Favorite way to power Moteinos?

set up a counter, then every time you wake up from those 8 sleepy seconds, check the counter and go back to sleep ASAP. Ie if you want to wakeup every 32 seconds just sleep 4 times. If you need some exotic sleep time like 17 seconds, then use the narcoleptic library, it has the same functionality and has some functions to divide your given sleep time into chunks that will approximate it as closely as possible (watchdog can only sleep in fixed amounts of time, going from a few ms to a few sec):

You got an FTDI Adapter from my shop and it's not working? That would be a very low possibility.
How exactly are you using it, what steps are you taking? (Software wise...)
What is the target board you are choosing?

Using the Arduino IDE. I didn't put a whole lot of thought into it, I just wanted to perform a quick test. I stopped once I couldn't get the COM port to come up in the IDE.
