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 hardware block is shown in Figure 1. The MCU is 89Sxx microcontroller. And the complete...
IR radiation from LED2 (modulated by a 1-kHz wave) is keyed by Ul, and Ql is radiated. Reflected...
What`s so special Well, first of all - a very low harmonic distortion. Usually, manufacturers...
What you will be seeing here is a circuit diagram about the electrical wiring diagram of the 1986...
The Amplifier circuit can be made with an IC power amplifier LM1875. IC LM1875 is a single chip...
This circuit features automatic exit and entry delays - an optional instant alarm zone - an...
The circuit diagram shown here is of a simple DC power delay circuit that is based on an SCR....
Electronic devices love accuracy. If you give them the same task twice, you will get the same...
The receiving systems used with the scanning type of echo-ranging equipments are of the...
Capacitor Discharge firing boxes are well suited to certain types of electric match ignition and...
The goal was to convert this radio for operation on the 70cm amateur radio band. This was...
As shown in FIG AC is a dual radio remote control switch circuit. Transmitter: Q3 generates a...
