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 project Digital gated Emulator using Microcontroller is used to emulate the basic gates such...
If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully functional...
without significant added complexity, and a natural tendency to run away under no-load (high Q)...
The second gate (G2) of a MOSFET can be used to incorporate a crystal oscillator into the same...
This converter has a central component, the CMOS 4047, and converts a 12V DC voltage to 220V AC...
The Proximity Camera Head (A2047) is a Long-Wire Data Acquisition ( LWDAQ ) Device that reads out...
Front and rear fog lamp schematic of Daewoo Korando shown in the following figure. It shows the...
This page features a circuit that has twenty open collector outputs that turn on one at a time in...
The metal detector circuit is shown here that the limits represent the sake of simplicity for a...
This article explains What is inverter And how can you construct your own simple low cost 12V to...
A good quality preamp tone controls, a total of three circuits. We choose to use the NE5532 is...
With the preset at its max. the flashing rate of the LED is about 1/2 a second. It can be...
The solar panels are operating at optimal parameters when they are at the perfect right angle to...
