Can my /diy/ bro's help me out? Im making a cat tree just like pic related. Ive got pretty much everything I need but im having trouble figuring out how they attatched the curved peices (circled in red) to the posts. Any ideas?

on the ones I've thrown out, they were just made of wood beams (the square uprights) and all the rest was paperboard tube. They were mainly held together by long staples and hot glue.
Also--in my experience it's easier to just buy a new one every year and toss the old one out.
The cat(s) won't sit on it anymore if it has their fur matted well into it, and you can try to vacuum it regularly but after a while you can't get the matted fur out.
Because of how they're built (staples and hot glue) there's no easy way to dissemble them non-destructively to cover them with new carpet.
They're good to have because cats instinctively like to climb... If they have one or two tall things they're ALLOWED to climb, they will usually stay off everything else (like the drapes).
It's just part of the budget of owning a pet.
Dogs tear stuff up (no way around that) and cats need a cat tower (to keep them from tearing other things up,,,).
Keeping pets costs money.

The staples weren't normal staple-gun staples--the width of the staples was maybe a half-inch, but the legs of the staples were really long--like 1.5 inches.
They just drive a few staples in at an angle to hold the thing, and then hot-glue it.
I want to sleep inverted facing downward/diagonally.
How can I do this? do you need tools or can I set this up easily? give me ideas. Thank you.
And it CANNOT rest on my face, I have to be like in the pic: face elevated off the ground, facing downwards as steep as possible with comfort.

I've got a 5v (2A) power source, different electronics hooked up, and if i plug my phone into it as well, one of the things shuts off. What is happening?
>>1028091

What are you doing?
Ill post a kindof diagram of the setup. Basically i've got a subwoofer with a 5v phone charger which i put in it. Stay with me, diagram in 10 mins tops

So i found a bunch of vacuum tubes in a tv repair box from my granddad. Today i'm bored and was wondering you you guys had any projects that use them. I will put the spesifics of the tubes i have if you guys want
i dont have the ones in pic i was too lazy to take a pic of them

I too am interested. I got a few hundred myself.

Hipster tube amp. Amplifies hipsterism.
Use them for lighting a room. You'll probably need to cover the entire ceiling in them to get any usable light and it will be the most inefficient thing ever.
Can you help me, /diy/? I want to make a cool t-shirt or hat for one of the Pokémon Go teams for a convention in a few weeks but I don't know how to get the logo onto clothing without it looking like shit.
My apologies if this should have been asked in /cgl/...

Is it?
>>1027950
These guys have treated me right in the past. I doubt you will be able to get better prints without dumping a crap load of time and money in to it.
Sorry to say on /diy/ that your best option is to buy, but if you really want to kill some time or are planning on making a ton of these then will post some silk screen tips.

I want to repair a rotation evaporator glastube. The nut where you can attach a tube is broken. It is made of boro 3.3 glas. Anyone can tell me how I have to proceed without destroying ist? These are pretty expensive. Wenn fooling around with other glas parts they broke upon heating them
>>1027930
While waiting actual glassblowers...
1. Posting a pic of the actual broken part would serve you better than some random pic.
2. You could list your tools, since it's pretty likely that you are lacking something important (and expensive).
3. In addition to trying to fix it by yourself and buying a new thing, there's the option of paying a professional to fix it.
>>1027930
you need to warm the tube, to bring it up to temperature, so then you can cut it with a torch. post pictures..
I am a beginner lampworker, I can help alittle

I'm looking for some open-source or free electronic/electrical simulation and design software, but one that is more geared towards larger stuff, like an electrical circuit for an automobile, rather than PCB and IC design, which is what a lot of them seem to be geared towards. Any Suggestions?

I've always wanted to build a model city or town, but have never gotten around to it. I don't want kits, I want to do it completely myself, building a small town.
Right now, I have a garage to make one in and a big table, but no tools or supplies.
What do I need to purchase for this, how much will it cost, and where can I find out how to put it together? I'm surprised this type of thing doesn't have a general here or on /toy/.
Thank you very much, /diy/.
>>1027828
/toy might be able to help, model railway guys tend to love that shit
>>1027830
It doesn't seem like they have a train general.

Is close, so I'll ask there, too. I hope to get answers from both here and there, though.

Sorry, I'm an idiot.
I have dogs (long and short haired), they shed hair everywhere. My current vacuum costs me $30 a year in bags and thats with me reusing the bags at least 3 times each. I'm tired of bags. I tried a Shark Navigator but the canister was so small I was constantly emptying it. It also took a long time to clean the house because it is so small. I don't care that about filtration, just dog hair.
Does anything know of a bagless vacuum that can handle pet hair and it is not made for apartment dwellers with only 25 square feet of floor?
What about shop vacs? Anyone use them inside their house? Can they get dog hair out of thick carpet?
>$30 a year
>$2.50 a month
>literally cheaper than feeding a starving African child for just .50c a day
Get an undercoat brush and brush then regularly. Or get them groomed regularly. Or just pay the 30 fucking dollars a year.
>Shopvac won't work because it doesn't have bristles to pick up the hair out of the carpet
>>1027567
I recycle the bags. If I didn't reuse them the cost would be closer to $90 a year. The first few years I had it thats what I did but I did the math on it and it was stupid. So, all in all, the vacuum has cost me close to $400 in bags over its life. Its an $80 vacuum. If I had spent $300 on decent bagless I would be ahead by now and wouldn't have to go through the hassle of tearing open full vacuum bags to empty and reuse them.
>>1027581
Bosses cleanview 1331? I think. Best vacuum I've ever owned. Cleans our carpets so well, the first time we used it the canister was completely full on one bedroom alone because our old vacuum sucked (lol). All of the hair was gone. Pic related

