@s1gmanet Water is good (though you could say water is part of "food"). There are lots of very important feeder elements (energy, metals/materials, fertilizer), but in theory some new technology could be invented tomorrow that would make them unnecessary.

@timbot water. you left out water my guy. everything else on the list is irrelevant if you cant drink safely. also id argue energy isnt just an enabler its a hard requirement for medicine production

If SHTF, a nation needs to be able to produce: - Food - Clothing - Shelter - Weapons - Medicine Anything else? I left "technology", "energy", "transportation", and "infrastructure" off the list because those are things that enable the above, rather than essentials themselves.

@davidliuxyz I have this exact setup for my cat's litter box

collab robots are so cheap now i can make it scoop aluminum chips from the back of the cnc. imagine adding a mobile base - the potential

@_baldtires Don't hurt the poor robot!

Fuck you

@samanfarid I laser / apply cut vinyl to everything I make. Branding is fun.

The good thing about being an industrialist is that there are lots of opportunities for signage 🫡

@campedersen Sounds like alien technology

+ fpga + 48v + 🤔

@zanehengsperger That's a sweet Vibe Table

it’s a shame to see these old WW2 era factories turn into apartments, offices, rave event centers not this one…

@fabworks_guy Yessir Cheap, durable, and pretty precise!

@timbot Is that an frc April tag lol

We're calibrating

@observie "using a printless calibration jig - the floor" 🤣🤣🤣

Joint space aligned throughout the entire pipeline: CAD, URDF, MuJoCo, Rust. The zero position is now the middle of every joint's range of motion, and all 12 joints are calibrated together using a printless calibration jig - the floor - by setting controller offsets.

@embedrapp Don't forget @dirtman 's cheap robot arm!

@timbot the iFixit kit and the space heater under the bench... this is a real engineering lab.

@KennethCassel Shop robots. Maybe eventually autonomous terraforming robots. Or autonomous killing machines. 🤷‍♂️😉

@timbot what’re yall making?

@jaiselsingh Doing motor / encoder / IMU / AMCL calibration, tuning, and testing using a top-down high quality global shutter camera. All driven by Codex. Gotta generate ground truth somehow! Verification is the new code.

@timbot your one charuco square is bigger than my entire board, what’s this for? 😅

For drone startups, I quote them "crazy eddie" low prices for swiss lathe machined parts because I love what they are doing and want them to win big I don't even care about making a profit honestly we need to get as many startups off the ground in this space as possible.

@masch_services The Blackfly I bought is only 1.6MP, so at 8' there can be detail lost with an AprilTag much smaller than this one (6.5" square). At least, that's what Gemini calculated out...

@timbot cool! multiple smaller markers (>=3) might be better in my experience

@observie What are the disadvantages of it? It seems like it'd be labor saving, even if it's only a small amount of labor. Maybe less error-prone too.

This calibration jig kinda works, but after trying it once, I'm convinced it isn't worth it. Its advantage is the ability to accurately calibrate the calf joint's zero position. It's nice, but if your motor controller firmware supports setting a position offset, then a full calf calibration jig is moot: it's simply easier to drive the calf to its mechanical limit and configure the controller's position offset. This way, the robot's runtime software would read the middle of the range as zero, exactly as if you used a full calibration jig. The green filament btw is @BambulabGlobal's green PLA Basic, which prints really well.

@stefan_salaices People never heard of a catfish SMH There was even a whole TV series on them
