[Simon Inns] is still hard at work making USB connectivity for PIC microcontrollers easier for the hobbiest. He’s released
a framework for PIC based USB devices
under Windows. It includes the firmware needed for USB compatible 18F PIC chips as well as a C# class library and example programs for the Windows side of things. This goes quite a bit further than
his PIC-USB tutorial
but with little added effort on your end of things.
We do our USB prototyping on a breadboard just like [Simon] did in this example. He’s got a nice little USB-B connector breakout that is easy to plug into the breadboard. If you prefer to have a more stable development area, check out
the one he designed
. It’s a single-sided PCB made for through-hole components with just a handful of jumper wires.

LEGO Gearbox – Seven Speed Plus Reverse
|

[

"lego",
"sequential"
] |
We know LEGO is a very versatile medium to build with but this is beyond what we considered possible.
Seven speeds and a reverse gear were built into the gearbox
for this LEGO vehicle. It’s not completely an original design, but adds to the five-speed design found in
a ten-year-old LEGO set
. See it demonstrated in the video after the break. The design uses a
sequential gearbox
; shifting is accomplished by clicking the stick up or down depending on how you want to shift. If you’ve got enough parts on hand you can build this using the
assembly photos
that [Sheepo] posted.
Can’t get enough of the gears? Check out this
model of a double clutch transmission
.

If you think that Arduinos are overkill in most projects we can do one better for you. [Jack Gassett] has
a virtual Arduino running on a Field Programmable Gate Array
. We checked in with [Jack] back in November to see his work with the
AVR8 Soft Processor
, an FPGA version of an AVR chip. Because the Arduino uses AVR it wasn’t too much of a leap to make this Arduino compatible. We’re lacking in imagination when hit comes to using this method productively, but we’re sure someone will find a way.

It will be an unlimited ethernet implementation for a very low price.http://www.gadgetfactory.net/gf/project/rmii-eth/We are also looking at a USB host controller addon that would cost less than $5 in parts.

Diffential PHY for ethernet and USB are examples, we are making modules that just plug in so you can use the cores without designing a circuit. You could, of course, use a development kit but development kits are overkill that you cannot realistically sell once you make the next greatest gadget on it. With our open source boards you can sell what you create and keep the price down by only including the hardware modules that are needed.Using the IP cores from Xilinx, Altera, and opencores takes a lot of specialized skills. Our goal is to make an environment that provides access to all the great cores out there without the overhead of learning HDL and synthesis tools. It is the same thing that the Arduino did for microcontrollers, simplifying the technology so it is accessible to more people. We are trying to do the same for FPGA’s.With this Arduino on FPGA project you can start using an FPGA without learning one thing about FPGA’s. This lets you start learning what you need as you go.That is the goal anyway, we still have a long way to go.Jack.",

So the solution of open cores that are exactly suited to the needs (I/O, RAM, timers) is the best way to go (my opinion of course).The great thing with Arduino is the IDE and the standard library. It is simple enough to be shared by many and reach a critical mass that makes it a success.There is a wide gap between the skills needed to program an Arduino and working with a FPGA. But when you consider the lengthy catalogs of microcontrollers, a few FPGA boards could support all this variety and more, with incredible ease for the user to adapt the resources to its needs.It would still be overkill, but with a limited number of standard board the economy would be real.There is a need to automate (or simplify) the process of designing and synthesizing the needs (I/O, timers, etc.) around an open core, and then provide the same IDE as the Arduino but with libraries adapted to the open controller core.That will be the best of both worlds.",

"content": "@AnttiThe AVR8 core is one of the great cores from opencores. The current Butterfly Boards have an 8Mhz clock but any clock speed can be easily generated with the four DCM’s (Digital Clock Managers) in the Spartan 3E. (I chose a low speed 8Mhz clock to keep as much high speed signals off the dual layer pcb as possible.) Right now I’m just passing the 8Mhz clock directly to the core but the next step is to pass it through a DCM and double it to 16Mhz. I’ll also increase the memory to 16KB. Currently 8KB is implemented (I want to include a Logic Analyzer core so the Arduino pins can be monitored without connecting any leads so I left some BRAM’s empty).The Spartan 3E’s DCM is able to run up to 300Mhz so theoretically the AVR core could run up to 300Mhz but realistically it can probably run up to 100Mhz. Only testing will tell, it can definitely run faster than 16Mhz.I spent quite a bit of time running the AVR core in a simulator while trying to get everything to work (turned out the problems were not with the core itself). The pleasant surprise was that everything I observed and compared to an AVR simulator was clock cycle accurate.I was caught a little off guard by this hackaday submission, I was going to submit it myself once I had some Butterfly One and Butterfly Uno boards ready. So I was caught with a very limited supply of my older boards. The aim of the new boards is to really bring the price down. The Butterfly One should have a price of $40-50 and includes a ft2232 chip for fast programming. The Butterfly Uno is meant to use an Arduino as its programmer which eliminates the need for the ft2232 chip and lowers the price even more. The target price for the Butterfly Uno is $30-40.Jack.",

Actually, I’m ignorant if there are any other than “a two stage, single level pipeline design” (from Wikipedia) in the low end AVR’s.I guess you use Xilinx’s WebPack ISE for your work?By the way, I myself try to get my Verilog code so clean, that it works on the FPGA itself right from the start, that I wouldn’t need to use that quite limited simulator that comes with WebPack,and which usually doesn’t correspond with a realsynthesized core very well. E.g. a constructthat might work in simulator allright, eitherdoes not synthezise at all, or synthesizesbut functions in a different way.If you are using WebPack, could you showits summary (and maybe other) report files(they are HTML or text files mostly),to get an idea how much of the resourcesof that Spartan 3-250 (???) the AVR-coretakes, and how much is free for other purposes?",

Very true that behavioral simulation will work great and then not work in the implementation. With the AVR core I have seen the same results in both. Ruslan Lepetenok, the original author did a great job with the core.Several of the AVR opcodes take more than one cycle, what I saw was that the amount of cycles each opcode takes matches the cycles on the FPGA clock. So if an opcode takes one cycle according to the Atmel datasheet then it takes one cycle on the FPGA. Those that took 4 cycles also took 4 cycles.

I figured that I wanted a proven commercial processor and thought the $500 EDK fee was worth it for stability.

Only time will tell how stable it proves to be but I am very optimistic that it will be fine.The great thing about picoblaze is its small size and speed.

Can’t say much else about it yet but if it works the 100k Spartan 3E chip will be much more useful than it is now.On a side note, once there is external RAM in place we will be able to bring things like a Java Virtual machine, uClinux, and a x86 processor to the Butterfly Platform.

Enjoy this 20 minute
video dissection of a Roomba 4000
. There is lots of great information here, as [Dino] does the dirty work. It is pretty dirty too. Remember, the Roomba is a vacuum. What a pleasant way to waste 20 minutes of your morning. Part 2 is after the break.

The suction is great because it doesn’t blow as hard as a standard vacuum, which means that it doesn’t blow cat hair across the room before it gets to it. The beaters work great on the low pile area rug that we have in the living room and it is also safe for our hardwood flooring. We use it in the kitchen with ceramic tiles and in the bedrooms with medium and high pile carpet. It doesn’t really like the high pile but it does get through it, just burns up the battery a lot faster. It cleans two rooms easily on one charge, but it takes a little over an hour, that’s why we set it to work while we are out of the house. Find one on ebay for cheap and you’re good to go.

[malikaii] needed to set up some kind of
tripwire style alarm system for his office
. His bosses kept sneaking in to find him slacking. So, like any loyal hacker, instead of just working harder he built an alarm system. After a failed attempt to recreate an IR alarm circuit he found on the web and built from old appliance parts, he found the Hack a Day article about
harvesting McDonald’s toys
. The end result was a fully functional IR detecting alarm for the office doorway. This is pretty simple really, the best kind of hack.

Tiny Tube Amp For Headphones

We like to check in from time to time on the scratch-built tube amp scene. [Rogers Gomez] recently posted his build of
a headphone tube amp
. This is somewhat related to
his work from 2008
, but this time around it’s simple enough to serve as an entry into amplifier construction for beginners. The PCB layout is clean and simple, makes for easy board etching, and it’s small enough to fit into an enclosure that can pass as a headphone accessory. Only one tube is needed, with a total parts bill coming in around the $50 mark. If you build it, heed his advice on testing with a pair of cheap headphones before you risk plugging in your prized pair.
Still want an amp but don’t care to source the vacuum tube? [Giovanni], who sent in the original tip, build one a while back and
housed it in an external CD-ROM enclosure
.

Giant Robotic Giraffe Getting A Giant Robotic Facelift

If you’ve had the opportunity to attend the annual Bay Area Maker Faire, you’ve likely encountered
Russell the Electric Giraffe
. Modeled after a small Tamiya walking toy scaled up to the height of an actual giraffe, Russell was created by [Lindsay Lawlor] in 2005 originally as an “art car” providing a better vantage point from which to enjoy the
Burning Man
arts festival. In the intervening five years, the Electric Giraffe has enjoyed face time in dozens of parades, trade shows, magazines and television appearances.
Scattered about [Lawlor’s] living room floor at the moment are the giraffe’s dismantled steel skull and several massive Torxis
servos
(the red boxes in the photo above) — Russell is being upgraded. One of [Lawlor’s] goals in returning to
Maker Faire
each year is that he not simply present the same exhibit time and time again; the robot is continually evolving. Initially it was little more than a framework and drivetrain, and had to be steered by bodily shoving the entire 1,700 pound beast. Improvements to the steering and power train followed, along with a “skin” of hundreds of
addressable LEDs
, cosmetic improvements such as a new paint job, and technological upgrades like interactivity,
radio control
and speech. His goal this year is to bring expressive
animatronic
movement to the giraffe’s head and jaw, hence the servos, push rods and custom-machined bits currently strewn through his living space-cum-laboratory.
[Lawlor], 46, is a lifelong “maker,” with a gamut of talents from electronics to optics to mechanical engineering. Aside from creating this giant walking machine, he restores
motorcycles
, installs high-rise fire safety systems and has built his own
laser
light show projectors. And perhaps surprisingly, he’s managed all this without a degree or other formal education, just an intense curiosity and unstoppable drive. We posed to him one of the most common questions we receive at
Ask HackADay
, as to how one can get started in electronics and building the sorts of
creative projects
regularly featured on Hack a Day:
Don’t be afraid of failure, it’s a crucial part of the learning process. Get your hands dirty and start building projects that interest you — build a model airplane, restore a motorcycle. By tearing it apart and putting it back together, you learn to see what makes it tick. Someone who’s brave enough or sometimes lucky enough to acquire the means to build something, they end up with a vast amount of practical knowledge about what they’re interested in. Textbooks alone can’t provide that.
Seek a lot of advice from people who’ve worked on this stuff before. Respect them by following through…don’t just talk about your grand plans. Go to Burning Man or Maker Faire or hang out with artistic people. This will bring crazy ideas to the forefront. The amount of influence you receive from showing up at a place like that is incredible. It’s unstoppable, a really powerful force.
Maker Faire is just a few weeks away. [Lindz] ponders the explosion of parts on his
workbench
and floor, uneasy about the looming deadline. Can he pull it off and complete these upgrades in time? We’re firming up plans to attend the show and hope to provide our readers with updates of all the various displays, including Russell and — fingers crossed — his new face.

If you’re into ham radio and want it when you’re on the go
give this antenna mount a try
. [Cirictech] started with a design from the
November 2009 issue of QST
and added his own fabrication touches. Everything except the antenna itself is available from the hardware store for just a few bucks, and you should be able to complete this project in a flash. This makes us wonder what the antenna for the
47 GHz band radio setup
would look like.

The exposed connection could be a problem I was going to put a connector on the vertical bracket but didnt have all the parts in my junk box so I soldered it in place and the connection have been sealed and hardened with epoxy and would take a large amount of force to break. This mount could easily be made with what ever terminating connect to mount any reasonable sized antenna. I constructed this mount and antenna with stuff I had laying around and at the lowest possible cost, as such there are many improvements that can be made. If you make one and choose to build it better or differently let me know and i’ll include it in the article.",

A wet strand of spaghetti is about the only thing that will resonate worse. Also when you do end up trying to match it, you have no more wire that you can cut away from the antenna since you are already at 1/4 wave, with the spare .25 inches in the bracket and embeded in epoxy. By running the wire through the padding on the door you elimiate the reason why someone would do a glass mount in the first place. Just because the padding is there, doesn’t mean it doesn’t compress and expand when the door is closed. The coax at that point is still getting compressed and released.The trick to keep mag mounts from scratching the car paint is twofold. Use a mag-mount with a rubberized base (or paint one on with liquid electrical tape) and take it off occasionally and clean the roof and the mount to remove metallic particles which will accumulate there. A mag-mount should get its ground plane from the ground on the radio chassis not from gouging a track in the roof.",

A bit light on the details, but we enjoyed seeing this
video out device for the Nintendo Game Boy
. A parallel cable connects to a modified Game Boy and transmits signals to the adapter which is housed in an old VHS cassette. We gather that some Super Game Boy hardware does the signal processing but from there your guess is probably better than ours.
[NeX] mentions that he originally wanted a screen to be included in the cassette. We’ve seen custom
portables with small screens
before, but he’s also developed
a bare bones hand-held without a screen
so that’s where the inclusion in the cassette would have been handy. We also wonder how the images will look on a big TV of the 50+ inch size. [NeX] has been pretty busy with the hacking lately, don’t miss the
wire porn
of his
homemade Game Boy project
.
[Thanks Jose]

He’s just hooking wires up to places they were originally meant to go, but in a slightly different package than the Game Boy itself.The Super Game Boy is essentially just a Game Boy CPU and cartridge connector in an SNES cartridge. All he did was wire the pins from one Game Boy’s screen to the pins from another Game Boy’s screen.The “Modular Game Boy” is just a Chopped down PCB with a DB-25 connector sending the pins for the missing functionality to other devices (which do nothing but perform the same function, mind you), when the functioning hardware was already there. Anyone could have done it, but nobody did because it’s basically useless. Maybe it’s a fun project for someone to play around with, and I don’t blame him for doing it once because he had a broken game boy, but there;s no use for it.The video out, okay. I can see how that could be advantageous in a live performance setting where one would want his own screen to fool around with LSDJ while on stage as well as let the crowd see on a projector or TV.But please. This isn’t the second coming of Jesus.If I cut all the traces from my Game Boy CPU on the PCB, then soldered wires directly to the components that those traces go to from the CPU, no one would be impressed. You’d tell me to fuck off. But if I then took the PCB away, apparently I’d be a god among men.",

Thus, when played on the SGB, it’s all tuned up and the right speed. The very same reason it doesn’t speed up to around 200% and raise one octave when played on the CGB. =]Though you are correct, the SGB isn’t perfect. In my experience, the main difference (possibly just in LSDJ though) is the way it handles legatos, pitch bends, and vibrato. It doesn’t seem to know when to stop changing the pitch.That said, even the CGB is a little bit off (too much for me). I’ve found that all of my CGBs skip around 10-40% of the notes played in their noise channels. Not a good thing for music. Though again, I have only really bothered to test with LSDJ, so it could be a problem there.The gist of it: DMGs are just the superior Game Boys.",

