Is it possible to do a small key finder with "long" range (~100m)?
I have a tiny cat and a very big yard with lots of trees. I need to find it when it hides out there. I looked at some XLC-RF-5V but their range is shit.
Most commercial options are too big for my cat or have very small range. I guess it's impossible to get more power on such a small device, but any input is welcome.
Thanks.
