01TheOne Men's Zerone Binary Fashion Watch #ZE102G1
$129.00
The 01 The One Men's Binary Fashion Watch is a perfect gift for any hip, tech-loving individual. Constructed with a stainless steel case, the unique timepiece includes a stainless steel bezel, and a black leather wristband with an adjustable buckle clasp. A strong mineral window shields the textured black dial face, which features green LED lights that display the time in binary code. To crack the code, simply add the numbers on the top row to equal the hour. The numbers on the bottom row add up to the minute. Powered by digital-quartz movement, the watch is water resistant to 99 feet. It comes packaged in a sleek metal 01-logoed protective case.

I am crazy about mine! It's a showstopper and a great conversation starter. It also is enhancing my ability to add quickly and accurately.

I DO wish it also showed the date, though.

I am a female with a tiny wrist, and the watch is, indeed, massive. But, the size seems to emphasize the fine quality of the stainless steel bezel. The lighted diodes against the green motherboard face give the watch a very attractive and distinctive look.

I cannot go anywhere without getting admiring comments.

It also keeps excellent time. I often check it against my radio-controlled watch for accuracy.

When I ordered it, I thought I would receive a cute, gimicky, but flimsy and overpriced item.

I was very please to find it to be a solidly made, first-rate timepiece.

The Definitive Guide to How Computers Do Math : Featuring the Virtual DIY Calculator
$39.95
The Definitive Guide to How Computers Do Math : Featuring the Virtual DIY Calculator provides an excellent view into how computers _really_ perform math. While not a complete introduction to the subject (I would recommend learning a bit about Boolean logic and digital circuitry before starting here), it does offer a complete, thorough, and thoroughly fun journey to creating your own "working" computer. Along the way, you will learn the fun and fundamental details behind the mystery and magic of computers.

I've used the material (the book's CD-ROM includes bonus material) to teach computer architecture classes to students as young and middle-school. I've also used this book as a prize to up-and-coming computer science or electrical engineering students in the local elementary and middle-school science fair.

The author, Clive ("Max") Maxfield, has an engaging and entertaining style. You will likely enjoy his other books including Bebop to the Boolean Boogie, Third Edition: An Unconventional Guide to Electronics, which I also highly recommend.
