GMO is not inherently bad but how it's currently used is to make plants more pesticide or herbicide resistant and it also limits biodiversity which leaves major crops subject to higher risk of being wiped out by a single disease. For example a variety of bannana was entirely wiped out from a disease because the bananas were basically just clones of eachother. GMOs are also made to be sterile which while is good in the sense it can't escape into the wild it has the downside it means it's essentially a monopoly. I'd recomend watching the documentary Seed: The Untold Story. They talk about the loss of biodiversity and how GMO companies like Monsanto fuck farmers over and the use of harmful pesticides. There also needs proper testing for safety of each GMO or cloned plants (which im unsure if simple clones count as GMOs or not) because the decrease in diversity of their genes makes it more similar to a medical product though I think same of non GMO foods but they usually have at least slightly better biodiversity so it's a little less significant. Hydroponic farming is where the future is at. You can have farm land in skyscrapers essentially. As for things that can't be hydroponically grown farm land is often very inefficiently used. Often everything is seporated from eachother but more efficient use of land would be farming multiple plants along side eachother. For example a shade loving plant under a fruit tree. It also needs to be considered what is grown and to what quantity. Letting the market decide everything isn't a good approach but fully collective farming also is too hard to manage which is why it doesn't often do so well err aside from the fact of trade secrets being kept away from the public. OOn top of that safer more targeted pesticidies need used where needed though one advantage of hydroponics is if things are grown in a controlled environment pesticides may not even be needed at all which is better than safer targeted pesticides because it cuts back production of another product. Additionally a controlled environment allows for increased yields whether or not GMOs are used. Then of course the source of energy needs consideration. There are so many factors that contribute to envionment and health that go into production of food and other products .
I haven't read anything about Aboform used in 3D printing yet I've only read of cellulose plastic used which doesn't appear very good visually like it can't do high detail well from the picture I saw. I assume Arboform (liquid wood) can be used in 3D printing since it can be injection moulded. PLA isn't exactly biodegradable that takes at least 100 years. It actually has to be processed in an industrial composter (only like 117 iirc exist in the US) which can take three months or a home composter in six months. PLA increases soil acidity and water acidity. In water this causes out of control algae growth. PLA also usually is made from GMO corn which often has pesticides used. PLA is safer than petroleum based plastics for home printing though because the fumes are less toxic of levels. Also keep in mind these are corn crops crops need land so PLA and many bioplastics can contribute to deforestation though PLA also can be made from algae iirc but problem there is water usage.
That site I linked if you missed it has "316L Steel" available to print in and I would assume it's already sintered before they send the prints to you.
I'm actually more and more getting tempting to build a kiln from dirt and clay i find on my property just so i can do something lol
I am hoping Arboform gets used more widespread and in filaments soon since it's only plastic I am aware of that is biodegradable without screwing up soil and water supplies (I hope) at least as far as I know and it's also burnable. Looks wood like as well. Part of what keeps me from getting a 3D printer is ones that do metal tend to be too expensive and the ones using plastic I wouldn't feel happy with something bad for the environment.
but thank you so much for your help really!!
Cutting sheet metal requires no special expensive tools. You only need a dremel tool or drill and what's called a jewelers saw that holds very fragile replacable saw blades on it. Will drive you nuts how many times the blade breaks and you need safety goggles to use with it because they go flying off. Also mini files and varrying grades of sandpaper. That's not all but it's the minimum. If you have a blowtorch then jewellery solder and flux as well. Im not sure if a soldering iron would work on jeweller solder ive never tried. If you want to make rings you need a smooth steel rod of correct size (but that's improvision the real tool is specifically for ring making and is semi cone shapped with markings of sizes on it) and use a mallet to bend it over then solder the ends together. There also is a way without solder you just drill a hole in scenter which is how coin rings are made but i never tried before. . I've just been too depressed to try to get ahold of this stuff. I did jewellery making only in a class in school in past outside that I only did hemp necklaces prior. Using the wire you have you could wrap it around a nice gem or polished rock and twist a loop to make a sort of necklace.
