Notes...

(*) 11-6-10 schematic shows 5 resistor packs, easier to wire with 6.
(**) ribbon cables made to order, will show as out of stock.
(***) heatsink gets a bit warm, OK with specified adapter but
      if any chance of higher input voltage, use a bigger heatsink.
(****) data LED's didn't quite fit, might be better to get a bigger/cheaper
       piece of perfboard from the 'shack.

Please double check the part numbers, this was thrown together
quickly (got stuff to do:-), hopefully I typed correctly and didn't
miss anything.
