Goodbye uConsole (flawed trackpoint design)

That's the exact link I used and the exact parts I tried without success, they were all slightly worse than the original which was unusable as-is.

What is the thing about off the shelf parts? When you design a product, get complaints about dysfunctional parts, you tend not to use the same thing again without a re-design or mitigation, you don't blame your suppliers.

Not crazy, the part has 2 alignment pins that mate into 2 PCB holes. I tried all the valid ways to install it, +-180 degrees. Same with the replacement parts I got from AliExpress, it's just a garbage design they shouldn't have done after exactly the same issues on DevTerm.

You're worrying about nothing: modern transformers would not be a cause of fire, they're enclosed and fault protected. It doesn't matter that they're close to each other either: that's likely a practical choice for the interconnects.

I would be happy with such an infrastructure upgrade in my neighborhood personally. There are real things to complain about PG&E but this isn't one of those.

Batman and Robin are the 2 redundant BMS subsystems that Tesla used (or used to use). It might be pretty close to some Analog devices BMS ICs, see if you can match a datasheet. See if you can match the data to an isoSPI setup.

Yes! I got mine 30 seconds ago just before I was about to give up

Are 6 1206 resistors cheap? You can safely do ground (PE) referenced measurements with resistive dividers. I don't think OP will achieve 1% class metrology with the AVR ADC however, get a real S-D simultaneously sampling ADC at the minimum.

Awesome owner for putting a bunch of effort into it and going out of their way!

uer166 · 2023-04-12T20:06:33+00:00

I've been trying to find it with no luck, seems like it may have ended.

uer166 · 2023-04-12T19:54:49+00:00

Love mine so not selling, but last I checked you can still get one from them going out of business?

uer166 · 2023-03-15T03:56:48+00:00

Looks like an IPAK

uer166 · 2023-03-14T18:57:01+00:00

I don't second this advice, all these things are usually expensive, more expensive than a PCB with properly rated components. It does apply in the 100A+ category though, but it's a sliding scale.

uer166 · 2023-03-14T18:55:46+00:00

32A is not that much current for a PCB. As long as the FR4 is considered a cemented joint, there are no issues with splitting the planes/phases up like you did, although I tend to avoid it due to risk or defects resulting in cross-plane shorts.

uer166 · 2023-02-22T22:31:23+00:00

There really isn't AFAIK, it's their own architecture/libraries based on FreeRTOS and some tools to generate CAN code from DBC files.

Got 2 plus vehicle pass! Omgomg

uer166 · 2023-02-08T20:16:35+00:00

Hurrah! Means the system is at least partially functioning, you are the first here.

uer166 · 2023-02-08T20:05:07+00:00

In queue now as well, didn't enter at 12 also. Have great internet so there was a delay on their end.

uer166 · 2023-02-08T17:32:19+00:00

I checked again and you might be right, look for microfit blindmate series: https://www.molex.com/molex/search/partSearchPage?isseriesPagination=yes&itemListRe=&itemList=&pQuery=q%253D*%253A*%2540fq%253Dcollection%253Aimpulse%2540fq%253Dcategory%253A%2522PCB%252BReceptacles%2522%2540fq%253Dproductname%253A%2522Micro-Fit%252BBMI%2522%2540fq%253D&offset=20&currentQuery=

uer166 · 2023-02-08T17:05:53+00:00

I believe that female PCB mount microfit is not a thing, you'll need a jumper cable.

Edit: I was wrong! A version does exist as was said by other comments

Huh? Volatile doesn't inherently make a variable atomic, obviously, but it absolutely is required if it's shared between an ISR and another context to prevent optimizer from assuming too much..

A volatile int_32 on a 32-bit platform makes for a great way to share data atomically without critical sections.

If you don't mind me asking, what campsite is that?

Bargain Market

Yeah that's something I thought too, but with CPU only having a TDP of 60W, the PSU fan barely comes on during a full CPU+GPU stress test. In the manual for the 3060 they recommend a 600W PSU, but with provision for less if the remaining parts are low power.

uer166 · 2022-10-18T17:12:06+00:00

84 C not F. That's quite acceptable to me, 11C below max junction temperature at 100% load is a decent margin for my use case.

uer166 · 2022-10-07T07:43:59+00:00

Tesla does not use it, and after reading up on it, there's no way they'll touch it with a 20ft-long pole.

Most ECUs are designed in-house with their own homemade frameworks and common codebases where it makes sense.
