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.....

Astable or free-running multivibrators have been used in home-built amateur radio equipment for...
Because the CS5501 16-bit-delta-sigma analog-to-digital converter lacks a start convert command,...
Chrono or Chronograph, the term used by Airsofter and Paintball players to refer to the device...
If you want to create the 100 watt OCL audio amplifier circuit. I want you to consider this...
The two circuits below illustrate generating low frequency sine waves by shifting the phase of...
When VOUT is very low during start-up or a short-circuit fault on the output, the switching...
This quad amplifier is actually intended to be used in a car, but it can naturally also be used...
If you ever thought of experimenting with pulse-width modulation, this circuit should get you...
The CDCF5801 provides Clock multiplication from a reference Clock (REFCLK) signal with the unique...
The strategy is to get the circuit going in stages, testing each part as you go. Once everything...
