I design a hit counter for smbaker.com using a Nixie Tube display module and a parallax propeller microcontroller.

Scott’s iPad digital audio optical receiver / amplifier
Unhappy with existing receiver options, I decided to build my own digital-audio receiver. I used IN-13 nixie bar graphs, a MiniDSP/MiniAmp stack, and an airport express. I even added an Alps MotorPot controller by a parallax propeller microcontroller so the volume can be changed from a web browser. Eventually modified this project to play Pandora using a raspberry pi.
Read MoreInterfacing Dekatron Tubes to a Microcontroller
Everything you ever wanted to know about interfacing an old soviet dekatron tube to a microcontroller. I use a parallax propeller and some MPSA42 transistors.
Read MoreThe Packetron 9000
My favorite dekatron project. Using a parallax propeller to query my cisco router, I visualize my Internet throughput using old Russian dekatron tubes.
Read MoreAuto-dimming Chumby hack
While my chumby has long since died, this page describes my efforts to modify it to add automatic dimming, because the thing was just too damn bright at night.
Read MoreHigh 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?
