FM Transmitter Circuit Boardless Assembly

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 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.

  1. HI TONI

    very interesting this remind me my early day in electronics
    when i did not have any tools like solder and other things
    thanks any way
    beh

  2. Caro Toni, grande abraço irmãozinho!
    Passei uns tempos afastado, mas aqui estou de volta! Quero apresentar uma ideia que já pode até ser manjada, mas ainda não encontrei um artigo sequer sobre isso. Trata-se de um transmissor de FM monofônico feito a partir de um velho rádio com etapa osciladora de RF a transistores. Funciona muito bem com receptores à válvulas se o experimentador introduzir uma bobina feita na ponta de um fio rígído (22 AWG) próximo ao circuito oscilador, mas a ponta do fio mais curta deve ser ligada ao chasis. Todos nós sabemos Toni que um rádio qualquer ligado na mesma faixa que outro, a alguns centímetros de distância gera uma portadora nesse outro. Há muito tempo eu experimentei amplificar essa portadora e logo em seguida a modulei com o som de um Walk-man e funcionou. Se o sinal for multiplexado, temos então um transmissor de FM estéreo. Espero que a DICA seja válida!
    Até mais!
