Can you use a proxy server to download the files?

I think so, I have a server which seems to have some external net access. It may have some things limited like it seems like it can�t access stuff on 443, so perhaps IT has restricted its ports.

VictualSquid: Feb 29, 2012; Gently enveloping the target with indiscriminate love.

In the old days it happened that labs got cds or dvds with linux updates in the mail, then installed them on a local repo server machine, and then you update your other machines from that server through the lan. I haven't actually heard of that done since before the first raspberry was built.
The capabilities are probably still there and inherited from debian to raspibian.
On the other hand that is how stuxnet got transmitted, so your IT might still not consider it acceptable.

All distros allow specifying any mirror you want for updates, it's not really a feature they have to maintain though it's just how the software works.

Most annoying part will be setting up your local mirror.

I wouldn't be surprised if some of them only allow http/https mirrors, though.

Mirroring can be pretty simple. Install debmirror, create a script to do the mirroring, and Apache/Nginx to share the mirror.

Here's our script.

LTT did a recent video on some good cheap alternatives to an RPi4. But what if I don't need all that processing power, any alternatives to the RPi Zero 2?

Or should I just get a beefy board and just run it really light? I have to admit I could use the extra USB ports....

Any time I've watched a video or read an article about Pi alternatives, there seems to be a lot more drawbacks than that ltt vid. It seems that they skimmed over a lot of the software/os issues.
I only half watched the video while doing something else though so who am I to judge eh?
It'd be great to have a wider selection of well supported options though. Maybe that'll be the silver lining after a multi year shortage

Radxa Zero and Banana Pi BPI-M2 ZERO are form factor equivalents. Radxa has a lot larger ram options and good EMMC, Banana Pi is basically the Pi Zero 2. Libre Le Potato that LTT covered is your inexpensive USB heavy option with the full size Pi footprint, the Zeros just have OTG ports that you can throw a hub on.

The fun part is finding out if it will work for what you need. Radxa works for Klipper which is what was important to me, but Klipper runs on basically anything standard linux, probably the same for the Banana Pi BPI-M2 Zero.

Yeah there's a lot of that and specifically "Good Luck" on a lot of guides if you use something other than the Pi boards that they seemed to just ignore and did a hardware comparison.

I haven't bought them from anyone except pimoroni or the pi hut (and at the time they were just bundlers, not outright scalpers). There's some super basic ones on amazon for $75 with no wifi or emmc with only 1GB:
https://www.amazon.com/Raspberry-Compute-0GB-eMMC-Heatsink-Connector/dp/B0B6VKYF58/

The one star reviews seem to be pointing out that they are low configuration models with nothing added. Since it's a prime seller you'd be able to return it easily if it had a problem, and they show it being available to deliver tomorrow to me (east coast US).

Yeah, I wanted a rpi4 for a low-heat desktop and, due to shortages and scalpers, ended up buying a refurbed Dell Wyse 5070 and sticking a bunch of ram and storage in, instead. They're thin clients, but will run Windows and Linux fine.

There's Pentium (mine) and Celeron variants but they're otherwise the same. It worked out so well, I snagged another to replace a rpi2 with increasing stability problems.

I have a Dell thinclient for an extra linux computer and it's a lot easier to deal with than an RPi, since it's is x86 it can run anything. If you don't need GPIO, an actual computer is usually going to be better than a pi.

If you want to do it really janky you could solder onto those pogo pins, or underneath them. Since that would damage a nice board, I'd probably get a piece of perfboard, make a hole in the corner that matches the standoff on that thing so it can screw into place, then solder some jumper wires on the perfboard that can plug into the header on the Pi (so whatever length you want).

I probably should describe my experience with the ZimaBoard:

Works great. Faster than the RPi4. I'm getting some stupid lock-up associated with hardware video transcoding so I switched back to the RPi4, which uses 1/3 the power to fail to transcode videos realtime the same way the ZimaBoard would fail to. But maybe I can get a newer kernel on it someday.

Anyhow if small form factor and low(er) power use is important, this seems like a totally workable option. Cruft recommended.

I need some help. A vendor sent us a prototype of something that's loaded on one of these:
https://www.newark.com/raspberry-pi/cm4008032/rpi-compute-module-4-8gb-ram-32gb/dp/40AJ6746

They also sent us absolutely nothing in the way of instructions. All we have is the device. So the first order of business is to make a backup of whatever OS image is already loaded. I want to do this before we even boot it up, so that in case we mess something up, we can restore it to the original state.

The problem is, I can't figure out how to mount the storage for external reading/writing. I've tried to follow this guide:
https://www.interelectronix.com/installing-raspberry-pi-os-raspberry-compute-module-4.html

I believe we put the jumper in the right place; and we connected the Pi's USB slave port to my computer and supplied power to the Pi, and I ran the "rpiboot" command on my computer. But all I get is this:

code:

RPIBOOT: build-date Feb 24 2023 version 20221215~105525 864863bc
Waiting for BCM2835/6/7/2711...

And the Pi's storage never shows up as a USB device on my computer.

Anyone know what I might be doing wrong?

I've worked a bit with Raspberry Pi's in the past, but they always had an SD-card. So I'd just remove the SD-card and put it in a USB SD-card reader, which worked fine. But this Raspberry Compute Module 4 with built-in flash storage is new to me, and I'm a bit at a loss as to how to work with it.

I haven't messed with every weird boot config so take this with a grain of salt. Also the information is a little confusing.
The second stage boot loader can be configured to check for usbboot or not, however this is separate from the nRPIBOOT gpio. So they might have disabled this, but it shouldn't technically prevent usbboot.

The first stage boot room is what checks the nRPIBOOT gpio, and can enter something called 'USB device boot' which I think is implied to be usbboot. But for some reason they didn't use the same language for it they used in the second stage bootloader. It also mentions 'recovery.bin' here and automatically updating the SPI eeprom which is kind of odd.

Also, if they enabled secure boot and burned the OTP flags you will not be able to do anything even if you get it into RPIBOOT mode, because you cannot change the EEPROM configuration and you cannot load the kernel for usb device mode into ram.

Good thread title

Trying to make a cat food control system because I have one cat who needs special $$$ food and two cats who LOVE special $$$ food.

Here are my two cats

Honda (the one who does not need the $$$ food)

Lucy (who does)

Based on the similarities in their appearance (or the state of individual animal detection), does anyone think it's feasible to have a RPi4 2Gb identify whether a given cat in front of a webcam is Honda or Lucy and then execute an action (basically activate a servo)?

My other option is to go hog wild with some frankenstein RFID system and see if a collar will work or pay to get a cat chipped.

Edit: Getting creative here, I could also put a reflector on a collar and it looks like I can scan a photo the webcam takes for that colour maybe using Pillow's ImagePallette module?

I don't have a clue about how well face recognition actually works on animals, but you could actually test it really easily. Take a few pictures of each cat, then use the command line tool from https://github.com/ageitgey/face_recognition and see how it does on a new picture not in the training set. If it does well, you should be able to wire up that library (or the Go equivalent https://github.com/Kagami/go-face if you prefer Go) pretty easily.

I petsit as a hobby business and have tons of photos of my dog clients, and Google Photos very frequently gets them all wrong. As in, they are identified as dogs in the photo, but dogs that aren't even the same colour will be tagged as the same dog. It would be great if you could beat that!
