It's failing storage, top half of the display is EXT4 complaining it can't read the SD card, bottom half is the result of that, services can't start.
My slurped machine needs an HD upgrade? But I just upgraded it dammit!

Bet you can play Doom on it

IDK but it's strange if true, because I'd say that a BSOD is more like a kernel panic? Obviously, I'm not an expert.
I think the idea was a visually easier to use for beginners info screen to help with diagnosing the issue but I never read too much into it

Esp32 probably doesn't have a bios crash. My bet is a raspberry pi
Not a BIOS crash but a Linux startup has been interrupted here. So likely you're right

This implies every drink and its display is handled by its own computer running linux. Potentially mtndew has a different IP than coca cola.

How often do they change flavors that they need a full blown computer to show the logo, probably downloading it from a remote server, compared to just a backlighted sheet with a printed image?

Idk, if they're plugging in one for each screen it sounds like a lot; there are libraries to do most of this. It wpuld only take me about a month or someone competent a couple days to write this. I kbow there's libraries to display, but i don't know what else this is monitoring/controlling. So that seems safe,
So there's a computer hardware cost that goes from ~5x(4?) Per machine to ~45x4 per machine. That's ~ 2 hours of code per machine difference that this would make, assuming you were paying ~80/hr to write it, which is reasonable.
Even assuming no code was needed for the pi, production takes twice as long as expected, and electricity costs don't matter (which, next to the condenser; they may not) you break even at ~16 machines. 20 if you want to throw in some other random arbitrary cost.
Even if you assune pi 0's, at, what 20/each? You still break even before 100 units.
So it would take less than a hundred machines for smaller chips to pay off. I'd believe an exec didnt (even ask someone else to) do this math, but how long have pi's had multiple video out's?
wrote last edited by [email protected]For an Esp32 you'd need to take a larger model which has psram. With the Pi, yes a is take a zero (Zero 2w or so). The Pi already has hdmi on board and a graphics chip and accelerator, while for the ESP32 you'd need a custom solution.
The price difference is maybe 10 Dollars per piece or so. On the PI I have 512Mb of RAM and what ever SD they put in for storage. On the Esp32 I have 8 psram or so and a tiny bit of flash.
Ah right, for the ESP i probably need to wire up a sd card, custom board, all that stuff, to just store that 24bit 1024x768bit image.
Naah, while I love my ESPs and am just build a project with one - the PI is just so more competent for this task while still being damn cheap.
A decent Esp 32 board is around Eur 5, a. pi zero 2w around 20. Compute module proably similar - customer prices.
That's a 15 Euro difference.
Ah and my developer pool who can code for Unix is a LOT bigger than the pool who have commercial experience for the Esp32.
I can't follow your math, at 100 units the price difference is 100x15 for me, which is 1500.- About a day of developing for a small team, if the office and hardware is free. More if you pay for those, too.
When I calculate, custom development always is more expensive.

Have you heard of this fantastic thing called advertising?

So working on ad machines before a lot of them connect to an external ftp site to pull down the latest version of the logo. Things like this you don’t care if it’s secure or not

Exactly. This implementation makes no sense. Unless the logos are animated, need to change frequently, or supposed to show advertising (I hope not), a backlit plastic label would do the same job just fine. In fact, that has done the same job for decades at this point.
wrote last edited by [email protected]This implementation makes a lot of sense if you think about the ability to support variable amount of screens without the need of complex routing and addressing.
It also has increased reliability where one failure doesn't break the whole system.
As for the need of it - well, that's "slurp" they try to sell some cold sugar to impulsive people who like flashy things. That implies animations on the screen and being "not boring".
The fact that they changed to screens by itself means that backlit plastic label was doing poorer job than this abomination.

Reminds me of a Rug Doctor rental machine I saw that was proudly displaying the default Raspberry Pi OS background and a login prompt

Is it just me who feels that having one processing unit per display is a waste?
I mean, I get it why they did it (it's way easier to just have one SBC per-display, both on the hardware and the software sides), but if designing such a system I would still try to come up with a single board solution if only because waste gets on my nerves.
