Will be more than happy to put a couple of units together for the Toby shoot. How many gongs will you have out on the range?

Cost - I have not done the calculation yet. But this is based on Arduino (cheap as chips), and components off AliExpress (like the enclosure, antenna, etc). The most expensive part is the radio chip ($15) and the 14500 Li-ion battery ($12) and the actual pcb ($15). My aim was to do this for less than $100 per unit, and at this stage I am sure that it is coming in way under that. I have also already built in a Solar Charging circuit, but I have not tested it yet - I do not think you want to run around replacing batteries all the time. Will keep you posted.
