This is fairly accurate, although there are still some unknowns as described in the notes.

NOTES:
- Assumes transmitter PCB and main PCB on same board
- We can probably use some flash PICS that I already own for the transmitters so the cost could be 0
    (since I can have them back afterwards)
- The price for the gadget is likely to go up as we add stuff and if we add an expensive case and PCB
