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.....

Any good power transistor can be used in this circuit. The base resistor should be adjusted to...
IRF9540N Gate Charge Test Circuitis schemed in the diagram below. IRF9540N is known to be...
This circuit is used to sense the insertion of a penny. Before the penny is inserted, current is...
This circuit is one of the simplest voltage to current converters to drive low loads. In this...
The pressure sensor (MPX4100)MPX4100 is a pressure sensor that is equipped withsignal...
As I was developing my IR Extender Circuit, I needed to find a way of measuring the relative...
The following circuit shows about Schematic Diagram Of LED Sequencer. This circuit based on the...
This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is...
the rest of the pictures show the construction of the sub. It was made out of two C channels...
Measure voltage across the 1k resistor connected to the input stage and Vcc. The DC voltage...
The SciSys Leonardo and Saitek Galileo and Renaissance chess computers could be connected to a PC...
Circuit work process is: When the momentary switch S between, since the voltage across the...
