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 circuit will provide an indication whenever the input voltage differs from two defined...
Using inexpensive components, you can fit a simple probe circuit into a pencil-sized enclosure....
The Above circuits are based on TEA2025 is a monolithic integrated audio amplifier in a 16-pin...
This compact metronome will run for years on a single nine-volt transistor battery. Has both tone...
The circuit uses a four-bit latch (Ul). What makes the circuit sequential is that the set input...
The heart of the switch controller is an Arduino Nano micro-controller - this is going to be the...
As more than one switches are to be controlled, we have to transmit a number of bits through IR...
This circuit is especially designed for those who often need to wake up early in the morning....
Crap, the sensor on my clone is low resistance and the replacement heater is 45 Ohms. Is there...
Tennis for Two presented a tennis court shown from the side on an oscilloscope screen, where...
This design allows to operate two intercom stations leaving the operator free of using his/her...
This circuit uses the popular and easy to find LM3914 IC. This IC is very simple to drive, needs...
FIG. 2A3A low direct thermal resistance transistor, its resistance is only 800, so the output...
