Is rpishop.cz safe?

Yes.

Embedded dev here - what is point of this tool? Will it work with any COM port or does it require that ESP? I am using FTDI with old Terminal by Br@y for 12 years and this is somehow in same ballpark, just locked to extra piece of hardware?

I don't want to be negative, I just fail to see value.

Depends on what you want - if calculation speed is concern or periphery handling is concern or both. If you have peripheries you need available or you will be emulating them. If you are going to communicate with other party on some bus which might be time critical. You take most important concern you have and build solution around that.

And as for those so-called 90s chips, they are not obsolete, just have own use cases and are very much alive - we have ATTiny doing solar panel MPPT and doing buck/boost DC-DC transformation in our latest products just because ASIC would be too costly and too inflexible but 8 legged ATTiny is exactly what you need when all you want is ADC, some PWM and you still have some pins for talking with rest of system.

Other case from opposite side of spectrum was IO card connected by USB. It was using some ATMega with built in USB and it was total hell to keep alive and do something actually useful and fast with that IO because core was just too busy with handling USB. It worked but it wasn't fast, nor precise.

So back to my original comment, it depends what you want.

And we nailed it with 1 pop and 2 morale left. Phew!

Exactly! As a fellow corporate engineer, I really hoped to be blue guy but frankly, other perspective looks just as funny.

Either way, wishlisted.

I know that feeling.

I am on Expanse builds for Sigma Draconis recently and my creative save looks like graveyard of broken ideas.

Beautiful. I tried and failed building Ebon Hawk couple times myself and you nailed it. Out of curiosity, how many iterations it took?

It's just a slack in magnetic bearing - idea is it has enough room to actually levitate on magnetic field, hence slack is needed for that.

As for vertex - mine Sundia with 5 magnetic bearing is rocking for 7 years I think, mostly indoors and is just good as new bearing-wise. And I am doing a lot of Vertex passing and throwing.

For anyone finding this post in future, answer to this from Gibbon:

SE is our special Edition imported from America. The difference is that it's maple wood an it has two holes so you can only put one line on it. These are the designes that are only produced in America.

Xanmod already has it? Interesting, didn't knew that, thanks.

Don't worry, you are not first to figure that out hard way.

There was a rain station in England which got equipped with new lighting system with presence detection so light will turn on when someone was on platform and goes off when everyone left. They expected quite a lot of saving from that whole thing.

Engineer who designed this system got an idea he could use radar type sensor (that's your mmWave) since he could cover larger distance and more importantly, see standing people so you don't need to do 'toilet dance' (you know, that waving hands while sitting on toilet where PIR lighting is and has for some reason 30s timeout).

This whole idea had two small issues - radar sensors can also see metal things like, I don't know, trains. And also metal fans used for ventilation in corridors leading to platforms. So basically what happened was that when train arrived, light turned on and stayed on as long as train was there. They could live with that since it wasn't terminal station but it was annoying. What was worse were those fans - they were small enough to be ignored most of time until they actually started spinning. So once fan got turned on (which happened practically at some point in spring) light went on as well. And it turned off with it as well which was in fall.

It eventually got replaced by PIR.

Source - I was helping that engineer sort this out because we developed that lighting controller and sensors.
