High voltage power supply
This is the high-voltage power supply that I use to power my dekatron, nixie tube, and geiger counter projects.
Read MorePlasma Speaker
My efforts to construct a plasma speaker, which is basically an electronic arc modulated by a sound source. It all started from an Instructables article I found on the web, and there were several misadventures as I tried to turn it into a workable design.
Read MoreExperimenting with IN-13 bargraph nixie tubes
Why go with some discrete LED bargraph when you can have a continuous Nixie tube bargraph display?
Read MoreProject: Dancebot
My first robot project. I try to reproduce Hanno’s dancebot. It’s a self-balancing robot that uses a parallax propeller microcontroller and some accelerators and gyros to remain upright.
Read MoreUsing the LIS3LV02DQ accelerometer
While working on the dancebot, I had to get this accelerometer chip to work. I mounted the accelerometer to a QFN breakout board, and installed it on a parallax propeller professional breadboard.
Read MoreConway’s game of life on a parallax propeller
One of my first successful propeller projects. I implement Conway’s Game of Life using a propeller and some random eBay LED MAtrix display.
