Help with removing freehub
  • 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.

  • Where do I get an adapter for this oddly sized pedal thread?
  • 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.

  • Fahrrad mit in die Dusche?
  • 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).

  • Beyond TinkcerCAD
  • For quick, uncomplicated parts, SolveSpace works pretty well. It's missing some features (like chamfers) that limit the kind of parts you can design, but it's lightweight and relatively easy to use.

    For everything beyond that, FreeCAD seems to be the only option (Or one of its forks, I find Ondsel easier to use). It has some issues and a pretty steep learning curve, but it is open source and you can design basically anything with it.

  • A superb scene in the beautiful Kinkakuji Gardens, Kyoto, Japan. Carleton H. Graves, 1902

    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.

  • 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.

  • Wie trefft ihr schwere Entscheidungen?
  • 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."

  • We lost four men on the last expedition...
  • 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.

  • When Pi-hole is down?
  • 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.

  • Building my own wheels and making sense of the spokes length
  • 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.

  • What is causing rounded Corners on my prints?

    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 The Slicer is PrusaSlicer with most settings left as default (but increased speeds)
