Ohhh it works? 😯

4.96V is pretty bloody close to 5V considering this is just a breadboard and I've wired the switch and DC jack using just whatever the wiring that came with that electronic advent calendar is. Not actually soldered on, obviously. I reckon this'll be a solid 5V when it's an actual PCB.

Also I accidentally ordered the tiniest little switches and I'm not even sorry! 😆😁

In Physica B, we show that porous silicon acts as an effective compliant buffer for 3C-SiC/Si heteroepitaxy, improving crystal quality and enabling more reliable integration of SiC with silicon platforms.

The Nizhny Novgorod Radio Laboratory (NNRL).

Imagine it is June 1918. The young Soviet Republic, surrounded by enemies on all sides and struggling to find food for its cities, establishes a radio laboratory at the Tver radio station. The development of technology was necessary from both an economic and a political point of view.

But a small workshop with outdated equipment did not allow them to work at the required level. Therefore, it was decided to move the laboratory to Nizhny Novgorod.

The scientists at the radio laboratory worked on establishing vacuum tube production and developing radiotelephony.

Today, a museum dedicated to the history of the NNRL operates here. The museum’s exhibition contains many original devices and samples of radio equipment.

For me, this museum is a place where I feel inspired by human genius. I look at these tube assemblies, at the microchips, and remember the saying: “If aviation had developed at the same pace, today an airplane would be the size of a matchbox and could fly around the globe in one hour.”

URGENT UPDATE: BRYANSK KREMNIY EL PLANT DESTROYED Vlog 1344: War in #Ukraine

Ukrainian Defence Forces successfully demilitarised the #KremniyEl #microelectronics factory in #Bryansk with #StormShadow air-launched #missiles. Kremniy El is a critically important link in the chain of production of russian "high-precision" #weapons. The plant specialized in discrete semiconductor devices and integrated #microchips.

Just published: "Glaswelten", edited by Margarete Vöhringer and Christof Windgätter - a book on the materiality of glass in culture, history, art, and science:

I contributed a chapter about glass as a medium within media used in elektronics - from silicon to silicon dioxide to quartz glass.
