Intervalometer #3

In preparation for the next meteor shower, the 3rd intervalometer was built. Using lessons learned from the last 2, it's supposed to be bulletproof & function in any environment. Dip switch programming is back. That was always guaranteed to work.

Wireless is gone. That was a train wreck. It would have to be done by a really reliable radio on another board, but the last one was so complicated & clumsy to set up, it never got used.

A coin cell would be nice, but the 350mAh LiPo was available. It should last for the next 30 years.
