Hi Dwight,

Are you looking to make these Camping/Emergency lights as a commercial venture or just for your own use?
If it is the latter, you would probably be best served (from a purist aspect) to throw a bit more coin at an LDO voltage regulator.

From my own curiosity standpoint, what have you used for the capacitive touch sensor in your prototype and how do you plan to implement the sensor in your production unit?

Cheers
Barry
