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.....

Below is a rough schematic of the layout of the accelerometer PC board looking from the component...
a year ago I designed a class-D amplifier based on the TAS5162, pcm1808 and TAS5086. During the...
This is a simple form circuit for a 2-station intercom using common 8R mini speakers. The...
This simple circuit and program listing allows the Maximite microcomputer (SILICON CHIP,...
The afterward account shows the electrical base affiliation diagram for Honda Motorcycle CB750F....
The brief with this project was to produce cost effective electronics that could be assembled by...
The circuit diagram shows a powerful stereo amplifier which can deliver a power of 22W. It is...
Quiz-type game shows are increasingly becoming popular on television these days. In such games,...
I designed a 8x8-bit memory module using LogicSim, a shareware software program that allows...
O The SA1021 integrated Radio receiver circuit is for portable Radios stereo as well as mono,...
This is a design project of an air-filter sensor to be used in home heating and cooling system....
The Current Sensor Board contains an Atmel AVR AT90S8535 running at 8MHz which samples six ADC...
Adder circuit commonly used inverting input, namely the inverting adder circuit. It was to the...
As shown in FIG, AD7520 is a CMOS type integrated circuit DAC over 10 channel, may be provided...
Circuit shown in Figure 3-136. The line adds a limit switch SQ, when the motor is running with a...
