2 days ago, libcamera did not really work with itself, or Librem 5. You need auto exposure -> have ARGB8888 data. So I teached ppm saver to write that. And then got AF to work (slowly) on Librem 5. See libcamera list for details.

@jachym @dodo1095zd @elektrofest_cz @Petr90 @RezzaBuh @sesivany A ne, to ze to jde vyjet do nuly vlastne nic neznamena... nebo spis znamena ze cela kapacita neni dostupna.
a) To nijak nemluvi o tom, jestli je baterie vybijena naplno.
b) To uplne vypnuti znamena, ze to zarazil batery management, protoze clanky "hardwarove" nevypnou ale s vybitim se snizuje dostupny proud.

@jachym @dodo1095zd @elektrofest_cz @Petr90 @RezzaBuh @sesivany No to prave jedno neni pokud se snazime extrapolovat chovani baterie do budoucna.

#libcamera Libcamera does not really work with itself, or Librem 5. You need auto exposure. Ok, that means swisp. Good, so now you have ARGB8888 data. Surprise, cam will not save that to ppm (it expects RGB888). Nor will it save it to dng. In full resolution, I get 0.5 fps. In minimum resolution (~768p) I get 8fps. Not great. Hopefully it should be possible to make swisp crop things. Help would be nice. You also need AF. Fortunately there's a patch for that :-).

@CalcProgrammer1 @stovis Librem 5 is another option where HDMI-over-USB should work. And I believe newer OnePlus-es should be able to do that, too.
But... be warned that big monitor needs big resolution and that needs big CPU and big GPU, at least if you want to browse the web.

@sesivany @elektrofest_cz @Petr90 @dodo1095zd @jachym @RezzaBuh Maji ty Tesly LiFePO3? A neni tam nejaky ... trik / podvod typu ze cast kapacity je uzivateli nedostupna takze pak tahle statistika vypada lip?
Kazdopadne bych rad videl neco podobneho v elektronice.

@sesivany @elektrofest_cz @Petr90 @dodo1095zd @jachym @RezzaBuh Takze predpoklad je ze "dnesni" baterie budou mit jeste za 20let rekneme 70% kapacity a ty elektroauta budou pouzitelny? To je podle me sci-fi.

@sesivany @elektrofest_cz @Petr90 @dodo1095zd @jachym @RezzaBuh Ja nevim co jsou "drevni" doby elektromobility. Prvni auta byly elektro, tusim, ted nejakych 120let plus. A jo, vse krome baterie bude bud fungovat nebo opravit. Jestli nekdo vnima na elektromobilu dulezitej motor, tak je to vlastne v pohode auto. Ale ja vnimam jako dulezitou baterii... protoze je to nejdrazsi soucastka.

@RezzaBuh @jachym @sesivany @elektrofest_cz @Petr90 @dodo1095zd Thermal management... Ale ty baterie ho potrebuji i pri skladovani, ze? Takove auto zaparkovane na slunicku. A jasne ze vyrobce ma motivaci lhat "to je stary problem, ten uz je vyreseny"...

@sesivany @elektrofest_cz @Petr90 @dodo1095zd @jachym @RezzaBuh S tim ze se pouzivana baterka poskozuje bych se klidne smiril. Ale snazim se baterie neskladovat ani plne nabite ani plne vybite, presto nevydrzi. Vetsina notebooku je vetsinu doby pripojena k siti, baterie je stejne prvni co odejde.
Pravda je ze LiFePO3 baterie v OLPC se i po letech chova velmi slusne.
Take je pravda ze teplota ma vliv, coz je problem tech notebooku, a ze BMC obvody maji vliv na vydrz baterie. Presto... spalovaci motor z roku 1905 pobezi. Dnesni elektroauto v roce 2125 nikdo ozivit nedokaze.

@etchedpixels @quixoticgeek @ChrisMayLA6 Why is "retaliate" bad option? Seems like prisoner's dilemma to me, and retaliation is crucial there.

@ptesarik @larsmb @trochee And I agree. If company gives out bad advice, they should be responsible. It is scary how little warnings are on chatgpt, for example. And this will only get _worse_ as bots get better. I wonder how many people got hurt because of that ("pizza with glue"?) and how many will...

@sesivany @jachym @dodo1095zd @RezzaBuh @Petr90 @elektrofest_cz Tak za rozdil pokladam, ze motor starne s kilometry ale baterie starne s kilometry a casem. A strasne rad bych videl ty baterie co neco vydrzi v nejakem mobilu / telefonu... nebo uplne nejradeji ve vsech. Je skoda ze z mobilnich zarizeni je za par let elektroodpad, a baterie v tom hrajou velkou roli :-(.
