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 circuit diagram of the Lie Detector is shown above. It consists of three transistors (TR1 to...
The circuit is built around two power FETs, which are configured as a simple astable...
This circuit allows a 4-to 20-mA current loop to control an isolated SCR drive. IC1A and are...
Here the 50W inverter circuit build based power MOSFET FQB45N03 and IC TL494. This inverter will...
Current meter used to measure the current from a solar panel. It has very low power loss for...
The optical key works as an infrared door opener for house, garage and the likes. Diagram 27. 0...
Diploma Final Year Project represents the culmination of our learning process, where it is a must...
In order to eliminate noise, I`ve used a 100uF capacitor and a 100nF bypass capacitor across the...
There are not many AM transmitters that are easier to build than this one because the inductor is...
Here is a simple circuit that can be used as a telephone status indicator. When the telephone is...
The clock described on this page is the result of both events, a simple single digit nixie clock...
The main ΣΔloop, which again operates in steady state, is fully controlled by summing comparator...
Using the ISL8012 high efficiency, monolithic, synchronous step-down DC DC converter can be...
