    Have you got a link to the automata that inspired you please? I'd love to see it. Which museum was it?

    Homemade Ginger Beer

    Sounds nice, and easy, but this is not strictly 'real' ginger beer. "Real ginger beer is produced by the ginger beer plant, a creamy jelly-like substance which is a complex mixture of yeasts and bacteria, not a plant."The quote is from here -> https://www.rivercottage.net/recipes/ginger-beerThe plant, if anyone is interested, is available here -> http://www.gingerbeerplant.net/ or from Amazon.

    Stepper Motor Generator

    Sky Ranger - in the circuit diagram the coils on the left are the actual stepper motor. It has two sets of windings (coils) and 4, 5 or 6 wires - com stands for common which is a centre tap on each of the windings and in this example is not being used. Although he shows capacitors in the circuit diagram I cannot see any on the breadboard. Make sure you connect the diodes the right way round the are marked with a line or spot on the negative side. They only allow current to pass in one direction (not the cheesy boy band!) so if you get them wrong the circuit will not work.
