Re: 19,008 LEDs on the wall, 19,008 LEDs

Just thought I'd give an update:

-I've soldered 13,200+/-10 LEDs so far.
-Of the 16oz of solder I started with only 7.25oz is left.  My food
scale isn't strong enough to weigh the cut off legs.  My friend says he
has a digital one, so I'll try to get that.
-Only 5808 LEDs left.  I have to finish this project by the 28th in
order to save face to a friend I made a bet with.  ;)

Keep pulling for me!  I designed the column drivers.  Looks like that
will be a project too.
Column Driver for 216 characters:
-54 - 74HC04
-27 - 74HC138
-27 - 74HC133
-27 - 74HC244
-432 - 74HC574
-216 - ULN2803
-1728 - 24ohm resistor
-etc

This is one build, thats for sure.  Preliminary calculations are
showing 138.7A draw, 276watts of heat and 416watts of stuff other than
heat.  Should be bright enough.  :)
