How old-school do you want to get here?

Electronics as a hobby covers everything from tinkering with a homemade radio, to fixing up household appliances like broken lamps and kettles, to assembling a DIY computer.

Before you grab your soldering iron and start taking your TV to pieces, however, please make sure you are safe and are not in danger of electrocuting yourself...
