This video takes a close look at those little chirping sonar cylinders that might have helped your robot avoid bumping into furniture. They’re sort of like a microphone or a speaker, but looking closer they seem more like a tiny tuning fork with a hat.
I had another video planned, but today the yak stack needed tending after my trusty 10 MHz signal generator started buzzing horribly. Today’s video will be a teardown, repair, and mini-review of the 2007 vintage Protek B8010FD.
Let’s use the glow discharge in a flicker flame bulb to make some weird neon art. This video is a photographic tour and rebuild of a simple glowthing made from a novelty light bulb and an old CCFL backlight inverter. It might have left me with more questions than answers after the laser pointers came out.
I jumped at the opportunity to get hardware in the mail from another like-minded art hacker. In this video I’ll unbox the kit, assemble it delicately, and finally I’ll have to make some squiggles and beeps with it.

Continuing the adventures from Part 1, this video wanders along several tangential paths, trying to get some data out of this device worthy of reversing. This time we spend a bit more time in IDA looking for Z80 code, tinker with SCSI trying to break things, and we even do some necromancy in trying to get grumpydisk working.

This time I find something in my junk drawer with a few teeth marks on it, and it leads to a weirdly specialized CPU built on a super oldschool core.
I take apart a Pyle PDWM1940 wireless microphone receiver, searching for a way to make the output less noisy. Meanwhile, I’ll be using the same receiver for filming.
My friends at Tangible Interaction sent some electronic whiteboard hardware to take apart. In this video I’ll start to look at the transmitters, receivers, and communication protocol.
A quick look back at my partially complete console port of an old DOS game.
