Hello! That was an extreme case. The people behind the hack got lucky. The people behind the victim were clearly at fault, and didn't have the intelligence to eventually upgrade their methods. The people commenting showed their usual lack of attention to details. Especially since not one of them is as familiar with the One-Wire technology as we are. (And that includes anyone from Maxim who is actually here today.) My local grocer recently added four self check machines to their normal layout. A series of timed iButtons are used to sequence who's minding them. My bank may still be using them to allow the bank officers access into the ATM workspace for loading money boxes, and removing deposit items. And of course a lot of us must be doing what Pat suggested. I did try and build an arrangement using two thermal sensors and one RTC iButton. The arrangement worked, but the fact that a typical NYC apartment where I get my heat as part of my rental payment was confusing the sensors and annoyed the RTC iButton. I've got something taking shape, but I don't know how much of it is still doable........ ----- Gregg C Levine [email protected] "This signature fought the Time Wars, time and again." ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
