True randomness can be hard to come by in the digital world. [Andy Green] is making it easier to
get true entropy by using this random USB dongle
. The Whirlygig uses a
CPDL
to gather data from a set of of oscillators. The oscillators have a constantly fluctuating frequency due to temperature changes; if they run faster they generate more heat which in turn slows them down. This, along with the variable latency associated with polling a USB device, gives great depth of randomness. The device is detected and mounted under ‘/dev/hw_random’ and can then be fed into ‘/dev/random’ using the
rng-tools
package. [Andy’s] done a lot of testing, both on
the hardware
, and on the
quality of randomness
. We didn’t see an option to order this but he’s got
hardware
and
firmware
repositories so that you can throw one together yourself.

This device is lovingly called the SPINmaster. [Linux-works] built it to
spin up multiple hard drives before the motherboard starts up
. It detects the power-up from the PSU and uses a relay to hold the motherboard in reset, indicated by the red LED. Each of four relays then spins up a hard drive and illuminates the green LED when ready. Once all green lights come on the reset relay shuts off and the bios starts up. This type of staggered startup takes a lot of the load off of an under-powered PSU. He’s
posted firmware
and there’s
a schematic
available too. We took a look at his video but there’s not much to see as it’s just the inside of the machine while it boots up.

I have a popcorn hour media streamer and even that thing, with NO drives on it, blows its own PSU. adding a drive would only make things worse, I think.there’s an intel NAS ‘suitcase’ box that also has had some power supply issues reported by users. its a custom PSU and so replacing it is not an easy option.what IS an easy option is to be more gentle to the PSu at startup. that’s what this board does.as a side benefit, I threw in a CLI for a management interface. an out-of-band interface or ‘service processor’ (LOL) if you will. after boot you can connect to this simple CLI and turn on/off drives by number or even get their current power status. maybe more things later on. idea here is that you could spin up whole arrays to use them and then spin them down when not needed; or even JBOD singletons./bryan",

I DO hear the 4 drives spin down in sequence (how odd!) and when I do a shutdown-h_now kind of thing, the drives turn off one by one. it may be linux and not the bios shutting them down this way, though.also, you may want special configs such as 2 disks in mirror (software mirror) as the boot ‘drive’. in this case, you do NOT want your controller to be lazy about spinning up the 2 system disk mirror pairs. otoh, you don’t want the controller spinning up ‘data disks’ either, until you say so.the more I think about it, the more I like this out-of-band kind of solution. its way more flexible and the CLI lets you offline drives at-will.

I’m curious what you guys think.right now, the current flows on the normally-open set of contacts. ie, when the relays energize, those are the contacts that gets used and so for the drives to get (and continue getting) power, the relays have to continue getting power and continue to function (work).this could be a failure mode; but I’m not sure if its worth designing around. relays have anotehr set of contacts and I could switch over to those, along with making the appropriate source code change. while the server is up and running, the relays would be in the ‘relaxed’ state and the connections would be held by the spring tension in the relays, not the coil electro ‘tension’.one problem with going with that approach is that during the initial power-on, for some short period of time all drives are connected to the 5v and 12v power lines. the system has to QUICKLY act after a power-on (or even during the climb of a power-on) and push down on all relays to stop the loads from appearing to the PSU at startup. this can be done – but… is it worth it?comments are welcome on the pros/cons of both styles.",

It has more than enough capacity to do its normal functions and power the relays.One thing I have done is use the gray wire on the ATX connector (PWR_OK)to control when the motherboard starts for things like this. The PWR_OK wire stays low until the power supply voltages are where they should be at power on then it goes high. The motherboard will not start until that wire goes TTL high.When you turn on a pc the voltages automatically go to the drives before the motherboard. I was a tiny bit concerned about this because that means the drives don’t get the opportunity that the motherboard has to wait till the power stabilizes before starting.By placing a relay in the patch of the PWR_OK wire you can control when the motherboard starts. You can also monitor that signal coming from the power supply to power transistor controlled relays that then switch the power to the +5V and +12V drive connectors. That means the drives stay off till the power has stabilized then turn on. You could even stagger them (I didn’t ) , to spin up one by one.",

I did think about that. should I seriously go that route? I do like the fact that they will probably be more reliable than mech relays and certainly eat up less power (no coils). their on resistance is nice and low but is there ANY chance they could affect the actual circuit/load? that was my worry. who knows how a mosfet in series will affect some vendor’s drive on the 12 or 5v rails. these aren’t simple light bulbs as loads ;) so I took the very safe route (for now) and went with relays.I knew of dc solid state relays (SSRs) but they are very very expensive and also more of a specialty part. I can find ac SSRs but finding DC ones is not as easy or cheap. and I’m not sure they would fit in the same kind of form factor that the cheap mech relays took up.if this was your data, would YOU use mosfets or relays?",

"content": "Nice post, I could see that coming in handy.Regarding latching relays, you can make them if you have an extra pol on the output side of your relay, you let the IO pin drive the relay coil, and also let the NO (normally open) pin of one of the relay switches output drive the coil as well, with the common pin of that switch to the power supply that drives the coils. The NC (normally closed) pin on that relay switch is left unconnected.When the realay turns on form the IO pin, it will keep itself on due to the second switch in the relay. The coil drive has 2 low-side current sinks, one from the control IC and one from the relay itself. A pulse on the control pin will latch the relay on. Pulling power (perhaps through another relay) is the only way to shut it off.With this “relay logic” as it is called you can make more complex arrangements too, such as pushbuttons to select 1 of N outputs to route an analog signal too. Were pushing one button (or GPIO line on a microC) unlatches the other ones, and selectes the desired one.",

[Viktor] wanted a system to keep his pipes from freezing. The common method of using heat tape works pretty well, but can be wasteful. Many people just turn it on for the entire winter. [Viktor] wanted to
automate the heat tape’s power
so that it only activated during times that the pipes could actually freeze. To do this, he rigged an ATMega8 to a temp probe and is using it to control an ATX power supply. Pretty slick [Viktor].

Repurposing A Click Wheel

We think the click wheel is the biggest contributor to the success of the original iPods. The devices were a brick with a monochrome screen but the user interface was slick and easy to use. [Jason] decided he wanted to
add a click wheel to his own project
. After using a logic analyzer he discovered that it doesn’t implement a common protocol such as I2C, perhaps a deliberate move by Apple to keep the controller under wraps? He managed to get past this hurdle, as seen in the video after the break, by bit-banging the data in from the click wheel and then reverse engineering the protocol.
It’s connected to an AVR ATtiny88 with feedback shown on a character LCD screen. We’re glad that [Jason] tipped us off about this, but he
doesn’t have any code available yet
. We love to dive into the source so the sooner he gets it up the better! We’ve got an old 3rd generation with a bad board that is begging to have the wheel ripped out of it, not to mention the dirt-cheap replacements available on ebay.

I do agree, though, that it’s best to consider the availability of the parts you’re going to use. I think we’d all like immortality for the projects we work long and hard on.

Arduino To Nintendo DS Interface

[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to
connect an Arduino to the DS
. For testing he’s soldered an IDC plug to the cartridge cover pin interface but this only requires four connections. The Arduino can both send and receive data from the DS lite as shown in the example videos after the break. The data access is made possible by making the Arduino look like a controller that the DS is happy to talk to.

Reader [Jimmy] sent us some info about his recently completed
antique radio
to audio streamer conversion. The electronics from the original radio were too far gone to repair, but he took the time to pull apart modern components to provide a polished looking finished project without losing the antique feel. We like it, but we are just
suckers
for that
old time
look. Check out his
blog

If you think there’s never enough computerized numerical control in your life perhaps
the pizza plotter
should be your next project. This is a large 2-axis machine that shoots pressurized sauce onto a pizza crust. It’s a food-grade
RepStrap
and appears to use a
garden spraye
r as a reservoir. They learned their lesson when a loose hose clamp sprayed sauce around the room. We’re thinking this is a bit of reinventing the wheel as pizza-making factories but it’s fun nonetheless.

[MkMan’s]
LEGO spider robot
combines pieces from a Mindstorm kit with a few milled plastic parts. The legs are a locomotive concept called a
Klann Linkage
. They operate in pairs and convert the rotational force from one motor into movement for two legs. Here, a total of four rotating gears moves eight legs, besting
the hexapods we saw a couple of weeks ago
in both leg count and motor economy.
Each limb is made up of five pieces plus one base for each pair. That makes eleven pieces per pair and a total of 44 for the entire robot. [MkMan] milled these parts out of 3/8″ HDPE stock. He’s made videos of forward motion and turning which we’ve embedded after the break. Even on a polished surface the bot looks fairly efficient at getting around.

Amplifier Built Inside A 9v Battery

"amp",

"lm386"
] |
It’s pretty creative to use a 9v battery as an enclosure. That’s what [Osgeld] did when building
this amplifier
. There are several advantages; they’re easy to find, it keeps a bit of the dead battery out of the landfill, and this method provides a built-in connector for a 9v power source. In this case the circuit is built around a LM386 audio amplifier. It’s glued to the back of a potentiometer and wired up with the other components for a package smaller than a quarter. A stereo jack reside in the side of the battery case with a cable and alligator clips for connection with a speaker. Now the amp can be quickly connect to any 4-8 ohm speaker.

Not too long ago
we asked our readers
what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
Solderin Skaters are really making progress. They’ve gotten their printed circuit boards and mounting equipment all set to go, and the code and algorithms are really shaping up. All that and more updates are seen in their latest
video
, and
blog
entry.
>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.
>How did you and your team get together? Any fun backstory you care to share?
[Keywan] came back from Amsterdam with an N900 and everybody here was
envious. We saw the PUSH N900 project as an opportunity to equip
everybody with such a device. Because we couldn’t think about a hack
needed other ideas. We remembered funny things we did as
youngsters and *bam* there was the skateboard idea. We called
friends here (University of Bielefeld) and there (Berlin),
*tada* there was the team.
When we started working on the project we soon realized
we would need additional help to tackle such a big
project in such a short time (6 weeks), so we asked
three more highly qualified friends to join the team.
> Have you and your team worked on any other projects? Cellular related
> projects? N900 projects?
No, this is our first project together. [Jan] and [Sebastian] worked both on
different hardware projects. [Keywan] and [Flo] worked together a
shirt design and other non-technical stuff. [Nick] is involved in
a startup developing mobile applications. He sometimes suffers from
badly designed and closed source APIs during the development on other
platforms.
> What was your main inspiration for your team’s project?
We wanted to enhance a real everyday activity and
create an application beyond game controllers such as
Wii-Accessories and Tony Hawks: Ride.
> How do you think people will react when you finish/release?
We recruit a security team to protect us from fans and
paparazzi. Just kidding. We are curious how/if they will react,
but hope they will like it.
As with all open-source projects, we hope that the
work we did might be useful to other applications in
the future.
> Do you have any future plans with your team? Continued N900 development?
> Update your current projects?
We have not planned past the deadline, but we sure
would like to continue working together.
> What do you think of the other winners?
We like their projects and looking forward to meet them in
London. They are very nice and we are in contact with them.
Everybody tries to help each other. We share code, thoughts and
tips.
> Questions from our commentators.
>
> What are you thoughts on Arduino? Do you intend to use one in your
> project?
The Arduino family is a great timesaver for rapid
prototyping, so we did our prototype with an Arduino. But we needed small and
tough hardware, so we decided to design and build our own PCB.
It is based on the same microcontroller, an ATMega168.
> How is working with the N900 hardware and software?
[Nick] says: It’s like a cybernetic implant which I don’t want to
miss in my life. The hardware is very powerful and to be root on
a more or less normal Linux gives you a lot of freedom. The tons
of possible frameworks are sometimes a bit confusing, but gives
you possibilities like on no other platform.
> What do you think about the movement of cell phones towards open source
> software, such as the Maemo? Do you plan to, or have you ever tried
> Android?
We like Maemo even though it still have some glitches. Open
Source phone software gives you freedom in the hand. Just see
how the community around Maemo provide solutions for problems
Nokia didn’t see as crucial. Open Source on phones rocks!
Most of us didn’t worked much with the Android, but Nick tried
Android. For him it’s pretty painful installing an app for every
single messaging service. Google maps is nicer than the Ovi stuff
though. Developing on Android is a little more fun than e.g.
Blackberry, using Linux. But coding and running for example a rails
app on the N900 in minutes just changes the way you do developing for
mobile devices. You can even code on the N900 itself.
> (If you use a secondary power source, example – to run motors) What kind
> of battery life is expected for your project?
We expect a good hour of battery life (average power consumption
of our sensors boards is about 80 mA and our batteries have 130
mAh capacity. Bluetooth, status LEDs (10 mA each) and the ATMega
drain most of the power, the sensors power consumption is almost
negligible.
> Can we get a list of what you’re using in your project? (example –
> bluetooth sets, motors, dedicated sensors, etc)
Each Skateboard is equipped with two sensor boards. On each
sensor board, an ATMega168, running at 7,3728 MHz (to avoid
transmission errors) and connected to to an RN41 bluetooth
module, samples one triple axis accelerometer (ADXL345) and two
dual axis gyrometers (LPY/LPR5150). They are powered by through
a lithium polymer battery connected with BEC plugs to a
protection module. And of course, a large number of resistors
and capacitors. We used 0603 SMT components.

PHP Runtime Rewritten, By Facebook?

Yes, its true. Facebook has completely
rewritten the PHP runtime
to make it faster and more efficient, and its completely open source. Named HipHop, its described as a source code transformer, changing PHP into optimized C++ which is then compiled using g++. Thus keeping the best aspects of PHP while taking advantage of the performance of C++. Using HipHop, the Facebook web server CPU usage has been decreased by about fifty percent! And who would have thought that this and many
other cool advances
in programming, started at a
Hackathon

I don’t have the quote, but they’ve basically said “optimize your database, stand up memcached, look at your architecture” before you try to move to Hiphop.

Foil Impressioning Defeats Security Locks

Apparently it’s been around for fifteen years but
using foil impressions to pick locks
is new to us. This is similar to using
bump keys
but it works on locks that are supposedly much more secure. This method uses a heavy gauge aluminum foil to grab and hold the pins in the correct place for the lock to be turned. The foil is folded over and slits are cut where each pin will fall. It is then inserted into a lock on a tool shaped like a key blank. Jiggle the tool for a bit and the cylinder will turn. This just reminds us that we’re much more dependent on the good will of our fellow citizens to not steal our stuff, rather than the deterrent that a lock provides.
We’ve embedded a detail and fascinating demonstration of this method after the break. The materials in the video are from
a Chinese-made kit
. We’re not sure where you find these types of locks, but we don’t feel any less secure since
our keys could be obtained from a distance
anyway.
Update:
Video now embedded after the break. The link is down but you can try
the Google Cache version
.

I had a skeleton key lock under the handle and a pin tumbler lock higher on the door. These represented so low security that I usually not cared about locking the pin tumbler, knowing a burglar could open it in 5 minutes.I wasn’t burglarized, my neighbor was. I wonder why as one could enter easily in mine. The answer was simple. My neighbor had only one lock, it looked weaker to the burglars who just forced in.I learned something with that : people who have decided to be criminals often are not knowledgeable about security. Once they are set they will break in, break out, and bye. They are more afraid about your neighbors than about your locks.",

Wasting your life away apart from the rest of humanity. Only people who are ready for psychiatric treatment.My parents have hardly ever locked their door in their life. And why should they?

The very fact that we can get on the net at will and discuss locks as puzzles and toys means that we are not the target market for locks.On the one hand, articles like this show what’s wrong with existing locks and spur people to think of better ones. On the other hand someone else may see this and use it to harm somebody. It’s not the same as a PS3 hack.",

It’s a pointless exercise in petty nationalisms. Every place has its problems. Stop pretending your respective locations are superior – it’s baseless, subjective, and frankly, disgusting.

Poverty is a result of crime and corruption not the cause. People in corrupt areas don’t feel safe to do any extra work because somebody might take it away from them at any moment. The reason people don’t farm in Africa is not because they’re lazy but because either the government soldiers or the rebel soldiers will most likely steal the result of their labor.

If he enters and hears a television on in one side of the house, he’ll just quietly rob the other side and slip away undetected. The grand majority of locks, whatever their brands, are usually pried from the door using a screwdriver just enough to be broken-off using a No.10 vicegrips and then manipulated with a simple screwdriver to gain entry. Those who use strong security gates to block the entry to their front doors are as well un protected. The most secure can be opened in 20 minutes or less.

