Can anyone recommend a 24 hour battery solution? 3 days would be even better. Very large LIPO batteries seem to be expensive. I was considering a power dock and USB power bank (the sort that charges phones). Will the power dock light up the indicator LEDs if I do this, burning power? Is there anything else on the power dock that will consume power?
I also need 5V for a sensor.
Any other solutions? I am still trying to decide whether to do this design as my first Omega2 project, or do it with AVR which will take a lot longer, but I could do a really low power AVR solution.
