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.....

Vinyl equalisation (EQ) has been with us in a stable and predictable form for quite a long time,...
This Project is made up with AT89C2051 and the RTC DS1307. It has a large Seven segment display....
The 20-MHz clock phase-locks to Apple"s Mac II 10-MHz NuBus clock. It uses a simple, inexpensive...
In this mode, the timer functions as a one shot. The external capacitor is initially held...

This page describes a dual axis stepper motor controller design and printed circuit board for an...
This the circuit AC dimmer low voltage For lamp 6V. While this friends may don`t see the...
This circuit provides a visual 9 second delay using 10 LEDs before closing a 12 volt relay. When...
This is the Sequencer circuit. Power to the Logic portion of the circuit is provided by a...
This inverter can deliver high-voltage ac or dc, with a rectifier and filter, up to several...
Had bought this EDE702 some time ago, and a LED-backlit LCD character display. After buying the...
As shown is a very attractive Christmas lights circuit. When the power is turned on, lights HL...
Ceramic gas sensors can also be used to analyze the content of alcohol vapor. With the...
