How Make A Wooden Fm Transmitter - Circuit Fm Transmitter Mount Unusual - A Piece Of Wood With Nails - No Pcb And Solder

FM Transmitter Circuit Boardless Assembly

FM Transmitter Circuit Boardless Assembly In this video, we are showing you how to make a FM transmitter Bug using 2 transistors and a wood circuit board.

The reason for author make FM transmitter this from wood is because  people that can not make there own circuit boards ,can not solder or can not find the capacitor trimmer for adjusting the frequency, well good news this FM transmitter can do without all that ! so i made the circuit board from nails and wood!

This FM transmitter Bug is very easy to build.

Parts used:
Homemade wood circuit board.
2N3904 transistors x 2
1nf ceramic capacitor
100nf ceramic capacitor
