Hi All,
I want to power the Arduino Uno + infrared sensor + Adafruit Wave Shield using solar power. Will this solution do the trick: ?
USB / DC / Solar Lithium Ion/Polymer charger - v2 https://www.adafruit.com/product/390
or do I need anything else (other than the solar panel obviously)
many thanks

Re: Wave shield + Solar charger
You'll probably want a PowerBoost as well:

LiPo cells only charge to about 4.2v at most, and their nominal voltage is about 3.7v. An Arduino can probably run on 3.7v (running at 16MHz from any supply voltage below 4.5v counts as overclocking, which isn't officially supported, but we've never seen a chip that can't do it), but the Wave Shield's output is specifically designed for 5v.
