USB-C PD: New Technology Done Right
hackaday.com
There is a tendency as we get older, to retreat into an instinctive suspicion of anything new or associated with young people. All of us will know older people who have fallen down this rabbit hole…

I wanted to share this opinion on Hackaday about a topic that is the usefulness of a something that has become ubiquitous relatively fast.

This techonolgyy has a lot of potential, what do you think?

      I honestly don’t know how to take this 🤔

        It’s very difficult to quote Douglas Adams without sounding like you’re pandering to nerd culture. I don’t think AI could pull it off.

        I don’t know what to think of someone who could blast off accusations like this, either.

        Edit: Oh. The accusation is even dumber. It’s just the header OP wrote. That was just direct to the point writing. AI or no, who cares about two tiny paragraphs.

        Edit: Filled in the words my brain thought were there for everybody.

        Just your normal redditor who didn’t create anything trying to feel superior by dismissing someone else’s effort. Don’t overthink it.

        Thank you. Also I could have written it better. Reading what I wrote again I wasn’t happy at all. It really sounded a bit fake…

          you wrote it? Cool!

          I’ve really been loving USB PD, and retrofit into several devices i use. My big next interest is the USB PPS, allowing devices to request extermly minute adjustments to the voltage, instead of just “9v”

            No, I only wrote the intro of this Lemmy thread. It’s the part that @rusticus@lemm.ee said was AI generated. At least that was my understanding.

            I really hope that the hackaday article cannot be confused with ai generated garbage… Or maybe my taste is really bad!

            A question because I don’t really understand:

            Does those “really minute” voltage adjustments really matter for the vast majority of things you can use USB PPS for? I’m sure there are some devices out there that do, but I would think most don’t care too much if the power is 9VDC or even 6VDC or 12VDC for brief periods. Perhaps the slightly increased lifespan might matter or not.

              Yea, i do think it will help, primarily with battery charging.

              Right now, in order to protect the battery, the phone will request 9v, then step it down as the battery charges, and send a reduced voltage to the battery, so over time the battery might see 9v… 8.95vm 8.9v, 8.85v…

              This allows the step down to happen at the charger, instead of in the phone, increasing efficiency, and reducing heat in the phone.

                I think there might be an issue with the propensity of people to use random chargers. If it fits, it has to be OK right? I’m not sure one should trust the charger to step down the voltage as it charges a device. Lots of poorly designed aftermarket chargers out there and you won’t be able to make the bad ones all disappear overnight. The device needs to protect itself from the stupidity of the user.

                  Definitely get what you are saying, but I already trust the charger to take 120-240v AC to 5-48v DC.

                  Going from 9.0 to 8.85v is a much smaller regulation
