Help empty my attic!

My wife says it's time to clear out stuff from the 20th century. Things that date back decades ... books, optics, old gear.

Hardback copies of my first book, The Cuckoo's Egg. Hardback. New old stock, unread. 323 pages printed on the finest quality 55 pound Glatfelter paper.

This book is straight from 1989, back before my hair turned gray. It's the true story about how I caught a spy over the early Internet.. Some of the technology feels antique (2400 baud modems), and the author feels a quarter century older. So get a copy while I'm still able to sign it..

By default, I will autograph this book to you. Alternatively, I'm happy to sign it to a friend of yours, or leave it unsigned. (tell me what to do in the comments section of the order form)

$20 - free shipping, anywhere in the world. (I will send your book via media mail, which typically 8 to 10 day delivery). (Also, send me email if you want a copy of Cuckoo's Egg in another language - I have a few in Czech and Dutch; possibly one or two in Spanish and Chinese, and maybe a couple other languages).

Each of these books comes complete with book jacket, 323 pages, lots of nouns, verbs, prepositions, and even a few participles (whatever thosea are). I guarantee that I wrote the whole book (six months behind a MacPlus during 1988)

If you want 10 copies, oh, do I have a deal for you! (yep, I have about two dozen of these books, still in their original boxes)

Buy a copy of The Cuckoo's Egg and make my wife really happy...

Beamsplitter Cubes -

I have a few dozen beamsplitting cubes made by Melles Griot. These are glass cubes made from a pair of right-triangule prisms cemented together. Shine a light (a laser or any other light) and half goes straight through, the other half goes out at 90 degrees. (well, 1 percent or so is lost in transit).

Or you can use one as a beam combiner.

These are neat to fool with - precision optics, specially overcoated, neat, nice reflections. Like most highly polished optical surfaces, treat these delicately if you wish to use them professionally. But they make great classroom displays (students will fool around with 'em and get fingerprints on them). They're cool to put on a sunny windowsill - rainbows & beams come trilling off of 'em. (I've used these in measuring the speed of light - a modulated laser pointer is split into a long path & a short path; both got to pin diodes and are displayed on a dual-trace oscilloscope)

Most of these beamsplitters are 1 inch cubes (25.4 x 25.4 x 25.4mm). Others are 50x50x50mm, and I also have at least one 60x60x60 beamsplitting cube. . Interested? I'll send the whole lot to you for a mere... uh, I dunno. I haven't finished this part of the web page yet, and I haven't even counted how many of these optical gizmos I have. Probably about two dozen.
