Has anyone ever done something similar to that? I'm thinking to fixing my late grandma's village house, but my main concern is its proximity to a busy highway that's half a kilometer away through just a field and this muffled sound of traffic can get annoying.

The thickest, tallest concrete wall you can build, with a row of even taller trees on the inside of the wall.

I'd probably do double or triple glaze windows first
If that's not enough then id do professionally blown insulation in your walls.

If that's still not enough, then id start looking at walls. Around here in California they are just cinderblock walls like 12' tall. Sometimes two walls in parallel. It's so far away I don't know how effective it would be unless it was quite long.

Alright so /sci/ still hasn't answered my question, so I guess I'll ask you guys instead. Are there any electric speakers that produce enough force to lift their own weight off the ground using sound?

this is not a question for /sci/. they are busy estimating their earning potential, while you are doing applied research.

if you succeed taylor swift will pay you millions.

Yes, but only for a short time, and only once.
Just hook them up to 10,000 volts DC.

My friend was throwing away a demijohn because it was sitting in her yard for years and it's dirtier than hell.
I been trying everything I can think of to scrub all the dirt and grime from the inside walls.
Do you know any chemicals that eat away at dirt without scrubbing?
I can't get anything in there that's abrasive enough to clean the inside.

Add sand, water, and dishsoap then shake it.

I love that shape.

You can use vinegar. Fill it up, forget it for a month. Use it after cleaning with normal elbow grease. I have tons of carboys and demijohns. I got a lot of old bottles left out in the forest at a dump dated around 1920-1950. I've had to buy aluminum rods from the local hardware store and make my own tools that can fit inside them for easy cleaning. Mineral build up had to be cleaned with a weak acid.

Start your schoolwork immediately. Always try to be ahead; the moment your done with one assignment move on to the next; practice, practice, practice. Drop everything else and make school your number 1 priority. Come to terms with the fact that your procrastination is rooted in your fear of failing. Life is nothing but failure; might as well spend it trying to achieve something hard and challenging.
>>
the fuck are you doing on 4chan if you're grades are shit? Go study
>>
>>1239385
1. do your homework
2. use your schoolbooks
3. if someone fucks with you, let him/her hit you first, then destroy the person fast and ugly
4. looks matter
5. weed only after you are at least 19
6. have friends
7. don't give a shit. its just school, only grades matter there

Anyone try the Openbuilds minimill? Looking for something that can cut plastic (ABS, HDPE, POM) with accuracy under 0.1mm

Saw on a forum that the minimill supposedly has decent accuracy. Anyone here try it or other <$1000 desktop mills?

there are some pretty cheap (sub 300 dollar) laser cutters and 3d printers on aliexpress that you could easily modify to fit a dremel or a router to cut plastic.
>>
>>1237336
No
3d printers and laser cutters arent built with lateral forces in mind, they simply wont be stiff enough to chew through material without flexing and walking making your cut inaccurate.

>>1237294
The axis movements in all of these small machines are pretty accurate nowadays, cheap little controller boards with proper steppers.

It looks stiff enough to cut through some plastic if you have a stout enough spindle
>>
I've been looking into this from the perspective of being as cheap as possible to play around with. This guy has some interesting cnc machines he's built from basic materials. Probably not what OP is looking for, but interesting for /diy/ tinkering.

Anyone here ever made their own plate armor? Seems straightforward enough if you don't mind the hours and hours of hammering flat sheet metal into something wearable.

Yeah, and making clothes is just cutting and sewing fabric, and framing a house is just cutting wood and hammering nails.

on the bright side the cracked slab isn't a major problem since it's just a driveway and not a foundation

So what's stopping you from putting a washer and dryer in there?

Might as well convert it into a landfill.

>>1241929

City requires a new inspection for new sewer drains. Have to pass before I move appliances in.

>>1241931

yes, which is going to be a fun experience because I can't even move a storage trailer in because I have a bunch of nonfunctional (as in not starting or rolling) vehicles in front of the garage doorway.

So I have a window A/C unit, but my windows open side-to-side, not top-down. For the last few Summers I've just had a piece of plywood cut to cover the hole, but next Summer I'm planning to get a new A/C (which is actually in the mail, on it's way here), and want a more permanent solution for the gap.

I'm thinking of making something with a thin strip of insulation in the middle, two pieces of plywood on either side, and then a nice wood trim along the edges. The inside "wall" would be painted to match the walls and trim, respectively. I'm also thinking of putting a handle on the inside (to make inserting and removing it each season easier), and screwing it into the window.

Has anybody come across a similar situation, where an A/C doesn't fit the orientation of the window? What was your solution?

Have a similar problem, but I've just got a 'portable' AC unit.
The hose thing does not fucking fit or stay in the window what so ever.

Really the solution is always the same:
Build a bracket that fits in the window, and holds the thing in there.
Insulate well around edges with foam tape or such.
Use foam board sandwiched between plywood (with something weather resistant on the outside) to fill large gaps as in OP's pic.

you could buy a small split system. my cuckshed has a Daiken.
