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 circuit will remove the transient spikes and contact bounces from a non-latching push button...
This circuit uses a positive-feedback loop closed around~a combined comparator and integrator....
This circuit, a simple mixer circuit. It can mix two signal channels and one channel is output....
This is a stereo amplifier circuit diagram. The amplifier will produce stereo output channel with...
This circuit is derived from an application note of L296, It is a Power Switching Regulator from...
This Dummy Alarm project makes an LED flash briefly once every 5 seconds to imitate the indicator...
This project was developed as an inexpensive way to drive small dc brushed motors as positioning...
This is the diagram of VHF RF Preamp circuit 100-175 MHz with single chip MAX2633. The circuit...
Many low pass filter circuits for subwoofer are given here and this is just another one. The...
The drawbacks of pi-filters are the comparatively larger cost, more weight, bigger size and...
This is a quick how-to guide for making a stereo VU meter using the LM3915/LM3916. The LM 3916 is...
AC to DC circuit is a sinusoidal alternating current into direct current crossing the circuit, if...
Specific remote control transmitter circuit composition shown in a diagram. Transmitter mainly by...
