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.....

Realistic flap and landing gear actuation. This circuit slows the speed of a conventional...
The logic designer is filled with features. It would not be possible to list all the possible...
An RF isolator is a seemingly magic device that allows signals to pass in only one direction....
This version of the Link uses DTMF tones for dialling both internally between handsets, and...
A shortcoming of the above bi-directional proportional motor control circuit is that with the...
Most circuits that provide an electrical stimulus for research subjects are constant-voltage...
The NE555 circuit is a basic one-shot timer with a relay connected between the output and ground....
The base of Ql is connected to the car`s ignition circuit; the easiest point to make that...
Electret mic pre amp schematic. The op amp provides an amplification of about 30 dB (which is...
The Hartley oscillator is an LC electronic oscillator that derives its feedback from a tapped...
This was a final project for an optics class EE 134 at Stanford. It was an open-ended project to...
This a application circuit for calibration. This circuit is called high voltage AC calibrator...
ISP Programmer Please buy USB programming cables at last and start using AVR Studio, avrdude etc....
If you wish to use a double power supply but don`t have a center trapped transformer you can use...
A 1971 lincoln continental 4dr, i am getting no power inside the car mainly ignition switch, i...
Always use shielded LWDAQ Cable to connect the A3018 to the LWDAQ Driver, not Ethernet cables....
Can alkaline batteries charging problem, there are two different versions. Some say you can...
Circuit Description: Transistor can amplify the input signal. Then two diodes clamp distorted...
