The input signal drives ICD. Because ICD"s positive input (V+) is slightly offset to + 0.1 V, its steady state .. -
The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in responding. Converting....

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 Tab antenna is a folded monopole that you miniaturize by forming it into an inverted L with a...
It's a great convenience that most modern cars come with a built in alarm, however it is nothing...
The monostable period is set for about 1 second, as is the usual case. The induced line hum comes...
As explained elsewhere in this article set, after an equipment failure I decided to replace a...
This is a grid dip oscillator (GDO) circuit developed by Luigi Falcone. This circuit uses seven...
Every driver knows that a high intensity light striking one`s eyes can have dangerous...
It uses very common building blocks. The high voltage power supply is a classical oscillator...
Below is the circuit I`m working with; I plan on having the infrared phototransistor pairs...
The charger can charge a single cell or a number of series-connected cells up to a maximum of...
Using Nokia 2300 for my project and the original earphones that came with it. They work properly...
This 40W fluorescent lamp inverter allows you to run 40W fluorescent tubes from any 12V source...
One of the most interesting shield that you can mount on the Arduino platform is certainly the...
As shown in FIG integrator drift is very small, at a temperature of -55 C ~ + does not exceed...
