Furniture hacker Boris converted an IKEA Sniglar baby changing table into a portable folding lightbox. [via IKEAHacker]

I first thought to keep the table structure as it, but finally, I preferred to use the two level of the table to make one foldable table. I first fixed together the two vat with a long piano hinge. Then I stuck aluminium foil into the vats to reflect the light and I fixed four neon tubes into it. A few meters of cable later, I then closed the vats with two white and opaque plexiglass panels and that's it.

Here's a Design News Gadget Freak column on using an ARM-powered processor (the MBED ARM Cortex-M3 MCU Dev Board) to make a Billy Bass animatronic fish speak and move as you wish. [Caution: mild cursing in the video.]

Gadget Freak Case #150: Hotrod Your Billy Bass

Maker Aki Mimoto wrote in to let us know about his exciting new Arduino/VR/Web app mashup. He's wired up his wife's bike on a stationary platform to an Arduino using a reed sensor. Using the sensor data from the bike, along with data from a head mounted display (HMD), Ari is able to accurately pinpoint his position within Google Street View. Additional data from the HMD allows Ari to look around at his surroundings for a true VR experience.

Pragmatically explained, it means that I don't have to sit in the darkness or stare at my garage door while I'm huffing away. Hopefully once this is done, I'll be able to spend a few nights a week pedalling away downstairs and work my way across the US or Australia over the course of the year.

This has to be the coolest car mount for any mobile device out there. Originally designed for home use, maker remington870_20ga from the everythingpre.com forums wired a stock Palm Touchstone Charging Dock to run directly off his car battery using off-the-shelf components. Not only do you get an unencumbered view of the screen, your mobile device gets a chance to charge itself without all the messy cables.

MirlitronOne explains how to turn a Velleman MK107 LED Running Light kit into a simple 8-step sequencer for use with analog synthesizers. A handy kit hack, but it's also not too much work to build one from scratch.

John Boiles, who earlier this year showed us how to control an RC car using an iPod's internal accelerometer (and also how to control the lights on a dance floor in more or less the same way), is a member of Austin, TX, based engineering collective Waterloo Labs, who have up-gunned his iPod technology to control steering, brakes, and acceleration on a full-size automobile. Definitely not the safest hack I've ever blogged, but probably the most impressive. Great work, lady and gents. [Thanks, John!]

Humberto writes in to point us at this handy use of the Google Voice transcription feature. In his Voice2LED Project, Josh converted a simple LED sign into a voice-activated one by connecting it up to his phone number. It turns out that when you leave a message on a Google Voice voice-mail account, it is automatically transcribed into text and sent to your email. To take advantage of this, Josh built a program that looks for messages that start with a particular phrase, and then displays the rest of the text on the screen. He built the sign using instructions from nerdkits, and his source code is listed on his site.

This looks like a fun way to leave messages or notifications to the people that you live with.

The nice thing about IKEA furniture is that it is cheap and easy to hack. In other words, lets say that you were to buy two cheap $30 Gorm shelving units and assembled them to discover them that one was crooked. Well then, it would be really easy to spend an afternoon converting the crooked one into a solid, stylish and symmetric bookshelf bench. As you probably just guessed, this Instructable will show you how to convert a Gorm shelving unit into a bookshelf bench. With a few extra peices of hardware and a couple of basic power tools, you could be on your way to relaxation and organization all at the same time.

MAKE subscriber Justin fused the convenience of digital music with the feel and playback functionality of a cassette -

It is a cassette tape adapter and a micro usb port hooked up to a tiny mp3 player that I picked up at target. Its a simple build and only took an evening. Its an on going project I started a while back.

Want to rock out, but forget to bring your instrument? Then you might want to check out Instrumentube, a collection of YouTube-based instruments that you play by dragging the video time slider to match up to the correct note. I can't imagine this being a very efficient way to play music, but it is a pretty funny hack.

[Thanks, Jacob!]

Master iPhone unlocker George Hotz aka GeoHot has done it again. Apparently the current iPhone 3G/3GS baseband has been successfully cracked and new unlock code titled blacksn0w will soon become available through the blackr1n jailbreak. [via iPhoneSchool]

Have a broken robotic toy that you want to bring back from the dead? Why not follow the lead of Morten Skogly, and re-animate it with a toy synthesizer? The FrankenDog looks like a good way to get some use out of an old toy, at least until you get around to pulling the motors out of it. I like the control 'switches' built by sticking conductive tape at the edge of the plastic piano keys.

RFID card readers becoming passé? Maybe what you need to guard the door to your high-tech lair is a secret knock detecting door lock. Using an Arduino and a bunch of parts found around the lab, Steve Hoefer built a device that unlocks your door when it receives a certain knock pattern. It works by counting the time between successive knocks, and can be re-programmed at the touch of a button.

Of course, this system is susceptible to a replay attack, because anyone can listen to the knock pattern and then know how to get in. If you are planning to use something like this, I would recommend either incorporating a timestamp into the message, or using a series of one time knocks, in order to make it harder to break into. Actually, that might make it more secure than a regular lock.

From Instructables user Eric Kingston comes this Arduino-controlled Silly String shooting pumpkin. It's motion-activated, makes a Goblin-esque cackling noise, and Tweets a report each time it squirts another victim.

Check out this cool Android-based head mounted display. Andrew Lim of recombu.com used an HTC Magic running Google Street View, safety goggles, and some cardboard to fashion one of the coolest HMD this side of Lawnmowerman. [Thanks, Andrew!]

