Thanks, it's been fun.
Ever since the arctic was promised with TEM00 and 1.5 mrad I have been chasing.
The BDR-209 is close to what we thought we were going to get....8 years ago...?
So now we have affordable 6+ watt diodes....with divergence like a Chinese fan.
I just had to fix it.

This is our front yard (airport control tower right above me).

Hot clear skies, then cloudy, some rain, then clear again roasting us but it isn't the hot time of the year yet.

Is it low humidity, I know it's a desert so....low humidity Right?

That makes it a lot better, you just have to stay hydrated.

Now Miami, WOW you walk out of the AC and it's like your standing in hot soup.

Yes, but had help. They are 2 meter diameter Ku-Ka band, up to 30 GHz.

Damn spammers ...

Anyway - took this a little after 11PM the other night. Sunset is currently at 11:20PM here but it never really gets dark, what we get is called "civil twilight" which is light enough to play golf or read a newspaper at night. The sun currently only dips ~5 degrees below the horizon. The days are currently 19 hours and 25 minutes long. Sunrise at 3:54AM.

More on that here: Sun & moon times today, Yellowknife, Northwest Territories, Canada

Hint: don't look at the winter solstice, those numbers are depressing... :p

Cross post from the "high pressure mercury lamps" thread in a darker, dingier part of the forum. Two medium pressure mercury lamps, one (non working) specimen from the 1940s, and an Osram-GEC from a decade or two later. As a lamp collector I virtually hit the holy grail with these and was delighted to get them.





For those interested, the pure mercury vapour spectrum is quite sparse and only has a few spectral lines. They release tons of UV, and plenty of violet - a 404nm and 436nm spectral line, as well as some blue, green, yellow and trace amounts of red.

Bought this rubber snake on ebay: http://www.ebay.com/itm/230823042078 - Put it at the door step of a coworker and later heard screams in the night when he went to his room :p

I don't know why, there are no coral snakes in Afghanistan.

I love it, I'm reading this just as I finished up a diversity training class at work!
I'm sure they would find this wrong in so many ways, maybe that's why I think it's funnier than hell. :eg:
