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.

@kirtai me: i don't have a hacksaw

you: no razor saw?

[kirtai@tech.lgbt]

@whitequark
They're not the same kind of saw

[viss@mastodon.social]

@whitequark its...

a brick

with an arm core, wifi and speakers?

[cfriedt@society.oftrolls.com]

@whitequark

Interesting... I wouldn't do the port myself due to lack of time, but it should be doable.

[danderson@hachyderm.io]

@whitequark Wow they've come a long way since the Mindstorms NXT bricks! I wrote my first embedded stuff on that brick, debugging my LCD driver by beeping out register values one bit at a time. Simpler, more innocent times when I didn't have the tools to hook into the handy JTAG port that was right there.

[whitequark@social.treehouse.systems]

@Viss bluetooth le, but yes

[whitequark@social.treehouse.systems]

connected half of the pads

this is my first time soldering a 0.3mm pitch WLCSP, so it took me a bit to set up the workspace the way that makes it possible, but it's not too bad

@whitequark @migratory

actually the easiest way to get rid of inconvenient abs is acetone. dump ABS in, get highly flammable toxic sludge out.

@whitequark @bob

8-year-old me discovered copper works just fine when attached to a sufficiently large transformer.

much older me is banned from hot tools.

[viss@mastodon.social]

@whitequark hah, wow

[ftg@mastodon.radio]

@ldcd @whitequark
It is quite widespread, even if not visible to end users.
Being in most Intel CPU's and all that.

[doomsey@hachyderm.io]

@whitequark @bob

8 year olds should be allowed nowhere near these. https://dfarq.homeip.net/all-about-the-lionel-zw/

doubly so, two of them, with the knowledge you could run them back-to-back to do interesting things.

[ldcd@social.treehouse.systems]

@ftg @whitequark yeah that's why it's kind of funny, it is simultaneously a very common CPU and a very obscure CPU (ie it's hard to get comprehensive documentation, the devkit is literally an FPGA, etc)

Like they're not lying but they're trying to imply it's a normal CPU to use and be able to program which isn't really true

[whitequark@social.treehouse.systems]

finally done. no shorts and (as far as i can tell under mag) no opens

[gsuberland@chaos.social]

@ldcd @ftg @whitequark I have yet to come across any SoC with an ARC core where the docs weren't partially or fully NDA'd, or at least gated behind a sales call.

[ldcd@social.treehouse.systems]

@gsuberland @ftg @whitequark exactly

[cfriedt@society.oftrolls.com]

@whitequark xtra smol 🤏

[ldcd@social.treehouse.systems]

@gsuberland @ftg @whitequark This is my industry standard very normal CPU core (no you cannot look at)

[rairii@labyrinth.zone]

@gsuberland @ldcd @ftg @whitequark can we blame star fox for this

[ldcd@social.treehouse.systems]

@Rairii @gsuberland @ftg @whitequark a lot of modern problems can probably be blamed on starfox
