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.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

Was considering buying a solar panel to put on the roof of the house. To reduce energy bill a bit.

But after a quick check I see that: 100W panel costs hundred dollars, And I will need to buy a battery and an DC to AC convertor. plus various other stuff to install it. And assume cost will be at 300$. How long would it last me? 5 years? Since there I see no easy way to integrate it into your power lines it will not be used 100% percent.

It seems it is not even worth it.

Do any of you have one at home? What are your opinions and costs considerations after long time of use?

Big project. if I wanted to make a machine that makes a pizza from scratch using an arduino to sequence it, where on earth would I start?

I would probably need
>a conveyor belt of some sort
>a dough mixing machine
>a press to flatten the dough
>an extruder for sauce
>dispensers for toppings
>a built in way to refrigerate the raw materials
>an oven
>a touch screen for ordering and an arduino to operate/coordinate the sequence

pic related machine already exists but my thought is rather than having it like a vending machine to run it like a kiosk or small walk-in restaurant. i obviously wouldnt be able to just buy one of these machines and reverse engineer it for a shop because of patent laws, but its also not economically rational to try and assemble each piece myself.

does anyone here have any experience with simple automated production lines? I really am not sure where to go, but I am willing to do a shitton of research and educate myself. Im in a bachelor of science right now but it'll be a while before I can do this *just* with my schooling education, and Id like to try this as a project to subsidize my living while Im in school. also, I understand it might take a lot of startup capital, i have access to some amount of capital so Im not completely SOL.

for a job as simple as a pizza machine you don't need any programmable logic unless it's a coin slot mechanism in which case it may simplify things.
>>
I would have a flour Hopper feeding into a spiral mixing chamber with CO2 injected water to avoid the need for yeast and rising time. as the mixed dough exits a flat extruder nozzle onto a wire conveyor belt it passes has a continual strip underneath a spray nozzle for tomato puree and a shaker Hopper for industrial mix pizza cheese blend, if it's only one standard kind of pizza the Hopper can hold a pre blended mix of grated cheese ham mushrooms sweet corn etc or you will have to have separate shaker hoppers controlled by front panel switches.
>>
this trip will then pass through an oven that uses radiative heat from electric elements above and below the wire conveyor as close as possible to pizza strip for efficiency. a reciprocating cutter blade then chops portions of pizza before they slide through the exit chute. this system requires minimal moving parts and zero electronic logic. if it is required to have the machine running in stop start mode all the motors can be shut down together leaving only the chilled ingredients cooler in operation which can be further simplified by attaching peltier chips to the sides of aluminium topping hoppers. such a machine would be quite easy to make with few skills and basic hardware store equipment and should be fairly reliable as long as the conveyor path cannot be blocked. simple thermal cut outs should be in place for safety

How would be the safest procedure to clean this mess?
I'm going to soak it in vinegar, and the use a scotch brite pad. Would that damage the enamel?

Not at all. I've used it on my tub & surround at least 5 times and there's no scratching what so ever. The plastic brushes aren't hard enough to scratch a ceramic tile surface. You just have to make sure you get the softer ones designated for bathroom cleaning.

The pump idea is clever but I think it's a lot simpler to just soak some paper towels and slap them on all the surfaces, and come back occasionally and spray them down.

Hey /diy( I just got my first motorcycle and needed to change some parts on it like front brake lever and some side fairings, nothing major. I got some tools like basic wrenches, screw driver set, a standard and an adjustable plier, but thats basically all. Now that I'm going to be really playing with this baby (honda dominator nx '89) I want to invest in some tools for the future.

What tools do you guys who are experienced with motorcycles and generally just automobile repair recommend I buy?
2 replies omitted. Click here to view.

Been using the same sears craftsman set I got 10 years go. And whatever inexpensive tools I needed, as I needed them. I didn't buy the cheapest chink crap, but I didn't buy the most expensive stuff (jet, snap-on) either because it isn't necessary for low use.

Anyway, get the climer or haynes manual for your bike. Tells you all the tools you need for whatever job.
For some reason, people have religious wars over how to lube chains. I use a pro-oiler and MC motor oil and it works great.
Microfiber towels for cleaning and drying.
>>
>>1408113
Buy tools as you need them, not because you think you'll need them. If you don't know what tool you need for the job then you don't know how to do the job. Most motorcycles come with a "tool kit", but for an older bike you'd be lucky to find one specific to it. Do some research and you can easily put together your own kit.
>>
>>1408132
>Bike lift. you'll ruin your back bending over or siting on a stool
Nice to have, but not super important.
Chassis stuff is easy enough to get to, anything in the engine more than an oil change or something quick under the stator or clutch covers, it's worth getting the engine on the bench. There's like 4 bolts for my bike for that; still less than 20 when you factor in everything you have to pull from ride-ready to motor-on-the-bench.

>>1408132
>battery impact tools like Milwaukee
this
Another tool I waited way too long to buy is a cordless ratchet driver. If you go with the Mke M18 stuff, the M18 charger has an M12 hole on it. Get the M12 ratchet driver, battery or two, and use the same charger.

>>1408138
>sears craftsman set
Same. Though I do recommend keeping a "complete" garage set, and picking up an additional kit to keep on the bike. I work out of my bike kit most of the time, rather find out there's a tool/bit/etc that I need when i'm in the garage rather than when i'm out on the trail.