Have some extra soda cans laying around the lab, that are taking up too much space? Instead of just smashing them with your boot, why not build an electromagnetic crushing machine to implode them, using a high voltage source and some large capacitors? That's exactly what Bob Davis has been doing with his can crushers.

Actually, I can think of a lot of reasons why one wouldn't want to do this, especially the big safety one. It looks cool though, and slightly less complicated than the coin shrinker. [via hacked gadgets]

Here's another awesome project by Vadim Ryazanov of Let's Make Robots. Called Mr. Wake, this robot has the duty of protecting its alarm clock from any bleary-eyed, would-be assailants. Instead of running away after its snooze button has been pressed, like the Clocky, this 'bot engages a homebrew IR sensor as soon as the alarm goes off, and takes off if it detects anything even trying to get near the button.

I love the choice of building materials, especially the frame made of heat-formed plastic pens. Nice work!

Zibri did some investigative hacking with the Force Trainer (brainwave controlled toy) and posted a basic interface schematic using a MAX3233 to interface with his PC via serial. It turns out the EEG headset is sending out data as ASCII characters @ 57600 baud - should make for some quick and easy hacking! Time to add mind control to those microcontroller projects.

MAKE subscriber thom writes in to tell us about Marc Fischer's ambitious project to do something creative every day, for a year, and document it. One of his latest projects is a DIY MIDI footpedal, made from a pocket-sized MIDI keyboard and some blocks of wood. I would not have considered doing this, but it looks like it came out really nice. He doesn't mention it in his write-up, but an interesting side effect of re-purposing the keyboard in this manner is that the foot pedals will be velocity sensitive, opening up some new possibilities for control.

This is just one of his excellent projects, he has also made drone boxes, a music box, a felt monome case, a light speaker, and lots of wonderful photographs.

Back in 2008, I participated in the Thing-A-Day project, which is a similar idea but only lasts for a single month. I nearly drove myself crazy trying to make an electronics/physical computing project every day, but it was definitely a great way to force myself to actually work on things. I would recommend a project like this to anyone who just needs that extra bit of motivation to actually start getting things done. Good luck on finishing the year strong, Marc!

The "tools" section of media artist Karl Klomp's website documents an impressive amount of bent, hacked and homebrew hardware for video manipulation. Devices such as the Failter (seen above)series go through a number of incarnations while Karl experiments with different hardware and uncovers its glitch-ability. The retro-simple feel of the enclosures give give it all a nicely 'scientific' almost medical feel. Be sure to check out his device gallery/ project list for more examples. Thanks to Becky for pointing this one out!

In need of a way to transmit a video signal to an aging antennae-input TV set, John rigged up a working RF modulator from salvaged parts (plus 5V supply) -

I decided not to build my modulator from first principles. A simple design with a UHF cavity oscillator and simple sound and vision carrier and modulation circuits is not impossible to make using parts from a scrap TV set, but when so many set top devices already have a modulator built into them why bother? Instead I lifted the RF modulator from a scrap Salora satellite receiver I picked up at a radio rally.
[…]
To power this modulator I built a simple 5 volt regulator using the ubiquitous 7805 IC. I simply soldered a TO220 heatsink to the module case and built the circuit around it. My choice of capacitor values was based on those I had to hand. I also included an LED to serve as a pilot light to indicate that the unit was turned on.

John Boiles, he of the iPod-controlled RC car, also produced this sweet wirelessly controlled light dimmer, which he demonstrates in this video, controlling different sets of X-mas lights by shaking his iPod. See it work around 1:40, then be sure to check out the dance party at 2:40. The iPod is enclosed in the "law book" prop everyone is shaking around, together with their booties, while they rock out to vintage Bon Jovi, et. al.

More Dorkbot Austin goodness! John Boiles demonstrated this radio-controlled car steered using his iPod's built-in accelerometer via its built-in WiFi transmitter. All you have to do is tilt the iPod, and the car goes. It starts to move around 1:10.

Gordan Savicic and Gottfried Haider of DSbrut fame have tipped us off that they've just released their DS Bluetooth adapter for the Nintendo DS.

Almost two years in the making, we're happy to finally release our DS Bluetooth adapter. The tiny Slot-1 cartridge allows you to hook up the Nintendo DS wirelessly with other devices such as GPS-receivers, robots and so forth. Today we're making all materials of the project openly available, including the schematics and a GPL-licensed software library for the Nintendo DS, because we believe in open hardware design and want to encourage collaboration in the hardware hacking community.

If you've got a homebrew Nintendo DS project that we should know about leave a link in the comments.

Here's a neat idea: using the standard microphone and speakers that are built into most recent laptops, researchers from Northwestern and University of Michigan have developed a sonar system to detect when a user is near the computer. Why is this interesting? Well, the idea is that it can be used to turn your computer screen off as soon as you walk away, rather than waiting the typical 10 or 20 minutes for the screensaver to kick on. It's a pretty neat idea, especially since it doesn't require any extra components, however I wonder how much power the sonar system itself will draw.

Josh Klein developed a machine that trains crows to trade coins for peanuts. Literally, for peanuts. So you fill this thing with peanuts and set it out, say, in a public park, and the crows will scour the ground for loose change, carry it to the machine, and drop it in a slot in exchange for food. The project, dubbed "CrowBox," made a big splash when he unveiled it back in 2007. Now he's made the complete plans for the CrowBox freely available online so you can roll your own. And there's no reason you couldn't train your fly-monkeys-fly to gather other crow-portable objects. Twenty-dollar bills? Keys? iPods? Human eyes? The possibilities are endless. Set one up at the beach! Train seagulls to trade whole wallets for pre-shucked oysters!
