Is using laptop panels as external screens practical or just a novelty?
I got a stack of 14" panels and it'd be neat to make a 3 panel low bezel display.

>practical
not really, it is a dick to set up, but once it is set up it shouldn't have any problem running like normal screens, so the problem is do u want the hassle to go through getting the parts and making them work and potentially a fuck up somewhere will make everything not work.

>or just a novelty
yes
>>
>>1121134
Wouldn't call it pure novelty

There is a point with recycling broken laptops like this to save money and on the other side you can do mods like wacom tablet + such a screen for a ghetto cintiq wich would cost otherwise 1000+ bucks.
>>
>>1121133
not very practical as you have to build everything around but if thats no problem and you have them already laying around and willing to spend some money on controller, then its no hassle in my experience

you just have to be careful getting the right controller but the chink seller on ebay are pretty helpful, they will need a serial and pick the right themself

if you want to run all three together maybe try fitting you power source for multiple controller

I was born or perhaps through posture and nutrition developed pronated feet and knocked knees. I routinely strech the adductor complex and activate the posterior chain daily but its congenital bone mal formation and i crush my boots an the lateral portion is there any home crafted insert I could make? Perhaps made of wood since my pronation is that tough.

Go to a doctor man... diying repairs to ur own body can fuck yourself up even worse. If you dont have the money, save up and wait until u do instead of trying to do it yourself. Better for a doctor with more than 20 years of experience to be held accountable than some anonymous podunk on an internet messageboard

I've just had an idea.
So it seems, you take a xenon flasher, and put HV or whatever though it, and it makes a spastic arc across it.
Pic related.

The thing is, how hard is it to make a xenon tube? It seems just a tube, filled with xenon, and a tungsten anode/cathode.
I would assume the simple arc doesn't make much heat, so glass and tungsten are a bit overkill.

Regardless, here's my idea.
Led Whip aerials are all the thing for offroading. But what if I made a fucking 6 foot plasma tube whip using the idea of a clear semi-flexible plastic tube?

Anyone know a lot about xenon lamps? I can't seem to find anything about what pressure they are or how to get different colors.

Here's a pic of a normal led antenna.

glass is use because you need to draw a near vaccuum; anything flexible enough to bend will simply flatten under the difference in air-presure, raising the internal pressure.
>>
>>1120814
>so glass and tungsten are a bit overkill.
Plasma is pretty corrosive. Glass is used also because it is air-tight and won't outgas much, unlike some random plastic hose.

>I can't seem to find anything about what pressure they are
Around 1/10 atm.
>how to get different colors
Current density has an effect and normal neon tubes just use different gases, gas mixtures and fluorescent coatings to get the desired color.

I added yeast to my apple, orange and pineapple wine. It's been 3 days and no bubbles I'm starting to think I may have killed the yeast or something. I put it in hot water by mistake because he said to soak the yeast on the package.

What's the maximum time it would take for bubbles to come up through the airlock?

When should I get some new yeast if I think the yeast I added died?

I have a tear in my (fake) leather chair.

How do I fix it, /diy/? It looks kinda like this. Even though I have another chair in the garage, I like this one a lot more but it has a fucking tear in it from years of use. I bought some fake leather that looks just like the fake leather on the chair and would just like to glue on a patch.

What kind of glue do I need? I don't care how hacky it looks.. .I just want it to stop falling apart.

Thanks for any guidance!

There are some stuff sold in stores to repair leather/pleather. But that stuff has its limits. What you have there is probably more worn than it looks. You can try glue.. probably won't look too good though. I'd use contact cement. Just be damn careful since when it sticks it's stuck forever... forever......... F O R E V E R

Insulation question..

Since spring last year I moved to the top floor of a 20 story apartment building. It's an old building with crappy insulation and an 50 y/o heating system. This winter is though as temperatures in my living room are about 60-65F (16-17C). Anywhere in my house else it get's about 50F (10C).

I've always learned that the top floor in the winter is hot because of heat rising up. So I'm considering adding additional insulation to the roof.

Will this work sufficiently to make it a bit warmer in my house? Anyone here living on the top level in an high rise as well? What are your experiences in the winter? Is it hot or cold?

Nigger rig it with styrofoam plates.
Cheap as fuck but also a fire hazard, so beware.
>>
>>1120752
Since you can't open the ceiling and add insolation up there, you can't exactly hang it all that well.
Tips I do have. Bleed your radiators and bitch to your landload every. Single. Day. That it is cold because they'll fix it just to shut you up; worked for me
Second is to make sure your window close tight and you could put the clear plastic on them to insulate since you lose a lot of heat to windows.
Third, run an extention cord from a public (building) socket to under your door to power an electric heater.
If you have a gas oven which you don't pay for gas, when you get home turn the oven on for 3-4 hours the. Leave the door open when your done. Since you're not leaving it on 24 hours you're not going to sufficate yourself
Also, electric blanket works wonders at night, that's what I do as well
>>
>>1120752
You should buy an ir thermometer and measure all walls and ceiling. This will tell you where to add insulation first. Insulate your ceiling the way they insulate house roofs - make a construction covered with drywall with mineral wool inside. Pick the coldest wall and do the same. Or do it with all of them if you have the money for materials. Do not forget water vapout isolation to prevent mold.

