RoboThespian: Chuck E. Cheese Entertainment Comes Home

[ "animatronics", "blender", "chuck e. cheese" ]
Remember your eighth birthday party when the animatronic band at Chuck E. Cheese sang happy birthday just for you? Now you can enjoy this any day of the year with RoboThespian . The complete animatronic platform has been modeled in Blender 3D . Animating the robot is as easy as producing an animation from its digital model. Lip syncing is generated automatically, with the handles to the right of the model’s head controlling facial expression. Using Blender as a choreography tools is brilliant.  We’re hoping someone will incorporate this technique in their Halloween shows this year. [Thanks Rob via BlenderNation ]

Shiftbrite Coffee Table

Here’s a project we’ve been wanting to do for a while. Over at macetech.com they’ve posted an LED coffee table that uses a 9×9 RGB LED grid . For the LEDs, they used the shiftbrite modules we’ve seen before . The table is capable of displaying pre written patterns as well as accepting patterns from a computer via bluetooth. They’ve set it up to connect to a twitter feed and display to a live cam on their site. Though we would love to reproduce this, we need a little more justification than “ooooh, shiny”  for the funds involved. Anyone want to donate 100 shiftbrights?

[Antonb] added 10-bit encoding to a standard servo . He’s removed the potentiometer, separated its shaft and used it to rotate a small magnet. By sandwiching an AS5040 rotatory encoder IC into the servo’s housing he can now measure the precise orientation of the servo horn. This is made easier by his tiny breakout board for the chip. If you want to layout your own PCB you can download the EagleCAD files for this device . Take a look at the final product in the clip after the break.

Bring The Crane Game Home

[ "arduino", "claw", "crane game", "gantry" ]
Everyone’s familiar with the quarter gobbling crane games. More often than not there’s a child nearby begging a parent for more quarters so they can try their hand at the toy-snatching claw. [Marc.Cryan] put his quarters to a better use by building a home version of the crane game . [Marc] installed a gantry in an archway of his house.  The crane trolley rides on this gantry and uses a spool to raise or lower the tether for the claw. Winning copious style-points, he used the case of an old mouse to form the claw. An Arduino controls the different motors in the system and a toy was repurposed to act as the controller. As you can see after the break, it’s more fun than the cinema-lobby version of the game and your kids can play with it for free. [youtube=http://www.youtube.com/watch?v=UggcYNUNqn0]

PC-based USB oscilloscopes are fast becoming all the rage. [Matt Sarnoff’s] Terminalscope takes the reverse approach, adapting an oscilloscope into a full serial terminal . You may have seen something similar before in the Dutchtronix/SparkFun O-Clock , but [Matt’s] project goes one further by adding a PS/2 keyboard port for full bidirectional serial communication, and with much sharper display resolution to boot. The mostly VT-100 compatible Terminalscope is built around two AVR microcontrollers: an ATmega328P runs full-tilt to generate the video signal and handle serial I/O, while an ATtiny45 handles keyboard input to avoid interrupting the ’328’s duties. Rather than vector trace each character, a raster-scanning approach is used: the beam follows a fixed X/Y path (like a television), while modulating the Z input (beam intensity) to form an image. The device can be connected to a PC via serial port or USB-to-TTY adapter , or directly to another microcontroller to debug serial output. We recently showed an oscilloscope being used as a multichannel digital logic display . The Terminalscope provides yet another use for this essential bench tool and could nicely round out a “poor man’s” testing setup. The schematic and full source code are available for download.

More Cellphone Controlled Door Locks
Mike Szczys
[ "Cellphone Hacks", "Security Hacks" ]
[ "lock", "wrt54g" ]
[Tom Lee] and his colleagues just moved to a new office. The doors are setup like a security checkpoint with electronic strikes and buttons on the inside to allow entry. The button simply completes a low-voltage circuit, activating the strike which made it quite easy to patch into. They build an interface board with a small relay to complete that circuit. As we’ve seen before, Linksys routers have plenty of extra room in the case so there was no problem housing the new circuit in this tiny network device. Now [Nicko] and his friends can use a custom app to input an access code or to verify a device ID from a cell phone and gain entry. The door still has keyed locks in case of a power outage. In fact, the only change made to the system was the addition of two wires to the “door release” button as seen above. See the one-touch device ID authentication in the video after the break. This hack is similar to the GSM door entry from last year. In this case, the phones are communicating with the door via web interface and not the GSM network.

