WTB Ranger 29x3.0

These are the new tires I got for my bike for the winter.




WTB Ranger 29x3.0 (TCS Fast Rolling Light), W010-0967, WNL1859. So called 29+ tires.





60 TPI



The recommended pressure range (1.4-2.4 bar) is rather strange. I expected lower values.




Weights (each tire): 1045 g and 1070 g

I liked the Vittoria e-Barzo Trail 29x2.6 tires for winter, but these tires are larger. Some time ago, I used the WTB Ranger 27.5x3.0 tires in winter conditions and was satisfied with them. I hope the 29x3.0 tires will be even better due to their larger diameter.

Pentax K 28/3.5: Samples [3] - 1/1.7" - f/3.5

Camera: Pentax Q (1/1.7", 12MP)
Lens: Pentax K 28/3.5 at f/3.5 (129mm equiv.)

Surprisingly, the lens works pretty well on such a small sensor. And while it is a wide-angle lens, it acts as a long-focus lens.

Film shooting (2024-2026)

I started shooting film again in 2024. After some experimentation, I kept four film cameras (135, 120, and Instax Mini formats).

Nowadays, however, I have sold all of my film cameras. I enjoyed the shooting process. I even liked developing film. But I disliked digitizing film (1 and 2). Also, film is very expensive for me.

So, now, I only have digital cameras. However, after this experience, I would like a black-and-white digital camera. I want a true black-and-white camera without a color filter on the sensor.

SZ Viewer A1: Build tool

The first time (since 2014), SZ Viewer A1 (i.e., the Android version) was built using Ant. Then (in 2017), I migrated to sbt with an Android plugin. This combination is very outdated nowadays and causes many problems with modern Android SDKs.

So, the next time I needed to increase the target API level, I switched to a build tool that I created. It is a simple tool for internal use only that calls aapt2/javac/scalac/d8/r8/etc directly. I did this to have full control without intermediates. And it works well. For me, it's a nice compromise, allowing me to keep SZ Viewer A1 compliant with current Google Play requirements.

Koozer 450 and Petro-Canada Peerless OG0 (NLGI 0)

I cleaned and lubricated the pawl mechanism in the rear Koozer 450 hub. I used Petro-Canada Peerless OG0 (NLGI 0) grease.




The buzzing sound became softer and quieter.

RoadFisher 55/8 (Nikon F): Disassembled

I took my RoadFisher 55/8 lens apart to adjust the focusing distance. Unfortunately, there is no focusing adjustment at all.




By the way, the aperture diameter (entrance pupil) is 5.5 mm, so the actual aperture is f/10 (as I expected).

Tonigy programming language (internally)

Some time ago, I began developing a new programming language. It is yet another one for the JVM. Yes, it's so unmodern, but it doesn't bother me. I currently use Scala and like it overall. However, Scala doesn't align with my personal preferences.

My language is very selfishly designed. It's a language tailored to my programming style. I only want to use it for my own tasks. I don't expect anyone else to use it. Perhaps one day I will release it as open source if it becomes quite usable. However, that is not my goal.

Internally, I call the language the Tonigy programming language. There was my project with this name in the past.

40-45mm lenses (2026-10)

These are my 40-45 mm focal length lenses.







Actually, the Mir-26B 45/3.5 is almost ultra wide angle (24 mm equiv.) lens for 6x6 film, but I use it as a normal lens on an FF camera.

The Samsung NX 30/2 and the Pentax Q 01 8.5/1.9 have shorter focal lengths, but they are equivalent to 45 mm and 39/47 mm, respectively, when used with their native sensors.

Fillmore tubeless valves: Leaking air

I recently noticed that a bike [tubeless] tire was losing air. The reason was a leaking Fillmore tubeless valve. The rubber part had swollen and could no longer seal properly.





So, I returned another tire valve back.

Pentax Q 03 3.2/5.6 Fish-eye: Samples [2] - 1/1.7" - f/5.6

Camera: Pentax Q7 (1/1.7", 12MP)
Lens: Pentax Q 03 3.2/5.6 Fish-eye, f/5.6 only, without software cropping (15mm equiv.)

As before, this lens is more useful with the Pentax Q7 than with the Pentax Q. Interestingly, the angle of view is too wide without software cropping, revealing some of the lens at the corners. Also, keep your hands away from the lens. Otherwise, they will be visible in the corners of the image.

The second image shows one of the buildings with large lettering that is poorly visible. It reads, "Наша цель - коммунизм" (Our Goal is Communism).
