Homemade Bokode

We’ve recently been getting a lot of new comments on our Bokode post from a while back, and with good reason.  [M@] has managed to find a way to replicate Bokode at home, using $0 worth of equipment (before the price of microprint). To accomplish Bokode at home, it seems all you need is and old webcam lens assembly and an LED.  Of course the his version is not as thin as a regular barcode so it probably wont be replacing anything in the near future, but the concept of from MIT to home within such a short period of time is amazing.

Bokode, a new barcode


The MIT Camera Culture Group utilized Bokeh, an effect where the lens is purposely placed out of focus, in order to vastly improve current 2D barcode technology. Dubbed Bokode, the team claims that an off the shelf camera can read data 2.5 microns from a distance of over 4 meters, compared to today’s average barcode reader’s maximum distance of only a foot or so. What looks most interesting is the ability to produce a smoother and more accurate distance and angle calculations (relative to the camera): allowing for a better augmented reality. It also seems to be more secure than traditional 2D barcodes, that is of course until the hacker community gets a hold of it.
