Cycplus G1: One year

One year ago, I mounted a GPS bike computer. It is a Cycplus G1.

My main purposes are GPS speedometer, GPS odometer, and GPS clock. It's OK. However, I would like the clock to be permanently visible on the status bar.

For the year, I rode about 4200 km on two bikes: first the Cannondale Cujo 1, and then on the Flyxii FR-701.

Another De Dion on EV

Here's yet another (see also 1, 2) example of a De Dion rear suspension on a modern electric vehicle (Daihatsu e-Hijet, also known as Toyota Pixis Van BEV, also known as Suzuki e Every).

This time, the suspension has coil springs and a Panhard rod.

"A city on the Angara river": Panoramas (2)

Two more panoramic images taken from the "Город на Ангаре" (A city on the Angara river) documentary.

Large lettering is visible on a building. The poor image quality makes it impossible to read. I don't remember exactly what it said, but I think it was something like "Путешествуйте по озеру Байкал" (Travel on Lake Baikal).

My first tubeless puncture

Some time ago, I got a puncture in the front tubeless bike tire (Maxxis Rekon Race 29x2.4[WT]). Unfortunately, the sealant didn't help because it had dried out (after several months). So, out in the field, I used a cheap tubeless tire repair kit:

It was easy, and the electric pump was very helpful.

I rode over 100 km with the "bacon strip" (the tire plug) without any problems.

Then, at home, I removed the strip and applied a tire patch.

Everything is okay with the tire now.

Five Star 500/8: Samples [2] - FF - f/8

Camera: Sony a7c (FF, 24MP)

Lens: Five Star 500/8 at f/8

The lens is difficult to use, but it was the cheapest option available some time ago. To achieve better results, the aperture should be closed to f/11, or even f/16.

Pentax Q7: DCP file for ART/RT (download)

I created a camera profile for the Pentax Q7 + Pentax Q 01 8.5/1.9 Standard Prime combination.

Download file (2026-08 version): q7.dcp (32KB)

This is a basic camera profile for ART/RT raw converters. It is only single-illuminant (D50) one. It only contains the Base table.

Input Profile (ART): Embedded

Input Profile (ART): Camera standard

Input Profile (ART): Custom: q7.dcp

Newly built cities of the USSR (1958)

I bought a collection of booklets from 1958.

The collection is titled "Новые города СССР/Villes Nouvelles de l'URSS" (Newly Built Cities of the USSR), and contains booklets about eight cities.

The booklet about Angarsk interests me the most.

Front engine transverse with RWD

In the ICE world, a front (front!) transverse mounted engine with rear wheel drive is crazy (like Ford's T-Drive concept). However, this engine layout is reasonable for a series hybrid, regardless of wheel drive.

There are several such rear-wheel drive hybrid cars. For example, Changan Qiyuan/Nevo A06 in EREV/PHEV version (source).

The front-mounted, transverse IC engine acts as a generator only.

There are no half-shafts in the front suspension.

The rear wheels are driven by the electric motor.

By the way, I would like the new Suzuki Jimny to be a series hybrid with a front transverse IC engine (for more cabin space).

Pentax Q 04 6.3/7.1 Toy Lens Wide: Samples [2] - 1/1.7" - f/7.1

Camera: Pentax Q7 (1/1.7", 12MP)

Lens: Pentax Q 04 6.3/7.1 Toy Lens Wide, f/7.1 only, without software cropping (29 mm equiv.)

Once again, the Pentax Q7 is better than the Pentax Q.

Expired Svema FN 32

Some Svema FN 32 (B&W, ISO 32) 120 film rolls.

All expired (develop before January 1994).

I have tested them. There are some visible spots in the shadows. To avoid this, a lot of light is required, so the film should be exposed as ISO 1 or ISO 2.

Wuling Hongguang Mini EV: Solid rear axle

The Wuling Hongguang Mini EV (electrical vehicle) has a solid rear axle.

Of course, it is not the first EV with a live solid axle. But it is still funny for a modern EV, even such tiny.

"A city on the Angara river": Panoramas (1)

Here are two panoramic images taken from the "Город на Ангаре" (A city on the Angara river) documentary. The quality is rather poor due to the quality of the source material.
