I am very big fan of her and really envy her!!! but I have heard that later she is using <a href="http://www.aiglemed.com/mobility-aid/">Powered wheelchairs</a> because of some disease. Is this true or just another rumor.

I had a meccano kit as a kid (some bits I still have. And I found some more on a flea marked a few years ago too). What I remeber most is reading the sparepart sheets and drooling over the parts that I never got my hands on.

My vote is for Meccano (similar to what was called Erector Set in the US), rather than Lego. http://en.wikipedia.org/wiki/Meccano Initially, Lego was (or seemed to be) more oriented toward building buildings, rather than machines, so it was not as compelling to me. Check out that locomotive in the Wikipedia article. I built my first four-wheel drive electric car with Meccano. Too bad the to get real power, I had to use the electric motor that used AC from a wall outlet. Kind of restricted mobility. But it sure could climb. Hey, come to think of it, that may be why I don't see a future in battery-powered electric cars to this day!

Wow! That is a really neat LEGO design. I wonder how long it took to build and how much it cost!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
