Design of Solar Power LED Lighting System using Horizontal Two-Axis Arduino B...
Design of Solar Power LED Lighting System using Horizontal Two-Axis Arduino B...Associate Professor in VSB Coimbatore
The project deals with design of solar power LED lighting system using Horizontal
Two-Axis Arduino based Solar Tracking System. The main goal of this project is to design
a very precise solar tracker. The project is divided into two parts; hardware and
software. Hardware part generally composed of solar panel, two-DC motors with
gearbox, LDR sensor module and electronic circuit. Software part represents the thinking
behavior of the system, that is how the system acting under several weather conditions. In
this work sensing of the sun position carried out in two stages primary and secondary.
Primary stage or indirect sensing performed via sun-earth relationship as a coarse
adjustment and second stage or direct sensing performed via set of LDR sensors as output
tuning to trims the azimuth and altitude angles. If the weather is cloudy or dusty, the
tracking system uses primary stage or sun-earth geometrical relationships only to identify
the location of the sun; so the system tracks the position of the sun regardless the weather
condition. The energy extracted from photovoltaic (PV) or any solar collector depends on
solar irradiance. For maximum extraction of energy from the sun, the solar collector
panel should always be normal to the incident radiation Solar trackers moves the solar
collector to follow the sun path and keeps the orientation of the solar collector at an
optimal tilt angle. Solar tracking system improves substantially the energy efficiency of
photovoltaic (PV) panel. In this paper, an automatic dual axis solar tracking system is
designed and developed using Light Dependent Resistor (LDR) and DC motors on a
mechanical structure with gear arrangement. Two axis solar tracking (azimuth angle as
well as altitude angle) is implemented through Arduino UNO controller based on Sun
Earth Geometry. The results indicated that the automatic solar tracking system is more
reliable and efficient than fixed one.Principles of wind turbines
This document provides an overview of wind turbines, including:
1. Wind turbines convert kinetic energy from wind into mechanical power via rotating blades and a shaft, which then generates electricity through a generator. Multiple wind turbines comprise a wind farm connected to electrical networks.
2. Common wind turbines have horizontal shafts, and are designed for wind speeds between 5-18 m/s at heights of 50-200 meters. Design power ranges from 2-5 MW.
3. Leading countries for wind power production are China, USA, Germany, Spain, UK, France, Italy, Sweden, Denmark, and Netherlands.
Foot step power generation system
This document describes a footstep power generation system that uses piezoelectric crystals and a motorized mechanism to generate electricity from footstep power. It uses a PIC18F452 microcontroller as the brain to interface with transmitters, receivers, sensors, and an LCD display. The system measures voltage, current, and power and displays the results on the LCD. A boost converter with closed-loop feedback is also included in the schematic. The goal is to produce electricity using natural and free resources.

This document provides an overview of DC microgrids and distribution systems. It discusses the motivation for reconsidering DC systems due to the rise of DC loads from renewable energy sources, data centers, electric vehicles, and others. It also covers the feasibility and design of DC distribution systems, including protections, standards, and existing DC systems used in data centers, telecommunications, and ships. The document concludes that DC distribution provides advantages over AC systems, with only two conductors required and no issues of inductance, capacitance, skin effect, or synchronization.
Solar Tracker
This document describes the design of a solar tracking system using an 8051 microcontroller that automatically orients a solar panel to track the sun from east to west for maximum solar energy collection. The system uses a light dependent resistor to sense light intensity and signal a stepper motor controlled by the microcontroller to rotate the panel. It provides an affordable way to maximize solar panel efficiency through software algorithms that precisely position the panel without needing many sensors.
Solar tracker
This document describes a dual axis solar tracker. It tracks the sun along two axes (east-west and north-south) using light sensors and motors to orient solar panels towards the sun. This increases the solar panel output by approximately 40% compared to fixed panels. The dual axis tracker uses light detectors, a comparator circuit, an H-bridge motor driver, and motors in the x and y axes to precisely position the solar panels. It allows for more effective capture of solar energy throughout the day.
Sustainability and bit-rot
Presentation at the JStor Workshop in Bangalore, December 10, 2010, on sustainability and bit-rot in file formats and software for websites.
The medium without the message (April 2008)
The document discusses different forms of online communication and their properties. It covers ephemeral communication methods like instant messaging and voice chat that disappear when closed compared to more permanent methods like blogs, mailing lists, and websites. It describes key aspects of blogs like reverse chronological posting, archives organized by date and category, and permalinks. Blogs also allow for feedback through comments. The document contrasts mass production and consumption with individual calibration and validation online. It examines speech as private, public or secret and how distribution is shaped by technology, culture and business factors.

Wireless power transmission ppt by P.Sree Harsha
Wireless power transmission involves transmitting energy from one place to another using electromagnetic waves, as an alternative to wired energy transfer which is commonly used but results in significant energy losses during transmission. Nikola Tesla was a pioneer in wireless power transmission in the late 1890s, successfully transmitting energy over long distances using induction techniques. While his vision of a wireless global power transmission system was not realized due to lack of funds, research in this area has continued and near-field and far-field wireless power transmission techniques are now being developed and applied over short and long distances.
wireless power transmission
Wireless power transmission was pioneered by Nikola Tesla in the late 1880s using induction techniques. Wireless power can transmit energy without wires by using near-field techniques like inductive coupling or far-field techniques like microwave power transmission. Near-field techniques work over short distances and include inductive coupling, resonant inductive coupling, and air ionization. Far-field techniques can transmit power over longer distances using directed beams of microwaves or lasers. Wireless power holds advantages over wired systems like no wires or cables needed, but also faces challenges of safety, efficiency, and power losses over long distances.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Crafting Excellence: A Comprehensive Guide to iOS Mobile App Development Serv...

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
