Reply to "Design of a $10-20 DCS-TIU Port Tester Tool?"

Sit tight for a few days, the landscape is changing. I like the self-powered idea, glad Stan thought of that. I don't see how it should affect the DCS signal in any way, and it really simplifies the usage of the tester. I'm still looking at it an making "tweaks". For one, it occurred to me that the .5" spacing for a 1/4w resistor was generous, they fit just fine in .4" spacing, so I adjusted the layout to accommodate them. This makes it easier to fit stuff on.

Here's a shot of what I have right now, the LED's are now 3mm units, and the resistors and diodes are all .4" spacing. It's not quite so crowded now, though the board is getting full. Thru-hole stuff takes a lot more real estate than surface mount, this would be on a board half this size or less.

I kept the board at the same size as before so far.