Add Pause Button To The Atari 2600

[ "classic hacks", "home entertainment hacks" ]
[ "atari 2600", "pause" ]
We’re sure that if there had been a pause button on the Atari 2600 people would never have moved on to next-generation systems. Now you can dig the gaming relic out of the closet and pause your Atari games for some good old om nom nom .This hack is from the same person who pulled off the Atari 2600 jukebox . By reverse engineering the signals used on the Onyx Jr. , which has a pause button, the halt method became clear. The problem is that the Onyx Jr. uses a different processor than the 2600. A different processor means a different pin-out, and now the clock signal needed to synchronize the pause cycle was missing. But eureka, an abstract source was found. The ready signal from another chip can be used to judge the state of the processor. The small PCB above now interfaces with the Atari 2600 in order to patch in the pause circuit.

[ "18f877a", "guitar pedal", "loop", "pic" ]
This guitar pedal can record, playback, and modify samples. [Colin Merkel], also know for his work on electronic door locks , built this to replicate some guitar effects he heard in recordings. By tapping the button at the bottom with your foot the device begins recording. Another tap stops the recording and starts the loop. That’s where the rest of the controls take over, with settings to adjust the speed of playback, volume, and the type of playback looping. The video after the break gives a great demonstration of these features. [Colin] built this around a PIC 18F877A with a 256k RAM chip to store the sample. There’s a bunch of other components that go into this and we’re dumbfounded that he built it on protoboard. This would be a multi-breadboard prototype for us and we wouldn’t think twice about laying out and etching our own PCB. He admits that the point-to-point soldering stretched his skills to the limit but he doesn’t say how many hours it took to get the circuit up and running. This is a great addition to the cool guitar pedals we’ve seen here. [youtube=http://www.youtube.com/watch?v=R1ZOEZFlNzE]

Hackaday alum [Will O’Brien] has been doing some cellphone integration work . He recently picked up some Motorola c168i cellphones from eBay. It turns out there is a serial port that uses TTL communication with a standard head-phone jack as an interface. [Will] soldered up a connector and used a USB to FTDI cable to interface with the phone. To his surprise he was able to read off the stored text messages even though they were PIN protected in the phone’s operating system. The messages on these units were trivial but this is another example of the importance of clearing your data before discarding your devices.

DIY Aluminum Heat Sink Casting

[Peter Wirasnik] has been casting his own aluminum heat sinks . He’s working on capturing the heat from a car’s exhaust system and turning it into electricity, kind of like the candle generator . In the photo above a standard heat sink is bolted to one side of a Peltier cooler with [Peter’s] own casting on the bottom. That casting will connect to the exhaust pipe and transfer heat to the Peltier while the other heat sink keeps the opposite side relatively cool. What results is a voltage between 600mV and 1V. We’re not quite sure what the end product will be but the casting process is fascinating. He carves the shape of the piece he wants to cast from Styrofoam and embeds it in a box of sand. He then melts salvaged aluminum in a cast iron frying pan using what looks like a propane torch. Once molten, he pours the aluminum into the mold and it burns away the Styrofoam as it fills the void. A little cleanup and he’s got the heat conductive mounting bracket he was after.

Some researchers from Oxford University have come up with a way to produce high-speed video from a one mega-pixel camera. They’re calling the method Temporal Pixel Multiplexing . This method adds a digital micromirror device in line with the camera lens. These chips house over a million mirrors and can be found in home theater projectors. By placing one in front of the digital camera, a longer exposure can be used while the DMD redirects the light. This way, one high-resolution image actually contains multiple frames of lower-resolution video. The video is still decent quality and, at a far lower cost than common high-speed video equipment, this is a worthwhile trade off. [Thanks Andrew via NewScientist ]

[Brad] has continued working on the Super Pixel Bros game . We saw a glimpse of this a few months ago but he’s added a lot since then. The game now has enemies; one type is similar to Bullet Bill , another type drops from the sky and walks toward you, kind of like a Goomba . Game play is quite responsive and it’s amazing what he has accomplished with such low resolution. In the video after the break [Brad] mentions that a friend is working on sound effects for jumps and block breaking. We’re assuming that the audio track in the background is already coming from the LEDBOY speaker. Which reminds us, if you haven’t checked out the hardware , do so now. That enameled wire mess makes us shudder just a bit. There many be a kit version coming that will save you the point-to-point soldering madness. If that’s part of the fun for you keep an eye out for the forthcoming release of the hardware schematics. [youtube=http://www.youtube.com/watch?v=Avvba3prLlc]

These boxes, called Flexi Knobs , work like a wireless Atari paddle and mouse rolled into one. Each has a rotary encoder that can also be clicked like a button. On the inside is a wireless optical mouse which controls an on-screen cursor which matches the color of the knob. In the video after the break you can see these are being used as midi controls. Each cursor can be locked onto a virtual knob, giving it a physical interface. Because there are several units being used on one machine this creates something of an abstract multi-touch system. This would make a nice interface for other applications with a plethora of settings, like Blender . [youtube=http://www.youtube.com/watch?v=UuUjf-c6L6U]

This is interesting, as he doesn’t have to place his hand on the mouse any more, he just plops it down on any surface and starts mousing.  He claims that it is helping his twitch reactions in gaming as somehow it requires less force, but we still see the circuit and batteries mounted on the back of his hand, so we’re not sure how it is helping.

