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 CMOS circuit can be used as a 1-shot time delay switch and general-purpose timer. The...
The circuit can be used to tell whether or not an input signal is within a certain frequency...
Monitoring a flame and directly switching a 120-V load is easily accomplished using the Ll4G1 for...
Two gates of a 4011 arc used as a comparator. When the resistance of R4 decreases the voltage at...
The IQ_Demod project illustrates the use of the IQ_Demod_Setup and IQ_Demod_Data components in...
The impedance of these current generators is essentially infinite for small currents and they are...
Here is a high sensitive touch plate circuit using NE555 which turns on a buzzer when anyone...
H-Bridge and Half Bridge Driver IC TLE6282G Application, Dedicated for DC-brush high current...
Everything works just great. The final software is 930 lines of assembler. I also learnt how to...
The Measured Value and The Setpoint are two inputs to a Control System. The Measured Value is the...
The Advanced Laser Diagnostics Laboratory (ALDL) specializes in the development and application...
Before one magnet was 2x2x3 cm, now it is a round one 1. 5 x 2 cm only. This makes a huge...
As shown for the low-frequency output 7W power amplifier circuit. The circuit uses a FET input...
