Then we selected the brightest point in every row of the image and marked it as the laser line. A simple blur, increased contrast and grey scale conversion gave me a very good image of the laser. Using blender I managed to extract frames from the video and ended up with about a thousand frames to work with. Then came a moment of truth and everything was a walk in the park. After digging around a lot I still could not understand exactly how this thing was supposed to work. A little DIY(or jugaad for that matter) and we had a rotating The rotating mechanism was simplicity itself and was simply too easy toД«uild. The camera now sits perfectly on it's own body. After some time I gave up and replaced it with a friend's DSLR. Now to tackle the problem of holding my mobile phone upright. A glass stirrer cut to size( not cut in prototype 1) was nimbly attached to the front of the laser pointer and lo behold we had a laser line. Then I came upon the idea of using a cylindrical lens. This failed miserably as the required RPM was not met. The first method I stumbled upon was to use a rotating mirror placed in front of the point which would cause a circle of laser light. Then came the problem of making a line laser out of a point laser. What I did not realize was that intensity of the laser depended on the current provided and not on the voltage. I bought a laser diode from a friend and quickly burnt. Graciously Anurag helped me with this herculean task.ДЇirst was the problem of the laser. What I had in mind was something awesome, what I obtained was something organic. This burnt all the white flags I may have had and made sure I made my own project.

It was a gutsy move since I knew that if I became committed to this I could not buy this anywhere in the market and would have to build it myself. For my physics project this year I arrived on the conclusion that I needed to make a 3d scanner.
