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 signal booster, built around a few transistors and support components, offers an RF gain of...
At a predetermined level of declining terminal voltage, the circuit disconnects the battery from...
This project involves constructing an energy efficient broad spectrum LED lamp system. The lamp...
This is a simple low-cost 50W off-line switching power supply, which can be used for home...
A cure that we are testing is to prevent the over voltage getting to the irreplaceable IC U5 -...
This circuit changes the gain of opamp U1B in four steps or segments. It can be used to get a...
The UTC H1277 is a semiconducting integrated Hall Effect Sensor IC. It is just like all the hall...
When the games timer is RESET, two things must happen. The 4017 counter must go back to zero and...
A number of operational amplifier circuits are provided here that are set up to be squarewave...
This circuit uses a Cmos 4017. The 4017 is a decade counter. The count starts at zero. And it...
As shown by W317 is being integrated three-terminal adjustable voltage regulator circuit...
