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.....

Amplifying and limiting of the AM carrier is accomplished by the if gain block providing 55 dB of...
The oscillator output of the XR-567 can be amplified using the output amplifier and high-current...
Using a 6BW6 vacuum tube, the above transmitter delivers about 5 W output. CI is adjusted for...
Designed in the fifties, this pre-amp remained in production until 1975. And, it remains fully...
Voltage controlled oscillator (VCO) is similar to a voltage to frequency converter (VFC), an...
The circuit shown below can be used for measuring frequency or Hz. The IC is very simple to make...
The ISL62391 controller generates supply voltage for battery-powered systems. It includes two...
This device can`t be legally hooked up to the PSTN as there is all sorts of red tape you need to...
By the regulator and the regulator circuit silicon resistor formed Simple voltage regulator...
Electric blankets circuit controlled by the switch S, when the switch S full, 2ZOV entire supply...
