The input signal drives ICD. Because ICD"s positive input (V+) is slightly offset to + 0.1 V, its steady state .. -
The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in responding. Converting....

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.....
The simple circuit of Fig.1 emulates a similar conjuring trick which sells for hundreds of...
This supply generates an initial high voltage for ignition purposes. After ignition, the supply...
The battery charger circuit below is very simple to build requiring only a handful of cheap parts...
This simple AVR Programmer able to transfer hex programs to most ATMEL AVR microcontrollers. It...
The principle of operation of the proposed metal detector circuit is quite basic yet very...
The XR2206 Function Generator>(Sine-Triangle-Square Waveform Generator). The frequency range is...
Circuit Here is a circuit of a remote control unit which makes use of the radio frequency signals...
Designed with an output voltage swing of 350mV at better then 400Mbps into a 100 ohm load, across...
This design is for PC Soundcards obviously. If you need an interface for a Mac see my other page....
This circuit delivers a plentitude of noise, a veritable harvest of noise, yes, I dare say. an...
The circuitry for the tone detector, solenoid driver, and motor speed control (paper transport...