USB HDD Enclosure To DVD Connector

This is a “why didn’t I think of that?” idea. [Alec] needed a way to connect an IDE DVD drive using USB. Rather than order a connector
he pulled the circuit board out of an old USB hard drive enclosure
and connected to his DVD drive. Bang, recognized and running.
This will prove extremely handy if you have a netbook without an optical drive. We’ve used
Unetbootin
to move
Linux ISO images to a thumb drive
in the past. In addition to getting around the lack of an optical drive, this saves burning the data to a piece of plastic. But, you should be able to use this with a Leopard retail DVD instead of a 16GB thumb drive for
a Hackintosh conversion
. That means you could install Leopard on a netbook without needing a Mac to transfer the disk image to your thumb drive first.

Our Favorite XBOX To HTPC Hacks

Let’s face it, the original Xbox is ugly. It might have looked cool when it first came out but now most would be embarrassed to display that old beast with the rest of their entertainment hardware. This is unfortunate because the
old girl still has some life in her
. If you have tools, time, and talent you can give the box a facelift and bring it back to see the light of day. We’ve got six of our favorite Xbox to Home Theater PC hacks after the break to inspire you.
Xbox mini
by [Ghostavel]
This case was designed in autocad and laser cut from acrylic. The DVD drive was and the HDD swapped for an 80gig laptop drive to save space. A different heat sink and fan added to both the GPU and processor to keep this puppy cool and quiet. To the right in the foreground you can make out a tiny PSU.
Pioneer DVD Case
by [Barney_1]
DVD players are designed to sit in your entertainment center and that’s why they’ve been a popular home for Xbox guts. This hack removed the standard AV connector from the Xbox board and routes those solder points to the connections on a Pioneer DVD player case. An LCD display resides in the window for the DVD player’s display, and a PC DVD-Rom (not pictured above) takes the place of the original DVD tray. The power and eject buttons have been wired to work and the original IR receiver wired to the Xbox dongle, leaving the appearance (at least from the front) completely unaltered.
Xbox Slim
by [Coca627]
This case is made from
methacrylate
. The hardware changes include a smaller PSU, a slim DVD-rom, laptop HDD, and added USB ports. WiFi and wireless controllers have been included in the design. The white is a nice touch and will complement that white Wii that looks lonely next to the rest of your black components.
Minibox
by [Themikesssta]
This is more of a mod than a hack but it’s a pretty amazing one. On the hardware side he did remove some capacitors for less current draw during boot. The DVD and HDD have been swapped out for smaller ones and an LCD display has been added. The case is made from MDF but it’s the paint job that makes this look so good. There’s a total of five coats on this tiny box.
Xbox Micro
by [Bandit5317]
We
featured the Xbox Micro
last year because it’s a marvel of slimness. It’s got a laptop HDD and long-thin PSU and almost nothing else. Some serious shoe-horning had to be done to make the package this thin, and the finished look greatly benefits from those efforts.
Svelte XBMC
by [Richard Wileman]
There’s not much info on this case but we think it’s rather sexy so we’re throwing it in. As you can see, the DVD drive is gone, the HDD is smaller, and cooling has been upgraded with a fanless heat-sink and two case fans. The controller ports were rerouted to the rear of the case and the IR dongle has been built in for use with a remote control. The case cover has a grill above that massive heat sink and we’d be interested in finding out if both case fans are pumping air out of the case, in effect pulling a ton of cool air past the CPU.

After announcing the grand opening of a St. Louis Hackerspace, we received a tip that another group of our readers had an event coming up.
Twin City Maker
of the Minneapolis/St.Paul area are hosting a Maker Faire and art show next weekend. Unfortunately, we don’t have any writers in that neck of the woods, so there wont be an official Hack a Day presence, but we are sure all of you who make it out there will do us proud. Take pictures, wont you?
The Minne-Faire will be located at:
Hack Factory
3119 E 26th St. Minneapolis, MN 55406
Mini Maker Faire 2-6 PM
Art Show & Party 7-11 PM

Beginner Concepts: 555 Push Button Toggle

PIC, AVR, and Arduino are ubiquitous in projects these days and a lot of the time it’s easy to over-complicate things with their use. In this case, [Tod] wanted to use a momentary tactile switch to turn something on and off. Instead of going with a microcontroller
he built the circuit around a 555 timer
. What he really needed in this case is a flip-flop but lacking a chip for that he went with the 555 because it has one built-in. Three resistors and a capacitor later he’s in business, adding another resistor and a transistor to deal with the load switching. We’ve embedded video of the circuit controlling an LED after the break.
This IC ends up in a lot of projects
so dig through your parts bin and give this circuit a try.

That characteristic vertical line is what happens when a few pixels in a column get “too much” charge, the charge gets “smeared” through the entire column as it’s read out. Hence the white line.CMOS doesn’t suffer from this, as it uses a different technique for capturing the frame and reading it out.",

24, Icosatetrapeds have 24 legs. This robot, built by [Monica Anderson] back in 2005 has 24 pneumatic soft legs. The motion is fantastic, like watching some kind of sea creature walk. Though it only goes about 1 meter per minute, we just couldn’t stop watching. The compressors were scavenged from some military equipment designed for nerve gas detection, and the brain is a mac mini. The rest is just valves, solenoids, wood, and tube.
[thanks Tom]

[I-Bot] has put together some libraries that make it easy to
use gaming controllers with an Arduino
. They interface through the
USB host shield
. This means that PS3 controllers connect via USB through a cable or a dongle. With the Wii remote things get a little more interesting. A
Bluetooth dongle
is used to make the connection wirelessly. What we have here is a cheap and easy way to add Bluetooth connectivity to your projects either through the USB Host shield, or by building your own hardware with
the schematics and code that are available from Circuits@Home
. There are several pages that walk you through the protocols using as well as a demonstration video you can see after the break.

I disagree. I’ve rolled my own from 1802s (1978?) to ARM9s and I enjoy the time saved and frustration avoided when I use an Arduino variant with a solid pcb. It is worth the extra $10 to gain 3 hours of “play”. I do more because of Arduino, not less. That said, you might want to try the minimalist approach at least once. Search Arduino circuit BBB and least parts or similar words and you will even find the 5 component AVR (caps,IC,resonator) and versions that do not need a board. Enjoy.",

But, if you look at say a cell phone, which is something similar (but at a larger scale) to something someone may do with a micro. I don’t see them trying to pack an arduino in one of them. So saying “even the pros don’t roll their own” isn’t true. Yes, proprietary IC usage us required, or maybe a pre engineered lcd, but that’s usually the extent of which. It goes back to them using a micro, and building their own package to incorporate it and the surrounding IC’s to make it truely their own.",

It’s a BC4-CORE series chip from CSR, there are other variants of the same chip, most notably BC4-EXT which have an external flash chip, instead of maskrom, containing the firmware. These are flashable, go hunt for a black/red DBT-122 usb bluetooth dongle on google. Finding BC4-ROM chips is fairly easy, just order a bunch of $2-$5 dongles from DX. Note that a lot of the cheaper ones use chinese knock-offs that are a dollar cheaper but support the same protocols (and identify as CSR chips).Another thing is that BC4 chips have serial ports, for embedding them in other devices like mobile phones. The bluegiga modules use BC4-EXT and connect to the MCU via this serial port. I’ve cracked open a couple of DX dongles and found some testpads on the only one that used a genuine CSR chip, but I haven’t tested it yet. I believe BC4 chips are tested in the factory by sending a self test command via serial, so it might make sense to have them lead out.tl;dr the BT dongle in question might support serial connection, thus removing the need for a $~40 usb host shield.",

Today our good friends over at
Woot!
are selling the Leapfrog Didj, a low cost educational toy aimed at little kids. Lucky for hackers out there, the Didj is actually
a linux device
, and gaining serial console access is as easy as
soldering two wires
. The documentation out there is a little outdated, with a number of broken links and stale wikis, but $25 for a portable linux device is a hard deal to beat. A list of sites which might be helpful are listed after the break, as well as the hardware specs of the Didj.
Let us know if you have played around with hacking the Didj before, and if you have any tips for other readers. Don’t forget to
tell us what you do
with the Didj as well!
Thanks to [Mark] for the tips and the hardware details.
(Possibly) Useful links:
Embedded Linux Wiki Page
GP32x Forums
mention the device
GP32x tries to
hunt down the chip ID
Good overview on hardware, etc
The
Didj is also available on Amazon
for $49, but unlike Woot’s sale, will be around after tomorrow.
Hardware Specs:
* Processor: 393 MHz Arm 9
* Display: 320×240 resolution
* One 24-bit 2D layer (no hardware acceleration)
* One 16-bit 3D layer
* One YUV video layer (no hardware acceleration)
* Graphics: API OpenGL ES 1.1–A reduced instruction set version of OpenGL for embedded systems
* Main RAM: 32 MB DDRI 131 MHz
* NAND Flash: 256MB for data storage/download content
* Media Cartridge: 64MB
* System Software: Brio–Firmware is built on an abstraction layer called Brio to make OS and hardware transparent to developers. This means all software must be ported to Brio to run on this device.
* Screen LCD: 3.2 inches, 16.7-Million Color TFT

For those of us who are stuck in the middle of a cold and snowy winter, this project will seem like a stroke of genius. [Jimmy Bui] has
put together this robotic pushing platform
. While it is seen in the video (on the linked page) pushing a snow blower, it seems to be simply bolted on. This means it could push pretty much anything, such as a lawn mower. The platform itself looks like a common layout. He’s using the base of a motorized wheel chair, and some scavenged bits to protect the circuitry. He says that he built it after seeing elderly people having a hard time shoveling their driveways in his neighborhood. They don’t say if he loans it out to them now, but we suspect that he does.

This seems like something of a throwback hack. [WilinNeofoxx] has built
an audio modem interface for use with his Android phone
. A program running on the Android device takes the accelerometer data and converts it into a 9600bps audio signal, kind of like a dial-up modem. His custom circuit board takes that sound in through the headphone jack and demodulates it for use on the serial port of a PC. This connection to controls a flight simulator using
the G1
‘s motion sensors. In the video at the bottom of his post he unplugs the audio cable for a few seconds and you can hear the audio datastream coming from the phone. It’s pretty annoying so you might want to turn down those speakers before viewing it.

All manner of devices from home alarms, appliances all the way down to individual light bulbs can these days be controlled from your home network or the internet. Setting these devices up the first time is complicated, fiddly and proprietary. Imagine having a simple cell/tablet/pc app that lets you enter the configuration parameters, hold it next to the listening appliance and then click setup. Most folks that end up on forums like this know something about Bluetooth, networks or other matters technology, but 80% of other folks struggle getting their gadgets setup and working.This idea is not only simplifying the user experience, but greatly simplifying how gadget designers implement configuration functionality into their products. Imagine the saving in time and money not having to build any user interface into say an internet connected $15 toaster [sic]. Setup is done locally via the phone via acoustic coupling by passing the configuration parameters directly to the toaster, and once connected the toaster is then managed via simple API (rest or SOAP web services sounds great). The user interface is built and run on the web where all manner if complicated and fancy looking human interactions is easily done without taxing the $15 toaster with this burden.The idea is not new or unique. The Electric Imp guys are doing the same thing, but via light pulses from a cell phone screen. Personally I think the acoustic channel is more flexible and portable, all be it a bit more complicated and possibly slower.I can imagine having a single on chip solution (with an ultrasonic mic) and a matching Cell/Tab/PC app that can be deployed in mass on these cheap devices for pennies.I can smell a kickstarter coming on..",

Not too long ago
we asked our readers
what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
The days are getting closer and closer to the N900 PUSH Showcase, and as such the teams are getting more and more stressed. But the team from Sketch Your World was willing to take time of out of their busy day for our interview. As always, keep up to date on the team at their
blog
– they’ve started drawing on the Etch a Sketch(tm), and it even (okay, it doesn’t really, but it’s still progress)
looks like a circle
!
>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.
>How did you and your team get together? Any fun backstory you care to share?
I ([jeez], a.k.a. [Jesus Sanchez-Palencia]) met [Annie] (a.k.a. [Ana Cecília Martins]) and [Calega] (a.k.a. [Filipe Calegario]) during my Computer Engineering graduation.
Someday [Annie] became my girlfriend and we started to work on a few projects together on some crazy stuff that we like to do. [Calega] was also working with some cool projects by his own and one day, talking about ideas, projects, life, universe and everything else, we noticed that we (and some other friends) had this will to work with digital interaction, with hardware/software/human-behavior hacking. And so we decided to create the Wouwlabs group. (wouwlabs.com)
[Patifa] ([Patricia Montenegro]) is a very skilled Architect which works as a Designer. She is a co-worker of mine. One day I invited her to give a lecture on the University about the “Relationship between designers and developers” and the Wouwlabs people really liked her work. The PUSH N900 was a great opportunity to have her working with us and to join us in the Wouwlabs! =D
>Have you and your team worked on any other projects? Cellular related projects? N900 projects?
Well, me and [Patricia] work, mainly, with Mobile development. Yes, we have some other cellular projects and yes, we have some N900 projects. One nice to have is the Qt Mobile Demos (
http://wouwlabs.com/blogs/jeez/?p=135
). Also check Patifa’s blog (
http://patifa.wordpress.com/
) !
Me, [Annie] and [Calega] have worked on several projects before. It is nice to check our blogs (
http://wouwlabs.com
and just click on our names there!) in order to see them. We have even built a multitouch table! :)
Me and [Annie] have one cellular related project. We participated on the first Android Development Contests with a media manager called Jambo.
On this particular project (Sketch your World!) each one of us have a job: [Annie] is our image processing guru and is handling the drawing algorithm, patifa is our designer guru and is handling with the application’s GUI and the final version of the prototype, [calega] is working with the Arduino stuff, assembling everything, and I’m responsible for the Maemo side, developing the application in Qt and porting the needed stuff to Maemo 5.
>What was your main inspiration for your team’s project?
[Calega] should answer this, but AFAIR, he had this fixed idea about Etch-a-Sketch and how hard it is to draw on them. We couldn’t draw anything on it when we were children and we still can’t now that we are grown up! So he thought that it would be nice to finally have some draws on it, now that we can program an Arduino to that for us. :)
>How do you think people will react when you finish/release?
Hmmm, happy?! :P
I haven’t thought about this, since I’m really focusing on get it done in time! :P
But I really hope that everyone like it!
>Do you have any future plans with your team? Continued N900 development? Update your current projects?
We are really considering to do some more crazy stuff with Arduinos and N900s, and maybe do some nice applications to the N900.
We are all fully of ideas and will have to manage to have time for all of them (and to still earn some money with our regular jobs… ;)
I can say that I’m thinking of playing with Arduino+RFID+Bluetooth+N900 on the next months… let’s see… ;)
>What do you think of the other winners?
I really like all projects. Really!
I’m also willing to get to know the other teams! The video episodes are always so nice and the people seems to be very interesting.
HyperHappen did a wonderful job on this contest and they managed to get some very good projects and teams to work on it! :)
>Questions from our commentators.
>What are you thoughts on Arduino? Do you intend to use one in your project?
I’m a fan of the Arduino platform since the very first time I got in touch with it. As a Computer Engineer, I’ve worked with several other boards and micro-controllers before, but Arduino is easiest one. It is so quick to have something running on it! And you can use Wiring, which is a very simple programming language.
It’s amazing how there are some many different people using Arduino these days. From developers to artists!
Yes, we are using Arduino on our project!
>How is working with the N900 hardware and software?
Maemo 5 is a very nice platform! It is user-centered and developer-centered on the same time! It is fantastic how easy it is to develop an application (using Qt! :P) and get it running on your phone.
And now that we have the Qt Framework available, everything became so easy! We can do fancy applications and get them running smoothly on a phone. Yes, it is a PHONE! :)
And the N900 hardware… what can I say?! It’s best Phone ever! It’s best Tablet ever!
You have everything in it!
>What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android?
Yes, I have tried Android. IMHO, Android _looks_ nice. But my compliments stop here. I read a paper about its internals once, and everything seems to be so hackish…
I don’t like the UI itself, from none of the Phones I’ve seen so far that are running it.
I didn’t like to develop for it when me and [Annie] tried.
So yes, I guess that I can say that I don’t like Android. :)
But it’s just me, right?!
>(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project?
We use AC adapters (9v, 0.5 A). So I expect “battery” life time about all the energy that the Earth can still provide. :)
>Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc)
We use BlueSmirf Gold Bluetooth modems, Arduino duemilenove, Ladyada’s motorshield, and two types of stepper motors:
– the ones from SparkFun (
http://www.sparkfun.com/commerce/product_info.php?products_id=9238
)
– the ones from conrad.de: 42MM SCHRITTMOTOR (0.8 BIS 1.5A)
We are also using Etch-a-Sketch (TM), of course, and Plexiglass for the prototype’s stand.
>And yes, we actually had a reader (Joe) ask the following (feel free to omit)
>How often do you change your underwear?
Underwear?! Do people still wear that?!
:)
Just kidding. Here in Brazil (a city called Recife) it’s so hot that we usually take 2 or 3 showers per day.
And I change my underwear every time I take a shower…
Here in Germany, as it’s quite cold this time of year, I usually change my underwear once each two days! =D
Thank you for this opportunity!

