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 Keypad must be the kind with a common terminal and a separate connection for each key. On a...
A CA3240 dual MOSFET-input device is used as a white-noise source. Op amp IC2 is used as a driver...
What you will be seeing here is a circuit diagram about the electrical wiring diagram of the 1986...
Develop a cheap high-current circuit and still use PWM. Specifically, did I get the flyback...
To take advantage of sunlight shining on the earth can continue to be utilized to serve as a...
This 6" x 18" clock needs 52 light sources. It may one day allow humans to know the time without...
The purpose of this circuit is to power a lamp or other appliance for a given time (30 minutes in...
This circuit was designed as an aid in parking the car near the garage wall when backing up. LED...
The LTC4251/LTC4251-1/LTC4251-2 negative voltage Hot Swap controllers allow a board to be safely...
The goal of the project is to create a robot that will follow a black line on a white sheet of...
This type of travel may be possible if two space points can be connected by a vortex channel in...
As we all know, if the power transformer neutral line circuit, and when the three-phase...
