Some people claim cd’s brought about the death of the vinyl record. Some people try and prolong the life of their precious wax by supporting it through thick and thin. And some people come up with home made, steam powered turntables.
They really shouldn’t have.

Übermaker Simon Jansen of Auckland, New Zealand, wrote in to share his Arduino-controlled, steampunk (literally!) turntable.
This is my steam powered record player built to play a Sex Pistols LP. Yes, it is true steampunk. The engine was made mainly from bits and pieces I had lying about in my junk box. The boiler was made from some copper water pipe and a bespoke platter and base was made using wood. I am using an Arduino to control everything buy using a coil to detect the passing of magnets in the edge of the platter. The Arduino works out the revs then feeds this information into a PID controller the output of which drives a servo controlling a throttle on the engine. The speed is regulated to 33 1/3 (well, more or less) and displayed on an analogue meter. The tone arm uses an old phono cartridge that connects to my phono pre-amp and into my stereo. The hardware is complete and works well but the software could use a little tweaking. It does however run!
