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.....

Atmel described a simple programmer based on the AT90S1200 (NOT the AT90S1200A) controller in...
Two simple arrangementsfor resistive loads are shown in A & B. The circuit in A will provide load...
This lighting-control unit will fade out one lamp while simultaneously increasing the light...
The back to back diodes are there because some radios present high voltage transients when...
Tape isolate single-phase PFC that DC/ DC vary make up, make up two cable, PFC of three-phase,...
In those circuits a set of switches (conforming to code) are pressed one by one within the...
This example describes use of HS101, HS201 radio transmitter and receiver modules made of...
Here is the circuit diagram of a simple stepper motor controller using only elementary parts. The...
A 12v DC electromagnetic lock with push to lock and push to unlock using my existing LED...
Fluorescent tubes use far less energy than incandescent lamps and fluorescent tubes last a great...
