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.....

The output cable from my 20 MHz function/sweep generator dangled over the side of the workbench,...
The circuit has been designed to accommodate all those who dedicate many hours of their lives by...
Most car door switches are simply single-pole switches, with one side grounded. When the door is...
This filter is used to reject or block a frequency or band of frequencies. These filters are...
August, 2007One of my other hobbies is photography, and, about a year ago, I purchased a new...
The circuit claimed has a high movement sensitivity. Even air moving (hot air rising, wind...
A front-end circuit has been developed for the D0 upgrade for reading out visible light photon...
On many cars, the boot light will not go out until the lid is properly closed. It is all too easy...
The Cmos 4060 is a 14-bit binary counter. However - only ten of those bits are connected to...
FM Radio Receiver IC TDA 7012T is very simple, but it has an FM radio receiver sensitivity and...
This circuit interfaces a standard RC-control to a standard PC game port, see figure 1. The main...
When connected to popular Stax Class 1 electrostatic headphones, the design shown in the figures...
1Hz clock signal generator circuit It shows a sophisticated l llz clock signal generating...
Differential amplifier circuit four connection methods and compare the characteristics of a a. O...
