[Lee] wanted an electric Melodeon to use with his band. A Melodeon is a chromatic accordion and there are people who already make electric versions but they are a little too expensive for him. Instead, he bought a toy accordion and added electronics to it. After being thwarted by forgotten PIC skills of yore, he went with an Arduino as the controller. Two pressure sensors are used to detect the … [Read more...]
New Year’s party favor?
December 28, 2009 By 17 Comments
[Infernoz] built a POV display to help ring in the new year. There is a low component count; an ATtiny26, DIP switch, power switch, CR2032 battery and holder, pin header, 8 LEDs, and a pull-up resistor. The board is single sided without any jumpers that we can see. He's moving the display by swinging it on a rope but the PCB is the perfect shape to attach to a fan. We love these blinky displays … [Read more...]
Lightdrawing Robot
December 28, 2009 By 9 Comments
Long exposure "light drawing" photography has become pretty popular lately. We see images pop up all the time that look pretty cool. [Nils] wasn't feeling particularly artistic himself, so he made a robot to do the hard work for him. he can program patterns in, and it will replay them by changing the color of the light on top while it drives around. Though it may lack a little of the fluidity of … [Read more...]
Industrial CNC controller retrofit
December 28, 2009 By 5 Comments
[Jerry] had a beefy CNC lathe whose controller wouldn't respond. He cracked open the case and found a large scorch mark surrounding one of the servo controllers. Rather than just replace the IC and still be stuck with a 23-year-old controller he decided to retrofit the machine with modern controls. The journey from a brick of steel to an incredible machine is fascinating. Using a combination of … [Read more...]

You can try to be unimpressed. You can attempt to feign disinterest. But even the most casual Star Trek fan will get giddy watching this model submarine in action. Apparently there is a group that builds under water R/C vehicles from static models. It's not Star Trek exclusively either, we saw some anime vehicles as well as a modern-day shuttle replica. [via Makezine] … [Read more...]
Five updates for the Steadicam
December 28, 2009 By 9 Comments
[YB2Normal] has updated his steadicam 5 times! For those that remember the original, it allowed indie film makers to create smooth and steady video. Version 2 implemented a new gimbal based on a throttle linkage in cars. Version 3 allowed the user to easily adjust angles and weights to prevent accidentally knocking the assembly. Version 4 seems to have disappeared. And finally, version 5 updates … [Read more...]
XeXLoader reminds us of Xbox glory days
December 28, 2009 By 8 Comments
The newest version of XeXLoader boasts a pretty slick GUI. This is a homebrew loader for the Xbox 360. Don't get your hopes up, it requires an older kernel and you're not getting on Xbox Live if you do this hack. But think back to when the original Xbox was first hacked. Watching the XeXLoader (after the break) sends us back to the days of EvolutionX. Sure there wasn't much that could be done … [Read more...]
