The clockface is enameled, the clockwork consists mainly of brass made gears and some springs made of steel. Some clocks had too much damages, but one clock was working best after a careful cleaning. In a dark corner stood an old wooden box with some of these very old punch clock timers used around 1920/1930 in former photo-laboratories- They were started by activating a giant solenoid, Everything was thickly covered with dust. Two years ago I got the chance to discover a steampunk treasure when I helped to clear up an old mechanical workshop which already had been closed for more than five decades. Now let me show you first a small „movie“ about this switch workingĪnd here comes the instructable explained in its well known detailed way! This punch-clock-switch will be supplied with an external DC-plug (5,0 Volts, 2A) for normal use at exhibitions or you can test its light functions with three AA-batteries (4,5 Volt) which are integrated in this object. Additional, the clockwork is illuminated by three amber colored LED and one signal light which consists of an uranium glass marble and a „blacklight“ UV-LED (405 nm) shines too (see also Steampunked Magic-Uranium-Light). While the clockwork is running, a connector closes a wire gap and opens when time is over. Just push down down the plunger which starts the mechanic of the adjustable clockwork. So I needed to create this Steampunk Punch Clock as a time-switch. So the High Powered UV-LED´s started to heat up and that´s not good. 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.
