Knowing how stupid and dystopian we can be ..... I'm going to guess that someone is going to give this little thing a hypodermic needle to deliver a neurotoxin or a virus.

If we can't turn it into a spy .... we can weaponize it.

  • There are a few companies and universities playing with this kinda stuff, but the ones that are as tiny as that usually have no ability to transmit any data or even record anything from what i have seen. They just fly and thats it.

    Why ESP8266? I understand not going for the ESP32-C6 because of the current desaster of support, but why not any other more modern MCU instead of one that is essentially EOL?

    Yeah, I considered a similar image, but also:

    pressure gradient expected for air pushing fans
    (But I also realise that one would have to be careful when designing this, to prevent turbulence in the center, causing heat generation.)

    pressure gradient including cabinet airflow

    Which I considered would be a big factor.


    Short fins should be cheaper, yes, if they use the skiving process. ∵ shorter fins ⇒ less total force required ⇒ cheaper machinery usable/ longer machine life due to lower stresses.


    making its average temperature higher before ejection, lowering heat transfer

    Well yeah, but I feel like the air coming out of the fins was not hot enough to say that.
    I would rather put the factor of higher air density (caused by a higher pressure) between the fins enabling higher heat transfer.
    Of course, which factor affect more in that case (pun intended), would be the engineering part.

    Pretty sure the thermal engineers at ASROCK are much smarter than you take them for

    Yeah, probably just my bias after having that bad experience with ASUS Gaming laptop, in which they stuffed components way above the case's TDP.

    GDDR6/6x runs hotter than GDDR5. You need to learn a lot more about PC components m8

    Like I said, you cant compare the 2 cards at all other than they look similar. Pretty sure the thermal engineers at ASROCK are much smarter than you take them for
