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 main power supply to the system must be a regulated 12 volts DC with a minimum input from the...
This simple circuit can detect the invisible fields of voltage which surround all electrified...
The sensing circuit rapidly disconnects the battery voltage and load whenever the voltage drops...
In my previous post of capacitive touch switch, it gives the o/p as long as you touch it. Means...
Wolfram SystemModeler ships with model libraries for a large selection of domains such as...
The optical key works as an infrared door opener for house, garage and the likes. Diagram 27. 0...
Ok, its been a while since I did much more than think about my micromouse, but over the last week...
The NP-100v12 is a simple headphone amplifier that allows an entry level builder to experience...
All the naturally occurring phenomena like sound, temperature and pressure etc, are analog in...
This is the circuit diagram of a ding dong sound generator based on two NE555 timer ICs. The...
The drop-down category menus above may help you find what you are looking for. Be sure to also...
Simple and easy to do single flashlight battery DC-DC driver circuit and leave the battery...
Semiconductor thermistor embedded thermal protection element belongs, it is sensitive to...
Environmental noise monitor circuit is shown. It mainly consists of high gain mu Specification...
