The sensor wand from BARS (Benthic and Resistivity Sensors) in the vent. A temperature of ~325 Celsius was recorded.
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.

Offshore Technology Conference (OTC) - May 4-7, 2009 - Houston, TX: Sensors used in deepwater drilling are tested at FMC Technologies' Subsea Technology Center.
These guys from the University of Louisville make water sensors (http://makerfaire.com/pub/e/4015). I thought about telling them to try the Bernoulli effect, but why? I noted they were using TI MSP430 microcontrollers.
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.

Not really sure what's up with this, but the first time I popped on the 8mm fisheye (which is for APS-C crop sensors) on a full frame body, it was instant fascination.
It could be just me and the time I happend to use it in first (pretty rememberable!), but seeing the shade the hood casts (outlining what the DX sensor takes), removing it and getting the sensation of the actual image projection, at least part of it: a 180°+ angle of view, with often sweet artefacts to the rim. Tiny rainbows, orange and blue casts etc.
It also gives me the feeling of 'looking out from somewhere', into the landscape, rather than seeing like I'm there.
Could also easily be a case of gained freedom due to limitations; I mean a significant part of the image will be black with this setup, plus the ultra wide angle fish-eye distortion on top of it.
In that sense it comes natural to 'just play', without expectations. Can anybody relate to this? Yet this does not necessarily mean that the resulting images lacks impact per default, at least I think so.
Anyway, I dig the shots of this series, the development (a bit vintage-y) and the summer vibe it gives me of the time this took place. Perhaps some of you enjoy them too..

The unwelcome inhabitants on my sensor. I'm going to be buying a cleaning kit to eradicate these little fellows.
Golden Tours of Alperton (115, BF63 HDH) at Duncannon Street, Trafalgar Square, London. Body no NB564, delivered new 15/02/2014. Apologies for the mark on the left hand side of the photo, caused by a clump of sensor dust that got into one of the filters in my camera lens.
Ahh! What's this thing on my head!!! Oh, a sensor to calculate body core temp and circadian rhythm. Phew. Credit: Chris Hadfield Twitter account
Sensor dust before cleaning, only the two very obvious spots (dot lower right and hair lower left) showed up at other apetures in blue skies and such. To make the sensor dust more clear I upped contrast a lot.
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).
Using a regular Arduino board to do the testing. An Arduino Mini Pro will be used in the final version.
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.

The Panasonic lens has two lenses that are fixed focus and fixed aperture (F12).
The lens has been modified with rubber washers toincrease the distance from lens to sensor, i.e. to focus closer. One of the rubber spacers can be seen in the left-hand picture just beneath the word Lumix.
The M4/3 lens is held on to the Sony E-mount with some small dabs of Blu-Tak, and. the lens hood helps shield against stray light getting in to the sensor.
The focus distance of this set up is approx. 10cm.
