In my opinion, no self-respecting nefarious device would be complete without some sound effects. Perhaps when you activate the first switch you hear a motor slowly come up to speed as the light is "breathing". When the second switch is activated, a second motor comes up to speed. Upon activation of the third switch, use a sound like the "steampunk giant robot" from the Mega Stomp Panic: http://www.thinkgeek.com/product/ef56/ along with activation of a jumbo-sized version of the vibrator motor that is in your cell phone so the suitcase would twitch a bit. I can't wait to see this come together! -Rick

As you're including ionizing radiation, Max, I trust you are going to have a radioactive source (maybe your radioactive balls??) and make use of that Geiger counter that I fixed for you?

Also, shouldn't it be "The Amber light breathes three times..." or do they spell "breathes" differently in the States too? BTW, love those old switches and lights - I had some too until I moved to Aussie, had to be ruthless. I might be able to get some really big lights (like 1 inch diameter) though not faceted - since you're going to be in front of a huge audience, would those be useful? I've rescued a few from old substations switchboards.

Hi Rick -- Hopefully I'll have something to show you the next time you pass by my office

But of course -- I'll be taking my radioactive marbles and my Geiger counter that you got working and that is currently happily clicking away to itself on my desk

Good catch on "breathes" (as opposed to my saying "breaths") -- I just fixed this in the article. I love the old telephone switches -- I want to get more, but they are mega expensive. I think I'm good for lights at the moment, but don't you dare throw anything else away :-)

When I moved from Zim to Australia, I didn't "throw away" much, but I did sell off a lot of stuff...amongst which was quite a few of those telephone switches, some old strowger uniselectors, a box of nixies, a box of valves (tubes), some old ferrite core memories....all stuff I'd love to have now, even if just to hang on the wall. Such is life....

Nooooo -- you had some telephone switches and you got rid of them -- tears are rolling down my cheeks...

I would put the Geiger counter in the suitcase and interface it to trigger a very low RPM vibrator. Whenever a certain level of radiation is detected the suitcase would hop around.

That's a good idea -- I do have my radioactive marbles -- plus a much bigger radioactive source -- the trick is going to be getting all of this stuff out to the conference without being arrested :-)

Radio
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.
