  • 150mm^2 obviously (tho only for 400A). Don’t know that I’ve ever seen 800 amp powerlock, I guess they would be 240mm^2 and above.

    I think they are talking about more industrial/commercial applications that use ceeforms or powerlock for 1 or 3 phase: 16A, 32A, 63A, 125A (I know, we were so close). Anything over that is powerlock, and I don’t know if any single phase powerlock.









  • A CNC shop wouldn’t start because someone decides “I want to start a CNC shop”.

    It would start cause some guy has a mill and a lathe for hobby stuff, and does some work for a mate or a local business.
    And then gets more work, and gets work that requires CNC, and gets more work than 1 person can deal with, and then needs more machines and machinists and CAD tech and designers and so on.

    Yeh, a business could get something from PCBway or whatever. But maybe they need it by the end of the day, or maybe they need an opinion on something, or maybe they can’t do the actual technical document production but can provide some measurements and a rough sketch.

    Apply that to anything.
    The UK Army’s L96A1 was made by 3 guys in a shed.

    The Ministry of Defence wanted Accuracy International to submit an entry, but when they won handily, suddenly the three men in Mr Walls’ shed were charged with producing over 1200 rifles and all of a sudden needed to prove they could make that many weapons.

    What they did was rent out a workshop for a day and filled it with all of the guns they had made in the shed up to that point, claimed the rest of the staff were out to lunch and later found out when they went to eat with the requisitions lieutenants that the inspection was purely to ensure the operation was not just three men in a shed.





  • I’d start with learning some networking basics.
    Subnets, default gateways, DNS, routes, VLANs.

    Then get another computer to install proxmox on.
    Learn VMs, SSH, firewalls, basically Linux. Probably VPNs as well.

    Then set up a VM and play with docker & docker-compose.

    And that’s most of the tooling to be able to self host anything. A VM with docker, set up the docker compose of what you want, boom: done.
    Some projects are more of a “full of” kinda thing (like home assistant), which would be its own VM







  • after tracing a rare bacterium in the city’s reclaimed water to Goat Systems LLC, the entity Meta uses to build its Cheyenne campus. In a notice reported by Cowboy State Daily, the Board said Goat Systems was in significant noncompliance for discharging water carrying Cupriavidus gilardii, a metal-resistant bacterium that interfered with two water reclamation plants and pushed the reuse system offline for months of cleanup.

    I am guessing the fact that the reclamation and reuse systems required months of offline-cleanup after a rare “metal-resistant” bacteria was detected suggests that their processing abilities are tailored towards common harmful bacteria, with detection to alert issues from uncommon bacteria.

    Say a pest exterminator is used to using an air rifle to deal with a rat problem (it’s a shit example, but work with me here). Turning up to a rat infestation that also has bears with only an air rifle probably means running away and coming back with a new technique.
