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.

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?
Have you heard of this fantastic thing called advertising?

Esp32 probably doesn't have a bios crash. My bet is a raspberry pi
They are RPis.
I saw this setup at my local 7/11

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

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

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.

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.

Man it's so crazy how many small computers are around us. Just a few years ago that would have been a plastic label they swapped out when needed.
wrote last edited by [email protected]The difference in what can be done and the amount of work that needs to go into it between discrete digital electronics and just having a microcontroller or even microprocessor there is HUGE.
Also with microcontrollers and microprocessors most of the work moves from Electronics Engineering and circuit-design space to Software Engineering and software development, and the latter experts are easier to find plus the development cycle is way more friendly when it's just code which you can change and upload at will rather than physical circuits were simulation can only go so far before you have to actually create the physical hardware.
Even more entertaining, microcontrollers are so stupidly cheap (the most basic ones cost a few cents) that throwing in a microcontroller is almost always significantly cheaper than doing the control stuff with discrete electronics.
(For example a screen that size can be controlled by as ESP32 which if you embed it in your circuit yourself costs maybe $1 or $2, though that wouldn't be running Linux and programming it be much more low level, plus it's probably the cheapest you can go)
I actually got an EE degree back when we embedded circuits were just starting to be used so I didn't really get taught how to use them, then went for a career in software instead of electronics and came back to digital electronics years later and it's like night and day between the discrete digital electronics age and the everything is a computing device era.

You'd think a damn sticker would be good enough

My slurped machine needs an HD upgrade? But I just upgraded it dammit!
Anecdotally, a friend had a bunch of raspberry pis running inside specific devices, running hot, SDcards would eventually fail.
Started properly venting and cooling the pis... SDcards stopped failing (didn't have to be MilitaryGrade
either). -

You're forgetting the main driving factor behind being able to personalize a screen vs a plastic label: advertising.

supposed to show advertising
I'm betting on this.

Is there some version of Occam's Razor where "enshitification" is the most likely answer?

I've never seen one of these, but I assume it performs other functions - surely monitoring sensors, probably reporting that data, maybe allowing triggering maintenance functions, etc.
That said, processing and storage is so cheap on this scale that it's probably better (and cheaper) to go with a tried and true, widely supported system, than it is to optimize with custom hardware/firmware.
