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 heart of the circuit is the tone (pitch) display section, based on the popular LM3914 display...
This project has two options. It can be a mains operated project, using a 2155 or 2156...
A bidirectional H bridge DC motor control circuit is shown here. The circuit is based on the IC...
In this part of the inquiry in a series of 5-band Equalizer circuits with a single IC BA3812 L. a...
Following a highly successful Kickstarter project and over a year of development, HexBright,...
a Pierce "aperiodic" oscillator driving a non-neutralized power amplifier for a multiband Morse...
This circuit is Wein Bridge Sine Wave Oscillator. The main problem in producing low distortion,...
One of the most useful gadgets a video enthusiast can have is a low-power VHF TV Transmitter....
The following circuit shows a RF Remote Control Circuit Diagram. This circuit based on the HT12E...
The oscilloscope is still one of the most important measurement tools of the electronic engineer....
This is small inverter on 30 watts, It converts DC voltage from 12V battery to AC 220V-230V at...
A clock using numeric neon lamps, also known as nixies. These display devices were common around...
To build astepper motor tester, the circuit contains two sets of drivers that can support both...
The MAX3420 is a USB peripheral controller chip with an SPI bus. This page hopefully contains...
Every cheap energy-saving lamp has a self-resonant voltage inverter inside. They are designed for...
