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 digital storage oscilloscope (DSO) is a very important piece of test equipment that...
Hand and body motions in proximity to the sensing antennas produce frequency changes in a Hartley...
This voltmeter exploits a number of tbe CA3160 BiMOS op amp"s useful characteristics. The...
On occasion, microprocessors/microcomputers and microprocessor crystals just aren`t compatible...
This CW transmitter has an output of up to 3 W. By using 24 V on Q2, up to 10 W output can be...
Man has long wrestled with Time. Also, with knocking on things and not getting the time of day....
The following diagram is the Clock Generator circuit diagram which build based on NAND Gate logic...
This circuit, which uses a CD4538 retriggerable monostable multivibrator and a CD4011 NAND chip,...
I tried photo paper, telephone book paper, color pages of magazines, dextrin covered paper, the...
At the heart of this heat-sensitive switch is IC LM35 (IC1), which is a linear temperature sensor...
You can test the board now. For example set the DIP switch to Switch1 ON, Switch2 OFF (15 sec...
Using this circuit, audio musical notes can be generated and heard up to a distance of 10 metres....
The circuit can drive the companys Dialight 745-0005 monitor, which is a word composed of 64...
