Very easy. I used a yellow led cause I didn't have a red led, but it's the same.
<p>Very easy to make, and it works! I used hot glue and heat shrink to make a case for it. Thanks for posting this!</p>
There will be no activity on &quot;D-&quot; using this tester , You need some type of communication to get &quot;D-&quot; activity.
hi there the D- dont plug on GND?? why?
Just made one of these, given to a friend to test further. pretty cool and simple. Thanks.
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.
have to try this one.
