  • I'm pretty good at hunting and gathering. Back before my broken neck and back, I was super into wanting to buy some remote place in the Appalachians and pseudo homestead. I have messed with many of the required skills. I wanted a place in the mountains with a year round creek for a water wheel, building a foundry and forge, along with a manual machine shop. I was into what I could do using junk from pick-a-part type junk yards. People often only think of parts for whatever low end car, but if you actually have a fundamental understanding of cars and the various technologies in different applications, a junk yard gives tremendous access to industrial technology for many types of machines and equipment. Junk yards are not setup for that kind of thing either. A little bit of flattery and flirting with a cashier goes a very long way when none of the collection of parts on your cart have legitimate prices on the menu.

    Even with my disability now, I could probably survive in the wild by trapping game and some minor gardening if the population was low enough and I was in a decent location compared to where/when I live now in the era of the 50 year mortgage fuckwit dystopia.

  • What is your meta thought process like when drawing your own handwriting?

    Jump

  • Some people have a more steady hand than others. Like I can do professional sign lettering, but it is super difficult and slow for me to do because I do not have very steady hands.

    I can paint stuff like candies (dye based paints that get infinitely darker with overlapping), and pearls, that are both shot basically blind by intuition and muscle memory, but I cannot see hand written lettering and what I want to project onto the page, in advance of actually drawing it. I'm more like a bushwhacker with a machete most of the time.

  • I tend to lack the patience to make mine nice. It requires a lot of focus. There must be a fundamental difference with people that have very nice natural handwriting. I'm curious what that might be and how others perceive themselves in that space.

    Even with graphics on cars and motorcycles I rough sketched in several light strokes before establishing a more solid line. I want to write in a similar way. I almost have a subconscious mindset like each letter should be a draft with revisions or something. I do not have a vision of how I want the letter to look so I just slop something down like a rough draft. Then it is functionally readable, and I can't easily refine it so I move on.

    Maybe it was that day in school when the teacher made me chose what hand to write with. It bugged me so much that neither hand was dominant and no matter how much the teacher insisted that I have a dominant hand, neither felt any different, so eventually she decided for me that I was right handed... and I still have not forgiven her.

    That is the moment in school when most of us selected our handedness. That is an impactful moment in life. In terms of competitive sports it may define your potential in many areas. It leads down this path of the psychology of writing.

  • [Blog] If fiber infused material is abrasive to soft metals, it may be useful as a sanding medium

    Jump

  • So the trick to sanding longer with abrasives is wet sanding. In addition, in automotive work, a drop of Palmolive dish soap is added to a bucket of water. This addition makes a huge difference.

    Overall, the principal of like polishes like is important. In abstract, polish is just fine abrasion. Like your finger prints are around 5k-7k grit equivalent. Rub something long enough and you will both polish and abrade it the same as this grit. The oils in your skin are the polishing agent.

    I have played around with 10k grit wet sanding and then machine polishing with a light compound where places I rested my hand showed minor variations after stripping any oils and fillers with wax and grease remover (solvent).

    I can think of several aspects to increase the complexity here. One could add inserts into the outer vibrating shell. These could be any materials.

    I think the bigger issue will actually be the distance between the object and the shell. You see, the size of the random orbital action is the product of two concentric circles. In the pro automotive world, these are pneumatically driven. There are several models available with different properties related to this motion and the internal balance of the mechanism. Within this range of actuation, it is critical that abrasion does not follow a path of repetition. I think this likely means the shell must be larger than the radius of the largest of these two circles or maybe a more complicated size larger than the combination of overlapping radii including their central connection point. This should enable the part to move within the range of random sanding action. That range means the sanding is over a larger area.

    The best shell is likely one with gaps similar to a DA sander with ports for dust collection.

    Very little of any fiber touches the actual nozzle during printing. The actual fiber size used in filament is far far smaller than what most people imagine. It is only the waste dust from the production and processing of carbon fiber. All actual fibers of any useful length are sold in industry for use in composites. There are continuous fiber printers, but that is not at all related to what is used in 3d printing. If you actually look at the data from people testing materials, fiber infused materials are always weaker. They print better because they are breaking up the polymer bonds. Lots of people jump on the buzzword thinking it is technomagic mor betterer but do not pay attention to the details. If the fiber had any length to it, it would clog like crazy because a long bunch of fibers distributed in 1.75mm crammed into 0.4mm is never going to happen. It is just like a dust additive that happens to be available and is compatible. So it should be well distributed throughout. With ABS a wipe of acetone should help too, if left to completely flash off the solvent for a week or more. That needs to be super limited though. Acetone tends to get retained in bad bad ways with ABS. It is a massive no no to use in automotive applications.

  • Most people's routers are already up 24/7.

    We should be able to do our own DNS. Who cares if it is on the wider clearweb. You are paying for an IP address with your internet connection. If you are running a server with verified hardware and signed code, all we need is a half dozen nodes mirroring our own DNS. There must be a backup proxy for the few terrible providers that cause issues with IP. The addresses are not static, but they do not change very often. At worse, you hit a manual button to reset or wait 10 minutes before the DNS updates.

Come back to (sadistic masochism where everyone goes through the motions and no one is intelligent or real or cares about anyone as evidenced by their actions) kingdom hall. (be like the rest of us that never paid any attention to the conspiracy level nonsensical explanation of the reason why Jehovah's Witnesses exist in the Revelations book.)

    I don't know, it might be fun to improvise against some fresh hate materials. The same thing all the time gets old but polished responses.

  • It is not about the people that already host. It is about enabling many more by giving them an option to buy a path of least resistance. In exchange, it creates a potential revenue source in a completely untapped demographic. The subscription/donations demographic is like a very unique and niche market. The vast majority of people do not exist within that space. Most people do not have the financial stability to engage like this. It is not that they are unable to accumulate adequate funds, it is that their pay fluctuates over time and their baseline constraints are far more stressful than spending from times of surplus and opportunity. Catering only to those with such surplus and gatekeeping the complexity of self hosting is massively limiting adoption.

    The rule in managing a chain of retail stores is that, no matter how you select products to stock in stores, it is impossible to only select products that will all sell on one platform. How you manage the overburden always determines your long term success. You must employ other platforms and demographics to prioritize the mobility of cash flow.

    Similarly but inverted, this place has a slice of all demographics. Efforts tailored to the various subsets should tap entirely new potential. A fool imagines they can convert the unstable poor*'r* into a reliable stable income source via donations. Someone like myself has means but not a situation that is compatible. If I have some tangible thing to purchase, I can make that happen. I do not have any subscriptions in life for anything at all. Heck, I won't even shop on any of my devices I use regularly because I only buy what I intend to go looking to purchase with intent. That is not common, but what is common are spontaneous people that need time to align their finances with their desires. That person is likely to dread paying $5 every month compared to $250 in May when they get a couple thousand dollars on a tax return. Expecting the public to float the stability is stupid. That is not how the real world works. Real businesses always float the overhead. I'm talking about how to free the masses to self host everything for the cost of a nice router spent once with no techno leet filter.
