The new forums will be named Coin Return (based on the most recent vote)! You can check on the status and timeline of the transition to the new forums here.
The Guiding Principles and New Rules document is now in effect.
It's a pretty nifty use of a Zero W (I'm SSH-ing into a Gameboy, LOL), but I'm having this weird problem where the sound is horribly distorted and games lag every other boot, I can't figure it out.

Fixed the sound problems etcetera. GPIO pins weren't getting good enough contact. I accidentally broke one of the interface board's stand-off screws by over-tightening it, so only 3/4 screws are where they should be.
Still, it works fine now though, just as a bit of a bodged job. :rotate:

Note to self: Do not attempt to upgrade the kernel on a device that relies on binary-only device driver modules, compiled against a very specific version of said kernel. Doh!
I've been suspecting that's what the youtube app does on mobile, but I haven't been arsed to get out wireshark to have a look.
It genuinely amazes me that people sincerely use YouTube without some way to mitigate the adverts. I just can't endure the sheer density of ads. Thank god for ad-blockers - although I have the feeling that Google will close that loophole soon.

Youtube refused to work when I had it ad blocked on pihole.

I'm shocked that people still use YouTube without some sort of app (that, among other things, blocks ads and has a less terrible interface).
Google does block that with API changes from time to time.

I set up Firefox with uBlock Origin, and that combo seems to do the trick.
So you need a breadboard to do anything with it? I guess I'm not fully versed on what they mean by 'microcontroller'.

Looks like a Pi board without the standard I/O - you have to roll your own. Which is both good and bad; it’s going to save space and parts but be a bigger technical challenge.

Pretty much. It's more like an Arduino in terms of what it can do.
At $4 I've been think of the cool things I could do with it. Right now, I think a temperature + humidity sensor and a small e-ink display and I could easily make a device for cheap that measures and reports temperature/humidity in each room its in. Something that would be actually useful to me.
Another thing I've been thinking of for a good while is building a replacement for nuclear detector DAQ (data acquisition) system that I have to use for research at my school. The thing is built into old P3/P4 PCs with ISA cards, which, how many people have seen an ISA card nowadays, much less a motherboard that supports them. The PCs are on the edge of failure, and the replacement for them is very much not cheap.

Not sure? PCI to PCIe is easy enough but ISA was a totally different standard, not just electrically but logically. You’d need some kind of active element on the board at least.
I think so, but it would require significant engineering resources to get everything working correctly due to how PCIe and ISA cards are addressed. Our engineer looked into building new cards for the PCIe bus but even getting through the specifications alone was months and months of work. The PCs are running RHEL 4 (maybe even RHEL 3), so the software itself may not even be easy to port to a newer version of linux.

Is there something about the Pico that makes this possible now vs having used something like a Pro Micro (arduino) in the past?

Really more the cost than anything else. Looking at the arduino website, you can get almost 3 of these vs. the cheapest arduino listed there.

Are there any mods that would let me secure a pi in a midsize tower in a drive bay? So I could access the ports on the front and provide power with the molex? I have a pi3 with a pretty typical case.
I'm going to be dumping some old parts into a case (ATX mid tower) and would like to arrange things to be more tidy. I figure if my home server can have the pi I use for Pi-Hole and managing some network storage that nested in it, would be nice.
You may have to make it yourself out of a drive cover and power components from a drive bay addon.
I haven't looked whether anyone sells Molex-to-Pi power adapters. It may be out there. It's 12V no matter what so it should be fine from a concept level

Would you just go molex 12v to USB into the pi? I figured there would be some sort of voltage/current protection in there somewhere.
You do. Pi wants 5v, and the older ones don't even want the higher amperage line.
I've seen a lot of people just route a USB cable back into the case to power it, could do something off one of the rear ports and just come back in one of the PCI bays you have open?

My motherboard has a pin-out for the front facing USB ports. So it might be a good idea to get the ~5v you need that way, or use a powered hub just resting inside the case somewhere.
If you know someone with a 3D printer, your imagination is the limit, really.
Actually that would be a cool idea for a project. I could use one of my empty 5.25 bays to mount an LCD (driven by a Zero 2 W) that shows temps, htop or pihole stats over SSH.
I'm thinking a Silverstone GD-09 and just rewiring a USB expansion card I have sitting around to occupy a PCI-E slot but not actually interact with the motherboard. Use it externally for a USB input and internally wire it to power the Pi. If I can figure out a way to do the same with an NIC and network switch I'll be set.
Ultimately I want a NAS/Project server on the PC end, and a nested network switch and pi internally that I can SSH to. I have a KVM and HDMI switch so I can access video out directly. Ultimately I like the idea of putting a screen on the front with network status and Pi-Hole stats or something. I've never played with the 7" pi touch screen but it seems like it might be fun.
I don't have a ton of free time or infinite resources so this is a good project for a year or so. I'm sure I'll be dropping in with many questions.

The Pi Pico
The things cost $4. They are based on a dual core Cortex M0 chip built specifically for them.
At that price, I ordered a few so I can get into all kinds of trouble.
