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).

 

I just found out that the Getty museum released a lot of artwork into the open domain, including quite a few stereographs. These are meant to be viewed with a stereoscope, but I’ve found they work amazingly well in crossview.

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:

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)
