So, just a couple questions before I start buying stuff.
1. Batteries. I'm thinking about using lithium ion cells because they are light weight, and they can recharge many times. What voltage should I be looking for? I was looking at these. Would maybe two sets of three of these be a good setup (two sets for longer life)? I guess the real question would be what have you guys had the most luck with?
2. About this TI PTH08000 (DC-DC converter?). From Harshboy's amazing diagram, I take it that all this does is convert 9V to 3.3V? Is that correct? Where is the best place to find one? Should I start looking at places like mouser.com and digikey.com? Or should I ask someone here for one?
Thanks in advance for any input.
