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?!

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.

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.

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.

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.

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

IIRC, this is actually done at some point in the books.

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).

Reminds me of this: Falsehoods Programmers Believe About Names

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.

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.

Sorry dass ich nichts hilfreicherws beizutragen habe, aber der Janosch passt hier einfach zu gut:

Herr Janosch, schwere Entscheidungen, wie trifft man die? "Man schreibt die Alternativen tabellarisch auf einen Zettel. Anschließend legt man den Zettel nieder und wirft einen Löffel auf den Zettel. Dann geht man weg und lässt den Löffel das regeln. Sein Problem."

It is more efficient to have a ship moving with cargo than without, but that doesn't mean there aren't additional emissions. The ratio of profit to effort is just higher because there is some profit as opposed to none. You wouldn't load a ship up with useless mass you can't sell just so you're shipping something.

Your argument is like always running the heater in your car because that way the engine heat is at least used for something. Yes, technically the efficiency goes up because more of the energy in the fuel is harnessed. But that doesn't mean the fuel usage or emissions are any lower, and in the summer the heater doesn't do you any good either.

That's why I don't let every device decide individually. I know my router (FritzBox) prioritizes the pi-hole (it's even called "preferred" and "alternative" DNS-Server in the UI)

I have my pi-hole setup as the upstream DNS in my router, with cloudflare as a secondary DNS. That way, all my devices always use the router for DNS (since that's what is advertised in my DHCP) and the router then uses pi-hole if it's available, or cloudflare if it isn't. But the individual device doesn't get to choose between different servers.

For the dynamo, a drawing can be found on the manufacturer's website: here

I can't find anything on the rear hub right now, you will just need to measure it yourself. As long as the spoke hole count matches, compatibility shouldn't be an issue.

That study states that brain damage can cause more conservative views, but the reverse isn't true. Not everyone with conservative views has brain damage.

Tightening the belts seems to have helped, but I will have to do some more printing to be sure. Thanks for your help!

The belts are parallel to the axis, but I will try tightening them some more.

This is a 40x40 cube printed in vase mode:

The corners look pretty okay on that:

But I don't see these kind of results on real-world parts. I guess I have to print some more test parts to narrow down the problem.

That might be part of it, my filament is probably pretty wet. I'll try some other rolls of filament.

The part is just pretty small, I have the EW set to 0.45 mm withe 0.4 nozzle. But I will try turning it down further.

The rounding looks much more extreme than what I would expect or have seen on other printers I worked with (mostly Ultimakers).

It's a printer of my own design running marlin. I'm going to try disabling input shaping, but if I remember correctly the problem was already there before I ever enabled it.

Good point, see my edit

I'm guessing it's about documenting the assembly of safety-critical components. If some part of, let's say an airplane fails because a bolt comes loose, the manufacturer wants to have a paper trail attached to it to prove that this specific bolt was indeed torqued to the correct spec. Connecting the wrench to the network could make this documentation much easier.

You can try to disable software End-Stops with this gcode:

M211 S0

Be aware though, if you do that, there is nothing preventing your printer from trying to move beyond the hardware limits and possibly destroying itself. You can enable the end-stops again with:

M211 S1

I remove the chain and let it soak in WD-40 for a while. Then I spray it down with degreaser and rinse with a power washer. As long as the chain is well lubricated, I don't have any issues with corrosion.

Also, some quick-links are reusable. You should check with the manufacturer. KMC has a type that can be reused 5 times. With a bit of practice and a good chain breaker it is also pretty easy to remove and reconnect a chain with no quick-link at all.

It's called HDR (High Dynamic Range) photography. Your phone is taking three pictures: one at a medium exposure, one at a bit higher exposure and one at a bit lower exposure.

The higher exposed picture will have a blown-out sky, but more detail in the darker area, while the lower-exposed one will have a correctly exposed sky with the darker areas underexposed.

These pictures are then combined by taking the correctly exposed areas of each picture, i.e. the sky from the low-exposure picture and the shadows from the high-exposure one, giving you a single picture without over- or underexposed areas.

I don't know about OpenCamera, but you should be able to select the size of the exposure bracket, meaning how much higher or lower the different pictures are exposed.

Solvespace might be exactly what you're looking for. It is FOSS and works well for simple models. Some functionality is missing though, for example chamfers and fillets.

Alles trägt zum Klimawandel bei, die Frage ist nur wie viel. Ich fände eine einheitliche Kennzeichnung, wie groß die Auswirkung ist, sinnvoller - so ähnlich wie der Nutri-Score.

Das hätte eine tatsächliche Informations-Funktion statt dieser generellen Schuldzuweisung ("Alle Fleischesser sind böse"), die wahrscheinlich nur begrenzt effektiv wäre.

Those adapters should definitely be fine for 24 V. Running the fans off 19 V will probably work, but they will run at slightly slower RPM (probably not a big problem for a filter).
