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.....

A portable FM transmitter that can be used to replace a FM microphone. This simple transmitter...
his coil is home-made. It is actually a single layer 'tapped' air core coil. Please refer to my...
This project arises from the need to home-build a valid tuning control for a multi band...
The shift pulse amplitude is less than 15 volts. If a stage is off, the shift pulse will not be...
The circuit will accept a video signal, separate the sync pulses, invert the video, and add new...
FM radio antena amplifier circuit diagram. This amplifier will pull in all distant FM stations...
An analog VU meter is often included in the audio equipment to display signal levels in volume...
Bored of playing around with capacitors Then its time for you to move on to super-capacitors....
Experiments with couple of floppy drives I have and it appears that on the step pin, current is...
This circuit can be used to escape from the nuisance of mobile phone rings when you are at home....
Using the LM3410 constant current LED driver is a monolithic IC we can design, many high...
This circuit takes two separate line-level stereo (L & R) signals and combines them into one...
It is sometimes necessary for an RC (remote control) model to contain some kind of switching...
This oscillator circuit permits crystals to be electronically switched by logic commands. The...
Applications are given to complete the four-piece HL402 switching power supply system diagram...
