo adjusts the tension of that string, bringing it in tune at the new pitch. His original design involved a lot of custom circuitry but he’s
evolved the project to include an Arduino controller
. This second generation both simplifies the control circuitry and improves upon it.
We’ve embedded some video after the break. In the first example you can see the strings adjusting for each new pitch. In the second, take a look behind the guitarist… what do you think he’s got planned for those
giant
capacitors?

Horrible thing to play but ok for note entry into a sequencer.This is more like the Transperformance or the Gibson Robot however they use it only for tuning not for actual note selection. Great for switching quickly between different tunings thereby eliminating the need for multiple guitars on stage (or bad players who can’t tell when their instrument is drifting out of tune :) )",

Physical Email Notification

One day computers will exist in every part of our lives. You’ll be standing in the shower, lathering up when Chantal, your holographic computer controlled AI partner, informs you in a cool voice you have a new email. How splendid, it must be the office letting you know there is no work today! “Anything else?” You ask; “Negative” her electronically synthesized voice responds.
Over at TINYenormous
they’ve made this dream
come true – minus the holographic computer controlled AI partner bit. Rather its simply a physical email notification system consisting of an LED and Arduino with some python code. We like the concept but prefer our
Google Desktop
with
Gmail
setup instead. Perhaps by using a small wireless server and rechargeable batteries, it could make a great dinner table centerpiece notifying you of the latest email. How simple, or how complicated would you make a setup?
[Thanks Madmaze]
[Update]
Rob created a very nice
USB version
.
Dan made a
wireless version
from
XBee modules
and includes an LCD.
J4mie is the
original inspiration
for the project.
Have your own
notification system
? Tell us in the comments, And we’ll place it here!

You could just as easily jam the pins of the LED in pins 2 and 18 of a parallel port and make your software output to that. There is no reason an arduino is required to light a single LED.

[Andrew] built a light box for an exhibition last year that displayed different colors statically. After showing it off, it went unchanged but future improvements remained in the back of his mind. Recently, he pulled it out again and
hacked together a controller to drive the colors individually
.
He’s actually reusing some of the hardware he built for a different project. At its core is a PIC 16F628 that actuates the lights using relays. In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different patterns. This is a nice start to making the piece more interactive and we can image adding
web-controlled color changes
, or perhaps some
Daft Punk inspired functionality
.

Didgeridoo Modded To Include Electronic Manipulation

] |
It’s not a bazooka, but this altered instrument makes it look like the player is toking off of some type of weapon. [Kyle] wanted to take the already mysterious
sounds produced by a didgeridoo then capture and alter them electronically
.
The physical build of this project is nothing short of beautiful. He’s mounted several curved control boards to the outside of the instrument. The controls feature six push buttons, five toggle switches, and six potentiometers that interface with an Arduino. The sound is picked up by the device then sent along with the switch settings to a computer via Bluetooth. The computer then works its magic to create the wicked audio effects heard in the video after the break.
His article, linked above, includes several diagrams detailing the synthesis process. They’re a little beyond our understanding but if you know what’s going on, please share your insight in the comments.

Starting a new robotics project and want to find the perfect servo for the job? It can be a real pain in butt sometimes. This is where
ServoDatabase.com
comes in. They’re compiling specifications and reviews on servos. We love seeing these databases pop up. Remember the
online chip reference
? You simply can not have too much reference material.

Ever sat down from a long day of hacking and thought to yourself “I wish there was a cool video game out there made just for me. Better yet, made
by
me!” Today is your lucky day with the
release
of UDK –
Unreal Development Kit
.
In days of old, the only solution to satisfying your game creation desires was a cheap
game making kit
, or adding to the millions of
Source mods
. Epic has changed tables by now allowing anyone to use their engine (non-commercially of course) to create the game of their dreams; who knows, maybe even the next Unreal Tournament.
UDK is currently limited to PC, but plans are in the process for PS3 and Xbox360 development. For those who cant wait, we suggest checking out
XNA
. Whatever tools you use, ever made a cool game? Tell us in the comments!
[Thanks Kinigit]

"content": "The reason indy developers shouldn’t use most of the mentioned open source engines is because they want a high level interface to work with so they can actually accomplish their goals productively.You use the id engine for example you’ll end up writing thousands of lines of code just for a single character control. You also have to handle your own data types and do garbage cleanup. You might as well write from scratch.With engines like Leadwerks and propriety licensed engines from major studios everything is highly abstracted while maintaining flexibility, and that’s how development has evolved and should be. It’s counter-productive to back-step with low level API code.On that same note though none of the engines have things like collision morphing(the algorithm for meshes you use to emulate damage). So if you want bouncing boobs or car damage you’ll have to do it on your own with a state machine and physics engine.This is just engine discussion though. The main problem is content development. A highly skilled modeler takes on average a week to do a single model because of many reasons such as poly reduction, texturing etc..Non-Active objects are simple with the exception of quality texturing. Zbrush is about the only practical solution for that and they micro manage all the aspects of the interface like blender and 3d max do so it becomes a headache to work with.MakeHuman is about the only software I feel has evolved for this problem, and their roadmap indicates the game dev features wont show for years, and most of the CG community want that project dead because it threatens job security..never-mind the blatant innovation is presents.Also for noobs: Literally the only difference between a 3D game developed in 1999, and a ‘next gen’ one on the PS3/x360/PC is physics, and normal maps. The reflections and such are just new shaders.",

Many professionally titles look fantastic, but they are riddled with bugs, and the game play is totally linear… and boring. That’s the best you will see, despite publishers pour a ton of money into these things.The issues with bugs are the worst. Some games can’t be played for more than 5 minutes without the damn thing crashing. Games have become too complex and the project deadlines too stringent. The end result you get is a game that needs 10 patches for it to be playable.I guess using an existing game engine has the advantage that some issues have been ironed out by the licensor.

