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.....

Note first the battery to be treated at the center of the figure. It is connected to contacts of...
The Tiny Audio Amplifier kit is a good choice for battery operation. It is based on LM386 IC....
The FM oscillator/modulator is a voltage-control led oscillator, which exhibits a nearly linear...
The charger"s output voltage is adjustable and regulated, and has an adjustable constant-current...
This circuit uses a CMOS chip and a VMOS FET amplifier for 6 W of audio output. 18 W of audio...
The Liquid Crystal Library allows you to control LCD displays that are compatible with the...
This is a one direction motion sensor circuit. This motion sensor circuit is used to detects an...
This standalone digital thermometer controls the temperature of a device according to its...
In these times with viruses and other threats from the Internet it would be nice to have...
This is the version with 3 6N11 tubes. And as far as I can see identical to the Phenix. It looks...
The setting of delay timing of program will depend on CPU speed. You can use the timing delay on...
The nicety of air coils: one can build them at home rather easily and they seem to swing at a...
Take a V2-400 and use the sub-woofer amplifier for the center channel. Then add a separate...
The Controller Area Network data rate can be from 10kbit/s to 1Mbit/s giving recommended...