[Eric] built this robot for the 2009 Robocup Jr. competition . The game ball has IR LEDs inside of it and this little bot uses eight IR detectors for tracking. Four motors mounted perpendicular to each other provide locomotion. Since this would normally have you traveling in circles, he used some omnidirectional wheels walled Transwheels . As you can see, they have small rollers built-in and allow movement in any direction if the motors work together. A couple of L298 controller chips handle the motors. [Eric] wrote a program to calculate the PWM necessary to drive the controllers and to coordinate movement of the wheels. Don’t miss the demo videos after the break and, if you’re not a fan of wheels, stop by and see the bi-pedal soccer robots .

Reader [Hjhndr] ran across an interesting set of tests and wanted to know if they’re brilliant or just a load of bull. We’re not making the call on that, but the tests on a Steorn Orb motor replica are worth looking at.Keep in mind, people used to think the earth was flat and scientists of the time would have sworn up and down that’s the way things were. The Steorn Orbo is a motor that generates more power than is put into it. At least according to Steorn Limited that’s what it does. An independent panel of scientists said otherwise a few years back but that didn’t stop the company from showing off the concept a few more times, most recently a showing in Dublin ended this month. So anyway, [Jean-Louis Naudin] took what he saw from those demonstrations and built a replica. He’s made several papers about the principle as well as his testing available online.

Early hacking eduction is important if they want their future projects to be regular Hackaday features. The crushing power is provided by a solenoid pneumatic ram. As seen in the video after the break, the can goes in the door on the left, is crushed, then drops through a slot. [Jeff] had fingers and hands in mind when designing this and included a few safety features. The “crush” button is locate on the opposite end from the can slot, there is a kill switch to disable the solenoid, and a keyed switch to shut the whole apparatus down.

This hoodie senses your heartbeat and uses it to control Life . Conway’s Game of Life, popular in all kinds of electronics projects , uses a grid of cells coupled with a set of rules to mimic the life and death of simple organisms. This iteration displays the game over your own heart, then taps into your heart rate, resetting the game at the beginning of each cardiac cycle. We guess you could say that Life goes on only if you do not. The EKG circuit that detects the heartbeat is made up of an IR transmitter shining through the tip of your finger to a receiver. An ATmega168 running the Arduino bootloader controls the EKG circuit and resets an ATmega48 which is responsible for Life. [Joe] admits that this is overkill but he’s currently without an AVR programmer; he went this route to make it work.

This track is awful, someone skip it! This project does just that with a wave of your hand. A laser beam shines across a room and, when obstructed, it sends a command to an iPod. One wave pauses playback, two waves skips to the next track, and a constant obstruction jumps backward one track. They’re using a textile-compatible electronics platform called Schemer . This is the first time we’ve run across this product which uses a modular system to connect devices via a 1-wire communications bus. No matter what hardware you use the concept is what interests us. There’s no shortage of iPod remote projects to draw on as examples. This method seems a bit more fun than banging your head for track changes or slapping wildly at an over-sized remote .

[youtube=http://www.youtube.com/watch?v=iC9l1jO7Lyc] 3 breast pumps, a Meggy jr RGB (slightly modified) and copious amounts of alcohol. This sounds like a typical weekend at HAD headquarters, but it is in fact the parts list for the Drink Making Unit by Evil Mad Scientist Laboratories. Created for the upcoming Barbot 2010 event, this unit is a cocktail mixer. Load 3 liquids in, program the Meggy and you can push a button to dispense. We are pleased to see how much they modified off the shelf components to make this happen. Yes, there could be major improvements like mixing, more liquid reservoirs, and a better cooling system, but we think this thing is pretty slick.

Binary Clock Uses DS3232 RTC
Mike Szczys
[ "clock hacks" ]
[ "arduino", "binary", "breadboard", "clock", "ds3232", "rtc" ]
[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece . The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 real-time clock which automatically compensates for temperature to achieve very accurate time keeping. We like the super-cap circuit he added to keep the RTC running if the power is cut. Is an Arduino overkill here? Well, the code is certainly not filling the 16k available on the ATmega168. At $4.32, the $1-2 you could save by using a lower-grade chip is not worth having to rewrite the code developed during prototyping. [Kenneth] also mentions that these projects usually only hang around for a few weeks before they’re re-purposed for the next endeavor. Take a look at [Kenneth’s] superb hardware walk through in the video after the break.  If you’re a fan of clean breadboarding, he’s also made a time-lapse of the circuit building process.