[Dave]
figured out the command set for the IM-ME terminal
. It took a bit of sleuthing to get this
pink plastic peripheral
to give up these secrets. He used an oscilloscope to sniff out the SPI connections, then used
a hacked IM-ME
to capture the traffic from a factory-fresh unit. He managed to extrapolate how write data was being sent but he still couldn’t figure out how commands were differentiated from that data. With the info at hand he searched around the interwebs to find that the screen uses an ST7565S controller. Now he’s got custom firmware to make the LCD display do his bidding and we’re wondering what’s next?

Wii Motion Plus Direct PC Interface

You can pick up a Wii Motion Plus module for under $20 and that’s not bad for an I2C gyroscope. This hack
taps into the device through a PC parallel port
. The connection calls for some level conversion to step down to the 3.3v needed by the module. The communication protocol borrows from the
Wii on Arduino code examples
that we saw last year. You can see the
Wii Motion Plus
controlling a virtual cube in the video after the break.

120v Switching
|
Mike Szczys
|
[
"home hacks",
"Tool Hacks"
] |
[
"power",
"switching"
] |
[Kenneth] built
a 5v controlled power outlet
inside of a junction box. We’ve seen plenty of projects that can switch 120v outlets using 5v logic for
refrigerator controllers
,
lighting controllers
, or
grow systems
, but they almost always use solid state relays to facilitate the switching. This iteration uses mechanical relays along with the necessary protection circuitry. The project is housed in an extra deep single-gang box and allows for individual switching of the two outlets. You can see this connected to an Arduino switching two lamps after the break.

I just hacked this together to prototype stuff with my Arduino.Other lacking safety measures aside, I don’t understand why people are complaining about the lack of opto-isolation. The relay is rated for 1.5kVAC separation between the coil and contacts, so I’d think my lack of care in routing is more at fault.",

I would mount it in an aluminum outlet box, so that the relay can dissipate heat into the housing. Ground the housing for safety.Solid state relays switch on zero crossings, so they are much quieter, electrically speaking. This is very important if you intend to do any kind of bang-bang control.One possible downside to solid state relays is that they will *not* switch properly if they are not loaded sufficiently.Whether you use a mechanical or solid state relay, one thing is clearly missing from this design– a fuse in the 110 “Hot” lead. A fuse goes a long way to protecting your switch gear, maintaining isolation, and protecting your home from fire.",

They only cost about $3 for one that will do what is needed here.I would also place it in a metal wall box instead of plastic so if something like a fire were to occur you have better protection as well as the casing being grounded for shock prevention.People saying, ‘use a solid state relay’ need to realize that people have been using this circuit for decades and it is in use in millions of places for a reason, it works and it is safe. The relay is just as good isolation as a optoisolator and often more reliable than solid state relays because it produces no heat and has a very low parts count. Television sets have used this for over 30 years when turning on and off and I don’t see homes going up in flames because of it.One nice hack you can do with this circuit is to buy a cheap clock or clock/radio. Use an extension cord and cut one of the wires , leave the other wire intact. Inside the radio attach the circuit used here to the alarm function(speaker or piezo) and run the cut wire of the extension cord through the relay. You now have a device that can turn anything on at preset times and depending on the clocks functions turn it off after 15 minutes or 1 hour. I used it for years to wake up to my tv . This was back in the 80’s way before tv had alarm functions.",

Hacking A Digital Bathroom Scale

[Micah] was inspired by projects he had seen of people using the Wii balance board as an input. He realized the balance board was overkill, and pricey for many applications. Since it is basically just 4 weight sensors, he thought, why not just use a scale? Often, only one sensor is needed and they’re really cheap from big box stores. He
picked up a digital scale and cracked it open
. As he moved forward, he wanted to keep this pretty simple. There
are other ways
of getting the information from a scale, but they have been generally more complicated than what he had in mind. He ended up bypassing the internal unknown microcontroller and just connecting the analog sensors to his parallax setup. You can read all about the process an download some source code on his site.

I’ve heard wheatstone bridge circuits are good for this sort of thing. A google search for “strain gauge amplifier schematic” turns up a few things.. first hit is a wheatstone bridge + instrumentation amplifier.",

I find that I do a lot of fun projects but I’m very bad about documenting them when I’m done. Holidays are for hacking (in my mind) so I usually plan ahead and do something cool during my time off. This project, which I loving call the Autodine-2009, was a spontaneous event over Thanksgiving that I’m just getting around to writing about.
Our cat’s want to be fed at 6am and are very insistent about it. Like most folks, I’d rather be sleeping at that time of day so
I built an automatic cat feeder
. Now we sleep while the cats eat. We don’t want to rely on a hack to feed our cats when we’re away so I didn’t go the route of
an Internet-enabled multiple-dose feeder
. Instead, I used parts on hand to create a single-serving dispenser on a timer. A servo rotates a false bottom to gravity-feed the cat food. The servo doesn’t have control circuitry so it is controlled through an h-bridge (I did have to buy 2 transistors for that) by an AVR ATmega8 microcontroller. There are two salvaged tactile switches to set the time and timer, and a serial LCD display that I’ve had sitting around for years. Power comes from an old cell phone charger a friend had just given me that spawned the feeder idea when I asked myself “hmmm, what can I use this for”?
I’ll demonstrate this recycled device for you in a video after the break. This wasn’t as hardcore as my
AVR Tetris
build but I’m much happier now that I can sleep in a bit.

Another Take On Roasting Those Beans

"bread maker",
"coffee",
"heat gun",
"roaster"
] |
[Andrew] takes his coffee very seriously and like any hardcore aficionado he wanted to do the roasting himself. The
coffee roaster design
uses a heat gun for the roasting and sources an old bread maker as a vessel. As part of the automatic bread making process there’s a little agitator arm inside which keeps the beans moving while the heat is applied. A computer controls the heat gun, adjust with feedback from a temperature sensor. We had a bit of a laugh reading about melted temperature sensors, but design flaws aside this computer interface allows rather strict control of the roasting profile.
Reader [Youseff] tipped us off about this after seeing the
Popcorn Coffee Bean roaster
from last week.

[Davross] pulled off
an LED lighting build
for his coral aquarium. The module consists of a wooden body holding a 3×16 grid of LEDs. They are mounted to heat sinks which themselves have cooling fans to help keep those puppies from melting. The system is
controlled by an Arduino
which allows for almost limitless lighting options. The photo above shows the LEDs running at 50%. He’s also taken some photos of
the tank in “moonlight” mode
. It’s a long and detailed forum thread but you can skip to some
nice photos of the coral
under the lights or
details about the build
.

First of all, those cheap ebay LEDs will not provide the intensity of light necessary for corals.Also, salt water aquarium are not usually UV-B spectrum. Most saltwater tank fixtures/bulbs are not in the UV spectrum at all.Also, for the tank the size the of the one pictured. $1000 sounds about right for DIY. You need intense lighting from multiple 3watt LEDs to provide the intense lighting necessary for corals. The fish don’t need much light, but the corals do. The manufactured LED fixtures comparable to the DIY in the photo run around $2000.",

I guess fish don’t stare at the sun long enough to go blind.To the guy that wants to grow “plants” in his aquarium, but doesn’t want to leave the light on… In nature, plants get about 12 hours of light per day. You should figure that a plant is going to need at least 8 hours of light per day to grow and not die. A “daylight” (5100-6500k) CFL (compact fluorescent) light bulb that you can buy from a hardware store such as home depot will work wonders. read this:http://www.melevsreef.com/fuge_bulb.htmlLive Rock is only called live rock because of the bacteria growth on the rock, which is highly desirable for biological filtration, but live rock does not need any light. The only exception is coralline algae growth on the rock which needs some light.Corals do not die after two days of poor lighting. Come on, think about it. These corals are sometimes shipped for several days in a box before they get any light. Also, in nature, we often have several overcast days with poor light. The corals do not die from that either. Further, a technique used in reefkeeping is to sometimes intentionally turn off all lights and have your tank in total darkness for 48-72 hours in order to kill off nuisance algae. This can be done once every month or two. The corals do not die from this either.More important than kelvin (but similar to kelvin) is something called PAR (photosythetically active radiation)http://en.wikipedia.org/wiki/Photosynthetically_active_radiationThere are such things as PAR meters that determine if light output is the proper spectrum and intensity for coral growth. LED lighting easily meets the demands of corals (when you select the proper LEDs).There is no longer a debate as to whether or not corals can thrive long term under LED lighting. People have been doing it for several years now. LED technology has improved and become a little less expensive over the past couple years which is why we are hearing more about it now. The future of lighting for reef aquariums is going to change. Probably LED lighting and/or plasma lighting will dominate within the next 5-10 years.

Not too long ago
we asked our readers
what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
Todays team interview is
KAPing with the N900
. They’re N900 hack is the high flying Kite Aerial Photography. Check out what they have to say after the break. And be sure to keep up on their blog – they’ve released
their first test video
just a few days ago.
>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.
Hi there, I’m [Ricardo Mendonça Ferreira], from the “KAPing with the N900”
project.
First of all, I’m a big fan of Hack-a-Day (even if I was not able to
read it for quite some time), so I’m happy to answer your questions.
>How did you and your team get together? Any fun backstory you care to share?
My other teammate is my wife. Lot’s of fun stories, but none related to
this project (yet). :)
Hmm… on second thought, here’s one: my wife’s stepfather was helping
us out when we were filming for the project. I asked him to assemble our
largest kite (a Maxi-Dopero, a bit larger than 4m x 2m) in the
background while I was giving an interview. We couldn’t stop laughing
when we saw the footage: he appeared scratching his had all the time, as
if he had no idea of what he was doing! Because, in fact, he didn’t! :D
>Have you and your team worked on any other projects? Cellular related projects? N900 projects?
We have never worked on anything like this before. We never had or used
an N900 or Arduino before this project.
>What was your main inspiration for your team’s project?
I’ve been practicing KAP (Kite Aerial Photography) since 2005, and I
always wanted a powerful yet simple to use KAP controller, so my
inspiration was my necessity. I already had planned to use an N900 for
this even before the launch of the Push N900 project. When I found out
about it, I did a bit of research and just submitted our project.
>How do you think people will react when you finish/release?
I hope more people will get to know about KAP, the N900, and use our
software and guidelines to develop their own KAP systems.
>Do you have any future plans with your team? Continued N900 development? Update your current projects?
This project is addictive! :) So the answer is yes, I plan to keep
updating my system and also develop other hardware and software
solutions for the N900.
>What do you think of the other winners?
They all have great and interesting projects, each one tackling
different problems and facing different challenges. I’m looking forward
to meet them and their creations in London!
>Questions from our commentators.
>
>What are you thoughts on Arduino? Do you intend to use one in your project?
I never used one before, but decided to use an Arduino Duemilanove after
reading the “PUSH N900 Hacker’s guide”. It will control two servo motors
with commands received from the N900 via Bluetooth.
>How is working with the N900 hardware and software?
Awesome! It’s like programming a desktop system. Since I’m a software
engineer with Unix experience, I felt at home with the device right from
the start.
>What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android?
I’m a big fan of both Nokia and Google for this. You can feel you really
“own” your device if it has one of these systems.
I always admired both Maemo and Android, but when I was looking for my
next gadget, I elected the N900 because Maemo seemed more mature and
with much better support for applications written in C / compiled into
native code. Of course, this opens more opportunities for processor
intensive applications than Android’s Dalvik Java virtual machine.
(Obs.: I know you can write native code for the Android, but AFAIK, it’s
not as simple as is on the Maemo, which supports it on the official SDK.)
>(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project?
This will depend *a lot* on the settings and how the system is used, but
my guess is that both motors and phone batteries will be good for
sessions longer than an hour. This is usually more than sufficient for a
good KAP session.
>Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc)
Here’s my ingredients list:
– two N900 devices
– one Arduino Duemilanove
– one BlueSMiRF Gold Bluetooth modem
– two servo motors
– one Picavet suspension
– one rig to hold the motors and one N900
– one Rokkaku kite
– one pair of gloves
– one winder
– a lot of line
>And yes, we actually had a reader (Joe) ask the following (feel free to omit)
>How often do you change your underwear?
Please see my answer below. Should take just a couple of seconds for
some people do understand what this really is. ;)

Who is ready to win some tickets to the
PUSH N900
Showcase?
The showcase is an event where all
5 teams
from the Push N900 competition are going meet up in London and present their N900 hacks. Including N900s that fly, skate, Etch a Sketch(TM), and more. We also hear there is going to be a poll-dancing robot thanks to
[Giles Walker]
. We were given tickets to the event, and decided to pass them along to our readers.
How can you gain a pair of tickets to this magical showcase? Check out after the break – hope you know a thing or two about resistors.
You’re working with any one of the team winners in the PUSH N900 competition. Your team needs two like resistors in order to complete the project on time.
Luckily your work drawer is overflowing with resistors, and you know that there are only 4 different values since you pulled them yourself from old junk.
You close your eyes and reach in. What is the minimum amount of resistors you have to pull out to ensure 2 of the same value?
That’s it? Yep! Send in your answer to the email
Competition@HackaDay.com
and two lucky winners will receive a pair of Tickets to the PUSH N900 showcase.
Rules and information.
1. The showcase will be the 4th of February, in London UK. If you are unable to make it or out of location – you can still win and your name will be announced. But we highly encourage you to pass your ticket to a runner up who can actually make it.
2. Competition is open to everyone and anyone – except Staff members and Contributing writers of HackaDay. There will be a total of TWO winners for this competition.
3. Entry Period is between January 28th 2010 Noon PST and February 1st 2010 10AM PST. Winners will be contacted and announced February 1st 2010.
4. Winners will be selected randomly from the correct entries using PRNG. The odds of being selected depend on the number of eligible entries received.
5. Winners will be contacted via email and will be asked to provide their first and last names, city/state/country of residence, their Email address, and if they wish to pass on the tickets to another winner. If a potential winner does not respond within 24 hours. We may select the next entry to take the place.
6. The prize will be two tickets to the PUSH N900 showcase per winner. No cash or other substitution may be made. Winner must accommodate their own travel and other expenses.
7. Participation in the Competition constitutes winner’s consent to use of winner’s first and last name, country of residence for promotional, publicity or advertising purposes worldwide in any media and on the World Wide Web, without further payment, consideration, review or consent (where allowable).

Happy Meal Toy Scavenging

We’re sometimes shocked at the electronics included in ‘disposable’ items. For some reason (our tech inclinations?) we’ve been getting those audio greeting cards from relatives and it kind of kills us to see the PCB, batteries, and speaker in what would have otherwise been a fully recyclable card. Now we’ve got several sets of those guts waiting around for our next project.
[David Cook]
cracked open another disposable item, an Avatar action figure
that came as a Happy Meal prize. What he found inside will actually be useful. There’s a battery holder for the three coin-cell batteries, A blue LED (for those
blue LED hacks
our commenters are so fond of), and a piezo speaker. There are some other discrete components that may be of use to you but the first three are certainly a boon for those that are junk scavengers like us.
Has anyone else found some goodies inside these types of free toys? We’d love to hear about them in the comments. But for now we’re just glad to see the first good thing to come out of that annoying market saturation that accompanied
the movie
release.
Incidentally, [David’s]
h-bridge writeup
is our go-to reference for building quick motor controllers from parts on hand, or that can be purchased locally.
[Thanks Gron]

Works a charm! Just gotta finish the lights now…",

Drill-powered Go Cart

Here we have a
toy car modified to use a drill as the powertrain
. [Hans] has thrown a 12v 4.5 amp battery in to power the motor and it tops out around 9 miles per hour. This is similar in concept to the
trash-based go cart
from last week but this time there’s video. He’s built a couple of these and there’s footage of both after the break. Our favorite part is from the first video when dad chuckles with glee from behind the camera as son whips around the neighborhood on the mean-sounding machine.

By your logic, your car would spin in a circle if you got out and pushed only one wheel (hint: it doesn’t).Stunmonkey had the correct response. Most cars use a differential to drive the front or rear wheels (all wheel drive excluded). Only one wheel is actually receiving power at any given time. This is so that when you go around a corner, the inside tire can spin more slowly than the outside tire. Unfortunately, if you get stuck in mud or ice, one wheel will spin and the other will just sit there.There are limited slip differentials, but obviously, this is not one of those.Oh, and nice hack.

