You need to be steady handed to replace the battery in this one!
... it's under the transducer and glued to it.
The case had to be sawed open.

I got the sensor of my camera cleaned. These are the actual photos on which you can see the before and after state of the dust on the sensor. I think it was quite necessary to have it cleaned :)

Ideal for municipal and industrial water, potable water and wastewater, MVS10 and MVS17 Ammonium Sensors offer high performance at an economical cost. Water treatment engineers in need of a versatile and cost-effective Ammonium measurement solution will find that the new MVS10 and MVS17 Ammonium pIon Sensors from Electro-Chemical Devices (ECD) provide a stable and economical in-line measurement platform, helping plants and processes operate smoothly and efficiently with lower operating costs.

Line array sensor 512 pixels. For a new detetor to capture flying moths at night. Film is ready to make the PCBs. The aim is to build a tunnel with laser detection for flying moths at night.
The line sensor effective lenght is 64mm as detector. The exposure is done with a 650 nm laser line.
this is a general piece about dirty sensors.
A heads up to all those 'spots' in
your sky photos that you may think is a dirty lens.
I moonlight at our local camera shop and one of my tasks is to clean sensors.
I've cleaned a slew of them now and have seen some stuff!
A- not the worse I've seen, but a good example of a dirty sensor!
B- same sensor after cleaning
C- a shot of the sky to show what a dirty sensor adds to a photo(not the same sensor as A/B)
D- a test shot to see how dirty the sensor
You can clean the sensor yourself or have it done professionally.
There are many tutorials on the web about how to do it.
Just be careful ... the sensor IS your camera.

photo taken after bringing it to Nikon for cleaning.
so i got a call yesterday afternoon from Nikon that my D40 was ready for pickup. so i passed by before going to work this morning and took this test photo. impressive!
it's good to be back!
Sensors are able to measure temperature, humidity, pressure, sound, light, magnetism, acceleration and various chemical properties in their vicinity. This installation illustrates how quickly and efficiently such sensors work.

The sensor, a Honeywell SS495A1 ratiometric Hall-effect sensor, is glued to a small brass tab that is then bolted into the Brooxes Better Gear Guide. The sensor then plugs into the Pololu Robotics Micro Maestro controller and is sensed as an analog device.
Here's a touch sensor. Just touch the bare wires on the lower right part of the board and the LED lights!

Self explanatory. Showing that if the camera allows it one can almost fill the entire 4x5" film surface with shots taken with the GFX and then stitch them to a panorama. Something like what happens with the Gigapixel Gigapans.
Here's some before and after shots of my project to clean my sensor. As you can see in the before, it was a flippin' mess. In the after (though dark, sorry dreary day) you can see the lack of dust.
I used a Giottos Rocket Blower, 3 #2 Sensor Swabs and Eclipse liquid from Photographic Solutions, Inc., and the Sensor Brush from Visible Dust.
BTW, #2 sensor swabs don't actually come into contact with the XT's sensor unless you use them vertically. The Sensor Brush does a great job, but you really gotta get it charged up with static. They should make one with fuzzy slippers and carpet.
Balluff's new liquid-based inclination sensors measure the deviation on a horizontal axis of up to 360°. With an extremely high accuracy of 0.1°C, a resolution of 0.01° and a temperature drift of just 0.01% /10K, they are the ideal choice for solar -thermal power plant and renewable energy applications that require angle measurement or constant rotary monitoring.
BSI inclination sensors feature a robust metal housing with an IP 67 enclosure rating that is easily installed into systems with limited space due to their compact housing size. With an expanded temperature range of -40°C to + 85°C, they are ideal for outdoor applications.
Sensors are embedded in the new type of bendable concrete - engineered cement composite, ECC while the cement is poured onto a section of the road at M-City in Ann Arbor.
Civil and Environmental Engineering Professor Victor Lee, Visiting Professors Esayas Ftwi and H. Süleyman GÖKÇE as well as a group of Michigan Engineering graduate students work with the workers from a local cement company Arbor Masonry to mix and pour new type of bendable concrete (engineered cement composite, ECC) into a section of the road at M-City, a driverless vehicle test facility at the University of Michigan. Before the new cement is poured, electronic sensors are installed and embedded in ECC to measure its performance.
Victor Lee, an engineering professor at the University of Michigan has developed a new type of flexible concrete known as an engineered cement composite (ECC). He developed the new new material by reinforcing cement composites with smart fiber.
The flexible concrete doesn’t need expansion joints in driveways or sidewalks the way regular concrete does. It doesn’t need rebar to keep it strong and you only need 4 inches of it vs 8 inches to use in a road or driveway. Finally, the ECC is flexible and not bristle like regular concrete.
The material has a compressive strength similar to that of regular concrete. But while normal concrete has a strain capacity of .01 percent, ECC has a tensile strength capacity of 3 to 5 percent, or about 300 to 500 times as much, making it far more ductile.

This cardboard box was packaging for a small lamp from Ikea. The form factor is a little more bulky than the pencil box, and the box came with strange cutouts in the surface.
As usual, there's a backstory.
I've always been a sweat equity kind of guy. Buy trashy old houses, fix 'em up and enjoy for a while, maybe sell later. I've rescued a few homes from the trash heap over the years (in the process again as we speak) but I rarely took the kind of before/after pictures I should have. Photography to me in the eighties and nineties was an avenue for producing art or commercial images--I rarely picked up a camera for documenting my life and work. This I regret.
Enter digital photography, and the opportunity to shoot endless images for free. I bought my first serious digital camera sometime around 1998, a Sony DSC-D770 with 1.3 megapixels and a pretty good lens.
Yeah, that's no typo. One-point-three megapixels, and retail price was upwards of $1,400. It made glorious images provided you didn't want them enlarged beyond 4X6, and you had plenty of light. And I do mean glorious images, with extraordinary delicacy of tone.
I've always wondered how those images would look if I ran them through my current workflow. So, here are a few of my rare "after" pictures from that early digital camera, run through LR3 and PSCS5. Original images were 1.3MP JPGs, taken circa 1998.
