Thanks for the post. What problem domain are you really attempting to
solve ? The photo, cute bird by the way and thanks for naming it,
indicates your feeder is well within reach of a power cord. A Pi plus a UPS
solves your power issues, costs next to nothing, and takes no time to
The imp looks pretty interesting, Thx for the link.
Now a remote setup does have all of the power issues you mention. That
situation begs the question of "how remote" ? Too far for WiFi, etc...
IMHO, these are all great questions. There's nothing wrong spending time
and money on these real-world puzzles. Much better than watching TV (again
IMHO). Enjoy the journey!
I am interested in low-power sensor networks. Also, I would consider
reflowing some Electric Imp modules on a custom PCB board if people are