"content": "Chris, you really seem to have an axe to grind. You (and others with similar comments) seem to think that something shouldn’t even be posted on the Internet if it’s not up to your exacting, ill-defined standards.I have an idea. Let’s define a standard for Hackaday project postability:1. LED Hacks – NOT OK! LEDs are stupid, only require connection to DC voltage, and are certainly not worthy of being called “hacks.” However, as the number of LEDs increases, the project’s worthiness increases proportionally. Note that any use of charlieplexing, however trivial, makes an LED project OK to post, and in some cases “Awesome.”2. Nixie tubes – OK! Automatic front page. Because in Soviet Russia, decommissioned outdated hardware is sold to you! Plus, they glow and are not LEDs.3. Steampunk – OK! Hey, it’s fucking brass! Brass screws and pipes are what butters Hackaday’s bread.4. Resoldering and PCB cutting – OK, unless you’re doing something that SOMEBODY ALREADY DID ONE TIME SOMEWHERE, OMFG. Also, if you have not done something sufficiently awesome with it (as defined by the afterpost comments), most definitely NOT OK.5. Arduino (PIC, et al.) Projects – OK, but it had better DO something, or it’s a WASTE of an Arduino. The Arduino is endangered, so you can’t just buy as many as you want, to do any THING you want with. Also, if at any time the number of Arduino projects posted in a given week exceed an arbitrary number (usually 5 or 6), then Arduino is definitely NOT OK. Find another project to work on! And FFS, DON’T POST ABOUT IT ON THE INTERNET, at least until the number of Hackaday posts about it decreases.Please try and remember that these projects are not SUBMITTED to Hackaday. The Hackaday editors go out and FIND this stuff. If you really think it’s that bad, write an email to Mike Szczys and tell him you think his taste in hardware projects sucks. Also, tell him why you think it’s an easy, stupid, useless project. Because I certainly don’t want to hear it.Oh, and, “nobody did because it’s basically useless.” Welcome to Hackaday.– Mike (not Szczys (holy crap, that’s a lot of consonants))",

I figured that implied that he sent Hackaday a link to this project.@NeX: Regarding trying it myself, I’ll give it a shot. The main problem I have is getting my Super Game Boy open without damaging it (I don’t have a gamebit) because it’s a BRAND new one (not even marks on the pins) and I’d rather not damage the case.I’m not trying to say you shouldn’t have tried this, or that it’s total crap. I did say that some of it is ostensibly useless (which I still kind of feel) but that’s not to say it’s a total waste of time. It’s good to work on projects, and it feels great to finish them, even if they’re blinking lights in arduinos (@Mike #1). But I’m just rather annoyed at how crazy and amazing everyone — on 8bc especially — seems to think this stuff is. I’ve been rather rude about it, and I apologize for that. You did a good job on it, accomplished your goal, and kept it tidy. I think this has a lot of potential to be a lot more (less, as the case may be) than a Super Nintendo and Super Game Boy crammed into a case. Please correct me if I’m wrong about what it is.If you take the knowledge you gained from this project, and put it towards the more daring project of getting this functionality on a small board with a microcontroller or something on it, and use all of your own design instead of already-working hardware, I will be the first one to shake your hand… over the internet… and say it’s worthy of applause.I did go overboard trying to illustrate my point, there’s no denying that.

[Knuckles904] was tired of waiting for the bus. His town had installed GPS units on the buses so that riders could track their locations via the Internet so he knew there should be a way to avoid the wait while also never missing the bus. He developed a sketch for
an Arduino to check the bus location
and notify him when it was on its way.
This method saves him from leaving his computer running. It parses the text data from the public transportation website and updates both an LED display, as well as a Twitter feed. Now he can monitor several different bus lines via the hardware at home, or though a cell phone if he’s on the go.

The Warthog from Halo is one of the most beloved video game vehicles. [Tim Higgins] brings the fun to life with his
laser tag Warthog game
. It uses Barbie Power Wheels toys as a base and adds laser tag weaponry. Xbox 360 controllers are used but just like in Halo, you can’t control the gun and the vehicle at the same time. We’ve encountered [Tim’s] love for
water-based amusement
before and this did originally start out with a water cannon powered by a wind-shield washer reservoir.
Take a look at the videos after the break as well as
his recent post
for information about the hardware. His choices for controller circuitry are way overpowered, sourcing an Eee PC to do the heavy lifting. This is because the choices he made were for easy development and not economy of components. A PC has no problem connecting to Xbox 360 controllers, and the modular control boards mean no complicated circuit design or arduous soldering were necessary. In the end, this looks like a ton of fun and we give him bonus points for repainting the pretty pink plastic that comes standard with these models of children’s toys.

When you got 3 functions disabled, you lost and the car’s alarm went off flashing a red light.

Force Feedback For The Nintendo DS

This cool mod brings
force feedback to the Nintendo DS
. There’s a motor with an offset weight mounted inside the DS for vibration and some nice SMD LEDs plopped in there for good measure. The force feedback is being controlled via a picaxe mocrocontroller and triggered from the analog audio signal. While using the analog audio may not be the most precise method, he says that the results are pretty decent.

Need to monitor not only if a fan is running, but if it is running fast enough? Check out this
PC fan failure alarm circuit
. After several failed attempts using
various circuits
, they settled on a
Schmitt trigger
. They even show a couple variations including a manual reset and a relay instead of a buzzer.

Finally a voltage comparator with a feedback circuit for hysteresis compares the voltage across the capacitor with the preset value.The only thing I don’t really like about it, is that it depends on the value of the decoupling capacitor and the transistor base current (which could use a resistor, btw) to get a slowly rising average voltage across the filter capacitor when the fan slows down. Since the duty cycle is fixed, the voltage across the decoupling capacitor needs to increase to Vcc-0.7 to get the transistor to close completely. This means it’s not entirely independent of the input frequency, above a certain frequency, the voltage across the filter capacitor won’t change any further.I don’t see an easy way to fix this without adding quite a few components.It’s useful for monitoring fans in things other than computers, and it’s a nice circuit for teaching things like hysteresis and low-pass filters.",

Sure, tearing down devices to see what components are in there is fun. But tearing down the components themselves is even more fun. iFixit
sent off their iPad guts to be laid bare
after they were done with
their iPad teardown
. We’ve seen
pictures of stripped chips
in the past, but
the work that Chipworks is doing
for iFixit is quite amazing. Get the skinny on just about every part in there from the package markings and the die photos provided in their analysis.
The
iPad has already been rooted
, but you never know what power can be unlocked if you know what you’re working with. We’re thinking of the 50MHz to
100Mhz oscilloscope hack
.

Solenoid Motor From A VCR Head

Here’s
a solenoid motor you can build from a VCR head
and some common components. It uses an LED and a light sensor, paired with an LM311 comparator to manage the switching of the motor. As the head turns, the LED shines on the sensor through a hole and triggers a TIP120 transistor to turn on the motor during the power stroke. Once the beam of light is broken, the transistor turns off the motor and the momentum carries it through its revolution until the next power stroke is activated.
We often say that “why” is the wrong question. [Bd5940] must feel the same way because he ends the video by saying: “it has no use, but definitely a conversation piece”. Yep,
we’ve seen that before
.

[Michael] designed this display board to mimic the appearance of a police car pulling you over. It resides in the rear window of his car (facing forward) as
the controller board measures the speed of the vehicle
. An Arduino grabs NMEA data from a GPS module and compares it with a table of speed limits. If you are speeding, based on your current location, the reds and blues flash as if you’re getting pulled over. The thrill of getting busted for a lead foot doesn’t sound like much fun to us but to each his own.
Incidentally, [Michael] is using the EM406 GPS module, the same one as
the Frustromantic Box
used.

Personally, I like it, especially if it was made completely portable and you tossed in the back window of a buddy’s car; as soon as it went off, his first reaction would be to hit the brakes, dropping his speed and turning it off. This would probably happen fast enough that he would have already dropped back below the limit before he had a good look in his rear-view mirror…where no patrol car exists. He would most likely catch on after a couple of times, but, until then, a hidden dash cam would make for an /awesome/ YouTube video!",

Beginner Concepts: Electronic Jack-in-the-box

Behold the
electronic Jack-in-the-box
. Open the lid or enter the wrong combination and you’ll set off an alarm. But if you get the right 6 combination code entered using the three buttons you’ll be rewarded with a little ditty and the appearance of the Jack (who lives in the box). [Jeremy Blum] designed this as part of his
introduction to rapid prototyping class at Cornell University
. See his description of the project after the break.
When he shared the link with us he mentioned that this might be a fun project for beginners and we couldn’t agree more. The design is easy to wrap your mind around using the provided
schematic
. The source code package includes PDF files that contain well commented code segments along with their descriptions. You can use this to get comfortable with driving a speaker and servo motor using an Arduino, as well as to read from two different types of inputs. We are especially interested in the hardware debounce implemented for the switch that detects if the lid is closed. Software debouncing is pretty much the standard these days but because an external interrupt is used to read the switch that method won’t work here.
If you’ve got an Arduino and few of these components why not give this a try?

Internet Radio Player Wins Propeller Design Contest

It’s got a NIC, a remote, a character display, and can record and play back streaming audio. Thumper is [Harrison Pham’s]
contest-winning Internet radio player
.His finished board is roughly the same size as the 16×2 character display and piggy-backs the device for a small form-factor. It can be controlled via an infrared remote control, or through a remote web interface. Source files are available from the link at the top, but the really juicy details are included in the shockingly comprehensive
PDF writeup
.
The photo above is a bit misleading. The board has a micro SD slot on the back even though a USB card reader is shown. This project would need
USB host control for Propeller chips
in order to use that reader. Don’t forget to check out some of
the other submissions to the the contest
once you’ve had your fill of this one.
[Thanks Drone]

Program Your Own Mayhem-causing USB Dongle

[Adrian Crenshaw] is up to no good with this
programmable USB device
. [Adrian’s] creation identifies itself as a USB keyboard and can be programmed to do whatever you want. That’s because it’s based around the
Teensy
board which sports an ATmega32 that will cost you only $18. He’s added a set of DIP switches for easy in-field changes to the firmware. There’s also a light sensor that can be used to activate a command once an unknowing victim has shut off the lights in the office and left for the day. Check out his talk after the break to see his proposed uses for such a device.

This
somewhat frightening armature
is the base for the iconic energizer bunny. While we love seeing the guts of popular robotics, this brings up an interesting fact. In Europe, the bunny is the symbol for Duracell. There’s an interesting story where Duracell had used the bunny for years in europe, only to inspire Energizer to copy them stateside in 1989. This one will be available on ebay shortly.

The director yelled ‘cut!’ but the bunny kept going, and started plowing through “other commercials” which were being shot at the same time in the same studio. You would see ads ostensibly for some long distance service, and the bunny would plow through and knock over the divider in the middle of the screen between ‘here’ and ‘there’ – that kind of thing.",

Project J.A.R.V.I.S.
is an attempt to create a digital life assistant, or DLA. The name comes from the version in the movie Iron Man. While the details of the build are pretty slim, you can see that he’s using a mac mini for the base with an Arduino controlled RFID reader at his door. What is really interesting is how functional he has actually made it. Watch
the video
on the site to see a pretty good explanation of features.

I imported the Predator film script which caused some language problems but was funny to hear random movie lines from Predator in convo. I would encourage others on HAD to check it out and see the results. My first speech program (dragonsoft) I modified in a Navy sort of way to listen with the mic at the window and type Ford F-150 when that truck came to park in my parking lot. I think there were 10 cars “programmed” that way and two dogs that lived in the complex. It was more of a proof of concept thing in ’99 but my Instructor ended up getting a meeting with a Colonel and he liked the simplicity lol. Never heard naything else (because it was a lame project) but may give some of you other ideas as to what you can do. My Ultra Hal hears the sputtering of the coffee maker in the other room when it is at the end of making and will say “coffee’s ready if you are” It is simply a matter of getting it to “listen” to the sound and create an event from that. My wife thinks it is weird so I kinda have to work with it when she isn’t around to laugh at me talking to a half literate computer lol.-I know- Cool story bro…",

Go to DeviantART and search in the box: ‘Rainmeter’ (without the quotes)3. download a few skins and try fusing them together to form an ironman skin… see what you can come up with…4. try to obtain a windows sound pack based on the voice of JARVIS. This shouldn’t be too hard…At the moment, my laptop is being fixed, so when I get it back, I will make a screenshot of my JARVIS rainmeter theme.

Until I can figure out how to make it more intellegent and get it to read out feeds and weather, mail messeges, i’ll just play with this version.“jarvis open skype and call Mark” — Jarvis say’s “Very well sir, opening Skype and calling Mark Smith”. – it even does it which is cool, but it requires a back up from speach rocog to choose the call setting.“jarvis, open weather” — Jarvis say’s “very well sir, bringing up local weather details in our area” – brings up a page for weather for where I liveand my favorite so far.“jarvis, open media player and play my ironman playlist”.opens windows media and plays the song selection.I might add variations of each question so that if i come in and say jarvis playlist 1, it will do just that.I’ve zero programming experience but it was just fun to hear the laptop talking back.anyone know an easier way of getting it to call someoen just by saying call jack or whoever?",

Teletype Twitter Frontend

The folks from NYC Resistor got their hands on
a teletype machine and hacked it to monitor Twitter
. This eighty-year-old beast bangs out messages that it receives at 45.45 baud. This isn’t a project that
turns something into a teletype
, but rather finds a different way to feed the machine data. In this case, a python script parses Twitter and sends the data it finds to an Arduino board. The Arduino in turn formats the message into the serial format necessary to communicate with the device. To the left you can see a trend plotter, learn more about both in the video after the break.

The arduino bootloader and IDE makes developing the firmware painless.I agree that the atmega168 or atmega328 is overkill. But then again, this project wasn’t to make the most technically perfect interface for the teletype. It was to repair the teletype and hack together an interface.

Look at the spd_cust option here:http://linux.die.net/man/8/setserialThen you use stty to set the terminal to 5 data bits, two stop bits (which is close enough to the 1.5 stop bits normally required).Then you just have your Python script convert ASCII to Baudot and send it to the serial port as normal.

Fully-automated Golf Ball Gun

"launcher",
"spud gun"

If you get in the line of fire this
golf ball launcher
is gonna leave a mark, or worse. It’s based on the same premise as
the sausage gun
, but now everything is automated and no meat products are used.
A hopper stores a row of golf balls. When it comes time to load, a ball falls into the chamber, starter fuel is sprayed into the combustion area with the aid of a fan, and after both chambers are sealed the propellant is ignited.
We’ve embedded two videos below for your amusement. It looks like [Chrille] and his friends are being careful with their creation. We’re glad for that because this is about as dangerous as the
high-velocity ping-pong ball launcher
.

Logic Clock Without An On-board Oscillator

"50 Hz",
"ac",
"clock",
"frequency"
] |
[Lucassiglo21] developed
this logic clock
without using a crystal oscillator or a resonator. Instead, he’s letting the incoming electricity keep the time for him. The supply is AC at 50 Hz so he’s using some 4017 decade dividers to reduce that down to a 1 Hz signal. From there it keeps track of the ticks just like
the last digital logic clock we saw
.
If you’ve used AC line frequency as the clock source in your project we’d like to hear about it.
Send us a tip
and make sure your writeup includes a schematic. We’re especially interested to see if anyone has a good way of using this method with inexpensive microcontrollers.

