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.....

Infrared interruption counter is a reliable circuit that takes over the task of counting number...
Capacitor C5 and potentiometer R12 determine the frequency of the output signal at pin 3 of IC1,...
Ql and Q2 constitute a simple, high-speed FET input buffer.·Ql functions as a source follower,...
Ul is an op amp used as a comparator. When the test probes are shorted together, resistors R1...
This circuit provide automatic current limiting up to 8. 4A. Unlike current limiter that uses...
If you have a servo and you wan`t to test it and you do not have a remote control to do that, or...
It is mainly composed of permanent magnet with the disk, integrated Hall sensor, strobe gate,...
This circuit will flash a bright red LED (5000 mcd) as an attention getting device or fake car...
Magnetic core memory was the most widely used form of digital computer memory from its birth in...
T1 transistor must be BF200 type (or similar ) and the other transistors can be BF214 type. For...
An obstacle avoiding robot is an intelligent device, which can automatically sense and overcome...
This circuit is based on the 7240 CMOS programmable timer chip (IC3), which has an accuracy of 0....
A real cheap glove interface, that still achieves considerable accuracy while improving the...
