+-   New LBA Lighting Choke Feeds Tower Strobe Lights-> on Monday December 21, @09:53AM pstox

Submitted by pstox on Monday December 21, @09:53AM
pstox writes "Providing an AC feed to strobe lighting systems on high power AM towers can be problematical. The ring-type chokes often used for tower light feeds on high voltage towers often do not function well under the low pulse loads of stroboscopic lighting systems. These problems can cause overheating and burn out of seemingly adequately rated ring transformers!"

+-   Hear No RF Evil - See No RF Evil - Through The Loo-> on Thursday November 05, @12:39PM pstox

Submitted by pstox on Thursday November 05, @12:39PM
pstox writes "LBA asks the Old RF Curmudgeon to put on his magic glasses and look through the swirling mists of spectrum policy. In this several part (he’s still looking) series the Curmudgeon will share with us the fantastic visions of spectrum usage and policy that he tunes in. Look with him carefully, as the spectrum path is yet untrodden, and unknown monsters abound along it!"

Comments: 1 +-   Cellular Modem in Embedded Product? on Wednesday November 04, @11:18AM Anonymous Coward

Submitted by Anonymous Coward on Wednesday November 04, @11:18AM
An anonymous reader writes "We're a startup electronics company and we're trying to improve our data link in one of your products. Right now we're using a direct radio link — RF transmitter and RF receivers. The issue with that direct radio method is obviously range, and its difficult to get a FCC license on high power radios. We'd like to use a cellular network modem to be embedded in our device, like the Amazon Kindle, and would be happy to pay per kilobyte of data sent. We're pretty good with electronics design, but have no idea on how to get started with this thing, and Google searching has been fruitless. So how do we go about using a cellular modem in our products, without having to buy cell phones and use the actual phones as a data link? Anyone have any experience with this or could help out and tell us where to start?"

+-   Fractal antenna arrays proposed as energy source-> on Monday November 02, @07:53PM sterlingda

Submitted by sterlingda on Monday November 02, @07:53PM
sterlingda writes "Jack Passerello, who was involved with the invention of the first computer chip, proposes that the fractal antenna technology that is used in cell phones could be engineered to capture naturally-occurring electromagnetic waves and convert them into usable power. An engineering breakthrough would be needed, along with a multi-discipline cooperative approac, to get sufficienty coherence from the wide array of miniscule power inputs."

Geeks in Space is Slashdot's "Whenever we feel like it" radio broadcast. Brought to you by The Sync, and hosted by CmdrTaco, Hemos, Nate, CowboyNeal, and wheover else we can fit in the spare bedroom in my house.

We talk about whatever we feel like. Sometimes it makes sense, usually it doesn't. But check it out anyway. We like it.
