  • Wondering: would this also work with a low-voltage TEG and a battery charger? http://www.tegmart.com/thermoelectric-generator-modules/tegpro-thermoelectric-generator-module-1-watt-2-vdc-low-temp/

  • Yeah, two months of (sporadic) work later and it doesn't look easily possible. It would take some doing, but could be achieved with the TinyWireM library + some mods on the Sparkfun lib.

  • Can someone confirm that FM frequency is set as a three-digit integer (ie 99.5FM would be 995)? In the Hookup Guide it shows channels like 996, or is that for non-US radio frequencies?

  • The SLP function puts the motor to sleep – how do I "pull it low" from my Arduino? I'm guessing that means connect to ground, right?

  • Thanks M-Short! I've compiled lots of things for ATtiny chips in the past, but I think the interrupts etc are different. The library wouldn't compile for me for ATtiny, but not because of memory I don't think.

  • My embedded programming is pretty bad – would it be possible to adapt the library for an ATtiny 85?

  • No code on the Github link! Not sure if they used to have some and it was deleted? Would be great if Sparkfun put together a tutorial on controlling this arm via code.

  • I miss the red box-wall... :(

  • Which direction do these go in the Eagle library? Is the front the end with the little circle or the long rectangle?

  • Looking through the documents above and the comments below, I'm not entirely sure how to use the sleep functionality of the board:
    1. Do I simply use another digital pin and set it HIGH to sleep and LOW to wake the board up again?
    2. What does this accomplish? Does it mean I won't be pulling energy from my power supply (or significantly less) when asleep?

No public wish lists :(