[Andreas] found that his home theater PC would not boot one day . Oddly, if he disconnected his HDMI cable from his TV, it would boot fine.  While most of us would have dug into the PC, he realized that it was a signal from the TV that was incorrect.  Luckily, LG had included a full schematic with the TV.  What he was able to figure out, using a home made snooper was that the EDID eeproms had somehow become corrupted. Not to worry, [Andreas] slapped together a full blown I2C interface and prepared to reprogram them with the correct data.  He noticed, however, that the eeproms were write protected.  On a whim, he decided to write to them any way and found that it was successful. He has some theories as to why they were writable, but says that he doesn’t want to pull the TV back apart to confirm. [thanks evlapix]

[Brandon Meyer] spared no expense in modding the Catch Phrase game to use custom word lists . The altered version of the game, normal sold for around $25, now comes in at a whopping $230! That’s because the internals were gutted and replaced with an Arduino, 20×2 LCD display, and some other interesting bits. The device now features an SD slot for storing your own lists and a USB port for programming. At first glance we were hoping some simple EEPROM hacking had unlocked the secrets of the device but that wasn’t he case. We’d love to see some more economical versions of [Brandon’s] prototype. Perhaps reusing the original LCD, replacing the Arduino with the ATmega168 that makes up its core, and using a diy SD cradle for a card reader. So yes, this version is a bit of overkill but still very nicely done! [Thanks Zoidberg]

The camera is pointed into the salvaged camcorder lens where the fine tuning is done. His first iteration was just taped to the desk with a small hand flashlight illuminating the subject. He upgraded that setup by building a LEGO enclosure and changing to a much brighter light source.

[Barry] shared his postulation on how electronic key impressioning works ( google cache ). You may remember his foil impressioning demo from earlier in the month, but now he’s addressing a piece of news we must have missed. Apparently, a handheld impressioning device is about to hit the market that can tell you the key codes for a lock in a matter of seconds. [Barry’s] guessing at how this is done from his experience with a similar device aimed at car locks. When the circuit board seen above is inserted into a lock, it completes a circuit between the lock housing and the wafer. The firmware monitors the conductors on the tip of the PCB to calculate how deeply the cut should be and at what point on the key. This would be fun to try with a homemade PCB, any idea how to deal with wrapping traces around the edge of the board like that?

[Banfield Design] has put together this instructable on how to upgrade or re build a head mounted display to be more immersive and add features.  Though you can already buy glasses style viewers for your media devices, they can use some upgrades. For one, you have to supply your own sound, and putting headphones on, over bulky glasses can be painful on your ears. Another area that could use improvement is the light that comes in around the glasses. The current trend is to make them as small as possible, but that tends to let your peripheral vision see the outside world. [Banfield design] wanted to make them more immersive, so he built them into some ski goggles. This not only helped block the light, but allowed for an over the ear style headphone assembly which is much easier on the ears. A functional improvement came next, by adding a webcam front and center. He could now switch between a live feed of his environment and whatever other inputs he wanted. This could be really fun with some augmented reality. He has a list of future improvements, but he doesn’t mention adding a second camera for stereoscopic viewing of his surroundings. Why would you do that? because it would make augmented reality much cooler .

Spectrum Analyzer Wedged Into A Cellphone

[Miguel A. Vallejo] wanted a portable spectrum analyzer for the 2.4GHz ISM band. No problem, there’s modules for that are easy to interface with a microcontroller and LCD screen. But carrying around a black project box doesn’t exactly scream ‘cool’ so he fit his spectrum analyzer inside of a cell phone . This made a lot of things easier for him; he already had a few old phones, he was able to use both the original battery and the original LCD screen, and a lot of the mounting work is already done for you. The only challenge was to fit his custom circuitry inside. By hacking off part of the CYWM6935 module and cutting some protoboard in the same shape as the original PCB he managed to get everything into this tiny portable package. Now he’s looking for a way to incorporate a charger, and an on/off switch. If you don’t have an old cell phone sitting around you can try building a spectrum analyzer that uses a character display . But we’d suggest hitting up your friends for their old cellphones.  The screens are used in all kinds of fun projects .

Chip And Pin Broken And Other Security Threats
Mike Szczys
[ "HackIt", "Security Hacks" ]
[ "cyberterroism", "man-in-the-middle", "pin and chip", "security" ]
Another exploit has been found in the Chip and PIN system.  The exploit is a man-in-the middle attack that wouldn’t take too much know-how to pull off. You can watch the BBC report on the issue or check out the paper (PDF) published by the team that found the vulnerability. A stolen card resides in a reader that connects to a dummy card via a small cable. When the dummy card is inserted into a card reader, any PIN can be used to complete the transaction. The chip on the original card gets confirmation that the sale was completed via signature and the vendor’s card reader gets confirmation that the pin was correct. The UK based Chip and PIN system seems like a great idea, but it has had its share of security loopholes . This makes us wonder how hard it is to roll out security patches to the hardware readers in the system.  Obviously this needs to be patch but does it take a technician visiting each terminal to flash an upgrade? Switching to the topic of wide-scale attacks, we caught the NPR interview with [James Lewis] on Wednesday when they discussed the growing threat of Cyberterroism. He feels an attack on the US electrical grid is currently the biggest threat and will happen in the next ten years. Obviously taking the grid down would endanger lives and bring things to a standstill; traffic lights, refrigeration, heat, etc. We’re just glad that when asked if he thinks there is already malicious code residing in the control system, he doesn’t think that’s the case.

