We love LEGOs and while we’re partial to the Mindstorms set, Anders Søborg has built and programmed his own NXT scanner comprised mostly of these bricks. For those not familiar with NXT scanners, they’re a “standalone” scanner that can scan and save images as BMP-files. The images scanned can be saved in either 24-bit true color, 8-bit color or gray scale.
Although the device isn’t faster than any other scanner on the market (it’s quite slow actually), cut it some slack: it’s made out of toy blocks. Anders was also nice enough to include DIY instructions on making your own, complete with programming instructions and all, on his website.
