Baby's first unun!
My #AmateurRadio journey continues with making some of my own equipment...
I wanted to be able to connect either an EFHW or an EFRW to my KX3, but move the actual antenna away from the radio, so that I can POTA with other people close enough to talk, while keeping the antennas for the different out of each others' near field so they don't interere. To …

Partially-assembled unun. A nut on the upper right is connected to the coax shield, and is connected to a brass screw on the right for a counterpoise connection. A blue 100pf capacitor is in the upper left of a purple 3d-printed box, connected between ground and the center terminal of the input. At the bottom, the 6th turn is tapped and run to another brass screw which provides the 9:1 random wire connection. A strand of red magnet wire goes up to the upper left over the blue capacitor; it conn…
The internals of the unun with kapton tape covering the torroid, and the 49:1 antenna connection brass screw in the lid at the upper left.
The assembled unun with two wires attached. At the top is a wire next to a ground symbol on the side of the 3d-printed box. This wire is the counterpoise. On the lower right is another wire connected to the side of the box. This is the random wire connected to the 9:1 antenna connection. At the lower left, in the middle of the lid, is the antenna connection for an end-fed half-wave antenna.

Each of the terminals uses a heat-set insert as a finger nut to connect the antennas.

you've heard of chemists in the 30's
are you prepared for chemists in the 1830's?
moreover, bunsen himself?

History
Robert Wilhelm Bunsen coined the name kakodyl (later modified to cacodyl in English) for the dimethylarsinyl radical, (CH3)2As, from the Greek κακώδης kakōdēs ("evil-smelling") and ὕλη hylē ("matter").

It was investigated by Edward Frankland and (for over six years) by Robert Bunsen and is considered the earliest organometallic compound discovered (even though arsenic is not a true metal). Bunsen began studying it in the 1830s and had determined its chemical composition by 1843; during…

Maybe it wasn’t as fresh as the original #Connections, but I thought Connectin’ 2: Electric Boogaloo had some fly categories.

Así va mi proyecto de actualización del router WiFi en mi departamento. Tuve que "entrar a picar" para instalar un pequeño extractor noctua, muy silencioso, en la tapa de la carcasa. También hice un pequeño script para controlar la velocidad y así quede aún mšs silencioso.

Se observa un pequeño ventilador cuadrado de color beige conectado a la carcasa. Cuatro antenas negras están conectadas a la parte posterior de la carcasa. La carcasa está parcialmente abierta, mostrando el interior. Una parte de la carcasa superior se encuentra separada, mostrando una superficie negra lisa.

A while ago the media reported that most of the long-distance "suburban" trains between #Wrocław and #Poznań will be discontinued, and instead one will have to change trains midway. Irrespective of whether it's actually going to happen, let's consider it.
As you can probably tell by now, I'm not a stranger to changing trains. In fact, there are some direct connections that I do criticize. For example:
• Poznań — Szczecin — Świnoujście, where arriving at Szczecin Główny and turning back to leave the city is a waste of time. It's better to change trains at Szczecin Dąbie.
• Poznań — Krzyż — Kostrzyn, where instead of using a single railbus, you can use a larger EMU for the Poznań — Krzyż segment, and a smaller DMU for Krzyż — Kostrzyn (in fact, only recently the "direct" Poznań — Kostrzyn train involved just that, but it was supposed to be temporary).
However, good matches are the key. Say:
1. Max 10 minutes (when there are no delays) from one train to the other.
2. "Door-to-door" transfer — without having to carry all your luggage across platforms.
3. Reliable connection — if one train is delayed, the other train waits for it (or there are so many alternatives that it doesn't have to).
Can such a thing happen on Poznań — Wrocław route? I have my doubts.
I've been using these trains for years, and I can say this: there is no effort to match train from/to Poznań with other trains in Wrocław. Sometimes the trains depart 10 minutes before the first train from Poznań arrives, sometimes I need to transfer in 10 minutes, and sometimes I have to wait over an hour. And the same in the other direction.
Perhaps things would actually improve if the route is split. Perhaps people would actually care. Maybe even the trains would be fitted better to the timetable in Wrocław. But I find it hard to believe.
EDIT: One final thought — since there is no real reason to split these connections (except for profiteering), why make travellers' lives harder?

First crack at the SFP28 breakout/carrier module. Power and I2C are carried by the PicoBlade connector, high speed over the ARF6.
Single 4-40 mounting screw in the back for attaching to a standoff in the chassis, front side will be held by the front panel.

KiCAD 3D render of a PCB with a dual-height SFP+ cage, a high speed connector, a mounting screw, and a low-speed connector arranged in a straight line not much wider than the optic. A few not-yet-placed passives can be seen floating in space next to the board.
