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 decision to use either AM, narrowband FM Oess than 15kHz), or wideband FM (greater than 30...
When power is first turned on, two of the LEDs are on and the other two remain off until the...
The current range in multimeters, particularly the more inexpensive ones, is restricted by the...
The baby-alert receiver is comprised of three transistors: Q2, which is configured as a...
The Arduino microcontroller board is able to supply a current of 40mA from its output...
Equipment designed to detect changes associated with fire, monitor the integrity of their...
It is one of the most popular type of oscillators used in audio and sub-audio frequency ranges...
This tester is designed to locate stray electromagnetic (EM) fields. It will easily detect both...
PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the...
A fairly simple "divide-by-1000" circuit which was first designed by Zeljko Bozic, S52ZB, in a...
This compact RF oscillator covers the entire 0. 4 - 30 MHz range in a single sweep of the dial...
As shown using MIC5156- is a composition having a current limiting function, and a lot of high...
As shown in FIG grounds ISO100 multichannel data acquisition system consisting of a programmable...
