Came home from work, realized I had about twenty minutes of sun to play with. Not really enough time to drive to some scenic location so instead I found a quite bit of street and just played with the sun.
Image sensor as picture object to test the resolution. The fine structure is ideal for measurements in sharpness of the reverse lenses.
I found the sensor type number on the chip:
Image sensor CCD KC73129
• Number of Total Pixels: 537(H) ´ 597(V)
• Number of Effective Pixels: 500(H) ´ 582(V)
• Chip Size: 6.00mm(H) ´ 5.10mm(V)
• Unit Pixel Size: 9.80um(H) ´ 6.30um(V)
IR sensor voor Fischertechnik kogelbaan. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik door de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt. Ook getest met de TXT Controller Fischertechnik en 9V voeding.

This is a prototype dual axis angular sensor with video camera that I made. Actually is just two linear taper potentiometers, a web cam, and some scrap plastic bent in to shape, but dual axis angular sensor sounds cooler
MOC: Sensor GTR. The front end is what prompted me to give it this name - I realised it bears a (vague) resemblance to the real Swedish Sensor GTR.
When the back gear is engaged on this style mill, the spindle normally reverses direction. This sensor detects when the back gear is engaged and ensures the spindle direction is reversed automatically so I don't have to remember it's running in the "wrong" direction and have to manually switch to reverse.
Sensor dust is a problem for people who have a camera with interchangeable lenses.
Especially lenses with a high magnification factor like tele and macro lenses show dust more clearly than you like.
To show: set your lens to maximum zoom or magnification, choose the smallest aperture possible (f/32), point at a bright even lit subject (blue sky) and take the picture.
Clearly this sensor needs a cleanup.
MOC: Sensor GTR. A variation of the theme from my previous Supercar - I wanted to see if I could build something a supercar that looked a bit more like it was meant for the road than for the track. Very happy with the result.
Connecting the logic analyzer again to test the radio communication stability. I'm trying to use SPI as fast as possible but going just a bit too fast sometimes gives strange results.
Sensors are critical for both everyday technologies like smartphones and also for scientists studying tiny nanoparticle formations. Many sensors work by detecting extremely small vibrations, using a device called an oscillator. Argonne scientists are experimenting with new ways to make even tinier oscillators—many times smaller than the width of a human hair. As part of their work, they created this computer simulation showing how a miniscule gold core inside a silver shell changes with vibration.

Lorenzo Moggio cleaning sensors as part of his regular maintenance for scientific instruments.
During summer aircraft take off on an almost daily basis. Concordia is a hubbub of activity as researchers from disciplines as diverse as astronomy, seismology, human physiology and glaciology descend to work in this unique location.
For the rest of the year, around 14 crewmembers remain to keep the station running during the cold, dark winter months.
ESA sponsors a research medical doctor in Concordia to study the effects of living in isolation. The extreme cold, sensory deprivation and remoteness make living in Concordia similar to living on another planet.

After Karate Kid's death, Jeckie began wearing a new costume and took on a new code name: Sensor Girl.

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.

Los domos de sal y glaciares salinos son una caracterÃstica común de la cordillera de Zagros. Los domos de sal son un estadio de los diapiros salinos. Los diapiros son una estructura importante para la exploración de petróleo, ya que la sal impermeable atrapa con frecuencia el petróleo debajo de las capas de rocas. (Wikipedia). Bushehr (223.000 h) se encuentra en la esquina superior izquierda de la imagen.

Microchip announced the combined analog and digital current sensor—the PAC1921. The new device is a dedicated power monitoring device with a configurable analog output that can present power, current or voltage. The PAC1921, available in a 10-lead 3 x 3 mm DFN package, contains a digital current sensor to maximize data and diagnostic reporting, while having an analog current sensor to minimize data latency. The analog output can be configured to represent power, current or voltage and can be adjusted for a 3V, 2V, 1.5V or 1microcontroller input. Simultaneously, all output values are also available over SMBus. For more info, visit: www.microchip.com/PAC1921-042915a
Using Adafruit PIR sensor and Neopixel 'thru' LEDs. The nice thing about the LEDs is that you get full RGB for two leds with one digital line. The LEDs are BIG and bright! The PIR sensors are really 'no fuss'.

Before and after pics from cleaning my D600 sensor for the first time.
I used Sensor Swab Type 3 and the Eclipse Optic Cleaning Fluid, both bought from Amazon.com

It took 4 swabs to get it 99% clean (3 would have been fine, but I was being OCD about 1 tiny spec). Here is the before and after in full resolution!
Shot with the Tokina 17-35, F14, ISO 800, 1/4s for all shots, around 17-19mm. AWB made the last photo a bit different colored, but you get the point :)
Total end cost to me was about $47, which is less than a typical shop sensor cleaning, and I still have 8 swabs left -- good for another 2 or 3 cleans hopefully!
I got hold of a little Agfamatic 200 Sensor in a charity shop, which had this Trueprint film inside. The cartridge has no date, so I don't know how old the film is, but these cameras were from 1972 onwards, so I think it is safe to say it has hung about a bit.
I processed it at home, using a Rollei Digibase kit, bypassing the bleach step, which is a good option for very old films and one can often get a monochrome image even if the dyes have all faded.
Half the roll was shot already - these images seem to have fared worse for the colour leaving not much intact. Those I shot have fared better but with some crazy shifts.
