Hardware design is actually all about finding capacitors that match your PCB in color.

@janamarie @gkrnours The colored sleeve is just printed heat shrink tubing. You can get custom printed heat shrink tubing for fairly cheap, which you can then either apply on top of the manufacturer's or you could first remove the manufacturer's heat shrink.

anyone have experiences with encryptfs?
would love to test it out, reinstall with FDE isn't an option :crywhy:

@k I used it like 15 years ago when it was standard in Ubuntu. IIRC it worked fine. Being FUSE it's not going to be great for I/O performance like compiling software in it, and it's security guarantees are a lot weaker than those of a LUKS volume since IIRC it leaks folder structure and file sizes.

@k you're welcome, good luck!

With the introduction of Dolby Surround 7.1 in 2010, Sony were eager to put out a full home theater system. One of their early models, the HT-A7.100, included a revolutionary evolution to the standard stereo jack: the 7.1 surround jack, allowing all 8 channels to be sent over one cable.

@mia The 8 ring one could even support VGA

On Friday, I had pan-fried, left over, macaroni cheese for dinner. The START / STOP buttons on my microowave have stopped working, so I couldn't reheat it.

I'm trying to fix the buttons now. They are on a flat plastic panel and seem to have contacts that get better contact when pressed, and I think that they now longer "spring" open again.

Does anyone know how I could fix these?

@volcan01010 Keypads like this are terrible, you're likely to break it even trying to separate the layers. If it's the front foil that has become distorted maybe glueing on an extra piece of a similar material could help it spring back? The only proper fix I can imagine is replacing the whole thing with either a part from another device of the same model or a custom PCB. A custom PCB to replace that thing would probably end up costing around 20$.

I just tried a few AI plugins for and they were all bad. This domain might be a great test for . I predict these failings are unlikely to be fixed any time soon:

  • Layout was poor
  • They can't create components
  • Laughably complex object hierarchies (everything was enclosed in a frame)

Of course things will improve, but I expect fixing these deep structural problems are a function of many new constraints, likely beyond what today's LLMs are actually capable of. @simon ?

@scottjenson This problem reminds me of AI-generated printed circuit board layouts. A bunch of companies have been trying to get that one right for years now, but the 2D nature and the topological constraints of the interconnections make it really hard to do with AI.
