From the service manual for the Yamaha DX-100 FM synthesiser. The way this looks to me, both the 12v DC power supply, and 9v DC battery power get routed through exactly the same voltage regulator.

So it should be possible to just straight replace the 6x C-cells with 3x 18650s without needing to make any other changes, right?

I know exactly enough electronics to be dangerous, which is why I'm double checking here in case I've failed to account for something.

I'm aware that fresh 18650s put out a little over 4v, but I seriously doubt the vReg tops out at exactly 12v. I can disassemble the unit and check part numbers etc if necessary but I was really hoping to avoid that as it's quite a chore.

So a few months back I found an EasyThreeD K7 in the ewaste bin at my work. Probably where it belongs tbh but I figured hey.. free printer. It works okay, sometimes. Usually okay for small and simple stuff, but tends to fail on anything serious. In the process, I've found my way around openSCAD, Cura, learned what can go wrong, how to troubleshoot, etc. It's been fun and educational. So, not a total loss, especially for $0 upfront. I'd feel cheated if I'd actually paid for it tho.

OTOH, I've wasted enough time, energy and filament on failed prints that its time to upgrade. I'd like to avoid Prusa and Bambu for personal reasons that I don't really want to go into on this comm. This is only ever really going to be a hobby for me, I see it being useful for fixing little stuff around the house like broken buttons and catches, building small ornaments or containers for things, and the occasional functional project like stands and mounts for devices or the odd project enclosure.

I've also used the Ultimaker 2+ at my local library. Although, Ultimaker seem to be focused on industrial applications these days; probably overkill for my purposes.

Prefer magnetic / flexible build plate, but glass isn't a deal breaker so long as its heated. I'm fine with manual leveling and offset so long as it's marginally more automated than the K7. I'm also alright with tinkering, replacing parts and firmware upgrades. I'd prefer a good community and aftermarket rather than having to rely on manufacturer support.

Based on my research, I'm leaning towards an Ender 3, although I'm not entirely sure what the difference is between models because the naming scheme is confusing. It seems to be a more open platform, and the community support and aftermarket seem great. But before I go ahead, are there any other brands/models I may not have heard of that I should be considering?

SOLVED: gPodder does this. I really should have known this.

I'm trying to be a little more deliberate about my media consumption, and less reliant on my phone, so I recently picked up a dedicated audio player. I have the music side sorted, but the other thing I listen to a lot is podcasts. So, what I'm looking for is a desktop podcast client that can download new episodes and track listens, but also transfer podcasts to the player. Somewhat like how desktop music players let you manage a device from within the app. From what I've seen, there's a lot of nice clients out there that do the first two, but I can't find anything that does the third one. Or alternatively, I don't have any particular loyalty to desktop music players, so one of those with device management that can also do podcasts would work too.

The player shows up as USB mass storage, so I'm not opposed to doing the syncing via a file manager or script, I'd just prefer not to have to.
