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.....

A real analog synthesizer to build using easy to get components, capable of a wide range of...
LEDs indicate at a glance what the status of the circuit is at any given moment. Once the reset...
If you haven`t already read my CT-100 restoration article, I suggest that you start there. It...
This digital voltmeter is ideal to use for measuring the output voltage of your DC power supply....
This is a design circuit for intercom circuit. The circuit comprises a 3-stage resistor-capacitor...
Quiz-type game shows are increasingly becoming popular on television these days. In such games,...
This project builds a Christmas lights controller for the GE Color Effects lights allowing...
The LA3370 is a multiplex IC for FM car stereo, and it has the following 2 functions through its...
Everybody who regularly works with servos will know several instances when such a servo tester...
From what I understand, an SCR is like a diode that can either be turned on to act like an...
Most models produced in the 30s rely on very similar circuits; in particular the RF section of...
As shown in FIG TDA6103Q test circuit with feedback factor is 1/150. Input signal Vi1, Vi2, Vi3...
A two battery-powered light touch delay circuit, it can be placed on the bed pillow, nighttime...