Air compressor, if you don't have one. 10-12gal is "good enough" but bigger is always better. You can add volume with a harbor freight air tank, buy some couplers/fittings from McMaster and build your own valve/connection assembly, the one it comes with is real janky.

Will admit I use this more with the truck and sled than the moto. Still handy for the tight bolts that are difficult to get to with an impact.

>add volume with a harbor freight air tank, buy some couplers/fittings from McMaster and build your own valve/connection assembly

this little fucker's real handy for airing up truck/trailer tires, running an impact on the truck, or other small jobs where I need a little bit of air.
Been using it a lot lately to drive an air nailer in the house. Let the noisy air comp fill in the garage, and take the smaller tank in with me.

Hose adapter lets me run this tank in parallel with the compressor for more capacity.

DISCUSS CUTTING TOOLS AND TECH HERE GUYS.

and because everything has an agenda heres what I want to talk about.
I am thinking go buying one of these fancy compound saws. I like the regular miter saw I inherited(an old Delta), but the motor died.

I'm looking around at all the fancy new stuff out there and I figure you guys would have some experience about these things. what brand name, would you recommend if the biggest thing I expect to ever cut is a 4x4 but usually just 1 or 2 by 8s for regular projects. by 10s at irregular intervals.

Hey DIY I was not sure which board to put this in because /mu/ acted like a bunch of assholes and /g/ wanted nothing to do with hardware so...

I got myself a small whisper room for voice over work, and while it helps to get rid of outside noise there is still a decent deal of reflection inside the booth that I can hear back in my mic, what is the best way to treat a small room like this?

Some say to avoid acoustic pyramid foam like the plague and go for some insulation like ownens corning or something like that

Others say that while insulation can help deaden the booth it won't help with reflection so foam is better than it by a mile

And others tell me to just make some frames full of towels and put them in the booth and it will make it all just as well...

I am not good with the physical studio side of engineering sound I can just work on my own files so I know what sounds good and what doesn't but I wanted to hear what might be the best way to acoustically treat my whisper room before I start.

Any help and advice is much appreciated

>>1407806
To be fair he did say op doesn't have to approach this autistically and it's pretty true. Thing is, op is building a small voice over booth and needs it dampened for voice. This is a simple task and can be don't with household items, nearly any adv from 4 chan is going to work and he's probably already figured it out himself abyway. If op was building a 80m2 control room within a room in a concrete square room then, figuring out which modes are present in the room and choosing the correct bass traps and acoustic foam type depending on the instrument being recorded and if the room is changeable to accommodate recording vocals and drums in the same space, well 4chan probably isn't the best place for that.

Curtains, rugs, carpet, coats, foam, towels will all work.
>>
>>1407746

It is correct that in a space as small as yours you will get zero benefit from sound reflection foam and the like.

Doing something like this is perfect and cheap https://www.youtube.com/watch?v=pABvTWSxOes
>>
that seems way smaller than one would want to be using for something like voice over work because if the area is too small just barely a couple feet then you are going to get major reflections in your recordings no matter what you do

I am currently remodeling my bathroom because my dog peeled up the vinyl and chewed up the subfloor. My bathroom is pretty small, about 5x5 not including the shower stall, and before it had a single piece of vinyl covering the whole floor.

This time I think I will try using peel and stick vinyl tiles. I am wondering if a sealer is used between the tiles to prevent water from leaking between the seams. In a video I watched the installed just peeled the tiles, butted them against each other, and stuck them to the floor. What prevents water from sapping between the tiles?

FUCK. THAT.

Those are shit. Especially in a bathroom where the floor would get wet somewhat regularly.
>just peeled the tiles, butted them against each other, and stuck them to the floor.
And that's how they're supposed to go on. No grout, no sealant, no protection whatsoever.
They're fucking shit, don't do it if you plan on living in the place for more than another month.

Is the problem wtih the underlayment, or the subfloor itself? Subfloor is going to be a bit more complicated/expensive to repair, and will likely involve sole plate replacements as well.
If it's just the underlayment, scrape that up.

Personally, i'd do real tile. If you're living there for a while, the extra money for an in-floor heating circuit might be a good investment.
Cement board underlayment, bag of mortar, box or three of tiles and a box of grout, knock it all out in a week.

I'm in New York City/Upstate, you can't get any more LAWYER-Y/SUE-Y than New York. Landlord can not "just stroll" into your apartment. Landlord must give minimum 24 hours (written) notice to enter a dwelling, and no, the tenant does not have to "agree." If the landlord give the notice, and tenant says, no, the tenant can suck a dick. The only time a landlord can enter a dwelling without prior notice is in an emergency situation, including but not limited to a plumbing leak. Now, this being a house that OP is renting, if the landlord is paying for things like, the water, heating (fuel oil,) etc, perhaps there are instances that landlord may want to maintain the equipment. I don't know OP's lease/rental agreement so can't speak on his case. But he sounds like a lunatic.

t. 20-unit landlord. Has been sued. Including "he came into MY apartment" and won every-fucking-time. Tenants are scum.

>>1408185
WRONG! A lease/rental agreement may state arrangements that are in direct opposition to the norms to a particular State's Rental Laws, if both parties agree to it, in the signed lease/rental agreement. However, if such clause is deemed "unconscionable" by the judge, then it would be thrown out. Depending on the State, but most States this is allowed.
