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 22 watt amp is easy to build, and very inexpensive. The circuit can be used as a booster in a...
A resistive voltage divider is used to establish a bias voltage for the input (Pins 2 and 3). The...
Compression and expansion ratios other than 2: 1 can be achieved by the circuit shown. Rotation...
A medium current switch mode power converter, designed for powering of superconducting loads...
A series capacitor worked best for low impedance loads while a parallel capacitor was used to...
This circuit uses a 555 timer which is setup to both runn in an Astable operating mode. This...
The Allegro ® A8732 is a Xenon photoflash charger IC designed to meet the needs of ultra low...
A device through which an electric current flows and which changes electrical energy into another...
A 1999 Pontiac Montana. The information console that shows temperature, MPG, compass, etc. failed...
Here is the design of an audio oscillator that runs at approximately 1 KHz. I don`t remember...

This project is a combined temperature and humiditymeter. It is an improvement on my PIC-based...
This wideband jammer simultaneously blocks all transmissions within a desired band typically by...
Many later radios use four 7-pin valves and require a 90V HT supply at typically 12mA and a 1. 5V...
