Bought them at USD120.00.
Still in very good, like new condition, very little visible scratches.
This set is selling at close to RM600 new at the store.
Will let go at $250
I've been wondering for a while how dirty the sensor in my Canon 50D might be. After all, it's been through a lot, including a dip in flood waters and countless frantic lens changes in less than ideal conditions.
So, I took a shot at narrow aperture against a white computer screen, tweaked the levels in photoshop, and got my answer. (The dark streak at the bottom is a piece of hair in the lens, not on the sensor.)
Now, am I game to clean it?
If we learned anything at CES this past January, it’s that sensors are pervasive in every new cool tech getting to market these days. And health is definitely leading the way in this sensor proliferation. Constant tracking and monitoring through interconnected devices opens up unlimited possibilities for disease management and prevention leading up to new and remarkable business opportunities. Get the ins-and-outs of how these sensors can play to both individuals and enterprises and what companies are now doing with all of this data.
**http://summersummit.digitalhealthsummit.com/ - The Digital Health Summer Summit takes a deep dive into what it takes to build a successful digital health venture. It's a unique opportunity for entrepreneurs (and intrapreneurs) to hear industry veterans and key industry players share their lessons learned and best practices.

Despite its formidable armament, the Drifter remains primarily a research and scientific vessel, and sports a wide variety of sensors and gadgetry whose operation would bore to tears the average bystander.
The Drifter's main hull is draped with a protective layer of a composite ceramic ablative armor, which is designed to boil off into a harmless vapor on high energy impacts, such as mass drivers. While offering a fair degree of protection, the armor itself is high maintenance, and must be replaced at dock when damaged.
The ship also sports a gravitational diffusion field generator, which provides ample protection against most threats, but interferes greatly with the operation of the extremely sensitive precision scanning equipment, and most crews don't ever bother turning it on unless significantly outgunned.
Sensor size isn't the only variable between these cameras, but it's a big one. I did this test when I got the Sony for underwater shooting.
All five examples are 100% crops taken at ISO 400 and at F4 when the camera allowed me to specify. Light was fairly weak, so all shots were done on a tripod. Shutter times were from 1/8 to 1/30 second.
I used in-camera jpegs (the only option on several of these) and adjusted the color balance with a "WhiBal" card.

Race technology Hall effect sensor. It picks up the bolt heads on the propshaft and sends a pulse to the dash. It's quite easy to setup as the led on the back goes out when it senses the bolt head.
Acción BTL en grandes superficies.
IDEA.
Se colocaron sensores de movimiento en los pasillos, cuando las personas pasaban por la sección de cervezas este sensor se activaba y se invitaba a que la gente probara Redd´s con hielo
The sensor board and the battery pack barely overlap within the tube, so access to the serial port on one end and the battery pack on the other end is easy.
The surface was very easy to cut with a razor knife, and square holes for the buttons worked out fine. However, all the components fit a little bit too snugly for everything to really work properly. Most importantly, the servo ports are totally inaccessible when the box is closed, as the harness of any connected servo will crunch against the battery pack upon closing.
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.