"content": "@DavidShort-term average power line freq stability is OK. Long-term average power line freq stability is excellent.From wiki:“Regulation of power system frequency for timekeeping accuracy was not commonplace until after 1926 and the invention of the electric clock driven by a synchronous motor. Network operators will regulate the daily average frequency so that clocks stay within a few seconds of correct time. In practice the nominal frequency is raised or lowered by a specific percentage to maintain synchronization. Over the course of a day, the average frequency is maintained at the nominal value within a few hundred parts per million.[17] In the synchronous grid of Continental Europe, the deviation between network phase time and UTC is calculated at 08:00 each day in a control center in Switzerland, and the target frequency is then adjusted by up to ±0.02% from 50 Hz as needed, to ensure a long-term frequency average of exactly 24×3600×50 cycles per day is maintained.[18] In North America, whenever the error exceeds 10 seconds for the east, 3 seconds for Texas, or 2 seconds for the west, a correction of ±0.02 Hz (0.033%) is applied. Time error corrections start and end either on the hour or on the half hour.[19][20] A dynamicdemand.co.uk/grid – Real-time frequency meter for power generation in the United Kingdom is available online. Smaller power systems may not maintain frequency with the same degree of accuracy.”",

The turbine/generator would be spun up first. IIRC: The generator is spun slightly faster than the grid frequency. There is an analog dial right on the outside of the generator housing that spins in relation to the difference in phase between the generator and grid. When closing the breaker, the operator had to look at this dial and flip the switch as the needle approached a mark that indicated phase-sync. Failing to do so would result in the generator and turbine immediately moving in phase with the entire grid – meaning goodbye turbine building.

Here is
something we didn’t expect
(NSFW). The machinima crew behind
RedVsBlue
, Rooster Teeth, actually did a hack!
The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.
What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might
we suggest processing
). Oh dear lord, is the world ready for this!?

Reminds me of the vertical tail wing cameras they install on Airbus A380s! There’s a very cool view from them!.There were several things I kept having to do when playing GTA4 –1-Use reverse view for awareness of surroundings, esp. for whats directly in front of the car. But adding this ability to their rig would double their costs at least!2-When driving fast its important to see from a higher perspective to get a greater idea of whats in front; I’d hold the camera control thumbpad up a little as I drive fast so I can just see the horizon at the top of my TV. Alternatively I’d have preferred it to default to a much higher perspective and thats what they could have done to improve visibility, at the risk of overextending the boom with the expensive camera!",

[Riley Porter] has been working on several different custom enclosure designs. Above, you can see his
Proto Desk
which holds a breadboard, Arduino, and has two recessed boxes with sliding tops for components and patch wires. He’s got
a miniature version
that gets rid of the breadboard, as well as slick-looking cases for the
Bus Pirate
,
tinyISP
, and
face plates for word clocks
.
Well, if you’ve got a laser cutter you should be using it right? We’ve seen [Riley’s] wares in the past; he wrote
the guide for laser cutting solder stencils
.

USB Host For Propeller Micros

[

[Micah Dowty] has implemented
full speed USB host control on a Propeller microcontroller
. He’s motivated by the thought of using USB based WiFi and Bluetooth dongles in his projects as ready-made solutions.We’ve seen
USB host control with the Arduino
and it really opens up the flood gates for advancing your projects through storage, wireless connectivity, and user interface.
So far his work is fairly preliminary but the results seen from other participants in the Parallax forums are very positive. Check out his code from
the subversion repository
and lend a hand with the development.

When doing those cool liquid droplet splash pictures, you need to time not only the camera, but the droplets themselves. This project takes you through how to
build the system to time the droplets
and work with
camera axe
to get the right pictures. PCB files and schematics are available. As you can see, the results are quite nice.

The artistry is in how you are able to get your subject to stand still for hours while the exposure is taking place.",

JooJoo Turns Out To Be Legit, Gets Torn Down.

The
JooJoo exists
. With all of the recent media coverage of the iPad, we’ve had a chance to hear some interesting discussion and heated debates. Usually the more tech savy and the hackers are most upset about the “closedness” of the hardware and software. We have heard of many alternatives, but usually they’ve been pretty clunky. The JooJoo(originally “crunch pad”) by
Fusion Garage
gets mentioned, but we’ve been avoiding it since the company had been having so many set backs, we doubted it would actually exist. Well, it does. The shipped the first ones at the same time as the iPad.
What is so special about it? well, heres what you’ll find when you open it up (yeah, with screws).
a RAM slot, 1 GB provided
2x mini pcie slots
1x ssd slot
a 3g sim slot
Nvidia’s new ion graphics chip
An atom n270 processor
With 4 Gb of storage, bluetooth, wifi, a
camera
,
external USB
ports, a screen boasting 1366×768 resolution, and a slick interface which
supports flash
, we can’t help but get excited. It costs $499. We think this could be a fantastic hacking platform. We aren’t going to just run out and buy one yet, but if it takes off, we expect to see people hacking these like crazy. Too bad they couldn’t have gotten a little more press to compete with the iPad.

(Apps that anger apple are ones that they wont let in the apple store.)I honestly believe that ANY of these products that sell for more than $99.00 is a rip-off. but I’m biased against overpriced hype that people fawn all over for no real reason. This JOO JOO pad is a useless piece of crap as well. And those of you screaming “put linux on it” do you even know linux? Linux SUCKS for tablet use. I know, I have screwed with it in tablet form for over a decade, and I have used tablet pc’s for nearly 20 years. (Dauphin DTR1 was the first tablet pc, and I had one, suck it bitches!)Linux has no useable tablet support. so quit spouting about “put linux on it, put linux on it” why? to make it unuseable? If all you kids in your mom’s basement want a linux tablet so bad, go on ebay and buy a old fujitsu for around $200.00 and put linux on it and maybe use your 7113 skillz to make it tablet ready… Oh wait, most of you dont have $20.00 to your name so $200.00 is way out of your reach…sorry for the rant, but most of the losers here really piss me off. “Ipad sux!” from someone that has never touched one makes them a raging joke loser. I have touched one and used it for about 1 hour. It’s neat, but overpriced. JUST LIKE THIS JOO JOO pad. when the identical product has the same price comes out, it’s not impressive to anyone, yet the anti-apple-fanbois (typically dirt poor posers that wish they could afford apple hardware) shoot off their mouths.Stuff it posers. This pad is crap, just like all the other ones that already exist and will ship over the next year or so.",

Its been quite a while since we’ve featured something from iFixit. But when we saw they had torn apart the next greatest Apple product,
the iPad
–
released today
, and how everyone on
our team
loves
it
, we thought why not also let our user base enjoy the
destruction
informative teardown as well.
In both the original and the
FCC teardown
, we see some awesome features and tricks Apple implemented. Most notably the two separate 3.75V lithium polymer cells, not soldered to the motherboard, allowing users to easily replace the battery if need be. However, in the opposite respect, more components than ever are being epoxied to the board, making the iPad much more rugged.
We’re left wondering, with everyone able to see the beautiful insides, does it change anyone’s mind on getting an iPad? Or would you rather
make your own
?

If you want to watch movies or surf the web on a moderately-large screen (compared to a phone), you’ll likely get a netbook or laptop. If you want the apps and whatnot, why not get the iPhone for superior mobility – or better yet, get the Nokia N900 and use your device the way you want?My projection: the iPad will be Apple’s Virtualboy – neat idea, poor execution.",

It is refreshing to read comments by people who know what they are talking about, and who have somehow managed to avoid becoming infected by the Apple Virus that appears to be making mumbling Zombies out of people who otherwise are perfectly reasonable beings.As has been pointed out by most of you, this is a machine that costs a small fortune, and apparently, apart from its box is actually much less than any other computer that has ever been put on the market by anyone… for a fraction of the price of this device.And yet, and yet…… It sold out within minutes of going on the market we are told.Come on you guys, here is a challenge for you from me…. Hack an iPad into something useful, and then post your work here for me, and the rest of us to admire…….And if you can hack it into a really usable eReader, then I will certainly write a post about it for my Blog, with real pleasure!",

However, their use will probably begin to be limited to times I know I’ll have a place to set them up and use them comfortably.My laptop is too big to actually sit on a lap so that eliminates portability. Even my netbook is too bulky for comfortable use unless I can set it up on a table. The iPad gives me back that portability and the touch screen interface has it all over my mouse (God, I hate touch pads).So as it breaks down, I’ll be using the PC/laptop/netbook if I’m going on business or have significant work to do. The iPad will probably end up being used as a peripheral to support them (entertaining myself with portable music/video, taking notes, working on simple documents that I can later sync to the desktop, presentations to clients).I believe it’s ultimate acceptance will not be determined by how “pretty” it is or even it’s price. It will be determined by how well it integrates into people’s lives and to a large extent that will be determined by ease of use and the applications.",

Touch Screen For Graphing Calculator

[Owen] got down and dirty by
adding a touchscreen to his TI-84
graphing calculator. The dirty part is the z80 assembly code he wrote to use the linkport as a UART (assembly always makes us feel queasy). Once that was working he implemented some commands using an Arduino and then hooked up an Nintendo DS touch screen. Now he’s got this proof of concept video where he draws on the screen, that input is interpreted by the Arduino, commands are sent through the UART, and the calculator program draws on the screen.
Adding a touch screen to something
is a lot more impressive when you have to go to these lengths to get it working. Nice job!

HDD Power Tools: The Sander

At first we thought this looked hastily thrown together and quite possible useless. Then we watched the video, embedded after the break, and realized it is quite
a handy bench sander
. [Mhkabir] opened up an older hard drive, removed the read head, and added a piece of carefully cut sand paper. When you hook it up to your bench supply you’ve got a small sander ready to use. We can’t wait to try it on some small PCB edges. Now that we’ve seen a sander and
a chop saw
, we wonder what’s next?

At least it’s what *I* feel separates Hackers from mundanes- and Hackers needing to think before disrespecting.We tend to be immediately mumbling “Where did I put that box of old HD’s” instead of Peanut Gallery heckling every freckle on the latest HaD featured Hack.Yes- there’s always valid Constructive Commentary to be shared and even welcomed.

There isn’t much torque, so I think there are better solutions out there for doing any kind of sanding work, but for finishing a blade it’s fantastic.@ Oren Beck: “The mundanes…”Way to reinforce the elitist nerd image.

Any of you that have ever ever experienced a head crash on a hard drive, and taken it apart to see the damage can relate. Also please keep in mind how light and flimsy the head is in a hard drive. Check out the link below to see what this flimsy little head can do to a hard drive platter, then imagine what it would look like if you actually applied force to the platter. While the platters in your hard drive may seem to be really hard, they weren’t engineered to have any friction applied to them. Do you really want to take a chunk of a HD platter in the face, or even hand for that matter? I’m done with the soap box, and now for the link to what a flimsy drive head failure can do to your new sander –http://gfx.ibas.com/news/pictures/total_head_crash.jpg",

There is no where near enough kinetic energy in the platters (low mass, low torque) for that damage to occur immediately.That damage is caused by a head coming UNGLUED from the arm, and then the arm abrading away at the platters for 100’s of hours. Not split seconds, seconds or minutes, but hours and hours.You see drives like that NOT from homes where a damaged drive is immediately apparent, but from multi drive raid arrays where a dead drive may often be left running for extended periods before being pulled from service.I have one in my drawer here at work still. The admins said the drive was noisy for weeks before it fell silent.CheersJacob",

This clock requires no microcontroller. It’s actually a
digital logic counter that functions as a timepiece
. [BlackCow] used six decade counters to track seconds, minutes, and hours. The output is displayed on four 7-segment digits using BCD-7-segment decoders that you can learn about in
our binary encoded decimal post
. The actual timekeeping is done by a quartz clock circuit he pulled from a Mickey Mouse clock. This would be a perfect circuit to build in a
digital logic simulator
, just
follow the schematic
and learn as you go.

Update: This How-To was written for April Fools’ Day. It is not advised you attempt to make or even use this cable. The comments have made it very clear how dangerous to you and others using this cable can be. The image above is not of a full male-to-male cable, only the ground is connected, and the generator is not running.
We all know Ethernet has the crossover cable, cars have jumper cables, and RS232 has the null modem. Well, it is about time our wall sockets get their own crossover cable. This crossover cable is great for running power to a circuit disconnected from power. Maybe you are out of fuses, the breaker is broken or you just don’t want to go check the fuse box when there is a murderer about. This cable makes a great gift for even the most loathsome of acquaintances.
This an April Fools’ Day post. You should not do this!!!
Warning: These are Mains voltages and currents we are working with. If you do not know why you should not attempt this, you should not attempt this.
You will need:
1 Extension cord.
1 Male extension cord repair connector.
Tools to strip the extension cord, and attach the connector: Knife, wire strippers, and screwdriver.
Respect for mains voltages and currents.
If your extension cord has warning labels, read them.
Cut the extension cord to the desired length.
Strip about one inch (2.5cm) of the outer insulation from the part of the cord that has the male plug.
Strip about 3/8 inch (1cm) of each of the conductors. If there is a strip gauge, use it for a guide instead. Twist each of the stranded conductors to prevent fraying and possible shorts later.
Slide the shroud over the cord.
Screw the conductors into each of their respective terminals on the connector.
The Green or bare conductor goes to the ground conductor terminal. It often has a green screw.
The White conductor goes to the grounded conductor terminal. It often has a silver-colored screw.
The Black conductor goes to the ungrounded conductor terminal. It often has a gold-colored screw.
Use a multimeter to check continuity and make sure there are no shorts.
Slide the shroud up to the connector and fasten the two parts together.
Secure the cable clamp.
There you have it, a finished Mains crossover cable.
There you have it, a Mains crossover cable. How might you use this crossover cable?

Core3Duino (April Fools?!) And XDuino

It’s inevitable. You knew it, we knew it, and while this is being posted on April 1st; its no joke. [johndavid400’s]
Core3Duino
. As we
mentioned before
, with the additional Arduinos you have now 3 separate processors, allowing 24digital IO, 18 PWM, 18 analog inputs, and more.
Now to keep flamers at bay (
calm down
), we’ve combined this post with the introduction of
xDuino
. Yet another attempt at
porting Arduino
to separate hardware platforms. For the price of a Duemilanove you can have 5 serial, 48 IO, 18 analog, 68Kbytes of Ram and more!
[Thanks Kamil]

Get a quick fix of CNC for the day with
this plotter
. [Francisco Dulanto] grabbed the cartridge carriage from an old inkjet printer and turned it into a gantry by mounting it on two drawer sliders. The optical head assembly from a cd-rom provides the Z-axis movement with the whole thing controlled by three RepRap boards. [Francisco] called his project a joke compared to
the Turing Machine
, but we like it and we’re glad he
tipped us off
. There’s something zen-like about the projects that are thrown together with what you have available. After all, he’s certainly achieve a clean-looking build that does what it’s intended to do.

Sony Removes PS3 Linux Support With An Update… Errrrr, Downgrade?

