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).Coupon code: "JLCPCBcom" - for all and valid permanently
