power consumption on power down mode
What is the power consumption of the squarewear?
Specifically, if you put the atmega in power down mode (turn off all features, including adc, etc), how much power does it draw?
I would like to estimate what kind of battery life I can expect for the squarewear if used for data logging applications. I would put the atmega in power down mode, and wake up every 8 seconds using the watchdog timer, take some measurements and write on eeprom, and go back to sleep.
A smaller version for wristband form factor
I love this project, but it is still a bit too big for my project. Would there be any possibility of a micro square for use in wristbands?

Tried plugging into USB 3 ports, USB 2 hubs connected to USB 3 port
I'm on a Thinkpad x230 if that's of any help.
Let me know if I can help with debugging
Cheers