Also, if you pay any kind of renovation costs then go to administration meetings and push to have the building insulated from outside.

Kinda hard to tell what I'm looking at, but from what I'm gathering it looks a little overboard. As long as your supports are evenly spaced throughout the extra horizontal parts are unnecessary. Also are you only working with 2x4?

It must be a very new product. I'd assume very specialized manufacturing. I just had my kitchen redone and didn't hear about this anywhere. I doubt you could do it seamless. That is also probably digitally touched up and doesn't show it 5 years later in a kitchen. My research for diy counters advice is butcher block followed by granite, followed by huge tiles mimicking a stone surface with very little grout and lastly Formica. Anything but off the shelf Formica is just to close cost wise to something much better. I have seen a few very good tiled countertops that seemed really nice for how much they save. Especially since 24 inch tiles now are pretty common. That's basically the same depth as a countertop. Just make sure the pattern isn't flowy so you don't have huge differences. Quartz countertops are the shit. I have Cambria in my bathroom and some German stuff in my kitchen. They tend to cost about 50 a foot though installed by someone else and normally a sink included. If you do a higher end tile plus backing it's maybe 10 to 15 a foot if you do it yourself.

>>1120383

Nope. Postform counters are limited in what you can do with them, and trying to mod them with a heat gun will (guaranteed) fuck them up big time...

Since the water meter is in the way, i'd like to make use of the rest of the void useless pspace left by. I have a twin bed, so i'd like to make a bed extension of sorts from the corner to the frame of the water meter.(ik it looks like shit , but it works for rn.) So i'm making a frame rn, i'm wondering how would i best layer material on top basically match the feel of a matress? Is the only way a matress section cut out for that size? Will be posting pics of updates to come, im open to opinionms on what i should do with the space. I was thinking i'll have a shelf 2-3 feet over, it'll make some shelf space + nice and cozy to be under something, maybe add lights and other features.

Out of curiosity, how much does fixing weak floors cost?
11 posts and 1 images submitted.
>>
>>1120187
if its just the floor and you are handy with a drill then price up 3/4 to 1 inch ply.
if its the joists underneath then considerably more.
of course if its rot or infested its even worse.
>>
>>1120187

Go take a look at it. Like >>1120188 said, you can do it yourself if it's just the subfloor. If it's the joists, then you're screwed. If it's water damage, you likely have mold issues and problems with the plumbing or roof.

If you have the money and its a bank property, give them half of what they're asking and they'll take it.

You should really go look at it though. Get a pair of shitty clothes on and climb under the house to see what the damage is from. If you can dig a screwdriver into the joists at all, then they're rotten. New joists are a pain in the ass to put in if you can't sister another to it.
>>
>>1120188
This pretty much.

Usually a weak floor is due to water damage.

You really need to take a look at it. If the joists are fine and it is just a bad or rotted sub floor, it's a matter of tearing the floor out and putting down a new sub floor. 23/32 T&G is $23 a sheet here. Glue and screw. Then install a new flooring over it.

Bad joists are usually more work. Sometime you get lucky and the layout allows for you to just sister the existing joists with new ones.

It could also be failing supports. Previous owners could have removed a load bearing wall or support column in the basement. These are harder yet to fix.

It could even be something like massive settling or improper foundation. These are insanely expensive to fix.

You will want a competent contractor to look at it and likely a structural engineer.

Minor updated on that, switched the refresh rate to 50 and changed the resolution and it's still flickering though only on whiter pages like most blue board backgrounds and it's slightly more stable. Like i have a fucking vaporwave monitor.

Electricfags and radiofags,

I have some experience with electronics and radios, and was thinking about the possibility of a portable CB radio. I know they make handheld ones, but I happen to have a spare CB radio for car mounting that I would like to use.

Would it work if I hooked it up to a car battery? Would it be practical? Would it work? Would the battery last long enough (and if it died, would it be feasable to just charge it with jumper cables?)

I do a lot of offroading and camping and some of my friends don't have CB's, so I'd like to give them a way to communicate with the rest of us, as well as be able to communicate while dismounted.

Wow anon, you actually sound legit.

The answer to your question is yes, you can hook it up like that. The other thing is that you don't need a whole car battery. A smaller battery will still last a long time.

Here's what you do. Go get 2 lantern batteries (6V with the springs on top). Hook the positive from one battery to the negative of the other. Now, with the two springs left over, hook the + up to the CB + terminal. Hook the - up to the - terminal on the CB. Done!

When you hook the batteries up like that, two 6V lantern batteries become one 12V battery, just like in your car. Those lantern batteries will last a long time too. Probably several days of the radio being on. Godspeed anon!
>>
>>1119950
Thank you for the constructive reply! I wasn't expecting that at all.

If I wire two lantern batteries in sequence (?) Like that, is there a certain gauge wire I should use?

And are they rechargeable? If so, how would I go about doing that?

I really like that idea. I think lantern batteries are a lot less expensive than a car battery, too. Again, thank you!
>>
That pic looks more like a motorcycle battery, which would be easier to carry than a car battery. I think they are also 12V.
