Electronics on the cheap - electricity for free.
I buy cheap electronics modules and components direct from Chinese sellers via eBay.
Most of this stuff works fine and the gadgets that I build work OK. But some of it is dodgy (even fake) and that's where the fun starts!
I like to use solar panels to power my workshop. This free energy is low voltage, so it's safe (mostly).
