Citation needed.

Edit: it’s absolutely not true universally and it’s ridiculous to suggest it is. Comparing averages will be very tricky as well.

> cheap buck from 40~80V to e.g. 5V.

That’s not a cheap buck lol. Order of magnitude more expensive then 12v not even mentioning capacitors that can withstand 80v is $$$ and your derating goes to shit

I thought x64 was better for perf per watt just because perf is so much better

I’d go a step further and say get a mini pc unless you need gpio

I keep making the same mistake. How do you make intermediary planes?

Isn’t that less efficient in power and can have different color?

It’s because building 500 units would be a non starter for many of them

>If the goal is consistency, then wall-clock isn't the simple way to do it.

It’s simpler than doing a limit on number of states, and for some applications consistency isn’t super important.

Doing a time limit also enforces bot moving in a reasonable time. It puts a nice limit to set up a compromise between speed and difficulty.

Doing state limit with a time limit might be better way to do it, but is harder.

You can get an n100 system for $110 on sale. Price went up but I still see $135 on eBay now. However YMMV because Europe prices are different

For power I don’t know about orange pi 5 but for many SBC power was a mixed bag. I had pretty bad luck with random SBC taking way more power for random reasons and not putting devices in idle mode. Even raspberry pi was pretty bad when it launched.

It’s frustrating because it’s hard to fix. With x64 you can often go into bios and enable power modes, but that’s not the case with arm. For example pcie4 can easily draw 2w+ when active. (The interface!)

See for example here:

https://github.com/Joshua-Riek/ubuntu-rockchip/issues/606

My n100 takes 6W and 8w (8 and 16gb). If pi5 takes 3w that’s not large enough to matter especially when it’s so inconsistent.

Now one place where I used to like rpi zero was gpio access. However I’m transitioning to rp2350 as it’s just better suited for that kind of work, easier to find and cheaper.

Yeah but you can get a n100 on sale for about the same price, and it comes with a case, nvme storage (way better then sd card), power supply, proper cooling solution, and less maintanance…

Something like less then 2% of people keep weight off for more then a year from dieting alone

>I experience that and just sit with it. That is the difference.

Other people might have it worse and it might stay with them longer.

Could you keep it up if you were 10x as hungry as you are now for next 5 years?

1/3-1/2 of the cost of the electricity we pay is distribution.

Some of it is physical infrastructure (transformers, wire, poles), but a lot of it is labor.

Labor is expensive in US. It’s a lot of labor to do, plus they’ll likely need regulatory approval, buying out land, working through easements.

At the same time you have people screaming about how expensive energy is.

Furthermore they have higher priorities, replacing ancient aging infrastructure that’s crumbling and being put on higher load every day.

There’s a plethora of old phones and tablets you can purchase on the cheap ($50-$100) and install Linux. They are all faster then rpi0
