How do you even use a jar with a rubber band? Do you wrap it around the lid and use the increased traction to pull it open, or is there some kind of black magic at work?
Meanwhile, while I'm supposed to write a report about this Montenegro citizenship program https://tranio.com/montenegro/passport/, I discovered that you're supposed to pour juice/milk/whatever comes in a carton with the opening on top, and not on the bottom, because there aren't waves and bubbles to disrupt the stream like that. And of course, when it's half empty (half full for optimists), then you put the opening at the bottom when pouring it. |

Rubber band around the lid usually works. For extra difficult jars a separate band around the body of the jar for extra grip works well. The band on the lid is best to be the right size to be tight and only going round once - not doubled over.
Better think of a synth related tip now! |

Okay, so the trick does work thanks to the increased traction offered by rubber, thanks for the explanation! |

A dry teatowel over the lid also works, or your untucked shirt. |

trust me
the BEST way to open a glas is a spoon or the back of a fork
put it like that

press it softly until you hear the Glass breathing in
then open it without any force |

lifitng the lid is only useful if it is hard to open because of a vacuum, then it does work though. I usually use the rubber-band-around-the-lid
but sometimes it does indeed work better to use a towel because it gives you more to hold on to. You can also use a hammer to smash the glass.
besides opening jars rubber bands can be used to make music.
And if you have some spoons and are feeling adventurous you could build this:

some tips on using a desoldering gun, although it's pretty straight forward it took me some trial and error to get a technique that works for me (YMMV).
I am using the ZD-8915 which is identical to the SS-331H you can get from china (I got mine from https://www.eleshop.nl/ which was actually cheaper
and of course faster delivered). So far I've only used the smallest nozzle (it comes with 3 sizes) but it will probably work the same for all of them.
I set it at a temperature of 375C (for leaded solder on a double sided PCB).
don't put any pressure on it just let gravity do the work, you also don't have to move it around on the solderpad.
give it enough time to melt the solder, about 3 seconds works for me, before sucking it up.
it can get clogged rather fast but comes with some small rods to clean it. I clean it after about every 5 desoldered pins. (It might be different with a
larger nozzle though it's not the nozzle itself that gets clogged)*
I clean the solder collection tube and the filter after about 100 desoldered pins. I recommend to order some extra filters for the gun right away.
There is also a filter on the base but that one doesn't really get dirty.
As with other desoldering methods you might have to apply come fresh solder if you can't get it cleaned out in one go.
* edit: just read some reviews and apparently a higher temperature (450C) will prevent it from clogging. _________________ "My perf, it's full of holes!"

Oh yes, smoke. It was actually a module already in my synth, a simple fixed voltage source providing +1V, +2V, +5V, and -1,-2, -5. Hence the use of the LT1013. Not sure what happened, it worked fine for years, suspect I shorted the output (though the opamp is meant to withstand a short indefinitely).
Bit disconcerting to smell burning from the cabinet, open it up, and see smoke!) Fortunately no other modules were damaged. The power supply was pretty hot though. |
