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 remote solar powered LED light takes advantage of the current limited nature of solar...
Connecting a LCD display to your personal computer is an easy job. Displaying data from your PC...
Up to 10 A continuous output current, or operation with 50 % ESD and 18 A peak current are...
The telephone-line decibel meter and line-voltage sensor shown lets you accurately monitor and...
This is an excellent Hi-Fi Stereo PLL FM Transmitter, the audio source can be the computer, sound...
FM radio receiver circuit is an FM receiver made by IC TDA7000. The circuit uses IC TDA7000 FM...
This project uses just one tube. However, the tube chosen (13EM7) actually contains two separate...
Tuned circuits consist of C4, L1, C8, L3, and the two 15 pF trimmer capacitors across the...
the rest of the pictures show the construction of the sub. It was made out of two C channels...
This is a very simple circuit where the PIC and an internal 1kHz sinewave table do all the hard...
As water heaters, microwave ovens and other heating equipment temperature control circuit;...
DC relay or contactor in addition to using strong excitation pull way accelerate, accelerate the...
