Assembled AuroraWatchNet magnetometer sensor unit. The lower PCB is a Calunium v2.0 microcontroller board, the upper PCB is the FLC100 shield. This contains a Ciseco XRF radio module (blue PCB). The FLC100 magnetometer is located on a remote PCB (not shown).

This is our remote temperature and depth sensor. It's designed to be mounted on a bridge facing south. The solar panel and battery keep the system (in the battery box) up and taking temperature and depth samples. The idea is that we can measure temperature and depth in areas of the Hudson where the winter ice would destroy (utterly destroy) anything in the water.

This is a picture I created for the tfttf 48 hour challenge. Image sensors shot on glass and illuminated from above and below. These are CMOS sensors made by Omnivision.

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!

It was a clear day and I had meant to do a dust/oil sensor check anyway, so f/16 + focus to infinity + point at the sky and here we are. Shutter actuation count is 3,585 so I'm above the anecdotal 3,000 shutter releases when the dust/oil problem is supposed to go away or be reduced.

 

There is visibly more dust on the sensor now than there was on the last check, although it's still not bad and mostly in the upper-left corner. I have been swapping lenses quite a bit lately, too. I might try to do a sensor clean soon.

Fujifilm XE-1 with 18-55mm zoom in downtown DC. I can't get enough of these old houses in the District. The fuji 18-55mm zoom is as sharp, contrasty and free of distortion as any Leica, Voigtlander or Zeiss prime lens that I've ever used and the X-Trans sensor in this camera is magic. I kept the Velvia jpegs for most of these shots but found the raw files more useful in extreme situations. Once again, 80% or so of the jpegs were good enough and it wasn't worth fiddling with the RAW files unless I needed to pull detail from extreme high contrast shadow areas.

The now-defunct Pentax Q mirrorless camera system was a miniature marvel, squeezing image quality rivaling DSLRs out of petite pocketable units featuring the tiny sensors usually found in feature cameras.

 

My favorite of the bunch is the Q7,in my opinion the best balance between imaging power and ergonomics. Paired with the fantastic 01 8.5mm standard prime lens, it makes a great compact walk-around kit that is light, unobtrusive, and most of all, tiny.

 

I haven't gotten to spend as much time taking pictures recently as I'd like, but when I went to visit relatives over Easter weekend, I stuck this combo in my jacket pocket, hoping to squeeze a few shots in if I got a chance. That morning, I took a quiet 20 minute walk through some of the surrounding wooded lots looking to capture some interesting high-contrast textures. Here are some of the results. Nothing too fancy, but a reminder of why I enjoy using this combo so much.

Pacific Northwest National Laboratory developed sensor-packed synthetic salmon that are making their way through the turbines at Bonneville Dam and other hydroelectric projects to measure the conditions that real fish encounter as they pass through turbines at hydroelectric dams on their way to the ocean. The information they collect could lead to more fish-friendly turbines in the future.

An Old, Used Canon Camera I Once Tested.

My prototype temperature sensor at work in my office, while my $6.00 cast iron chicken looks on. This board automatically posts the temperature to a mySQL database, and its associated webpage displays the temperature over time. Story of what it does is at... http://www.ka1kjz.com/861/temperature-webpage-update/

I wonder if the last step in the instruction video is correct? :)

Three rate gyros, a 3-axis accelerometer and a 3-axis magnetometer (compass). The ultimate goal for my new KAP rig is to have a stabilized camera platform referenced to the local geo-spatial coordinate system.

 

Look out, I've got digital sensors and I'm not afraid to use them.

Saarloq es una localidad en la municipalidad de Kujalleq, al sur de Groenlandia, ubicado exactamente a 60°32′N 46°03′O, a unos 20 km de Qaqortoq. Tiene una población de 50 habitantes. (Wikipedia)

En el mar de Labrador, al sur de Groenlandia, se forman estas revueltas corrientes que parecen formar borrascas. Pero estas corrientes (de color azul intenso en la imagen) se hallan en la superficie del mar. Las nubes se ven en color blanco, como las que aparecen a la izquierda en la imagen. Este color azul representa zonas nevadas sobre tierra firme, como en las islas que se ven arriba y a la derecha en la imagen, donde se encuentra la citada localidad de Saarloq. Supongo que en el mar se trata de aguas muy frías, con temperaturas cercanas a la congelación.

 

Saarloq is a settlement in the Kujalleq municipality in southern Greenland. Its population was 21 in 2020. It is located on a small island with the same name off the Labrador Sea coast, at the mouth of the Qaqortoq Fjord, west of Alluitsup Paa and 20 km south of Qaqortoq.

The settlement is the southernmost of the three settlements—along Eqalugaarsuit and Qassimiut—that made up the former Qaqortoq municipality. The settlements are presently governed by a joint settlement council. (en.wikipedia.org/wiki/Saarloq)