Add A Bluetooth Terminal To Your Kindle

This is an Amazon Kindle DX with a Sparkfun Bluetooth Mate stuck in it. [Darron]
hacked the two together
in order to have a wireless serial terminal on the device. There are three big pads in the middle of the Kindle PCB labelled GND, RX and TX, making it easy to figure out those connections. Getting voltage was a bit more difficult. He managed to find 4V coming off of one side of the Kindle’s wakeup switch which works well because the
Bluetooth Mate
has a voltage regulator on board. To protect the Bluetooth module he modified it to pull-up the TX from the on-board regulated 3.3V rather than the 4V coming in from the Kindle.
He’s also been doing some software work on the device now that he has easy access to it. Along the lines of the
Ubuntu-on-Kindle hack
from September, he’s compiled
QT for the Kindle
and written a couple of programs such as Sudoku to show that it works.

Marble Junker
Here’s
a quick and dirty kinetic sculpture
. It’s a track for a steel marble to roll around in with a magnet on a rotating wheel to pick it up and start it over again. Not every hack has to be
a beautiful masterpiece
, they just need to be fun. Of course, if this were
an incredibly complicated piece
it probably wouldn’t have ended up in a links post.
Eight-eyed Computer
[AlexP] has been involved in the NUI Group and in writing drivers for the PS3 Eye. This time around
he’s got eight of them running
on one computer at 60fps. Security cameras come to mind but this could be useful in a lot of projects. We’d be interested in seeing what you come up with. [Thanks Kyle]
Urine-gone
If you have a problem with folks peeing on your stoop then
this is the answer
. [Hannes Nehls] put together a urinating-drunkard deterrent by placing a humidity sensor in the (achem…) trouble-spot and a small tube above. When they pee on the sensor, it pees right back on them. Video available if you click through to the link.
Amplifier Tutorial
If you’re a little shaky when it comes to understanding and working with amplifiers
this tutorial is for you
. It’ll walk you through the basic concepts, then apply that knowledge in a simple op-amplifier circuit.
Severed Heads
It’s always nice to end a links post with something creepy. These faces are made from a cast of the artist’s face. They sing a trio of nonsense and it’s the life-like movements combined with the obviously mechanical backend that tingles our spine. But they’re really just a novelty and not
the real thing
. [Thanks Browneyedalbino][via

[Kieran] let us know about his
hybrid analog/binary clock
. The circuitry behind the clock is nothing too new. An Arduino combined with a
Chronodot
to produce an accurate clock. What we really enjoyed however was the creative implementation of an old British Telecom Linesman’s Multimeter as the case. The
analog meter
acts as the seconds hand, while a another display made of LEDs diffused with stripboard is the binary clock. The end product is nothing short of ingenuitive.

[Simon Inns] designed
a circuit board to retrofit an original Simon
electronic game. This hack is immediately a win because he made sure that his design required no modification of the original case. The new PCB has many improvements. It moves the device from using 2 D-cells over to a 9 volt battery, the incandescent bulbs were out swapped out for three LEDs per button, and the use of tactile switches makes the buttons a lot more responsive (but does require a bit of modification to the colored button covers). Under the hood there’s a PIC18F2550 controlling a serial LED chip and handling input monitoring and sound generation. The video after the break is safe to watch at work, there’s no
swearing involved
this time.

It’s almost entirely a CoB, and the build quality is appalling. (Mine had had two points bridged and then separated with side-snips – eep!)

Robot Band Gives Us So Much To Make Fun Of

[Pat Metheny] has a robot armada backing him up when he performs on stage. They’re going on tour and he’s done an
interview explaining his mechanical band
. Like
the auto-drummer
, this setup uses multitudes of solenoids to play the percussion instruments, each getting commands from a computer. It’s pretty wicked to
see him use his guitar as a marimba controller
; it’s so responsive that he can tremolo and the solenoid follows in kind.
But there’s a lot more going on here. We love to see
crazy facial hair
from
time-to-time
, but this guy’s just got crazy hair! This easy listening isn’t exactly hair-band material but more like live-action
Animusic
. It’s also reminiscent of the automated orchestras at
House on the Rock
, an attraction you may remember reading about in
American Gods
. It’s fun to kid, but whether you like the music or not, he’s certainly talented when it comes to this genre.
[Thanks Grey]

This newest generation of orchestrion is simply amazing, and there’s probably nothing close to it outside Metheny’s room there. You gotta love that such a capable musician was enamored with automation enough to get this kind of thing done and showcase it.HAD investigative reporters would do well to dig deep into this story and expose the genius behind the nuts & bolts of those instruments. Who made them and how? I’d love to learn about that. The solution behind what is probably analog audio input and converting it into MIDI (?) signals almost instantaneously would be quite interesting in itself.Probably something really cool in every nook & cranny of that room.

Not too long ago
we asked our readers
what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
The Haptic Guide team took a moment of their time for us today. Their N900 hack is a belt that helps point you in the right direction with motors. But after our interview we found out they had much much bigger plans. Remember to check
their blog
for updates – including
new video
of their progress (sweet flexible circuit boards guys!)
>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.
>How did you and your team get together? Any fun backstory you care to share?
[Mike] and [Tim] worked together at Dell for nearly two years. After the call center in Edmonton closed, they maintained contact and soon decided to compete against each other in the Microsoft “embeddedSPARK” competition in 2008/2009. Even though they were competing against each other, they worked together often while figuring out the Window CE development tools. [Tim] has strong skills with software development and [Mike] is strong with hardware development. While helping each other complete their projects, they discovered that they made a really good team. When the Nokia PUSH competition came about, they decided to work together on it.
>Have you and your team worked on any other projects? Cellular related projects? N900 projects?
We have competed (against each other) in the Microsoft “embeddedSPARK” 2008/2009 competition and have both made it to round 2 of the 2009/2010 competition as well. We also occasionally work on side projects both individually and together as hobbyists.
The PUSH N900 competition was our first joint venture into the world of cell phone hacking. [Tim] had previously experimented lightly in building applications for Windows Mobile devices, but no other platforms.
>What was your main inspiration for your team’s project?
[Mike] has liked the idea of a haptic compass since he first read about one. We spent an evening brainstorming in preparation for the PUSH competition and the idea of doing something with a haptic compass kept floating back to the surface. We decided to expand on the idea, as a haptic compass by itself was nothing new. Instead, we decided it would be perfectly complimented with a cell phone like the N900 to give it much more capability and even a social aspect.
>How do you think people will react when you finish/release?
We largely suspect people will react in one of two ways. First, there will be a large group of people that have never seen the like before and will look at it with an open mind and see the great potential of the product. Second, there will be a group of people that have seen a haptic compass before and will make the incorrect assumption that the project is just an unoriginal copy of that. We hope that the second group will look at the project again and realize that the belt itself is only a tool to help realize the larger picture.
There is a much larger vision for the Haptic Guide project than most people might realize. The primary focus on the blogs has been around the belt, which is a critical component, but the fact is that it is the N900 gives the project its primary value. The N900 is able to take photos and automatically encode them with geo-tags. These photos can then be shared online or sent to friends and they can use their N900 and the Haptic Guide software to load the photo and automatically be guided in a step-by-step manner to where that photo was taken. This provides a lot of value because you no longer need to type or talk in the location you want to go to, neither by address nor by latitude/longitude coordinates. You just need a photo of the location and the software breaks down the current and target locations into turn by turn directions just like you would find on a commercial GPS navigator. This is where belt comes into play; it eliminates the need to constantly watch the screen or listen for directions. Now you can have the phone in the holder or your pocket and be walking down the street and subconsciously following the vibrations in the belt without any distraction whatsoever from the environment around you. It is the perfect touring device.
>Do you have any future plans with your team? Continued N900 development? Update your current projects?
Going forward, we plan to develop other devices similar to the belt design so there is more than one option of a wearable device. Such things might include a wristband or armband, a watch with lights to indicate the direction, hats, etc. Also, we might look into the possibility of setting up an online geo-coded photo sharing service so you can plan a tour of locations you are visiting. Take a picture of a landmark, post it on the service, and people in the area can find the photo and go to that location if they choose to.
>What do you think of the other winners?
The other winners of the competition have been great. There is a very interesting mix of people across the teams, from geeks to artists. Also, the teams have been great as far as sharing information. For example, when [Tim] was getting started with the application development, Introcept from the Lighthack Crew was happy to share the details of his Bluetooth implementation which gave [Tim] what he needed to get the ball rolling.
>Questions from our commentators.
>What are your thoughts on Arduino? Do you intend to use one in your project?
There is no denying that the Arduino is a great learning and prototyping tool. For our prototypes, we are using the Arduino Mini Pro. We chose this because of the size constraints, outputs and processing power we might need. In a production environment, we would use an appropriate chip and design the circuits directly. But ultimately, this is just a prototype and the Arduino works great for it.
>How is working with the N900 hardware and software?
At first, working with the N900 was like diving into the deep end of a pool without knowing how to swim. But this was largely because [Tim] had never worked with any of the N900/Linux development tools before. Anyone familiar with C, C++, or Python coding in a Linux environment would likely have no problem at all with creating applications for it. The development tools are very compatible. In many cases, all it takes to get a desktop GTK application working on the phone at its absolute most basic, is to recompile the source code using the Scratchbox compiler and copy the files to the phone.
>What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android?
Open source software is almost always a step in the right direction. The real value of the Maemo environment is that the open source tools allow you to simply copy a Python script, for example, from one platform to another and it will just work. [Tim] has considered Android development for the future, but will likely stick to the N900 because of its open platform.
>(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project?
We are currently using a small 2000 mAh Lithium Polymer battery to power the haptic belt. Because of the motor selection we chose to use, the belt gets pretty good battery life: around 12 hours of constant use.
>Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc)
For our prototypes, we chose to use mostly standard modular parts, most of which can be purchased at sparkfun.com. Each belt has the following major parts:
1 x Arduino Pro Mini (3.3V)
1 x BlueSmirf Gold Module
1 x HMC6352 Compass Module
8 x Vibration Motor
1 x Polymer Lithium Ion Battery – 2000 mAh
A double layer leather belt
One Nokia N900 (optional. Without it, the belt acts like a regular compass always pointing to magnetic north)
BlinkM I2C LEDs (optional)
>And yes, we actually had a reader (Joe) ask the following (feel free to omit)
>How often do you change your underwear?
Because there are so many possible amusing answers, we will decline to answer and see what the other teams say.
Thank you again!

The
iPad
,
announced earlier this week
, has been a massive media extravaganza. Some people were elated, and some let down. We’ve been asked over and over what our thoughts on the device are. Join us after the break to find out.
[Caleb]
–My grandma would love this. I really think that she is their target. It is easy to use, portable, and has a custom interface that removes all of the windows style interface cruft. Personally, I don’t need one. I have an iPhone (yes, I know most of you hate them). The iPad offers me nothing that my iPhone doesn’t, except a larger screen.
I am excited though. I’m excited at the prospect of a mid level
touch screen
tablet with an appliance style interface becoming common. I can’t wait to see the knockoffs that can run Linux with a custom interface. The knockoffs that will actually have USB ports, and a non wobbly back. Those same knockoffs that will most likely have a front facing camera. I want one of those.
As far as hackability goes, this might actually be fairly hackable. The
processor isn’t actually as proprietary as some would think
. It is ARM based, and not too different from some other devices we’ve seen. It appears as though
they planned for a camera
. There might even be a spot on the motherboard for it. I fully expect to see it “jailbroken”, but what I WANT to see is the guts modified. I want to see home hackers add external storage (card slot), load a different operating system, up the storage. Then again, I thought the same thing about the iPhones and iPod touches, but haven’t seen hardware hacks at all really.
[Mike]
–This is the first I’ve heard of the iPad. I got soooooo tired of all the apple tablet rumors that I quit paying attention. I run Linux only and unless this device will sync out of the box with my Linux systems I’m not interested. I also don’t usually do hardware hacks on anything that cost me more than $250 but buy so I’m not going to be cracking the case open on this thing anytime soon.
[James]
— The iPad has the opportunity to be a great product, but probably not for me, and probably not for most of our readers. It markets itself to the casual internet user who wants to listen to music, browse Facebook, or watch Youtube on the couch rather than the hardcore photo editor, writer, or programmer. I am excited to see someone like Apple really push the market, and cant wait to see the responses, especially from people
like MSI
and
Asus
. Personally, I’m waiting for someone to make a really great convertible tablet netbook with native support for Linux.
[Jakob]
— I hate Apple products, I mean almost with a passion. But I actually do own an iPhone – and I admit, it is one slick nice device. Small, powerful, convenient – all things the iPad is not. Its like Apple couldnt decide on making yet another iPhone revision or a full tablet PC and decided to give us a semi nerfed iPad instead. From what
I’ve heard, there is no multitasking
and several other features that – if can be included on the iPhone – why did they remove it from the iPad? Final note: being an apple product, its about $500 more then it should be.
(And it doesn’t even come with wings for extra absorption)
[Devlin]
— Meh, I don’t think there is going to be much to do with hacking the iPad, I won’t buy one because I don’t see a reason for having it. If others have the same thought, not many people are going to be buying the iPad and therefore not many people are going to be hacking the iPad.

I’m sure people will still buy it though because a lot of people just go with whatever apple makes.",

You cannot make a device that officially connects to this product without including Apple silicon in your design, for which you pay. Device manufacturers are (anonymously) already complaining about the price of entry into the Apple market. Hobbyists and hardware hackers are written out of the picture entirely. The iPhone could support Bluetooth SPP and connect with many devices, but it doesn’t. It could talk to devices over serial port through the dock connector, but that’s not allowed unless you are a big manufacturer and can pay $4+ per device to Apple. The iPad is the same thing, but the difference is it’s intended to take over a good chunk of the computing sector. There will be people who have only the iPad. I cannot independently make a device that these people can use without Apple’s approval.",

You have to upgrade the internal USB bus to add a new port. Thats no big deal.The big score of Apple is the deal with all the editorial world. They have showed with the ITunes store that they are serious people to the music editorial houses. Almost the same thing about the software developer world with the AppStore. Why not with books?I think those are reasons that are different this time with this tablet PC, and why it may finally boost the launch of this technology.And anyhow, the design is really high-tech.Havent we watched plenty of movies/tv-series these last years that show people with these devices?",

Now we have a platform on which any sort of development environment is outlawed! This is not in the spirit of the internet that I was excited about back in the 90’s.So, what I want to see out of this is jailbreaking go mainstream.

AT&T (and Verizon, others were slightly cheaper) wanted/wants a $500 deposit for me to get an iPhone, which pushes my first month’s bill to just under $1000 when you figure in the cost of the phone and the first month’s bill. The ability to buy 3G internet access “when needed” is VERY appealing to me and I really wish there were other options like this out there.I can definitely justify $660 for a mobile internet enabled browser and SSH client for accessing all the various switches/routers at our remote clinics. It’s smaller than my laptop/bag combo that I normally have to lug around and there’s quite a variety of RDP clients in the App Store that could essentially turn this into a 10″ thin-client laptop terminal.Does anybody else know of any other way to get month-to-month 3G+ w/o costly (less than $100) hardware to buy?

Unlocking Multitouch For Droid And Nexus One

We’re fans of pinch-zooming and that means multitouch. Although the interface is natively supported by both the hardware and operating systems of the Nexus One and Droid phones, it is locked out of the stock installation. You can make
multitouch work on both handsets
if you’re willing to do a little firmware alteration.
The coding has already been done for you, it’s a matter of loading a custom kernel. Both the
Nexus One
and the
Droid
have been rooted, and that’s what you’ll need to do to unlock multitouch with new firmware. In addition to gaining full access to the device OS, you’ll need to load up some different apps that support pinch zooming, etc. Luckily, these are readily available and you may like them better than the stock browser, maps, and photo applications.

[Fridgehead] modified his Simon Says
game to include a dirty word for each lighted button
. This is a real good way to teach kids to swear and to get child protective services to pay you a visit all at the same time. The hardware has been modified to use an Arduino in tandem with an
ISD audio chip
. These chips can record and playback sound. Although [Fridgehead] could have made it say anything he, choose four words you won’t say in front of your mother. We should warn you not to play the video after the break if you’re at work or it’ll be your boss that comes after you, not your disappointed mom.
As we said before, these videos are Not Safe For Work due to foul language.

Maybe someday, but documenting shit isn’t really the fun part to me.People write bad stuff about some of the most amazing things I have seen on this site. In fact I have often wondered if I ever showed something off and somehow got on some blog such as h/a/d would I even want to read the comments? Maybe you yourself shouldn’t… At least not for this “realisation of a stupid idea dreamt up in the pub once that got built whilst I was recovering from a broken arm and had nothing better to do” as you call it. It’s a lot easier to say “hack” I guess.",

Things That Kill You, Hacked For Clean Energy

"virus"

Tobacco and E coli can wreak havoc on your body causing serious damage if not death. Some researchers from the University of California at Berkeley have found a way to take these potentially dangerous organisms and make them do our bidding. By genetically engineering a virus they have shown that
the two can be used to grow solar cells
. Well, they grow some of the important bits that go into solar cells, reducing the environmental impact of the manufacturing process.
Once a tobacco plant is infected with the altered virus it begins producing artificial
chromophores
that turn sunlight into electricity. Fully grown plants are ground up, suspending the chromophores in a liquid which is sprayed onto glass panels to create the solar cells. This types of
creative solar energy production
make us wonder if Thunderdome and
the apocalypse
are further off than we thought.

