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 circuit, which was developed to monitor the traffic of bumblebees in and out of the hive,...
If you are busy and cannot answer or do not wish to answer your phone, this circuit will give a...
This is a simple triangle-wave generator using two IC devices and a transistor. The triangle...
A 4017 decade counter/divider driven from a low-frequency oscillator (Ul-a and Ul-b) is used to...
Did you check if you actually see the zero crossings on your input pin You might want to write a...
Attach a 12V fan to this circuit which draws 70mA (0. 007A), so the circuit must have at least...
In this auto shut off tone generator project, once the switch to the 9V power supply is...
Because of energy crisis Load shedding may be a common problem in several countries. Sudden power...
FM transmitter circuit very stable and simple given here. With an adaptive antenna, the...
The design changes were primarily chosen to improve weight of the system. The majority of weight...
Tuned circuits consist of C4, L1, C8, L3, and the two 15 pF trimmer capacitors across the...
This is a very simple circuit where the PIC and an internal 1kHz sinewave table do all the hard...
Permits monitoring local VHF FM repeater for calls from friends without having to listen to...
The two input boards ( ADCV or digital ) get connected to AD_CTL1, AD_DATA1, AD_SUP5V_1,...
The figure shows that input from the varistor overvoltage protection role. VDi - VD4 rectifier,...
Application circuit works the device as shown below. For cooling electrical equipment, usually...
Crossing various sawtooth voltage generator, the common denominator is the use of a capacitor...
