After I clean my sensor with a cleaning kit, I go outside and find a cloud-less part of sky and shoot it with a small aperture opening, slightly underexposed. If you see no dark smudges your cleaning was successful.

A closer look at the object:
there are two "circuits" in the ring pattern, and an additional edge. The outer, second-in, and fourth-in rings are all connected via the conduit visible in the vertical plane - on the negative Y-axis of the center. The center dot "pad", first-in, and third-in rings are all connected via the conduit visible in the vertical plane - on the positive Y-axis of the center.
These two circuits do not appear connected from the top.
The coating over this object felt like a hard plastic or lacquer.
If you zoom in, it looks like the coating has been etched with a spiral ridge pattern, possibly allowing the metal (copper?) of the sensor to be exposed in areas.
The object looks like it should have been mounted with screws, as there are insets for them, but this is in a hole in some concrete and it's been tarred or caulked into place.
My guess is that the ridges allow for, perhaps, moisture to lessen the resistance between the two meshed circuits and that this value is measured, and perhaps triggers something.
I need some help with this. I googled for a while and came up with... NOTHING.
see the previous picture for a wider-angle shot and the precise location of this object.
Still some dust on there, but not so bad.
I used the same curve as in the before picture to exaggerate the dust.
This is an out of focus shot of my lcd screen. The darkness on the left edge is probably because of the way I was holding the camera or variation in the lcd brightness exaggerated by the curve.
before I did the curve, it just looked all white. I curved it heavily.

i really don't know what happened here. the agfa optima even protects your film if you accidentally open the camera so only the last 2 pictures are ruined.

Right after Trent's birthday party, I noticed these spots on photographs of a white wall. The last photos in his set seem fine... eep.
Crank position sensor installed with the little cable duct cleaned up and back in place using a couple of new M6 nuts as I couldn't figure out how to get the old clips to reinstall.
The sensor just sends a pulse to the ECU triggered by the notches on the damper wheel thingy going past.
I suspect that this is also the source of the engine rev information and that the position is actually sent by the bit of the wheel that has the notches missing
Battelle researchers developed a unique load sensor in the 1980s which, when attached to an operating dragline, transmitted load data to a remote receiver. Lowell Strope demonstrates how data from this experiment indicated that loads on wire ropes used in surface mining are much higher than previously thought.

22nd January 2011 - 365 day 22. The other day, when I was cleaning my camera's sensor, I noticed some attractive iridescent patterns illuminated by my head torch. So I recreated the moment for today's picture.
The BFS 33M true color sensor succeeds where existing RGB sensors reach their limits by using the lab color space. The BFS33M uses fiber optic cable based optics allowing the placement of the detection optics in very tight spaces. The sensor also provides seven channels and three digital outputs for set-point detection and can use the serial interface to not only configure the unit, but also output color data to perform color evaluations.
A visit to Times Square in Manhatten, NYC. A rather cool Spring Saturday afternoon, brings the people out. There were more people in some of the blocks, than I would see in my travels all day in Philadelphia. It's hard to explain the magic of this city. Take a look at the large version of this photo and scan over the faces.
Here is all the stuff I used. This is the Copper Hill Wet/Dry kit I photographed earlier, plus a medium Giottos blower I bought separately a few weeks ago.
The blower didn't remove much dust. The wet cleaning removed a lot of the dust, but there was still some left. I went back with the brush to try to remove some. I removed a little, but the rest was going nowhere or only moved around. I'd say the blower and the brush are only marginally effective. I ended up doing the wet clean from left to right three times (three separate cleanings/swipes). There was one stubborn piece of dust at the lower right, so I tried swiping from bottom to top. This alternative was mentioned in the cleaning instructions. Swiping bottom to top twice did the trick. In the end, the sensor basically got 5 cleanings.
I did take a test image at f/22 after the cleaning, and I do still have some dust on the sensor. I have less dust, and the dust is smaller than before. I am somewhat disappointed because the sensor looked totally clean to me through the loupe. I don't know if it is possible to have a 100% dirt/dust-free sensor after a cleaning. I've heard of people getting their camera back after a professional cleaning with dust still on the sensor. I guess there is only so much that can be done.
I have only taken a handful of images since the cleaning, so I cannot draw any conclusions about the efficacy of the cleaning.
OK, I reluctantly admit that there are times when I'm _not_ the biggest geek in the room. But if you want the title, you'll really have to earn it.
