The FM transmitter circuit itself is based off one of [Art Swan]’s builds, but instead of the solderless breadboard construction you would expect to find in a small demo circuit, [Angelo] went ...

USB Transmitter Circuit Schematic To keep the fm transmitter circuit simple as well as compact, it was decided to use a chip made by Maxim Integrated Products, the MAX2606.

Fig. 2: PCB layout for the voice transmitter Fig. 3: Components layout of the PCB Download PCB and Component Layout PDFs: click here Connect MIC1 and speak into it. The same can be listened to on a ...

[Sean Michael Ragan] built this FM transmitter which shows off its circuitry via a clear plastic dome. The device is electrically identical to one we looked at in September. That version championed… ...

The project is about the size of a standard AA battery which aims to build a single transistor FM transmitter. Having a power supply of 1.5V cell is the main advantage of this circuit. The battery is ...

When the circuit is complete and the components are mounted on the PCB, you can switch on the transmitter. With a radio receiver, you can “hear” the swish on the device, at about 7 MHz.

Here is a very simple telephone broadcaster or transmitter which can be used to eavesdrop on a telephone conversation. The circuit can also be used as a wireless telephone amplifier. One important ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and more.
