Sensores de poluição do ar estão ajudando membros da comunidade em Portland, Oregon a combater os elevados níveis de poluição do ar. Seus esforços estão resultando em acordos com fábricas locais para reduzir as emissões na área.
This is a slight mod to the rig used by Starlight-Xpress. In this case the Camera is attached to a 2" nosepiece (or any M48 fitting) and placed in the Star diagonal. Placing the camera vertical allows the diagonal adjustment screw to take out all the slack so the camera can be rotated smoothly without any lateral movement. The laser pointer position is adjusted to maximise the parallax angle to the reflected return beam; this comes back past the laser and onto a wall (or other flat surface). The brightest spot should be, if the ccd has AR glass, the return beam from the sensor cover glass.
Rotate the camera in the diagonal and the reflected beam will describe a circle on the wall. Now adjust the camera collimation screws to remove any movement; I turned the camera till the one set of the camera adjustment screws was in line with the laser and furthest away from the wall. Adjustment depended on whether the laser spot needed to go up or down. If the spot was too high then the back of the camera needs to be raised slightly and vice versa if too low.
I used a weak laser beam of less than 5 milliWatt @ 532nm (green) to eliminate any chance of burning out any pixels on the sensor.
Note that this is the routine I used to adjust the sensor on my ASI2600MC and it should work on any camera but... you follow this description at your own risk.
SENSOR SYSTEM
MYSTICAL COMPUTER ENVIRONMENTS
A Mystical, interactive, aesthetic, computer experience.
The Sensor System was used as part of Padgett’s artist-in-residency at Loughborough University with the C&CRS for COSTART, partly funded by the EPSRC Grant GR/M14517 Studies of Computer Support for Creative Work, Artists and Technologists in Collaboration.
8 sensors are located on each side of a 365cm x 365cm frame at 30cm high. The frame is in front of a screen 245cm wide and 180cm high. One person rotates the shape and chooses the colour, one person walks in the frame and extrudes smaller basic shapes.
When people move in the installation squares are generated in the axis they move. Rotation is added and intergalactic patterns result.
This interactive work breaks down the subject/object dualisms as the participant is also the work. Participants move around a sensor system to produce moving abstract designs that are purely aesthetic and join 2D design with a 3D, mystical, inner space.
Después de un años de trabajo arduo, celebramos en compañía de nuestra familia en Cristo, sus grandes bendiciones durante el 2018.

Testing a different camera for the same board. I took this picture with the zoom at max and this seems to cure a lot of the lens distortion.
For this board I'm still waiting on some batteries, dual FETs and the RGB LEDs.
Sigh. Remember the other day I mentioned I had found some sensor dust on my D800. Well, today I got home, where I have the “industrial” size blower and I went to town on the sensor to clean it, and then my worst fears came true. It appears it’s not dust, it may be that sensor oil issue others have found from the manufacturing process (it’s believed the mirror or shutter action flings oil onto the sensor). So tomorrow I’ll have to take steps to get that oil off the sensor. Seems to be a common problem with Nikon’s pro SLRs so I’ll start with a Visible Dust wet cleaning kit rather than put my camera into Nikon’s service centre in Mississauga. Last time I did that with my D200 it took almost three months to get it back and I’ve got photos to take in the meantime.
The photo above is a composite from four images. I took the photos in sequence using the stop down and defocus technique for spotting sensor dust in between. I aimed the camera at my white drapes. Other than cropping out a 6 megapixel image out of the 36 megapixel sensor it’s unmodified from the camera. Yay.
Descripción: El hombre explora el lago del Abismo Anhumas, una cueva subterránea ubicada en la ciudad brasileña de Bonito. La cueva queda a 72 metros bajo el suelo, y el lago tiene más increíbles 80 metros de profundidad, aproximadamente. Gracias a la presencia del agua, la vida es posible en lugares inesperados como éste. Por la mañana la luz solar penetra a través de la única apertura de la cueva y adentra el lago, y la transparencia del agua permite la visualización clara del movimiento de las especies que allí habitan y también las impresionantes formaciones geológicas milenarias al fondo. La experiencia de la flotación en este lago me hace reflexionar sobre el poder de vida que el agua tiene, las posibilidades que ella da, y la extensión de la vida debajo de la superficie.

Blue thing is an infrared reflective sensor. We use the SuperPID speed control - it's very easy to use and reliable. After coloring the motor shaft with sharpies (half black, half silver), we can control the router spindle speed with precision! Ask Neil or Ted for more details

Bought (4) Infrared LEDs, a 9V, and a pack of Insulated Test/Jumper Leads, and a 9V Battery snap connector to do a quick mock-up of a Wii sensor bar. I mounted them inside some packing foam and wedge it onto my laptop LCD screen. The digital photo picks up on the infrared light. Taken with my camera phone.
