Cool. I'm planning on showing up again tonight, with those plotters I
mentioned a while back, since there has been some interest in them. I pulled
them out of the storage warehouse last last night, just on the chance that
someone might want them. I think they work, but it's been years since I've
done anything with them. So, even if they don't, well, hey, the price is
right: free! Oh, and the dust on them is included at no extra charge. ;-)
I don't have the pens, but there appear to be quite a few on e-bay (Search on
"HP plotter pen".). Also, I believe that it's possible to refill the pins, but I
haven't actually tried this myself, so some trial and error experimentation
may be needed to find an ink with the correct viscosity, drying characteristics,
etc. It may also be possible to hack the pen holder such that it will work with
an alternative pen (e.g., a Sharpie). Someone with some plastic modding
experience would be required, though.
One of the things I had thought about doing with them is to replace the pen
with a focused/collimated LED to produce a photo-plotter, replacing the
paper with film. I also toyed with the idea of using a UV LED and directly
plotting on to a photosensitizied PC board, but never got past the thinking
part (Too many fun projects, not enough fun time.).
I'll also bring my LED light bulb. It would be nice if some one can bring a
lamp to screw it into (standard "Edison" base), since I don't have an extra
lamp that I can bring (since I'm at work, and forgot to bring a lamp in from
home).

I don't do laptops. A computer isn't a real computer unless it weighs 30,000
pounds or more (Hey, think I'm kidding? Look up the specifications for the
IBM 3090 mainframe series! And, yes, I once had an IBM 3090-600J machine
as a "personal" computer! NICE!). ;-)
