Very easy. I used a yellow led cause I didn't have a red led, but it's the same.

Very easy to make, and it works! I used hot glue and heat shrink to make a case for it. Thanks for posting this!

There will be no activity on "D-" using this tester , You need some type of communication to get "D-" activity.

This works pretty good, I threw it in a project box since i didnt have breadboard but i like it, easier than the one that uses the etched circuit board.
