  • Building a USB-C DAC in as small a package as possible

    Jump

  • I'm in no position to discourage you from building this, but this is a fsr greater project than you're writing it to be. Send me a link to the git repo, so I can tag along and keep updated!

  • Thanks for the detailed answer, that helps a lot for my understanding.

    The project sounds like a lot of work, especially for such a niche application. Do you have a crowd to support this (with time or money) or do you plan pay for this and sell it in the end?

  • It somehow feels like you put a lot of thought into this already and missed starting from the beginning in this post.

    What device do you want to have a USB-C DAC for? What's the actual size limitations and what power do you want to draw that would need a heatsink? Do you have specs in mind, or is there a comparable project already available to look at?

  • Sure thing, if that's allowed: 8volt.at

    We're doing custom builds for research as well as exhibitions and develop new machines and parts for industry ;)

  • I did that for almost 15 years, now I'm running a company developing embedded electronics using them daily.

  • I honestly consider them to be a consumable.

    The ones I've used always get splashes of solder, flux and other uncleanable things onto them at some point. If it gets too much, I'll switch to a new one.

  • That's actually a great video, no-ideal opamp characteristics have caused me a lot of headaches on multiple occasions in the past.

  • Surprisingly enough, shady USB-C multiport adapters can be dangerous

    Jump

  • A regular USB-C hub would be an idea, but may not work with regular chargers..

  • safe?

    Jump

  • Then this is not safe.

    The maximum charge voltage for a lithium cell is 4.2V while USB will provide 5V. It may work for a while, it may fail in a safe state or something gets hot and burns.

  • I never knew that USB-C extensions are not allowed for a reason

  • Pretty much this, thanks for the summary

  • Pretty much. I'm not even sure if regular USB ports can talk to pins individually, let alone test them for shorts.

  • Interesting, I just uploaded the .mp4 directly to lemmy and assumed this to be working. How else would you share a gif/short video?

    Would anyone be interested in getting a prototype and helping to test it?
