WORKSHOPS
I've been making things out of discarded electronics stuff and general scrap materials for over forty years. In some ways, modern junk is less adaptable than the old stuff was but there's more of it being thrown away than there ever has been and the quality of some bits like miniature stepper motors is amazing. Children's pedal generators and hub disc twirly things are actually fairly easy to make once you realise you can do it.
To help other people get started, I can facilitate workshops on recycling electronics including dismantling things like old computer printers and faxes with guidance on which parts are useful and interesting, or making LED windmills or other small generating devices from pre prepared kits. At festivals and other outdoor Green events, we use solar power for the soldering iron and occasional power drill. Everything else is done with hand tools.
The best aspect of stepper motors is that they can't produce enough electricity to burn out wires or cause an electric shock, but they will immediately produce enough power to light LED's when spun with fingers.
