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 device comprises two parts: LED control board and LED display board. The two PCBs are...
This is the circuit diagram of Line Follower / Line Tracker robot. The circuit taken from the...
The following segment will provide the enhanced Motorola schematic for any typical application...
This circuit LED reproduces the first LED sequence at this time used by FISA on behalf of Formula...
This intelligent electronic lock circuit is built using transistors only. To open this electronic...
Although the voltage across the two pins of our microphone will fluctuate based on the input...
An embedded system which is used for tracking and positioning of any vehicle by using Global...
Here is a simple circuit that can be used as a tachometer. The circuit is basically a frequency...
The STI5211 is a standard definition, full back-end processor for satellite set-top boxes,...
The first timer IC555 creates a negative trigger signal of approximately 45Hz (a trigger impulse...
This is the circuit that sparked off all the other Link Telephone Intercom designs. Originally...
I recently uncovered this schematic, that seems to be authentic and does not feature the 555...
A simple op amp and silicon diode are the heart of the temperature-to-voltage converter that will...
As shown using a cheap CD4060 and 32768Hz crystal to produce highly accurate output 60 pulses per...
