Remove Power Switch

After looking at more details on the Adafruit PowerBoost 500 Charger, I noticed the breakout for the ENable pin. Looks like I don't need the FET power switch after all. The PowerBoost can handle the power switching. Yay!

Add Trinket

I've remove the power switch and added an Adafruit Trinket - 3.3V. That will give the project the smarts it needs.

Bigger LiPo

I increased the size of the LiPo battery from 150 mAh to 500 mAh.
