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.....

Each of these ways have their own advantages and disadvantages. The multiple transformer way is...
Put the car in reverse and the circuit provides a loud, audible beep at the rate of about one per...
A single op amp, one fourth of an LM324 quad op amp, is configured as a standard inverting...
Nowadays, USBis the most popular connection connection between PC and peripherals such as AVR...
LM4880 is HiFi dual audio amplifier IC from National Semiconductors. This IC is specifically...
Included on this page are various small circuits I have created over time. Some are trivial, some...
183. 6MHz SAW filter in a CDMA application. The SAW filter S-parameter is used to simulate the...
This circuit is a toy to encourage young children to count. Power is turned on by switch S1, then...
Multi Tone Alarm Description This is a simple and easy to build multi tone alarm circuit that can...
schematic of board with PIC16F84 and also other PICs which can be connected to this USB PICKit2...
This is a good Electrical project report on Infrared Remote Control On/Off Switch and was...
This 40W fluorescent lamp inverter allows you to run 40W fluorescent tubes from any 12V source...
100 MHz frequency and period counter using the Intersil ICM7226B 40-pin DIP. This circuit uses a...
