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.....

The JFET Pierce oscillator is stable and simple. It can be the clock of a microprocessor, a...
The circuit is designed to operate at 25 kHz. The data stream turns the 2N4401 hard on or off...
Transistor Q1 acts as an amplifier for condenser microphone MIC1. The output of Q1 is applied to...
This is NIMH Battery Charger using IC LTC4060 Electro Suite, a NIMH battery charger which is...
A very simple and high quality TV transmitter circuit based on IC MC374 is shown in this article....
Timing capacitor (C1) produces several times constants which is used to allow large voltage...
This is a very nice amplifier design and it is very difficult to improve it. I am glad about...
The first BC109C transistor (left hand side) is acting as a buffer. It provides the circuit with...
A solar charger for an iPod is no more difficult than making our Solar battery charger. Built in...
This is one of the smallest and neatest FM transmitters to be presented as a construction project...
This toy traffic signal uses a single low-cost hex Schmitt-trigger inverter IC (IC1a-IC1f) to...
Automatic Humidifier can be used to control humidity control family, it can also be used...
CL type neither is a power amplifier output capacitance and feedback capacitance nor...
