Technical Stuff
angel on Nov-10-2009
Have you guys seen those barcode scanners at the groceries and department stores? Ever wondered how they work? Apparently, these electronic devices scans barcodes in products using a light source, a lens and a light sensor. This is responsible for translating optical impulses into electrical ones. I’m not really a techie and I’m not well versed in technical stuff, but I am fascinated with how things work. I sometimes try to dismantle stuff in my head and try to figure out how they work. Sometimes I also look up the most interesting stuff in the Net just to have some kind of idea how they work. Aren’t we all glad there are brilliant inventors in the world? They certainly make things a lot easier for all of us.
that was cool. nice thing that I stumbled upon this one. will come back for other articles. thanks!
