After reading this thread, I decided to go see how much dust was on my Digital Rebel XT's sensor.
Quite a bit. I'm betting it's all pollen.
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.
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.
Die CASIO Triple Sensor Digitaluhr Module No. 1170) stammt vom 08.03.1995 und war damals ein echtes High-Tech-Produkt aus Japan. Erstaunlicherweise werden einige Module auch heute bei modernen Uhren noch angewendet. Die vielen Funktionen und das innovative Desingn ist schon ungewöhnlich, wegen der Sensoren am Gehäusering.
Leider ist auch der Energieverbrauch nach oftmaliger Betätigung sehr hoch. Die zwei Batterien halten etwa 2 Jahre bei normaler Benutzung. Die Uhr im Verhältnis zur Größe recht gering und auch angenehm zu tragen. Als negativ zu bewerten ist das Armband - bei häufiger Benutzung reißt es beim Gehäuse. Originalersatzarmbänder sind sehr teuer!
Technische Daten:
Gewicht: 54 g
Gehäusedurchmesser ohne Sensoren: 48 mm
Gehäuse und Armband: Material besteht aus Polyurethan. Der Boden aus einer gebürsteten Edelstahlplatte.
Display: 28 mm, also sehr klein.

Stoppuhrfunktionen
Alarm fünf mal täglich
Höhenalarm-Operationen

Magnetkompassanzeige
Separates Sekundenanzeigerfeld
Höhenmessungen mit Alarmfunktion Kompassfunktion
Zeitangaben und Barometer mit Monitoranzeige.
Mirobeleuchtung in grün
Batterien: Zwei Silberoxyd-Zellen (Typ: SR927W)
Herstellung: um 1994

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.
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.
Bob and Kyle prepare the openings that were drilled for the installation of the backup sensors.

06/18/18 - Portland launched the Smart City PDX Traffic Safety Sensor Project. A partnership between the City of Portland, AT&T, Current by GE, Intel and Portland General Electric, the project has installed 200 traffic safety sensors on three of Portland's most dangerous streets: 122nd between Burnside and Duke; SE Hawthorne between 11th and 46th; and SE Division between 11th and 122nd.
The sensors will help traffic safety engineers design safer streets by compiling information about: how people use streets, including where they typically walk, bike and drive; how fast people are driving.
On Monday, June 18th, Mayor Ted Wheeler joined city officials and the project's partners to celebrate the project and Portland's overall Smart City efforts.

Upon returning from my three week holiday I discovered I had some nasty dirt on my sensor and thus all my photos.
I didn't check my phots and backed them up mid trip using a portable storage device with no preview. So any photo f8 and above has this nasty dirt on it. Well all the photos did but below f8 they blurred and blended with the photo.
My camera is now being serviced and hopefully cleaned.
... and I cropped out the worst ones.
I liked this photo too much not to post it. Someday when I have more time, I'll remove the sensor dust.
Freescale Semiconductor’s MMA7260Q XYZ three-axis low g acceleration sensor is designed to detect on three axes, allowing your end application the freedom of movement and detection it needs. In addition, for multifunctional applications, this three-axis device allows you to select between 1.5g, 2g, 4g and 6g levels of acceleration. This solution is ideal for end products or embedded systems requiring measurement of low g forces resulting from fall, tilt, motion, positioning, shock or vibration.
I just cleaned my image sensor for the first time. I was super nervous, 'cause everyone is always telling me that you can damage them so easily. However, the $75 per-cleaning cost of having it done in-house at a local camera shop, or the prospect of being without my camera for 2-6 weeks if I do it through my best-buy plan is just unacceptable.
With some keen advice from my fellow flickr friends, I found copper hill images and bought their mega dslr kit. Tonight, I used it for the first time.
Although this test is far from perfect, you will plainly see a difference. I didn't get all of the dust off the sensor this first time, but I chalk that up to going extra easy to lessen the chances that I'd do more harm than good. Tomorrow, I'll know for sure how well I did, but the system sure seems to work, and the instructions are very helpful. Woohoo!
*note: these photos are just the blue channel, as that's where you could best see the scum all over my sensor.
