Ridding DSLR Sensor of Stubborn Spot

I’ve had a stubborn spot on the sensor of my Nikon D7100 for awhile now. I could not remove it simply by blowing air at it.

I did some reading online (in particular this detailed article), and went out today and bought a pack of Sensor Swabs preloaded with Eclipse fluid. I was a bit hesitant, but followed the instructions.

The first swab didn’t do it, but a second swabbing appears to have dealt with the annoying spot.

Computer Getting Whiny

Fan noises on my tower computer have reached annoying levels, so I pulled the side panel and spent some time dusting with compressed air and a Shop Vac. The whiny sound has been cut at least in half, but it’s still noticeable. It may be time to try a new CPU fan soon, as I think that’s the one that’s most irritating.

It wouldn’t be too bad if it were a steady sound, but the fan responds to load, so it’s constantly rising and falling in pitch.

Hatchery Coho Smolts Die in Byrne Creek in SE Burnaby, BC

Well, I was hoping it wouldn’t happen.

I was hoping it wouldn’t rain, because rain flushes all the crap off our roads and into our creeks. Gasoline, oil, antifreeze, metals from brake-lining dust…

But today one of our volunteers from the Byrne Creek Streamkeepers Society observed 130+ dead coho smolts in the sediment pond, near where they had been released just two days ago. See photos in previous post.

Anger. Sadness. Frustration.

We’ve had years where we’ve counted over 700 dead smolts, or a mortality rate of over 25% of those released, and I’m sure we always miss many morts. Mother Nature cleans up damn quick when a smolt buffet is set for all the birds and beasts who love fish.

The weirdness is that indigenous fish appear to be fine. You’ll see fry and trout swimming about unaffected by the pollutants that kill the coho.

This one was barely alive. It sat on the bottom barely moving, then turned a few circles, and banged its head into the concrete wall of the sediment pond.
