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 source connection is tapped into the tuning coil low down, as a means of impedance matching...
Room temperature plays a vital role in determining human thermal comfort. This digital...
The circuit's operating principle is that if you make a pulse width proportioal to inductance,...
The circuit is pretty simple. The data lines on the LCD match up well with the data lines of the...
This Arduino-powered vocal effects box pitch shifts and distorts incoming audio signals to...
Wouldn`t be cool sitting at your favorite coffee shop with this phone on the table, and while...
This circuit, a simple mixer circuit. It can mix two signal channels and one channel is output....
An 8 ohm speaker is used both as a microphone and also an output device. The BC109C stage...
Here`s The schematic shown below is a simplest LED flasher circuit. The circuit is using three...
This assemblage was advised for amateurs owning an old accumulating of vinyl recordings and...
As discussed in previous blog posts, pin 5 terminal is voltage control terminal and its function...
A nice schematic for an lm3915 VU meter. I have attempted to create a band pass filter in order...
You can use a Cmos 4001 or a Cmos 4011 in this circuit. They have four - two-input - gates. In...
DF data transmission module operates at 315MHz, the use of surface acoustic wave resonator SAW...
