A bunch of stuff from eBay turned up at last. I probably won't have to buy a coloured SIL header ever again. More ESP8266s. Some teeny tiny PIR modules which only have a 10mm dia. Some soil moisture sensors and some USB to ttl serial converters.

Having some fun with some PIRs for lighting. I'm using CAT-5 flex. The sensors are daisy chained allowing for six sensors per run.
