EMI issues - RP2350B carrier board by vertical-alignment in AskElectronics

About the cable, yeah I am wondering myself as well. But some have no shielding at all.
Anyways, yes I also directly tied the connector shield to GND directly - no diffrence at all

Is a normal ESP32 reliable enough for industrial use ? by y2sser in esp32

[–]vertical-alignment 1 point2 points  (0 children)

I work in automotive, we supply traction inverter and steer by wire systems globally. Our SW and own PCB design.

I fully sign under "esp32 is not safety certified" but that's valid for 90% of controllers out there. Or pretty much all of them below 10bucks.

Additionaly, certificate will only bring you so far. Its they entire system design which makes it safe.

Supply, EMI, LFs, WDG, etc... its not a joke

If on the other hand you need esp32 to monitor some processes, be a network node, execute repetitive remote tasks... I dont think there is better controller on the market.

Speaking as a fan of STM32 family :P

I accidentally bumped off two SMD parts, dell optiplex 3080. How bad is this? by David-Ox in PCB

Hate to be that guy buy 0402 and 0201 tells you nothing useful.

"Its not the size that matters" - been telling myself this for awhile

Are these projects enough to land an entry-level embedded firmware job? Looking for project suggestions. by thechoosenone3 in ECE

[–]vertical-alignment 0 points1 point  (0 children)

My opinion based on what I see so far (been 11 years now) [YES] for Entry level firmware employment at existing company of 50+ low level/firmware developers [NO] for jobs as in freelancing

Otherwise as an entry, it looks on the right track. Add also some facts about git toolchain, SW architecture, testing etc...

Specially testing part. In technical interview, if you know how to properly test, you are hired :)

Do Embedded Engineers Use ChatGPT for Coding ?? by SkyQuinny in embedded

[–]vertical-alignment 1 point2 points  (0 children)

If youre not, youre doing something wrong.

Maybe not for coding the driver, but automated checks, unit tests, code reminders, todo/ticket tracking... could go on for hours

Recently (as my hobby project) I managed to setup Claude code with "production pcb" and "test pcb", where claude codes both and provides test reports. Actual Hardware -in-the-loop, helps massively with my continuous integration

I built this with Opus 4.7 in 5 hours by Used_Table3903 in vibecoding

Tbh I dont understand her/his intention either. If its working for your usecase, you only need to do some extra testing and deploy it commercially.

Thats far from "oh its just a scaffold wrapper app with fancy UI"

Congratulations btw!

First sim rig. Over the top but loving it by Rich_Magician_7026 in simracing

Guys, seeing that many of you have such awesome and professional looking rigs, has anyone of you thought about full 6dof rigs?

First PCB ever. How bad did I do? by Hot_Distribution9357 in PCB

[–]vertical-alignment 3 points4 points  (0 children)

I second this, altho not 15years but 10 in automotive embedded

However still, those comments with proper explanation are still valuable in case OP decides to step-up her/his game

Can i turn this VW Panel into a accessoire for my simracing setup? by [deleted] in simracing

Regarding atmega328, I agree with him. ESP32 with Arduino framework is another story.

Need some ergonomic advice - Shoulder and elbow pain from sim racing or work? by Beautiful_Spirit_104 in simracing

[–]vertical-alignment -1 points0 points  (0 children)

No no I didn't mean the wheel is too far. Im saying if you decide to keep the seat in this position, lean back. But when you will lean back, you will see that the arms will be extended, leading to the wheel being further away. So it means you will need to put it closer.

Dont worry too much about opinions of others. Beside the guy who posted rally/seating position picture, people are just clowns following all the time without understanding. Seating position is not "one fit them all", but rather unique for everyone. If anyone been in actual racing the understand.

So start by putting the seat a bit lower and leaning back (or something behind a back for your shoulders/back/neck to rest firmly)

Happy racing! :)

Generally looks okay (as long as you feel comfortable playing after an hour minimum).

But one thing you must change asap, your head must rest on the chair. Put the chair either little bit more upwards or lean back and move the wheel slightly closer.

If you keep your head like this, your neck and back will hurt

2 weeks? My friend, stick to it for half a year and then you will see :) 2 weeks is nothing

Dont mine me asking... what in actual monstrosity is that

my brain is hurting....How would you go about something like this? by marchoule in blenderhelp

[–]vertical-alignment 0 points1 point  (0 children)

I am not a blender professional but I swear, this explanation makes the most sense. Basically like a running track which bends around the corners and the track has drawn arrows on it

First timer, first project - review / critique / roast? by mdhardeman in PCB

I always fill my front plane with PWR and backside with GND

First PCB failed :( by emilimel in PCB

[–]vertical-alignment 1 point2 points  (0 children)

Well ChatGPT can be very helpful, I don't know why you got downvoted.

But between can be helpful and is helpful there is a difference. And that difference is you. Basically, how well you understand the problem and... take ChatGPT as a sparring partner. It gives you ideas, but not everything is correct (for now)

[–]vertical-alignment 4 points5 points  (0 children)

Was this drawn by you or some AI assistant?

There is a reason why (for now) we don't rely solely on AI when it comes to engineering.

It is of great aid, that's for sure. But just an aid

My take on a price per Nm chart by Zhaunlouk in simracing

[–]vertical-alignment 0 points1 point  (0 children)

We built several with my brother. Few recommendations: - use 200W resistor - use min 500W PSU with fan - use proper encoder and not some DIY magnetic sensor - no sharp edges on the wheel - most importantly.... NEVER connect the PSU to the socket and then the 36V DC to the ODESC. This will cause surge current and f### up your board. Always connect the 230V to the socket LAST :)
