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 purpose of the terminal interface is to allow my computer to communicate with Minimum Mass...
Dc power can also be controlled via fiberoptics. The circuit provides an insulated speed control...
This circuit turns on the brake lights of a parked car when the headlights of an oncoming car...
This linear amplifier delivers 10-W PEP output; with 1.25-W drive on 10 m. Tl, T2, and T3 are 10...
The circuit is built around a 555 oscillator/ timer. The circuit provides two time periods. The...
The second circuit simulates the siren of an American police car. It uses two 555 timers in the...
Fast rise-time high-voltage pulses have many uses ranging from EMC testing to device...
The Camera1 module provides a RoboBricks2 bus interface for a General-Vision Cognisight MTVS...
The amount 1. is a block diagram for agenda alarm and agenda thermometer. It consists of 1...
The EN line is called `Enable`. This control line is used to tell the LCD that you are sending it...
This is a very basic circuit for flashing one or more LEDS and also to alternately flash one or...
This device is a simple timer, allowing to keep on the headlights of your vehicle for about 1min....
A dimming control circuit generates a dimming control signal for determining brightness of at...
The actual anti-theft system is equipped with two frequency siren and connected to a vehicles...
By LK16-5/31 type master controller and PQY1 Series Magnetic control panel consisting of a...
