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 time delay relay is a relay that stays on for a certain amount of time once activated. This...
This economical signal tracer is useful for servicing and alignment work in receivers and low...
In this circuit, IC1A and IC1B act as a monostable multivibrator. Any input from the sensors SI...
This AC Power Monitor continuously watches the AC power line voltage for both under-voltage and...
In a traditional microstepping motor controller, many parallel outputs of a microcontroller are...
Pulse motor or stepper motor step motors, foreign, or commonly known as Step motor Stepping...
Monostable 555 timer multivibrator circuit (one shot monostable multivibrator) is a retriggerable...
Here is a simple but effective intercom circuit that is based fully on transistors. The circuit...
This Class E RF amplifier will deliver up to 400 watts of RF output, depending on the input...
This circuit controls a load (in this case a dc brushless fan) based on a temperature compared...
With pulse operation, the solenoid is energized momentarily with five to six times its rated...
To increase one`s chances of seeing the northern lights, the uncertainties of existing aurora...
It is well known that through such simple everyday activities as walking on a carpet or moving in...
Most models produced in the 30s rely on very similar circuits; in particular the RF section of...
D1, D2, C1, and C2 double the AC line in, charging C3 through R1 to approximately 320 volts. R1...
Video switcher circuit is needed to display more than one display in one monitor. Take a look at...
Cats are predators of rats, the use of electronic devices to simulate mew Repeller is an...
