| May 9, 2021 at 18:24 | comment | added | crossroad | You will have to adapt the circuit design since I was playing around with integrated components. Basically attach a buzzer in parallel to the oscillator power supply with a switch so that when the switch is pressed, it puts the buzzer in circuit. This exploits the fact that a lot of things are VCOs, so changing the supply voltage of the oscillator effectively modulates it. | |

| May 9, 2021 at 18:16 | comment | added | crossroad | I dunno if it works like this, but I made a FM transmitter with an integrated oscillator. Putting an integrated buzzer next to the oscillator changed the supply voltage by a tiny tiny amount, but was sufficient to transmit a morse code type tone. It's not really that practical, could be worth a try if you want something "simple" and fun. | |
