Introduction
GIMP is a free/libre and open-source image manipulation software which can is used to edit and modify images. It is also cross-platform which means it is available for multiple operating systems. In this article, we will look at a very handy feature this application which can help us approximate the dimension of an object using a reference scale. In other words, it allows us to approximate the dimension of the target object relative to an object of known dimension.
The motivation f…
Building a Microscope using a Webcam
You do not need to know any electronics to do this project
A microscope magnifies small objects to explore the beautiful world of microorganisms or anything that cannot be seen by our naked eyes. It will make us realize that a big world exists even in a drop of pond water.
So, can we build a microscope ourselves?
Yes! Of-course you can build your own microscope, using which you can also take pictures and videos.
The picture shown below is one of the very lo…
Lights, Camera, Action: How to convert your Smartphone into MicroScope for less than a $1?
Webinar Link at 3:30 pm on Thursday, Nov 19.
Do you know, you can attach a lens from a low-cost laser pointer or non-functional CD-DVD player and upgrade your smartphone into a digital microscope?
The idea is inspired from many such attempts by community members to design a simple setup to convert your smartphone into the microscope ( see design by Yoshinok and recently by Singh, M. and Kiran ). Even pap…
