Hi Guys..
Well I don't quite know how to feel.
I am pretty sure I've seen a commercial product made out of a design I gave up for free,
and currently selling on eBay.
I could never be sure, but It's not just the product, but the status LEDs, and what they indicate.
The way I found it was Googling to see if anyone was still making it after so many years!
Don't know whether to be flattered, or pissed that someone is trying to cash in.

It was a project I'd rather not mention now, which was rather simple,
and before I really knew/cared about the details of licensing.

So if you give up a project to the public (goodwill) in this case both hardware and software,
I'd suggest something in docs requiring separate commercial licensing terms!
Cheers, Art.
