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. 🙂
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
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!
