Hubdub Predictive Market
Monday, 28 January 2008 10:38 P GMT-06
I saw an article on Yahoo News today about a new predictive market that has been set up for people to bet pretend money on the outcome of news events. The market is called Hubdub. It will be interesting to participate in this as an experi

Group Think in Football
Sunday, 27 January 2008 11:18 P GMT-06
I have written a couple of articles about predictive markets (Gambling, Predictive Markets, and Product Development, and Predictive Markets), and recently I've started reading the book, The Wisdom of Crowds by James Surowiecki. More years a

Vitesse Oscillosoope on Chip
Thursday, 24 January 2008 9:35 P GMT-06
Measuring signal quality of very high speed, fast edge rate signals is very challenging in signal integrity. Signal quality can be inferred indirectly through measuring the bit error rate. Bit error rate measurements can be straightforwar

700 MHz Spectrum Auction
Thursday, 24 January 2008 8:44 P GMT-06
The FCC is auctioning off 62 MHz of spectrum in the 698 to 806 MHz frequency band. According to an article in a recent Wireless Design & Development Magazine, the 700 MHz band is ideal for wireless broadband services [1]. Companies pu
MEMs for Digital Timing Circuits
Monday, 14 January 2008 10:01 P GMT-06
I previously wrote an article about a new start up company, SI Time, that has developed a new type of clock generating circuit based on microelectromechanical systems (MEMS). I have not heard about their technology since I wrote that article,

Winter and ESD go Together in Wisconsin
Saturday, 12 January 2008 2:54 P GMT-06
It's the middle of winter, and that means that cold dry air here in Wisconsin. For the electronics engineer that means electrostatic discharges are happening all the time. As I wrote about in a previous article (Strange ESD Phenomena)

60 GHz Wireless Radios
Tuesday, 1 January 2008 7:54 P GMT-06
There was a good article in IEEE Communications Magazine about the design trade offs for 60 GHz radios [1]. The 60 GHz band is unlicensed world wide, so there is commercial interest in using this band. The main advantage is that at such a