This project, by an unknown hacker, patches into an electric typewriter and uses it as a Teletype . An AVR ATmega168 microcontroller patches into the key matrix of the typewriter which allows it to artificially type. Now, data can be sent over a serial connection to the AVR for output on the typewriter. We’re not quite sure what this is going to be used for.  We’ve seen hacks like this for Twitter reading in the past but he makes no mention of that type of use. Personally, we’d like to have this just to “print” out the occasional letter. Typewriters are so rarely used these days it would be a bit peculiar to get a letter that has the dimpled impressions associated with slamming a die into a piece of paper.

[Brad] has created the ZephyrEye as an electronic command and communications device for real-life games . Each player carries around their own unit. The ZephyrEye has a GPS module, Xbee module, LCD screen, and control buttons. This allows a player to setup one of several different games, map out the game field including base locations and flag locations, and monitor a time limit and scoring. Other players can join the game in progress. The best part? The GPS modules report tracking to each handheld and act as radar for your team and the enemy team. We’ve got a couple of demo videos after the break. Words can’t describe how delighted this would have made us back in the day. We don’t play outside with the other neighborhood kids anymore (insert dirty-old-man joke here) but that might change just because of this device. We may end up joining [ Barney Stinson ] for some amazingly awesome laser-tag games after all.

[Zhanx] has since migrated from the Arduino to a BeagleBoard which you can see perched atop the body in the video after the break.

There’s a simple hack to use your Motorola Droid phone as a USB host . It is a hardware-only hack that doesn’t require you to crack open your phone, root it , or even to change firmware (although device drivers in the stock Android image may be quite limited). The dongle above is used as a key to enable the mode while the phone is booting. This was repurposed from a car charging cable by removing the wires and resistor and shorting the resistor pads. Once the phone is in host mode the dongle is swapped for a simple USB-mini to USB-A socket adapter, built from two cables you probably have lying around. Now you can plug in any device you want.

The method is wicked-hard, involving removal of the chip’s case and top layer, then tapping into a data bus to get at unencrypted data.

[youtube=http://www.youtube.com/watch?v=lHpZ5tM7sN8] We just found this great portable multitouch rig called the portatouch . Made by a user at the NUI group website named [portatouch], this system uses a stripped down LCD as the display with IR LEDs edge lighting a touch surface in front of it. A camera mounted below the LCD picks up the reflections of the LEDs and converts it to touch points. While the implementation isn’t anything new, the package is really great. If you want to learn how to set up the technical side of it all, head over to the NUI group website and you’ll find all you want. We would love to see a more detailed breakdown of his rig though. The portability and quick construction are fantastic and seem like they could be reproduced without a ton of custom work.

‘tiny’ Power Supply Monitor
Mike Szczys
[ "classic hacks", "Tool Hacks" ]
[ "attiny13", "AVR", "hd44780", "high voltage", "hvsp", "power supply", "psu" ]
[Manekinen] built a power supply monitor based around an AVR ATtiny13. Voltage and amperage are displayed on a 16×2 LCD character display (we’re not sure what the third number is… samples per second?). This is no small feat considering that the tiny13 is an 8-pin chip. He makes it happen by using the pins for both LCD control and ADC input. To make this happen the HD44780 compliant display is used in 4-bit mode. Check out the video after the break and hit up the non-translated page if you want to download the source code and PCB artwork. A note of warning, he’s using the RESET pin for I/O which means once you burn the fuses you’ll need a programmer that has High Voltage Serial Programming capabilities if you want to reprogram the chip.

“Everyone needs a hobby,” they tell us. For the blogger mysteriously identified only as “R,” that hobby would be an almost fanatical nostalgia for the Commodore 64 computer . At first we thought this was a fan community site, but apparently it’s all the work of a single person. [R] has tweaked, extended, repackaged and resurfaced this 1980’s icon in nearly every imaginable way. They tend to gloss over the technical aspects of these mods, but that’s okay – the C64 is such an exhaustively documented system now that the site dwells mainly on the aesthetics and meaning of these reborn devices. The 64 has made an indelible impression on electronic music , and the machines are still sought after by collectors, composers and circuit-benders . [R] pays homage by housing these vintage systems in styles reminiscent of even vintage-er synthesizers . Any one of these would warrant a post here, yet there’s a whole collection to browse. Check it out!

