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 completed board may be driven by voltages between .8 and 3 Volts. While the basic design goal...
You may be familiar with this effect. You switch audio equipment such as an amplifier to a...
This circuit will run from a single 5 V power supply. The LTC1043 switched-capacitor...
The length of time the circuit stays on for depends on how long it takes for the stored...
This is circuit for accurate time-base generation using the readily available 3. 5795MHz crystal...
Make this temperature controlled fan and since i am using 15V AC power supply instead of 230V AC....
Here is the circuit diagram of simple and easy subwoofer filter which will be operated from a 12V...
The heart of this circuit is a crystal oscillator. A 10MHz crystal is used to produce highly...
A very simple FM CB radio receiver can be designed using this electronic diagram below. This FM...
This touch sensor switch can is designed using inverters (N1, N2)and some common electronic...
Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal...
You could have an USBI2C with every sensor, which would mean 4-sensors for £120. The SRF02 runs...
