Halloween "The Sims" costume with color changing LEDs


This year my girlfriend and I wanted to make a The Sims costume for Halloween. We took a few pics of the build process for anyone else that might be interested in making one.

Hardware Files Now on GitHub

I finally started using Git for my hardware files as well as the software files. You can now find all the schematics and PCB project files for my LED Heart and Digital Clock on my Github page. The files are in Altium Designer format, but I have also included a PDF output and Gerber outputs for the PCB.

Using a PS3 eye toy with OpenCV

I was looking for a USB webcam that I could use for doing some openCV/digital control systems projects. The PS3 Eye seems like a great product for this!
  • $7 on Amazon!!
  • Standard USB interface
  • 640 x 480 resolution. Not great but...
  • 60 fps framerate, up to 120 fps with lower resolution (320x240)
  • Did I mention...$7?!

So I tried this out with a simple program I wrote in OpenCV, and after actually writing a frame-rate counter I realized that I actually wasn't running it at 60fps! Hmmm. Turns out you need to do a little bit of work to get the settings just right.

Waterfall audio visualization

So it's been a while since I've posted. I didn't realize I had not posted my favorite LED visualization so far, a "waterfall" display.

Currently I am still using an ATmega48 to control the LED strip, and a basic FTDI cable to talk to the ATmega. In the future I would like to use a teensy and the ws2812 library in order to control more LEDs.

More to come...
