Using a regular Arduino board to do the testing. An Arduino Mini Pro will be used in the final version.
PNNL researchers release sensor fish at Ice Harbor Dam as part of testing of a new turbine. The sensor fish is an autonomous sensor that measures pressure, velocity, and acceleration that a fish experiences as they pass through the dam.

A nice little 126 film camera with the "big red dot" soft touch shutter release button. Aluminum outer shell. Two shutter speed 1/40 and 1/80 selectable via a ring around the lens barrel. Simple one element lens (42.1mm) with fixed aperture (f/11) and fixed focus. It has a socket for "magicubes" which are fired mechanically and require no battery. The name plate is missing from this sample.
My Baroesque Barometric Skirt reflects environmental data, plus my personal temperature - it's a reflection of the self within the bigger picture. What I mean by this is that how I pass through and interact with the ambient environment interests me. To visualise this passage I have created a skirt that uses sensors to glean environmental data in the form of a barometric sensor board, its data more commonly familiar to those who track and predict weather. To the viewer of the skirt, they will see colours changing in real time on four rays of RGB strip, one for each sensor reading.
This is how I’ve put together the electronics inside the skirt: the aforementioned barometric sensor board protrudes from the skirt and gleans the ambient temperature ( Celcius C) around it, the other sensors on the board collect data and via algorithms in the code work out the altitude (meters m) and pressure (Pascal Pa). I’ve used a Shrimp kit, which is similar to the Arduino Uno, that comes as a bag of components and soldered it onto stripboard. Another temperature sensor, measuring my temperature sits on this stripboard, Four lengths of RGB LED strip radiate from the Shrimp circuit and both the stripboard circuit and the RGB LED strip are sewn onto what I call an ‘apron’, which sits under the skirt and is detachable for washing purposes and also as I like to fashion my electronic circuits as interesting pieces to be viewed in their own right.
The code takes the readings from the sensors and runs an algorithm firstly to convert the data into Celcius, meters or Pascals, and then runs another to mix the colours appearing on each corresponding RGB LED strip. There are 7 colours I’ve set to pass through, the lowest reading being blue, followed by cyan, white, green, yellow, magenta and finally red for the highest reading in each sensor reading data band.
It took a months to create the skirt as there was so many iterations between experimenting with circuits around how to make my idea come to life and creating the skirt, testing paint on fabric, choosing a visual metaphor and style of the skirt, then making the skirt. Next finalising choice of the electronics, coding, prototyping, then transferring the circuit to stripboard. Finally soldering everything together and then debugging, testing, making changes to the code, before eventually putting the skirt and the electronics together.
The Baroesque Skirt’s weather artwork was inspired by the characters Amaterasu & Kabegami from the game Okami.

Sensor after I cleaned it. There are still a few spots around the edges, but those likely end up being cropped out anyway, so I'm satisfied with the results for now.
I wonder how well the Canon Rebel XTi sensor cleaning works in comparison. Getting out lint free cloths and swabs and locking up the mirror is a pain (and dangerous).
The unwelcome inhabitants on my sensor. I'm going to be buying a cleaning kit to eradicate these little fellows.
Fell behind on these. The EXIF on this shows it was taken on 01-Jun-2013 and adds a tiny bit more crud on the sensor from the last one. You'll have to look pretty hard to see the new spots, though.
Shutter actuations are at 5,065, so you don't have to go hunting the EXIF for it.
Minimalist I know. I think of an egg with a black "white".
This was a shot through welding glass held to the front of my 70-200mm lens. The full-frame sensor shows its disadvantage! No matter. I witnessed the transit though clouds hid the sun periodically so I'm happy I was able to get this much.
See you in over 100 years, Venus!
28mm wide, FF vs APS sensor - my 28-70mm f2.8 G lens is like 17-70mm lens on A700 or 28-105mm with A900. (Cool.. !!) - with f2.8 fix.

These diagrams are supposed to show why you need a small aperture when checking for dust on your sensor.
The vertical red line represents the sensor and the vertical grey line represents the AA filter. The black blob is a dust particle. The top diagram shows light coming in at a narrow angle, corresponding to use of a small aperture. The blue area shows the region that is in shadow at all angles, and since it reaches the sensor the resulting image will show a dark spot there.
The bottom diagram shows light coming in at wide angles corresponding to use of a large aperture. The green area shows the region that is in shadow at all angles. Since it does not reach the sensor the resulting image will not show a distinct spot from the dust particle. Some light can get around the dust particle. There will be an area of reduced brightness on the sensor, but it will not be as noticeable as it would be when the small aperture is used.
Agfamatic Sensor 100, Germany, 1971.
What must be the best, most minimalist case ever designed for a camera.
The Agfamatic 100 is a viewfinder camera for Pak-Film 126 cassettes. It has an Agfa Colorstar lens with fixed focus and fixed aperture. Two shutter speeds are selectable with the ring around the lens barrel, the scale showing a cloud and a sun symbol. The camera has a single stroke advance lever that advances the film, cocks the Parator shutter and turns the flash cube holder on which magicubes can be fired as flash. On the axis of the advance lever is the red "sensor", the shutter release button hidden under a round piece of red foil.
