After years of putting up with dust spots, which show up as ugly grey smudges on photos of nice blue skies, I cleaned the sensor on my Nikon D70. It took quite a few goes as you can see. Each of the photos here is an out-of-focus picture of a blank white computer screen which has then had its contrast increased hugely (by doing "auto contrast" on it) to make the dust spots show up better. The little round spots are dust. The other variations and the larger, slightly dark areas are tiny variations in intensity of the LCD computer monitor which have been exaggerated by the 'auto contrast" step.
This thing is way cool. I started having dust problems on my 40D sensor so I picked up the Sensor Klear II with the Loupe combo. The Loupe is very useful tool, but also a fun toy.
Meet Jolly, a new addition to the toy family. He originates from a supermarket, as part of their campaign during the European soccer championship last summer. That's why he is orange and cheering. I named him Jolly, as he reminds me of northern star pics' awesome orange mug, who unfortunately has not had much coverage, lately
The reason Jolly is cheering today, is the prototype a Master's student has developed. It contains a sensor that a VIP (Visually Impaired Person) can point in some direction, and a row of Braille cells: the white dots. Depending on the distance of the nearest obstacle, the dots go up, to give a tactile clue of the distance. Slightly comparable to parking sensors in cars, but with tactile feedback. Today the student demonstrated it, and Jolly was mighty impressed.
An MCA Cat III Workboat, owned by Aspect Land & Hydrographic Surveys Ltd, of Ayrshire.
The 'Marine Sensor' is road towable, and with a small forward cabin, can deploy from a slipway or boat hoist / crane and able to operate a wide variety of sensors.
Her hulls and catamaran configuration lend a fast transit speed and give good directional stability resulting in high quality survey data.

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?

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.

Fuji X-E3 for sale - no LCD (EVF only) , sploge on sensor and no manual settings. Apart from that, it's perfect with only 2,700 activations.
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.
Salvaged from a broken olympus E510. The image sensor is mounted on a frame that can move on both X and Y axis to compensate the common camera shaking.
I noticed several spots on my pictures I took during my vacation, especially the ones with blue sky. Here's what the sensor looked like before I cleaned it.
Taken at F 32, 1 sec close-up exposure of my computer monitor on a full white screen, then adjusted level in photoshop to reveal the dust marks.
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.

The unwelcome inhabitants on my sensor. I'm going to be buying a cleaning kit to eradicate these little fellows.
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 Engine Control Unit (ECU) is a a small computer which monitors all engine sensors and controls all engine functions for fuel delivery, ignition timing, rev limiter, speed limiter, valve timing control and emission systems. This computer operates based on a set of values of which Nissan generated in their development process of the power plant, however, they left a lot to be desired by the enthusiast. The ECU upgrade
consists of the removal of the stock program chip and the installation of a socket which allows for quick and easy installation/removal of the EPROM memory. A new program catered to your vehicle's modifications is generated and installed.
Each of these programs have been meticulously developed on both the dynomometer and in real-world road testing environments to ensure that the vehicle performs as expected and with an adequate degree of safety.
Programming which allows for safe running of higher boost levels while maintaining "safety mode" configurations is our aim and no other company provides these "safety mode" mappings - something that leaves us scratching our heads even today.
Units receive thorough testing to ensure quality control. Boost jets are included for those without boost controllers.
** A $300 Core charge will be added to your order. It is refunded once we receive your working stock ECU back and it is checked. **
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).

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.

Image of my sensor just after a good cleaning (small spots are left, but it's not a problem for usual images). The darker parts on the corner are due to vignetting and not some kind of sensor dirt. This is perfectly OK.
To obtain such an image:
- Go to maximum aperture (f.22 or f.30)
- Adjust speed and take a white surface shot (long exposure is not a problem, if you move the camera when taking the image it avoid confusion between the white surface dirt and sensor dirt).
- Apply an auto-level on the shot, here is the result.
The the sensor before cleaning.
