Joule Thief Index Card with SMD LEDs

I was issued a pseudo-challenge to see if I could solder super-tiny 0402 (0.4mm x 0.2mm) SMD LEDs.  They are about the size of a speck of dust and pretty easy to lose even sitting right in front of you.  You need super-fine tweezers to even pick these up, but don't apply too much pressure and the LED may go flying, never to be seen again.

I was able to get not one but two LEDs soldered to strips of copper tape placed very closely together with gobs on solder on them.  To illuminate the LEDs, I decided to build a joule thief on the index card with all the components super-glued to the card.  It works really well, actually.  I labeled the parts on the card.  Now it's my joule thief reference card!
