The circuit shows TL494 Pulse Width Modulated Step?Down Converter Circuit Schematic. With this circuit you can have circuit test such Line Regulation, Load Regulation, Output Ripple, Short Circuit Current and Efficiency test with various Vin conditions..... -
This is a circuit of Voltage-to-Pulse Duration Converter. This circuit is used to convert voltage into pulse duration by combining a timer IC and an OP Amp.. -
The circuit is temperature to pulse width converter. The LM3524 to convert the output of an LM135 temperature transducer into a pulse width which can be measured by a digital system, such as a microprocessor controlled data acquisition system. In this.... -
This circuit receives the signal from the above amplifier and launches powerful 1uS infrared light pulses from a low cost LED that are frequency modulated by the audio information. The 10KHz center frequency of the pulse stream is low enough so a standard....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
This is the design circuit diagram of an ultrasonic mosquito repeller. The circuit is work with...
This infrared detector circuit is designed using the PID20 integrated circuit manufactured by...
This scheme is for 4 cylinder motor. This will make your car spent less fuel, be a little bit...
I bought a Doepfer LMK3+ keyboard from a very pleasant chap in Dunedin, via TradeMe, a popular...
For some ten years Texas Instruments have been developing solid state speech technology with the...
The circuit I used is a very common one. You can do a google search for 555 timer LED blinker ...
The ambit of AM transmitter is advised to address (amplitude modulated) DSB (double ancillary...
The circuit of active shortwave antenna presented here boosts weak shortwave signals so that...
The full GSM thermostat is managed by a Microchip PIC18F46K20-I/PT microcontroller, programmed...
The Shay is equipped with flickering ashpan and firebox lights. These are simulated with LEDs....
A cellular rotary phone - the dialing takes forever! And here in Colorado - on a 10-digit dialing...
