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 headphone buffer is based on Greg Szekeres' MOSFET Headphone Driver. It is a robust and...
When SI is on, power is applied to an oscillator composed of Ql, Rl, Cl, LI, and L2. Coil Ll is...
The circuit can be used as a sensor that can trigger an alarm, without direct contact being made...
A highly-stable 60-Hz sine wave can be delivered with this circuit, which offers a different and...
Achieve communication between MCU and accelerometer trough I2C nor SPI. I observed that shorting...
The aim of this project is to transmit analog sound from a commercial mp3 player digitally using...
This Chip from TI is simple to accommodate into your designs and this band-aid is acceptable for...
Here is a simple circuit that can be used to check the sound levels. The sound pressure meter is...
This circuit shows that dimmers intended for use at mains voltage do not always have to contain a...
The objective of this controller project is to have automatic block and switch control of five...
After the restructuring of AC and DC arc welding machine circuit On the BX series AC arc welder...
Although the respective inputs are differential inputs, but the right amplifier is greater than...
Circuit shown in Figure 3-171. The figure, the auxiliary power supply is single-phase AC power,...
