The final IoTBox

During the beta testing I have tried and killed many boxes and components to get this far. Hopefully it will save you some time and expense. Note that many items came via China to reduce the unit price.

These articles will show you how to build one.

Background to IoTBox

Back in December 2014, I started to look at a new Wifi chip that had just been released as a means of Internet enabling various Arduino projects that I had been thinking about. I soon realised that this processor (the ESP8266) was actual more powerful than the Arduino and much much cheaper.
