  • Not an IP lawyer, (those people are EXPENSIVE), It’s perhaps less about the idea than it is about the process to get there. And yes the patent office does make mistakes at times. It’s just expensive and hard to correct those mistakes because it generally takes a judge to do so. And I’m willing to bet this patent is valid in the EU also due reciprocity agreements and trade deals. It would take an EU judge to invalidate the patent, which would cost as much as doing so in the US.

    One thing that I have learned over the years is that no patent is actually really valid until a judge bangs a gavel and says yea or nay to the patent, (I’ve held a couple). Until then, it pretty much just a piece of ass-wipe paper you can wavy around and hopefully scare off others that don’t have the money or want to spend the money to challenge the patent.

    At some point the toys would fail, they were 8 and 9 year olds after all, but it could take a month or more in the hands of children. I was pretty shocked. I did have a paper wad cannon that had a spring that was printed all in one inside the barrel. The first few had issues with the compression spring breaking when over compressed by the kids. But a bit of a redesign of the spring by making it beefier, it not only lasted nearly the whole school year but the kids got more range. Much to the other teachers and parents disappointment.

    I’ve Printed LOTS of PLA living hinges and even springs. They do work just fine for the limited to moderate cycles they last. I’ve printed 100’s of toy catapults and other small toys in PLA and then handed them out to 8 and 9 year old children. They held up amazingly well under that abuse.







  • Yes, dictatorships and monarchies sometimes have a petition process, but they tend only to pay lip service. Not because they care, they will do as they please becaue they have the power-- hence a dictatorship. See: North Korea or a few countries in the middle east. Imagine trying to petition the Afghani government as a gay or worse, a trans person.

    Governments of any kind are large and ponderous beasts. They cannot change direction as easily as you would like. And like it or not, there are rules and processes that must be followed to make changes. And those things are in place to provide continuity in government and protections to the populace at large. Imagine how much more damage trump could have done without those processes and rules. Imagine what he could do if he wins again after the last SCOTUS ruling.

    Like it or not, Biden is bound by a lawful treaty ratified and codified by congress a long time ago. He cannot undo that treaty on a whim. Only congress can do that at this point. Make your changes there. And representatives and senators are local elections and not national. Best of all, YOU could be the change you want. Don’t expect someone else to do it for you.




  • Concrete lathes are far from a new idea. During WW1, the US needed more lathes than we had. It could take years for a cast iron casting to age enough sitting outside before you could do the final machining to actually build a lathe.

    So concrete was tried as a substitute for cast iron. It has some good properties, it cures quickly, is rigid enough, and dampens vibrations pretty well. The downsides are you require a physically larger machine that takes up more floor space, and they are difficult to move making resale difficult, and they don’t last as long in that usage, so they aren’t cheaper in the long run.

    Concrete lathes had their day and quickly died out to be forgotten.
