Board: /diy/

"/diy/ - Do It Yourself" is 4chan's imageboard for DIY/do it yourself projects, home improvement, and makers.

Welcome to /diy/
diy
Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

In this thread we share general experiences and tips on how to make your living situation more efficient, be it in terms of saving money, reducing time waste(less maintenance/upkeep), organization or anything else that may simplify and improve your life

>on saving money
it's not really about the little things like unplugging your phone charger, focus on the main energy drains and commit to more "drastic" changes:
- unless you do some hardcore meal prepping chances are that your fridge is way too big. downsize for a smaller more efficient unit and fill it to the brim if you have to, a full fridge wastes less energy and having a smaller space forces you to be more intentional when shopping so you have to think twice about buying extraneous crap you don't actually need
- wash your clothes in cold water, most of the energy in a washing machine goes toward heating. if you have the room and weather, line dry them outside. both these things also help clothes last much longer
- avoid the range oven, use an air fryer or small convection oven for faster results and a fraction of the energy
- most of the world does just fine without AC. use weather appropriate clothing + an electric blanket in the winter and a fan in the summer

>other stuff
- you would be surprised how much clutter affects your mood. most things don't need to be on display at all times so use closed storage solutions, if you have open shelves they should be filled with storage boxes to keep all the crap out of sight. will also keep your stuff clean and dustfree
- NOTHING improves the a room like a rug. throwing a rug in your living room / kitchen / dinning room / bedroom / bathroom / office will completely change how you perceive and experience the space. just be smart with choosing the right size and style to make the most of it

Just some things of the top of my head. Are there any practices you've implemented at home that made your life better?

Rented a flat for a year.
This is how a shared balcony wall looks like.
I want to heat and sound proof it to some degree, since right now it is pretty much a "cosmetic" wall.
would welcome some advice.
right now my best idea is to just buy some of those car insuluation rubber sheets where you glue one side to your desired area.
Also since as you can see how it looks like ass right now, the solution doesn't have to be pretty

Beach Shelter
E757ECAB-5F09-402B-8BDD-F454B7106168
I’d been looking for an alternative to our falling apart umbrella for a while, and last weekend I saw a few of the Shibumi shelters on the Florida panhandle. The wind was always breezy out there, so that wouldn’t be an issue. And if it were the back could easily be propped up with poles and guy lines.

I looked it up online, and essentially:
>8 yards of fabric sewed into a rectangle with a single channel on one end
>a ~20ft collapsible tent pole
>a piece of rope
>a carry case that doubles as a dead man anchor
That’ll be $270. Seriously, it’s one of the most overpriced pieces of easily DIY’d outdoor gear I’ve ever seen.

I might try making one. Anyone have an alternative?

>hurricane thread
Floridian here. When we bought our house in 2020 it didn't come with the aluminum shutters. Apparently the renters who lived there before we bought it sold them for crack money or some shit. Anyways, I have the mounting points on all the windows but I want to find the cheapest way to do this (it's going to be a heavy hurricane season).

Some options:
>Plexiglass ("storm busters") sold at home depot. Hundred bucks per sheet. Absolutely overpriced.
>plywood - ends up rotting because I don't have room in my garage and I don't have a shed (or room for a shed).
>buy plexiglass sheets from alibaba - this is a viable option, it's significantly cheaper even with shipping. Might take a month or two to get here.
>aluminum shutters - fucking outrageously priced literally over 100 per window to do the according aluminum
>fabric shutters - a viable option and approved for hurricanes, but they just seem kinda gay i dont know much about them or the prices. probably overpriced.

