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 is a 0 - 6 MHz DDS VFO controlled by a PIC16F84 (or `C84). The VFO is separated into two...
The uWatch comes as a kit of parts. All of the electronic SMD parts on the PCB are pre-assembled....
This circuit is a 20W Audio Amplifier kit, based on the TDA2005 IC, a class B dual audio...
Capacitor C1 is charged through timing resistor R1 when the clock output is high. When C1...
The above circuit will charge any 2-cell * Li-Ion battery pack. Maximum current is about 650...
Here`s a very simple, but practical circuit, which is used to check the type of LAN cables...
This quad amplifier is actually intended to be used in a car, but it can naturally also be used...
Most homes today have at least a few infrared remote controls, whether they be for the...
To measure the frequency response of the e-meter, a Wein Bridge oscillator, oscilloscope, and...
This is an automatic emergency lamp with day light sensing, means it senses darkness/night and...
The circuit below illustrates using a 10x10 matrix to sequence up to 100 LEDs with just three ICs...
This power monitor device provides accurate voltage and current monitoring of positive supply...
In single phase AC induction motors, often used in fridges and washing machines, a start winding...
The following schematic shows the JFET- Bipolar Cascode Circuit Diagram. The JFET- Bipolar...
