I'm experimenting with sensors on #librem5 (but should work on #linuxphones after tweaks). So far I have compass and step counter. github.com:pavelmachek/Espruino.git

@jmlich @GOKUSHRM IIRC OnePlus 6 and 6T is pretty similar. OnePlus 6 is a tiny bit better, because it has 3.5" jack.

Got compass to work on #librem5, so far it needs to be "flat". Code is in tui/bwatch/magcali.js.

@ozzelot @violenteastcoastcity Just use LibreOffice. You can not fix Word, and fixing Microsoft would be even harder.

@xChaos @askihk @tymoty @sibrosan S temihle prirovnanimi bych byl velmi opatrny. Nekde jinde jste takhle udelal uvahu ze hranice pozorovatelneho vesmiru by mela mit teplotu nula kelvinu; to rozhodne neni samozrejme (a myslim ze to tak neni).

@xChaos @askihk @tymoty @sibrosan Tak sci-fi si rad prectu, ale...

Ranny vesmir a vzdaleny vesmir je prece to same, ne? To je myslim celkem uznavane.

A podle me je uznavane i to ze se Zeme proti CMB pohybuje, a robot souhlasi.

A jasne, soucasna kosmologie ma nejake problemy, ale "vidime moc galaxii v rannem vesmiru" myslim neni jedna z nich, uvitam odkaz.

--

Pohybuje se zeme proti CMB?

ChatGPT said:
Ano, Země (resp. Sluneční soustava) se vůči reliktnímu záření (CMB) pohybuje. To se projevuje dipólovou anisotropií CMB – jedno směřování vesmíru se jeví o něco teplejší a opačné směřování o něco chladnější kvůli Dopplerovu jevu.

Konkrétně:

Rychlost Sluneční soustavy vůči CMB je asi 370 km/s.

Směr pohybu je zhruba směrem k souhvězdí Raka (Leo).

Tento pohyb nezávisí na rotaci Země kolem Slunce nebo na rotaci Země kolem své osy, ty mají mnohem menší efekt (~30 km/s pro oběh kolem Slunce).

Takže ano, Země/Sluneční soustava není v klidu vůči CMB – CMB nám vlastně poskytuje „absolutní“ kosmologické referenční rámce“.

@xChaos @askihk @tymoty @sibrosan ??? ??? ?..? Ja myslel ze "pozorovatelny vesmir" je velmi dobre definovany pojem? https://en.wikipedia.org/wiki/Observable_universe . A vidite tady nejake galaxie? https://en.wikipedia.org/wiki/Cosmic_microwave_background Ja ne, ale vas post chapu tak, ze by tam mely byt -- CMB je rude posunuty ranny vesmir. Soucasna kosmologie ma nejake problemy, ale jine nez zminujete...

@askihk @sibrosan @xChaos @tymoty Tady asi doporucim neco jako "PBS spacetime" na yt? O vesmiru toho vime dost, ale "utvar" bych asi nepouzil, a bylo by potreba rozlisovat pozorovatelny vesmir.. No a pak tam bude nejaka filozofie jestli casti vesmiru ktere nemuzem pozorovat jeste tedy jsou nas vesmir a tak. Proste je to celkem slozite :-).

I'm playing with angular velocity sensor on #librem5. I can get some data from sysfs, and they show hw is working, but interface is not fast enough for anything useful. I did not get triggering / buffered mode to work so far. Code is at git@github.com:pavelmachek/Espruino.git .

Reply to @z3ntu@fosstodon.org
@z3ntu Ok, so apparently it is possible to buy Fairphone 5 and 6 new here, for similar prices (cca EUR600). Second-hand Fairphone 5 may be available for ~EUR400, and new Fairphone 4 may be available for ~EUR300.

Having main camera available with open-source drivers sounds very cool and may be reason for Fairphone 4 ... unless same is true for the newer models...?
