Must fight temptation to buy an overpriced raspberry pi
-
Not the person you're asking but personally I use Jetson nano for some work stuff (and when I upgrade the "old" one is mine), odroid I've used for some misc creations and testing, and I'm personally looking forward to trying the radxa x4 as an htpc.
What I am really excited about right now is tossing my recently acquired spare jetson nano on a drone, right now I'm setting it up to walk around with it and test CV before it gets mounted up on the drone.
Will you use a separate flight controller chip or try to do it all on board?

There is quite a range of devices out there now with varying capabilites. Things like the Onion Omega2+, Oranage Pi, and more.
Raspberry Pi also remains good. While the Pi5 is expensive and more powerful - raspberry pi also makes the Pi Zero boards which are cheaper less capable boards which are closer to what the original raspberry Pi was but newer hardware.
I'd say the Pi5 is a heading more towards a full PC like device (hence the comparisons to cost and capability minipcs pepple are making in thia thread). But there remain plenty of lower spec machines out there now similar to the original cheap Raspberry Pi concept. And we've had high inflation recently - to some extent the cost perception avtually reflects money being worth less than it was and buying less for $10 or $20.
Yeah, the Pi moving to full computer thing is weird because the SD card is still a massive bottleneck on normal day-to-day usage.

Going separate for now, maybe later I'll go for all on the same

Power consumption is a massive reason to really not do that. Its cheap for a reason, its takes a shitload of power to be shit and you will pay more in energy than you save in hardware unless its only powered on for short periods of time - a server typically isn't.
This is actually something that applies to cheap products too. Was in Asda a little while ago and saw 2 LED bulbs with the same lumen rating. Cheaper one used 3w more and you only saved £1. Running it for 8 hours a day for a year would cost double that saving in electricity. For a server you are looking at almost £2 per watt each year. Does that ewaste look so good to you now?
Some things are absolutely worth getting second hand, but you really should be careful considering the power cost as well.
Quick edit: If you don't need it running 24/7, consider something like AWS too. I love selfhosting but if its not running much it might be cheaper to not bother buying hardware.
these shitty win8 laptops are surprisingly low power and efficient though.

The post is talking about RPis and other SBCs. Mini PCs are in a whole different category.
Yeah, but this is about self hosting and it's costs, so the comparison is relevant.

I think this really depends on the model they're eyeballing because the Pi5 is frankly ridiculous for the price and has absurd power requirements (5V5A USB?). I wouldn't recommend one of these unless you have a specific need like a certain hat or the GPIO pins. You can get a Dell micro Optiplex for less money and have a full fledged i5 or i7 processor with similar power usage.
Plus the RPi Foundation exposed themselves as the greedy bastards they are during COVID which is yet another reason to turn your back on them.
For something like a Pi Zero, maybe go for it, but there are similar devices out there from other companies too.
wrote last edited by [email protected]I picked up a used 2018 Fujitsu office PC with an i5-7500 for $60 (from a physical recycle shop, with a 14 day warranty) and it draws 15W idle. Way better value than a Pi (once you've added case, cooling, PSU etc) for running home server stuff.
A Pi still kills for "Arduino plus plus" use cases where you need the size, GPIO or can optimize the heck out of power usage on a battery.

This is generally not true. If you are using your laptop as a home server chances are it's going to be idling 99% of the time and laptops are generally pretty good in terms of idle power draw if you manage to disable the screen (or just disconnect it, take it off and find a way to repurpose it)
And in terms of environmental impact saving a laptop from landfill is definitely better since the majority of a computers impact is from the co2 emmissions from the manufacturing process. And this isn't taking into account the likely ethical considerations such as supporting terrible mining practices for resources like cobalt.

Everyone here thinks their shit tier 2018 laptop is made of gold or something.
Yep. My FB Marketplace is 75% crackheads flogging off stuff they stole from shops/actual tax payers/their neighbours/ the train, 10% delusional idiots with shit that isn't worth half of their asking price, 10% scammers, and 5% not shit listings.

