We have been encouraged to spend some of our remaining training budget by taking a week-long seminar in September. I am looking for something concerning FPGA design, wireless networks, or just general engineering. My preference would be somewhere in southern California, but other places may be negotiable. Any suggestions?

Hi, This is the first of a series of related posts. I figured it best to make sure the groundwork is in place, first... On any *wired* network (save the wireless complications for later) using a star *physical* topology beyond 10BaseT, there is a potential for multicast packets to NOT arrive at all nodes coincidentally (i.e., ignoring "speed of light" propagation down the wire). Pre...

User solar power to save battery life? At least have a couple out of 5, and I can try to work on the others. ...

Any suggestions and hands-on experiences with both? What puts me off with Lantronix is that they have different formfactors for wired and wireless and that the driver installation on the PC requires .NET to be installed (a w...

Hi, I want to use sme WiFi-enabled PDAs as "wireless terminals". I.e., in much the same way that X terminals operate (though obviously not using XDMCP, etc. -- OTOH, that would make life a lot easier! :> ) A browser interface is out because the browser has functionality that the application can't disable (e.g., history, font selection, etc.).

How popular is that old standby async/sync serial data in new embedded designs? I know there are lots of other technologies coming into play from ethernet to wireless, USB, etc., but what percentage of your new designs are using RS232 or RS485? I still see it on almost every project. If not as an intended interface then at least for debugging. Your comments are appreciated. Scot...