New home build questions

I'm buying a new build house and need a water softener and an underground sprinkler system for the front and back yards. Can any anons help me with the following?
>Size and type of water softener I should get
>Rough estimate on price to install lawn sprinklers
The house is 1300sqft on a 0.43 acre lot in a white(for obvious reasons) suburb. I'm assuming this would leave about 0.2 acres worth of lawn space. I'm still in the permitting stages so I don't have the surveyor blueprint yet but I'm working on getting it from the builder. This is in Florida, on a well, and the builder will be putting in sod for the lawn. See attached floorplan

I want a big dick antenna so I can pick up stations from 60+ miles away, so I can get the random college radio station that plays weird coolwave at night, the indie rock station, classical station etc,

Transformer to arc welder
20240614_130149
I found my father's old arc welder, DIY I guess. It has one transformer with 9 primaries and 8 secondary wires (of which 2 outputs are thick copper wires) and two switches (220V – 0 – 380V and 0-8 switch).
Switches are faulty, transformer is tested as follows:
-All wires are separated from the switch and from each other
-There are 9 red wires, 6 gray and 2 thick uninsulated copper leads to which the main cables for the electrode holder and ground are connected.
-No wire has contact with ground.
-All red wires have mutual continuity (primary of transformer)
-All gray wires have mutual continuity
-Two thick uninsulated copper lines have mutual continuity
-There is no mutual continuity between wires of different colors, nor between any colored wires with thick uninsulated copper conductors.
- The red wires were numbered at the bottom with numbers 1 to 7, two were not numbered and I marked them with 8-9A and 8-9B.
- The gray wires were not numbered and I marked them with numbers 91 to 96.

How to identify the transformer wires to which the input voltage needs to be connected. The moment I enable the input voltage, I can measure the output and sort it by voltage and connect it to the appropriate place on the switch accordingly.
Is this three phase transformer?

Best screws?

>how hard can it be to make a simple screw
And yeah, apparently very hard.
https://www.spax.com/de-de/spax-in-der-praxis/holzbau/characteristics-of-a-spax-wood-screw.html
Explains a lot, but not all. Mostly, not really sure whether to get yellow or silver screws. Obi mostly sells yellows, whereas you get silver online, so I figure silver is the better option.
And of course I technically red to choose the type of screw, depending on the material, but it seems like “universal “ is good enough for most /diy/ uses.

Custom Aquarium Building
RE-OR15--E
Looking into building a custom aquarium out of acrylic at a 30" long, 12" deep, 18" high tank. Based on the info I've found, the general rule is +0.125" thickness for every 6 inches of height on the tank. By that rule, I should be using 0.375", but the acrylic that I already have on-hand from scrap is 0.25". The plan is to frame the aquarium not only top and bottom, but also on every corner with wood, epoxying the outer corners to the wood, using solvent on the acrylic joints, and then sealing the inner corners with silicon.

With all that said, would it be possible to just double-up sheets of acrylic, staggering the joints, to end up with a sort of pseudo 0.5" thickness? That would place it over the 0.375" recommended thickness, and my assumption is that they don't expect the builder to be reinforcing corners as I am, since part of what I read said it's not just about the sheets bowing out from weight, but the joints being thick enough to properly adhere; staggering the joints would create more surface area in multiple directions for the solvent.

Pic somewhat related, but not really. The corners are probably going to be 2x2 or 3x3 with the tank set inward 1" so front and sides are visible.

DIY Side hustle

Hey faggints

I'm in QC and have an engineering degree, but I'm slowly starting to think that it would be nice to have my own production/inspection equipment to make money on the side. Obviously I don't have a crazy ass workshop, only a table, some hand/power tools, fasteners, and a pair of 3d printers, but I feel like there must be people out there who want doohickeys made or some shit formally inspected. I know the initial investment into some mechanical instruments can be quite absurd, but is it wrong to want to be able to produce/evaluate things as an additional source of income here and there? Not sure how far I'd want to go yet, but inspiration would be nice.

Learning How To Tan Hides. Progress Over 3 Attempts
3rd Attempt @ Tanning
1

a mostly failed attempt at brain tanning. wool instantly slipped after "salt pickling" Hide. after fleshing, brain tan was applied. it was gross and ineffective. I will come back to brain technique after I establish some basic concept of process and skills. low grade sheepskin leather for cordage perhaps.