The base model sells for the same $99 and appears to have the same specs as the original but for $30 more, the GuruPlug Server PLUS moves to 2 Gigabit Ethernet ports, one eSATA connector, and built-in WiFi and Bluetooth. All of this for $129 and it only pulls 5 watts? Wow.

[Oliver] has been doing some work to use his TI ez430 Chronos wristwatch for some home automation . He’s working with a RF controllable lightbulb adapter which operates in the 433 MHz band. A dirt-cheap breadboard-friendly transmitter is available from Seeed Studios and he uses this in conjunction with a computer and an Arduino. Before the trolls get to their thing, YES, this is incredible overkill. But remember that he’s prototyping. We hope that if he intends to actually use this setup he’ll migrate to something like an ATtiny2313 running V-USB . Better yet, you should be able to tap into the watch’s companion receiver and cut the computer out completely. If you’re easily amused you’ll appreciate the video of a light turning on and off after the break. If you’re a little harder to please then take a look at Oliver’s methods of using Python processing for the watch’s data. Ok, now we’ve seen this watch turning on lights and unlocking doors . What else ‘ya got?

The original PUSH competition was only for UK members, but now Nokia has introduced the ‘ Mod in the USA ‘ N900 PUSH competition. Similar to the original , anyone (within region) can submit a cool mod, hack, useful creation that would use the N900. Winners will be selected, and thats when the differences start. There will be a $10,000 for 1st prize, and smaller prizes for 2nd and 3rd. Plus a trip to Vegas to showcase the 3 winning hacks at CTIA 2010 as well as funding, N900s and support to build the mods. Don’t have an idea but still want to try? They have a discussion group to get the juices flowing, or you could always discuss in our comments.

At least this isn’t disgusting like the LED nipple ring . Chandelier your wife will never let you install This 300 LED chandelier uses epoxy coated wires draped around the light ring to resemble a more traditional crystal light fixture. It’ll still be a hard sell if you want to hang this over the dinner table. [via Gizmodo ] A touch of copper [Zombie84] built a prototype of a robot arm out of copper pipe.

Let’s face it, walking around in the rain sucks. [Matth3w] is trying to add a little whimsy to an unpleasant experience by adding an LED matrix to his umbrella . The array contains 80 LEDs that are individually addressable. This is a mutiplexed array that relies on a MIC2981 source driver for the eight rows (or rings in this case), with the ten columns handled by the Arduino. The effect is quite nice as you can see in the video after the break. Now that he’s proven this works, you might want to etch your own PCB in order to get rid of the Arduino board and prototyping shield, making it easier to waterproof the control circuitry. This would make a nice addition to your illuminated umbrella stock . [youtube=http://www.youtube.com/watch?v=Bn3_SrWwsiM]

The juicy details that are as much of a fix as the caffeine in the coffee are missing from his posts. But the hacks are solid. Magicians are hackers. If you could go out and buy the props, the concept are unlikely to impress anyone. [Mario] demonstrates his Nickel Box and a Jedi Mind Trick he built. The Nickel Box is a mechanical contraption that somehow transports a coin from one part of a cigar box to a tiny little enclosure on top of it. The Jedi Mind Trick uses a microcontroller and an old Star Wars soundtrack cassette tape box to put on a light and sound show while it recovers your chosen card from a shuffled deck. Great demonstrations, but no word on what’s going on inside. [Mario’s] also has a collection of… performance oddities. His talking television takes an audio input and displays a 1950’s-esque oscilloscope effect on an old TV. He’s attempting to stop his heart, or burn the house down, or both with a flyback transformer lightning box . And his drawing automaton , well, you’ll just have to see it. We believe in electrons, not magic (even though some say there are no electrons ). So we want to know how those magic props are built. Like any good magician, [Mario] probably won’t reveal his secrets. If you’ve got the goods this your chance. Write a post detailing your magical prop builds and send them our way .

The folks over at Engadget have posted some pictures of the ExoPC’s insides . With the recent return of the tablet craze (remember xp tablet edition?) we’re seeing tablets everywhere. This one has some promise on the hardware side, sporting a 1.6GHz processor and 2GB of RAM.  Unfortunately we’ve heard using solely a tablet interface with windows7 is somewhat cumbersome even with the built in improvements. We’re not too worried though, a customized appliance style linux interface probably won’t be too far off. The last couple times we mentioned tablet style computing, people have emailed us about the Touchbook . It also seems pretty cool, but seems like switching applications is visibly laggy in the demo video. Then again, a slimmed down interface might reduce some of that drag.

