Geht man nach dem IPCC, war zwischen 2006 und 2018 der durchschnittliche Meeresspiegelanstieg 3,7mm pro Jahr. Das mal Fläche der Meere (ca. 370 Mio. km^2) geteilt durch die Fläche von Frankreich (550 Tsd. km^2) gibt ganz vereinfacht:

Frankreich müsste 2,5 Meter pro Jahr absacken ⛏🕳

Ihr bedroht einen Einbrecher mit eurer Pistole.

Er bietet an, sie euch für 1.000 € abzukaufen. Als ihr zögert, bietet er 10.000 €.

Ihr verkauft ihm die Pistole, er schießt, nimmt das Geld und eure Wertsachen mit.

So ist es auch, wenn man Rechtsextreme wählt.

four nixie tubes showing minutes and seconds

Nixie tube clock works now.

I just need two more tubes...

Nixie tubes glowing in the dark

So far it's running great. I could finish the code, ordered a new revision of the pcb and need to wait for it...

Love the look already!

2. Got things mixed up with the nixie tube footprint: Thought that the pinout in a datasheet was top view but it was bottom... Well as it's THT I thought you could just switch the side of soldering.

Turns out: Works but now I can't show proper times as I don't control all of the cathodes AHHH

Transistors soldered properly to the pcb

Transistors soldered rotated to the pcb to get the wiring right

Some more issues with my nixie tube clock:

1. Messed up the connection between footprint and schematic symbol of the transistors switching the cathodes, had to get a little creative (see images, definitely IPC compliant xD)

Oscilloscope screen showing frequency of 3.2 MHz

Oscilloscope screen showing frequency of 420 kHz

So I've been building a HV generator for my nixie tube project but had a wrong resistor for the frequency programmig. The whole thing ran on 3.2MHz instead of 420k lol, suprisingly it still supplied the required voltage xD

Got the idle power down from 2W to a few mW

so I'm not sure which direction to read them, it's not very typical to have 5 rings in such order.
Colors are: Purple, Gold, Yellow, Black, Red.
Not sure with the yellow tho, may be brown or gold too. Do you have another angle maybe?

still need help with that?
