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.....

We chose to build a nightlight combined with a wake-up alarm. Our nightlight features not one,...
utilize RGB LED lightsources, an optical sensor and feedback controller. The aim of using optical...
Cigar Lighter Plug to USB Power Socket. This circuit is convert 12V DC source from car cigar...
The count advances as the clock input becomes high (on the rising-edge). Each output Q0-Q9 goes...
The induction coil forms part of the anti-sidetone circuit. It couples audio to the receiver, and...
The printed circuit board, has a pin strips (10 pin x 2) used to connect with the circuit board...
Four 4, 8 Volt 2000mA Nickel Cadmium batteries. Does anybody here know a safe way of initial...
This is a car alarm simulator which using the LED as a simulation output. This simple circuit can...
When one of the normally-open switches is closed - two things happen. Firstly - the negative side...
It uses pattern SH803 flash IC, within reservoir eight kinds of programs and a variety of...
