The ESP8266 is an exciting new WIFI device. It's suddenly become so popular because of an influx of cheap (£3) modules been made available on EBAY.
So obviously you have been able to get USB WIFI devices for this price for a while but now they even have all the processing and even some GPIO on board so all you require to access them is a serial port and a few AT commands. This makes WIFI practical for any Arduino/PIC/uC application that has at least one serial port which is a very low bar indeed!
Any way Just seen a YouTube vid of some guys doing some impressive tests of the range of this device which in free line of site was over 400M!!
We had a 3D printer,QSSTV decoding images from our visitor operated "SSTV Selfie Cam" running on a Raspberry Pi and FLDIGI busily decoding data from the attached radio. Around 1000 visitors came through the doors so we had our work cut out demonstrating and showing all things Linux to the Radio crowd!
The meet up was excellent as usual and now extends over 3 days including the Sunday Workshop. Having a single track over two days made it easier to see all the talks with out compromise. Talks varied from designing space capable rockets to flood warning systems and the future of microprocessors .£10 per day with some food represented excellent value!
Thanks again to the organisers for all your work, I for one are looking for Wuthering Bytes £15
