Simple FM Bug – Portable FM Microphone Kit | Short Circuits Vol II Project

Need a small, portable microphone that actually works without an app or a subscription? This Short Circuits Volume II project builds a compact FM transmitter you can clip on, tuck in a pocket, or set by the crib. Works as a baby monitor, a classroom mic, or a simple wireless audio link to a radio. PCB and every part you need is in the box. Solder it up, pop in a 9V battery, tune your FM radio, and you've got a signal. No software, no cloud, no firmware update at 2am
