This is getting dealt with this weekend...
I like the orange extension cord running up the front to a 12vdc power supply mounted on a din rail laying across the shelf.
They've got 6 monitors running off 1 VGA port with a shitload of splitters and boosters.
Pics once the new blackbox climate controlled cabinet and serious wire management is complete will follow.

The sign which says "DANGER: HIGH VOLTAGE" seems unnecessary to me. Anyone capable of reading that sign should also be capable of recognizing that any object which is constructed largely out of ribbed porcelain insulating towers with thick wires connected to them probably has 25,000 VAC on it and is just itching to kill you instantly, without provocation, and in such a manner that an open-casket funeral is out of the question.

that's at Johnson Space Center in Houston. There are cryo-vac chambers in Rochester, but nothing like Chamber A. It's where the James Webb Space Telescope is being aligned/tested.
That is a picture of the load testing rig, before we put the actual JWST in there, there will be nearly a dozen cryo-vac tests of the equipment in the chamber to make sure it all works correctly. The inside shroud, the black painted part, gets down to around 20K (-424F), there's a second shroud outside that that is filled with liquid nitrogen at ~80K, then the chamber wall. Being so cold, some of the initial testing is proof load testing, for example that big silver I-beam structure is basically just a weight, something like 1.5-2x the weight of JWST, you can also see there's one mirror and 2 circular weights up at the top. In that test we pretty much just took everything down to cryo for a few days to see how the thermal predictions worked and to make sure everything survived the trip down and back up.
The current test (that started this week) has what's essentially a full sized replica of JWST with only 2 mirror segments and some mass simulators in place of some of the instruments. I did some looking and found some new pictures on NASA's Flickr page of the current setup. In this test they're doing some optical voodoo that I don't understand,

You continually give people far too much credit.
For instance, one of the companies we sell a swing drive with integrated sensor told us recently they no longer were going to buy the swing drive, but still wanted the swing sensor.
It never occurred to them that we designed the sensor to work specifically with the sensor ring in our swing drive. There response was, "Sell us the sensor/conditioning box/sensor ring, and we will take the other swing drive apart and install your solution."
And these are educated people, not your average dropout off the street.
