Hi everybody,
I found this **broken link removed**
Have a look at the Novex schematic. It looks very easy to implement. Only the software part is missing.
What do you think?
Thanks
P.S. I know it's a bit outdated but for some custom software project it could save you money...
It is a circuit that goes inline with an old centronics parallel port and still passes data thru. Those are sort of ports are going away on computers now. I guess the idea is to put code it in to make a security gongle or something?
As you say, it's getting to the stage that computers don't have parallel ports anymore, and people have always hated dongles as well - so it doesn't seem a very interesting project?.
Parallel port Dongles were usually easy to crack too. Autocad & Oracad used them but cracks and "patches" were close behind. I've never seen uncrackable software protection.
When did you last see a program that used a dongle?, there's never been any suggestion that it's for any illegal purpose - or that it's in any way a replacement for a commercial dongle.
Guy might be tring to protect his code with a dongle (right).. No matter, laptops and new high end machines have no serial or parallel.. Of course I do not have one of the high end machines so I can buy his code/dongle.
If he is tring to crack a gongle, that is the wrong way for sure (doing it in hardware he has a "snowballs chance" he can get the code from the working one).
