Just testing some new papers I got at the craft store. :) The dress is OOAK and available now, see profile for info ♥
Testing one, two and now, three.
Radio frequency testing has begun on the first Orion spacecraft that will fly around the Moon for the Artemis 1 mission, just two weeks after thermal and environmental tests were completed at NASA’s Plum Brook Station in Ohio, USA.
Electromagnetic compatibility or EMC testing is routine for spacecraft. All electronics emit some form of electromagnetic waves that can cause interference with other devices. Think of the buzz that speakers give out right before an incoming call on a mobile phone.
Spacecraft electronics can cause similar interference, but out in space such interference can have disastrous consequences, so all systems must be checked before launch.
EMC tests often take place in a special shielded room constructed of metal walls and doors and foamy spikes (aka absorbers) that block out unwanted external electromagnetic radiation, like ESA’s Maxwell chamber at its technical site in the Netherlands.
Though not an EMC chamber, Plum Brook’s thermal vacuum chamber is made of aluminium that does provide electromagnetic shielding, making it a suitable substitute.
To test electronics, the spacecraft will simulate a flight in realistic conditions with most of its subsystems and equipment powered and in operational mode.
The electronics are first tested for compatibility in this electromagnetic shielded chamber. Equipment will be switched on to test whether they do potentially disturb one another.
In the second round of tests, electromagnetic fields will be applied using antennas around the spacecraft to test the susceptibility to interference from external sources. The Orion capsule is equipped with electromagnetic field sensors to take measurements as the disturbance frequencies are injected into the chamber.
While all subsystems are a potential source of radio frequency noise, of particular interest are the transmitters that intentionally generate radio frequencies. These can easily disturb other equipment sensitive to electromagnetic noise, like GPS receivers, tele-command modules and other communication elements.
ESA experts are on site monitoring all tests alongside NASA colleagues as Orion moves closer to its first flight without a crew around the Moon.

John Deere 8360RT (lead tractor) under test at the University of Nebraska Tractor Test Laboratory. The instrumentation vehicle (yellow) and following tractor provide loading for the test. Part of the test involves multiple laps around the lab's concrete oval track. I took this photo while visiting the Lester F. Larsen Tractor Test and Power Museum in Lincoln Nebraska. tractormuseum.unl.edu/
Ricoh TLS 401, Fuji Superia 400 (accidentally shot at 200. Oops!), Auto Sears 55/1.4 w/ Camron UV filter. Negatives Scanned.
Test roll through the camera body that apparently has seen no use since 1984. The meter doesn't work, so I used the LightMeter app by David Quiles Amat on my Galaxy Note II.
Disclaimer in regard to focus: WOW this thing's viewfinder is terrible. The waist-level finder is OK, but small. The eye-level finder is practically impossible, plus mine is cracked and filthy inside... Just crossed my fingers and fired the shutter.
37611 with 4Z98 Derby Litchurch Lane to Carlisle Kingmoor on 6th July 2015.
The move was to test gauging for the wagons on the Cumbrian Coast route and the cable seen hanging from the rear cab is part of the monitoring equipment.
This all added to the EE traction-fest which was at the time on the route north of Barrow.

A toy? Not really, this lens can really deliver amazingly sharp results!
--- Lessons learned:
+ best way to get the grips is to use the lens with the cam (in liveview) tethered to a tv set via DVI
+ the lens should not be used on maximum tilt -- you cannot get sharp results with this adjustment
+ the two lenses in the Lensbaby are not coated, backlight will lead to overlit blurry results ...
+ This is a 50 mm lens, minimum object distance is approx 0,6 meters ...
+ shots were take with the 4.0 aperture, ... 5.6 has a wider sweet spot, but less wow effect
+ works fine in Av-Mode
--- This is how focusing works:
Point the optical axis of the lens **exactly** towards the spot you want to focus; adjust focus ring - if possible in zoomed liveview mode.
--- This is how it not works:
Leave the lens as-is (no tilting); try to focus on an object in the corner of the image via turning the focusing wheel.
--- One problem I came across:
The 5DMkII works fine with this lens in Av mode, even better with additional liveview, but does *not* adjust exposure in *zoomed* liveview! => Firstly wait for exposure adjustment, then zoom in, adjust focus, if possible, zoom out again, shoot. :-)
NAWCAD Trenton, located in Mercer County, New Jersey, consists of about 66 acres with a total of 96 buildings and structures. The center was used to test jet engines, alternative fuels, turbines, and engine starters.
The main "hangar" at NAWCAD. Im not exactly sure what this building was used for but there are slots in the ground about a foot deep and there are spikes and stands that stick out of them. It looks like you would brace something on top of them. You can see the slots better in this picture.
Photos here were shot using old Canon FL/FD lenses mounted onto the new compact mirrorless full frame Sony Alpha A7 released on November 13, 2013 in Japan. The lenses are all manual focus due to the fact they are old legacy prime lenses. The Canon lenses used for this test:
FD 35mm, f2
FL 50mm, f1.4
FD 135mm, f3.5
FD 135mm, f3.5 (with PL filter)
This photo was taken using the portrait focal length, FD 135mm, f3.5 lens.
As seen through my new macro lens, this is the test (calcium carbonate structural shell) of a small sea urchin that was unknown to science until one was purchased on eBay in 2006 and subesqently described by Natural History Museum scientists Simon Coppard and Heinke Schultz. I bought this test on eBay right around that time, unaware of this fact.
::::::::::::::::
Sea urchins are members of the phylum Echinodermata, which also includes sea stars, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and a mouth locatted ventrally. This species is from New Caledonia, and this particular test is about 1.6cm wide.

Test of an inexpensive Neewer LED Macro Ring Flash FC100. The subject is about 3cm across and is a tricky one - shiny brass. At this distance the flash works well with a shutter speed of 1/160th, f8, ISO 200 but the flash lacks power. If I move away to a distance of half a metre I can't get a decent shot at ISO 200 even at f2.8, the flash isn't powerful enough. But for the money it's very good for real macro work.
Tilt test model showing a large scale RT model on the tilting platform. Model is in the LT museum Covent Garden.
Tested these brands and some more. Will need some time to round up the results...
Too many things too do, too little time.

Test Roll of Lomography CN 400 in my new Lomogrpahy Konstruktor DIY SLR.
Overall the pictures are okay. I don't think I'd be using it that often, the 1/80 shutter speed is just a bit too slow unless you stop and stand still.
Also it likes to eat film.

A Bristol Siddeley-Maybach MD655 engine, from a BR Western Region Class 52 diesel-hydraulic locomotive, under stationary test at Swindon Works. Taken on an open day, Saturday 13th September 1975. The engineer in charge ...a white-coated, bespectacled, middle-aged man... sat behind the window of a control room at the top of a flight of steps. From time to time he would notch up a handle on his console to increase the engine revs, which were displayed as flickering red numerals on a screen. In the confined space this produced a most satisfying din.
Testing Mecaface and the EpicFigRig more, first time rigging them all and posing in Blender.
