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.

Right, I might just see what cooler I can get second-hand. Thanks for your input!
My 5 year old notebook is starting to show it's age, so I want to finally build a "real" PC. I rarely play games, so this is probably overkill - But I don't want my PC to be what's stopping me. I also expect it to last a while. I chose all AMD because I'm running linux, and AMD seems to still be the best choice for that. I found a couple similar posts on which I based this list, so most of the parts are probably fine. I'm unsure about the cooler: How much headroom should I leave? This one is rated just 10W higher than the CPU TDP, so it might be cutting it too close.

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.

It looks to me like a JST SH connector: https://www.sparkfun.com/products/retired/10357
Measure the distance between the two pins - if it is 1 mm, this is most likely the connector you're looking for.

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.

You can bring the resting position of the brake lever closer to the handlebar by turning this screw clockwise. The brake lever looks a bit short for my taste, it's probably not designed for use with that type of shifter. But with a bit of adjustment it should still be usable.

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

If that freehub is constructed like the ones I've taken apart before, you're out of luck. Like you suspected, the teeth lock the rotation of the freehub to the hub, unless the screw in the back is taken out first.
You can try hammering in a (slightly larger) torx key or using an easy-out (probably won't work if it's very tight).
As a last resort, you could try to drill out the screw (only so far that the freehub comes off, you don't want to drill into the hub). Then you should hopefully be left with enough left of screw to grab with a pipe wrench.

Unfortunately, this might not be easy to find a solution for. The larger thread size doesn't seem to be a standard bike pedal thread, so finding a specific adapter is probably not possible.
Another solution might be to use some kind of threaded inserts in the cranks (this would probably require drilling the cranks out for a larger thread). But the standard pedal thread of 9/16-20 is not widely used anywhere else, so finding the inserts (let alone a left-handed ones is probably next to impossible.

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.

You can host a Firefox sync server yourself. You could run that on something like a Raspberry Pi in your local network. If you need remote access, use something like cloudflare tunnels (although I guess that's something else to be paranoid about).

Interesting! Turns out I've been doing parallel view all along. I was wondering why some of the images posted here look a bit weird to me - looking back, the ones that work for me are actually for parallel viewing.
I just found out that the Getty museum released a lot of artwork into the open domain, including quite a few [stereographs](https://www.getty.edu/art/collection/search?object_type=Stereograph). These are meant to be viewed with a [stereoscope](https://en.wikipedia.org/wiki/Stereoscope), but I’ve found they work amazingly well in crossview.

What did you expect? We're talking about one guy who might have lived over 2000 years ago. You're not going to find his birth certificate and social security number.
The best anyone can do is assign a probability to his existence. And reading the article you yourself linked to, that probability seems to be pretty high.

I built my 3D printer a couple of months ago, but I can't get it to print sharp corners. The corners in the picture should be 90°, without any fillets: ![](https://discuss.tchncs.de/pictrs/image/acf626c9-9cbb-4b8e-8294-c509ceaff3a7.png) During this test print, I played with multiple parameters: speed, temperature, acceleration, junction deviation, linear advance. All of these were also individually tuned previously. Nothing seems to make a difference. Could this be a issue with the construction of my printer? I'm beginning to think my hotend isn't rigid enough, but then I would at least expect better results at low speeds. Edit: the printer is a CoreXY of my own design running Marlin 2.1.2.1. The Slicer is PrusaSlicer with most settings left as default (but increased speeds)