Sony is rolling out a
firmware update for the PS3 on April 1
but we’re pretty sure it’s not a joke. What we’re not sure about is that you can call it an update. It removes features rather than fixing or adding them. In this case, it is removing the “Install Other OS” option that allows you to run Linux on non-slim versions of the PlayStation 3. It is fairly obvious that this is a reaction to the hypervisor exploit that was released back in January that breaks down the machine’s security barriers.
[Geohot], the guy who found and release the exploit,
published a post on his blog
expressing his disapproval of Sony’s actions. We’d have to agree. It’s pretty cold-hearted to remove functionality that was advertised with a product. We’re sure there are many folks out there using the Linux support who have no interest in exploiting the product. This is gardening with a backhoe and quite frankly it stinks.
This may bring on a torrent of
new effort in unlocking
and laying bare the PS3. If so, doesn’t Sony deserve it?

Sony routinely shits on its customers and has had a history of doing so.So, yeah, eventually a company can alienate its customer base and hurt themselves in the long run. If you advertise a feature of hardware now and take that feature away later with a software upgrade then why should your customer believe you won’t do the same in the future for some other product you buy from them?What if Sony decided that your DVD player should no longer be able to view any DVDs but Sony DVDs? They could make the claim that it’s to prevent piracy (and Sony DVDs do routinely include anti-piracy features), but how would you feel about losing the ability to view some of your DVD collection? They picked on Linux geeks this time, so they only alienated a small portion of their customer base, but that eventually adds up if the same practices continue.",

There’s a reason that a ton of players of MMOs, for example, swear NEVER to pay Sony a subscription fee for any MMO ever again. There’s a lot of venom toward Sony’s policy of doing whatever the hell they want; the customer be damned.I’m not surprised about Apple products not getting many complaints. Apple could do the exact same kind of thing that Sony did here and their customers will say “thank you, may I have another?” It’s unusual for a company to have such a hardcore fanboy base that they can almost do no wrong, but Apple has achieved exactly that.It sometimes seems like everyone hates Microsoft all at the same time, yet they still dominate the market. It’s interesting how two companies can have such radically different consumer groups though they essentially sell the same thing.",

"content": "I got my PS3 at launch, paying over the price to get it early. The first thing I did was install a bigger harddrive and install Linux. Both being almost encouraged by Sony in their press releases and manual. The Linux system was disappointing because of the lack of RAM and limited framebuffer video, but it was a start. I hoped they would give us a proper 3D driver, particularly as the machines video is supposed to be based on Nvidia who already have a driver for linux. But no, it was to never happen.The PS3 had the chance to be an excellent media center, but Sony can’t see beyond their awful interface and poor codec support. Sometimes m2ts files would play, an update later they wouldn’t. DTS support went AWOL for a number of “updates” too. The US PS3 won’t play region free PAL DVDs yet The Euro one can handle NTSC, and the Divx official support turned out to be worse than the unofficial support on the 360. Again, a minor step in the right direction, but then nothing.They removed SACD, something they surely own, so how can the lose money by supporting it.Sony needs friends, they’re going down the pan year on year. They’ve got the hardware, no doubt about that, but the corporate attitude stinks. Just open it up and let the fans and market make of it what they will. A open system will sell.I shall not being doing the update, that means no online purchases from me anymore, no testing games via demos, and I guess at some point new games and blu-rays will stop working on it, requiring a > 3.15 FW. That’ll be the end of my PS3 game purchases when it does. blu-ray players are dirt cheap these days, so buying another or hooking up my laptop isn’t going to be the end of the world.Meanwhile, I’ll get the usual candidates like MW3 or whatever for our 360 instead. I prefer the PS3 controller, but Sony have decided they’ll annoy people like me, I’m happy to let another company take my money instead.I feel sorry for those that have missed all this downgrade news and will let their consoles update as if it’s another update, only to find they’ve lost their Linux system the next time they try to use it.As to the security excuse, hardly, even season modders have nothing to work with. Hasn’t anyone else noticed how hypocritical this is coming from the company that brought you rootkit music CDs.",

Sell the console at a loss to make tons of money on selling games for obscene prices.That’s not to say that I agree with what they’re doing. Far from it. I think they are vastly over-reacting to the whole exploit game. Yeah, you may eventually be able to pirate games, but I think the number of people who do that is going to be so small as to be negligible. To make a copy of most games you’d need a blu-ray burner, and blu-ray discs, at which point you could have bought 3-4 games.Sony did the same kind of things with the psp, and it hurt them. Sony should have seen the potential for homebrew on the psp, embraced it, and supported it through an online store portal. I think most people will see the analogy i’m trying to make here (app store). This could have been done years before apple, and hell, the psp is still getting awesome homebrew and games.Sony needs to realize that there are more options than hurting their customers and having pirated games. If the opened it up and encouraged homebrew, they could create an environment in which they would be able to offset potential loss from pirating by profit on user created content.

They always re-release-re-release the same hardware on 1 platform, I don’t see why they would care about the fat ps3 as they are now discontinued.

Tired of every printed circuit board you etch coming out brown? Take a page out of [Dane’s] book and
dye your PCB to just about any color
you want. One hour submerged in a 200 degree bath of
Rit dye
turned his brown
FR4
substrate to the desired dark green. We give him points for being dangerous enough to use a broken bottle as a vessel, yet wearing eye protection at the same time.
We never really thought of doing this, but it’s pretty interesting that it works. We’ve stained the substrate when
removing etch resist
so this should have been obvious, but wasn’t.

Update: 50MHz To 100Mhz Scope Conversion

Changing this 50MHz Rigol oscilloscope into its larger, more expensive brother
just became quite a bit easier
. When
we originally looked at this hack
it required pulling some capacitors off of the board. Now all it takes is three commands over a serial terminal connection.
Take a look at the walk through video after the break. You’ll see that there’s one chip that needs to be setup differently to change the functionality. Removing capacitors was actually changing the commands sent to initialize that chip at power-up. Now you can just change the model number and one letter of the serial number via a terminal and the firmware will recognize this as the more expensive DS1102E.

You’re paying for the IP that goes into developing the hardware and software these days, not the hardware itself – that costs next to nothing. You also run the risk that although they may be manufactured on the same production line, the lower spec models are lower spec for a reason; maybe they don’t meet the tolerances that’s expected of the guaranteed parameters of higher spec models, so although they might go up to 100Mhz, and may even do it accurately, you have no guarantee that it will be as accurate as a scope with the 100Mhz firmware. So you can do it, but at the risk that it may not be as accurate as you expect it to be at higher frequencies. Of course, if you just want extra functionality and don’t need a high speed ‘scope, then a hack like this is the best of both worlds.",

When possible companies design boards that can be used to build different models so they get heavy discounts by ordering great quantities of the same components and/or by resorting to as few production lines as they can.Sometimes they just don’t add the components of the bigger models so you see empty spaces on the board (just open your PC/mediacenter/cellphone/router/whatever), sometimes two models are totally identical save for a firmware setting and you get something like this scope.If you ask any suit about this practice he or she will answer that selling the 100 MHz capable model at a higher price is what allows them to sell the 50 MHz model at a lower one, which is both technically true and a smoking pile of bullshit (companies caring for the customers? LOL!). It’s all about profit and nothing else.There are limits to this of course. A 500 MHz oscilloscope would use so expensive parts and designs that making a 50 MHz model out of it would be unprofitable, so expect to see this only in very similar models.",

What Input Device? Just Use Your Arm

"arm",
"input",
"tap"

This one could be a game changer. [Chris Harrison] and a team of researchers are showing off a method of
using your arm as an input device
. An arm band worn by the user picks up acoustic signatures created by tapping on your arm with the other hand, or taping your fingers and thumb together on the same hand. They’re achieving accuracies in the 82-97% range but it gets even better. Take a look at the video after the break and see what they’ve done by adding a pico-projector to the arm band in order to use your arm or hand as a touch display.
We liked seeing the
concept mice
from October, but the future of input devices might already be attached at the elbow.

[kernelcode] has built this pretty slick looking
sequencer/groovebox
and shared the process with the world. At its heart you’ll find an AVR atmega168 along with a hand full of buttons and blue LEDs. He says the total cost was somewhere around £15-20, so that’s somewhere under $40 for the American readers. There are tons of great pics of the build and it looks like he’ll be uploading source code soon as well.

Working with easy replication in mind, [Peter] is building
a 3D laser printer
. The majority of the machine is made from laser-cut acrylic held together by parts that are inexpensive and available at your local hardware store. In the end this will lay down a layer of powder, use a laser to fuse the powder together in the outline of your choice, then repeat. This is known as
selective laser sintering
which is sometimes used in commercial rapid prototyping and, like a lot of
other cool technologies
, came into existence as a result of a DARPA project.
Sorry folks, this is not a fully functioning prototype yet. [Peter] is searching for the right laser for the job and a source for the powder. If you’ve got a solution please lend a hand and let’s see this project through to completion.

"content": "I thought about doing a very similar thing, but I wouldn’t use a laser…I would use a cheap DLP projector from ebay. Color quality would not be an issue since I’d be using as a focused light/heat source. I might also hack it to use a more inexpensive bulb also. With the right optics one should be able to focus an XGA (or higher) resolution projected image down to a pin-prick of hot light (which could be highly controlled). This way one could move up from being able to print one pixel at a time (with varying degrees of accuracy) to a DPI rating comparable to a high quality ink-jet printer. The hard part then would be to find a way to stabilize the projector assembly, as vibration would become your enemy. Having the optics stationary would be best. The color of the powder one uses would also be an issue (the more opaque the better), since you wouldn’t want to over-fuse and loose the clarity of the print.Software would also be a breeze with a projector method, since it would simply act as a monitor showing a zoomed-in version of the layer currently being printed (in solid white), moving across as the print arm moves, etc.",

Inkjet print heads require much smaller steps, meaning we need either more expensive steppers or a smaller build area. powder deposition tends to be much weaker then filament deposition. making structures with powder would be very hard.That being said I know of a reprapper who is working on a reprapable printer that uses this method and commercial laser printer toner, which you can often dumpster.",

Liquids are easy to do, but for the solids we take a small amount of the sample and sprinkle it with either KBr or CsI powder. It is then compressed into a glass and an IR beam is shot through it.My take is that you could use a plastic or acrylic powder mixed with some CsI and while you wouldn’t want to pressurize it, a laser may be enough to excite the electrons and cause binding. The reason I suggest CsI is because it is absorbs but doesn’t reflect light from as far as 5000 cm-1 to 200 cm-1. It would not be affected by the laser, but the proper plastic would, causing it then to bind and form a solid glass/plastic layer.Like I said, I really have no evidence or basis for this. I haven’t done any research into the structures of powders and I’m probably wrong anyways. But I thought I would just share something. I’m not a polymer chemist also, so I don’t know much about synthesizing plastic polymers.",

A simple LED/phototransistor pair will then be sufficient to measure the location to within 0.2mm or so.Yet another hack is to obtain a spare touchscreen and have your laser module set up with a pen attachment touching the surface. this is not the most accurate method but has the advantage of being easily calibrated and repeatable.#include “$0.02.h”",

For the powder, I have been working on a way to locally change the index of the material used and fusing it should be easy (I have been using silica which is great a great compound thanks to an high the ablation threshold). Therefore, the physics behind this is mainly based on non linear optics that is why pulsed lasers are required (pulse duration less than the picosecond) in order to create a plasma without thermally affected zone. If you succeed into getting enough power for your laser, everything should be easy. If you need any links for publications, just ask me, I ll be glad to send you some on this field.",

All the off-axis rays get cut off, and the problem of focusing the light to a point source is simplified. A point source enlarger could easily focus light enough to resolve the silver grain of the film onto the printing paper, so sub millimeter resolution shouldn’t be a problem at all.

Parts are printed using the thermoplastic extrusion method using a mixture that is 60% metal and 40% binder. Afterward, the parts are heated up until the binder melts away and the metal particles sinter into a solid object. The finished product is about 98% solid by volume. There is about 20% shrinkage from the green part to the metal dense part.The problem with using a laser to melt metal powders is that most of the harder metals ball up. Most Selective Laser Sintering machines that print metal use a harder material particle that is coated with a softer material like bronze. The laser then melts the bronze surrounding one particle to the bronze surrounding a neighboring particle. Once again, the part is cooked in an oven at an extremely high temperature until the base metal starts to melt. The majority of the finished part is steel or a different base metal, but there is always some of the binding material left in the part.",

[Rob Stewart] put in a lot of time and built
this lighted display
at great expense. It displays four letter words using a word association algorithm to pick the next term to show. What interests us is the motorized display. It is made up of fluorescent tubes but they’re not fixed in place. Each can be rotated, as well as moved along a linear path to form any letter in the alphabet. Check out [Rob’s] build logs for the details on how he pulled it all together.

Your Hard Drive Needs A Diamond Blade
|

"chop saw",
"diamond blade",
"hard drive"
] |
If you find yourself in need of
a precision chop saw
don’t overlook the value of adding a diamond blade to a spinning HDD platter. [Tony’s] four-part writeup of this build springs out of some very special design considerations for a ham radio that operates in the 47 GHz band. That frequency pretty much rules out using normal components in the circuit and in his case it even makes connecting the components together difficult. He’s using this chop saw to cut small pieces of a ceramic substrate with gold traces on them that will be used to route the signals on the circuit.
We’ve seen hard drives used in
a couple
of
different clocks
, and even as
a set of speakers
. This one makes for a nice addition as a way to reuse those defunct devices that litter your junk box.
[Thanks Thomas]

"content": "Nice build Tony!Next time you want to make the inner platter perfectly round, one answer is to cut it to a slightly oversize diameter on your lathe (perhaps +.010 if you can manage the accuracy,) then mount it back on your hard drive spindle. Mount a rotary grinder (Dremel) on the chuck so the axis of the grinder is parallel to the axis of the hard disk drive motor, and the grinding wheel is centered on the platter. Rigidly fix the height of the chop-saw vertical travel so the platter can meet the middle of the grinding wheel. Using the hard drive motor to spin the platter at full speed, bring it down to the final diameter by moving the chuck very, very slowly into the rotating platter. Sparks should be no brighter than barely visible during this operation, or you could distort the platter with heat or cause some problem.I would consider using a dribble of water or a mister as a coolant during this operation, but if you’re going slow enough it shouldn’t be necessary. Keep in mind that as the aluminium platter gets hotter, it expands. A hot platter will give a falsely large diameter reading.The trick is to use the mounting position on the axle as the axle for truing the wheel. By definition, it won’t be out of round, as long as you finish the cut extremely carefully.You could also consider shrink fitting the blade to the trued platter. Leave the platter over the size of the blade’s inside diameter by .003 or so. Make sure the platter is just slightly too big to fit in the blade’s hole. Place the platter in the freezer for an hour, laying flat. Lay the frozen platter on a cool and very flat work surface. Lay the room-temperature saw blade on the platter — it should fit easily. As the platter heats, it will expand to fill the blade’s inner diameter, leaving a very snug fit.",

When the Department of Natural Resources of Australia decided that they needed to capture data about the natural flooding of a cave, they turned to a hacker to get results. The goal was to photograph the area during these floods with an automated system. In the end, they used a
gutted Lumix digital camera mounted in a trash can, covered in aluminium foil
. Though it sounds a bit silly, the final product turned out quite nice. You can see the build log, schematics, and results on the project page.

