[Boris] wanted to help ease his sister’s seasonal affective disorder. The most common way to do it is with fairly expensive light boxes. [Boris] built one of his own instead.  Now his sister can blast her sadness away with over 10,000 lumens of CFL happiness.  This is pretty much the same method one would use to create a ring light for photography.

This amazing looking set up is for photographing insects in flight. While this is similar to a past project we covered, this one seems to have several improvements. There are no longer any arms that you have to position on either side of the insect. This system uses an additional lens, picture at the top, to detect the reflected laser light off of an insect.  Requiring only 40 microseconds to determine if the insect is in focus, capturing a flying wasp shouldn’t be too hard. You can see four lasers in the pictures, two are IR and used for focus, the other two are simply to help the operator target their bugs.
