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.....

Its a very easy interface to build an requires only a few £/$ worth of components. A you can see...
The circuit has both square-wave and triangle-wave output. The left section is similar in...
As the speed of an electric drill is decreased by loading, its torque also drops. A compensating...
The ADC Tester (A2100) is a LWDAQ device that records the output and power consumption of two ADC...
As you see in the circuit above the four pins "Controller pin 1", 2, 3 and 4 will control the...
This is a circuit for an electrically operated rolling shutter usually has a standard control...
This circuit is one of the simplest voltage to current converters to drive low loads. In this...
This is a simple circuit in which the glowing LED can be switched OFF just by a puff. A condenser...
The simple relay adder was built using free NOS relays sometime in 2005, but my goal was to...
TIP141 si a npn silicon power darlingtons designed for complementary use with TIP145, TIP146 and...
The standard Class AB audio power amplifier allows for direct coupling of the output of the...
Built around an Intersil 7216 frequency-counter IC, this counter has a basic range of 10 MHz, a...
