Belt?

V1.5 limit to just 8 motors for simplification purposes.

For a belt mod, reserve some V1.0 boards and instruct people to add diodes - deals with inventory problem.

NP V1.5

• Settle on new parts

New parts for LiPo battery upgrade mod:

battery: sparkfun PRT-00341 charging IC: newark 59J2761 USB Mini B jack: digikey 670-1190-1-ND JST jack: digikey 455-1719-ND

• Mounting acrylic - how many screws?
  • Make a mock-up
  • Border pieces - later cut tongue and grooves for snappage
    • Ask Rachel for feasability
  • Hold the boards in with notches (+$20 for more than 6pts board shape) = no holes!
• No atmel socket - it's tall enough and people can figure that out
• Investigated brownout detection, not useful

TODO / INVESTIGATE

• Bigger cap to make the voltage drop less meaning the atmega won't reset when motors ramp up on low batteries
• Switch to internal oscilator for simplicity and power saving, timing vars need retweaking???
• Find/make through-hole usb mini eagle part

• Add copyright info to code and old eagle files
• Batt charging cap not spec'd yet, just copied the 0.1uF part
• Put in RGB LED red=charging green=on
