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. 🙂
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
