it was a cheap kit, i made ten, for a decent sample size, and for practice. thanks for your kind attitude.

am well aware that leaded solder still has some niche applications, but the comment i replied to called lead-free a "clusterfuck" without any regard for the huge public health benefits.

i hope you agree it's good that e-waste isn't toxic.

You've mis-interpreted why I commented.

aerospace is a small part of what soldering is used for, globally. the majority is consumer electronics.

keeping lead out of people's homes is a valuable public-health move, not a needless "clusterfuck", as the comment I replied to said.

I built a few identical fidget-spinner toy kits using either leaded and lead-free solder to decide which type I should keep buying from then on, the leaded stuff was admittedly a tiny bit easier to work with and usually left a slightly shinier (better looking) surface, but not to an adequate degree to justify any real risk (or even continual worry) of brain damage et cetera from voluntarily raising the lead level of my home. Your comment seems unbalanced, to me.

plus the fact that exFAT read/write is cripplingly slow, a MacOS bug for years and years now.

The electronics to drive the right frequency for efficiently heating ferrous metals (about 25KHz) are affordable. The electronics to drive the much higher (at least double?) frequencies for non-ferrous metals safely are not so affordable. It would add more to the cost than a new set of cookware. Cast iron is the king of cookware and works great on IH, anyway!

You can put a few mm thick piece of steel on top of the hob and then set your copper pan on that, as a workaround.

A myth. Copper and aluminium won't heat on a consumer-grade kitchen induction stove, which only have a set of coils designed for ferrous metals, but restaurant kitchen professional IH stoves can use the different frequencies that heat non-ferrous metals, and a forge or melting furnace can indeed melt any metal, ferrous or not.

presumably means "error correcting code", to save the next person from looking up jargon.

Good project, but I've always hated the word "blogroll". It's a pun on "bog roll", like toilet paper, isn't it?

What is fenced off for Europeans? Admittedly I've been living outside of Europe for some time, but some of my self hosted stuff is still based there, and a lot of friends, and I haven't had or heard of a problem with being "kept out" of new products.

My Kirb. What is this negging "yeah if you're into basic stuff" tone? I'm a fan of the genre, I own quite a few SBCs with various chipset manufacturers, and I use them for all kinds of things, from AI-vision voice-trained mobile robots to "simple" Kodi/emu boxes, and I can guarantee that so long as you notice the specific sizes and pinouts - CSI is CSI, DSI is DSI, Vulkan is Vulkan, et cetera.

Some of the more complex Adafruit / Pimoroni / Seeed hats are very specifically written for Raspberry GPIO, sure, but they have the problem of keeping you on an old OS after a year or two, unless you're willing to put in the same amount of effort as porting their examples to a different GPIO layout.

There are tons of alternative single-board-computers available. The Orange Pi 5 is great for MUCH higher end performance but still under (usd)$100, and there are other options (Orange Pi 3? Banana Pi? Radxa RockPi?) that still match or beat the Raspberry Pi 4 performance for the same recommended retail price, but new stock is available for the sticker price.

Raspberry Pi OS is pretty much Debian with Broadcom drivers they haven't up-streamed yet. It runs on other SBCs, or there's Armbian, Arch for ARM, RebornOS, et cetera et cetera, all packaged for ARM uboot SBCs.

By VPU, I meant the square on the board that eats h.265 hw_enc and hw_dec and things like that, yes. I've been told it's a separate square from the GPU, by someone who is full-time waist-deep on getting Arch running on that hardware, so I take it as fact.

Oh no. The prospect of gstreamer being the only way... Oh no.

Maybe there's a zsh plugin or smth that autocompletes sane defaults? AAAAAAAAHHHHHH there surely isn't, anyone merciful enough to make one would just use ffmpeg instead...

Yeah it's the first under $100 system I've tried, (and I'm a fan of the genre) that's truly a desktop replacement in terms of being a snappy responsive desktop even with lots of browser tabs, etc.

I do know they have their own special sauce to talk to the NPU. I was discouraged from making the effort myself because their special sauce to talk to the VPU has barely any ffmpeg support, it p much only uses gstreamer, and I'm neither a masochist nor French so that's a non-starter.

The RK3588 seems like a beast for performance per dollar, I have one running desktop Linux for emulators and games, but I haven't used the NPU yet, because I haven't taken the time to figure out how to get OpenCV to talk to it.

Is Rockchip's stuff "good", as NPUs go? I'm thinking of buying another 3588 SoC for my robotics hobby - you seem like you'd know if that's a decent idea or not.