2

chemical tan agent, orange bottle. dry salt, folded, stored in fridge. 3 day process, scraped 2x. it went infinitely better, but the Hide was damaged by fleshing and my 4-legged supervisor attempted a durability inspection. my fault. I had been feeding him meat from the same animal that same day. decent result, but has a hole. there is about a 24" # 30" section that is totally fine. I did not stretch it enough during dry. it is flexible, but rigid. I think I can improve by "post stretching".

3 & 4

same Hide. this one is looking MUCH more promising. 2 days of dry salting, fleshing in-between. Used orange bottle of tanning chemical & hung to dry last night. final dry and stretching now. this evening, I plan to nail it out to a 4x8 plywood. this will help stretch and make a flat flesh side so I can sand it with 120 grit after fully cured. finally, I will "post stretch" it to achieve this magical, theoretical "supple hide" I keep reading aboot.

I brought #3 to work with me today, so I can stretch throughout the day as itfinishes drying. unsure what the ultimate use will be. wife wants some leg and arm warmers for this winter. she works our farm full time, so that is a great use of our animal. the undamaged skin may end up as a rug.

/mcg/ - Microcontroller General: SMD adapter edition
kino
Previous thread:>>xxxxxxx

Here we discuss microcontrollers (MCUs), single board computers (SBCs), and their accessories, such as Atmel mega and tiny AVRs (Arduinos), PICs, ARM boards such as blue/black pill STM32, ESP8266/32s, RP2040, Raspberry Pi, and others.

For general electronics questions (power supplies, level shifting, motor driving, etc.) please ask /ohm/.

>where can I find verified quality microcontrollers and other electronic sensors or parts
digikey.com
mouser.com
arrow.com
newark.com

>but that's too expensive
aliexpress.com (many parts here are fake, particularly specific parts out of stock in the above sites)
lcsc.com

>I need a part that does X and Y, with Z specifications. How can I find it?
use DigiKey's or Octopart's parametric part search. Then purchase from one of the sellers listed above.

>how do I get started with microcontrollers, where should I start?
There is no defined starting point, grab a book and start reading or buy an arduino off ebay/amazon and start messing around. There are a plethora of examples online to get started.

It's another computer chair thread
20240527_174536
Okay, pic related. This shit is about 6 years old. Obviously it's shit, but not only because it's falling apart. It's shit generally, as "gayming chairs" universally are. So, I need another chair. Here are my criteria:
>comfortable
as in, I don't feel like I'm in a hypersleep pod when I try and sit back.
>height
I'm 6' tall. So i need some height. I have also been thoroughly terrified by a thread that discussed the reality of putting a high pressure hydraulic cylinder in a perfect position to fatally sodomize me. I'm also about 170 lbs. So, not fat, which leaves more options open.
>Price
I'm either cheap, or poor. Pick whichever you prefer to believe, the outcome is the same. The piece of shit pic related was about 260 dollars on discount on Amazon. I'm not actually sure how much I'm willing to spend here, I guess just remember that money is an object.

Servo Momentum
an_art
I have a robotic arm like pic related. Basically there is an arm sitting on a pivot, which is a 25kg servo.

The servo moves it fine when its balanced, and moves it fine when it's slow, but overshoots the desired position when moving fast. Not only does it overshoot, but it also bounces back and forward until it stabilizes.

Is there a solution?

> get a better servo
What are the options <$200 that still do 0.17sec/60° (60RPM) and do half a degree in accuracy?

> put a brake on it
Would it work? Are there light hobbyist electrically-actuated brakes that are fast? Would start by looking at electrical scooter disk brakes.

> Other?

