A very different kind of trillion-dollar business from than that covered by Aviation Week. Individual aircraft cost millions. Any electronic component that costs more than $10 is expensive. Most of the circuits that we see and use were designed for people who could - and would - buy 100,000 in a batch. They don't need the trade magazines to tell them what's available; the trade magazines exist to tell us what the big boys have had made, serving a much lighter (and less influential) class of light-weights than Aviation Week gets to cater for. Linear Technology wouldn't notice if Highland Technology and a thousand small manufacturers like it went belly-up. -- Bill Sloman, Nijmegen

They visit us a couple of times a year, and I take them to Zuni Cafe. They sure would notice if we quit doing that. I think I got them to do the new current source chip. I sure ragged them about how the world needs one. And I also told them to do a 3-output power-module switcher for FPGAs: +5 to +24 in, 3.3 and 2.5/1.8 and 1.2 out. We'll see how they do on that one.

You put the WAP gear by the antenna since you can do long runs of ethernet with much less hassle than long antenna runs. In the old days when all the boxes had removable antennas, everyone hacked to get higher gain. Some hacks were just reflectors behind the monopole. Other hacks were cavity resonators. But to think MIT is the source of this knowledge is pretty funny. In fact, the best homebrew wifi antenna designs were out of Australia and Yugoslavia. You can troll alt.internet.wireless. I saw one design that was a metal salad bowl and a usb wifi "fob".
