Join the biggest Electronics Community Shannon Fano Elias encoding algorithm is a precursor to arithmetic coding in which probabilities are used to… Imagine a distributed cloud spread all over your campus. The main server is sitting somewhere on the… Audio frequencies range from 20Hz to 20kHz but these frequencies are …

Presented here is the circuit that drives twenty LEDs in a random manner. LED flashers and sequencers are used in decorative lights to give pretty colour combinations by glowing LEDs in random or sequential manner. This flasher has a chip that controls the random flashing rate of the LEDs. Circuit …

Air-coolers provide cool air in a room by adding moisture to the air. This moist air is blown inside the room by an exhaust fan or blower, which makes the room temperature drop. These coolers require frequent refilling of water. Presented here is a circuit to refill water automatically in …

Insulated metal substrates take care of heat dissipation created by modern printed circuit designs. Light emitting diodes (LEDs) have been around for years. Nowadays, these are a major source of light. Unlike filament lamps, incandescent lamps, fluorescent tubelights or compact fluorescent lamps, LEDs consume less power and have a prolonged …

Raspberry Pi is a low-cost, high-performance, credit-card-sized computer for learning, solving problems and having fun. Easy to get started with, this tiny yet powerful computer comes with additional resources including monitor screen, keyboard and mouse. Imagine the inconvenience of moving around the accessories between workplaces for accessing this tiny computer. …

Modern society requires much more outdoor lighting for a variety of needs, but the International Dark-Sky Association (IDA) advocates that any required lighting be used wisely to minimize the harmful effects of light pollution. If you’re looking for dark-sky–friendly lighting ideas and rules, see https://darksky.org/lighting/lighting-basics/. A lot has been published …

Shannon Fano Elias encoding algorithm is a precursor to arithmetic coding in which probabilities are used to determine code words. It is a lossless coding scheme used in digital communication. Probability theory has played an important role in electronics communication systems. It is because information in a signal is usually …

Washbasin Mirror Light Controller This controller circuit based on an infrared (IR) object sensor (Sharp 2Y0A21) is used for saving power of the mirror light near a washbasin. The circuit contains manual on and off switches and an additional automatic switching system. Circuit and working of Washbasin Mirror Light Controller The …

This robot with a camera is placed in a remote location to capture the environment in visual form using Raspberry Pi (RPi). The captured visuals are displayed on the user’s virtual reality (VR) headset. An added feature allows the camera to move in the direction of the user’s head movements. …

This project demonstrates how a simple and fast pulse width modulator (PWM) generator can be implemented using Verilog programming. It is simulated using ModelSim, a multi-language (hardware description language) simulation environment from Mentor Graphics and tested on Basys 2 FPGA development board from Digilent. PWM generation Block diagram of the …
