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 circuit is built around a 4001 quad two-input NOR gate, it provides switch selectable...
This project illustrates how to use an ATTiny microcontroller and an RGB LED to create a coloured...
This device is designed to be a simple, inexpensive comparator`, intended for use in a solar cell...
Amplify a MG811 CO2 sensor to a range readable by an ATMEGA2560 (0-5v). I have other analog...
The Amplifier circuit can be made with an IC power amplifier LM1875. IC LM1875 is a single chip...
Another application of FVC (frequency-to-voltage converter) is tone/frequency decoder. This...
This timer was designed mainly to switch off a portable radio after some time: in this way, one...
This is a MOSFET transistor based power amplifier circuit that can be operated between +35V to...
Jim took the original EMT 140 design and improved it by using a plate material with a brighter...
The diagram below shows that power supplies don`t have to be complicated, especially in low-power...
A notch for a narrow frequency band of a few per cent or even less normally requires...
