I'm going to use a plastic phone card for this guide.  Make the holes for Data bigger than the ones for Clock, as an example you can use a 5mm hole for Data and a 3mm hole for Clock.  Put Data's hole slightly before than Clock's hole, this is very important.

If the reading circuit detects the Clock's hole before Data's hole you'll have a "0" and not a "1" as it's supposed to be. If you make Data's hole a little bit bigger and slightly before than Clock's hole, you ensure that the first thing the reading circuit will detect is Data.  This will be "1" and then the Clock's hole, getting a "1". Of course the holes have to be at the same distance as the PTs distance between each other.

   Here you can take a look at my card.  The holes on the right are the Clock holes, the center of the card isn't perforated since I've used that part for Reset.  On the left side, the big long hole is Data, I did it like that because I was lazy and I didn't want to make hole by hole, as you can imagine Data was always "1".

   And here is the final result, the LED shows when it is disabled and enabled:

   I'm sure you will have questions about this guide, please feel free to post them in the forums.
