  • I’m living in a 15 floor apartment building with a single stairwell. (Germany, the building is from 2015)

    There’s two elevators, one of them is equipped for firefighters (manual control possible after inserting the firefighters’ key, windows)

    The single escape stairwell is isolated from the rest of the house by double doors (kind of an airlock against smoke). The escape stairwell is isolated against smoke and fire.

    Also on every floor there’s a kind of glass cage in front of the elevators with a normally open door, in case of fire this will isolate the elevators against smoke.

    In case of a fire alarm all the doors will automatically close (you can still open them. manually), additionally huge fans will be pulling clean air through the stairwell and the elevators.

    We have individual fire alarms in every room - and a common system, connected to the fire department, in the shared areas.

    So it’s a “put all of your eggs into one basket, but have a damn good basket” concept.

    Btw, I’m on 8th floor, so too high to jump and probably already out of reach of the FD’s “extensible ladder” car.




  • I recently visited a friend and noticed her laptop was turning into a spicy pillow. I opened it up, showed her which replacement battery to order and call me when it’s here to install it.

    Next week she called me, she had successfully installed the replacement battery herself. “Ah I saw where it went, I just tried”

    Typically it’s not hard, you just need to know where to look and not be afraid “ooh it’s tech”.

    There were A LOT of songs about nuclear war in 80s music. German youth in the 80s was very aware that in nuclear war Germany (being a huge part of the east west border) would just be ground zero to be vaporized in WW3.

    Thinking about Germany people associate the Autobahn, what some don’t know - there were pre-built detonation chambers so key sections and bridges could be mined with atomic demolition munitions in order to stop the east bloc tank armies from advancing.

    ChatGpt translation of the song lyrics:

    When in the Canale Grande submarines drop anchor
    And on St. Peter’s Square in Rome missile launch pads stand
    When a carpet of bombs floats over the bazaar of Ankara
    And from the hills of Olympus a Pershing II rises

    Then everything is long too late
    Then, when nothing works anymore
    Visit Europe
    As long as it still stands

    In front of the old Cologne Cathedral a mushroom cloud rises into the air
    And the sky is filled with the scent of neutron waffles
    When in Paris the Eiffel Tower bows westward in a final salute
    And near Big Ben a gentle Alpine glow appears

    Then everything is long too late
    Then, when nothing works anymore
    Visit Europe
    As long as it still stands

    When haute cuisine turns into a witch’s cauldron
    Where the cook from overseas flambés his old world
    There’s laughter and applause, even the waiter gets a kick
    What’s left to us but culture — we wish you bon appétit

    Then everything is long too late
    Then, when nothing works anymore
    Visit Europe
    As long as it still stands
    Yes, then everything is long too late
    Then, when nothing works anymore
    Visit Europe
    As long as it still stands
    As long as it still stands, as long as it still stands
    As long as it still stands, as long as it still stands



  • I can stand carbonated water and hate plain water. When I was a kid, my family wouldn’t drink water but other beverages.

    My kids (17 and 20 now) grew up with drinking water at home. Water was the thing to drink if you are thirsty, everything else was allowed but “something special” like a sweet. Going to a restaurant also was special, they could choose what they like.

    While I still struggle with water - I manage, but I still drink sugar free soda as well, my adult kids can’t understand how I like that sweet stuff all the time.

    So I firmly believe your preference is what you grew up with. You can change it, but it takes effort.


  • Look on github for Rappetor’s SV08 mainline repository. You’ll need a new mmc or sd card (both are ok) and a “five bucks” STLink programmer, but then it is quite easy to put mainline klipper on your sv08. The mainboard is a cb1 clone with the “main” ST microcontroller for driving the steppers on the same board (for cost reduction, probably)

    That’s the prerequisite for using a probe. like a btt eddy on a SV08, for example.

    Other than the SV08 has a few issues like super noisy board fan which can be very easily be taken care of. (Funnily software control of the fan is possible, but just not done in the default firmware)

    My mods are mainline klipper, btt eddy, new (printed) extruder shroud with better airflow, a microswiss hotend and a second camera (USB webcam for second viewing angle and better resolution).

    Out of the box the SV08 has a bit of problems keeping a consistent Z offset due to missing temperature calibration for the probe. More reliable solutions (ported from voron) like klicky are available. I chose eddy - but haven’t perfectly tuned it in, either. I’ll try the eddy-ng firmware (github) next week.
