@ModalMotors @soil_owner @Rich_Pluta @BicameralMoid Got it, but still not a "non-rare-earth motor" in strict definition.

@taylor_stevan @soil_owner @Rich_Pluta @BicameralMoid Sm is a light-rare-earth and abundantly available outside of china. There is a significant difference between light-rare-earth and heavy-rare-earth, like neodymium and dysprosium. Full non-rare-earth is with Niron Magnetics.

Just ran into Modal Motors. Non-rare earth electric motors for drones and robotics. Similar costs to Chinese motors, all U.S.-sourced. Incredible.

@ModalMotors @soil_owner @Rich_Pluta @BicameralMoid As I know, Sm is a rare-earth metal, then how's the motor rare-earth metal free?

@soil_owner @Rich_Pluta @BicameralMoid Spec sheet coming soon the team is finalizing it. SmFeN. We have more than one supplier as every company should. 60 30 10 rule. We do custom motor development currently. OTS coming 2027.

The @LeRobotHF team is studying the @UnitreeRobotics G1 today in case you have any questions or fun stuff you want us to try!

@sumitdotml @JuanIsidro Nice screen! When I was looking for a new one, this was also on my list and watched pretty good reviews about it!

@JuanIsidro if you look close enough you can see the mounted clamp haha
this is Dell S3225QS, a 4K 32 inch monitor
I got it since my previous monitor’s screen cracked a little and I couldn’t focus properly. I’d been planning on getting a bigger screen for a while, so thought it was time

@IterIntellectus Considering the existing superconductors working principle, by analysing all the known elements, describe the exact method how a room temperature superconductor material can be created. Also consider the ISS microgravity as a possible environment to create it.

@taylor_stevan @MikePFrank @cqcqcqdx In 6 2.7v caps in series, so 17.1v, given the fast discharge rates of supercaps this would be a bad day. It wouldn't kill you, but it wouldn't be "nothing".

@mazeincoding Rename it to openwound with some salt and it will be fine. Joke aside, I'm excited about your project, now I heard about it for the first time

they owned opencut.org and this site is completely down now

hey @elonmusk can you add a feature where if an account hasn’t been active for > 10 years, anyone can claim the username at a price? thank you

@MikePFrank @cqcqcqdx What happens when I touch my tongue on the terminals?

@levelsio There's a nature paper on the topic nature.com/articles/s4417…

@natemcgrady I was actually coding like this yesterday, so nothing

@elonmusk Additionally car makers are planning to use enclosed brakes on ev's to contain brake dust and prevent the brakes from rusting due to low usage

@xlrndo @boxcardavid @BenderDrummer I was thinking the same before opening your answer. 💯 agree. 10+ years ago I saw a robot where they used two computer mice dragged on the ground to track the robot position precisely
English
@boxcardavid @BenderDrummer This sounds like the sensor for an optical mouse (i.e., all of them these days). Not too many pixels, but runs at thousands of Hz and can track just about any surface a few millimeters away.

Measuring the position of a spinning thing with a big hole in the middle is a persistent and annoying problem.
I think a lot about this motor where they just made the magnets too long and put an analog Hall sensor on the side. It’s so inelegant and simple and stupid, I love it.

So, uh... now the question is how do I get the absolute rotor position with a hollow shaft? Plot twist: without breaking the bank and getting an AksIM-2-price-point encoder. Reminder: I need 12x of these 😭💸

@blhack this is the only thing that looks like a microcontroller i can see on the board, the knob just runs into what looks like a pot

i guess i'm doing a toaster design thread now
