Nixie Tube Tachometer – Arduino & Megajolt Spockie-Tech writes –

My Arduino powered, Megajolt-driven Nixie Tachometer ! More Information here – This is a prototype I made to test several technologies I am developing for my other Project (a 1976 Valiant Hemi Charger). Most of the details are in the Video. Arduino (AdaFruit Boarduino), I2C Bus powering the OLED Display and Tayloredge Smart-Nixie Sockets running In-1(4) Nixie Tubes, In-13 Nixie Bargraph, Megajolt Distributorless Ignition Controller controlling the ignition timing and feeding the RPM (and other data) to the controller. Source code and Construction Tips (but no drawn circuit diagrams yet) are available if you contact me on the MegaJolt (www.autosportlabs.org) Forums. No, I won’t build one for you (unless you are prepared to pay consulting engineer hourly rates), but I will describe and help you build your own. Yes, I know the Gemini is hardly an impressive Street Machine, but its my daily driver parts-getter that I’m testing this stuff on while I build my Triple-Webered Hemi Charger where the final version is intended for. :)

  1. Awesome! I’ve wanted to do a Nixie car output of some sort, but had only thought of speed. Tach is a really good idea!
