A project log for TinyBot: Robot Family Development Board

Shlonkin's wonderful tiny robots get their own PCB and on board battery charging.

Finally found (on ebay, of all places) a source for cheaper rechargeable lithium ion 2450 size batteries.  At 95 cents each, that is less than 1/2 the cost of prior source:, and brings the project cost below the sacred threshold of $10 per tinybot (not including the cost of component shipping from Mouser, although even then the cost would only be a hair more than $10 if you build 10 at a time).
