Thanks bro, will post there.

As a canadian trap line enthusiast, I am a living resource. Is there anything specific you want to know or are you more looking to pack reference material?

If the latter is true you could look around at outfitters like cabelas for reference guides instead of bringing text books. Hauling that weight would really piss you off, trust me.

I'm no engineer but it seems like you'd need some kind of reinforcement to keep it from collapsing on itself from the weight

But again, I'm retarded so, you know, probably get a second opinion.

call up the company that makes the cast concrete pipes you want to buy

>>1035592
think they pretty solid, could probably stack a few - start cutting 'windows, and doorframes' into them, maybe problematic but.

bought 4 of these (slighttyy smaller) once as foundation 'feet' for something else - was surprisingly cheap, way cheaper than building shit form scratch.

In case there was any confusion on my idea, as the car drives it enough "wind" would go through fan to spin it and generate charge with simple magnetic generator, dunno much about electronics but its just an idea

>>1034635

Your idea would work OP, however you're better off getting the electrical flow from a generator attached to the engine. You can't escape the second law of thermodynamics.

You would be better off inventing a coating that goes on the car that produces electricity from the friction of air. That is all energy lost during travel.

cars already have something that works better called an alternator

If you want free metal you need to ask some local fabricators if they have any cut stock lying around or cut rebar. Sometimes they'll let you have it. For practice go get a block of sculpey and roll into round or whatever you want to practice on then put it in the freezer over night. "frozen" sculpey behaves the same way as hot steel. You can work on your strikes and see how things will turn out before wasting any metal.

>>1032629
>free steel.
Steal parts off your neighbors' cars.

I'm lucky that I work at a fab shop and my boss lets us have whatever we want out of the drop pile.

I haven't started working any metal yet but my stepdad has an 80lb anvil and I'm saving up to build/buy a forge when I move into my own place again.

additional questions:

how much land does one need to make a living off it?

pic related is the immediate surroundings

considering that there is farm land close to it, the odds for my land to be arable should be quite good, right?

I hear there are lots of boar in the area, but I don't have a hunting lincense yet. I understand national and local regulations apply, but is it generally possible at all to hunt boar on three acres? Like, if I were to go there, license and gun and all, set up a tent and then shoot a boar on my own property, would that be alright?

since my questions mostly relate to what one might call "homesteading" I but it on /diy/ rather than /out/. hope that's OK

I don't know how big an acre is but I bet it isn't enough.
I live here on the other side of the baltic and I believe the economics are the same. Basically you can't do shit without equipment and that again is too expensive...
I rent here a house while I build my own and our landlord is a farmer. He says that before the EU-money he has a loss of something between 100 and 200 euros per hectare. If i remember correctly he has a bit over 100 hectares of cultivable land. And he has all the equipment from before, tractors, harvesters, drying silos and the whole shebang. If your property is not field then you need serious equipment to make it growable!

So hard to make economically feasible I'd say. You need to grow something that pays well. And weed can be grown in a closet.

Keep it for fun, not for profit as it's hard.

>>1024013
Lumber is cheap. SO cheap. Building the house you've described would be a much more expensive endeavor.

Fires and storms are rarities one can insure against.

Don't get me wrong, I much prefer the German method here, but Americans will always prioritize being able to build too many, too-big houses for low materials cost.

>>1024013
A lot of people do build houses out of premium materials

With that said, its just cheaper and faster to do it that way.
Nobody wants to live in a old outdated house.
There are a lot of neighborhoods with old brick houses that are still perfectly functional, but nobody wants to live in them. It costs just as much to build a brand new house than it would to retrofit the old hazard to be to code.

Its not uncommon to buy an old house for its plot and completely demolish it. Just throw up a brand new completely state of the art house.

It allows the middle class to build houses and keeps neighborhoods from going to shit.

Forced obsolescence.

I dunno about T&G siding but for my time and exterior (stucco) I'd rather take out the interior walls than the exterior. YOu'll have to rip off the outer sheathing as well (osb/plywood) if you go from the outside which you shouldn't do to the whole wall at once because it is structural. You'll also lose your weatherproofing if you get sidetracked or there is a freak storm.

I'd go with removing the interior walls. Honestly hanging drywall is super easy, mudding is only slightly more difficult, as is painting.

