@byte_thrasher RC circuit on the pin, adjust the time constant, and measure the rise time to get the version number. Just make sure you take into account performance over temperature

I want one of my PCBs to be able to report its revision number to the MCU.
I can dedicate exactly one pin to this task.
What is the cheapest and easiest way to do this? Let's assume 20 revs (lol).
First idea that comes to mind is a simple voltage divider. Might be good enough

@blind_via @yacineMTB Every few weeks I re-download this app, see someone promising this, get excited, and then spend an afternoon watching 10 second clips of movies I saw 10 years ago. There are people on this platform but the platform itself sucks. See you all in a few weeks :P

Dear software guys who want a fun welcoming community to talk about PCBs, share, and learn together. We're building something special here, we'd love to have your follow along.
BlindVia@blind_via
Wait, software guys actually follow hardware guys because it looks like something they want to do? Bro, welcome aboard, I want to share my 20 years of hardware skills with you. All the old people doing PCB stuff are retiring, we need more PCB dudes! Please join me!

@yacineMTB You need to go deep on the VESC forums, there are so many iterations on there, you can outsource all that iteration

@83dollaroring @TokenOfTheMonth “unfunded” but often easily subsidized and paid via some part time instruction/research
English
@TokenOfTheMonth apparently purdue is an outlier for doing funded research thesis Masters’, which are basically just miniature PhDs compared to other schools and disciplines doing unfunded class-only MS’
engineering culture is also probably very different from conventional academia
English
Im curious
Sound off my PhD, MS and MBA mutuals id like to hear what you chose and why!

i had a lovely apartment with a view in seattle. but after my first was born it occurred to me that it was also across the street from a homeless encampment littered with needles.
so, i live in a small town in the country now

This sort of stat shows up in family’s exodus from cities and nowhere else. That stat can be argued as caused by cars based infrastructure or affordability, but as a high earner father I can tell you it’s exactly why I will never move back into the city.

Weekend assignment: drop your forever hype reel.
Mine’s a triple feature. Space Heavy demo, then our Varda capsule’s blazing return, then the iconic FF edit.
Somewhere out there, a startup kid is looping that and thinking, “Give me five years.”

@olegkutkov @Starlink There should be a version of the PCB that has no router/wifi, but does have PoE. Just swap it out.
English
A simple mod that adds Starlink PoE support to the @Starlink Mini terminal.
* New Ethernet transformer rated for PoE++
* Starlink PoE identification circuit with basic protection.
This allows to power and run Starlink Mini via a single cable using any Starlink equipment, such as Gen2 and Gen3 routers, and a Gen1 power brick.
Please excuse the crudity of this model. I didn't have time to build it to scale or paint it.

youtube will LITERALLY PUT UNRELATED SHORTS IN YOUR SEARCH RESULTS
that is INSANE

@jesx64 @yacineMTB I don't have a problem with spending a lot of time on my mobile tbh and the only social app I have is X But I like in-app blockers to eliminate any distractions, I don't want to search YouTube and get 100 slop shorts before any actually useful result if you know what I mean
English
just realized my pcba order has $140 in tariffs. that's 60%, collected in advance.
small-batch prototyping pcb assembly has terrible margins. But how are we supposed to build new things if we can't outsource tedious work?

@yacineMTB X shorts is no better. Click on any video in the TL and it begins auto scrolling unrelated slop in an attempt to lure you in. Add a setting to turn that off or you’re no better.
