This site gives many ideas eventually.
Seeing the construction of a lamp from parts of a Porsche 911 I decided to build myself a piston lamp from old parts I found. So an old dynamo, a distributor, a useless piston, 2 spark plugs and one fork from gearbox with a 220 to 12 volt transformer synthesis mine lamp for my small office. Hope you like it.
This is the first step. When you find some other parts like a tachometer that will turn it into a clock or an instrument reading of volts will include it.
