@mrmasterkeyboard np.

  • I thought the glare was excessive due to the lights, but then again I'm not gonna complain more about it. Noone expects you to have a fancy mattebox with turntable to make some professional product photo.

Also even if people don't have a donor to transplant a screen assembly from or don't feel comfortable fiddling with eDP cables they could just remove the screen and have a compact AiO Desktop.

  • If it has like a "full function" #USBc port with #PowerDelivery than this can result in a sleek desktop that also looks good and doesn't require much space. Ideal if the battery is busted and a replacement isn't worth it! I've seen those in like #RepairShops where they basically setup some #MacbookPro that way as a DFU machine to reflash / reinstall other #Macs.

I think it's a necessity that we as #TechLiterates propagate the need to #UseLonger and the #RightToRepair as essential, given that #tech inherently is expensive in terms of #resources and that avoiding #eWaste and #Upcycling is an act of #EnvoirmentalProtection.

  • Tho make shure to safely remove any "#DangerPillow|s" and handing it over to the relevant #recycling provider(s)...

If I had the necessary €€€€€ I'd literally start my own "#upcycling" #business, even employ some folks collecting all the #surplus'd #Windows10 machines and just cleaning, wiping, repasting, fixing and selling them as cheap #used #PC|s for those that kinda need something to do their casual "#office", #LightGaming and #MediaConsumption.

  • I mean people are surprised how zippy even old hardware can be with just few tweaks (more RAM, a fresh SSD, cleaning it of dust bunnies and repasting the cooler with some quality (longlife #ThermalPaste, like #ArcticMX4) "#ThermalGrease" (that costs like €1/g in a 20g syringe and a #RepairShop can easily go through one in a shift)...

@wyatt yes, @EUCommission mandates it for #Laptops soon as well.

  • Granted enforcement is shotty at best and many manufacturers don't even bother to get a proper IC to trigger the correct #USB #PowerDelivery output [voltages and amperages] but just put DC voltage straight onto a #USBc connector, which is a dick move and will kill devices down the line.

@danderson personally, I prefer to go with either 48V, 20V, 12V or 5V in DC application depending on what's convenient.

The 7,9x5,5mm ThinkPad barrel jack can do up to 11,5A originally, giving you 230W at the plug end.

  • Pretty shure they did standardize it for 16A given all classic thinkPads used it except the very old ones.

That being said #USB-C-#PowerDelivery rocks and there are off-the-shelf ICs and boards to negotiate a ceetain voltage/amperage for any needs.

  • Second best is #PoE++ 802.3bt Type 4 which is ~ 60V and gets you 100W and at least 87W at the device end.

@jherazob TBH, I think we all should standardize to #USBc with #PowerDelivery & #DisplayPort!

OFC it would've been cheaper and easier to stick with HD-SDI over Fiber, 7,9*5,5mm barrel jack @ 20V DC, PoE++ (802.3bt Type 4) and USB-C but sadly #Marketing wins over #TechSuperiority.

Ich bräuchte einen Tipp zu #powerdelivery .
Derzeit habe ich einen Monitor, bei dem #powerdelivery aktiviert ist, um einen Laptop zu versorgen.
Nun möchte ich auch zwischendurch einen normalen PC über diesen #usbc verbinden.
Muss ich dann #pd wieder deaktivieren?
Wenn ich es richtig verstanden habe, dann nicht.
Aber ich bin mir nicht sicher.

I just powered my #amstrad ppc640 with a #usbc charger instead of its bulky and heavy linear power supply! I used an usb-c to barrel jack active cable. It negotiates 12v with the #usb #powerdelivery charger: very cool!

Real #GalaxyBrainChair people will tell you to "Just use #USBc!" but then you gotta show them #cursed #USB devices that ain't following USB - #PowerDelivery spec of just do the shitty #resistor that makes them just fucking #charge, so you get stuff like the #NintendoSwitch that acts as a #BatteryBank if you let it do so, as if anyone at #Nintendo ever wanted that or could reasonably assume this is an intentional #feature...

My suspicion is that the loss of power when plugging or unplugging any of the USB ports may be caused by the fact that the #PowerDelivery protocol has to renegotiate how much power to deliver (and/or request/receive) each time you plug or unplug something. This may or may not be a solvable issue, but I am not an EE.

At least the bigger battery means I don't have to think as much about monitoring remaining capacity when on the move from station to #train to #airport to plane, etc. …

@chrismarquardt Interessant...

Theoretisch müsste mensch quasi nen USB-Hub baun der PoE-Eingang upstream nimmt und zwei seperate USB-#PD-Treiber hat um jeweils individuell pro Port dies zu steuern.

  • Ich rechne mal dass dies explizit notwendig ist um Daten & Strom zu verteilen und dass "einfach nen 2-Port - Netzteil" nehmen keine Option ist.

Weil sonst kenne ich ein paar Powerbanks, die "Passthrough" erlauben und dadurch mehrere Geräte versorgen können während diese selbst Strom bekommen, allerdings schätze ich dass explizit #USB 3.0 & #DisplayPort #AlternateMode oder gar #Thunderbolt 3 & #USB4 unterstützt werden sollen, oder?

It's mad to me that a USB C battery pack could fail to charge a laptop because the cable was the wrong way up...

One way up - laptop charges battery pack (wrong)
Other way up - battery pack charges laptop (correct)
