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 a handy companion for a digital voltmeter. Its allowed me to do a lot of things I used to...
The circuit will operate reliably from below 1 MHz to above 400 MHz. With Vcc = 5 V the output of...
This circuit has a 100 mV hysteresis which can be used in applications where very fast transition...
Only one channel of this circuit is shown. The other is practically a carbon copy.The input to...
The CD4001 quad 2-input NOR gate is a very versatile IC that can be used in an almost infinite...
I did some quick playing with the circuit. It is very close to sustaining oscillation. Changing...
You already appear to have sufficient snubberring around the TRIAC which should eliminate DV/DT...
This is the circuit diagram of touch activated alarm system which still activated on load...
It can be used as part of intercoms, walkie-talkies, low-power transmitters, and packet radio...
Most of the telephone security devices available in market are simple but quite expensive. These...
This is a aerial achievement low babble 500mW amplifier / booster for all low ability FM...
FM Radio has a long history to its credit starting from its development in 1933. Today, FM Radio...
This is a fun and non-dangeros project for those people who like to throw projectiles...
Shown for the 2W audio power amplifier. The circuit uses a 14-pin package LM380 as amplifier...
As shown, the circuit due to the integrated amplifier, so the circuit is simple, small size....
Color light-emitting diodes with different colors of light can indicate the operating electrical...
