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 is a general-purpose 10-W audio amplifier for moderate-power PA or modulator use in...
Now-a-days every institution needs automation. As a part of college automation, we have decided...
The circuit drives the LCD pins with 50% square waves. Each segment on this LCD is connected to...
TCA965 window discriminator IC allows the potentiometers RVl and RV2 to set up a window height...
A very efficient buck boost converter circuit is shown here. The circuit is based on the LTC3440...
This circuit turns-off an amplifier or any other device when a low level audio signal fed to its...
The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of...
On the bottom you will see a 74AC125 which is a Quad Buffer with Tri-State Outputs. I`ve seen...

A frequency-selective frequency multiplier can be construct with a PLL system by inserting...
The test beeper generates a sinusoidal signal with a frequency of 1, 000 Hz, a common test...
This Basic MOSFET amplifier is very simple to build and low cost. Is perfect for Hi-Fi amplifiers...
In this circuit SP6126 is configured as a Zeta converter to provide 0. 3A for driving four...
The DIY Electronic Siren circuit described here can create three different US-style siren sounds:...
The microcontroller board is shown (top left/green board) along with the auxiliary board (bottom...
Circuit is shown. It consists of language and sound circuit FM transmitter circuit. The entire...
D2025 Dual audio power amplifier circuit D2025 is a stereo audio power amplifier integrated...
