Been a while since I last wrote a log... I've successfully ported the code from Arduino 101 to ESP8266 and ATMega32u4 bases. I'm using Adafruit feathers for the prototypes. These are great boards for prototyping:

• They have feathers/wing for multiple chip types and functions  (I've played with the ESP8266, ATMega and M0 Cortex models, with "add ons" for RFM69 packets and TFT screens)
• VCC is 3.3 V - this restricts some sensors (namely gas sensors). I'm ok with the trade off, as it reduces battery consumption.
• There's a wealth of documentation available.

It hasn't been perfect, there are some challenges - specifically, I struggled to get the RFM and TFT components to work together (though this isn't because of the Adafruit construction - it's due to the way the RFM libraries are written).

I've also started to design and print the cases for the components (building on the files provided by Adafruit).
