New driver from RepRap, singing

stepper

RepRap has released a new driver board for their stepper motors. They’ve honed the design to be easier to assemble and cheaper. We’re sure all of that is wonderful, but what really got our attention was the video. In the video, which you can see after the break, they run a test file through it to make it “sing” happy birthday. Is this something that everybody does and we’re just now catching on? Why all the musical stepper motors today?

Arduino VGA glitching

For some people, mistakes or glitches has become an art form. We’ve seen it in circuit bending for a while, but the newest version is in video glitching. [Sebastian] has gone so far as to intentionally set up an Arduino to send a glitched signal to a monitor. His description sounds pretty easy. We’re just assuming this is in motion in some way, a video of it in action would be nice.

Power Glove 20th anniversary edition

Using an original Power Glove, a bluetooth module, an Arduino, and an accelerometer, [Biphenyl] brought the system up to date. As you can see in the video after the break, the new version is wireless and much more useful in the games. Skip to 11 minutes in if you just want to see it in action. There’s a full writeup on Instructables if you want to build your own.  We love the power glove and we can’t wait to see a more developed game for it. This beats the Power Glove Wiimote, hands down.

Lego head tracking

[Epoch] Sent in this simple head tracking project using Lego pieces. He’s made a custom mount to hold 3 Lego light sensors on a baseball cap. Then, after modifying his webcam for IR with some floppy disk scraps, he loads up the free-track software and can control his games. For convenience, he has programmed the Lego Nxt to only turn on the lights while he’s holding a contact sensor. You can see it in action after the break. This appears to be very similar to [Johnny Lee's] head tracking. Judging by the video, it’s not as smooth though.

CNC music factory Still Alive

With some careful programming and probably tedious testing, [Tim] was able to get his CNC router to play [Jonathan Coulton's] “Still Alive”. He didn’t just tell the motors to spin at the correct speeds directly though. He computed the 3d vectors necessary to produce the notes. The router thinks it is just doing its job.  We would love to see those vectors rendered out in 3d space. Imagine having a physical sculpture of “Still Alive” as seen by a CNC machine. This reminds us of the Obsolete Technology Band.
