Cooper Wiring Devices TR7735W-BOX night light teardown
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.
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.