Get them from where? I always read about these basically-free computers but have yet to see one
I do e-scooter mechanical stuff, I always have a bid war with the local franchisee scooter shop nearby fighting for the scooters. I know its them, so I try to raise the bids for them as much as possible to fuck them around.

It's been a while but I remember Orange Pi having terrible support? I haven't heard of the others.
Whereas the RPi has the amazing compute module if you need it too.
Sometimes paying more is better.
Oh, for sure. It depends what you need it for. A lot of people just want a pi for something like a pihole or a stats dashboard of some kind (that's my use case, anyway). You get what you pay for and sometimes you've gotta pay for what you wanna get.
-
Are you living on a space station? What is this shitload of power? A whole 60 watts? Are you rationing AA batteries to run your household?
What is it with the bullshit fanciful rationalizations people come up with to consume consume consume?
And that's 60W while charging. In idle with the screen off, low end laptops often consume as little as 2-3W. Which is not far off from a pi.

damn you all, now I impulse bought an old thin client for 30EUR
but, fwiw: I mostly use RPi for my purposes, up to RPi4; RPi 5 I think missed the mark, with its active cooling requirement and power use. (and price...) the only use case where an i86 alternative is justified is my jellyfin setup (where realtime transcoding is needed). -
A raspberry pi is not as efficient as people are claiming. They need up to 25W PSU for a reason. Laptops can idle lower than that certainly. Something like a MacBook Air M1 would idle in single digit territory, as would any netbook basically ever made. Only really high performance or older laptops have idle power draw issues since battery life is a major selling point of a laptop. Said laptop is probably also faster than a raspberry pi. The people building Pi clusters are really not doing themselves any favors with power efficiency.
Nah no way does the average ewaste tier laptop use less power than a raspberry pi for any given task. The power consumption floor for a laptop may be lower than the rpi ceiling but that's not a fair comparison

And for some (including me) that's our only computer (other than phone). I just can't afford anything, so all I have is a shitty laptop from 2010 that barely plays 1080p video. I deeply want something better, especially a steam deck, but doesn't look like that'll happen anytime soon (or ever).
And then you see people have steam decks that just sit there, unused, gathering dust.... fuck.Consider buying used hardware from an office. Lots of places sell used gear for dirt cheap. A used office desktop with a used GPU from the last 3 years or so would be a massive upgrade without spending much.
Steam Deck is still a good deal for what it is though, but I wouldn't use it as a primary workstation.

Ewaste computers actually tend to be on par if not better than an RPi in power consumption these days. It might feel like a RPi should be more efficient given the size and USB power connector, but modern Pis consume a solid 10-20w while in use which is more or similar to most miniPCs (they idle at single digit watts now and can "race to sleep" more effectively than a Pi) while costing about the same and the Pi is far less upgradeable

Yeah... I'm not going to stick a clunky old laptop on top of my bookshelf and have it run 24/7 as my PiHole. My Pi Zero 2 W is far more appropriate.

I'd happily send one for the cost of shipping

Laptop chargers are no fire hazards anymore than raspberry pi PSUs are. In fact probably the RPi parts are worse as they are built down to a cost.
I would assume that landfill laptop manufacturers are trying to minimize costs even harder on the charger.
but what timeframe do you mean with "anymore"? laptops made in this decade, or the last 10 years, or something else? there's plenty of old laptops that fitinto OPs category.

Laptops don't even use that much power. You guys are really not into home labbing or as good with tech as you think you are lol. Lots of people run older real servers and desktops as home servers. They use way more power than laptops. Raspberry Pis sound good but use progressively more power in each generation, and still struggle to compete with mini PCs and even older laptops in performance. They also never had good performance per watt. In performance per watt basically nothing beats a Mac Mini, though other mini PCs are also good. Laptops aren't bad in energy efficiency either. They are literally designed to run on battery so have as little idle draw as possible. They would be comparable to a mini PC if you turn off the display.
Edit: Modern RPis apparently use 25W, which is firmly in the territory of what a laptop would use when not running the screen or charging the battery.
Jesus 25W is about what a miniPC would consume at a constant 30-50% load!

eBay, work, friends/family, friendly ask of your work's IT person, or just call up the local recycling/ecycling company and ask
