Another crappy 'how to' video. This time, it's how to build the Lost Model Beacon.
Arduino sketch is available from here:
You'll need the following:
Arduino Pro Mini 3.3v
Arduino data transmitter
433mhz Antenna
1s (3.7v) lipo or similar
Baofeng UV-5R for receiving the beacon signal
You can use an Arduino Pro Mini 5v and a UBEC with power from your main flight battery but I don't recommend it - If your flight battery gets ejected in a crash, you'll lose your tracking ability!
