A temperature and humidity probe for the Elk M1 Gold
I design and build a temperature and humidity probe for the Elk M1 Gold Alarm / Home automation panel. A parallax propeller microcontroller and an SHT11 sensor is used.

A futile attempt to tear apart an LED night light in order to alter the sensitivity of the photocell.
Read MorePropeller-powered IN-12 Nixie Clock
My first self-designed Nixie Tube clock prototype. I use IN-12 Nixie tubes along with a parallax propeller microcontroller and a UP501 GPS module.
Read MoreNixie Tube Web Counter
I design a hit counter for smbaker.com using a Nixie Tube display module and a parallax propeller microcontroller.
Read MoreScott’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.
