DIY - Tiny FM Spy Bug for Under $20.

from the creator...
"I wanted to know how small a FM spy bug could be build when manually assembled.

This is what I came up with, it measures about 0.05 square inches and is powered by a single 1.55V silver oxide battery.

Frankly, this is just a fun object, I don`t have a practical use for it.

I`m sure professionally made spy bugs could even be smaller and work at higher frequencies which allows the antenna to be made smaller." more

The complete instructions and Gerber files (for PCB manufacturing) for this FM spy bug are available on Gumroad and Payhip:
