Diffuse an LED

For a recent project I am planning to do, I needed to diffuse some LEDs. I tested out two ways of diffusing LEDs.

Sanding with a sand paper
Diffusing with correction ink (liquid paper)

Sanding takes time, correction ink is a bit too thick. So I diluted the correction ink with acetone (I think — I actually bought cheap nail polish remover). The results are here for you to see. Let me know what you think of the two methods.

In all of the images, the left LED is diffused with correction ink (liquid paper), the center one by sanding, and the right one is a regular LED.

This gives you a comparison of diffusing an LED with sandpaper vs liquid paper.

For a good, step by step instruction on how to diffuse an LED with a sand paper, see how to diffuse an LED on instructables.com.

A Good Computer Science Engineer

What makes a Computer Science Engineer? Or a Computer Scientist?

Language independent Computer Science Engineer. A computer language and compiler are tools for development of a solution. The aim should be to choose the right tool for the right job, and not fit the language you know into the solution. By doing this, enormous efforts may be saved and the output will be clearly visible in the quality and performance of the software that is being written.

My motto as a professional is to concentrate on the computing aspect of the problem rather than to just get the job done somehow. This is the key to writing good software.

A good engineer is neither one who sticks to pure theoretical aspects of computing nor one who “gets things done” somehow, but is one who identifies the part of theory that needs to go into practise for the problem in hand, and implements the same. I try to be one of those people.
