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.....

If the amp is built on bipolar transistors, and the preamp/crossover on FETs, then they were...
The circuit warns car drivers when the air temperature close to the ground approaches 0°C,...
The purpose of the circuit is to hold the peak of the input voltage on capacitor Cl, and read the...
The circuit"s frequency oscillation is /=2.8/ [Cix(/i + i2)]· Using the values shown, the...
A very interesting horn driver project presented by Microchip technology is presented in this...
Servos became valuable products for any variety of plans, like robotics, automation or only...
It has to placed making an angle of about 30 - 45 degrees to the ground. This makes the rain...
It started out as a simple unenclosed variac (variable autotransformer) and electrical outlet...
This is a combination digital clock timer and solar panel charge controller used to maintain a...
This is one of the original brand-name folders created for the site, and for almost three years...
The GS1674 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals...
The DZ-2 was built by RCA, Camden NJ, for the U. S. Navy for use in naval aircraft as a Radio...
An 8-bit password is the input to this system. The password entered by the user is compared with...
Is a good touch-down can delay the lamp, the circuit is characterized by: the static power...
Fade-in fade-out light switch can turn on and off when the lamp brightness changes slowly, and...