Living without plumbing
noplumbing
Im considering renting my house and live in the backyard. Its a rural location and I got several abandoned brickbuilt structures that once housed cows. My idea is to convert those into a simple dwelling for myself. The building itself would be the easy part and for electricity I dont see it being hard to redirect it from the main house
Now plumbing though, thats the one area Im not comfortable DIYing so was hoping to circumvent it
I do have an easily accessible outdoor faucet/hose so my plan would be to meet my water needs that way

Main household functions where plumbing comes into play:

>washing machine
portable washers are common so no big deal, just fill it and drain the grey water
>kitchen sink
clean water jug, grey water jug. drinking water would be run separately through a gravity filter
>toilet
composting toilet. taking care of the compost piles might be a bit laborious but I dont see a way around it
>shower
feels like the biggest challenge and where I could use suggestions. theres many different portable shower systems for camping and such so its hard deciding which route to go. cold showers are a big no; a sad little sprinkle from a couple gallons wont cut it; any sort of electric heating is likely too energy intensive...
I plan on using a propane stove for cooking so Im guessing the shower setup to somehow involve boiling water in the stove? Im really not sure what the most efficient/comfortable system is. While the other amenities only require periodic chores, seems like prepping a shower would turn into a big ordeal every single time. Any ideas?

Feels like just by having access to on-grid water instead of relying on off-grid systems like rain catchment I already won half the battle but maybe Im just oblivious to all the challenges these things still entail. Am I completely deluded or what?

Home Security System needed
multi-camera-security-system
Need anons to point me to what I need for a camera security system.

Have a house in another city 30 minutes drive away that I'm renovating and am tired of feeling helpless every time I go there and see the house has been vandalized or there's been attempts to break in (area is 85% + white BTW)

I have electricity at the house obviously, but no internet.
Cheapest internet I can find is $40 a month with contract, which seems like a waste just to run 2 cameras.
OTOH, if I have just a DVR 2 camera system, and someone does get in, they could just steal the DVR.

Any anons have any recommendations?

Renogy Charge Controller Issue
46AB45D3-BCA6-4B71-AF0C-206F0DAD0413
I have a Renogy 50w flexible solar panel, Renogy Voyager 20w Charge Controller and 40' of 10g cable.

The system will work fine for ten minutes then will display :
PV (Panel Output?) : 22.8 V
PV: .1 A (or 0.0)
BT (Battery Voltage) :15-16v

The items on my system do not like 16v and I have had problems with them and the battery does not seem to be charging. I have tried two of the same controller but they both have the same problem.

When the system is working well for the first 10 min it displays

PV: 14v
PV: 1.2a
Batt: 13.3 V
Give or take those numbers.

Am I doing something retarded here?!
Oh the battery is a Renogy Li too...

Anodizing Aluminum
Anodizing
I've been trying for a while to learn how to properly anodize aluminum parts, but my results have been very inconsistent. No matter how gently I apply current, or what concentration of electrolyte I use, it seems totally random whether each job comes out looking beautiful or ends up an absolute mess. The failed jobs usually end up covered in some kind of white or grey plaque that I can only assume is some ungodly mix of oxides, hydroxides, and electrolysis products.

I suspect the problem is due to tiny gas bubbles that form on the aluminum. These cover most of the surface, reducing the effective surface area and driving up the current density to damagingly-high levels. A simple solution seems to be to agitate the mixture to shake the bubbles off, but so far this hasn't quite worked. Every electric stirrer that I've tried just isn't forceful enough to keep the bubbles from sticking.

Does anyone here have experience with anodizing? What kind of setup do you use? How do you get around the issue of gas bubbles?

I did my first casting today, I'm totally a foundryman now. My first two melts earlier in the week I made some ingots, just melting soda cans. >>2783890
Yesterday I made my first flask from a spare fencepost, and some greensand from sifted playsand and a mix of sodium bentonite and calcium bentonite. Yard marking calcium carbonate as parting powder, worked great. Designed a little ashtray in Fusion360 and turned it into a pattern. I did a pretty bad job but I was impatient and really wanted everything ready to do this casting today. Rammed up fine, might've been a little dry, but just barely. Worked out okay though, very happy with the result after a brief cleanup.

