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.....

Tired of always spending money on flashlight batteries only to have them fail just when you need...
The Saver V5.0 runs simple clock emulation program, turns a night light on and off with preset...
Choosing de rather than ac coupling can reduce much of the noise associated with preamplifiers...
The battery life and operating cost of an electric vehicle is severely affected by overdischarge...
The HllC supplies the de latching relay function and reverse polarity blocking, for currents up...
Transistor Q1 acts as an amplifier for condenser microphone MIC1. The output of Q1 is applied to...
The transmitter for the wireless headphones is built around a CD4046 CMOS phase-locked loop,...
This is the very simple circuit diagram of 150W power amplifier. The circuit is easy enough to...
This simple FM (frequency modulation) transmitter is powered only by a 1. 5V battery and uses...
This circuit employs a synchronous demodulator to separate a 1 KHz signal from noise and measures...
In this auto shut off tone generator project, once the switch to the 9V power supply is...
As we activate to adore those apathetic bleared canicule of summer, the best important affair on...
By using a relay, you shorten the distance that you must pull the thick wires (especially through...
The Nutchip decodes the signal, differentiating between immediate and delayed sensors (aside from...
Chaolitong Phone Travel Charger for Motorola to 308,328,338 and 368 series mobile phone battery....
