Steampunk Punch Clock
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“ ;-))