[David Findlay] has been hard at work on his Arduino iPod remote library and is now showing off some
Wii Nunchuck control
in the video after the break. When we looked in on his work in September he was
using a Staples Easy Button to control the iPod
. Now he’s added all of the functionality for
iPod simple remote mode
, and most of
the advanced mode
.
Advanced mode works well with his iPod Photo but the
iPhone just returns errors
. We know that
Apple uses some tricks
to keep unauthorized accessories out, so we hope that [David] finds a way to
sniff out the necessary accessory protocols
from an approved model.

Is it possible the iPhone expects the bytes in a different order or encrypted? Most likely it simply expects some kind of extra authentication signal at some point before or after sending commands that other models of apple products simply ignore. Good luck with the sniffing, I’m looking forward to seeing how much more progress can be achieved with this and how long full compatibility takes.",

Failing bluetooth, wifi/3G over TCP/IP works just fine too, though with slightly more latency.Using the ‘duino instead of – oh, I don’t know…say the PIC board designed to be used with the iPhone/iPod connector? – is just bad form and actually costs more. I hate Arduino as it brings something that should require skill and fundamental understanding to a market that has none. Do you think more than 10% of ‘duino users could actually design and produce their crap without one? I really doubt it.The WiiMote + Chuck + Droid take less room than this contraption and work just as well.

While looking for a way to injure his neck and live in the World of Warcraft all at once, [Gavan Woolery] came up with the idea for this
virtual reality setup
. That monitor, residing just inches from his eyes, is putting out 1080p at 120Hz. His plan is to pair up the motion sensing seen in the video after the break with an
NVIDIA 3D Vision Kit
for something close to total immersion.
To be fair, [Gavan] never mentions
WoW
, but we all know
where this is going right
?

We see stereo vision 2D and our brains build a 3D image out of it.Since nothing you ever *see* will actually be better than stereo vision 2D, what we have now is just as “3D” as what you see with your eyes everyday.What *you* seem to be complaining about is actually not the objects “not being 3d” but about lack of user interaction. (Ex: My head is in spot x, I want to see from the pov of spot x.)Personally I think this is kind of a dumb want, and useless outside of video games. (Movies have directors for a reason, they choose the angles, it’s an art. You wouldn’t want to see less than the person sitting next to you in a theatre because the angle wasn’t right, that’s dumb.)However, if you wanted *your* 3D really badly, it could be accomplished just fine with head tracking, like in the video in this post.Either way, I for one, love the 3D we have right now and think it’s awesome.",

Glad to see everybody is thinking about this though :)",

the folks over at OpenSchemes are at it again. This time they’ve
cracked open a low end ZerPlus logic analyzer and modified it
to function the same as the higher end model. The 16 channel version they purchased appeared to be fully capable of handling the 32 channels of the more expensive model. The installation of the additional components looks like it might be somewhat difficult, but it is certainly cheap.We love seeing things
upgraded for cheap
. You might recognize OpenSchemes from when they upgraded the
DMM tweezers
or hacked the
USB serial adapters
.

They offer a proper input stage and they are calibrated (which is important at such high speeds). Yes, they are $5000, and yes, that’s probably only a fraction of the costs – but still, buy a good Virtex FPGA, the fast&big SRAM, the proper interconnection/headers, and you’re at least in the $500-$1k range.I like DIY measurement electronics, and I use them a lot. But show me the DIY oscope that goes beyond 100Mhz *and* costs less than, say, a Picoscope with the same specs.I *do* agree on that analyzer software (modules) are totally overpriced. I can write a I2C decoder in less than 10 minutes in python, and it costs like $500 for my scope.",

It suits is purpose well for debugging simple low bandwidth circuits since people new to logic analyzers don’t have to worry about sample depth or finicky triggering, it just blasts everything to the client over usb limiting it to 24mhz.The LAP-C is ostensibly a real logic analyzer in that it records everything to a high speed sram and then offloads that to the PC. This can be a problem for beginners but it is the only way to get sample speeds in the 100+mhz range.This hack is amazing because it allows you to upgrade your 100 dollar 32kbit device to the 300 dollar 128kbit device by just twiddling a few values in software. If you take the time to solder all the passives in you can then turn your 100 dollar device into the 700 dollar model. Thats a DAMN good hack.@unknown thanks for the hex dumps",

CNC Egg Decorating

Lacking the patience to do it by hand, GeekPhysical built
a CNC machine to decorate Easter eggs
. We do mean eggs from chickens used to celebrate the Christian holiday of Easter, not
hidden nuggets in technology
used to amuse geeks. The results seen in their video (after the break) are quite impressive considering that the printing medium is not perfectly round nor perfectly smooth. The hardware design is ingenious; one servo rotates the egg, another is mounted on one side of the egg and moves a track in an arc so that a felt-tipped pen will follow the curve of the shell. The pen moves in an out along that track through the use of a third servo physically removed by a
Bowden cable
. We were able to get a closer look at the hardware via their
Flickr set
and the device is indeed Arduino powered. This fun build is a great way to celebrate the season!

A
Nixie tachomete
r is new to us. We’ve seen tons of various displays, but not a tachometer. After having extensive annoyances with the factory ignition timing system in his totally awesome
Holden Gemini
, [Brett] installed a MegaJolt electronic ignition system. To top things off and add that extra bit of flair, he built a nixie tachometer to sit on his dash. Not only does it have the numeric read out, you can see a nixie “bar graph” on top as well. Skip to about 2:30 if you want to go right to the action. You can download the Arduino code from the forum post.

What weighs 120 pounds, can fly at you near 20mph, score soccer balls, climb 90inch tall towers and more all while remotely controlled? If you said a robot from this years
FIRST
, For Inspiration and Recognition of Science and Technology, competition congrats
you’ve won one internet
.
This past Thursday, Friday, and Saturday (March 25-27 respectively) the Oklahoma FIRST regional competition took place. Once again I, HaD writer [Jakob] was lucky enough to not only attend, but compete! Check out our full breakdown after the jump.
Readers may remember some time back when we explained he
OKBEST competition
, and noticed it had striking similarities to the FIRST competition. While the build time is only 6 weeks for both competitions, that is where the similarities end. We would love to give a rehash and an explanation of differences, but readers might like to simply read and compare for themselves between BEST and FIRST and realize they are completely different games.
This years goal for FIRST, is in short, a soccer game. A field with 6 robots (1 robot per team), three blue, three red, battle it out head to head; blocking, scoring, and more to be the winner of the round. The addition of not knowing your two other teammates until the day of the match, and the inclusion of small ‘hill’s and ‘climbs’ increase the difficulty of the competition. Those looking for a full explanation of the rules and game type can find it
here
.
Team captain once again played the role to allow me to bring you this overview. Unlike previous robotic competitions, this was the first time our team, 3124, attended FIRST — making us rookies.
Our team’s design, if put into one word would be
simple
. The initial aluminum frame was constructed on kickoff day from our kit of parts. After that, to keep the soccer ball out from under the robot – we wrapped a (donated supply) wooden skirt around the perimeter of the bot. A pneumatic (donated, yet later not used, we broke too many rules with it) kicker was implemented. After having traction issues – a custom spring suspension system (perhaps the most complicated portion of our robot, two springs and a bolt) kept all 4 wheels securely on the ground.
While we were rookies, had very little funding, only two/three active members, and even more disadvantages we still managed to come out on top. By ranking 5th (out of 54 other teams) in the seeding rounds, we attended semi finals after asking teams 932 and 2842 to join us, and ended up 3rd overall; giving us the award for Highest Rookie Seed. Anyone wishing to watch some (or all) of the matches and learn how teams ranked up should check
BotsnLinux.net
.
First definitely is a unique experience, and I’m glad I was able to attend. Honestly, we didn’t expect to reach nearly as high as we did in rankings. But thus teaching, you don’t have to have tons of money, or a complicated system, or a large team, or the best design to win. The adventure of course taught us much more than that in the end as well. Hopefully values and ideas that can be taken and used in future endeavors for years and years to come.

"content": "@baobrienI don’t know if they’ve removed the autonomous portion of FIRST, but I know when I competed, we spent a large portion of our time figuring out the autonomous match time. It was usually the first 15 seconds or so when the robots had to perform completely autonomously. The years I competed (04-06), we had to deal with some dead reckoning (we used 8 bit rotary encoders attached to our drive wheels, and some non-driven encoders to account for slip), and image recognition and rangefinding using a CMUCam.Botball is a different beast. They’re tiny robots. A quick google search turned up lots of lego bots. I’m sure they have custom code, but still, they’re lego robots.FIRST is remote control primarily for safety. The robots are more complicated mechanically, and have orders of magnitude more power than Botball robots. If a FIRST robot was entirely autonomous, and a code error caused it to go out of control, serious injuries could result. Believe me, I was lacerated more than a few times by my team’s robots during testing in the shop.The nice thing about FIRST is that the robots are big. They require more than a code side of things. They require structure, stress analysis, and creating things that don’t exist already. My favorite part of FIRST was when I was CAD director, the team would say “we want to do this” and it was my job to figure out how to create the desired motion or action. It also teaches you not to screw up your design, and make sure it works *before* you build it. If a majority of your robot is made using a mill and lathe, chances are you won’t have the time or resources to redesign your mechanisms on the fly, so they better work right the first time. This is not the case with botball.",

However, that’s more for an equal playing field than anything, so that teams with absurd amounts of money don’t utterly demolish smaller teams. On the flip side, they give you the majority of the official parts. The only parts you *have* to use are their motors and their control board, really. The control boards obviously need to be the same, but that doesn’t eliminate any custom circuitry to interface with the official board. The motors really need to be the same, because it’s hard to source small amounts of motors some times, and a crazy overpowered drivetrain via non-stock motors could make or break a team at a competition. All the other parts are up to their teams. There’s also a material limit of $3000 (not including kit parts). I know from my teams, we used tons of 80/20, carbon fiber parts that we molded, non-kit sensors, and absurd amounts of custom machined parts. It’s 6 weeks of hell, but it’s a fun hell.-team 1272 and 1331, (both no longer exist, sadly)",

With this game, teams were joking about how you could actually use a human foot as your kicker, but that this would violate the rules as any one given human being will ((usually)) only have two feet, and therefore could not provide feet to more than two teams.The problems we saw this past weekend (and down in San Diego, as well) was that teams were paired in their alliances in a very random, but seemingly unfair, order. At the SD regional, we faced the #1 and #2 ranked teams on more than one occasion, and sometimes they would be paired together, against us.Also, field errors abounded this year, which actually cost us our Quarterfinal birth in SD, as we couldn’t connect to our bot in the last match.There are plenty of problems with every competition of all natures, but I really do like FIRST.

It downloads to the robot in a tiny fraction of the time a LabVIEW app would deploy, and its IDE (NetBeans; wish it was Eclipse) is fairly swift in comparison. Plus, there’s no stupid licensing issues. The first week events are always bumpy control-wise; the event organizers have gotten significantly more competent at keeping the event moving, though.Overall, FRC is pretty intense, and I would suggest it.-6th year FIRST member; 1 year on 1140, 3 years on 68, 2 years on 2586 as a mentor.

The game is not just about building and programming a completely autonomous robot, but also documenting the process and preparing students for a professional environment.First is more of a building challenge. To see who can come up with the best device and then drive it the best.I would argue that Botball is easier for rookie teams since, there is a little less of a learning curve documentation wise, and the game is designed so that a team with a simple plan carried out reliably can beat a team with a complex strategy that only works part of the time.The beauty of Botball is that it forces the students to become more proactive in the process since everything is done by the teams, and mentors are only there as high level coaches.This year at the Oklahoma regional Botball tournament, I saw sixth graders compete at the same level as high school seniors and the overall winner was a 6,7,8th grade team.I only typed this rant because I am disappointed when people group all of the engineering challenges together under robotics. I will reiterate an earlier post I made that if there is someone using a remote control to run a device, it should not be called a robot. I understand that there is an optional autonomous period, but if you robot can not fully function with out a driver it is just a RC toy.",

Long before Kick-off, our team is busy organizing, working out who will function best in each area. There is the huge component of marketing and fund raising – BIG fund raising – that many other competitions might require but do not recognize as part of the process. Marketing and fund raising are a huge part of innovative engineering and the experience is invaluable. There’s even recognition for web design skill – on trend, current and an example of the broad view FIRST takes on the whole process.Our kids gain experience in all of these areas. I think most importantly, they gain a respect for the talent others might have in areas where they themselves might not excel. How great of a life lesson is that? How many of us wish for that in our own work place as adults?I am also appreciative of FRC’s continued work to keep the ‘sports’ component to a minimum while still recognizing its appeal. Teaching sportsmanship in ALL areas, including those outside of ‘sports’ is phenomenal. “Coopertition” – I love it!",

The magnetic tape found in audio cassettes can be fun to play with. This installation, called
Signal to Noise
, relocates the heads from cassette players to the tips of your fingers in the form of a glove. An accompanying wall has vertical strips of tape which you run your fingertips along in order to play back the stored audio. Get the speed right and you can make out what’s on the tapes. Move back and forth and you’ll be scratching like the worst of DJs.
If this were teamed up with
a Melloman
it would make for quite a performance. See and hear this curious device after the break.

Add USB Playback To Some European LG Televisions

Here’s a pretty simple
hack to enable playback from a USB drive on LG televisions
. It only works on European hardware, the LH, LF, and some LU models. The hack consists of downgrading the firmware to version 3.15, then navigating through some service menus.
It’s not quite as hardcore as the
Samsung firmware hacking
, but the added functionality is really great.

The lower spec models don’t, but are effectively the same hardware, albeit with a slightly smaller screen. The USB port on my LG (which had this hack applied to it in January) is labelled for diag. purposes only, but frankly it just seems like it was easier for them to churn out the same basic hardware with only software differences :)As for living with this hack, it seemed like a good idea at the time, but we’ve barely used it. That’s probably more to do with the fact that we have various “magic boxes” scattered around the house to stream to the Xbox or AppleTV :-/",

DTMF And SelCall Signal Generator

"dtmf",

[Rogal] wrote a cell phone application called
ToneTool that generates audio tone sequences
. It can be used to output
DTMF
and
SelCall
sequences which are used by telephone systems and radio-telecommunication hardware. The software is written in J2ME so if you have a cell phone that can run Java apps it will probably work for you. This is like a digital-age
Blue-box
in everyone’s pocket. But we don’t think there’s too much opportunity for the mayhem seen with the original phone phreaking.
See him generating and sending DTMF commands over an
Echolink
network in the video after the break.

Driven by the relentless nagging encouragement of the Hackaday commenters, [Johndavid400] has
improved the Lawnbot 400
. No longer does it just sport a
makeshift wooden shelf
. he now has a wheel barrow attachment. It looks quite sturdy as long as that front hinge holds out. There is an actuator coming in the near future for dumping the contents as well. Also, we suspect that might be a
shovel
in this picture.

