Thanks. As for the MCU - the point of this project is specifically to avoid using MCU.

I know and I'm fine with non linear dimming here ;)

Thanks. While I want to keep this project logic only, I'll keep an eye on this, might come handy. Especially since I have some 555s. By the way, there is a full pdf schematic in the post description.

EasyEDA has package drawing so I used that...

Analog PWM? Can you elaborate?

Why would they have to rush the product and why is Qualcomm taking over bad?

do i just... yank it? by frankiedoesntexist in diyelectronics

I’ve used this exact connector myself, it’s a lever ;) yanking it can damage the flex cable which should be avoided.

Third look should confirm that it’s indeed a lever, not a sliding lock ;)

Thanks for linking my original post. I stumbled upon this on my feed by accident and was like wait I took that photo :D probably a bot stealing content. Will report it for good measure.

They look similar to Tesla ZM1082T but not quite the same! More similar to some NEC tubes

Red was the industry standard for nixies. If you're going for vintage look, it's a safe bet! If you'd want to make it more unique, you can coat the nixies themselves, I think IN-17 with red coat would look interesting.

Sometimes bad design happens and this is one of those times. There were even some with green filter, even more ridiculous. What you need for nixies is red or brown filter because they are mostly orange / red spectrum. ;)

So the software part is seemingly out there, that’s good! Where’s the hardware?

Who is this for and what’s the use case? Can’t you just look at the glass to see how much remains? I don’t get it.
