The Arachnio Due is finally coming together. The biggest boost I've received over the past few months is from Thibault Viard, who is currently porting the Arduino core to work with the Atmel SAM4S series, which gives me access to a much better processor. You can check out his code here: https://github.com/aethaniel/ExperimentalCore-sam

I've been working more on porting the Arduino WiFi library to work with the AT command mode of the ESP8266. I tossed out my earlier attempts and restarted it as a driver-level re-write. I've implemented everything but UDP, but I haven't tested much of it yet. You can check it out here: https://github.com/logos-electromechanical/WiFiESP

I am hoping to unveil it publicly as the Seattle Mini MakerFaire in September, and go live on Kickstarter soon after.