Android G1 Serial To Arduino

With the ability to get root access to some of these new powerful pieces of hardware we call cell phones, we’re a bit surprised we haven’t seen more interfacing with external hardware. Here’s
an example of some rudimentary connections between an Android G1 and an Arduino
. To do this, you must have your G1 rooted, have the Android SDK installed, and then a custom python program running. There is also a simple level shifter from 3.3v to 5v necessary for the connection to the Arduino. You can get all the details from the instructable. They’ve documented the process quite well adn we’re excited to see what kinds of stuff people come up with.

Face Tracking With X10

"x10"
] |
If you are looking to do some face tracking and don’t know where to start, this explanation of
how to do it with X10 modules
could be pretty helpful. Aside from having, what some could consider to be, the absolute
most annoying website ever
for a company, X10 also makes modular systems for home automation.
X10 also refers to the industry standard for home automation
, so sometimes just saying you did something with X10 can get confusing. He is using the SDK to write custom code for the tracking, which you can download from the project page.

Automated Super8 Film Scanning

"digitize",

For those of you who have been dreading the day that you have to dig out those old family films in Super 8 format and take them to get digitized, dread no more. Now you could turn it into a cool project. [Photobsen] has
posted pictures of an automated system
for scanning and compiling the film into a digital movie. There was already software available, called
CineToVid
, which would take the scanned segments and create a video from them, but doing the actual scanning was quite laborious. [Photobsen] built a quick automated system using an old floppy drive connected to his computer via parallel port. He now scans about 80 seconds of film per hour, unattended.

Rotary Encoding With Your Soundcard

Caleb Kraft

[
"Peripherals Hacks"

[
"rotary",
"stepper"
] |
[Stefan] sent in this project writeup to show us how he
used a stepper motor as a rotary encoder
. Using a stepper motor as an encoder isn’t really that new, as [Stefan] points out, we’ve seen it several times before. He wanted to use this in the quickest simplest way with his computer though. Instead of doing any decoding on a separate microprocessor, he’s connected the stepper directly to his sound card and written code to do the rest. You can download that code and see a video of some practical applications on his site.

Adding A Netbook Keyboard Light

[Vikash] was having trouble using his netbook in the dark so he
added a keyboard light
. He’s got a Dell Vostro A90 which is the same hardware as the popular Dell Mini 9. We agree that the condensed keyboard layout makes it hard to type without looking; just try to find the quotation mark, brackets, and tilde keys! He added an LED to the bezel around the LCD screen in order to shed light on the situation. Now the LED can be turned on using CTRL. An ATtiny13 microcontroller monitors pins 1 and 11 of the keyboard, waiting for the CTRL keypress, then turns on the light when it receives it. This hardware solution means it doesn’t matter if you’re running a
Hackintosh
(like he is), Ubuntu (like we are), or that other OS.

On the Mini 9, the corresponding key combo would be Ctrl-Backspace, but I didn’t want to use a keystroke that would be so likely to be bound to some action in software. As a bonus, the Ctrl key is easy to monitor.tristand – I read and was inspired by your writeup — nice work, by the way — but I couldn’t seem to access the system management bus from OS X. This way I do get the advantage that it works independently of the OS; it even works during bootup or in the BIOS configuration.qwertyphile – I suppose you could accomplish something similar with a handful of components (you’d need a little more than just a flip-flop and capacitor — probably at least resistor and an AND gate), but the ATTiny13 is only a buck and a half and really compact.Anon – I in fact have three ThinkPad X series laptops.

This is an
array of flourescent tubes
that form a display. The video above is just two modules of a ten module installation that [Valentin] and his team are showing at an exhibition in Berlin tomorrow. The connected modules form something of a scrolling 16-segment display (similar to the 17 segment display modules of the
ninja party badges
but much larger). They’re using triacs, optocouplers, DMX, and an Arduino to interface a computer with the 182 fluorescent tubes of the display. Check out a second video after the break to see (or be blinded by) all ten modules pulling 10,000 watts.

When designing legged robots, we generally see an even number of legs. Mainly, we think, it is due to us modelling things after nature. But with robotics, you’re free to do whatever you want. [Iketomu-san] has built this unsettling
5 legged robot
out of parts he had lying around. The gait is fairly interesting. He mentions that it could be used for robot fighting, where the odd leg would serve as a prop from behind and the two legs up front could be weapons. What kind of gait or use can you come up with for this thing?

In case you missed it back in June,
the Palm Pre was rooted
by extracting the Root ROM from a Palm tool used to reset a device with damaged software. A lot has been learned from examining the code inside that ROM but we’re most amused by one thing in particular. If you grew up in the 80’s there’s a pretty good chance you know the
Konami Code
by heart. So did the developers of WebOS, the firmware running on the Palm Pre. By inputting the familiar (UpUpDownDownLeftRightLeftRightBA) set of gestures
the handset enters Developer mode
for connection to the SDK which was
leaked last summer
but is
now in open release
.

HDD Actuated Acoustical Instrument

"string"

This is the multichord,
a one-string musical instrument
built by [Christopher Mitchell]. The string is a 20 pound mono-filament thread stretched between a wooden bridge and the read/write head of a hard drive. The idea is that the vibrations of the string are picked up and amplified acoustically by the sounding box that serves as the body of the instrument. The frequency of vibration (pitch) is changed by adjusting the tension of the string through the application of various voltages to the HDD head. A relief spring has been added to the head to take the resting tension off of it, making it a lot easier to fine-tune the settings for each note. A keyboard made of twelve buttons selects each different pitch as the string is plucked.
[Christopher] is continuing to post great hacks; we’ve seen a
glove input
and a
giant VU meter
from him in the past. Take a look at the multichord in action after the break.

As you noted, I caught myself and eventually fixed the written description.The feedback idea is an excellent one; besides the signal processing aspect, the necessary voltage adjustments might be interesting. A looser string would imply that everything would need to be shifted towards higher positive voltage (negative voltages towards zero, positive voltages away from zero).

Nanotouch: A Tiny AVR Media Thing

[Rossum] is at it again. This time, he has created a
super tiny media device to get us drooling
. You might recall him from the
8-bit device
we showed you before. The Nanotouch is roughly the dimensions of a 96×64 OLED screen(slightly larger than a quarter), with about 1/3 to 1/2 of an inch of stuff packed behind it. The screen itself is mounted atop 4 buttons. This allows you to depress the screen edges for navigation. He does mention that this design needs a little work to prolong the life of the screen, but we really like the intuitive way of navigating. At its heart is an ATmega32u4.
We thought his last version was fantastic, but this one has us enamored. He states he’ll publish schematics and code, as he did before. We just didn’t want to wait to share.
[thanks Joakim]

PS3 Exploit Released

You can now
download the exploit package for the PlayStation 3
. [Geohot] just posted the code you need to pull off
the exploit we told you about
on Sunday, making it available on a “silver platter” with
just a bit of explanation
on how it works. He’s located a critical portion of the memory to attack. By allocating it, pointing a whole bunch of code at those addresses, then deallocating it he causes many calls to invalid addresses. At the same time as those invalid calls he “glitches” the memory bus using a button on his FPGA board to hold it low for 40ns. This trips up the hypervisor security and somehow allows read/write access to that section of memory. Gentleman and Ladies, start your hacking. We wish you the best of luck!
[Thanks Phileas]

"content": "Below is iQD’s statement regarding the recent GeoHot PS3 Hack news, partly it really seems as if he does not read any docs.To quote: “So the PS3 is hacked ? Well that’s nothing more than an urban legend.Altough it’s nice to capture all these HV calls and stuff from a plain (not encrypted) lv1 binary, but this will never lead to a hacked PS3.Let’s have a look. The major security architecture on the PS3 is called the “Secure Processing Vault” and is the most important thing regarding “hacking” the PS3.There is NO WAY for the PPU or even the HV to gain access to the SPU, which is an application running inside of an isolated SPU.Well you can kick out the isolated SPU, like geohot mentioned, but this gives you nothing, as ALL the encryption and execution of applications (HDD encryption, app encryption, decryption, executing, signature checking, root key extraction) happens inside the isolated SPU.To run homebrew on the PS3 you would have to reassemble the whole functionality from the SPU inside a binary running on the PPU. For this you will need the root key.The root key is stored in hardware (not even close to the things on the iPhone). The root key cannot be extracted by any software or hardware means and is essential to ALL encryption/decryption, executing and checking routines.The only way to get the root key is inside of an isolated SPU, as it is kick-starting the hardware encryption facility. There is no other way to do that !Let’s just assume that geohot or some other guys are able to break into the local store of the isolated SPE. There they will just find some encrypted binaries.The key for decryption is encrypted by the root key ! You won’t get anywhere without the root key.Let’s assume that someone managed to do all those stuff from the isolated SPU on the PPU and creates a CFW.There is still a secure booting environment. The first module loaded/bootet is integrity checked by the hardware crypto facility utilizing the root key. So you have also to address this booting stuff. Again, no root key, no booting.So there’s always runtime patching you might ask ? Not possible on the PS3 because the hardware crypto facility is able to check the signatures whenever it wants to.And which part is responsible for this ? Exactly, the isolated SPU. So if you kick out the isolated SPU the system will not boot/run anymore.The PS3 is neither an PSP nor an iPhone. It’s the most secure system architecture of this time !The girl behind this stuff, Kanna Shimizu, is not somebody. Messing around with this is not like saying Bruce Schneier is a n00b.Btw.: forget about all those stories, that certain hackers are or will be employed by SONY. That’s nothing more than another urban legend.@geohot It is OBVIOUS that the HV is PPC. The Cell BE is a PPC architecture, you know ;-) Better read those IBM papers in first place !– iQD”that means he does nothing really, just baypass lvl1 security wich is great but paradox did it before him!",

What really needs to be done is a dump while XMB is running not otherOS, and see what’s in main RAM then. There are also obscure instructions that interact with locked SPEs. Dumping while in XMB require XDR bus modification though, and can also be done on the SLIM.Most people are just going to sit back and criticize though because of lack of skill and/or laziness.",

It’s really not that hard for even a non-technical person to see that getting past the HV doesn’t do any good by reading thishttp://www.ibm.com/developerworks/power/library/pa-cellsecurity/I’m not saying what he did was worthless.

Why Sony haven’t allowed Linux devs access to the GPU/etc before now I’m not quite sure, but the extra memory and faster display is going to be really good for a lot of the PS3 owners I know.. and I might even consider getting one myself…Now… how long before Mac OS X gets a look in on the PS3? ;)",

The game OS is excellent for games and media, but when it comes to the internet… the browser sucks. The “Other OS” feature is genius and works well enough that it makes the first, 2nd, and 3rd gen ps3 worth buying, with the exception of the 20gig (worthless). Now that there is a “hack” to make the other os feature better, it would be in Sony’s best interest to put it back onto the 5th generation. The buzz of this hack alone would boost unit sales… I would try to hack it if I could get my hands on what is needed.",

There is very little information out at the moment, but [geohot] has successfully
hacked the PS3
to have full read and write access, bypassing the Hypervisor. At the moment he’s not revealing the exploit, but with this knowledge it wont be long before the PS3 finally gets whats coming. Keep track of [geohot’s] progress on his twitter,
@geohot,
and
blog
.

Everyone Remembers
Free day
right? [The Ideanator’s] Bus Pirate came in such a nice red box – he decided to make it his
permanent case
.
[Chico] is in the middle of making a CNC, but decided to
make some music
with the steppers in the mean time.
What looks like an old wooden box is actually [Ludvig’s] super sweet retro
arcade cabinet
. Complete with a giant emergency stop red button.
Who says Legos are dead? [Carl] used them to create a simple and cheap
diffraction grating projector
. Including
video
!
[Torchris] used an Ethernet shield exactly as it was designed, sending
data over Ethernet
. Still a nice hack for those needing help working with Ethernet shields and Arduino.
Finally [Robert] let us know about a friends
Arduino Binary Clock
. But we think his elegant use of tape and a sand blaster to
engrave glass
is cooler.

shows us
that hobby R/C airplanes can be built from trash relatively easily. A bit of old tarp and a simple frame work as the body. The rudder is made from old foam packaging. It seems to fly pretty well considering the lack of official design, or aerodynamic features.

The rudder is the moving control surface. Interesting concept of Ailerators….",

IPhone Look-alike On Your Kitchen Wall

[Ryan] and his wife wanted to have
a touchscreen interface in the kitchen
to store their recipes and for various music, video, and Internet entertainment. We know where they’re coming from, we’re quite tired or cleaning flour (or worse!) off of our palm pilot screen after baking. The display you see on the wall is just the interface, a computer is stored in the cabinet below the counter. He’s running Windows 7 and using a custom graphic interface which is intended to mimic the looks of the iPhone. He’s sharing the UI as open source and
has just started a forum
for those interested in trying it out and adding to the available features.
One thing we noticed in his writeup, he prototyped this with an old 2 GHz computer but upgraded the hardware because it was too slow. This pushed to total build price to about $1350 USD. We can’t help but mention that using a Linux based system may have saved him from the upgrade. We know there’s some
extremely powerful media software that runs on light hardware specs
.
[Thanks Hannah]

P3 733MHz coppermine with nvidia geforce 4 64MB and a DVD burner (lol) and ~800 MB RAM. I use amit talkin’s XPSP3 2600 build and will never bury that machine. Everyday I work on machines that are 8 times the power that run at half the speed and just kinda smile at that little box that won’t die lol.As per hulu related tweaks, if you are running XP I would highly recommend TCP optimizer at speedguide.net and/or their post SP2 concurrent connections patch. Again FF’s about:config concurrent connections tweaking are a good idea and there are several guides ala professor google to help ya in that area. I had a similar experience with a laptop I built/fixed for my mom that wouldn’t play hulu smoothly and embarassed me a bit. Laptops are a whole ‘nother ball o wax though :) Best of luck. I know it probably doesn’t help IRL but I still disable any serial, parallel, etc ports I can in BIOS and Win to regain DMA/IRQ channels. This harkens back from my win 95 MIDI days tho so it probably doesn’t apply anymore but like lucky, stinky sweatsocks I still do it on my machines.",

Before we get started, lets just point out that this C64 was broken. He did not take a functional C64 out of operation for this. What he did do, was to
build a hardware interface for for his VICE system
. For those unfamiliar, VICE is a cross platform C64 emulator. [Simon] points out that the old games just weren’t as much fun without the original hardware. Having a broken C64 lying around, he put it to good use. It now acts as the interface for all the original fun stuff.
If you are a fan of the hardware, but just want to
interface it as a normal USB keyboard
, that is possible as well.

Ideas Based On Photo Frame Clock

[Mahto] bought a digital picture frame but the image quality turned out to be terrible. He decided to
turn it into a clock in a unique way
. He loaded up 720 images, one for each minute in a twelve hour period. He then used an Arduino to simulate a button once a minute, cycling to the next image.
This is a simple solution and it works. Visions of hardcore hacks danced through our head when we first looked at this. We’re wondering if there is a way to inject image data into the frame’s memory? How about rewriting the SD card location where the image file that’s currently being displayed is stored, then having the frame reload the picture? Those are projects for a snowy weekend, but we’re sure that [Mahto] finished this hack long before we would have because he kept it simple.
Sooner or later we’re going to need a category for
all
of
these
clock
hacks
.

LCD Backlight Repair

Another broken LCD TV came [Steve DiRaddo’s] way. This one
had a broken backlight that he wanted to fix
. He scrapped his
LCD light table
in order use the inverter. The two televisions were not the same size, nor made by the main manufacturer, but backlights all operate under the same principles. Using an inverter from a bit larger model meant it would have enough power to illuminate the lamps but he knew there’d be a problem with connectors and pinouts. After a bit of testing and creative wiring he got the system back up and running.
He’s got some extra parts left over from each TV including a bunch of CCFL lamps. Sound like it’s
time to add some ground effects to his bike
.