You wouldn’t find these in a ’99 era engine.

While browsing the web for new and interesting hacks to show you guys, we run across all kinds of interesting stuff. Often, we would love to share them with you, and get your thoughts, but they just simply don’t have enough information or aren’t hacks at all. This is where HackaDay Links come in. Occasionally we’ll gather up some interesting stuff and post it all at once. These probably won’t be hacks, so if you’re not into seeing other interesting stuff, just wait for the next post.
We used to do these posts from
time
to
time
, and we’ve decided to start again. Without further adieu, here are the links:
1.Medgadget has a
pretty cool crutch system
which uses your upper leg for support instead of your arm. Seems like a better way of building support for
digitigrade legs
to us.
2.
VR pods
sure are looking funny now days. Seems like you could do this on your own pretty easy with some
simple dome projection
.
3.We were unaware of The Gadget Show, till we saw
this post
on DVICE. For those that don’t want to sit through it all, they do two projects. One is a wearable computer jacket with a projector built into the sleeve, the other is a set of iPod controls built into some horribly gaudy high heels. We shouldn’t judge the fashion though, they probably know fashion better than us.
4.These
massive robotic arms
have been all over the net for the past few weeks. The video is sort of neat, with cool cgi effects, but all he does is wave them around somewhat lethargically. We do hope to see something more soon.
5.
Princess Leia, sunbathing
. We had to share. Thank us later.
6.You could
win [Ben Heck]’s PS3 laptop
. Unfortunately you have to spend a bunch of money at
the score
. Just in case you’re curious, they value it at $7500

They also cover a lot of innovative new developments, incl visits to tech labs in other countries.They also do a lot of web content incl videos, heres the link –http://fwd.five.tv/gadget-showI dont know if anybody outside the UK can access the videos.

Knock Detecting Lock

[youtube=http://www.youtube.com/watch?v=zE5PGeh2K9k]
[Steve] shows us his version of the
knock detecting lock system
. The idea is pretty simple, knock in a certain pattern and the door unlocks. We’ve
seen it
before
several times
. This solution is somewhat cleaner than the others, not only in physical design, but also in how you reprogram it. Simply push the reprogram button and enter your new knock. We’re a bit surprised that the suction cups actually hold it on the door. Maybe it’s just us, but we can never seem to get those things to hold very well. There are lots of great pictures as well as the source code available on his site.

Each physical item used could allow for multiple parties with personal separate patterns to open. Bluetooth or other radio comm could also allow pattern creation and programming on one’s phone where the door could receive the pattern you tapped onto phone touch screen just before knocking on door.Air or light gaps under door or even eye hole viewer could allow for light or shadow additions to the knock combination by using light detection sensors so only covering eye hole during part of the knock pattern but not during other parts of the knock. Flashlight/laser pointer could add light instead of using shadow detection for use in unsteady lighting conditions where light is part of the combination.For the guest access allowances or maybe kids’ bedroom doors, my thoughts drift to a dance pad controller for some reason flopped under the door to make the user move a little un-naturally on the pad buttons for entry with the knock patterns.",

[Computergeek] made an
Arduino Shield in order to use it as an Apple remote
. We like the construction technique that he used; taking perf-board and soldering the circuit and using stripped wire to interface with the pin sockets on the Arduino. He’s written the code needed to function as an Apple Remote but this shield has a lot more potential. This is an excellent opportunity to delve into the different IR protocols out there and create a universal remote for
all of your random devices
. We’d also want to give it a try as a
TV-B-Gone
.
The parts are easy to find or salvage without putting in an order. We’re not certain about his design, he should probably have invited a resistor to the party the two IR LEDs are having.

Is the need for current drive *really* that hard to understand?I have examples of LED torches (flashlights) that depend entirely on the bulk resistance of the diodes in parallel and internal resistance of the battery in series – utterly bloody horrible “design”. Some LED’s do expire, and they make very poor use of the batteries. Yes, even manufacturers are getting away with such abominations, but they *are* abominations, not examples to emulate.Adding a transistor stage will allow more current to be switched, but current setting resistors then become mandatory. IR LED’s in particular have the lowest cut-in voltage at 1.2 volts, and their V/I curve then rises almost vertically with a slope of amps per volt!See;http://www.electronics-tutorials.ws/diode/diode12.gifI don’t think a “reflector” is actually going to help much because most of the light is already being lensed into about a 30 degree forward cone. What does work is a bit more lensing to concentrate the energy into a narrower beam.",

SSD Upgrade For 24″ IMac

"ssd"
] |
The hard drive in [Jason’s] 24″ iMac was on the blink. He decided that instead of just swapping out the bad drive for a traditional unit he would
upgrade to a solid state drive
. Tearing apart high-end hardware like this can be a bit nerve-racking but luckily the drive is mounted right behind the screen so he didn’t have to take everything apart.
The SSD he picked up was 2.5″ but the mounting hardware in the iMac is only setup for 3.5″ form factors. We would have used a bit of hackery to make it work but [Jason] went with an adapter kit. Uh-oh, once installed there was no problem with the mounting but the SATA cable didn’t reach far enough to plug it in. The cable snaked around under the motherboard and would have been a lot of work to swap for a longer one. He ended up removing all of the mounting screws except for one coercing the drive close enough for the connection.
It worked for him and it can for you as well. If you do this make sure to devise your own mounting scheme so that you don’t hit the same snag.