Nothing Earth-shattering here. Just, dare we say it, really cute! The venerable Altoids mint tin has become an icon of the maker culture. Browsing through past articles on Hack a Day, Adafruit or Instructables, you’ll find project after project for which these pocket-sized enclosures provided just the right fit. Eminently practical, affordable, but the aesthetics have occasionally left something to be desired. We recently stumbled upon these nifty gift card holders that resemble miniature versions of current-generation game consoles. They might be the perfect housing for your next microcontroller project… These were acquired from our local GameStop retail store and unfortunately do not appear to be available online. Each will set you back $2.99 — about a buck more than the mints, and without the added benefit of fresh breath. Such is the price of style. The shapes are varied, but all are a bit larger than the traditional Altoids tin, allowing ample space for a battery pack , breadboard or microcontroller setup. As with the mint tins, of course you’ll want to insulate your project from the interior metal surface. A bit of contact paper or even some index cards are usually sufficient. In addition to the Xbox 360 , Wii and Playstation 3 tins depicted here, portable consoles — the PSP and Nintendo DS Lite — are also available in miniature form.

We got some silly questions, and some serious, we asked both and now the PUSH teams have answered. The day has passed, the party is gone , and all that’s left is the final interview. The Light Hack Crew gave us a somewhat shorter response then what we were used to, but it turned out to be just as sweet. >Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us. >How did you and your team get together? Any fun backstory you care to share? LIGHTHACK CREW is a trio of 3 crazy coconuts from Perth, Australia . [Dave] and [Tom] have been friends from way back, and [Sharna] is a friend from way, way back, >Have you and your team worked on any other projects? Cellular related projects? N900 projects? No this is our first one together. >What was your main inspiration for your team’s project? It was [Tom’s] idea for focusing the project of light graffiti, and that made me think of [Sharna] as she is a graffiti stencil artist. > How do you think people will react when you finish/release? People will love it as it is fun to create light graffiti and easy to do, all you need is the hacked N900 and the electronic LED can. >Do you have any future plans with your team? Continued N900 development? Update your current projects? Hopefully continued development of the Light Hack software and bring it to other devices >What do you think of the other winners? well as a skater, long boards mainly, I’m interested in the soldering skaters team, the others are great too, >Questions from our commentators. >What are you thoughts on Arduino? Do you intend to use one in your project? [Tom] is the electronic genius,­ but I’d say he found the Arduino pretty straightforward. >How is working with the N900 hardware and software? Great from the little I have looked at and used, the phone is very powerful, its not running a snapdragon but damn can it multi task! the open source Maemo OS is very cool, the fact that it is linux makes it so much easier to develop for, as so much is setup for it already – SDK installed VM image is the way to go. >What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android? I think its great, I tried the iphone, but objective C was new to me, along with the $100!, haven’t had the time for android yet. But would like to check it out. >(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project? We use 4 AA or 4 AAA batteries at the moment. Im sure we could wire up any sort of battery. The battery life isn’t too bad, as the Bluetooth really only is used when the buttons are pressed, and the LED’s are quite efficient. >Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc) HARDWARE: Bluetooth module, PIC microcontroller SOFTWARE: I used C, for the language, GStreamer framework for capturing the video, and some basic algorithms for image processing: subtraction and a moving average filter for noise removal. >And yes, we actually had a reader (Joe) ask the following (feel free to omit) >How often do you change your underwear? Underwear? Its 38 degrees im just wearing my boardies J Thank you again!

[ "controller", "guitar hero", "max", "midi", "msp" ]
[youtube=http://www.youtube.com/watch?v=azfgasnWtW0] [Robert] wrote a program using Max/MSP that lets him make music with his guitar hero controller . There’s another video after the break where he walks through the various features but here’s the gist of it. This works on Mac and Windows and allows a sort of ‘live play’ or midi mapping mode. In the midi mode each key can be configured to do your bidding. His example uses the pick bar to scroll through different samples and the green button the play them or the red button to stop. The live mode us much more involved. In the software you choose the type of scale and the key you’d like to play in. This makes up for the controller’s lack of enough frets to make it a chromatic instrument and these settings can be adjust from the controller. There is an up-pick offset that makes the upward movement of the pick bar a different note than the downward movement. The motion control can also be used as an input. He demonstrates pitch bending and cutoff using that method. This looks like a lot of fun. He needs to team up with [Joran] to add drums to the mix , forming a much more creative rock band than you can buy in the store. [youtube=http://www.youtube.com/watch?v=-1AnfCwl260]

Battery Holder Reuses Blister Pack

[ "a23", "altoids", "battery", "blister pack", "minty" ]
In need of a portable power supply, [Alastair] threw some batteries into an Altoids tin . The problem was he didn’t have a holder for these size A23 cells. Inspiration struck and he realized the blister pack they came in fits them snuggly and just needs some conductors to complete the circuit. He pulled some battery contacts from a broken CD player. Using foam-based double-stick tape he added some spring to the contacts and came up with a perfectly sized holder that works wonderfully. We’ve tried making battery packs by wrapping the entire thing in clods of duct tape. This looks like it works a lot better and there’s still room to fit the batteries and a switch inside of this minty enclosure .

