Perhaps you've heard of TGIMBOEJ? The Great Internet Migratory Box of Electronic Junk is a great concept: a few USPS medium sized flat rate boxes floating around amongst the country's electronics nerds. A sort of cross-pollenation for junk bins.
A box of junk shows up on your door step. Take what you want, add some new gems, and send it back on its way. One of those boxes just arrived here at TE Motorworks.
I needed a forklift when I moved my shop last month.(Of course, everyone just needs a forklift, period.) Besides the stock of steel, the heavy machines and tables, and all of the normal stuff, there's just a lot of, well, Other Stuff, and a lot of it is really heavy. Much of it I keep because I'm planning to use it in some future project. Some of it is here because I just haven't gotten around to getting rid of it yet. And some of it is even photogenic. Here's a collection of my once and future useful stuff.
Thousands of manmade pieces of space junk orbit the Earth, threatening astronauts and unmanned missions alike. Now the U.S. Air Force Space Command wants an electronic "space fence" that could track any orbital object larger than two inches in width.
Such a surveillance system would require a global network of sensitive S-band radar stations that operate in the gigahertz range of the electromagnetic spectrum. The U.S. Air Force currently relies on a system dating back to 1961, which only covers the continental United States, and can only track objects 20 inches in width or larger.
