The piezo effect works both ways: if you apply a voltage the piezo stretches, but also if it stretches it creates a voltage. This principle is used to create a feedback signal which drives the oscillator. The advantage of the self drive is that it will....
Using this circuit, you can measure the actual output power of your amplifier.? You can put this circuit in a box as a measurement instrument, or you can...
Here is the latest and abundantly bigger TX200 VFO/VCO FM transmitter. The best able transmitter to date that can be angry into aerial allegiance stereo PLL based 200mW FM transmitter. It is a absolute ambit for transmitting your music about the abode and....
The circuit of Suzuki GSX1300 Hayabusa Charging System composed of generator, regulator/rectifier unit and battery. The AC current generated from the generator is rectified by the rectifier and is turned into DC current, then it charges the battery. While....
The circuit is basically a radio frequency (RF) oscillator that operates around 100 MHz. Audio picked up and amplified by the electret microphone is fed into the audio amplifier stage built around the first transistor. Output from the collector is fed into....
If a circuit is to switch a mains voltage, a relay is a simple solution in cases where switching times are long and high currents are involved. However, at lower currents, and in particular where rapid switching is required, such as in sound-to-light....
This circuit is two wire light level detector, we don`t separate wires for power this sensor system and for delivering the output signal. With current loop, we...
The mixer is really handy for DI`ing guitars and basses into soundcards or other mixers and making use of channels on mixes that do not have mike in`s, it comes in handy for one or two guitarists that want to sing and play through one guitar amplifier as....
