Beacon Case for TX181 (EV1527) Transmitter and Battery

This was thought to be a proof of concept that you CAN build a beacon which can be worn by larger birds to make it easier tracking them when they wander off. This case is built to fit in a rucksack made for birds and I'm using a stock 3.7V 100mAh Lithium-Ion battery as sodium-ion simply isn't far enough to fit in a small case of 50355mm

Any later Version of my beacon might have a custom PCB in it to make a more fair use of the ISM frequency at 433.920MHz such as 5 seconds of beaconing every 60 seconds and not permanent noise on that freq
