Agfa Silette LK Sensor, introduced 1970, perhaps one of the last Silettes and an early Agfa with the red shutter release button. The body is based on the Agfa Optima 200 from 1968.
It is a low-budget camera, the lens barrel and the housing are made of plastic, though the top and the bottom look like metal. This camera hasn't a rewind crank, the rewinding is done by the advance lever, when the button "R" is tripped before, so the inner mechanism is complex.
The lens is a Color-Agnar 2.8/45 mm with three elements, the shutter is a Parator with 1/30 to 1/300 s and B. The Selenium exposure meter is coupled and the match needle is displayed in the viewfinder and on top, the ASA range is from 25 to 400 ASA. All settings has to be done manually, like on all Silettes, I think. The LK has a thread for a cable release on the backside and a hot shoe. There is no self-timer, no focussing aid and the frame counter has to be reset manually.
(If you want to remove the top plate: there is a third screw hidden in the hot shoe. The cover in the hot shoe has the most diabolic clip mechanism I've ever experienced.)
Cheyenne linemen install sensors on a lattice steel structure on the Ault-to-Hayden 345-kilovolt line. The sensor will measure conductor or static temperature, current, movement along every axis and the speed of the motion. Using this data, maintenance crews and engineers are investigating if spacer dampers on this line need to be replaced and if a different configuration may better prevent the conductors from hitting each other.

Today i took the opportunity to use a Sony NEX-7 [Crop-Sensor] with a Sony-Zeiss Full-Frame 35mm 1.4f lens.
I have recently read that using a full-frame lens with a crop sensor may not produce better results than using a lens designed from a crop-sensor camera and in fact the images will be less sharp.
When starting out, many photographers choose to go with a crop body and invest in full frame lenses. This is usually recommended as a good approach as you can keep your lenses and swap out your body for something newer down the road, eventually leading to that high quality full frame sensor that you always wanted. However some experts, especially Tony Northrup, claim that starting out with the full frame lens and crop bodies does not provide you with the sharp images.
In my case I had a top end full frame camera [Canon 1DSIII] with a set of very expensive glass and I was not at all happy as the combination was way too heavy and totally unsuitable for street photography. About five years ago I decided that I needed a better solution and after using a Sony NEX-5 for about a year I decided to purchase a NEX-7 and switch from DSLR to Mirrorless [at the time that was a big gamble]. In theory it would be possible to use my Canon lenses with the NEX-7 but in reality it was not a workable solution. The NEX-7 featured a crop-sensor so I purchased a set of suitable Sony lenses and they were not expensive.
My reason for getting the NEX-7 and associated lenses was greatly reduced weight coupled with the fact that my equipment did not attract unwelcome attention.
The NEX-7 performed way beyond my expectations and I was really pleased and then towards the end of last year because the camera was giving problems at random I threw all logic out the window and took an ever bigger gamble by purchasing a Sony A7RMkII full frame mirrorless camera which is larger and heavier than the NEX-7.
To be honest, there is no comparison between the two cameras, the A7R is very much superior and while it is heavier it is actually easier to use. Also the Canon lenses actually work with the A7R but using the necessary adaptor was a pain and added weight. However the Canon lenses showed what the A7RMkII could do so I decided that maybe I should consider getting some native Sony FE prime lenses and then I discovered that they all were expensive and heavy [ unless I got manual focus lens such as the Loxia ]. Anyway I ended up with a set of primes [and no cash] but I now have serious weight issue especially when I travel.
I was planning to use the NEX-7 as a backup or when I travel but the crop-lenses are not very good so it would make no sense to leave my full-frame lenses behind so a possible solution would to bring along one of the FE primes [35mm 1.4f] but then I came across discussions online claiming that FE lenses underperform when used with a crop-sensor. Of course there is another issue in that the NEX-7 is at the end of its life and needs to be replaced by something like the A6300 but as I already said I have no spare cash.

A close-up view of the light sensor employed by the phase detection autofocus system in the DSLR camera I took apart after its shutter failed. The horizontal and vertical rows of dark rectangles are the light-sensitive elements. Horizontal rows detect vertical edges in the scene, and vertical rows detect horizontal edges.
The 5 mm scale bar drawn at the bottom of the frame shows the size of the sensor chip. The resolution of the 4k version of this photo is about 3 µm per pixel.
Replaced the IR sensor on our 42" Vizio LCD. Turned out to be pretty easy to do and an cheap ($9) fix.

Using Arduino to get the cost of probeware down (for science education).
Vernier's cheapest interface is $61 and handles one sensor: www.vernier.com/mbl
Arduino Uno is $30 and has 6 analog inputs: www.sparkfun.com/products/9950
Our goal is to interoperate with this curriculum: www.concord.org/activities/research-focus/probeware
Build the other connector the same way.
Be careful, and think it all through. The male-female connectors have to match the male-female connectors on the bike's harness and the sensor.
And...the wire with the diode has to match up with the sensor's signal wire (black wire, of the sensor's 4 wires).
A simple, quick, and very cheap circuit to turn on an LED when it gets dark. Read more about this project here.
The O2 sensor connector is behind the starter, and for most bikes the starter must be removed to access it.
Before doing anything, disconnect the negative cable from the battery to prevent a short.
Top yellow arrow points to the power connection to the starter. This is live even if the ignition is turned off. After disconnecting the (-) cable at the battery, then disconnect this wire.
Middle yellow arrow points to a friction fit connector. Just pull it off.
Bottom blue arrow points to the O2 sensor connector.
This is a new textile sensor to measure water / wetness. It is 100% compatible with the Arduino platform. It detects water by changing its resistance from open circuit to a few megaohms.
This is the CCD sensor out of a Casio Exilim digital camera. The LCD was shot, and it was not worth it to get a new one. Plus it was more fun to take it apart :)
That's a pair of wire cutters it's resting on.
A simple heartbeat sensor for arduino. Communicates each beat to the computer via serial over USB. A little script in Processing sends OSC messages to SuperCollider which makes a sound. Processing also displays a graph of beats per minute readings from the Arduino.
This version sends serial messages over the USB connection, a later version sends OSC messages over ethernet (even cooler!) (http://www.flickr.com/photos/chuck_notorious/4041494889/).
Next step: use the Arduino Ethernet shield to send OSC messages directly.
Next Next Step: Use this as part of a cool multimedia performance!

This here I shot with my new Olympus O-MD E-M5 Mkii paired to my M. Zuiko 25mm (50mm with the crop factor). I shot it at ISO 100 || f8.0 || at a 3.2 seconds exposure......HAND HELD!
No post processing done either, from the camera here.
