it's 2025.. are there any serious EE designs that do not have microcontrollers in them?

Shaft from JLCPCB just arrived!!! Been printing the parts just to test fitment. All that's left is to finish the combustion chamber and liner. I've also managed to bump up the thrust to around 45N and dropped the RPM to just above 100,000RPM. Going to get it manufactured soon!

how did he know?
crazy how much ptsd there is in EE/hardware. i'm getting recs to add footprints for parts that don't exist in the project, putting unpopulated 0Rs all over the place "just in case". like naw dawg, i'll just make another board if things change that much.
homie doesn't know he has two hands
homie doesn't know he has two hands
bc i fucking put that E in swe lmao
hey new followers, i'm a swe by trade and last year I KNEW LITTLE TO NOTHING ABOUT HARDWARE. i'd done a couple arduino projects and modeled some cups and hooks in cad. you don't have to be an expert. i'm not. stop wanting to build something. just go build something dammit lmao
who wants to make a custom chip?
Day 5: Building a brushed DC servo motor controller. I've been refining the schematic more. I added a better reset circuit and ESD protection on the CAN bus (thanks @akohlsmith). Also some decoupling caps. I've ordered some dev boards to test this on breadboard tool.
here's the current state of things. if you haven't been following along, it's a brushed dc motor servo controller. i'm heading to bed. good night!
i figured out how to set the gpios too and found some more conflicts which are now resolved.

sora 2 is sim[n+1] don't forget to build for your own reality
i didn't know about cubemx, but it's great for working through all the quirks and conflicts that come up when choosing and configuring pins. thanks @_joel_a_
the STM32F*C8* has one PWM timer TIM1 and i just found out that you need to be careful where you hook up the thing that you want to control with that. in this case PA8/PB13 for the complementary outputs.
