Wireless headphones transmitter circuit schematic
Jan 3rd
This wireless headphones transmitter assures a quality reception over 2 meters. The oscillator frequency is between 1750KHz and 3500KHz and for antenna we use a ferrite bar. IC1 amplifies the audio signal and TC1 is a buffer. D1 signals that the transmitter is on and is a voltage stabilizer for the oscillator . (more…)

MAX2606 VHF FM Transmitter
Dec 27th
If you want to be independent of the local radio stations for testing VHF receivers, you need a frequency-modulated oscillator that covers the range of 89.5 to 108 MHz — but building such an oscillator using discrete components is not that easy. Maxim now has available a series of five integrated oscillator building blocks in the MAX260x series which cover the frequency range between 45 and 650 MHz. The only other thing you need is a suitable external coil, dimensioned for the midrange frequency. (more…)

Electronic cricket circuit
Dec 15th
Why an electronic cricket? Many people like the cricket sound specially if they live in a big town. This electronic cricket circuit works in pulses, so the battery life is prolonged, the current consumption is just 2mA. The electronic cricket schematic is very simple, it is build with CD4049 or CD4009 wich is CMOS Hex Buffers/Converter. (more…)
Mini FM Transmitter MAX2606
Nov 28th
With MAX2606 we can make a small mono fm transmitter. It is build with MAX2606 and covers at least 20m with 1.5 m long copper wire antenna. You can use this transmitter as an oscillator but change the 1000pF capacitor from the antenna with 15pF. (more…)