Do you scrap? Stack? Do you sell signs on Etsy? Do you sand cast? Investment casting? Do you like huffing zinc fumes and snorting silica powder? Show me your furnace, show me your castings.

Sand and jpeg compression don't get along.

The relay had something that looks like burns. I changed it, but it did not help.

Sanding down aluminum shavings

Most holes came out fine, but 30% still have metal shavings stuck to them, as well as generally rough edges.
I've already been sanding down the pot for 40 minutes with sandpaper but i feel like there might be a better solution. Anyone got any ideas?

Also how hazardous is aluminum anyway? I think any loose particles will just sink to the bottom of the beer, but i might end up drinking some too :/

Party-Tent
So I'm building a racecar in my dad's garage and he wants to kick my car out since he wants to start a project car himself.
Now since renting a shop would costs thousands of euro's per month, I was thinking to put it in the backyard but since it's a half naked chassis it needs to be protected from the rain.

My idea so far was to buy a ''party tent'' and reinforce the shit out of it with para-cord (illustrated in red) and put some para-cord on the sides that go deep in the ground with tent stakes.
If anyone has a better idea let me know.

And no, brick building is not allowed, just like wood poles in the ground, I can only legally put up a ''movable structure'' so nothing in the ground accept for tent stakes.
Thanks.

Best way to smoke loose crumbley tobacco?
pipe
I like to smoke loose tobacco. When I get to the bottom of the container there's a bunch that isn't good to roll from (too crumbly).

I've been using a regular weed pipe but it gets so clogged so often. I clean it with isopropyl alcohol but that barely works and is costly to soak it several times a week.

I also have a wooden pipe but that works even worse.

What kind of smoking device do you recommend?

Trying to grow taller, How do I make the seat go higher?
20240601_145053
I am 5"11 but I'm trying to grow taller using this cycling machine by progressively extending the seat but I'm already tall enough for the highest setting. Now I could just use pillows but that's very inconvenient and I have to clean the pillows too often because my anal shit sweat seeps into it. Like are there any other ways or maybe cushions I can use to emulate a higher raised seat without having yo rely on pillows I have to clean?

unidentified metal
IMG_3274
Hello, I have a sample of metal that I can’t identify.
I’m thinking it’s some alloy or something, since it doesn’t match bismuth or other metals.

It is very brittle and non-ductile, files and sandpaper easily expose its shiny surface under the orangish yellow sheen on the surface so it isn’t tough.

It is not ferromagnetic or responsive to magnets.

On the fragments with the exposed interior, it makes sharp edges and has a dull lustre

Can anyone identify this metal?

Loud speaker to bother neighbor through wall
Untitled
I have an asshole neighbor who won't do anything about his dog barking non stop. This is Argentina, there are no laws. I tried talking to him, but he doesn't do anything. I need to kill fire with fire.

We have adjacent walls, brick and mortar. See picture for rough sketch of what I think his house looks like.

My idea was to diy a powerful speaker and screw it into the wall, but I'm kind of a retard knowing how sound works.

Also I'm poor so powerful bluetooth speaker are too expensive. I was thinking buying a driver, an amp, and play music through audio jack with a phone or something. I can solder. Put everything in a wooden plank, and screw it into the wall.

How much amp does the driver need to be to travel through his house? Do I need a wooden box to house everything? I don't care about sound quality whatsoever, I just want to bother him. Or even better, because his dogs sleeps inside, play music every few minutes at night to trigger his dog to bark inside. The more power, the more bass, the better.

I eat once or twice a day, so very little money to spend. As cheap as possible please.

I know this uk fag made this, could this work? https://www.youtube.com/watch?v=N3k9lWz48rw

shed
Is this a dumb idea for a shed?

