Earlier quoted context omitted.

The PiZeroW is hits such an amazing triple point of price/functionality/size that although I love the Tinker Pro for coming close in size/price and the ease of Arduino programming for simple things the PiZeroW just gives you SO MUCH functionality.

Slightly off topic - The one-per-customer policy on the PiZero and PiZeroW seems very limiting to me for someone who would like to develop more than one pi-based hobbyist project (or multi-pi projects like a cheap kubernetes cluster to play around with that stack). Does anyone know if there are plans to drop this restriction anytime soon, or do hobbyists just need to accept that to do multiple projects they need to b…

I doubt that they can manufacture enough Pi Zero's to match demand without purchase restrictions. Not only that, but you also get people buying them in bulk and reselling them.

These things are a god-send for the auto industry in my opinion...specifically professional drivers. as a lead automotive mechanic for a semi truck shop, I bought about 5 pi's for our techs. We use them for reading OBD diagnostics and doing resets or long-term vehicle observation for certain problems. Theyre cheaper than most of the commercial rent-seeking computer tools we use and if a tech accidentally crushes one,…

What kind of software are you using for reading OBD?

Raspberry Pi is for hacking. It's not really a commercial platform. You can technically use it as such, but it's more cost-effective to design your own boards at that point.

That's true for the Arduinos of the world. But you need very very high volume to make designing a PCB with a complex BGA like the Pi worth your while. The industry standard is to use a system on module, and there are plenty of those from a long list of manufacturers. The Pi foundation has one too, what they call compute module.

The difference between Arduino and Raspberry Pi is already one where the Arduino (at least the basic, most popular(?) model) is just a board supporting a small, highly energy efficient microcontroller that you program in C, while the Raspberry Pi (even the Zero) comparatively uses a ton of power and runs a full Linux distro. That difference is huge, and seems to already be in the two different directions you're postulating.

That said, Arduino (the company) has released more boards with faster, more powerful processors over the years, and I wonder if they'll ever give up the flagship Uno model. I sure hope not, since as bjt2n3904 mentioned, it's a great stepping stone for small, cheap, efficient microcontrollers. It's kind of like learning a programming language and realizing how that knowledge applies to most/all other programming languages, whereas so much of the RPi is abstracted behind Linux.

Not OP, but I found this Python library for reading data from a car's OBD port that people seem to be having success with, including on the Pi: https://python-obd.readthedocs.io/en/latest/

This looks like the kinda setup:

Also a search for "reading OBD diagnostics with raspberry pi" brings back some promising results.

If the availability of the pi zero W is any indication I expect trouble ahead. Trying to buy the zero W in bulk through channels is practically impossible, and the vendors sell them only in kit bundles at many times MSRP at 10$.

Instead of the pi zero, check out the CHIP Pro ( https://getchip.com/pages/chippro ) ... a little more expensive, but available in quantity and designed to be pick & placed (or hand-soldered!), runs linux, and does most of the things a pi can do (sans video)

Stay away from CHIP, they appear to be bankrupt and/or fraudulent, they took my money and never delivered.

Their competitor, Libre Computer, has mused that given their investment in the graphics stack, they might be headed in the GPGPU / AI direction. Think Raspberry Pis that you can cluster together for deep learning, or individual boards that kids can tinker with to learn about AI. The blog post also predicted the 3B+ fairly exactly: https://libre.computer/2017/12/06/raspberry-pi-3x-raspberry-... Money quote: > We expec…

Please avoid code snippets for blockquotes. It's very annoying to read this with the `overflow-x: scroll` that HN's CSS adds (particularly on mobile). Just put a ">" in front of the paragraph, like so: > We expect the Raspberry Pi 4 to be based on a new Broadcom SoC based on Cortex-A55 built on < 28nm fabrication process. We can call this BCM2839 and it will feature the much alluded to VC5 GPU and a new form factor.…

I still struggle as to why this is still a thing on HN after all these years. Just link to a gist if you have code you want to share that is wrapping too long.
