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 new design of a tutorial board based on the popular PIC16F84A microcontroller. It...
The comparator has an output pull-up resistor RL and is connected up to operate as a Schmitt...
The data separator is intended for use with 8" flexible diskettes with IBM 3870 soft sectored...
This circuit is often used by amateur radio operations, shortwave listeners, and other operators...
With IC SLB0586A from Siemens you can build a simple touch light dimmer circuit that will allow...
This sketch sends an ASCII A (byte of value 65) on startup and repeats that until it gets a...
The circuit is bell timer. This new project uses AT89S52 microcontroller and I2C EEPROM to store...
Even power device is made to provide energy to some pc. It really is usually devised for...
Here is a circuit Power Amplifier with output power of more than 600 Watt speakers with impedance...
When S2 is ON, the circuit here operates as an astable multi vibrator and the LED is lit for...
