as a former professional skater, I can say the technique here immediately reminds me of upper body positioning in speed skating. specifically the way the arms move across the body while the hips and torso rotate underneath them In skating that goofy motion helps manage the lateral shift of the center of mass and counter the angular momentum created by each leg it’s interesting is that the robot wasn’t explicitly taught to run this way the gait emerged through reinforcement learning as it searched for a faster, more stable and less thermally demanding way to move. yet it is not copying a speed skater It seems like two very different systems arrived at a similar solution to the same basic dynamics problem Convergent biomechanics ™ lol video is of an old competitor of mine who is currently crushing everyone in skating at the moment GUZMAN

old surface molding part where i became obsessed with having perfect surface normals and G2-G4 continuity if you understood this you should probably be working and not on your phone

be honest how long would it have taken you to come up with this mechanism

these clankers are getting much better than I thought You can just link your models to OpenFoam lol.

Week 1 of the JT15D teardown is done! We pulled the accessory gearbox, got into the external engine lines, and started getting a real feel for what 10+ years in a warehouse does to an engine. Every fitting was a fight, every seal was fused, and I learned pretty quickly that this teardown is going to demand a lot more patience than I expected. One thing I did not anticipate is how long quality videos actually take to produce. Between the teardown sessions, the scanning, the documentation, and everything else happening on this project, there is just not enough time right now to film and edit the videos I actually want to make. So for now I am capturing as much footage as I can, and once the teardown is complete I plan to go back through everything and put together videos with a bit more production quality behind them. Massive thank you to Jim Belosic Maxim Lobovsky (more on that soon) and every single person who contributed to the crowdfund. NONE of this would have been possible without all of you all who decided to support this project, so thank you! An on the ITAR questions, I ran it by an ip attorney and they cant find any issues with doing this, But we are still going through the proper CJ paperwork to have hard evidence that this engine has ZERO compliance issues. This is only the beginning.

So we just got this thing on casters so we can move it around the shop easily Our preliminary damage report is that it doesn’t actually seem that damaged The previous owner said that he had it for a citation 500 and they decided to get rid of the airplane so the last time this engine ran was in 2013 however, one of the compressor blades came off and went partially through the engine However, it didn’t go through to the turbine so it’s somewhere in here. We just have to find where it is. But in theory, it shouldn’t take too much to get this thing running for right now we’re just gonna be focusing on the teardown and we won’t know it’s ultimate state until it’s fully disassembled But so far things are looking good

a mutual here on x asked me how professionals design wings for aircraft and drones in cad, so I put together a quick, high-level overview of how this process is generally done, and showed how the 3d model is constructed if anyone wants a high-level or technical breakdown of anything aircraft or jet engine-related, just shoot me a dm. if I’m knowledgeable on it, I’d be happy to make a video explaining it at the level of complexity you’re comfortable with. same goes for any powder bed metal 3d printing processes, specifically dmls and electron beam sintering
