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.....

When the tank is cleaned the fish are removed and placed in a small amount of the tank water. The...
For use with low-power transmitters with a positive keying voltage. Q1/Q2/Q3 form a switching...
In some of my previous posts, we have seen the simulations of half wave and full wave rectifiers...
The PSU you`re referring to doesn`t look extraordinarily large to me.Eagle should be able to...
the timer will generate the basic period (for example 20ms) and with some associated variables...
A SIM Card also known as Subscriber Identity Module, A SIM is a Smart Card that can store data...
The photo above clearly illustrates phase angle control: output voltage controlled by the gate...
This project started because I wanted a Li-ion charging circuit with more flexibility than...
For those who are lazy like me, turn on or off the bedroom light without getting out of bed,...
The circuitry for the tone detector, solenoid driver, and motor speed control (paper transport...
This article provides an overview of the R100 and MCR100 UHF repeaters. All of the information...
Here is another little circuit I designed for radiation logging purposes. It is based on an Atmel...
A company is given to ATMET 89C51 microcontroller core temperature intelligent monitor, monitor...
