PWM with ATMEGA 32

PWM - Pulse Width Modulation.

The basics about PWM can be read here

Why PWM??
Suppose you have a motor with a certain torque and RPM, and you want to change the RPM. This can be done easily by reducing the voltage supplied, but due to this even the torque of the motor reduces. So, how to control the RPM of the motor without compromising on torque ???
The answer is PWM - Pulse Width Modulation

HK-922MG Digital Metal Gear Servo

Recently bought this HK-922MG Digital Metal Gear Servo

What i like about the servo are

Processing - Open Source Programming language

Accidentally came across this new language Processing (weird name), mainly based on graphics programming and really simple to use. Processing is built by the electronic arts and the visual design communities with the purpose of teaching computer programming in the visual context. Though built on the Java platform the syntax is drastically simplified.

Here are some images of a snowflake fractal made using processing

OpenFOAM - BASICS

             CFD - Computational Fluid Dynamics is a branch of fluid mechanics that uses numerical methods to solve and analyze problems related to fluid flows. More information on CFD can be found on the Wikipedia page. There are many CFD software available in the market but OpenFOAM is an open source CFD toolbox so it is free of cost and also provides accurate results on par with many of the commercial CFD software.

Fractal Gallery

Fractals are typically self-similar patterns or self-replicating images, where self-similar means they are "the same from near as from far". Here are some Fractals made by me i'll post the C code in another post in which i'll give a detailed explanation.

My First Coro Built R/C plane

Since a long time i've been gathering information to design a R/C aircraft and yeah after a lot of effort its ready. For beginners it is better for an ARF or RTF version to begin with because if u don't know to fly even if you build a aircraft with good flying characteristics you are going to crash it some how and start building all again. Generally people lose their interest in the hobby due to this, as they work hard to complete the model an at last just goes into the bin, using simulators is an other option but flying in simulators is far different from flying a real R/C aircraft.

Hi and welcome to Timepass Backwas, a blog in which i decided to post my small projects that i do in college and free time.

The content might be mostly related to R/C stuff, Robotics, AVR programming, Matlab/Scilab programming ....

Please be patient while reading this blog and if any mistake please feel free to comment.
Hope you'll enjoy reading this blog.
