It won't change regardless of whether you change hardware on your computer or even use a totally different computer. Every networking device has a unique MAC address that is assigned by the manufacturer and stored in the device's hardware. Hence, it is sometimes also called a hardware address or physical address. Since it is hardware-based, it doesn't change. Each networking device on your computer (wired ethernet card, wireless ethernet card) has a unique MAC address. If you replace, for example, your wireless card, your new wireless card will have a different MAC address than your old one. If you get a new Eye-Fi card, it will have a different MAC address than your original one. However, the MAC address of a given Eye-Fi card is independent of your computer hardware and never changes. I hope this helps. No, the MAC address is a characteristic of the networking hardware in the Eye-Fi card.

Anyway, yeah, I let the people at the libraries know. Hopefully, if they get questions from other people they'll be able to get to the bottom of it quickly. That type of thing is kind of the purpose of this blog. As I figure out things that had been bugging me, I try to post my solution so other people don't have to waste a bunch of time on the same thing. That said, my blog probably comes up on page 100 of any Google search but at least it's there.

If you haven't already, you should pass this info on to the library in case someone else calls with the same problem :o) The suspense was killing me reading this, since I certainly looked up a lot of journal articles via the library but never had the proxy problem.

It could also be that my zone plate isn't great quality, which might account for how blurry it is. I don't know. Yeah, I've heard things about dust problems with pinholes. I'm not sure if the spots on my sensor are dust or some type of lubricating oil used in the mirror assembly. The last time I had my sensor cleaned, the guy at Calumet said I had some oil splotches. Those are harder to remove than dust particles. My camera has a CCD-shake dust removal system but it has failed to remove these splotches, so either the system isn't very effective at removing dust or they're not dust. Anyway, I like the zone plate because there's no physical hole. Therefore, dust has no direct path from outside the camera to the sensor. It seems like you could make a faux pinhole by taking a piece of glass and coating it with an opaque coating then removing a tiny circle of that coating. Perhaps people have done this. This might be hard to do, however, without scratching the glass where you want the light to come through.

I mean to say that f/56 means the depth of field/ focus should cover a lot of the photo. Oops. I mean to say that f/56 means the depth of field/ focus should cover a lot of the photo.

Apparently--this is what Andy tells me--taking a photo charges the sensor and that can electrostatically attract dust particles to the sensor. It's probably worth considering or looking up more info about that. I would think the focus would be soft but clearer on the zone plate image–I mean f/56 means
