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.....

Oscillation frequency 10Hz ~ 20MHz, 6 ranges. Analog output Sine, triangle, square wave (0 ~...
This electronic level uses two LED indicators instead of an air bubble. If the surface is tilted...
The circuit can operate lamps and buzzers from the 120 V, 60 Hz power line while maintaining...
At the heart of the CD4-MX is an astable multivibrator, built around Q1 and Q2, that feeds...
Most ATV (Amateur Television) transmitters transmit a DSB signal and commercial television...
The Liquid Crystal Library allows you to control LCD displays that are compatible with the...
Make a 555 timer base circuit such that O/P pin of 555 is held LOW by default at power on, and...
This device just sends data about the state of our office to Twitter (mainly because it`s just...
A voltage regulator is designed to provide a fixed voltage to any load. Inherently this means it...
A very useful application of the 565 PLL is as a FSK demodulator. In the 565 PLL the frequency...
The following is one of the most rare and special documents here at the DigiBarn, the only known...
This TDA1514 audio amplifier circuit design electronic project is capable to provide a high audio...
As shown in FIG PGA103 constituted by a wide input voltage range of the amplifier. 11.3k with...
Bridge is a low frequency push-pull power amplifier circuit, its structure is very simple,...
Circuit shown in Figure 3-80. Which controls part of the transistor multivibrator. Multivibrator...
