Energy harvesting board
Found an energy harvesting board that I designed ages ago in my drawer. Never ceases to amaze me how this works, made a video of it working off a peltier element and a t delta of 10 degrees C. Thinking of creating harvestduinoRF? #WearableTech #IoT

Noname esp8285 smart plug
Fiddling with noname #esp8285 (not esp8266!) smart plug. Build quality is better than Sonoff S20, relay rated 16A. Difficult to reflash though as no header with TX/RX is exposed
