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 second gate (G2) of a MOSFET can be used to incorporate a crystal oscillator into the same...
The telephone-line tester consists of nothing more than a meter (that`s used to measure line...
Multiplexed displays are electronic displays where the entire display is not driven at one time....
Burst Mode operation maintains high efficiency at light loads by reducing IC quiescent current to...
The MK-219 is a popular large-diaphragm condenser, designed and produced in JSC Oktava`s factory...
This white LED Driver circuit project is based on the NCP5680 high efficiency white LED Driver...
Here we describe a simple process to `put a voice on a sunbeam` and transmit it over a distance....
Using LM386 power amplifier designed for use in low voltage consumer applications can be designed...
It will allow your car headlights to flash on and off at the same time or it will cause them to...
Back panel terminal connectors: Audio out, Trigger In, Clock In, Clock out CV out; plus the chord...
The Sovtek 5881s that come in these amps are cheap and sound like it. Change ALL tubes. Get a...
Connect a 12 volt 20 watt lamp and 12 volt battery to the circuit (observe battery polarity)....
This circuit is designed to operate an electrical door-release mechanism - but it will have other...
This small circuit transmitter processes the signs of audio of a sound table or microphone, and...