I have a little under 40' of stainless pipe and I want to build a 8x12 shed. I figure if I do it this way, I don't have to use rebar. I'd pour around the pipe first, let that set, and then inside the pipe. Would I have to worry about these posts sinking? I live in a region with a high clay content, so I don't want to dig too wide of holes either.

Is there any device that offers protection from single leg disconnects on a split phase 240v main?
Basically if one wire disconnects or stops providing power, the other wire is mechanically disconnected as well.
I am combining two ordinary wall sockets to make 240v 16a to charge my ev, it works fine as is, but it poses a hazard as one end of the cord can just be live voltage if unplugged.

I understand the risk and handle it accordingly, but it's at my workplace and I'm afraid it may come under scrutiny at some point.
I installed locking plug covers to render it safe in most cases but that's not enough.

I've been told not to modify the building wiring.

should I buy a Dremel?
lightbox-diagram
Hi /diy/, I have no skills in diy but I'm looking to get started with a simple project.

I have some decorative glassware and I want to display it inside a display box for safety and to keep the dust off, as well as to highlight the glass. None of the off-the-shelf options are the right height/materials so I figured I could make my own.

I am thinking of getting a piece of wood with the right footprint and routing in two channels, one for an LED strip and one to slot in an acrylic box I will also make to fit the channels. Then I can simply drill a hole and pass a power cable through the hole to power the LEDs.

My main issue is this: I have no power tools or a real workbench or anything. I have some basic hand tools but the only way I'd be able to do this by hand with what I've got is to carve the channels with a file or rasp which I really don't want to do.

I've heard people talk a lot about Dremels and I know they have lots of different attachments. Is the brand/attachments still worth buying? Will I be able to buy routing/sanding/planing bits easily enough? I have a handful of other projects I could use it for so I can see myself getting use out of it, but I'm open to buying other stuff if it's not too expensive and the brand has gone to the dogs.

Apologies in advance for the crude diagram.

Power stations, how do they work?

Had a good thread a couple of days ago where I was planning on using heat press, laptop and a printer outdoors.

It started with looking for generator for this task, ended talking about benefits of solar power. This pic related should technically be a good substitution for generator with gasoline charging.

But the power station is quite cheap, like 100 euros, wtfff. What's the catch, sounds too good to be true?

I repeat, it would be used to power a 1250 watts heat press, laptop and a printer. But will it be able to do that in reality?

DIY radar proximity sensor
fig018
I'd like to make a DIY radar-based proximity sensor for my robots. PIR or sonar would be easier but radar is cool. The VT radio proximity fuse from WW2 seems like a good design to copy. It produces a binary output ("all clear"/"something is close"), but I bet I can turn that into a useful nearest-object range value with a microcontroller and ADC. They had to use vacuum tubes in 1942 but now it's 2024, so I bet I can drop in a 2N2222 transistor and get the same results. From my Googling and the VT fuze manual, it seems like they used a frequency in the 150 Mhz range, in the upper range of switching speed but achievable with typical ubiquitous BJT/2N2222 transistors.

Has anyone tried something similar before? I couldn't find many examples of breadboard-scale radar circuits online. Will post updates as I go. Thanks in advance.

I've got a 1950s detached garage I'd like to turn into a shop. Problem is it has zero insulation and it gets hot as fuck in there. The construction, from the inside out, is stick framing, tar paper (also called roofing felt), and wood siding.

I know using fiberglass or cellulose blown-in insulation could be a huge no-no if there's a leak. What about rockwool or ridged foam board insulation?

>Where's the sheathing?
It was constructed on the cheap and before plywood was common. It uses let in bracing for stiffness and has no sheathing.

>Weather
California central valley. Hot summers, mild winters. It never snows here. We only get a few nights a year where it drops below freezing. It rains in the cooler months but not that much. It rarely gets humid.

The last part I'm sure about is actually a right step.

I'd rather be set in stone and know what to do before I do it because I don't have a space where I can fail at the moment.
