[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.
[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. Read the rest of this entry »
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.
