Come join the SparkFun IRC channel
this afternoon at 4pm. SparkFun CEO Nathan Seidle
will be attending.
About a month ago, we posted
a project from the MIT Camera Culture group called the Bokode
. SparkFun has recently created our very own Bokode that displays a tiny SparkFun flame and even smaller 2D barcodes. The images you see in the video are exactly what our camera sees at varying distances.
In this shot, our camera is only few feet away from our Bokode cube and we were able to resolve a dozen or so barcodes. Each pixel in the barcode is 5 microns wide!
The projected images were printed on a plastic transparency and then mounted at a focal distance away from a lens inside of our plastic Bokode cube.
Here is our Bokode cube. It contains the transparency film, a lens, and a red LED to illuminate the film. All we have to do is power the LED!
