You cannot put DRM in stepper motors. This law is dumb.

Can't stop those 3D printer pens, either. Someone could one day be literal when they say they are gonna draw a weapon.
Hey now, don't give them any ideas... Next thing you know all stepper motors will require daily gustapo inspection before use by a robocop placed in every home.
You can buy whole kits to build your own, the capacity to control what is made with the is about as much as if you tried to ban someone with a table saw from building a birdhouse.
tried to ban someone with a table saw from building a birdhouse.
Thats a perfectly succinct analogy.
Pretty sure you could make a gun too, which is the point of this 3D printer thing
And like what about other CNC machines?
I like that California is on the frontier of many tech laws, but this and the age thing are particularly dumb lately
I made an AR15 with a hobby drill press from Lowes at work. Give me a hunk of metal, a micrometer and a file and I can make you a gun.
Or worse.
And that is illegal, as it should be. The efficacy of a law has nothing to do with whether it's moral.
It's like saying "we don't have the manpower to police murder effectively, so we are gonna legalize murder". It's a fundamental misunderstanding of what the law is fucking for.
No its not illegal:

You can't make a machine gun or other items on the NFA list though.
A homemade AR15 is completely legal to be made at the federal level.
The rest of your comment is off base.
I'm pretty sure that's already illegal in CA
I think at this point it easier to list what isn't illegal in California.
Are the laws sound and moral? That's the only important metric, it doesn't matter how many laws you have. It's not like you go, oh shit, we have to keep it under a hundred thousand so now we can't make new laws around AI data centers because that's just too many!
lol you again, who decides whats "moral"?
And WTF are you bringing data centers into a post about 3D printing and California's draconian laws?
Neat, I would've assumed you'd need a mill or a lathe, not just a drill press. Kinda want to know how to do it myself, since I own the former but not either of the latter.
It won't be accurate or be a long baller w/o a lathe to make a rifled barrel. Not that you couldn't mke a barrel with hand tools, it just would be very difficult.
And like others have said, only the lower receiver is the controlled item. You goto Brownels and can buy 98% of an AR w/o a background check.
The upper reciever is the load bearing part on an Armalite, but it's also not the regulated part. The lower receiver is, and all you need for that is a box that holds the trigger components in vaguely the right place, a hole that lines up the magazine, a hole to stick the buffer tube into at the back, and some way to nail the upper receiver to it.
You could carve an AR lower out of wood if you were dedicated enough.

Nobody tell California about a nail combined with certain diameters of pipe, because guess what, those can become guns too.
zip guns, lets bring in slam fired shotguns.
Never doubt the ingenuity of man killing other men.
Thank god we have laws prohibiting and enforcing it then.
No we don't, check the ppost with this link

I can make guns all day long and you can't do anything about it.

If I'm not mistaken, this DOES cover ALL manufacturing devices, and if it doesn't, it will in the future

Everyone unplug from the internet?
Bingo, back to the SneakerNet.

You can still connect it to your LAN without giving it internet access.
Or I don't and I have no worries as I trust NOTHING.
I know that a Samsung teevee disconnected from the internet will try and use another appliances internet connection if it can. Gotta imagine this is possible in other devices, too.
Last year I started maintaining a MAC address whitelist on the router: if I haven't added it, it doesn't get in or go out. No way in hell I'm putting any household appliance on the allowed list. While an appliance could technically still try to access via an allowed device, they're all phones and tablets and computers with slightly more robust security than the trust me bro levels of an IoT appliance.
Just gotta hope your neighbors don't connect their devices, and that your own can't reach the neighbors.
Can you share more info on this? I'm interested in the technical aspect how this is done, specifically which devices it uses?
For instance, say, a smart speaker, may have Bluetooth and WiFi, but I'm not sure any halfway comprehensive network stack I'd even implemented that could be used as a proxy, let alone autonomously remotely reconfigured to do so.
If memory serves correctly it was another Samsung device it was leveraging which makes more sense. There were other occasions where it had once been attached to WiFi for a firmware update, disconnected and told to forget the network, but attached again to it at least twice. Took the steps to forget the network again and then powered off completely. Subsequent checks show no further connections so far.
I've also heard of devices that scan for open networks in the area to use. It's also possible for them to come with a sim card and use a discounted cell collection, though not sure if any TVs are actually doing that. Could even be a virtual SIM so there's no card to find and potentially just remove/destroy.
