Raspberry Pi’s answer to the iMac
If you always wanted a sweet looking all-in-one computer like an iMac, but without OSX this one’s for you. [Michael Davis] glued everything you need for a Raspberry Pi computer to the back of an LCD monitor.
Dancing Japanese robot shows high creepiness factor
You’ve just got to see this one to believe it. Someone choreographed some seriously lifelike dance moves for this robot. [Thanks – via Dr. GIY’s blog]
Helper script to install MSPGCC
The repositories available to Ubuntu are nice, but if you want to get the newest version of the GCC toolchain for MSP430 microcontrollers you’re going to need to do the compilation yourself. [Jose] is trying to make the process a bit easier with this helper script which download and installs MSPGCC Uniarch.
Easy reset for WRT-54G routers
The whole point of the router reset button being hard to press is so you don’t hit it by accident. But the difficulty of getting to it drove [Noah] crazy so he added his own easy to reach replacement.
Camera stabilization tips
This is a public service to amateur videographers. You don’t need expensive equipment to make a video without nausea inducing shakes. Try out these simple camera stabilization tips. You can use a tripod as a counterweight, or a piece of 2×4 to give the point-and-shoot a dual grip.
[Kevin Harrington] throws a curve ball with this skeleton in a coffin. Instead of going for the cheap scare, he conjures memories of old cartoons when the bony figure puts on a song and dance. When activated it leans forward to hang out of the coffin donning a tattered tuxedo and top hat. You can hear the servos working as they give jerky yet realistic motion to the tune “Hello! Ma Baby” in the true Michigan J. Frog style. Classic!
He figures it took about $36 in parts to put the skeleton together plus the DyIO module to control it from a PC. Four servos are used in total, connected to the skeleton with some steel cable. Connecting it via a computer makes it a bit easier to synchronize music with motion than just using a microcontroller capable of playing back audio would have been. Code is available from the site linked at the top, and a demo video is embedded after the break.
This would also have been possible by using an Arduino as a DMX controller.

[Ruyck] sent us this video of his mini Keepon robot. For those who haven’t been initiated, Keepon is a very emotive, and extremely expensive, dancing robot. He is deceptively simple looking, but as you can see in [Ruyck]’s version, it is fairly complex. [Ruyck] has used a mini RC collective pitch helicopter assembly for the motion, which makes controlling it fairly intuitive. At first, we were not too impressed with [Ruyck]’s final implementation, which you can see along with a comparison video of Keepon after the break. Then we realized, all he as to do is find a way to attach the bottom of the foam body to the base to achieve much more of the squash and stretch motion of keepon. A little creative programming and this little fellow could be made autonomous and synchronized to music.

With concerns about the environment at an all-time high, do we roll up our sleeves and fix the situation or set our fears aside and dance the night away? [Andrew Charalambous], a nightclub owner in from Britain, doesn’t think we should have to choose, so he installed a dance floor that harnesses power from dancers into one of his clubs.
The dance floor uses piezoelectrics to collect the power: as clubgoers dance, electricity-producing crystals under the floor are compressed, producing a small current. The current is collect by embedded batteries, which in turn provide the power to lights, audio systems, and other parts of the club that consume electricity.
It’s certainly an interesting idea, but we’d like to know just how much power these floors are able to generate. Is this a gimmick or a genuinely practical solution? [Charalambous]’s club has adopted the somewhat hokey policy of forcing patrons to sign a pledge to be climate-conscious and do what they can to help the Earth, but that’s a small price to pay to earn green karma and have fun at the same time.