You can also 'blow in' insulation with a rental machine from home despot (which does a mediocre job), or get a pro installer to do who will drive up with a truck/van/semi mounted blower and stuff your walls with 3.5 lbs/cu ft which is the maximum you can achieve without your walls bursting.

Monitoring this thread (on phone so no lizard pic) because I too have a 50's vintage house. I KNOW there is no insulation in mine. Interested to hear any anons' opinion on blown in insulation. Seems like a pain in the ass drilling a hole between all the studs then patching. And does it fuck with the electrical system at all? I've heard good and bad about it, like it can settle and then you're back to basically no insulation. I agree that inside would be easier, just wondering how much... Also OP, if you have the old two wire electrical system (like me) and you rip out the the walls, it would be a great time to upgrade to three wire.

Not a total hijack, this info is pertinent to OP's question, but sorry none the less.

>>1038224
If you get the 3.5lb insulation it won't settle because it can't. You can't DIY it though because the blower is too big to rent. In that case your contractor should warn you if electrical would be effected. I can't imagine it would be unless you had knob and tube.

Nothing is going to be able to survive

>>1038161
Dang it

What about displaying information with a projection?

First off, what purpose will the hud serve? Information for the oven? What will the touch controls do? Control the oven?

First, ovens can get hot enough to reflow solder. That could cause serious issues for any pcb that needs to be inside the oven to pull this off. Some electronics don't like heat either, like ICs and fets, which will absolutely be included in anything you use for this.

Second, you won't be able to use that glass for touchscreen controls. You won't be able to replace it with a different type of glass either. And even if you could, clear touch screen controllers are just now starting to see use in consumer devices, it's new and expensive technology.

Third, if you're intention is to control the fridge and view info for it, you'll only be able to see info the stove is designed to track. Internal temperature and clock for example. To get that somewhere else you would need to modify the board for the stove, finding the data output, routing it to something that can actually interpret the data, and then outputting the data to the hud. Same thing, you'll only be able to make it do things it's capable of doing, at most you could set up something that will turn the oven off if a timer goes off and the door doesn't open for a couple minutes, or to change temperature automatically after a certain amount of time, but that'd be something separate and extra you'd have to work to achieve.

also any tiny tiny bits of guidance in the correct direction are appreciated. would an audio amp chip (LM386) be better than an op amp for any reason? all of my chips are tested and salvaged from audio gear

Literally first google image search result for "white noise circuit"

2A is well above what you need for this.

>>1038136
so i just checked my audio amp chip and my gf stepped on it and it lost all of it's pins. would an op amp with the same gain work?

>>1037987
Since you obviously ran to the internet for advice, the logical answer is pleather.

Here's the room it'll probably go in.

1. Sell it to somebody who cares about antiques
2. Buy something that isn't an antique so you can do whatever the fuck with it


Alternatively, shoot yourself for even considering to fuck with any kind of antique furniture.

Loose 1/2

Never heard of it

Best to research heavily online. Finn have been the major US hydro-seeders for a long time.

You can find landscaper forums and help him figure the best bang for the buck. If buying used don't be afraid to drive long distance for a deal and do study the fuck out of the specific model you are considering.

Business licenses are a local deal. County courthouse should have some info.

Thanks for the sage advice, anon - I'll pass it along.

Basically something like this where I can just apply a small amount of voltage and current and look at it on an oscilloscope.

I have a CS degree but we never even talked about this kind of stuff, mostly data structs and java shit. Thanks

It depends on everything else. To begin with, do you really need a circuit which produces the sine of a random input voltage or do you just want an oscillator with sine output?

If you insist on building a sine/sinc block, then the old-fashioned way was the piece wice-linear approximation using diode or analog switch clippers.
A bit more modern way would be an ADC + ROM + DAC.
IIRC Analog Devices also had an IC long time ago for producing sine output. I think it used the aforementioned technique internally.

>>1037711
Well really I just wanted one to better understand the applications of sin(x)/x and since I can already tell a sin wave generator is easier to make I would rather make a sin(x)/x generator with random/arbitrary x value as x approaches 0 on the x axis.

I don't understand some of the things you are saying though like wice-linear approximation and I
would rather do it the old old fashioned way.

I like your charger as long as it puts out.

If I take those sinks off, would that die?

They make "portable" a/c systems, they just sit up on the floor, rather than in a window, you just gotta pipe the heat out a window, look up indoor a/c
