I know, my question is not really related to biohacking things, but you all are always so helpful and kind, so I simply hope you can help me with my project:
Basically I try to find a solution for locating lost arrows (archery). I thought about infrared leds with an infrared camera (or simply a camera without IR filter), I thought about a similar solution with UV, and came along to RFID (since I found an RFID locator for golf balls).
The issue is the physics of an arrow: Thin, carbon or aluminium, and weight and balance is definetely an issue.
A glass tube would fit great. But with passive RFID I won’t get results out of a range of some inches.
The target is to find arrows at least in 10 meter (30 ft) radius, so here are my questions:
Do you know any tube-like active rfid-transponders with a very small and light battery? Or any other form factor which could fit into the inner space of an arrow? And do you know any device to track them? Measuring the field strength could be enough to find the arrows…
Or any other ideas?
Thank you all for your input!
