    right, I mean, I'd probably write something like "no more than two specks of dust on the entire display" but they all do stuff like this

    should be OK. look at Fig 1: Vgs=3.3, Vds=4, Id=~80A, so much more than you need

    last time I heard of that, OSI had the opposite position; did things change?

    🦝 roommate brought me this mouse in absolutely pristine condition. not only it had clearly never been used, but the plastic hasn't even yellowed one bit

    ok so here's mine I think this means it's good?

    now if i touch the crystal gently though? entirely different story i wonder if you could use commodity crystal oscillators as piezo sensors or something like that

    nRF24L01 has a mode where it just transmits its carrier (for compliance reasons) so i wondered how much it's going to drift. the answer is very very little. it's supposed to be at 2.454, so it's off by 40 ppm, but firmly in place

    just checked. CONT_WAVE=1 PLL_LOCK=1 gives you this

  16. 25. sij

    ah, time to answer my own question if PLL_LOCK=1, it doesn't actually transmit any useful data. look at this. this isn't GMSK, this is crap.

    the question is. the datasheet, in no uncertain terms, tells that it must never transmit for more than 4 ms. the PLL_LOCK bit is documented as "Only used in test." why? it makes the device much more useful. /cc

    okay, i have a really fascinating question here the datasheet for nRF24L01(+) says that it under no circumstances can transmit at 100% duty cycle, because it unlocks TX PLL when it starts transmitting (left) it also has a bit called PLL_LOCK that makes it not do that (right);
