  • Three teabag types were purchased online (Amazon and AliExpress) or in a local supermarket. The online-purchased teabags were ordered empty (with no tea inside) and with a known polymer composition

    The third teabag type (sample 3), bought in the supermarket, was a regular tea brand of green tea

    300 teabags were transferred into a 1 L beaker (pre-washed and sterilized) containing 600 mL of Milli-Q water at 95 ◦C with constant stirring (750 rpm).

    It sounds like they were using a magnetic stir bar rather than a spoon or rod but still, 300 teabags, most of which coming empty from Amazon or AliExpress in 600ml is ridiculous.

    I’ve a massive blob like this one time when the nozzle got clogged and the extruder created enough pressure to push the filament through the threads of the hotend block. It was on an Anet A8 and I ripped a lead off the thermistor trying to get the plastic off so I ended up replacing the entire hotend.

    You can try to heat up the hotend to a fair bit under the melting point of the filament to where it’s soft and somewhat pliable but not runny or sticky and then trying to peel it off. Though you’d risk damaging any leads to the thermistor, heater, or your hands if you’re not careful.

    Good luck on fixing the printer and getting back to printing again. 3D printing is a really time consuming hobby




  • What does being a person mean to you? Could a sufficiently advanced AI become a person and if so, at what point would it become a person that deserves to be treated the same a human? If a machine can be a person, would it be plausible for a person to become a machine? For example, with transhumanism being possible, would a human that has ship of theseus’d with machine components instead of biological components become a machine instead of a person?




  • I was born in the current millenia so I wasn’t around during the aerospace boom but it makes me kinda sad that looking back, there was so much innovation and hope for a future. I remember talking with some older people in how they thought we’d be living on the moon or Mars by now after seeing the Apollo missions and seeing commercial supersonic flight. I still remember going to the library and checking out books about how technology was developed and reading in awe about the insane engineering behind each thing.

    It’s just sad that all of the potential and movement was just shutdown by politicians and the rich just so they could get that extra little bit more wealth and power year after year.