One had a bad fuse which I jumpered (it would have been better to replace the fuse but at least it wasn’t the main one on the power supply). The fuse was surface mount but easy to spot. The other display would come on for one second and then turn back off. I connected a 100 ohm resistor to ground and started poking testpoints on the circuit board. One test point (labelled ‘enable’) caused it to reset and come on for one second again. I hit this point repeatedly while jumpering each of the solder jumper points with another 100 ohm resistor until I found one that would make the display stay on permanently. My thinking was that these solder jumpers were put there because the engineers didn’t know whether that part should be connected or not (probably not the case, but it gave something to go on). After soldering it in place I found it only worked when I was touching it (my other hand was on the other resistor which was grounded) so I put in a 50k ohm resistor to ground. Maybe I disabled a safety mechanism, maybe something just wasn’t right with the circuit, who knows. This was a Samsung TV and it has been working for several months with no problems other than one of the bulbs being slightly dimmer than the rest.",

Want to do quick and accurate focus change with your DSLR? Here’s a
discussion thread
covering dirt-cheap solutions. It starts with a
broccoli rubber-band and a couple of zip ties
. That being a bit chintzy,
the more popular build
seen above uses a hose clamp, rubber band for padding, a drawer pull, a nut, and some threaded rod. If you build it, be very careful not to over-tighten the clamp and crush your focus ring! After the break we’ve embedded a video of what follow focus looks like through the lens and what is happening with the camera during the shoot.

Older cameras had a focusing circle on the view finder. It was split in half and if the picture wasn’t in focus, half of the circle would be blurry. When the picture was in focus the circle was clear. You can get some prism attachments that come close to this, but it’s still lacking compared to the past.2. The focus rings on Canon EOS lens are very lose. That much counter weight on the ring will cause the ring to move, period.

Hack Together A Coffee Roaster

"coffee",
"cooler",
"evil mad scientist laboratories",
"roaster"
] |
For most people, making coffee entails taking a couple scoops out of a can of pre-ground coffee, adding water, and pressing “Go” on the drip machine. To others coffee brewing is an artform, and want as much control over the process as possible. For those without an overflowing bank account for a home roasting machine,
Evil Mad Scientist Labs
have put together a general guide for throwing together a Coffee Bean Roaster and cooler (which is apparently just as important as roasting) from a low cost hot air popcorn popper. The
home roasting scene
is even big enough to warrant its own
Wikipedia page
, which also mentions using a popcorn popper as a bean roaster.
The guide includes some great simple circuit diagrams to keep in mind when hacking your own, as well as a good explanation why you shouldn’t just clip out the heating coil for cooling mode.

Electric Go Cart From Trash

"trash"

A quick lesson on being a good parent. If you make an
awesome electronic cart out of trash
that may not necessarily be stable, or even fully capable of stopping once it gets going, you MUST put your children on it and insist that they drive. Did we mention that the system is full acceleration or no acceleration? Indeed, it is. There isn’t a writeup, and one really isn’t needed. This is dead simple. The parts list will explain most of what is going on, but the look of doubt and fear on the kids face is what really makes this hack worth it. Or is that possibly a look that says “what are
you
looking at?”

You’d try but the thing would jerk forward causing you to pull the clutch out all the way very suddenly. My mom would never have let me ride it with all the almost flipping backwards/sideways going on.Come to thing of it, I hurt myself many, many times on things my dad fixed/hacked for me.

Simple Laptop Conversion

"laptops hacks"

[Jakob] sent in his
method of dealing with broken laptop hinges
. Broken hinges are a plague. We have no less than 4 laptops lying around that are beyond repair with broken hinges. Some are just propped up against things,
some have had box hinges glued to them
and some are just waiting to die slowly from non use. [Jakob] has a nice neat conversion where he basically made a tablet. We’ve seen that before as well as picture frames. His version, while being quite possibly easier than most of the others, has a neat design aspect. An extended lip at the bottom fits in a groove in a plastic slab. All in one PC becomes a tablet in an instant. Not too shabby for a broken laptop. It looks like he needs to pop a touch screen kit on it though.

Wow, that title is flamebait… but give us a chance to explain. [George] wrote some code for
the Arduino that allows it to program another Arduino
. You may be thinking to yourself “this has already been done”. In a way it has, with the
AVR ISP programming shield
. But once the code has been uploaded to the Arduino, you don’t need a computer to program the next chip. This concept turns an Arduino into an in-the-field programmer. Right now
his code
only programs the ATmega328 and it’s a little buggy, but the concept is solid. A fully functioning independent programmer is easy to image; [George] has laid the ground work, the AVR ISP programming firmware has proven this can work with several different chips, and if your AVR has an ATmega328 there should be plenty of room to store the code you plan to flash to the target microprocessors. It’s up to you to put all the pieces together.

One of the best feelings in the world is when one of our posts inspires a fellow hacker to plan, create, and execute his or her own project.
[Russ] let us know about his
Frustromantic Box
which he gained inspiration from the original
Reverse Geochache
we posted about
. For those out of the loop, the box is locked and will only open in a certain location. The current distance to the location is displayed on the screen when a button is pressed, and usually there is a limited number of button presses (3 presses for those that know geometry, 50 for everyone else). As soon as the box is at location, it will open.
The Frustromantic Box uses an Arduino, classic HD44780 display, a servo, and the pièce de résistance EM406 GPS. All built in time to frustrate his wife for Christmas.

You know where you are when you press the button – and a radius (distance) for the circles.Everyone claiming they can use triangulation on this is wrong. Triangulation lets you find the DISTANCE to a distant object by walking between two points and using that distance as a side of a triangle. From each end of this ‘side’ you measure the angle relative to this side that would aim a leg of the triangle towards the distant object. With one side’s known length – and two adjecent interior angles, one can find the lengths of the remaining two sides of the triangle and thus TRIANGULATE it’s position and distance relative to either end of your known ‘side’.Distance is what you ALREADY have from the gps box, and you can’t SEE this point in order to ‘triangulate’ it’s exact location / distance.Assuming you must press the button in the correct spot, and either potential answer from the overlapping circle method is on land, wouldn’t one need 3 _or_ 4 presses to certainly find the goal?",

It is 2D trilateration, similar to the kind the GPS is using, except minus a dimension… Or, maybe if the person who set the location is particularly evil, it could be somewhere off the ground, such as on a particular floor of a tall building or in mid air. This would require 3D trilateration (spheres instead of circles), which would be annoying to figure out how to map. That is not too practical, though, as altitude on GPSs is not incredibly accurate.",

If anybody missed it, click the article link titled “Reverse Geocache,” and the original author describes it fairly clearly. In short:Whenever the button is pressed, the box does the following.1: check counter. If counter is over limit, inform the user, and then shut down. Else, proceed to 2.2: check location. If location is within [error] of [goal location](2km of the center of a particular island in the original case), unlock. Else, proceed to 3.3: get distance to [goal location]. Print a message on the screen to the effect of “You are [distance] away from where you need to be for this box to open.”4: Shut down.So the absolute minimum number of presses is 1, if you happen to be close enough to your goal on the first try. Not likely.The first box took the recipients to the island where they fell in love. I suspect this box also directs the designer’s wife to a similarly significant location, such as where they first met, or where he proposed to her.",

horrifying hexapod
makes us wish we were sitting next to a laser cutter. The parts are cut from 4.9mm plywood and include laser-sculpted sections to allow the twenty servos to properly seat in their mounting spaces. We would suggest that you build it in secret so as not to ruin the surprise when your house mates come home to find this romping around their room.
Sadly, we couldn’t find video of this in action but
go look at this other hexapod
if the still shots aren’t good enough. Adding two legs to the party, you behold the video after the break of the
8-legged spider
milled from ABS.

[Bart]
built a giant laser etcher from scratch
. One of his first test engravings included the Hackaday skull-and-wrenches on a polished granite floor tile (we love it when people do that). He used an
XMOS controller
and
Mach3 CNC software
to handle the device. With just two axes to worry about this seem like an easy project. The difficult bit is controlling, cooling, and focusing the laser. Oh, and if you screw up, you could be blinded, burned or horribly maimed. But if you
start from the beginning
you’ll see that [Bart] knows what he’s doing.

[Kajer] was doing some work with IP phones that use Power over Ethernet. While trying to get this to work with a network switch he decided to
use PoE to power the switch itself
. The best thing about this is he managed to shoehorn all of the necessary bits into the stock case. Those bits include a bridge rectifier, transistor, resistor, and a 5v power supply. Along the way he discovered he can now power the switch off of USB if he wishes.

Nice build, though.If you’ve ever seen a minimally standards-compliant PoE interface, you know it takes a crapload more design than what you could pull off inside that box anyway. One of the biggest things you’d need to do is ensure that ALL of the power supply circuitry is completely isolated. This is NOT only to prevent lightning strikes and all that (that’s the obvious reason everyone says you need isolation transformers), but it’s also because, especially with PoE, the current traveling through the wires produces ground mismatches between equipment, and if the signals are ground referenced, lots of bad things can happen if the wiring is long enough (ethernet signal / power is suddenly below ground, frying your PHY, etc. . .) Here’s a sample, real-world implementation:http://datasheets.maxim-ic.com/en/ds/MAX5941A-MAX5941B.pdfAlso, I suspect that the 75 ohm resistor you took off does something, possibly for balancing the transmission lines.Nice /hack/, though.",

Kajer’s system is isolated- with respect to the PoE wiring. He used the center taps of the isolation transformers. What he needs to ensure is that no one plugs the thing into mains power at the same time as that could cause a ground mismatch and fried circuitry.@Kajer:threepointone is correct with respect to the isolation transformers- they aren’t there to prevent voltage spikes- a transient spike can pass through a transformer through coupling anyway. They are there to prevent ground mismatches.The ground resistors that were on the center taps are there to keep a static charge from building up on the line- if it got high enough it could arc to the PHY or another part of the board and fry something. Since you’ve got PoE configured that won’t happen so removing them wasn’t an issue.One thing you won’t be able to do is pass power along to your phones. 802.3af can only supply about 12 watts to a device (15.4 at the port- 12 watts at the end of the wire). Your switch is already using most of that power. Add in another 8 watts for a Cisco phone and you are over your power budget.As for standards compliance- most PSE’s these days are supplying power over the data pairs. It works with more wiring- and it’s what you have to do with gigabit anyway. I certainly wouldn’t worry about adding support power over the non data pairs- no point.Having said all of this- there are inexpensive PoE chips that you could add instead of that big DC-DC converter that handle switching in the 25kohm resistor- switching it out when power is supplied- converting the 48V DC to 5V- not supplying power to the device until the power is stable, etc. It would require spinning a board- but it would be a pretty easy build.For those that want a turnkey solution- try the dlink DWL-P50:http://www.newegg.com/Product/Product.aspx?Item=N82E16833127059",

The differential signal is unchanged- but the individual components are raised 48 volts relative to ground. This is possible by taking the two parts of the differential signal and feeding them into a transformer with a center tap. You can raise the center tap to whatever voltage you want- but the differential signal on the other side of the transformer is still only going to be the same differential but at ground (assuming 1:1 magnetics which most are- other ratios would cause a difference in the differential signal- but the biasing would still work).",

My measurements were taken while talking and while ringing- that might explain the small difference.CDP will only be a factor if you have it enabled but I did all my testing with it disabled. I should probably do some more testing and see what I come up with. The switch can also choose to ignore it if the load is too high.As for the spare wattage- you’re still limited to 12 watts at the end of the wire- regardless of how much spare wattage the switch has. It’s simply a function of how much current the Ethernet pairs themselves can carry multiplied by 48 volts. It comes out to 15.4 watts at the port itself- and by the end of the Ethernet cable, taking into account losses- it’s supposed to be 12 watts. Some switches “cheat” and push a little more- but it’s generally safest to assume 12 watts. (I suspect you know this and I just misunderstood your comment- my apologies).I also misunderstood your writeup to mean you wanted to power all the ports via PoE from the one switch port. Since you only plan to power the switch and the one phone obviously you should be fine.

[The Longhorn Engineer] is working on
a portable Atari 2600
. Instead of taking the old gaming system and cramming it into a portable form factor he’s designed his own circuit board in a new-hardware initiative he calls Project Unity. The handheld will include everything you need to play, including video, audio, controller buttons, paddle control, and a cartridge connector. For the demonstration, embedded after the break, he’s using the
Harmony Cartridge
to store his Atari ROMs but do note that the system is designed to use cartridges rather than work solely as a
game jukebox

Why Aren’t We Building Our Own Printers?

We’ll ask it again, why aren’t we building our own printers? We’re building
3d printers
,
CNC mills
, and
hacking the ink cartridges
on commercial printers. What does it really take to build say a 300 dpi black and white printer? Something that lets you clean and service the print head rather than throwing it out when the ink reservoir is empty?
Someone has set out to answer these question with the
Openprinter project
. If this interests you, join up and start the revolution.
RepRap
had simple beginnings and maybe it’s time to take the army of self-replicating 3D printers and use them to print parts for 2D printers that don’t
drive us crazy

Just abut every week I read a science article about how they’re using inkjet technology to print solar cells or skin grafts or toxin detectors and other cool stuff. One that’s made from scratch and fully open would be a great platform for exploring and spreading these cool technologies.",

To date I have broken down and 12 scanners and 15 printers.The quality of the parts varies, with the more recent HP models (All in 1 and standalone) using very cheap DC motors and optical encoders with a high resolution encoding wheel.You are more likely to get optical encoders in HP machines, and older scanners seem to produce steppers. I’ve got a bucket full of Mitsumi steppers that are great for little projects. Anything starting with M35 in the list:http://www.mitsumi.co.jp/latest/Catalog/compo/motor/index_e.htmlThe older models have some very nice stepper motors, not likely to push a router around cutting through thick bits of MDF, but enough to push a Dremmel or something higher up (Proxxon) maybe.It is shocking to see how cheaply made the newer pieces are, but unsurprising since they cost less than a new xbox360 game.I’ve taken ownership of a LOT of these for free using a local freecycle service, and the number of times the resevoir(??) drops its guts and shits ink everywhere, or it stops working because they shifted to Vista, let ink dry etc is shocking and very wasteful.I’ll be very keen to see what happens with the open printer project.

Refill kits are available, but manufacturers are already producing cartridge / printer combos that auto-disable to prevent refilling. In order to create third partyreplacement cartridges, you have to deal with the IP / legal departments of eachmanufacturer.You might be able to find an old printer that suits your needs, and you mightnot.@gene and gordunk:When you buy things, there are people who get a cut of your expenditures. Taxes, plastic industries, petroleum engineers, tree cutters for the paper…you can’t entirely avoid it. Ink expenditures are a primary motivator (maybe the only one for many or most people) but others are in it for the hack, for intellectual stimulation, a chance to beat gremlins, whatever. It’s not afailure if there’s not a market ready appliance within six months (I’m not buying any parts before June). But there will be improvements, and maybe some big manufacturers will see a threat and change their ways.So everyone, come contribute, and thanks, Mike, for the write-up!",

"content": "@tehgringe“and it is better quality and is a far better design.” Not true. Simply not true. The older printers are built like fucking tanks, weigh about the same as a tank, and actually use serious pieces of hardware to drive the thing.Agreed as far as build quality. Older ones were built to last in many cases. But not what I was referring to. My old printer was lower resolution, used one black and one 3 colour cartrige, slower, and only printed flat sheet media.Current printer is higher resolution, has 6 individual ink cartridges, prints disks. In my book, better more capable equipment. And to be honest.. Build quality is about the same. My old one was a domestic grade printer too. And not that old. From about ten years ago, when the first domestic ink jets were coming on the market.But something I was wondering.. Does the maker actually need to make the print head from scratch? Why not cannibalise the head from an existing printer? Especially the disposable ones. And if all that is done by any central project is provide the information to do the job, what could the printer manufacturer do? Nobody is stealing the printers. Nobody is selling their product out from under their feet, because the printer is not the profit making product. So no problem really. And I haven’t heard about Epson coming after the people that make that program to reset the cleaning cycle counter yet. Even though it does cut into sales.",

There’s a warm place in our hearts for the original Nintendo Entertainment System. It’s too bad we don’t have that hardware sitting around anymore. But if you do there’s a chance it needs some TLC and there’s always room for a blue LED mod. [Raph] has a wonderful
collection of NES hardware repairs and hacks
that you should take a look at. These include replacing the power supply, fixing the cartridge connector, monkeying with
the CIC chip
, adding a reset button on the controller, converting the audio from mono to stereo, and yes, swapping in a blue LED. Oh, and as a side note, [Raph] gets a bit of extra hacker ‘cred for including “coded manually using VIM” at the bottom of his page. Classic.

