This light doubly functions as an odd little look through flashlight. I've used it quite a few times in the network closets already!

Your sample picture is fantastic! I'm in the process of designing a ring flash for macro shots, and this gave me some solid ideas.
This is going to be a present a friend and jewelry maker, I often hear about lighting struggles. He has a really complex setup that takes loads of space.
One possible improvement: put some half translucent paper between the leds and the object, this softens the light. If you don't have this, take regular printing paper and put vegatable oil on it. let it soak up the oil overnight and remove the excess oil.

I also used Elmer's Tack. Its a removable Adhesive putty thats going to replace my hot glue gun. Soooooo much easier to work with. repositionable, sticky, insulates.
Use ledcalculator.net/ takes all of the math out of the equation!! Put in the values for your LEDs and it spits out the needed resistors. I've got my LEDs way undervolted because they were a bit to bright. Maybe the second version I'll add a potentiometer.
LEDs are at 20mm from the deck
Pedestal is 15mm high
