  • So birds can get their wings broken by sudden gusts while aloft. Without accounting for size (reynolds number) and reaction speed - a fly would suffer a similar fate.

    But I’ve seen videos of insects and/or flies hit with directed blasts of air. They react very, very quickly by adjusting orientation and shape. If a fly tucks fast enough it might survive the aerodynamic forces due to its reaction speed, and be left to the fate of where it’s path goes while it slows to a flyable speed.

    And size matters. What seems to us a thin and uniform body of air gas for them is thicker and rippling with waves of density and speed. The wrong placement might kill them with pure shear or high pressure, but I suspect they have the ability to surf those waves as well, and maybe even use them to steer through extreme conditions.


  • I have been paid for and paid for CAD and other impacted engineering products including software. AI is unfair… How?

    I can see some issues with copyright, and I acknowledge it will upset economies. But being able to ‘automate’ photo to 3d, and so many other tools that enable me so much to do things that wouldn’t have happened before, it’s unimaginable to many around me. Change is scary, strap in.


  • I tried Meshy and Trellis and Hitem. Next I’ll try printmon.

    Hitem has the best free option and portrait mode. Made some great busts.

    Meshy looked great if cartoony with its model 6, but only let me download from model 4, which was a surprise and made monsters.

    Trellis was in between and I ran out of huggingface tokens quickly.

    I’d use hitem all day but not interested in paid subscriptions for my passing hobby. Hoping Bambu is handy with printmon again, though I expect it may be proprietary.

    Also, all needed some cleanup, Bambu could fix slice and print but not adjust details and cuts. Started with Blender but the interface is hard for a CAD person. Switched to using Meshmixer, which works great, and just using Bambu to do a final fix of the stl before slice. Make solid is a helpful tool in Meshmixer if you get a good looking but imperfect stl, but you have to be careful to avoid losing detail.

    The underfunded school, or its expensive insurance will pay, raising rates and eroding the service of public education further.

    I found out here in CA public schools are paying several percent of total budget to cover liability from the past where kids were harmed.

    These are not for profit, these are not businesses. When they pay, the taxpayers pay, and the kids lose service.

    But whatever, she got hers. Big smile.



  • Precision and volume are the key metrics. They have precision here, but it looks like they won’t get volume.

    “E-beam lithography machines cannot produce chips at a large scale like Dutch company ASML’s DUV and EUV lithography systems, but they excel in the testing stage of production, offering high-precision circuit patterning and design flexibility. Priced lower than imported machines, Xizhi can pattern circuit lines as narrow as 8 nanometres, with a positioning accuracy of 0.6 nanometres – matching international standards.”