Robots From Dolls
|
Caleb Kraft

[
"Robots Hacks"
] |

"anime",
"creepy",
"manga"
] |
Here at Hackaday, we may be somewhat divided in our opinions of Anime and Manga. We were all
pretty impressed by this robot build
(
translated
) though. We’re not totally clear on who actually did this build, but we can see a few pictures and a video on the site. The original doll looks to be roughly 3 or 4 inches tall, judging by the Eeepc keyboard that it is standing on. We counted 7 servos stuffed into this thing with a controller board hiding in the back of its hair. You’ll have to watch the video to see most of the details. It looks like there is one in the head, one in each shoulder, both hip joints, and both feet. Though the motion at the end of the video is limited, we still think it is impressive. Creepy, but impressive.
note: the video is not embedded in the translated version. Just go to the non translated to watch it.
[thanks Francesco]

We may be good at soldering but when it comes to hauling topsoil our scrawny arms quiver. [Johndavid400] did the smart thing here by
letting the machine do all the work
. Instead of hauling an entire truckload of dirt across the yard one wheelbarrow at a time, he built a shelf on the top of
his Lawnbot400
. We saw this lawnmower Arduino-powered, remote control mower back in November. The addition of its ability to handle some of the manual labor makes it the perfect backyard hack.

Heated MakerBot Build Stage
|
Mike Szczys
|
[
"cnc hacks"
] |
[
"build stage",
"heater",
"makerbot"
] |
This
heated build stage
seeks to make 3D printing with the MakerBot a little easier. When hot ABS or PLA meet the cold, cruel world they have a tendency to warp. This was concern for [
Devlin Thyne
] when he was
developing our Hackaday badges
. What you see above is 10 Ohm nichrome embedded in clear silicone, then sandwiched in between two plates of glass. The device is made to interface with the MakerBot and includes a thermister for temperature sensing. With a small firmware upgrade you can now set the build stage temperature which should make larger printed objects a bit easier to deal with. A while back we saw
a hotbed for the RepRap
, but this implementation should be cheaper and easier for the smaller MakerBot applications.

Polaroid Instant Film, Reborn.

"film",
"polaroid"

The
impossible has happened
. While that may sound a bit over dramatic, the project itself was titled “the impossible project”. What is it that is so impossible? The revival of Polaroid instant film. This is not a newer, digital alternative, this is film you can actually buy and plop into your old Polaroid camera. What’s the big deal? All they had to do was start producing it again right? Not really. They’ve completely re-engineered it from scratch. That’s pretty impressive. We had heard,
early last year
, that they were going to attempt it, and we’re pleased to see that they’ve succeeded.
That being said, a handheld, home hacked digital instant picture device sounds kind of cool. It would probably be an easy one to build too.

Yeah, a Dye Sub like PoGo can be damn close in many ways for semi-emulating self developing films. But the emotional magic which began with peel and coat reached it’s pinnacle with SX-70’s Visible Progress of “While you watch” image forming. The other technical reality of SX-70 film centers on a presumption that pictures on that film are WAY harder to alter from what the lens saw.The whole team that has been responsible for restoring this tech deserves our deepest respect.",

[Chris Neal] is starting his hacking career young. He built this
fan-powered skateboard
for his fourth grade ‘Invention Convention’. The ideas were his own but he had some help with the construction from his uncle who owns a repair garage. On the back of the board there’s a motorcycle battery that powers the fan. We’re not sure where that fan came from, but apparently it can push a rider at about 3-5 MPH. [Chris] scored a free MacBook pro from this hack after being featured on the Ellen DeGeneres Show.
For some reason this sparks the memory of the
drill powered minibike
.

"content": "@osgeld@AndrewNo offense, but your comments strike me as being a bit lame.Any time you see a little kid swinging a wrench or pounding a nail into a board (instead of vegetating in front of some stupid video game) he/she should be encouraged and lauded.It’s easy to assume that kids have always been lazy button pushers, or if they actually ventured outside, taggers of road signs and brick walls. Not so. 50-100 years ago, kids spent their free time “hacking” all sorts of interesting things, including bikes, primitive go-cart-like automobiles, and full-sized hang gliders. They crafted home-built motors, crystal radios, water wheels, simple lathes, and their own mechanized toys.If you doubt this, you probably have never seen a copy of the book “The Boy Mechanic,” circa 1925. This was a thick volume of projects for boys. Granted, most adults these days wouldn’t have the knowledge or the basic common sense required to build these things, but our society has been dumbed down. It was assumed, at that time, that the average boy did have the requisite skills.http://www.amazon.com/Boy-Mechanic-Classic-Things-Mechanics/dp/1588165094Still not convinced? Find some copies of anything written by Alfred P. Morgan. Projects in his books included radios, amplifiers, turntables, geiger counters, “electric eyes”, motors, and more, not to mention homebuilt aquariums and chemistry equipment.Now, has this kid built an over-unity fusion reactor? No. But cut him some slack. It does my heart good to see a little kid “hacking” in the spirit of “The Boy Mechanic.” I’m also happy for him that he has family members willing to encourage and “help” him turn his ideas into something tangible.Good job, Chris.

…and wins. Well, 3rd in class, but still surprisingly well for such a
cheap entry
. This is truly a show that with enough elbow grease and
headlight fluid
anything can be accomplished
money just makes it a ton easier
.
Everything from the roll cage to the 5 minute gas tank fix was fabricated by [Bill Caswell]. Well — fabricated is a rough term for duct tape at that point, but this is still an awe-inspiring and truly motivational story for any hacker and car enthusiast alike.

Swapping Coins Cells For Capacitors For Noise Filtering
|
Mike Szczys
|
[
"classic hacks"
] |
[
"capacitor",
"coin cell",
"LR44"
] |
Here’s an interesting idea:
replace a disposable coin cell battery with a capacitor
in order to filter the noise from an external power supply. [David Cook] is taking advantage of the falling costs of digital calipers. He’s mounted one on his milling machine but noticed that with an external power supply the readings would sometimes reset in the middle of his work. The LR44 cell he’s replacing makes for very difficult in-place soldering so instead of permanently replacing it he built an insert that matched the form factor. The outer ring is from a piece of copper tubing and soldered to a PCB that he etched.
If [David’s] name sounds familiar it’s because we featured his
Happy Meal toy scavenging
a while back.
[Thanks Thomas]

Beginner Concepts: LPT Instead Of UC
|
Mike Szczys
|
[
"computer hacks"
] |
[
"beginner concepts",
"darlington",
"LPT",
"printer port"
] |
We see it all the time, a post based on an Arduino board with multiple comments calling it overkill. How exactly should you control your homemade peripherals if you’re not using a microcontroller (uC)? [JKAbrams] and [Tim Gremalm] answered that question with this
printer port (LPT) adapter
. They wanted an indicator light when someone in an IRC room was talking to them. By connecting a blue rotating light through a relay to the output of this fob they’ve done just that, but there’s room for much more.
The adapter uses a
Darlington transistor
array IC to protect the computer. A resistor between the LPT and the base pin on the chip ensures that current flow will be well within the safe levels for the computer. The Darlington transistor amplifies the output using an external power supply in order to drive heavier loads.
If you want a deeper understanding of the printer port
check out this tutorial
. LPT ports are becoming less common and that’s why so many projects are migrating over to USB (plus there’s no need for external power with most USB connected projects) but if you’ve got one, it’s probably not being used for anything else.

Turing Machine A Masterpiece Of Craftsmanship

"Turing machine"

Everything about
this Turing machine is absolutely brilliant
. A
Turing machine
uses a strip of material to record, calculate, and change data. [Mike Davey] built this one using servo motors, a Parallax Propeller, felt-tipped pen, and 1000 feet of film leader. The machine writes characters to the leader, reads them using a grayscale camera, and erases them with a rotating felt cylinder.
Watch the video after the break, it covers every one of the intricate details that add up to [Mike’s] perfect build. We loved
his Nickel-O-Matic
but he really outdid himself with this one. With our mouths still agape we’re going back for our fifth viewing.

The important point about TMs is that you can set up the FSM in such a way that it can read a description of any TM from the tape and implement that other FSM’s transitions, reading, writing, and tape moving. (i.e. you give Turing Machine A a tape where the first 1000 cells are marked with a description of Turing Machine B, and let it run, you will end up with a tape where cells 1001…infinity are the same as you would have gotten in cells 1..infinity if you had implemented TM B directly. If you are a purist you can make it slide the contents of the tape down to overwrite the TMB description to get exactly the same tape as TMB would have produced.)The fact that a TM can be set up to take as input a tape with a description of ANY possible TM, and then act as if it were that TM, makes it a Universal Turing Machine (UTM). Designing the transition table for the FSM to implement a UTM on this machine is an exercise for the reader, but it is not ridiculously hard. (It’s the equivalent of writing a language interpreter instead of a compiler.)Once you have a UTM you can hoopsnake it by giving it a tape with its own description on it. The interpreted UTM can then emulate a third TM, which can also be a description of itself and so on. It’s not very computationally efficient, but it works if you are patient.",

I have had interested from The Computer History Museum and Bletchley Park. Because I build for the joy of building and not that of ownership, I have always planned that I wouldn’t keep it forever.

8-bit Game Console With Wireless Motion Controller
|
Mike Szczys
|
[
"classic hacks"
] |
[
"8 bit",
"atari",
"console"
] |
[Luis Cruz] built a
gaming console with motion control
. The circuit above connects via composite video to a television and communicates with a wireless controller. The controller is on a smaller breadboard which includes an accelerometer for the input and the infrared circuitry necessary for wireless data transmission back to the home system. Take a look at the first game he developed for it in the video after the break. There’s some details available (ie: he’s using ATmega168 and ATmega328 chips) but we’ve asked him to post code and schematics which he is currently cleaning up for mass consumption.
Ah, the 8-bit sound in that game takes us back to the glory days of
Atari
and Intellivision.

Here’s
a collection of little LEGO oddities
. Some of them exhibit a purpose, such as this interesting take on
a line-following robot
. Others, like the four seen above, are just automatons built to bring a smile to your face through their motion. There are dozens to choose from, with several pictures and a video of each. See the clips of these four after the break. Oh, and don’t worry, we didn’t find any
LEGO
iPhone docks
, just
cleaver mobile creations

That’s A Big Flashlight

"flashlight"
] |
Going camping? You’ll need an extra backpack to carry
this flashlight
along the way. On the business end you’ll find 500 five millimeter super-bright white LEDs, on the opposite end there’s ten times the number of controls you’d expect on a flashlight. At full power, the LED array pulls down 50 Watts, making us question the battery life of the unit. Check out the walk-through after the break. The LEDs are mounted on proto-board, making for some extreme point-to-point soldering. During the control demonstration there’s a background noise like a jet powering up, what’s that all about?
While this terrific torch brings a grin to our faces, we wonder if it wouldn’t do better as
a vehicle mounted illuminator
. Or if a microcontroller was tossed into the mix some creative code could make this a pretty powerful yet
non-lethal weapon
.

Perfect for slow walking, rather efficient due to a crude built-in inverter, and the design is simple. Why shouldn’t it scale up? Perhaps for a bicycle some 50 diodes would be enough. But still there are some issues:1) Decent diodes that push >10cd @15° are ludicrously expensive where I live, too :(2) The reflector. The Chinese are using no fancy paraboloids, just some kind of plastic trough with vacuum-deposited aluminum coating. Which is still better than nothing. However… Aluminized PET films: not difficult to obtain, easy to handle, but too transparent. A chunk of polished aluminum tin: from ubiquitous soda cans, may involve some electrical insulation, but still needs a lot of polishing (and local shops here even don’t know about polishing compounds). What else?3) Some small resistors are still needed if you want to be gentle on those LEDs — that is, to counteract voltage drop differences when connected in parallel.

Heated Aluminum Bed For MakerBot
|

"3d printer",
"aluminum",
"heated",
"makerbot"
] |
[Keith] built this
aluminum-plate heated build stage for his MakerBot 3D printer
. We just saw a different MakerBot heated build stage yesterday that
relied on glass as the printing surface
. Keith’s design is similar to the
aluminum RepRap bed
but scaled down for the MakerBot. He had a piece of aluminum machined the to correct dimensions, and perfectly flat to use as the printing surface. The yellow surface is caused by
Kapton
tape applied to the top of the plate. This heat-resistant covering is perfect to print on, resulting in glossy smooth surfaces that are easy to remove once the printed part has cooled. He’s working on improving his mounting technique to achieve prefect level so that he can print without a raft.
[Keith’s] writeup is phenomenal. He’s sharing knowledge in a way that is useful even if you’re not building the exact same kind of project. Follow his lead with your own write-ups, then
let us know
once you’ve posted them.
[Thanks Marty]

I wonder if there’s a fluid like (oil or something) that won’t interfere with the extrusion process.If so, you could do the extrusion while submerged in that liquid while it was heated to the same temperature as the plate until the extrusion process is over.",

Update: Samsung TV Firmware Hacking

"firmware",
"samsung",
"SamyGO",

] |
[Erdem] sent us an update on his work with
the SamyGO project
. You may remember this Samsung TV firmware hacking initiative from
our post back in October
. Since then many more TV models have been added to the compatible list. They have also worked out a way to
defeat the AES encryption and RSA signature checking on the CI+ devices
. Want to lend a hand? Take a look at the compatibility table on
the main page
and see if you have one of the TV models they need testers for. Otherwise, read
the wiki
, hit the
downloads page
, and unlock the hidden abilities of your
boob tube

[Fedeortiz12] and his team are
nearing completion of their CNC mill
(
english translation
). They set out to build a standalone machine that takes
G-code
in the RS274/NGC format from an SD card and machines parts accordingly. At the heart of the system is an ARM LPC2148 controller with a character LCD and control pad for operation. The guys have made a teaser video showing the project being tested with a felt-tipped pen. Take a look after the break.
We’d like to see the final product milling PCBs. We’ve always been a little jealous of the
PCB milling setup
that [imsolidstate] has in his shop.

[Theo Jansen] is building
lifeforms that will live and thrive on the beach
. He calls them StrandBeest and uses PVC electrical conduit, plastic tubing, and lemonade bottles as building material. The many-legged creations are amazingly advanced, able to count steps, sense and flee from the water’s edge, and protect themselves from high wind. He gave a TED talk back in 2007 that we’ve embedded after the break; it’s uncanny. See examples of his creations using fans and sails to store wind energy as compressed air in the lemonade bottles, then use that pressure for locomotion. He also demonstrates a binary step counter and water sensor.

The Strandbeests operate autonomously without any centralised controller or nervous system: each component reacts independently in a simple, and the interaction of the reactions creates emergent behaviour (hydrophobia, etc).

While not meeting all the requirements for life (e.g. self-replication,which Viruses also fail on, growth, adaptation), they do exhibit Homeostasis, Organisation, Metabolism, and response to stimuli.