Pretty sure everyone on here likes this except you, and the blue light doesn’t look like it fits any differently than the red besides originality based on what you’re used to. Now a lot of people fear change and that’s okay, you just have to learn to grow up and get passed the little bitchness in negatively commenting on things that people are trying inspire others with and are proud of. You fear the blue light. You’re scared of it. But only because it wasn’t you that thought of it. I’ll bet that if you had come up with it, you’d be basking in the jizz of all the people giving you credit. I’m sure that if Nintendo had made their original console with a blue light instead of a red one, then you’d be talking shit about the red light mod. Now tell us why that is? Why do you feel the need to troll on people that are doing cooler things than you? Is it that they did it first and you wish you were getting credit? Well whatever it is, at least everyone on here can see that you’re a bitch, bitch.",

"Grand Opening",
"hackerspace",
"St. Louis"
] |
Here at HackaDay, we are always a fan of a group of hackers coming together to create a place to share ideas, tools, parts, and stories. A group from St. Louis called
Arch Reactor
have managed to secure a new location, and are having their grand opening this Saturday. From 4-10pm on the 30th, they will be hosting an open house, and showing off both the area as well as some personal projects. We plan on being there to cover it, as well as support a hackerspace that is close to home for a couple of us.
They are located on the second floor of:
904 Cherokee St.
St Louis, MO 63118
and feel free to check out their
location page
, as well as their
main web site
.
Edit: Thanks to [kamikazejoe] from the Arch Reactor forums for pointing out the logo issue. Whoops.

Gorgeous Portable N64 Built To Order

[Hailrazer] is at it again with
a new portable N64 build
. He’s done the impossible by improving upon
his last design
. The LCD screen is now mounted flush for a cleaner and smaller case. The controls draw from a lot of different sources; a gamecube stick for durability, a 3rd party N64 controller for buttons, and a PlayStation controller for the shoulder buttons that serve as L, R, and Z (either hand). There is a breakout box that allows two controllers to be plugged in. Combine this with the TV out feature and it acts as a console or a handheld. His in depth demonstration is embedded after the break.
The build log (linked above) details every part of the hack so that you can try to do this yourself. The relocation of the expansion slot requires patience and solid soldering skills. The case work is an art in itself. We speculate that this commission comes somewhere close to $1000 but it’s hard to put a price on quality craftsmanship. We’ve seen
smaller
, but these features and finished look can’t be beat.

Could only have used one cord if I used a much bigger cord or connector. Could have used Cat5 but I thought it looked ugly so I went with headphone jacks.4. Separate Power and charging. Lithium Polymer batteries use a smart charger and a protection board. There are only so many smart chargers on the market and none have enough amps to power the system and charge. So I went with separate charger/power adapters.5.Built in port on the back for memory card/rumble. Buyer wanted an external port and that is the only place left to git it. No room anywhere else at all for it.6.Screen power off when A/V cable plugged in. Didn’t ever figure out how to do this properly and ran out of time. Also this way the first person can play the portable and the second player can play on the T.V :)That’s all. Thanks for the kind comments.

We love it when a PCB comes out right the first time. We’re careful enough with our designs that if something is wrong it’s usually a footprint problem, like we picked the wrong package for the components. Adafruit is helping to make the design process easier by
sharing their Eagle library
. Like the
Eagle library version control
we saw earlier in the month,
this library
is housed on github making it easy to stay up-to-date. The library includes many components (switches, crystals, IC’s, etc.), and fixes some prolbem-footprints, like 0805 surface mount pads.

I know it is a bit getting used too, but it seems so cumbersome with the extra steps in between the schematic and layout mode. The 3D mode is in my opinion useless, why would I want that. Its not altium designer where I can maybe check collisions between parts on board and a casing. I wished that they focused more on usability like a proper multilevel undo function. Better routing options, easier to manipulate grid, heck even push aside and bus routing would make life easier instead of a 3d mode and autorouter.I will switch to KiCAD eventually or make my own CAD program if I cant get used to KiCAD. Maybe I am too much bound to workflow eagle has.I do follow the KiCAD mailing list, and it is pretty active. Maybe i should try out a SVN build instead of the one on the site that is ancient.",

I tried reading the wiki after the last Eagle vs. OSS discussion. I found out that nothing really changed since the last time I tried it: the workflow is fatally flawed. Why would I draw a schematic without specifying component packages and then spend long hours remembering which goes where while assigning package designations to components referred to by nothing but only names which I don’t really want to know or remember? This is weird and broken. Fix it. When I put a resistor in my schematic, I know what kind of resistor it is. In a rare occasion I can swap package while doing layout, but most everything is pretty much defined at the moment I choose my components.",

Turntable Light Sequencer

"sequencer",
"turntable"
] |
[Benjamin] built
a sequencer that uses a turntable and light sensors
to lay down a funky beat. If you like creepy videos with repeated gratuitous corderoy-clad rear-ends we’ve got you covered after the break. Art film aside, he’s got an interesting project. Four light sensors are mounted below the turning record with LEDs hovering above. His hatred for old LP records is apparent because holes must be drilled in a disc for the light to shine through. The four notes in the sequence can be altered in voice and color, along with controls for motor speed and direction. The project also has four manual inputs to add some variety to the repetitive beat sequence. It’s a bit less practical than
the penny sequencer
but fun none-the-less.

Coded Entry Using Your Wristwatch

[Ziyan] and [Zach] built a
door entry system that uses a code entered from your wristwatch
. They’re using the
TI eZ-430 Chronos
that we saw in November. There is a project box mounted over the deadbolt lever. Inside, the wireless fob waits for the watch to connect. When a watch has connected and the correct code is received (using 128 bit encryption) the fob actuates a servo to turn the lock. On the user side of things the code is entered by tapping the watch. The built-in accelerometer picks up these taps and relays them to the door unit.
It’s a heck of a project! Check out their demonstration video after the break. We’d like to see a mechanical option for escaping the apartment in case the door unit fails but otherwise we think this is perfectly executed. We’re looking forward to seeing more projects that tap into this TI hardware.

Anyone could learn your knock or sniff a plaintext rfid message (someone sniffed my bus pass last year, luckily it was a buddy of mine) but very few people have ths particular watch and the message is also encrypted!The only major change I would make is to have a mechanical lever or something to allow you to move the lock from the inside without opening the box if the power fails you.This is a sweet hack and deserves the props! I hope to see more like it!",

The cups are sized relative to the band, so if you were to try a smaller band size but keep the same cup size, the cups would be too small. Instead, you must increase the cups by one size for every band that you go down. For example, if you are currently wearing a 34C bra and your underbust measures 31 inches, then you will most likely need a 32D. On a 30 ” band, this would be a 30DD etc. formula for natural breast enhancement, we thought it was definitely worth a If the band is roomy enough for you to be able to comfortably fasten it on the tightest adjustment, try a smaller band, for example if a 32D is too loose, try a 30DD. Remember that the cup size has to be changed when you move to a different band size – for every band you go down, you must go up by one cup size in order for the cups to remain the same capacity and vice versa.",

[lucasfragomeni] built the
Buzzle
after being inspired by the
reverse geocache puzzle
. The Buzzle was built as a gift to a friend. It’s a tricky gift too. His friend can’t open it until he decodes the words being displayed in morse code via an LED. A word is chosen at random, so you would have to decode it each time you want to open the box. That’s a pretty neat security feature. Sure it’s not the most secure, but it would keep casual peepers out. Unfortunately, the box was empty when his friend received it.

SPHERES (Synchronized Position Hold, Engage, Reorient Experimental Satellites)
are experimental robots made at MIT for the purpose of testing robot locomotion in space. As you can see in the video above, they are capable of maneuvering pretty well. They seem to hold formation fairly tightly. They are using compressed CO2, through 12 different thrusters for positioning. They should be capable of autonomously navigating around each other as well as docking to one another.

[Terry] is planning to launch his
high altitude balloon
within the next few days. As
we’ve seen before
he has gone for a general setup – GPS tracking, environment sensors including temperature and humidity and pressure, and 2 on board cameras – all with an expected height of about 100,000 feet. What makes this project unique is the transmission of live telemetry data to a Google Maps or Google Earth interface.
The planned launch date is Sunday the 24th about 00:00 UTC so long as the Civil Aviation Safety Approval for the launch is passed.
As a final note [Terry] wanted to let inspiring balloon launchers to check out the
UK High Altitude Society
– who have been an invaluable source of information.

I’m using this particular module because I can use it license exempt, as a LIPD (low interference potential device).When used with conventional low/high logic signals in NBFM mode, it’s range is somewhat of a limiting factor – but when used with a varying input voltage resulting in a varying output tone, coupled with a narrow SSB filter on the receiver, the range is excellent (so long as line of sight is maintained – not hard with the balloon in the sky).The UKHAS use the same modules, with the only difference being the transmit power – they’re only able to use 10mW. In a recent launch, they exceeded 400km of range with this setup, and were able to track a balloon they launched which landed in France!As for the Vaisala sondes, these were recovered from sounding balloons launched by our met bureau. The ground setup is prohibitively expensive, but you can decode their data with software like Sondemonitor (http://www.coaa.co.uk/sondemonitor.htm).Terry.",

[Will] enjoys giving hacked items as Secret Santa gifts and this year
he decided to augment a Billy Bass
. These gag items have become a popular hack to
use as a prop
or to
read your Twitter updates to you
. Right of the bat he scrapped the original PCB and sent it to the gift’s future recipient as if he were a kidnapper extorting a family. He then set to work replacing the guts with a pair of PIC 18F452 microcontrollers. One uses power transistors to control the movement, the other controls an MP3 that handles the sound clips. The interface has some LEDs for added effect and uses a dial to select each sound clip which is displayed on a 4×20 character LCD.
The project has several voltage headaches as the motors operate at 6v and 4v, the microcontrollers and LCD display at 5v, and the MP3 is looking for 1.5v. That’s for voltages supplying this Frankenstein’d
schematic
. But he pulled it off, as you can see in the video after the break.

NES Console To Cartridge Security In Depth

[Segher] has reverse engineered the hardware and command set for the NES CIC chips. These chips make up the security hardware that validates a cartridge to make sure it has been licensed by Nintendo. Only after authentication will the console’s CIC chip stop reseting the hardware at 1 Hz. The was no hardware information available for these chips (go figure) so [Segher] had to do some sleuthing with the tools at hand which include some rom dumps from the chip pairs. He was nice enough to share
his findings
with us. We’re betting they’re not of much use to you but we found it an interesting read.

I think segher did a great job, and I found his findings rather interesting to say the least, even if one does not have anything to do with nes/snes it is _always_ a plus to have the ability to share and gain knowledge from not only projects you do yourself. But also projects that other people tackle, and this case is no different. Segher is an extremely talented person, and agree or not as people might.

NXT Hacks: Tanks And Heaters

Here’s a double-dose of Lego NXT goodness;
a robotic tank
and an
automatic aquarium heater
.
The image to the left is a robotic tank powered by the popular Lego Mindstorms NXT kit. The brains rest inside of a tube, including the controller brick, ultrasonic range finder, a gyroscope, and a compass. Two sets of treads surround each edge of the tube making us wonder which end is up? We’ve embedded a video of this beast after the break. You’ll see that the tank is incredibly agile in this configuration.
To the right is an aquarium heater. [Dave’s] kid were growing some tiny water dwellers which we’ve always know as
Sea-Monkeys
. The problem is that the tank needs to be between 72-80 degrees Fahrenheit for the little shrimp to thrive. He dug out his NXT controller and paired it up with the Lego temperature sensor and a
dSwitch
relay. This setup monitors the Aquarium for temperatures between 72-78 degrees and switches a lamp on an off to regulate the temperature. This keeps his kids and the stagnant pool happy.
Now that we’ve whet your appetite for NXT check out the
wiimote operated NXT Segway
and the
NXT Sudoku solver
.

Hey Man, SSH To My Guitar And Setup The Multitouch

"multitouch"

The
Misa Digital Guitar is a digital music controller
like we haven’t seen before. The body, machined out of ABS, looks like a guitar. The player puts theirs hands in the same places you would on a guitar but the lack of strings make it something different.
The left had manipulates inputs in the form of 144 sensors, six in each of the twenty-four fret positions. The right hand doesn’t strum, but uses a multitouch screen to control the inputs. The UI looks solid, something you’ll have to see for yourself after the break. Tieing this all together is an AMD Geode processor running Gentoo Linux. That means this is open source and begging you to make it do your bidding.

[Greg] has been working on a version of Debian/ FreePBX/ Asterisk
for people to be able to drop onto a SheevaPlug. If you haven’t seen it, the SheevaPlug is a tiny computer housed in a wall plug. They made some waves when they were announced last year, and we’ve
spoken of
them
several
times
. [Greg] is offering up the operating system in a pre configured format for SD cards so you can just download it and drop it in your SheevaPlug. Yeah, there’s a little bit of work to do before it will boot, which you can see in the video above. Thanks for sending this in [Greg], keep up the good work.

Read up on FXS and FXO lines.Both are talked to via SIP over wired Ethernet. Web interface configurations, each retail for about $60.It’s best to go Ethernet, no silly USB interface issues, use with ANY phone system you want, VOIP providers directly, or the PlugPBX :)You can get units with a few interfaces or dozens for analog phones or mix your house like mine with IP phones and analog phones via ATA(s). PlugPBX is agnostic, you bring your own interfaces/devices, use Ethernet devices – its what its for ;)",

Servo Hacked Linear Actuator

[AntonB] has
modified a servo
into a powerful linear actuator (think: changing rotational motion into linear motion). The process is simple enough, modify a servo for continuous rotation and then add the custom built actuating shaft. You do of course lose the precision of the servo, but a small price to pay to be able to lift ~20 pounds straight up. Inspiration for such a cheap solution came from his
Planetary Surface Exploration Rover
. Check out a video of both after the break.
[Thanks Eric]

If you had a rotary encoder servo, then yes you can make a precision linear actuator. This is what’s used in CNC mills, though using ballscrews instead of leadscrews, and much beefier servos.You could probably retrofit an existing motor with a cheap rotary encoder and a PID controller and get a high power precision linear actuator. Measure it’s uncontrolled motion for a bit, whack the measurements into EurEQa (or enjoy matlab-induced aneurysms), and add the controller equation to whatever you’re using to drive the thing.

"content": "Hi all,Let me make a start by saying that the reason I decided to post this method is not because I found the answer to every operational aspect of the hobby servo – linear actuator combo :)As EdZ correctly pointed out, you have to get rid off the pot and hence the feedback element, but coming to think of it, when it comes to continuous rotation the pot is not of much use anyway since there is a dead band of about 10 degrees, which leaves the pot’s output floating – not a very good I/P for the ADC of your micro-controller. If one insisted to use a pot they could very easily affix a potentiometer on the output shaft of the servo. Of course it would be better to use an absolute encoder:http://01mech.com/MagEnc:))I believe that servos are great for hobby robotics ventures since are way cheaper than standard gearmotors, all the components come enclosed up to IP64 standard, (protection against low pressure spraying water), they come in a small form factor with mounting flanges ready-fitted.The idea came to me from my planetary exploration rover (my PhD), where I had to make the linear actuators myself using standard DC gearmotors parallel gearboxes quadrature encoders etc etcHave a look:http://www.youtube.com/watch?v=IMmJtw0XYzkThe small servo hack would be extremely useful in making a scale model of my rover. I intend to release the rover designs to the community – the servo linear actuator is a first attempt to draw attention :)The next step is to hack the servo into a PID speed/position controlled continuous rotation gearmotor with absolute feedback (1024ppr). Schematics are already freely available:http://01mech.com/supermodified",

[Dave] Had been working on a
cell phone activated remote start
for his car for a while when we posted the
GSM car starter
. While both do carry out the same job, we feel that there is enough good information here to share. He’s gone a pretty simple way, by connecting the vibrator motor leads to a headphone jack. He’s using that signal to then activate the remote start by setting off an extra fob. Though it is amazingly simple, this version does have an advantage. As [Dave] points out, his cell phone has several features which could be utilized to automate some of his car starts. He can set alarms as well as recurring calendar events to get his car started without his interaction. Lets just hope he doesn’t forget and let his car run too long unattended, especially if it is in a garage attached to his house.

But when it’s 0 degrees or bellow outside and you don’t have a heated garage, a remote start is a huge convenience. I do think it’s funny that most remote starter systems don’t allow using them on a diesel engine. How hard is it to implement a delay in start-up to make sure the glow plugs have heated up. Concerning exhaust. Again, it would be a simple addition of a carbon detector to prevent issues. It would probably be a good idea to have it any way even with auto-shutoff.",

Presumably you would have to bypass all that somehow to make this work, which risks some possible future problems with the insurance company.ANd modern cars not only have a catalytic converter but also various sensors in the exhaust linked to the fuel injection system which ensure that all the fuel used is burnt into water and carbon dioxide.

[Leesam] tipped us off to this cool
tutorial for shaping Polymorph
. For those who haven’t, it is pretty cool stuff. It is a plastic that comes in little pellets. You can melt it down at relatively low temperatures and mold it to the shape you need. We’ve seen it used on several projects, most notably
CrabFu’s swashbot3
. Generally, we see it hand shaped, so it is fairly organic and imperfect. It can be used for more precise shapes though. This tutorial walks us through the easiest way to produce sheets of the stuff to be cut and bent into brackets as well as some helpful tips on getting the best results.