I wish I had a kiln but very expensive to buy and probably just to run and to build a fire kiln like some people do I dont have an ideal spot to even try because I do not have a spot clear of trees and grass though I have plenty of land but I don't think the soil is rich in clay so it would be difficult to build using only dirt. I've only used a kiln before back in school in the past for a ceramics class but some places have publicly usable kilns for a fee I think. It would be difficult for making functional objects using that metal clay stuff because it would shrink a little during firing i imagine so you would have to upscale everything a few percentile and nothing will ever be totally precise unless you're very precise in mixture and temperatures. It's mainly for making sculptures and jewellery. I only had found about it recently when I discovered it randomly after I was breifly resesrching if it's possible to cheaply 3D print metal and found some 3D printers use this metal clay which wouldn't be all too complicated to build with right knowhow so I dont know a lot on how it turns out sculpting with this stuff and firing it. Sand casting makes more sense for building parts and there are plenty of tutorials on YouTube specifically for part building and I've seen other unusual methods like making a mould using gelatin then using that to make a plaster cast..... or if cost effective you could just go through a 3D printing company to do it. Yes you dont have to have a 3D printer to 3D print (i sound like a spambot) . Go on materials list and it tells what is good for functional parts various synthetics and metals are available. Go on the sample models so you can get a rough idea what the prices are. It appears they have a minimum pricing so it's better for objects not too small. Prices arent fantastic but not horrible either. Seems not too much more expensive than premade parts if you stick to cheaper materials.

I'm not sure if UV cams use their own UV source or just rely on what is there already. UV damage shows up as dark sploches like freckles but not visible under normal visible light but can appear later if enough damage occurs. UV cams are used by criminal forensics to find where a victim has been beaten or held tightly where no visible wound is visible due to it not being severe enough or too late or too early to be visible. You also can detect trace metal deposits on skin with a UV light. Yeah inflamation shows up as a localized hot spot on thermal cams. If it's a vein inflamed the vein shows up hot for example.
Like how some fruits and flowers glow? Snakes have a third eye on their head basically if i recall right. UV can reveal hematomas and UV skin damage later of which can asses skin cancer risk. IR can show inflamation in the body and to some degree cancer.
Is that those type of night vision that look high contrast that are used for hunting and I'm assuming military?
Yeah I know normal glass is already like quartz. Hm yes apparently sapphire is one of the types used in IR cams. Seems different types are used for different wavelengths. There also is zinc sulfide, zinc selenide, germanium, calcium fluoride, and silicon. Apparently UV lenses are fused quartz, fused silica, sapphire, magnesium fluoride, aluminum fluoride etc... I was just interested in near IR and UV photography. If I wanted full thermal I would just buy one since it's unlikely I could easily make one any cheaper though would be useful to have.
There is some FLIR you can get for around $200 it's just one you attach to a smart phone. Also there is a dev kit by Sparkfun that has FLIR around that price but it's only like a 80×80 resolution. All the thermal camera cores I found you have to contact the company with your info to request information such as prices.
So you're saying you think a simple near infared camera can be modified to be borderline medium wave IR?
At some point I may have one of my DSLRs converted to a full spectrum cam which is extremely simple process of just removing a filter and attaching a lense filter to block visible light to use it as an IR cam or a UV cam. I think it requires long exposure times though. Though that's setting aside quality. To get quality requires a special camera lense made of quartz I believe it was. I've also only heard of this being done for IR I think it can't do very good UV. Something to do with digital cam sensors not being sensitive enough to UV.
Do you know much about thermal cameras? I mean medium and long wave IR not short wave IR. Because I somehow got an anon that was planning in building a smart mirror using my suggestion of adding thermography for medical use and it's the blind leading the blind.
Oh okay. Mentioning a guitar amp reminds me how I still wish I could play guitar or some other instrument.
I guess that makes more sense. Why in pairs though? Is it a redundancy to reduce packet loss?
I vaguely recall it being used on a site i used to watch random stuff on occasion. Think it was called Sputnik One which just streamed random anime stuff seemingly mainly from Manga Studios for some reason. I think i probably have some stuff i saw there i cant even recall the name of to ad to my list.
It's backed up so much I lost track at this point what I even cared about haha well even if I give up hope which I mostly have sometimes it feels and watch stuff prematurely there always is sharing favourites with someone but those always change based on mood and memory which is why i dont have favs on my profile listed plus just avoiding people that talk shit about others tastes.
Oh I see. I thought at first you meant connecting an external source of music and just playing it through the circuitry and I was questioning how that even would work. If it is just the audio device being used for it's intent that makes more sense.
Why is it 4 wires anyway? In my mind what would make sense is three primaries and one for contrast or white levels i mean excluding audio.
There has been a few shows I've been intentionally sitting on hoping some day to watch with a lover for whatever reason. I guess I figured it would be nice to have something I know is supposed to be good and not have it be a second or third viewing while it's someone else's first. Why does RealMedia sound familiar but forgetable. That's not that annoying Real One Player ithat a lot of sites used was it?
