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. 🙂
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

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!
