       it is, dare i say, slowly getting there (MNT Reform Next motherboard version 4 with many things re-routed/re-layouted)

       btw why are electronics so complicated

       @mntmn electronics is super easy, if you can use bucket full of trained electrons. If you use the wild electrons then you can expect trouble. Those critters have a mind of their own.

       @mntmn Because at this point we're letting blood from the telegrapher's stone.

       @mntmn this, plus: why dense pcb layout, traces geometry, color pallettes are so beautiful? (in pretty much all eda software i witnessed)

       @mntmn I stg KiCAD diagrams look like magic spell language books to me

       @mntmn I wish I knew...It's silly I know, but I've spent 3 days trying to get a RP2040 and an ESP8266 to communicate via UART, and I still can only get it to work one way (RP2040 on the RX).

       @mntmn I really should invest in one,you're right...For now my best suspicion is that the ESP8266 3.3V is actually 3.37V and the RP2040s is actually 3.24V, but a level shifter seems overkill...The loopback connections do work for both of them, so that's something I've tired every combination of pull-up resistor, low baud rate and still nothing gets to the ESPI might try to connect their 3.3V together...

       @mntmn I work with dual core arm chip (one is m33 so security "features"...)Kinda missing pre trasistor era... Maybe not the scopes of that era... But the possibility to measure everything

       @mntmn so excited! Regarding the display, what’s the stats? I know 1080p and 12.5” but rest.

       getting even there-er! last polishing and checks tomorrow (incl. diff pair deskew) and then we can hopefully very soon build the 4th revision of this thing.

       BTW for some reason KiCAD is faster on my RK3588 Pocket Reform at home (where i did this in the last days) than on the i9-9900 at work (at least since I installed an intel GPU there when my radeon gave up)

       @mntmn Accelerated graphics/fallback graphics?Something I don't like about Mesa is that if you ask it "can you do this feature", it'll say "yep" even if the GPU can't but it can emulate it using the CPU; but this is almost always slower than the application's non-GPU fallback. So if an application uses a GPU feature that your GPU doesn't have, it's often faster to use "slow"/fallback graphics instead of "accelerated" graphics.