As an engineer, hearing him talk about them as if they are alive is a little disturbing and, as someone else said, sounds conceited. However, his speech was not just to engineers, but artists and math majors, and everyone else. The more he talked about the emergent behaviors, and the things he was trying to build into them; a fear of water, ability to sense the surface they walked on; the more they did seem to get closer to being alive.If we want to complain about it being ‘alive’, we should complain about programmers talking about genetic or evolutionary algorithms. Or computer ‘vision’ and ‘sensing’. Just because the machines do not yet meet all the criteria of life does not mean they will not at some point. After all, mixing this with some of the rep-rap reproducibility could result in a machine that would be a very basic form of life.As a engineer-in-training, the pneumatic oscillator built from not gates was very interesting. Studying how he uses that to act as the clock cycle for the rest of the beast’s mechanics was worth the wait of his talk.",

Perhaps an amateur one depending.Likewise I also don’t consider anyone who thinks about something really hard or intelligently to be a philosopher, perhaps an amateur one depending on the method.In the end philosophy, in itself,is still absolutely important. However due to the nature of it you don’t often see tangible results. Usually because the philosopher passes on the thing to someone else to actualize it.Such as the mathematicians and philosophers who conceived of formal logic, multiple realizability and computational theory which then got passed along to the engineers who turned those theories into practical applications.However most people just assume philosophy to be random ramblings about reality not being real and stuff like that.",

Some of you may remember when we introduced you to [Kyle’s]
Electronically Modified Didgeridoo
. Those same members will have their hearts warmed knowing he’s still playing and advancing on his Didgeridoo, now including
real time video processing
. There isn’t too many details aside from it being controlled by an ATMega168 and an unknown analog switching chip, and in its infancy it just looks like a bunch of dancing white lines but we expect this to turn into one amazing display.
Oh, and those determined on making their own Electronically Modified Didgeridoo should keep an eye out for the
April ’10 issue of Popular Science
where the instrument will be featured.

Floppy Disk Augmented Reality Is A Head-scratcher

[Iain Gildea] tipped us off about a drill-powered coffee grinder he made but it was the
floppy-disc augmented reality display
a few paragraphs down that caught our attention. He’s taken 36 white floppy discs, sprayed one side black, then mounted them each with a center pivot into a 6×6 grid. Through a convoluted system of pulleys and servo motors the display can be manipulated to produce
augmented reality markers
. After the break you can see the display itself, then the result of viewing it through a webcam.
We’re amused, but also scratching our heads. There must be an easier way, such as
a light-up grid
covered in dark plexi or something along those lines. But then again, it’s his hack and he can do what he wants… and
he seems to have a thing for floppies
.

Die Bloodsuckers – Pew Pew

"mosquito",

] |
In a bid to combat malaria, Intellectual Ventures is
developing a method of killing mosquitoes with lasers
. The system is called a Photonic Fence and identifies the beasties by the frequency of their wing flapping (hey, that’s exactly how we know when they’re dive-bombing our heads). Once locked-on, it’s death to the filthy blood-suckers.
This story was latched onto by the gambit of news sources in the middle of 2009. Since then, the development team has added some pretty interesting info on their webpage. Last Feburary several videos of mosquito flight were posted. These were shot at 6000 fps using specially designed photographic rigs (probably
much like this one
) to make sure the shots were in focus. Now they’re
slated to give a talk at the 2010 TED conference
. The publication of these talks sometimes lags behind by several months so be patient. Watch the video after the break to get some abstract shots of the hardware being used; they’re not giving up the goods until the conference.

XBMC Hiding In An SNES Controller

"controller",

"usb",
"xbmc"

Here’s another
SNES controller converted to house a USB system
. The
one we saw last time
used a kit as an adapter for the controller but this version uses a home-built PCB and an ATmega8 microcontroller with
the latest revision of an open source adapter
for NES and SNES controllers. As you can see after the break, [Atarity] built the adapter, then added it along with a USB hub and thumb drive so that he could run a copy of XBMC from the controller. Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.
You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

Microchip’s PIC Development For IPhone And IPod
|

It seems a bit late to the party, but Microchip has just announced
a family of PIC development boards for Apple products
. The
three offerings
include a digital audio development kit, 8-bit accessory development and charging kit, and a 16-bit accessory development and charging kit for iPhone or iPod.
We’ve seen a lot of
homebrew Apple addons that use microcontrollers
. This not only takes the hardware interface to the next level, it does it
with Apple’s blessing
. But somehow that doesn’t seem like quite as much fun.
[Thanks Juan]

Being hackers, sometimes we just want to hack something together, not engineer it. This
projector is a great example
. Made mostly out of cardboard and duct tape (
or duck tape if you prefer
). He picked up a 12v LED array, a cheap fresnel lens, an LCD from a “back up monitor” and a focusing lens taken from a magnifying glass. Sure,
we’ve seen better
, much better. But seeing an evenings worth of feverish wire twisting and taping is always pleasant. It may look pretty dim in the video, it may be as well, but keep in mind that it is common for them to appear much brighter in person or if shot with a night setting on a digital camera.

Flash Animations On Peggy2.0

[vimeo=http://vimeo.com/10453715]
The LED display toy known as the Peggy2.0 just keeps getting cooler and cooler. [Leonard] is now sharing with us how we can
stream flash animations to one
. It requires some Java and an Arduino, but the final effect is quite fluid and responsive. We’ve seen the Peggy grow from basically an electronic litebright to
doing video
and even being
chained together
to make larger displays.

Leapfrog DIDJ

"Didj",
"Leapfrog",
"linux",
"woot"
] |
Since we first mentioned the Leapfrog DIDJ, a lot has happened. A number of avid readers of Hack a Day teamed up with a couple hackers experienced with the DIDJ, and have managed to make some huge progress into making a linux based game console on the cheap. For all the readers who missed out on the last sale on Woot, its about time for a
second chance
.
The team working over at the
HackerFoundry
forum have managed to gain serial console access, map the file system, create a fake update server, and are almost at a point where replacing the stock OS and firmware can be done with software alone. They have also designed and tested a homebrew cartridge with a slot for a microSD card and breakouts for expansion and debugging.
Right now they are looking for someone with experience snooping USB protocols to figure out how the device communicates to the computer, as well as anyone who is interesting in just testing or playing around with what they have done so far. There are a number of tutorials and walk-throughs on the
eLinux wiki
. Its amazing how far this group has come in just
two months
.

Now I can connect my FTDI to the Didj in a non-permanant way, since I use it for other purposes as well. I also can connect my SD breakout from sparkfun with just a few jumpers. I got serial working, but I haven’t done anything else as I’ve been trying to finish my other project first.

Guitar Echo Pedal Built With Mbed
|

"echo",
"guitar",
"mbed",
"pedal"
] |
[Vsergeev] built
an echo pedal for a guitar
or with other audio manipulation applications. He used an mbed microcontroller for the project. You may remember Hackaday writer [Phil]
labeling the mbed an ‘Arduino on steroids’
, and it certainly handles this audio processing quite well. We’ve included a clip of the echo effect after the break. During the design process, [Vsergeev] used
LTspice
to simulate the analog circuitry and make things right before committing to the physical circuits.

Basic soldering skills required, and you’ll need a small breadboard to prototype circuits on.By ‘basic’ programming did you mean simple programming, or BASIC programming as in the old Beginners All-purpose Symbolic Instruction Code?

Cardboard record player
[Yen] tipped us off about this
cardboard record player
. It’s a marketing tool that you receive in the mail. Inside the cardboard packaging is a record and the packaging itself can be folded into a player.
Hackable handheld
The
NanoNote is a tiny handheld
housing a lot of power for a small price. It ships running
openWRT
and sports a full keyboard, 336MHz processor, 32 MB ram, and 2 GB of flash memory. Not bad for $99. [Thanks Drone via
Linux Devices
]
Virtual page flipping physical interface
Love reading ebooks but miss flipping through the pages? [Marcin Szewczyk]
developed this interface
that lets you flip a couple of sheets of plastic to turn and fan through pages on the screen.
Augmented reality tat
Not interested in supporting an ink artist or just can’t decide on the design? Perhaps you should
get an augmented reality marker tattooed on your arm
and have the art digitally added for those who have already made the switch away from using their analog-only eyes. [Thanks DETN8R via
Asylum
]
Cooking with a CPU
[Bo3bo3] is
practicing the art of cooking with processors
but he’s bumped things up a notch. Instead of
cooking inside a computer case
, he removed the processor from the board and made it USB powered. [Thanks Waseem]

Automated Rain Barrel Watering System

[Dmritard96] built this
automated watering system
to keep his garden growing while he’s out-of-town. It uses rain barrels, which capture and store rainwater, as a source. These barrels provide very low water pressure so he’s added a battery-powered pump along with a solar array for recharging. Don’t worry, if the rain barrels run dry there’s a float sensor that will switch the system over to city water and stave off those wilted leaves.

From here it feeds the washing machine (clothes) and the toilet. Considering our water is metered, it saves about £100 UK per year. IT uses a little intelligence to only pump when the top tank isn’t full, and if there has been no rain in the main tanks on the last pumping request it adds 5 hours onto the time before the next test. I’d have liked to have volume monitoring for the pump/demand system but I felt a more failsafe approach was to use float switches.

"content": "Instead of designing for water delivery using pressure, as in this system, a simpler approach for small plots may be to design for a free-flow system that waters a bit more slowly with no pump and nil pressure. Low pressure irrigation won’t be as efficient with water usage as the pressurized drip systems used in arid reigons, but low pressure/free flow will surely be simpler/cheaper to build and maintain. In place of presurized smaller pipes, unpressurized larger diameter pipes are used to get water to where it is needed. The larger diameter piping is actually cheaper since it can be very thin walled. This type of system is pumpless so it needs only a very tiny solar panel and battery to run a timer and solenoid valve.I guess it should be mentioned that there is a requirement to make sure there is even flow throughout a low-pressure distribution system. Relatively large diameter feedline is run from the rain barrel and small diameter supply tubing is plugged into it (hot glued?). So long as the open ends of the supply tubes are staked at equal elevations, each supply tube end will provide the same volume of water as it’s neighbor. Equal elevations = equal flow. Need more water in one spot? Just lower the open end of a supply tube. Need still more? Plug in another tube or switch to a somewhat larger diameter tube. The overall watering that takes place is faster than drip systems but slower than sprinklers & sprayers.If water has to flow uphill or over a distance, irrigation water should be distributed from an elevated rain barrel and/or fed into a low-pressure pump. If a pump is needed, a high-pressure (70 PSI) diaphram pump as mentioned in the documentation takes a lot of power to run and would be a serious mis-match for free flow irrigation. A small centrifugal pump is energy-efficient and will do the job very nicely, plus centrifugal pumps cost less, last longer, and require nil maintenance when compared to diaphram pumps. Another benefit is that the watering controller designed by Dmritard96 can now switch to a smaller/cheaper battery & solar panel system to feed the much smaller pump.",

The total amount of rainwater collected even if all homeowners used a rooftop collection system is an impossibly small fraction of the rainfall over the rest of our State. This, of course, has nothing to do with California or any other state, but CO’s voting citizens are responsible since they voted for the people who wrote this weird state law. Maybe, finally, more folks in CO will register and do some actual voting — this time to replace the people who created this ugly law. We need to use natural resources as they come to us from nature. It makes no sense to have a law which actually mandates that CO residents can only use rainwater if they purchase it out of a pipe after huge amounts of energy are spent in collecting it and pumping it back to where it came from.

This collected rain water may not be “potable” in terms of direct human consumption, but if may be just that, no information given on the collection system, and if irrigation only was the planned use, no need to go through the extra steps to in sure the collected water is potable.@skipper; tantris As I read the project, the pump is needed because the system uses the city water for a back up, so the actual irrigation plumbing has to be fitted to the city supply, and the rain water collection has to be matched to the irrigation plumbing. However a gravity system with a city supply backup could be as simple as having the city supply fill the barrels when the water level in them drops. Also there’s a practical limit as to high the the rain barrels can be, so a pressurized system is pretty universal in it’s applicationAs far as I know small water catchment systems are legal in KS. Apparently in KS cities are allowed to modify streams flow to fit their needs, but farmer FAR upstream can’t. KS has sued both CO and NE over the amount of water both states hold back from KS. Rain belongs to those down stream as much as it does up stream. Whenever this topic comes up, I’m surprise of the number of people ignorant of the events that lead to law that many find difficult to understand. yea the law needs to be changed, but, no one really want’s to open the water rights can of worms, so the best thing to to is to ignore small residential water catchment consumed on site. The two things that may really effect our water supply is the push for the privatization of water systems, and climate change. Climate change is real and has been ongoing. The old timers have noted it, but simply say the weather has changed. PLEASE note I didn’t mention why the climate is changing. :)",

While a more passive system would certainly be cheaper, a safe structure to hold a drum (actually 8 drums) that size full of water would not be cheap.

If not do you know what the proper way to do it is?",

The solenoid valve is not sufficient it will leak at some point. So if the city water pressure drops, you would be pumping grey water back into the city system.",

(that’s also how washing machines are set up.) with your setup i would have the city water go to the rain barrel. whenever the rain barrel runs dry, a few inch of city water are added. the hose with the city water coming in should be further up than the rain barrel overflow, so nothing can get siphoned back out (air-gap system). you would need the pump all the time, but with solar that should be fine.",

With summer just around the corner you should try out a build like this
constant pressure water gun
that [JLspacemarine] put together. Similar to the commercially available
Super Soaker toys
, this isn’t just
a squirt gun
but includes a water reservoir as well as a pressurized air chamber. Pumping up the air chamber allows for a constant stream when the trigger is depressed. [JLspacemarine] used a combination of hardware store items such as PVC, ABS, springs, hose clamps, and valves to bring this all together.
[Thanks Danukeru]

While surfing one of our

, we came upon
this little jewel
. We can’t really tell if this is hack-worthy, or just a deathtrap, so to help decide…
Mechanics crawler + 80cc motor – safety concerns = deathtrap
It’s really that final “
Brakes?
Why would I need to stop?” that puts this project over the edge. Regardless, check out a video after the break. And please, do not try this at home.

This method of book digitization allows you to
scan an entire book by fanning through the pages
. It uses a high-speed camera that captures 500 frames per second to get a good look at each page. Processing software isolates each pages, analyzes any curve in the paper due to the flipping, and smooths out the image for better optical character recognition results. The greatly reduces the time it takes to
digitize a book
, even compared to
setups that automatically flip pages
.

Graffiti Machine Sprays For You
|

"graffiti",
"spray paint"

[Ben’s] father was a metalworker and the combination of being around metal fabrication for most of his life and getting a couple of art degrees brought together a satisfying combination of hacking skills. Above you can see a
Graffiti Machine
that he built, which we’ll look at in-depth after the break.. This isn’t the first CNC machine he’s worked on. [Ben] became interested in rapid prototyping but was put off by the cost of commercial cutters, which led him to build his own
CNC plasma cutter
.
[youtube=http://www.youtube.com/watch?v=5uFsZEqCBV4]
[Ben’s] creation consists of a vertical gantry that houses the motors as well as a carriage for the spray paint ‘rattle can’. He’s using stepper motors and belts to move the carriage and gantry with a controller that he picked up from
HobbyCNC
. Let’s look at how he put it all together.
This is the can carriage. On the right, above the can, you can see the motor used to start and stop the flow of paint. To the left you can see the timing belt used to move the carriage up and down. Its ends are secured with C-clamps.
[Ben] uses the head of a machine screw to depress the valve of the rattle can.
The top of the gantry houses motors to move the gantry itself as well as the can carriage.
The full gantry is one piece with the can carriage traveling along its length. You can see the timing belt that the gears use to move the can.
The two images above show the belts used to move the gantry along the top and bottom horizontal tracks. A rod travels the length of the gantry, driven by a stepper motor on one end to move the gears of both the top and bottom belts.
This image shows the angle-bracket that is used as a track. This gives the machine horizontal scalability.
This closeup shows a skateboard wheel with a slot cut in it. This keeps the gantry firmly seated in the track as it moves.
[Ben] ties the system together with a Linux box running the
Enhanced Machine Controller
. He’s hoping to pit man against machine some day in a graffiti showdown. This is a great build [Ben], thanks for sharing the details with us.

