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 wide rage auto turn OFF timer covering 1 minute to 20 hours in three ranges with S1. As soon as...
By utilizing both halves of a dual timer it is possible to obtain sequential timing. By...
This circuit is useful if you need a low-energy flashing alarm. The 200 to 400-dc supply should...
This circuit is similar to the one above but uses positive feedback to get a little more...
A 6 watt audio amplifier circuit using TDA2613 is shown here. TDA2613 is an integrated Hi-Fi...
Using electronic scheme below can be designed a zener diode tester using few electronic parts....
When ever you need to get an alarm or intimation after ten minutes, the circuit shown below can...
Built quickly from the parts found on my home lab, seemed to work on short test with telephone...
Circuit for Grundig 5441 tv. If you have any problem regarding this issue come back with more...
The kit includes the following items (depending on which bootloader chip 16MHz or 8MHz) The kit...
An electrocardiogram or ECG (also known as EKG ” abbreviated from the German word...
When the input goes from low to high, a narrow positive pulse is generated at point A. This pulse...
This project implements a USB device which provides a real-time clock for the purpose of...
In order to obtain wax dB / oct low pass filter of Butterworth times, the four 12dB / oct...
