I wouldn't believe it if I hadn't seen it my self.  Hand soldering a 0201.  A miserable young whelp of an Electronics Technician.  Proved me wrong.  Photographic proof submitted to boot:

He did use a microscope.  And a JBC station with a 0.2mm tip.  But still, it can be done.  Misery upon us all who don't have young eyes and steady hands.

I've been thinking about scoring. 

  + 50 points for attempting this project (or being foolish).

  + 10 points for getting one LED to blink (you got the Attiny in correctly and can tell the polarity of an LED).

  + 5 for the 0805 lighting up (Give me a break, it is not much smaller than a 1206).

  + 10 for the 0603 (so you have an unfortunate set of tweezers on hand).

  + 10 for the 0402 (alright, we getting serious up in here).

  + 15 for the 0201 (you got lucky, punk).

  - 5 for using a microscope unless you are over 50.

  - 10 for using a paste and a mask (hey it works, but you cheated).

By this method, my young unfortunate friend scored a 95.

And I have scored an 85 and 90.  Yes, I used a mask, but I need to prove the circuit and code worked, right?

So, to break the record, submit miserable proof of all LEDs blinking, without a mask, and without a microscope, unless you are unfortunate to be over 50 years of age.
