  • I have no confidence it will work or last. I’m not committing to anything either, but at a minimum I need the flattest image possible, meaning a square lens to object from a distance where perspective distortion is minimized. The largest camera sensor (silicon die) will produce the flattest image with less perspective distortion. Each image must contain a known measurement, such as a little machinist’s ruler or other. The point here is that the lines of known measurement must be as close to single pixel accurate as possible. I will not take the time to straiten or correct for errors, - if I have the time and feel like making something. The result will likely be ugly and might not work or last. I need to know the angles and sizes of those protrusions to utilize them like a dovetail. I do not trust anyone’s measurements, especially my own, and I have no desire to dial you up for the ‘measure thrice print twice, measure once unfinished dunce’ - rule. I need the Cartesian planes of X, Y, and Z, (right, front, top) at a minimum.

    I probably do not have time within my project, but if I’m bored and waiting on a long print, maybe.




  • The cheapest fans available often have a lot of injection molded plastic that squeezes out of the gaps of the metal mold when the plastic parts are formed. Removing this may help some.

    The cheapest fans now come with the small motor shaft embedded into the frame with a tiny ball of metal formed at the end of the shaft. The ball is what prevents the shaft and fan blade portion from coming out of the housing. This type of bearing and retention cause more friction than a design that uses a bushing and a small plastic retainer ring. They type with the retainer ring are usually floating in the magnetic field. The little plastic retainer ring on the shaft end is only present in cases where the fan is dropped causing more force than the magnetic field will hold onto. If a person such as yourself, presses on this type of fan at the fan blade hub, you will feel the magnetic field and see the hub deflect and then return to the center of the field. Spinning it will feel frictionless. With the ball shaft type, there is little deflection and it feels like a bit more friction when comparing two side by side.

    With the ball shaft type, most of the noise will be coming from the friction and transmitted through the body of the enclosure. If you isolate the fan with some damping between it and the enclosure it will reduce the noise considerably. Damping the enclosure, and adding rubber feet between any table or surface may also help.


  • Preach about the primitive stupidity of wasteful industrial technology and the stone age of silicon. Biology is the ultimate technology. The Neolithic is to us what we are to the age when the age of discovery is over and all of science is a fully constrained engineering corpus. This is the age of biology. At this technological stage, civilization is possible at stellar lifetimes and beyond, unlike the present where critical scarce resources are fully commercially depleted within a century. The ultimate technology is fully integrated into the elemental cycles it exists within.

    The only thing holding us back is investment into discovery within a social framework of meritocratic hierarchy. Gross inherited wealth is the terminal cancer of civilizations. Intelligence is not hereditary and the impotence is incapable of managing or filtering innovation and progress. Anything beyond a trust fund for an upper middle-class lifestyle is treason against country and future.

    Take for instance space exploration. All of the missions are about military engineering and have little to no basis in science altruism, or progressing the future. If anyone had even a tiny fraction of sense, we would be putting everything into the recovery of a single m-type asteroid. Any of these fragments of differentiated planetesimal cores contains more rare mineral wealth than all of what humans have accessed in the Holocene. We live on the flux, the dross, the garbage that floats to the top when gravity has pulled everything we value within this gravity prison of resource scarcity. Everything we have is the result of the sparse junk that fell to the surface later than the last phase of molten Earth; those outer objects that still contain diverse wealth. We could go right out there and pick one of our choosing. We are the Neolithic fools that never travel one valley over and discover all the resources and technology of the Han Chinese. That one objective eclipses all human wealth in a decade. Instead, we are territorial toddlers bedazzled by the colors on our toy stick’s fabric, and no better than chimpanzees mobbing to rape and pillage, with the mass mytho disorder of collective imaginary friends. The biggest businesses in our world of the present are no more that prophets selling technological singularity and infinite energy scams the same as the ancients pedaling Zeus and Apollo. There is nowhere to go down in truth; only to peek behind a façade to see nothing has changed.


  • Depends on the system. Typically, the older systems do not work like this. The GPS satellites only transmit a signal that contains their location information and the time. The device must collect several of these signals and then use trigonometry to calculate your real location in time and position. Yes there are relativistic effects due to the distance to the satellites and gravity.

    For instance, in home lab electrical engineering, if a person wants a really good reference clock but cannot afford a cesium atomic reference, they can use a relatively cheap GPS system to build a referenced oscillator that is disciplined by the reference clock on these satellites. I think they are cesium too, but it has been awhile since Dave Jones made YT uploads on the eevblog about it. A Garmin bicycle computer is another example. It is triangulating the signals and plotting periodic waypoints with some basic averaging.

    That said, WiFi routers and cellular towers are possible to use for similar triangulation. Maybe check out Hak5 if they are still around. It has been awhile since I looked them up, but they used to make pen testing red team stuff that will infer much about vulnerabilities.










  • Gross inherited wealth is the societal version of terminal cancer. It is the actual underlying problem that has gone unsolved. Intelligence is not hereditary in humans. No amount of money can replace meritocratic hierarchy at scale. As long as that issue goes unaddressed, this place will crash and burn. Anything beyond an upper middle-class trust for life must be forfeit. That one change eliminates every problem person you know by name.



  • Check DNS logs. Discord is proprietary undocumented garbage that connects to dozens of raw IP addresses that have no documentation, rhyme, or reasoning. You have no clue what or who is connected in that mess of garbage, or why they are there.

    It is about like, I’m going to give you access to a phone, a special phone, it just works.

    It is a prison phone. You are in prison when you use it… technically. But you don’t really “see” the “place”. The other inmates are all around you. They see you, but you don’t see them. Never mind that though, the phone just works. Lots of people love that phone. Nobody asks questions. Just use the phone and pay no attention to all the rest. It will be fine.

    Business model? Viability? Never mind all of that. Don’t ask questions like that. The numbers do not add up in the slightest. That is the magic of prisons. Justice costs a lot, but it is worth it right. Magic phone is easy. Ask no questions. Expect no answers. Totally normal, everyone is doing it.

    The whole thing is a mass of clueless zombie morons that ask no questions and have no idea who what or why they are connected to with all those raw IP addresses. They all give trust blindly without accountability or understanding.




  • I’m in a microclimate that is even more unique than most of SoCal. You would have to visit to really understand it. I would not have believed it until I moved here. The temp where I live is 10-20 degrees Fahrenheit different than the surrounding area even just a few miles away. It only exists within a mile or so of the ocean. Riding a bike everywhere for years was quite fun because the weather always gets better the closer I get to home. It could be in the low 40’s F at night in Irvine, but it will be 55-60 F in San Clemente in the winter. It may be nearly 100 F in Mission Viejo in Summer, but it will still be 75 F in San Clemente. It has to do with the water, mountains, and how this area is situated at the edge of the LA Basin. It causes the wind patterns to be favorable here across both major regional weather patterns. If you go diving here, it also becomes obvious. There are three major thermoclines even at recreational diving depths and the first one hits hard at just a couple meters down. The cold water is why there are never hurricanes here. Any disturbances of the surface mixes the thermoclines and prevents building strong storms. When the air gets too hot, this area is covered in a marine layer at night because of the water temperature and that is what keeps it much cooler. San Clemente is where that phenomenon starts. There are actually cheesy little tourist shirts sold about the place in Peru that is supposedly the only other location with the same microclimate in the world.
