Re: iButton anyone?
Thanks for the response Daniel, but sadly it is exactly 30k. The machine has a readout on the display which gives a warning at 25k and stops functioning at 30k. I'll post again when the 1-Wire usb and the scanner come in. Thanks again for the responses! Tim On Tue, Apr 14, 2009 at 10:05 PM, Daniel Stasinski m...@avenues.orgwrote: for logging usage.

Re: iButton anyone?
Hey all, Sorry about being so vague the first time around, I was just wondering if there was anyone with experience with the iButton. I have been tasked with doing some repairs on equipment that use these as a method for logging usage. After 30k uses, it prevents the machine from working anymore. My boss tasked me with finding out how to get around this little problem, so I've been swimming in iButton information for the last week or so. So far I know which model, and I am waiting for the writer to come in the mail. I'm also looking for a decent scanner that will read the chips, and haven't made my final decision on which one to purchase yet. I was hoping that there was someone that has some experience with this and might be able to help solve my problem. If not, and this sounds interesting to you, I'd be glad to bring it to a meeting and see what we can do with them.

As a security device it is a key with a unique electronic number in it that would serve to tell the system that that key, and only that key was present in the system and was therefore authorized to do whatever teh system was programmed to do. On the other hand, depending on how it was programmed, it could be doing nearly anything else the designer built into it. Personally, I vote for its unlocking the front door, turning on the coffee pot and starting World Wat III all at the same time, all of which seem to be within its capability.

What is good to do with them is a function of what you want to accomplish. The phrase dealing with them does not define a goal to be met. Perhaps if you were to elaborate a discussion would start.
