In the spirit of Earth Day, I have created a revolutionary new energy-saving lighting solution that is only ever on when your eyes are open. This is remarkably more efficient than normal lighting that remains on, even when your eyes are shut. Using my device, you get light when you need it, and darkness when you …
One of my clocks stopped working – and it happened to be a clock my wife likes a lot. Went to the repair shop and the guy said that he didn’t have the spare parts and could not repair this. So – I thought – why not build an LED clock – I had tons …
Ever since my addressable RGB LED strips (WS2812B) came from Aliexpress, I’ve been fascinated with LED projects. Following up on my success with my Charlieplexed LED clock, I wanted to create something with more Jazz.. While browsing google images, I came across an instructable for an Arduino Infinity Mirror and the brain cells started working in overdrive. Why …
Auto Intensity Control Of Street Light Using Arduino In this project, I am going to show you how to control the intensity of LED lights according to the time and the light intensity of outer atmosphere. This is an amazing and very useful project because it prevents the wastage of electricity. This project automatically turns …

The 3rd harmonic distortion meter has been designed for measuring the quality of AC supply. The meter is built with a PIC18F2550 project board and the full wave rectifier front-end circuit. The AC power line, 220VAC is measured through the step down isolation transformer. The input signal to the 10-bit ADC is full wave rectified. The software …
I recently bought The Energy Detective (TED), a pretty inexpensive and friendly way to keep tabs on your whole house’s electricity usage. It’s a lot like having a more featureful version of your utility company’s power meter, sitting on your kitchen counter. It can estimate your utility bill, and tell you how much electricity and money you’re …

Low-power microcontrollers have done much to improve longevity in energy-harvesting systems. Clever architectures and use of low-power modes lets micros draw nano amperes of current while preserving registers and configuration data. This allows designers to use smaller and less dense energy storage solutions that were not feasible in the past. Nevertheless, energy storage, which plays …

A tyre pressure monitoring system (TPMS) aims to monitor air pressure on various automotive systems. The most common TPMS sensors mainly use sub-GHz radio standards to transfer information to the vehicle’s computer. There are two different types: direct (dTPMS) and indirect (iTPMS). The use of blue tooth low energy (BLE) connectivity makes it possible offering …

Bismuth is considered as a “green-element” and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb) on the periodic table, can be used to make inexpensive solar …

Researchers developed a multi junction solar cell on a GaSb substrate that can efficiently convert the long-wavelength photons typically lost in a multi junction solar cell into electricity. This prototype cell has an efficiency of 44.5% which is higher than conventional solar cells. A GaAs-based cell is stacked mechanically with the GaSb-based materials to create …
