Brush Up on Your Trade Craft With This Tiny FM Bug
1 min read
Summary
This one-transistor FM transmitter builds on previous work and could prove a useful addition to the toolkit of any would-be spy or teen doing their best QAR firmware.
As the article and linked video show, it is not a huge challenge to build and most of the parts are easy to source.
The biggest challenges are keeping it stable and getting the frequency range right, but some clever work with a zener diode helps solve this issue.
The design could also be useful in other applications such as wireless temperature sensors or other data transmitters and could be a great way to get kids into hardware and open source electronics.
