Actual Solidworks assembly in the Quest 3 real time. Some solid bodies, some laser scan meshes, 9 million triangles, steady 90hz, and some shaky hands. This is getting pretty exciting

[Greg Wall @AgitatedPancake]

@BellikOzan Fair. I agree that propulsion seems necessary for anything high enough to interact with any of the orbital shells, and beyond

[Greg Wall @AgitatedPancake]

@BellikOzan That is, unless the dummy Starlink contraption can act as a kick stage and add delta v before deploying those payloads, then they could become a concern again. Hmm

[Greg Wall @AgitatedPancake]

Would it really be necessary though? The Starlink deployment altitude is far below any of the active Starlink orbital shells. And If they launch via a dummy Starlink like Starfall, and it's the last in the dispenser, as soon as the rest of the Starlinks that got dispensed start orbit raising they're completely safe from any passive payloads behind them

It's getting easier and easier to bring cool tube designs to life, this is rad.

[OSH Cut, Inc. @OSHCutInc]

This machine is seriously so cool.

OSH Cut makes it easy to design and order custom tube bends online—from CAD to finished parts. Upload your design, choose your material and bend options, and let us handle the rest.

Custom tube bending. Made simple. Built to fit.

@i2cjak They know they've got some catching up to do

@itslueul Grok 4.7 should be roughly on par with Opus 5.0, not 5.1. Better in some ways, worse in others. We need to fix multimodal performance.

Grok 4.8 will be a noticeable improvement.

Grok 4.9 is probably Astra/Fable class.

Grok 5 maybe better than anything. We shall see.

@CJHandmer That was a great read, thanks for sharing! What an adventure. I’m amazed at how deep those lakes are for their size

[Greg Wall @AgitatedPancake]

@JohnGetchel Not this time, though I visited on a previous trip. Between the two long trips, we saw an incredible amount of what the area has to offer. So cool out there!

[Greg Wall @AgitatedPancake]

@JohnGetchel Right on. This one was between Panamint Springs and Ballarat, and seemed far less traveled than some other areas we explored

[Greg Wall @AgitatedPancake]

@Xaraphim I think so too. I’ve been tinkering with a VR tubing tool, and it’s amazing how we’re able to build full feature sets these days. Can’t imagine what we’ll see in a year or two

[Greg Wall @AgitatedPancake]

@Alwurts Thanks, it's WebXR. I just got the VR headset recently so I've been excited to tinker and see how far I can take it for actual tube design work

[Greg Wall @AgitatedPancake]

Working on tube corner node handling. I can choose priority for each tube depending on what’s needed, and all cuts are normalized for 3 axis laser cutting. Nodes can become bends as well

[Greg Wall @AgitatedPancake]

@Tutrifour That's like early 3d printers where moving the bed fast manually could backfeed and power on the screens haha

[Greg Wall @AgitatedPancake]

It's definitely one of those manufacturing methods that has always had a high perceived barrier to entry. But I think this new era of rapid software iteration is going to cure a lot of that intimidation.

I'm glad you're sticking with it, because it's awesome and people just need to see how easy it can be!

[Greg Wall @AgitatedPancake]

@CalebChamberla6 Heck yeah! Your machine collision detection is the critical final required step before actually manufacturing from these drawings. Ideally I will export from here so I could upload straight to OSHCut for that final DFM pass against your actual machinery, and then order!

[Greg Wall @AgitatedPancake]

Added some manufacturing rules to this tube tool including hard limits for minimum straight sections on either side of bends as well as dimensions. Getting there

[Greg Wall @AgitatedPancake]

@BellikOzan There's always the possibility of a rocky start for these new rockets, and there will probably be pain, but the demand for that conventional medium lift launch seems like it'll stay healthy for a decent while (hopefully)

[Greg Wall @AgitatedPancake]

I'm a bit torn about how to interpret it. I see what you're saying as well, everything revolves around the constellations now and Amazon would benefit from more F9 LEO launches in the meantime with the lack of pace from their other launch providers.

But the medium lift dollars that won't be flying on F9 any more seem like they'll be enough to support multiple of these up and coming launch companies long enough to build up their space systems and diversify a bit like Rocket Lab has done. And that could change the face of long term US space industry, compared to fighting for pennies and seeing who survived if F9 stayed fully active.

Maybe it's purely a side effect, but it seems like it will have good long term effects after the short term squeeze on satellite operators
