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 is a low power voltmeter circuit that can be used with alternative energy systems that run...
It is important to know that transistors Q1,Q2,Q3 must not work like an astable (tri-phase)...
Here's a circuit to create a buzzcoil using a standard automotive ignition coil. A 556 dual timer...
The super LED flasher is actually two complete LED flasher circuits on one circuit board. The...
The tester consists of a rectifier circuit and a multivibrator circuit. The ac voltage is...
This circuit uses a VFO operating from 15 to 18 MHz (Ul), which feeds a balanced mixer (U2). A...
This tremolo effect circuit uses the XR2206 and the TCA730 IC which is designed as an electronic...
Here is a simple circuit that can be used to check the sound levels. The sound pressure meter is...
When controlling motors with a microcontroller (like shown), the snubber is really pretty...
To activate the air muscle, valve labeled #2 is opened. This causes the air muscle to contract....
Magnetic stimulation is a non-invasive method of stimulating the brain and peripheral nervous...
A stereo valve phono pre built for me by a techie mate. He has the power transformer and all...
Circuit as shown by the two and four decimal counter CD4017 password switch composed by the...
Both transistors are low noise types. In the original circuit, I used BC650C which is an ultra...
