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.....

This project is a digital Automatic Gain Control (AGC”) system using a PIC16F876 MCU. The...
This unity-gain follower amplifier has a CMOS p-channel input, an npn second-gain stage, and a...
This is the door bell circuit with flashing LEDs to make the circuit more attractive. IC1 (NE555)...
This is a figure for a block diagram of a modern automated systems incorporate closed-loop...
Based on this `manual` PCR machine I built a few weeks ago, the Light Bulb PCR machine uses a...
The operation of the circuit starts up and transport the stereo surround sound signal quality...
Even if a large number of album titles once available on vinyl are now, little by little, being...
It is easy to install 6E5 on the place of oscillator tube because socket`s pinout of this amazing...
The entire control is handled by a Microchip PIC18F46K20-I/PT microcontroller, programmed with a...
The figure shows a simplified schematic diagram of main circuit DMA12. It is mainly composed of...
Due to the lack of speed in the entire series TTL monostable multivibrator, and because of the...
Acoustic detector consists of a Schmitt trigger IC555 connected components. Just input exceeds a...
Conventional digital home theater amplifier requires the use of a dedicated integrated circuit,...
