have you tried using a Adafruit PowerBoost 500c or 1000c for power? i think it could be useful in this aplication cause it can take a 3.7 lipo/li ion battery and it has LEDs for charging, power, and lowbattery.

i used to have the same power setup (not teh same but close components) but it was too big for my application. maybe with this advice you could make ti more compact and more portable. TNAKS FOR LISTNING!!

Glad I could help.

Thanks for the heads up :)

can you add a URL to link from Instructables to the video (I can't seem to find one)? this is the first time I've seen someone building the same thing I had an idea for, and I would really like to build this.
