TK's panel wiring

[wicked1]

I've got a question for TK.  I was looking at your panel wiring for the din's, and how you have it right on the front panel board.  I notice you have the resistors next to each encoder and button.  What I'm wondering is how you got all those to the ground.  Did you just run a separate ground bus as well as a 5v bus down each row of encoders/buttons?  Maybe since there are a lot of LED's in that area, you needed the ground in that area anyway.

I'm thinking that it is a great idea to just build it right there on the front panel proto board, because I really don't like drilling the hundreds of holes when I print PCB's.

Did you find this was a good solution, or if you did it again, would you use the dout and din PCB's?

thanks!
