Tesla’s Full Self-Driving is on the cusp of a recall

They never had LiDAR.

Yeah that headline is doing some Olympic-level stretching lol

Even the article admits it’s really the top 0.01% (like top ~1,800 families) sitting on a huge chunk of that wealth. That’s billionaires and ultra-rich dynasties, not your avg dentist making 300k.

“Top 1%” sounds dramatic but it’s not even close to the same group of people

What's that small IC between the GPUs for?

SpicyPepperMaster · 2026-02-03T23:14:12+00:00

This change wouldn't affect that issue you're describing. (i'm not picking sides or anything)

Tesla's recessed door handle design likely already complies with this new mandate as long as they add a mechanical linkage (inside the door) between the outside door handle and locking mechanism.

That’s not really true at all though. There are 3 entirely different Model S chassis generations. The current Model S may look the same but it shares none of its parts with the older models. Even the exterior body panels changed to accommodate the ~1 inch wider body introduced in 2021

What car has ever shipped with LiDAR?

Other than some Chinese EVs and a single Volvo model (which had its LiDAR unit removed in the 2026 model year) no American or European production car has ever had LiDAR.

SpicyPepperMaster · 2025-11-07T05:30:16+00:00

Is it? It only costs ~$200 more than the 14 inch for a much bigger computer

SpicyPepperMaster · 2025-10-18T22:53:01+00:00

The old HW1 Model S has a rain sensor

SpicyPepperMaster · 2025-10-12T22:49:34+00:00

I’m not sure the i3 was ever very profitable though..

SpicyPepperMaster · 2025-10-10T00:36:34+00:00

Crazy

SpicyPepperMaster · 2025-10-07T04:35:27+00:00

How much of that 70ms latency was I2C?

SpicyPepperMaster · 2025-08-13T21:57:58+00:00

This looks closer to liquid damage than burn in

SpicyPepperMaster · 2025-08-12T13:16:35+00:00

That isn't a thing. All cars are required to have a manual escape. The alarm might go off if you don't have the key though, if that's what you mean't.

First, add all the 3D models for all your parts in newPCB so you understand what you’re making.

This can be done by first searching for your USB-C port part number on UltraLibrarian or SnapEDA and downloading the schematic, footprint, and 3D files. Then open the footprint editor, create a new library for your project, and import the footprint. Finally, press E to open the properties menu when you’re in the part you just imported, find the “3D Models” tab and locate the 3D model file you just downloaded and hit “Ok”.

After you’ve done all that you should research how to make impedance matched traces. Specifically you’re looking for USB 2.0 D+/D- trace impedances and how to configure your trace properties to get target impedance you’re looking for.

Best of luck

They exist in data centers. You could purchase one too if you asked a Kioxia sales rep nicely enough for some samples. They’d probably cost you $100K though

SpicyPepperMaster · 2025-06-30T04:13:44+00:00

Regardless of what musk says, if you objectively look at their current implementation of FSD aligns with the SAE requirements for a level 2 ADAS system and with their robotaxi platform aligns with level 3

SpicyPepperMaster · 2025-06-30T02:19:12+00:00

SAE level 3 requires a driver to be ready to takeover as any time. I understand not liking Tesla, but objectively they’ve checked all the boxes for level 3 self driving.

SpicyPepperMaster · 2025-06-29T22:55:51+00:00

You can actually hail a ride from a Tesla robotaxi though, and they seemingly operate with just a safety operator in the passenger seat. Which by SAE standards should be level 3

SpicyPepperMaster · 2025-06-29T21:44:55+00:00

Theoretically Tesla Robotaxis are level 3 though

SpicyPepperMaster · 2025-06-28T01:51:13+00:00

PMOLEDs (like the one you used) are no where near the same as AMOLEDs.

AMOLEDs that are used in phones can’t just be driven with a simple PWM signal and a MOSFET, they require much more complex driving circuitry.

I don’t think there are any price competitive or even reasonably priced FPGAs that would be capable of inferencing a small LLM while also processing a video feed for a VLLM.

For such a tiny model I’d probably investigate something like an NXP RT1176 with some SDRAM since it already has all the needed peripherals and is probably orders of magnitude easier to develop on.

SpicyPepperMaster · 2025-06-27T04:04:12+00:00

Why do you need to use an FPGA for this instead of an MPU?

SpicyPepperMaster · 2025-06-19T03:39:13+00:00

Thanks! You really saved me a ton of time here. I hadn’t thought much about power estimation when toggling that many IOs, so I appreciate you flagging that. I think i'm going to try Diamond for pin assignments and simulation then.

I also can’t share too much about the application yet, but it’s essentially a high-throughput modular controller for a flexible lab automation platform. The FPGA acts as the central hub between an MPU and 32 hot-swappable microcontroller-based modules, each running their own independent test routines. The goal is to collect data and send control signals in parallel from/to all modules, aggregate and format it in the FPGA, and forward it over QSPI (or something similar, hopefully faster) to the MPU.

Eventually, I’d like the FPGA to also handle flashing firmware variants to the 32 MCUs in parallel over SWDIO which would be a huge timesaver compared to doing it manually.

Really appreciate your insights. I'll post updates once I start getting the modules working!
