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.....

This circuit is intended as a reliable replacement to thermally-activated switches used for...
TCP based security system using the Ethernet module offered within the contest , an ATmega16L...
The circuit allows a precision regulated drive current to be set to drive an LED, and in response...
When the power is connected to the circuit by turning on SW2, RELAY1 get energized for the time...
The current tracer helps locate a defective IC that is loading down the power supply. The tracer...
This circuit uses one of the LM389 transistors.to gate the power amplifier on and off by applying...
This is a one direction motion sensor circuit. This motion sensor circuit is used to detects an...
On this page we will discuss the power electronics needed for our EDM machine. The basic...
Because of the high voltages found in a Charge & Primary sections it seems natural to look for...
Diode, D13, provides different timings for the forward sweep, and the retrace which can be faster...
This class A preamplifier has been designed in a symmetrical structure. In the input differential...
Whenever AC mains supply fails, this circuit alerts you by sounding an alarm. It also provides a...
The purpose of this page and its sub pages about members of Z80 family (and close relatives) is...
The circuit uses AC mains voltage and otherhigh voltages that can cause injury or death. The 125...
This circuit reproduces the starting light sequence currently used by FISA for Formula One...
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at...