[SeBsZ] tipped us off that
he’s working on a display using RGB LEDs
. He’s etched some nice surface mount controller boards to carry the ATmega8 microcontroller and NXP PCA9635 drivers. This setup uses the I2C bus to address each expansion board of 5 LED modules. Theoretically this hardware would allow for 638 RGB modules but because of power and refresh rate issues he’s set his sights on reaching somewhere between 100-125, a total of about 25 expansion boards.
There’s not a ton to show off yet. But we expect big things from the project. Partly because one of his goals is to generate a display that can be rolled up and easily moved, and partly because his large-scale light bulb displays are so impressive. Take a look at the video of his 60-bulb unit after the break.

ShiftBrites, as the name implies, need to have serial data shifted through each ShiftBrite. This means for example if you have 100 ShiftBrites, to update the color of just 1 LED, you need to reshift the bits for each ShiftBrites. This takes time and is fundamentally slow.Using the NXP chips I’m using, there is one I^2C bus which connects to all the NXP chips. First of all, a single NXP chip handles 5RGB LEDs, instead of just one with the ShiftBrite. Secondly, since there is one bus and each NXP chip has a unique ID, I can change LEDs just by calling out the ID of the chip and then sending the RGB values. This means that if the display gets larger, updating single LEDs will never get slower. OF course, updating the entire display will get slower as the display gets larger (this is always the case).Finally, cost. A single ShiftBrite costs $5. This means that for my display of 100 RGB LEDs, using ShiftBrites would cost me $500. My components did not cost as much, not much less though, to be honest. The actual cost I will post on my blog sometime once I get all my bills together.I am glad you are liking my LEDs, this post might have come across in the wrong way, like I am not liking ShiftBrites. WHile I have never used them, I can see how they would be fantastic to use when you need just a couple of RGB LEDs. I was merely comparing them to my solution, as you had asked :)Regards",

Each module needs 32 bits, on a 255 device chain your update speed with a 4MHz shift clock is about 490 times per second. In reality, you get about 150 updates per second and most of your CPU time is used calculating color effects rather than sending the data. On the AVRs and Arduinos the hardware SPI peripheral works really well.",

[Tom] wanted to take the show on the road so
he added lights to his bike using theater grade control hardware
. The picture above shows three tail lights comprised of 195 LEDs. Built on perf-board, a
DMX512 controller
can display several patterns on each module. The lighting technician (bike pilot) controls the patterns through a series of switches on the handlebars. There’s several pages of details posted including schematics and firmware. This would bring a little extra fun the next time you ride in a
Critical Mass
event.

[lucassiglo21] let us know about his finished
3 axis CNC
(
Translation
via Google). While
home CNCs
are nothing new, we really liked this masterpiece. The CNC is entirely custom, from the electronic control boards (connected to a PC via parallel port) to the physical mill (with an end result of 30x30x15cm workable area). Our favorite part is the use of
screw/band clamp
zip ties to hold the Dremel – a true showing of hacker geekyness. For those who haven’t seen a CNC drill a circle before (and honestly, who hasn’t?), check a video after the break.

Editorial: Fear Of The Unusual
|
James Munns

[
"editorial",
"hacking"
] |
As an engineer and as a writer for Hack a Day, I am used to seeing hardware in all kinds of states; from looking
professionally done
, to
artfully constructed
, to
downright hackish
. Unfortunately in today’s society of manufactured goods, most people just don’t have any experience with homemade electronics. Furthermore, because of a frenzied fear of terrorists, bombs, and IEDs, people who aren’t familiar with hacked or personally constructed hardware often assume the worst.
These assumptions can be inconvenient for some of us, when we have to explain that, “Yes, I made this myself. No, it isn’t dangerous”. The real tragedy is when fears like this are imposed onto children and students who have an interest in building something of their own. Recently there was
a story about a middle school student from San Diego
who built a motion detector into a bottle. He attended a technically-oriented school, and decided that he would bring in his project to show his friends. After a teacher spotted this “Suspicious looking bottle with wires coming out of it”, the device was confiscated, a bomb squad was called out, and the school was evacuated. After using a robot to X-ray and examine the bottle thoroughly the bomb squad finally declared the project safe. Instead of listening to the student from start, thousands of dollars were wasted bringing out the bomb squad and an entire day of school was interrupted because the administrators gave in to fear of something they didn’t know about. The worst part of all of this is that while the student wasn’t formally punished, the school district recommended that he should undergo counseling to correct his behavior.
This isn’t an isolated incident either.
Back in 2007
an engineer who had built one of Adafruit’s MintyBoost kits was stopped in airport security because the kit “Looked like an IED”. In that case the engineer in question stood his ground, calmly explained what it was he had, and why it wasn’t dangerous. Luckily, the police that were called in were of a more rational mind, and after proving that the kit performed as promised (lighting up a USB LED lamp), told the TSA to let him go, kit and all. While this does bring up questions towards the
arbitrary rules
used in TSA screening, that is not the point of this story. Airline troubles have even extended to our friends over at
MakerBot
, who had their luggage searched on the way to CES. The important message to get across is how important it is for makers, hackers, circuit benders, and anyone else who creates or modifies something to share their projects with friends, family, and the internet.
Until people start to realize that not all electronics come from a store, stories like these will keep happening. Education is the only effective tool against fear, and without people like our readers sharing their creations and taking time to talk to people about what the hardware hacking scene is, the general population can’t be expected to know any better. This responsibility to educate is even more important for people like parents, teachers, and organizations such as the TSA and the police because of the influential nature of who they are.
I want to thank anyone who has shared their projects with us, and urge all of you to continue. Our mission here at Hack a Day is to share the amazing projects that are out there, and to help spread the word and interest of hardware and software creation and modification. This mission extends both to experts as well as people who have never seen anything like this before. The knowledge you all share with us helps us spread the word of hacking to as many people as we can get to listen.
I can’t wait to see what else you all have in store for us.
[James].

While it would be easy for most of the people who read this site to build something dangerous into the case of boombox or even an old school gameboy, those items don’t look suspicious. If on the other hand a student brought in a tangle of wires in a home made case and it actually was something dangerous, the teacher and anyone else who saw the device would be in hot water for not saying something. We can’t expect all teachers or law enforcement personnel to be able to figure out a circuit just by looking at it. They might be able to tell it isn’t a bomb easily enough, but what about a taser?The problem is that we are enthusiasts of a weird hobby. We do things that stand out and that is exactly what security protocols are there to pick up on. It isn’t a foolproof system, there will be false positives and missed positives. Just be glad that our hobby is still legal to do in our own homes unlike lock picking which is illegal most places.I’d be all for trying to get the word out to people on homebrew electronics. The main issue seems to be a sense that everything needs to be produced by a company or it isn’t safe. This goes for everything from food to electronics to home repair.",

Maybe in this day and age, if a project is going to be in the public eye, it’s necessary to add intelligent design to minimize the possibility of panic. That being said, It may not even be possible to design a project that can’t be misconstrued. Remember the Mooninites?",

I am surprised, however, at how even a multimeter can be suspected!I do wonder, however, how much of our work would be overlooked by security types if they were professionally ‘finished’ in professional boxes, as opposed to bottles!",

The lady at the desk nearly lost her mind. She thought I wanted to assemble a bomb or something. After patiently explaining to her what I was up to, she reluctantly let me stow it in my check-in luggage.

Apple Magic Mouse on Windows
Looks like some folks snooped around the latest Bluetooth update from Apple and
managed to extract the Magic Mouse drivers
. Now you can use them to take this
complex peripheral
for a spin on Windows. [Thanks Juan]
Component jewelry: From geeky to gross
[Nikolaus] made
a pair of 300k Ohm earrings
for his wife. That’s three Brown-Black-Yellow resistors per ear. It’s geeky but in a subtle way. Much more refined than the gross outcome of this other guy’s
crass nipple experiments
. Need to get the image of nipple-jewelry out of your head? [Nikolaus] has you covered with some
3d printed earrings
.
GTK GPS
Need your GPS data to be accurate within a centimeter? We don’t either but if you ever do, Real Time Kinematic GPS is what you need. Now you can
build one yourself using the RTLIB package
. This is based around
the powerful and powerfully-inexpensive Beagleboard
. [Thanks Jan]
Messy music
It warmed up here a bit this week and things got slushy. Our Galoshes are nice and water-tight but [David’s] have a big hole in the side and are
filled with a mini-keyboard
. He’s chosen a rubber boot as the housing for a circuit-bending project. It’s a nice touch that
the hidden keys are still playable
through the flexible rubber.

Free Day Recap Video And Book Recommendation

SparkFun’s free day came and went as entertainment for some and an infuriating event for others. They filmed some video in their office during the madness to give us
a look at how it went on their end
. We find it amusing that
Solarbotics
, one of their competitors, sent them flowers with a card reading “Rest in Peace SparkFun”.
According to [Nate’s]
original post
, the concept of free day was inspired by reading [Chris Anderson’s]
book
“Free: The Future of a Radical Price”. We recently finished reading this wonderful work and we’re making it our next book recommendation. [
Chris
] is editor-in-chief of Wired and has had a ring-side seat as the digital world rose around us. He takes a historical look at what the price of free really means, defining cost by adding more terms like Gratis and Libre to the mix. If you have a good handle on the companies that have defined the 21st Century business model so far you wont’ be able to put this book down.
Now, we should mention something that is remotely related to hacking since we try to do
that sort of thing around here
. The SparkFun post also reminds those folks lucky enough to get a $100 credit to chronicle and share their projects. We’d love to see them too so get your projects written up and
send us the dirty details

SparkFun’s been stroking itself pretty hard over this one but they fail to mention that some people had credit card problems, a few black-hat’s had claimed to have gotten access to much of the valuable information their servers, and that many of the successful orders were to those who cheated in some way.Another gripe was that it was more and more difficult to get an order through the further away you were from the company’s headquarters. Admittedly, that’s simply due to the fact that communications takes longer, but they could have done something to even things out and make it a little more fair.The real kicker is the awful book that inspired them. It’s full of plagiarism, from Wikipedia no-less. It pushes the old “give them something for free, but only if it benefits me” trick, which is already extremely common business practice and not new knowledge. The trick has been known as “Give ’em the razor for free and sell ’em the blades” for a long time. Anderson comes off as a hack and teaches us nothing. His book has a value of less than free.",

If this free day serves to provide kits and electronics to even 50 people who would not have otherwise experienced what is a truly rewarding hobby then wouldnt it have been worthwhile? i personally would forgoe my share to provide someone else with an opportunity to develop an interest in this field because i have more than enough electronics crap lying around my room to keep me occupied and as a fellow enineer im sure you do to.As for the servers well that is your area of speciality and not mine, i will take your word on that even with the smack of sarcasum in your tone.",

Sparkfun really did a great thing, but it’s important to remember that there is no altruism in the business world(though this is as close as it gets). What I mean is, while they gave away so much, it would be extremely foolish to not use the event as an opportunity to expand and grow.With that said, I do still feel a bit angry thinking about the various ways participants of free day could have(and probably did) take advantage.

I then saw time out after time out trying to checkout.Had it just come back 1 sec later and said sorry… you’re too late I would have been fine with it.The impression I am now left with is that the sparkfun site is a steaming pile of frustration. I personally won’t be buying from them again not because they “screwed me”… they didn’t have to give away anything… but because I now very thoroughly associate them with a very frustrating experience.So Sparkfun has taken someone who happily tossed them lots of cash in the past… despite their poor pricing… to someone who is extremely unlikely to shop there again.If all the freebies went to new enthusiasts: great!

[Dave] hosted a one day seminar at the Illinois Institute of Technology which focused on
rapid electronics prototyping for those with little prior experience
blinking those LEDs. As the defacto standard for novice prototypers it’s no surprise that he gave an Arduino to each team to use as the controller-computer interface. He started the day by getting the
Firmata package
up and running. Firmata is a set of libraries that make communications between software and a microcontrollers simple. In this case, each team developed a Flash game that used data from the Arduino as a control.
Several rudimentary games resulted from the day. We’ve embedded video of two of them after the break for your enjoyment. Lion Vs. Pig uses potentiometers, a distance sensor, and an arcade button to play a game of
cat-and-mouse
(well, Lion-and-Pig really). The other is Kick the Cat, a game that uses a flex sensor and force sensor combination as input. This is something of a virtual mini-basketball game that uses a springy material to launch a virtual feline at a target.
These teams already had a background in code, but the hardware was a new endeavor for them. Arduino helps to break down this cross-over barrier and we think this will result in more people to contribute to open source projects, and falling hardware prices due to a larger volume of demand.

It’s also nice for a quick and dirty “can I do this?” type project, where you just want to see if it can be done. Or more importantly, it is good way for someone with no experience to get their idea into a working prototype.The reason I “hate” Arduinos, is because people don’t use them to prototype. They just put the whole Arduino into the project and call it a day. I don’t even use the Arduino to prototype, I use PIC and a breadboard, but this is because I have a background in programming. I love C and ASM, so I’m comfortable prototyping with them.

I started my discoveries with PIC WebServers, but never really understood the basics of C programming, let alone ease of development that came with Arduino. It wasn’t more than 3 months after playing with the Extruder Controller from a RepRap, that I decided to move beyond the Arduino and design my own board specific to whatever projects I wanted.And using the Arduino as an instructional platform is a very good start to the MCU novice. In that its development IDE+User base/tutorials are very numerous and helpful. As well as easy to understand. Much nicer than just throwing some ATMEGA168 TQFP’s at someone and saying get crackin’…",

The Most Complicated, And Simplest Binary Clocks.

We were going to take a break from posting clocks. Really we were. This one came in the tip line today though, and we just couldn’t pass it up. [Alex] has built, what might be the most complicated clock we’ve seen. At least, it would appear that way initially. This
Binary clock
shows Hours, Minutes, Seconds, Days, and Months. He started with a picaxe, but eventually settled on an Mbed. Yes, he knows it is overkill, but it worked out pretty well.
As for the simplest, that came into our tip line as well. [Toby] sent this in, and agrees with us that it is hardly worthy of being called a hack. However, in light of the complicated one above, we didn’t see any harm in posting its opposite. Check it out after the break.
That’s right, he just printed a new face. Like we said, it doesn’t get much simpler.

The Pololu 3 Servo Hexapod

Here’s a great tutorial on how to make a
tiny hexapod
walker. While this was written specifically for a kit that is sold by pololu, we like the simple layout. You could implement your own electronics if you prefer something else. If you want to follow along with their components, you’ll end up with a fairly small and decently agile hexapod. Sure the legs aren’t articulated at every joint, but the effect is workable. This is probably the first 3 servo walking hexapod we’ve encountered and we’ve
seen
a
pretty
decent
amount
of
hexapods
.

While we’ve been told all of our lives Wiis and trains just don’t mix, they never said anything about Wii Nunchuks. One terribly abused joke later, [Ken] tipped us off about his
Wii Nunchuk controlled train set
.
By utilizing
Digital Command Control
(think pulse-width modulation) with an Arduino, he is able to have full control over the trains direction and speed. The other part of the equation is a Wii Nunchuk and
adapter
. The setup should be pretty self explanatory, but there is
an Instructable
for those that need more help.

"content": "I was about to post that his model looks like it’s made from clay, then I noticed that the track is N scale.I’ll put that aside from now to make my major gripe: This has absolutely nothing at all to do with DCC, not even a custom protocol. He is simply putting PWM power to the tracks. If he wanted to do this properly, he would should give constant DV power to the rails, and use a micro (ATtiny would work perfectly) on the train itself to provide variable voltage to the motor. The rails wont act like an antenna this way, and you can make the trains do some cool stuff, like individual profiles about speeds, lighting, etc.",

"content": "Read the original post.“[DCC] seems a bit much for a four-foot layout, and there is not much by way of hardware decoders for N-scale (yet). Another alternative is to just pulse the DC signal to the track in a scheme called pulse-width modulation. Instead of variable voltage, maximum voltage is applied for variable widths of time. It seems a little crazy, but it works so well that it is used on large industrial motors. The big advantage for model trains is smooth operation at slow speeds – a big plus at Dawson Station.”",

"content": "If he is using standard DC trains there is a slight risk of damage, or at least that is what the E-Z command manual says, though I realize this is not real DCC. What I want to know is has anyone tried to hack an E-Z command controller to work on a PC or boost the power. They use the Lenz X-Bus interface and have a serial I/O port on the back which you can use a separate walk around controller with. I was wonder if this was some straight forward serial communication or are they encoding it. I am new to all this train stuff but would love to hack the system I have with some heavy modifications.",
