Atmospheric Vortex Engine – Twister Power

Written By: 

Shalem Pravas

Whenever we hear the word “Tornado” we think of destruction and catastrophe. But, to one man it meant, “How can I generate power with that?” It makes sense. Most large scale power generation methods, directly or indirectly involve rotating parts and tornadoes possess a huge amount of rotational kinetic energy. So if we could create a tornado and harness its kinetic energy, it would effectively provide us with a clean source of energy (provided that it is controlled). Generally tornadoes are caused by the presence of a large temperature gradient present in the atmosphere.

The Social Interaction Dress

The wearable technology has been in trend for quite some time, after the solar charged fiber and data registering thread, a social interaction dress has hopped onto the center stage. Though a comparatively smaller hack, this is a commendable development based on Raspberry Pi systems. And the best part, this one can be built by  little efforts from your end. The project was pursued by a Raspberry Pi employee, Clodagh O’Mahony. 
 

How To Reuse The Heat And Water From Your Shower?

Submitted By: 

Shreepanjali Mod
Long relaxing showers sound like fun except for the fact that this leads to a lot of wastage. All the fresh and clean water you use for this purpose actually ends up in the drain along with the heat you used in warming it. However, there is one small hack that can help you in saving this wastage and never again feel guilty after long showers. 
 
Showerloop, is an interesting open source system that recycles the hot water continuously. Created by a team working in Vanta, this one traps the hot water running down the drain, purifies it, and then sends it again for reuse.
 

Motor brightness control using Meditation level and attention level

Contributor: 

Ayush Jain
Now presently in this  article, I am again thinking for changing something depending on my attention level and meditation level, but with more resolution. LED brightness show me a clear picture of variation but the resolution was not so good. I am thinking something which can give us a more clear picture about the variations. How about the speed of a DC motor. We will be controlling speed of a motor using attention and meditation levels of our Brain at any particular time.  We will be using  Arduino UNO , mindflex sensor which we have chooses to read brain wave and a MOTOR to show the results.  We can also use amplifier before the DC motor to see more variations in the speed .
 

How to create semaphore in Linux (Part 23/24)

Written By: 

Ashish Vara
Semaphore is a basic synchronization mechanism and it works as a simple counter which increments on resource allocation and decrements on resource  de-allocation. You can refer to the tutorial Semaphore before learning this tutorial.
 
I will explain how to create counting semaphore in Linux. Counting semaphore is non-negative counter. Semaphore count initializes with a number of free resources. Counter value is incremented when resources are added and decremented when resources are released. In C language, semaphore parameter and functions are defined in <semaphore.h> header file. Various operations on semaphore are performed by different functions which are defined in semaphore header file. You can initialize semaphore, lock and unlock, release the semaphore etc.
 
 

Text animation on 20x4 LCD using AT89C52 Microcontroller

Contributor: 

A M Bhatt
All you might have seen scrolling message display. Matrix LED based scrolling message displays are used widely in advertising, sign boards, information display at public places and many more such applications. Such displays are made up of number of LEDs. There may be single colour (mostly RED) or multi colour LEDs and there are very nice text animation effects like appearing-disappearing text, left-right scrolling, top-bottom scrolling etc. But have you seen such animation effects on text LCD? 
 
It is possible to give such text animation effects on LCD also. In many devices it is required to display different messages or information turn by turn on LCD. 

Arduino Based Wireless Sensor Network

Submitted By:

While completing a coursework on MSc, Peter Haban developed a WSN which he later used for his Arduino controlled greenhouse project. It is an energy efficient network based on the Arduinos and XBee ZNet 2.5 modules. Before proceeding, it’s important to get a brief idea about a Wireless Sensor Network. In this system, there are various spatially distributed autonomous sensors that monitor the environmental conditions like temperature, sound, etc which is passed to the main location. It was primarily developed for the battlefield surveillance but nowadays it is used for various industrial and consumer applications.

PCB Designing using Kicad (Part 3/12)

Written By: 

Venugopal M
KiCad is free software suit for EDA (Electronic design automation), which was created in 1992 by Jean-pierre charras. It has GNU and GPL licenses. I have selected KiCad software to explain PCB tutorials. Since it is open source software, anyone can try this and practice my tutorials.
 
Work-flow:
Before  getting started with KiCad, we must know about some basics and work flow of KiCad. In this tutorial, I am going to explain KiCad work flow, step by step. Please follow the same procedure when working with KiCad.

Wii Nunchunk Pan Tilt Servo: An Arduino Project

Submitted By: 

Neha Rastogi
This article explains about an interesting Arduino project mentioned on the website Arduino Arts. It demonstrates as to how a Wii Nunchuk controller can be used to operate two servos arranged in a pan-tilt assembly. Although there are loads of such projects available over the internet, this one is quite simple to comprehend. So the setup basically requires components like an Arduino Uno, Arduino Prototype shield, Nunchuk I2C connector, 2 servos, 5v power supply (for the servos), servo pan tilt brackets and a Wii Nunchuck controller.