Propeller Takes Step-a-Sketch To A New Level

[Mpark’s] propeller controlled Etch-a-Sketch is well built and very accurate. He was inspired by the Step-a-Sketch project and he’s carried that design through to a stunning conclusion. The driver board was built around a Parallax Propeller P8X32A microcontroller. But this isn’t just a serial controller board for connecting the hardware to a PC running CNC software. He’s included TV out and a keyboard port so that programming can be done on the chip itself. In the video after the break you can see how precise the plotting is on the Etch-a-Sketch. It is well mounted but also benefits from some software compensation for the toy’s imprecise controls. [Mpark] has also included an erase function that tilts the frame upside-down a few times. This is used not only to erase a drawing but to hide the line created when moving the stylus into its starting position. [youtube=http://www.youtube.com/watch?v=MgyZgqImAHA]

Winners Of The N900 PUSH Showcase Tickets.

Like all great things, they must come to an end. As such, at 10am PST, this morning – our N900 Push competition came to a close. We had some really awesome answers, some really round about, and of course the obligatory – really bad ones. For those that are just on the EDGE of your seat waiting for the final concluding answer to stop the arguing and fighting – to settle this whole dispute. The answer, and the winners are…After the break. Just to recap, the question – You’re working with any one of the team winners in the PUSH N900 competition. Your team needs two like resistors in order to complete the project on time. Luckily your work drawer is overflowing with resistors, and you know that there are only 4 different values since you pulled them yourself from old junk. You close your eyes and reach in. What is the minimum amount of resistors you have to pull out to ensure 2 of the same value? The Correct answer is 5 resistors. [Talin Salway] , [Sari Ibrahim] , [James R. Smoot] , [Jody Halyk] , and [Thomas Remmert] all sent in the correct answer, were picked by us, and gracefully pass their tickets to another winner. In the end [Robrecht Noens] was the only one to respond within our 24 hour limit claiming tickets. Congratulations, and hope you have fun at the N900 PUSH Showcase [Robrecht]! For all those that sadly, did not win. You can still keep up on the party, [Matt] let us know… We’ll be updating our @PUSHN900 Twitter account regularly using the #PUSHN900 hashtag to help follow what you guys are saying. We’ll be uploading video using Qik.com/PUSHN900 Keep checking the PUSH N900 Facebook page for updates as well. And finally an explanation: The entire riddle (as a lot of readers repeated to us in the entries) is based on the Pigeonhole Principle . In the worst case scenario, you reach in and pull out 4 different values. Thus, you must pull out 5 to ensure at least 2 match.

The Mechanical Diode
Mike Szczys
[ "Misc Hacks" ]
[ "diode", "mechanical", "rectifier" ]
A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system. But wait, by connecting two of these devices together he’s built something of a mechanical rectifier. An electrical rectifier converts alternating current to direct current and this mechanical version outputs clockwise rotation no matter what direction of rotation is coming into the device. There’s video which we’ve embedded after the break as well as many pictures on his site but not much explanation. Here’s what we’ve deduced. The two large gears are inputs. Mounted on top of them is a smaller ratcheting gear that will only turn in one direction. This ratcheting gear selects whether the smallest gear on the left or right will rotate, which then feeds the output gear at the top of this image.

Leapfrog Didj: Followup

[ "Claude Schwarz", "Didj", "followup", "gp2x", "woot" ]
Yesterday we mentioned the Woot! sale of the Didj, and we had some comments and emails from readers who had purchased one. We couldn’t resist either, and ordered a couple to take apart and modify. We will probably be following the work laid out by [ Claude Schwarz ], who seems to be one of the leading hackers on the scene. [Claude] has done some work in porting the GP2x libraries to the Didj, which gives a tremendous head start to anyone looking to have a working game system any time soon. There will also be a build log for everyone to follow along at home, and contribute what you want and have, as well as a follow up How-To when a working system is attained. Happy Hacking, everyone.

Update: Adafruit Eagle Library, Now With Arduino

[ "Arduino Hacks", "Tool Hacks" ]
[ "adafruit", "EagleCad", "library", "shield" ]
Adafruit Industries has just added an Arduino shield footprint to their EagleCAD library. If you don’t know, the Arduino headers use non-standard pin spacing . Learn to deal with it, there’s too many Arduino shields in production to have any hope for a change in the future. This footprint should make it a lot easier to design your own boards. If you use this package make sure you’re getting the library from their github, they’ve been adding parts regularly . Setting up version control will make sure you always have the latest libraries. [Thanks pt]