Laser Cutting Solder Stencils

Do you have access to a laser cutter? If so, you can use [Riley Porter’s] method to
cut your own solder stencils
. He starts with the Eagle files and exports the Dimension and tCream layers to a PDF. That file is then processed using Ghostwriter, Gview, and finally, Corel draw. The result is a 1200dpi file to feed to your Epilog laser. Now you’re ready to
stencil on the solder paste
and
populate the PCB
.

He’s right about the Eagle PDF export causing problems, I’ve been using Inkscape to open it and save in a format Corel understands.The main thing he’s wrong about is the actual sizing of the cream outlines. You can see a lot of his pads actually overlap, this will allow too much solder to be deposited and cause bridges during reflow. Due to the kerf left by the laser cutter you need to shrink the outlines by a few mil. I usually go into the DRC Mask section, and on the Cream part I set a max of 10mil and a percentage of 20% or so. Then export the cream layer.For 2mil mylar on a 45 watt laser, I tape the plastic on smooth birch plywood and cut the outlines in vector mode with 8% speed and 3% power. That seems to eliminate most of the melting and rough edge problems people complain about with mylar. It actually sticks most of the chads to the plywood, so when you pull off the stencil it automatically weeds most of them.Here’s a picture of one stencil I made:http://www.flickr.com/photos/macetech/3311194156/And here’s a video of cutting a stencil recently:http://www.twitvid.com/5F80B",

Mylar is better in the long run for multiple uses (meaning multiple days). But the paper does not melt and edges are 100% straight.@mrgoogfanIf this is all you used the laser for then I would say No… I use mine for alot of different stuff check out my flickr stream.http://www.flickr.com/photos/rileyporter/",

Researchers at the University of Liege have developed
an algorithm to separate movement from background
. They call it ViBe and this patented piece of code comes in at under 100 lines of C. Above you can see the proof of concept shown by hacking the code
into CHDK
, a Canon PowerShot alternative firmware. The
package is available
for non-commercial use and might be just the thing you need to get your project to recognize where it needs to
serve the beer

It is probably doing something based on regions and tunneling down to each pixel change.",

Arduino Based Multiboot Cable For Game Boy Advance
|
Mike Szczys
|
[
"Nintendo Game Boy Hacks"
] |
[
"arduino",
"game boy advance",
"gba"
] |
[Steve] wanted to do some ARM development and set his sights on the Game Boy Advance as a development package. In order to get his code onto the device he build
an Arduino-based communications cable
. It is necessary to have a microcontroller involved because the GBA uses a peculiar 16-bit serial communications protocol. This cable is an adaptation from the
8051-based cable
developed by [Matt Evans] several years ago. [Steve’s] got it working by porting the 8051 assembler over for the Arduino, but we’d recommend adding a level converter to his hardware setup to step down from the Arduino’s 5v logic to the 3.3v logic the GBA expects.
He didn’t make up a wiring diagram, but in the code comments [Steve’s] laid out the connections as follows:
Arduino 8 to GBA SO
Arduino 9 to GBA SI
Arduino 10 to GBA SD
Arduino 11 to GBA SC
That’s it, follow the README in his source code package and you’re on your way to some ARM development.

As the first poster said, you are limited to 256K though.. so it’s not like you can upload commercial games although some programmable carts do use a similar cable + multiboot program to write rom images from a computer. I wrote a multiboot prog that dumps the rom + eeprom/sram from the cart in the slot over the serial port Back in the Day ™…Oh, having this sort of cable is also useful for sending debug messages too.. especially if you still haven’t work out how the display modes etc work.",

[Sparky] notified us of his hack to
allow interaction with the core
of an Aldi GO Cruise 4300 GPS Windows CE OS. All that’s required is a few programs and registry edits to the GPS, which anyone can accomplish within a few minutes. But we suggest you go slow and double-check your work; nobody wants a bricked system. After you’re done you can run such great programs like the one [Sparky] suggest for 4WD enthusiasts,

USB is convenient and that makes it desirable in many many projects. [Simon Inns] has the process down and is sharing it with his recent
PIC based USB tutorial
. Prompted by requests for help on the matter after having published a post about
his Commodore 64 interface
, he set out to detail the particulars when it comes to using the PIC 18F family as USB input devices. This example uses a PIC 18F4550 with the circuit built on a breadboard. There’s not much required here, an oscillator, a few passives, and a USB B connector. The magic really happens in the code. Take a look at this well-written guide and give it a try with your next project.
Don’t need USB? [Simon’s] game hack,
the Ultimate Simon
is always worth another look too.

I’m building and testing it but the device just didn’t work as expected.As reader Jason of your article on WFF has pointed out, the crystal oscillator could not necessarily be 20MHz.

I’ve already changed the following line in main.c__CONFIG(1, USBPLL & IESODIS & FCMDIS & HSPLL & CPUDIV1 & PLLDIV5);to__CONFIG(1, USBPLL & IESODIS & FCMDIS & HSPLL & CPUDIV1 & PLLDIV6);to take into account the different oscillator frequency.I’m wondering if I should use different capacitors in lieu of the 15pF as you are using? Is this what made my device not function?And here’s another issue I’m stuck to –I have tried registering in the WFF forum. I’ve completed the process except for the activation. It seems some thing wrong because I cannot receive the activation email from your site.My user name is min2max and the email used isloadcom@sina.com.

Ask Hackaday: Now A Regular Occurrence
|

"Ask Hackaday"
] |
A while back,
we announced that we would be bringing new features to Hackaday
. One in particular that garnished a lot of interest was our question answer type thingy. Well, in case you hadn’t noticed, that has not happened yet. Without divulging too much into the secret machinery that lies underneath Hackaday, I’ll just say that we(the writers) don’t necessarily have control over all aspects of the site. An example would be the copyright. Yes, we finally got it updated. Thanks for all of your emails. No, none of us had access to that part of the site, so don’t bother letting us know how simple that change should have been.
We are as eager as you to see some good ideas and good feedback flowing through this site, so we’re going to start a regular post, entitled “Ask Hackaday”. This isn’t entirely new, we’ve
done it before
actually. This is just to let you know that we intend to do it regularly, and to set some ground rules. “Ask Hackaday” will mostly center around you, our readers, and your ideas. We will publish a question, and possibly our thoughts, but the main content will be your responses. We have a huge collective of intelligent creative readers and it would be a shame not to tap into that pool of knowledge. When you are offering an answer, be thorough, give details, and please be kind.
Send your questions to askHAD@hackaday.com for consideration. They will be chosen based on a complicated system of random number variation involving furry woodland creatures and how we feel at the moment that we read them. Do not get offended if you question does not get published. We get tons of questions already and we don’t intend to publish them all.

I WAS a loyal viewer to the “Instructables” site. That was until I woke up one day to find their new and annoying REGESTER/LOGON feature. Yes! JUST to view the complete illustrations/next picture in an Instructable one had to register and logon. It got worst – After a few months that same LOGON morphed into a “PAY to VIEW Privileged content” in which those who PAY get the complete article and step-by-step instructions. I understand maintaining a site isn’t free – however, that site is swamped with advertisements. The worst is what they want to charge for a yearly membership. It looks like they went from creating something they loved to do, and now went for total profit. PLEASE KEEP THIS SITE FREE!!!",

[XenonJon] got a lot of attention for a skateboard/segway style balancing platform he took to the Makerfaire in Newcastle. He decided to try to
build it the cheapest and easiest possible way
in an attempt to help others build their own. The build is documented very well, however you have to email him to request the code for the Arduino. Maybe after enough requests, he’ll just pop it online. We thought this looked familiar, so we searched the archive and found
this very similar setup
from back in 2005. Unfortunately, that project page appears to be gone now.

Many do not openly publish code for self balancing vehicles because someone in this killjoy society may sue them if they fall off. They are not being pretentious pricks.My website openly acknowledges every single segway and seg-skateboard builder I have found on the web. There are very few skateboard designs that actually work well. I am seeing how far I can go and documenting it.The video you have included is the first showing this particular version of my current machine being ridden, and that includes on my own website. It went on Youtube one week ago.I did not submit this to Hackaday either, they found me.However if sending me a message so I can email you my (free) code, based on a couple of years of work, is too much trouble for you Mr xorpunk then you are really pretty unlikely to have the attention span to build anything like this.If you can do better, be my guest – do something constructive.You have put up the wrong video. The correct one is here:http://www.youtube.com/watch?v=engi16bLJe0&feature=channelI had so much interest, much of it from teenagers interested in electronics, when I showed my (expensive and tricky to build) machine (the video you have shown), that I have redesigned it to be as affordable as possible, as simple as possible to construct, and now runs with an Arduino micro, i.e. easiest to program. I have done this specifically to encourage people to have a go, widen the interest and expand this community of enthusiasts – I would call that constructive not pretentious. I am male though so I do indeed have a prick.There are many other self balancing designs out there. Most are Segway style. Very few if any run Arduino code. Some balancing small robots do. The only reasonably workable twin wheel steerable skateboard I have seen with small wheels under the deck was/is the Emanual 1, which I have acknowledged clearly in my instructable. This used infra-red distance sensors each end. However if you know of any such designs with a hidden flat Lithium battery pack in the deck, wheels under the deck not sticking out of the sides, steered (not moved along) by a wireless Wii Nunchuck, light enough to be carried in one hand, that will go over rough surfaces, that have a >20mile range, then please do let me know so I can improve mine.If you want to just go fast, you need a standard electic skateboard. They go up to 35mph and there are several makes.If you want a normal skateboard, fine, none of this will be of interest to you.John",

POV Clock Inside Acrylic Block

"clock",
"POV"
] |
This gorgeous
persistence of vision clock
was built a couple years back by [mb1988]. The housing is made of acrylic with a hard drive motor mounted in the center of the back panel to spin a PCB. The two-sided circuit board is home-made and includes a battery for power, ATmega32 for the brain, 32 LEDs, four display drivers, and a real time clock module. The spinning hard drive motor is nearly silent and already has threaded mounting holes on it. [mb1988] uses an optoelectric sensor to sync the display with the rate of rotation. The forum post includes download for the code and hardware details. Don’t miss the demonstration after the break.

By Popular Demand: The OK Go Rube Goldberg Machine
|
Mike Szczys
|
[
"HackIt"
] |
[
"OK Go",
"rube goldberg",
"Syyn Labs"
] |
We’ve received many tips regarding the OK Go video that features a Rube Goldberg machine. If you haven’t seen it yet,
check out their video
after the break. This is the rare instance when a YouTube video features an audio track with the full endorsement of the artists that recorded it.
Our first thought when watching this? Who are the lucky dogs who got paid to design and build that contraption? You don’t have to scratch your head over that one, the Band has posted a four-part video series talking about the machine and documenting the design meetings and build process (those videos also after the break). The engineer artists at
Syyn Labs
were tapped to pull off the meticulous mayhem and we think they did a stellar job. There’s been a lot of press about the work, but
our favorite was over at Wired
because it details the process, not the end product.
The best part about Rube Goldberg Machines is that asking “why?” is the wrong questions. The sheer joy of the build makes
taking over a house
or
over-complicating the fulfillment of hunger
worth it.

RoBo Blower Sure To Become Stephen King Novel
|
Mike Szczys
|
[
"Robots Hacks"
] |
[
"RoBo Blower",
"snow blower"
] |
Snow removal ranks right up there with laundry as one of the least-enjoyed chores. [Herb Spencer] sought to automate the process while terrifying his neighbors as the same time by building a robotic snow blower,
the RoBo Blower
. The heavy lifting is still handled by a gas motor which propels the snow auger. Two batteries power the electrical system that takes commands from a remote control, moving the show chute and managing the navigation. He’s done what he can in the way of safety, adding a grate at the front, flashing light atop, an operator-controlled horn, and kill circuitry (to shut it down, not to kill the unsuspecting). All of this is wrapped up in a nice package, especially when compared to the
snow blower push platform
from last month.
Maybe next year he’ll work on making it
autonomous
? Take a look at the RoBo Blower clearing a driveway after the break.

All Terrain Roomba

This little rover gets around on rough terrain pretty well. [Dean Segovis]
built it using parts from a Roomba
. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this
Rocker-bogie suspension
. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of
the Roomba’s
rough-and-tumble outdoor cousin.

[Daniel] wrote in to show us the project his group has been working on. It is a massive display wall consisting of 28 projectors and 30 computers. With a resolution of 7168×3072, viewing a 13.3 gigapixel image is a treat. That treat is made even stronger by the fact that navigating the image is done multitouch style with a touchless system built from web cams. We’ve seen lots of projects come out of the
NUI group
with similar interfaces, but none that used the webcams like this. Usually, the webcam is detecting some kind of interaction between the person and an infra red light source. Maybe that is happening here and we just don’t see it.

[Viktor], one of our favorite avid hackers, has been playing around with 1-wire systems all this month. What started out as a
MicroLAN Fonera
has turned into an
iButton interface
, to a 1-wire
powered hub
, and finally a 1-wire
character driven LCD
. Anyone looking at 1-wire systems or OWFS could surely benefit from his testing.
However, if you still haven’t gotten your fill of 1-wire goodness, let us remind you of the 1-wire
HVAC
and
IPv6 to 1-wire protocol translator
.

Are you still using heat sinks and fans to cool your computer? Lame. Tearing up your property to bury geothermal coils is definitely the way to go. [Romir] has been working on this for about a month and is just getting back data from the first multi-day tests. Take some time to dig through
his original post
. It includes something of a table-of-contents for the 35 updates he’s posted so far.
Closed loop cooling seems to be trendy
right now, we just didn’t expect to see a system this large as part of a personal project. The
last one we looked at
used just six meters of pipe.

I’d love to extend the coolant lines the fridge to the condenser so that the condenser could be outside, and submerged in a heat transfer tank with water as it circulates through the pool filter. The same idea would hold true for the air conditioning.On the one hand, the pool water flowing so quickly would much more efficiently cool the condenser coil and I’ll bet the fridge would run more efficiently.On the other hand, the corrosive effects of the chlorine would probably play so much hell with the system as to remove all benefit.Frustrating problem.

I used to live in Michigan where winters get very cold, and it annoyed me that electricity was used to create a cold spot inside my fridge, inside of a house that I used electricity to heat, in an environment that was cold.A truly “green” fridge would feature a couple of filtered dryer hoses that could connect to the outside world. Any time the outdoor temp was lower than the fridge thermostat setting, the fridge would circulate outside air (with dampers and a low power fan) in preference to firing up an energy-intensive compressor. Needless to say, this model of fridge would only sell in higher latitude areas.I now live in the desert in the Southwest. It’s retarded to pay $$$ to pump heat out of the interior of my fridge, into my living space, and then pay again to pump the heat from my living space to the outdoors. A green fridge for this area would feature a couple of hoses that would let me vent waste heat directly outdoors.
