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.

The new circular 7 way WS2812 boards arrived from eBay and they fit perfectly in the top of these solar lights with some small modifications. Click the image to see the other photos.

I came across these cheap solar LED garden lights and immediately knew what I needed to do. They needed to be individually addressable, RGB and controllable from IOT and from an app! =) Probably ESP8266 at this stage with ws2812 LEDs.

Internet Enabled Night Light. I made this out of an old wall wart and an ESP8266 SOC module. Basically took the guts out of the wall wart and replaced them with the contents of a much more modern wall wart (smaller) which left space for the ESP8266 module, the PIR sensor and other bits. The device uses MQTT to communicate trigger events and periodic measurements to a custom cloud service.

• Temperature - DHT11
• Humidity - DHT11
• Brightness - LDR (Light Dependent Resistor)
• Movement - PIR Module (DSN-FIR800)

Had a mate around today for a BBQ and we built some sensors and wrote some code for the ESP8266.
