Foofy Weensy - Teensy + ESP8266

Built a new one with SD card and it works!

ESP is reading the SD card nicely.

New board seems to be bug free. Party time.

Now the question is, should I attach the Teensy Side to the SD card and thus the ESP8266 via SPI as well. This may mean I will have to change to a 6 layer board.

Next task. Indigogo project, lets see what the maker community make of this, see If I can sell 1000 units. Current price looks around $39 (NZD) so $26USD at current exchange rate.

New and improved (aka bug fixed) PCB's have arrive. That was really fast turn around. Thanks pcbzone.

The PCB Trace antenna now works like a charm. Now need to test the SD card attached to the ESP8266 and see if it can serve up some webpages.

Time to rule the world :)

Moved from Description was in the wrong place (Doh!)

Currently tuning the Wifi Antenna. My First PCB Trace Antenna was incorrect as I mis calculated the Feed Trace Width and Antenna length. But the Ceramic antenna saved the day.

Time to search for someone with a Network Analyser or Spectrum Analyser that won't charge the Earth to use it, or find some Low Cost 2.4Ghz add on for my Oscilloscope.

I've fixed a few bugs and rerouted some of the lines from the Ground plane to the data layer (Yes I know, bad form putting traces in the ground plane, but I just can't seem to find a route without using this plane).

I've added a Micro SD card socket as there's room for one, and hooked it up to the ESP8266, ideal for serving Webpages and images.

Ordered a new board and stencil from the Manufacturer. Let's hope everything is now correct.
