This might be one of the Steampunkiest of Instructables projects, where even the schematics have a vintage flair! Shared by Junophor on Instructables:
After building the UV-Fluorescence-Steampunk-Lamp I experienced -while I presented this apparatus at the maker faire Ruhr, Dortmund 2017, that nearly everyone switched on the lamp, took some photos an went away without switching off. So the High Powered UV-LED´s started to heat up and that´s not good. So I needed to create this Steampunk Punch Clock as a time-switch . And at least „I did it my way“ ;-))
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
