<awygle> is this Boat Hell
<daveshah> mithro: awesome
<pie__> meh, hungarian has some crappy translations for some terms
<pie__> yield strength is translated as flow threshold
<whitequark> that's kind of accurate in a weird way
<pie__> well, sure i guess

<pie__> at least...i *think* its yield strngth
<pie__> ugh damnit well good thing i looked it up because im not sure anymore
<pie__> something about the elastic limit
<pie__> ah ok that 0.2% figure seems to match, so its the offset yield strength
* pie__ 's heuristics arent _total_ crap \o/

<rqou> whitequark why are you building a gbc video capture device? seems very unlike you
<whitequark> rqou: abadidea said she doesn't have anything to capture it with
<whitequark> i mean, none exist
<whitequark> or maybe USED to exist
<rqou> who is that?
<rqou> i mean, i also say a lot of things but you don't end up helping me build them :P :P
<whitequark> that's cuz u can build them urself
<rqou> and this person can't?
<etrig> how much commonality with original gameboy?
<whitequark> etrig: the display is totally different
<whitequark> the monochrome one is a weird shift register, the color one is basically tft
<rqou> afaict still "generic parallel lcd interface, just poke around for hsync/vsync"
<whitequark> i mean the interface, the display isnt tft i think
<whitequark> no it isn't
<rqou> it isn't?
<whitequark> it has DATA0/DATA1
<whitequark> and it's logically a shift register with a weird way to issue commands like shift row
<rqou> ok
<rqou> doesn't sound too bad to figure out
<etrig> whitequark: I see- your image using the wrong clock edge reminded of an image here: https://github.com/svendahlstrand/game-boy-lcd-sniffing
<rqou> the classic way to RE these is to somehow get the device to display solid colors and the poke around with a logic analyzer for a few hours
<rqou> apparently whitequark didn't even need that first step
<whitequark> rqou: nah
<whitequark> i found the service manual with the schematic
<rqou> heh that makes things much easier
<whitequark> then i typed the pin names into google and it turns out sharp makes lcds with that interface for like two decades
<whitequark> the specific one isnt documented but who cares
<rqou> what does this person want this for?
<whitequark> and that was unnecessary
<whitequark> because then i poked the pixel clock and realized it's actually enough
<whitequark> it's disabled during blanking intervals
<whitequark> i just use a timer to detect vblank
<whitequark> what i dont understand though.
<whitequark> is why do i have digital noise on the *entire* red channel and *only* red channel
<whitequark> this doesn't make any goddamn sense, the pins are scrambled so if i had noise on some particular part of the cable it'd be all over the channels
<whitequark> abadidea wants to record... speedruns... of pokemon crystal? i think?
<rqou> what
<rqou> why can't they use the classic hack? gameboy player into a crappy analog capture card
<whitequark> gameboy player?
<rqou> yeah
<whitequark> whats that
<rqou> the weird addon for the GameCube that allows playing gb/gba games
<whitequark> idk
<rqou> basically has a gba cpu crammed into it with a glue asic that captures video and shoves it into the gamecube expansion port
<rqou> btw for bonus fun, buying an Gameboy player is pretty cheap on ebay nowadays, but buying the disk needed to boot it up is expensive af :P
<whitequark> maybe that's why
<rqou> because the disk is tiny and have all gotten lost
<rqou> thanks DRM
<rqou> hmm, was abadidea originally in tech? her birbsite profile seems like a "burned out of tech" profile
<whitequark> yes
<whitequark> she didn't burn out exactly
<whitequark> she uh... gained a pretty awful disease
<whitequark> no one seems quite sure what exactly it is but it's hyperacusis to the extent that the US healthcare system actually accepts that it's a disability
<rqou> oh huh, that sucks
<whitequark> why do I have 4500 Hz noise I wonder
<whitequark> very consistent too
<qu1j0t3> yeah i remember when that happened to 0xabad
<qu1j0t3> :<
* qu1j0t3 is longtime follower
<kc8apf> rqou: hmm. Gameboy player hardware sounds like a curious bit of hardware to tinker with. *Adds to potential project list*
