majzoobiyat hologram

Firstly, thanks to my ex-landlady for handing over her brother's stash of Depeche Mode to this tenant as the parting junk. Bengalis... the most curious ear this side of the planet. Or maybe she was just hinting me something by conveying 'leave in silence'.

I knew there'd come a day when me and Depeche Mode will get to spend quality time. I would get to know them more.

Well, I sorta did, with the latest hobby project, to generate holograms. What went in, was the jewel case of this album, what came about was a tiny plastic box (best to describe it as 'light box') that would serve the purpose. And really, all it took was constructing that tiny box.

I'd first tried it with much thinner plastic, that of a cutout soda bottle, last Caturday. Even though it got a bit mangled, it still served the purpose. I was ecstatic for a little while, then 'rest of the world' took over, and over the next 4 days I couldn't improve upon it. Until today. Today was almost done, but then the Depeche Mode case was found, and things went in another direction. I spent a good hour making the box cutout, from what was a much sturdier plastic than I had handled earlier.

Cutting a jewel case isn't easy, kids. In possession, thankfully, came this set of SK-5 Steel blades, which though didn't seem resilient, proved to stand all torture. Not only did they help make the cutouts for the box, the blade itself didn't get damaged. I later learnt that SK-5 is also used in a lot of knives, and instructional videos show how even repeated stabbing of metal (demonstrated on car doors) won't do a darn to the steel. Apparently, SK5 be so good, that it could be sharpened easy in the field as well be used as a spear without risk of breaking.

(on SK5 Steel) It is the Japanese equivalent of American 1080, a high carbon steel with carbon between 0.75%-0.85% and 0.60%-0.90% manganese. The excess carbide increases abrasion resistance and allows the steel to achieve an ideal balance of very good blade toughness with superior edge holding ability. Due to these characteristics, this grade of steel has been used traditionally for making a variety of hand tools, including chisels and woodcutting saws, and has stood the test of time and use over many years.
Hence I fearlessly proceeded to use my new set of blades on the cover. Easier said than done, really, since the thing took a while, and operation with different blades and grips.

Once the lightbox was done, all needed, were hologram videos. These take an object and project it on the screen in 4 directions, about a pivot point, so that the final composite made by our eyes is a 3d object. The composite is an illusion, really, just a play of light, and that there is no actual object there.
