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 DC output at Pin 1 vanes linearly with the RMS input at Pin 4. 2 CT is tweaked until the svnc...
This circuit allows the effective power in a load to be controlled by varying the duty cycle of...
An LM311 comparator converts a small analog signal to a digital level for the DC4046...
Here`s a circuit of 7 Watt audio amplifier that is very simple and very easy to build. This...
This is an amplifier circuit using ic LM12 as the main amplifier. This amplifier has a 150Watt...
A DIY intervalometer for my Sony NEX 5N camera so that I could do time-lapse photography. This...
A little lightweight MFJ-4225MV power supply. It puts out about 25 A, maybe 20 continuous, which...
Analog to Digital converter modules are used in Micro controller based projects where the analog...
It is impossible to imagine present day society without any batteries. Count the number of...
A simple home project can turn catastrophic fast if you come up against an electric cable, gas...
You need a TSOP4156 which can be a tough one to get or expensive to buy. I had plenty of old...
I managed to break my laptop, by reversing the polarity of a universal power supply. The repair...
A MAX620 connected to form a complete stepper-motor drive. TTL/CMOS signals from the logic...
In the laser tube drive circuit are often provided with a photodiode, which generates a laser...
