@Kevin Walseth at Digi-Key has gotten us all the electronic components that we need.
But we also need:
- Watch bands (probably 22mm NATO)
- Mechanical parts to assemble the top and bottom board (a sandwich with the battery in the middle)
I ordered this from Amazon for Michael:
It is a 4 pack of 22mm NATO bands for $13.99. That is $3.50 each. This seems not be a good value. We need to source 300.
@Michael Welling found these 7mm standoffs on Amazon but quite expensive
That is 1,000 pieces for $160. $0.16 each. We need 4x 300 so 1,200.
Also, we not certain what standoff is best. We are making a "sandwich" with top PCB, LiPo battery and bottom PCB:
