You can use a boost converter to boost the 5V of an USB port to the 19V your notebook needs.

Assuming 5A output from a powerbank (which is probably about the max you will get without USB PD), you could theoretically get 0.55A at 19V. With the unavoidable inefficiencies, you will get less.

So, maybe enough to very slowly charge your notebook while it's off. But when it's turned on, the battery charge will still drop.

Sure, the skull is biodegradable. But didn't you know that large-scale human farming is responsible for the vast majority of CO2 emissions?!

Thanks for breaking it down for me! I think I'll stick with the B650 motherboard for now.

Right, I guess I assumed CPU naming makes sense, so surely the lower number CPU must be worse in every way, right?😜

Looks like going with the 7700X is a no-brainer for me then.

As for your upgrade recommendations: Can you explain the benefits of a higher-end mainboard? I would think the mainboard shouldn't make a huge difference, as long as it's from a reputable manufacturer and compatible with all the other parts.

Thanks for your help!

Right, I might just see what cooler I can get second-hand. Thanks for your input!

This seems to be a bug in the slicer. I'm seeing the same issue in OrcaSlicer if the skirt height is set to more than one layer (even if the skirt is disabled). This makes sense if a skirt is used (can't print a continuous spiral if you have to switch between printing the object and the skirt), but not if it's disabled.

What slicer are you using? If it's a PrusaSlicer fork, this is likely the same bug.

From a cursory read of the datasheet, using the "dead time control" pin seems to be the way to go. Basically, this pin is used to set the voltage, while the error amplifier inputs (that's the closest function to "over current protection" this chip has) are used to adjust the output according to the load. For your application, you probably don't need to use them at all.

My instinct would be to disable the error amplifiers by connecting pins 1,2,15 and 16 to GND. You can then connect the wiper pin of the potentiometer to the deadtime control input, with the other pins of the potentiometer connected to GND and 3.3 V.

I haven't worked with this chip before, so take this with a grain of salt. You should probably use a simulation tool to check the circuit before you start destroying chips.

Do you expect every meme to be meticulously handcrafted? It's a stupid joke, not a work of art.

Close, but the word ends in -le, not -ie. The -le suffix is used as a diminutive form in some German dialects.

A small pair of vernier calipers. I don't use them a lot, but sometimes they come in very handy.

Klar hinterlässt das Spuren, aber nichts was man mit etwas Seife oder Spüli nicht wieder weg kriegt. Der Dreck ist ja in dem Moment schon gelöst (sonst wäre er noch am Fahrrad). Nur Festtrocknen würde ich es nicht lassen.

Ich wäre nur vorsichtig dabei, mit höherem Druck direkt an die Lager ran zu gehen. Danach hast du sonst auch Wasser in den Lagern und musst doch alles auseinander bauen und neu fetten.

My router is called Jupiter, everything connected to it is named after a moon. Callisto, Ganymede, Thelxinoe, Kallichore are what I'm currently using.
