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.....

This photocell is best mounted at tie level between the rails. The variable resistor adjusts the...
This circuit converts frequency to voltage by taking the average dc value of the pulses from the...
This circuit is used for remote photographic flash units that flash at the~ame time as the flash...
The SillOO series circuit input is connected to a capacitive field sensor-possibly a piece of...
In this circuit, Ul is a frequency converter that feeds the 455-kHz IF stage U2 and detector
Cascading two identical integrators will thus result in an overall phase shift of 180° and an...
This meter differs from the norm in that it does not use a D`Arsonval movement or digital...
The circuit uses the very popular Sharp IR module (Vishay module can also be used). The pin nos....
Clock signals are the heartbeats of digital systems. Hence, the stability of clock signals is...
A very simple battery charger circuit having reverse polarity indication is shown here. The...
Build a sine wave generator. I use this schematic:. The op-amp I have used is the TL082 and the...
FS810 practical circuit as shown for the integrated power amplifier. FS810 is a high performance,...
