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 handy companion for a digital voltmeter. Its allowed me to do a lot of things I used to...
This is a simple LED flasher using two 2N3904 transistors. Classic astable multivibrator using 2...
Switching diodes are used to fire the neon lamps when negative-peak modulation hits 50. 60, and...
In this circuit, an LM741 op amp drives a Wien-bridge network using two zener diodes as
Here is audiopreamp mic(dinamic). 200-600-ohm output impedance and low noise pre-amplifier for...
Here`s a design circuit for frequency modulator that is completed with tuning circuit. In this...
The Mk II was a second-generation version of the TG X 50. Both were dynamic microphones intended...
I used some schematics from Elliot sound products to help with this circuit. L-In and R-In come...
This pdf file shows the schematic diagram of my home-built circuit to drive the PDR-56 probe. A...
The past experiences was pretty difficult, because the car horns have an inductive charge and it...
Most surviving TR-1s no longer work. Many collectors (such as myself) prefer to keep them in...
The 10A H-Bridge Motor Controller circuit looks simple but there are some key points that you...
The purpose of this page and its sub pages about members of Z80 family (and close relatives) is...
Circuit core device is a dimmer SM7232 specific integrated circuits, which leads to the foot of...
As shown in FIG alarm by a gas-sensitive sensor element QM, buck rectifier and regulator...
