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.

I’ve been super busy lately, working on a new installation. I’m excited to document the process more at some point, but for now I have some videos to share with new LED effects I’ve been working on:
Some of this work has been in Blender or Maya, and he’s been working on plugins for those 3D modeling packages to generate scene and animation files for HQZ. These scripts are now available in the HQZ Github.
Micah Elizabeth Scott (@scanlime) came to talk about Fadecandy, a really neat way to control smart LEDs (NeoPixel, AdaFruit’s term for the WS2812). The conversation ranged from beautiful LED control algorithms and open source embedded projects to triangle tessellations, art, and identity.
This week, nemik posted a package for OpenWRT that makes it really easy to run the Fadecandy server on a cheap battery-powered WiFi router, the TP-LINK TL-MR3040. I just got my MR3040 in the mail, and I recorded a quick video demo:
I recently discovered Micah’s awesome Fadecandy USB controller for WS281x LED pixels. One of the things that I like the most about it is its “fcserver” to control LED pixels using Websockets. That is fantastic, but all implementations I’ve seen have people running it on a RaspberryPi or regular PC.
I wanted to create a sort of “stand-alone” and embedded version of this using less expensive TP-Link routers, running OpenWRT. My current favourite of these is the TP-LINK TL-MR3040 but it would work just as well with the infamous WR703n or others; so long as they have USB support.
