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 adaptor will capture plots or prints of your GPIB instrument to your PC through the USB...
This project aimed to develop a wireless system to detect and allow only the authorized persons....
To amplify small current signals such as from ah electron-collector inside a vacuum chamber, it...
With the coupler biased in the linear region by the 10 mA dc bias on the IRED and the voltage...
Although the output is low level and cannot be loaded significantly without harming -accuracy, a...
This circuit makes a very compact level indicator where a meter would be impractical or not...
This page describes the hardware and software design of a printer power switch controlled over...
This touch sensor switch can is designed using inverters (N1, N2)and some common electronic...
Whether it`s truckthrottling over the highway, or an airplane roaring about the sky, or whether...
The diacs, because of their symmetrical bidirectional switching characteristics, are widely used...
The circuits incorporate two FM Demodulator TDA2555 systems to perform the Demodulator functions...
In most of the industrial processes it is required to rotate DC (or AC) motor forward and reverse...
KA2213 is a single chip record and play back integrated circuit which is produced by South...
The light sources for mirror screws based on my work, consist of a dozen or more of high...
Measuring distances using a modulated laser. The circuit I created (see above) is very simple and...
This circuit must be connected before the amplifier circuit. For maximum performance, you may use...
AR-300 DC arc welding machine circuit Rotary DC arc welding machine has AX, AX1, AX3 and AR...
