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.....

A basic Imfra Red Link for audio communication for distances upto 3 metres. Transistors can be...
This is a circuit monitoring device. It runs for over 10 days and can log up to 32k events both...
Most audio amplifier systems must have preamplifiers with many different characteristics. These...
The LED predriver output pulses an external transistor which in turn, switches on the infrared...
Getting microprocessor designs to work is notoriously difficult when both the software and...
IC1 is a dual operational amplifier. In this circuit each op-amp is used simply as a voltage...
Using TCM3105 FSK modem chip from Texas Instruments, you can easily build a Bell 202 or CCITT V23...
The circuit was meant to be powered by a power supply, which is why there is no transformer,...
Frequency range is 100-108 MHz. The circuit is only mono circuit, and accepts an audio input from...
Here is the circuit diagram of an FM transmitter using the IC UPC1651. UPC1651 is a wide band UHF...
A telephone ringer capable of making any mains-powered device work from the ringer of your fixed...
The combination of the LM4651 driver IC and the LM4652 power MOSFET Class D power amplifier IC...
Here`s a Regenerative Receiver project that I designed for the 80 meter Amateur band, but which...
