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 circuit allows you to equlize the audio signals in ten band. It uses low cost op-amps to...
A Coil Coupled Operation Metal Detector made from readily obtainable components and using an...
These circuits are based on TEA2025 is a monolithic integrated audio amplifier in a 16-pin...
This 49-MHz FM transmitter consists of an audio amplifier, a low-pass filter, three RF stages,...
Let`s examine the statements that describe the equation. In part (1) of the statement, we see...
Motion detectors often we hear, is to use ultrasonic sensors, the advantages of this sensor is...
The circuit, consisting of an infrared transmitter-receiver pair, utilizes IR beam transmission...
The LT6552 is a video difference amplifier optimized for low voltage single supply operation. The...
The Mark III conductivity-temperature-depth (CTD) profiler has been the mainstay of modern...
To convert the MaCom 10GHz "White Box" (or "Whitebox" for the search engines) unit for ham radio...
This modification is to be done AT YOUR OWN RISK and there is no guarantee that the modification...
The circuit in the diagram enables a negative voltage to be derived without the use of integrated...
The back EMF voltage spikes produced by stepper motors (particularly higher voltage motors) can...
Pressure transmitter circuit data acquisition system by 1B31,18 bit A / D converter AD1170 and...
By ASIC it is a flashing light string web dig troller, which has four outputs; single key cycle...
