RE_BEAM ROBOTS: Taller de construcción de robots
01.03.2014 12:00h - 16:30h
Lugar: Lab (1º planta / 1st Floor)
Taller de iniciación para la construcción de robots capaces de seguir la luz, utilizando en lo posible materiales reciclados (motores y sensores de viejos juguetes, aparatos, etc.) a partir de conceptos que electrónica analógica.
This was created for Flaghead Photographic at a recent Triggersmart seminar. The PIR sensor picks up on moving heat signatures so we dropped warmed up vegetables into a nice Thai bowl to demonstrate this function as we couldn't get a wild animal into the studio!
There's a blog about the seminar here - www.dephotographic.com/blog/triggersmart-workshop-decembe...
The sensor wand from BARS (Benthic and Resistivity Sensors) in the vent. A temperature of ~325 Celsius was recorded.
Look what I got in the mail today. An Analog Devices ADXL320 accelerometer (+/- 5grams). I also got 5 big green leds (10mm) that are extra bright. These will go underneath the monome. Now all that is left is a sheet of teak veneer.

Chris Berka: Lighting up
Chris Berka is CEO and co-founder of Advanced Brain Monitoring (ABM),
a San Diego-based company that develops wearable sensors leveraging
the lightest, most portable, and least invasive technology possible for capturing electroencephalogram (EEG) data, both in clinical and real-world environments. Berka has more than 25 years of experience managing clinical research and developing new technologies and is a pioneer in the field of accelerated human learning. Her work and research has shown applications for improved sleep, PTSD recovery, leadership, and military training on contracts and grants for the National Institutes of Health, National Science Foundation, Defense Advanced Research Projects Agency, and Office of Naval Research.
In 2010, the Real Canadian Superstore located at 2901 8th Street East replaced my favourite sets of automatic sliding doors from Gyro Tech with newer doors of the same model: the GT 1175 Whisper Slider. The new doors have one major issue: the Acusensor on the doors suck. For example, with this set of doors, customers with shopping carts won't see the door open until the cart is placed right under the Acusensor that's outside. The store should reprogram the sensor, or replace it entirely. What's more questionable is why the directional decals are placed on the outside of the doors... couldn't they have obtained decals that can be applied inside?

Check if your sensor needs cleaning: Set your camera to Aperture priority, at f/22, and take a shot of a cloudless blue sky (focus not important)... If you see specs, you need to clean your sensor...
There is a tutorial here: www.copperhillimages.com/index.php?pr=tutorials
(Yes, there is still a spec on the after pic.. I got it off, but was using white paper to check then, and I wanted the before/after pic here to be the same color)
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.

What better time to do another indoor test but during the weekly I-shoot-you,-you-shoot-me meetings.

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.

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.

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.
Happy New Year's Eve, with my best buddy JP. Taken back in 2009-2010 on 12/31/09 Drinking Champange while toasting New Year's Eve!

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.
