Video: 2100 Barrel Paintgun

From Wired’s Gadget Lab:

MythBusters Adam Savage and Jamie Hyneman were hired by Nvidia to demonstrate the speed differences between CPU and GPU processing. First, we see the pedestrian “CPU” in the form of a one-pixel-at-a-time paint gun. Painfully slowly, a smiley face trickles onto the canvas. Next, the “GPU”, represented by the truly awesome “2100 massively parallel barrel processors”, a huge paint gun with 2100 barrels spitting paint all at once. The results is a pixelized rendition of the Mona Lisa sprayed onto a wood-reinforced canvas. Total time elapsed? 275 ms. Watch to the very end to see the slow-mo version.

Zoom in to steel.

Also, brass, concrete, tooth, hair, and more…

Project: Build you own spectroscope.

A spectroscope is an instrument used to break light up into its constituent colors, like a prism does, showing the light spectrum.   Why would you want to do this?

A spectroscope is a device that lets us find out what things are made of. It works by taking light and splitting it up into its component colors. Different elements make different colors when they glow. We can make objects and gasses glow by heating them up in a flame, or by passing electricity through them. The spectroscope spreads out the colors of the light, and we can identify the elements by the bright lines we see in the spectroscope. (scitoys.com)

The video above shows you how to make one out of a cardboard tube, an old CD and some card-stock. This page from scitoys also describes a few variations on home made spectroscopes using similar materials found around the house.

Back from vacation....

Hey everyone.  Hope you’re all having a fun summer.  I’m back from my vacation and ready to start posting regularly again! 

Cheers,
