first impressions of the Lego smart brick, before I do any actual tearing down: wow, I forgot how good they are at working with plastic.

@whitequark hey @zhuowei does this match anything you found in the LEGO Smart Brick app? Or does the app have a newer firmware version?

@nicolas17 @whitequark @zhuowei for everyone else who got invested now, I think you're referring to this thread: https://notnow.dev/objects/cccfc047-da57-444a-be6f-63a5a766bcf7

@whitequark cpu_top is clearly a Verilog module name lmao

[whitequark@social.treehouse.systems]

here's how the flash was mounted in its natural environment, in absence of feline predators

the SPI bus seems to be shared with something else & they're definitely using ViP

[whitequark@social.treehouse.systems]

@wren6991 yep!

[artemist@social.mildlyfunctional.gay]

@whitequark very important pad

[whitequark@social.treehouse.systems]

alright let's dump the ARC chip now

@whitequark What are you using to dump the chips?

[mlp@defcon.social]

@azonenberg @whitequark @gsuberland @ldcd @ftg
When Microchip first produced a PIC32 it was built around MIPS (I was at HI-TECH Software at the time - we had a compiler targeting it). Later they acquired Atmel and renamed the (ARM-based) SAM series "PIC32..."

[azonenberg@ioc.exchange]

@mlp @whitequark @gsuberland @ldcd @ftg yes I'm talking about their embedded controllers for laptops etc not general purposes MCUs.

Real PIC32 is mips, not the rebranded SAMs sold under the pic32 brand

@whitequark Cool! Thank you.

[triplef@bildung.social]

@whitequark but the most important question remains unanswered: Can you make it play actual star wars sounds instead of the unintelligible gibberish now?

[whitequark@social.treehouse.systems]

not my best work but it should do the trick

feat. comically big q-tip

[dev@discuss.systems]

@whitequark oh lol I thought it was a cat’s paw

[whitequark@social.treehouse.systems]

@dev that would be a really small cat
