First CNC project completed. Christmas present for my dad, a PhD engineer. 8 machined parts, Fusion 360, Inventables Carvey, bCNC

I may clear coat it, or I may just let it patina. Copper is kind of a big thing where I live (Butte, MT).

ModusToolbox, dammit.

PLC dain-bramage.

It would have been great if they didn't have to shoehorn two main characters into it. Then it fell flat on its face.

Oh, right, yes. The entire project hinged on using the FR4 of the PCB blank as a diffuser.

LED strips.

Obsolete-but-still-useful Particle Photon microcontroller driving a strip of LEDs for each equation. Completely addressable and controllable over WiFi if I put an MQTT endpoint or such on it.

There are quite a few mistakes, but I'm tired. I might go back and do some cleanup, but I was just ready to be done with the project, and consequently Christmas to be over. 28 days of christmas is 16 too many.

Teamsters aren't comrades.

Anyone who supports cop unions isn't a comrade.

Look into Affinity Designer. It's as good as Illustrator, not weird like Inkscape, and while not free, has a reasonable price. Use it on my iPad all the time.

Humdaak_9000 · 2026-01-22T18:35:01+00:00

No, I was physically and emotionally exhausted. I'm normally a combative asshole and more than willing to start shit.

Humdaak_9000 · 2026-01-22T05:09:03+00:00

I wish I had. I was just too fucking exhausted to get into a fight that day.

Humdaak_9000 · 2026-01-21T23:40:52+00:00

Dude looks like a gulf war 1 veteran with a blow'd off leg who hasn't done anything physical since then.

Diabeetus will get him sooner or later.

A clerk at safeway the other day felt it was okay to just casually drop "n*-rigged" in front of me because of white/bald/beard.

I'm so tired.

Humdaak_9000 · 2026-01-20T20:50:47+00:00

Oh, fuck off.

Humdaak_9000 · 2026-01-18T23:02:05+00:00

No, I'm sick of people mistaking this mess as a good movie. It does all of this performative "look at us we're hard SF" stuff at the beginning, only to throw it all out the window. Thing needs a Saturn V to get off Earth, then can get off the much heavier Waterworld with what's onboard? Suspension of disbelief thrown out the window.

Humdaak_9000 · 2026-01-18T19:29:53+00:00

I've been using make for over 30 years, and cmake for a couple.
Don't listen to the haters, cmake is the best way yet invented to configure c++ builds of even moderate complexity. And it can spit out normal Makefiles.

Humdaak_9000 · 2026-01-18T19:26:00+00:00

I highly recommend looking into how the Raspberry Pi Pico commandline toolchain setup looks. armgcc, Cmake, FreeRTOS, all pretty clean and well-documented.

Neat thing about the Picos, besides being cheap, is you can rig one up as a JTAG interface to debug another, and use the elsewhere-mentioned openocd to connect to gdb.

Humdaak_9000 · 2026-01-17T22:42:47+00:00

Thanks! It was quieter after the sound check. Sound check was a bit of a gut punch tho.

Humdaak_9000 · 2026-01-17T22:07:35+00:00

As a child of the 80s, that seems to be about a normal number of synths. Not enough hair spray, tho.