Cheapest thing would be to add a GPU and better PSU to handle it. More ram to bump it up to 4+ GB would help but ddr2 is probably still overpriced.
I want to build a mini portable PC using a raspberry pi as its core. Ah, ive also never done something like this though... I have a soldering kit and a lot of tools but i havent yet decided on what to buy as parts for it.
I know i could get like, a notebook or soemething but i wanna build something, have something to spend my time on this summer and also, i dont have the money to get a notebook.
Any advice?What do u think? is it lame or somehting? lemme know
>>1027354
>i dont have the money to get a notebook.
You are going to be spending just as much to make a shitty laptop as you would to buy a good laptop

Any leatherworkers here?
I have an antique bag with leather parts. Some of the leather parts are very, very rigid, bordering on cracking in some places.
From what I can tell, it needs a good oiling since it probably hadn't received care for over 70 years now.
What would you guys recommend for 100% neatsfoot or mink oil?
I was thinking pic related for neatsfoot since it seems widely available, but I'm sure someone here has a better idea.
What's better anyways? Mink oil or neatsfoot oil?
Give it a once over with amyl and get high, then oil it up
>>1027353
Amyl nitrate, leather cleaning product that can give you a short high
How can I dye shit good?
I ride a motorcycle but I cannot go full space-elf motorcycle adventure $700 pants.
Occured to me the local thrift stores are induated with old acu army pants. They have a very abrasion resistant 50/50 nylon cotton ripstop and pockets in the knees that fit knee pads. That pattern is distinct and ugly. How can I dye these to make them less school-shootery?
Should I soak them in bleach to lighten the pattern?
I I live in an apartment and cannot use the washing machinea to dye shit.
I want them to be dark brown to look like normal people pants and to contrast with my black motorcycle gear.
Any suggestions?
>>1027234
You can buy clothes dye online.
Bleaching them first might just turn them pink but you should probably try it on one pair.
Sorry that's all I got. I've bleached jeans before, they turn white, but most clothes seem to turn pink.
>>1027239
I was thinking to bleach these uniform pants to scrub the ugly digital pattern away then dye them. so there is no camo print evident after it's dyed.
I'm wondering if it's OK to bleach than dye or will it ruin the fabric or cause the dye to turn to poison gas or something.

I've googled batteries again and again but can't find a clear cut answer that's less than 50 paragraphs without quoting the entire book of thermodynamics.
Can someone please explain to me, like I'm five years old, how to realistically make batteries work without advanced knowledge of circuitry and without using the phrase "it depends"? The most simple calculations that will get it working, not working with utmost efficiency, just..working.
Here are some extreme examples:
I have a single AAA battery and a 12v motor. How can I make the motor spin? What are the most simple basic ways that I can spend some time/money to make this happen? What are the side effects?
I have a 9v battery and a 5v USB drive. How can I get it to show me my porn? What are the most simple basic ways that I can spend some time/money to make this happen? What are the side effects?
I have a 12v car battery and a 48v wheelchair motor. How can I make the wheelchair go forwards? What are the most simple basic ways that I can spend some time/money to make this happen? What are the side effects?
I have a 10MW nuclear reactor and a single 3v LED. How can I make the LED light up? What are the most simple basic ways that I can spend some time/money to make this happen? What are the side effects?
I just want to know how to battery.
Thank you
>>1026991
"it depends" is literally the answer, every scenario you described is completely different. However, you don't need to understand a whole lot to be able to figure out what happens when. But since you don't want to put in even that much effort,
>12V motor with 1.2V battery
The motor will start spinning at around 3V, so if you connect 2 batteries in series, it will start spinning. For full speed, you need 10 batteries in series, or a step-up converter, you can buy the latter on eBay around $1-$2. Step up converter makes higher voltage out of lower voltage, but they usually have 3V minimum working voltage
>9v battery, 5V usb
Ebay, step down converter
>12V car battery and 48V wheelchair
Just get another 3 car batteries or a single 48V one, a step up converter would work in theory, but in practice it would cost a lot because it needs to handle a lot of power
>nuclear reactor
now you're not even talking about volts but watts
For most devices, the voltage rating is fixed, a 12V device should be given 12V, a 5V device 5V; some exceptions are motors and heating elements that are listed with optimal working voltage. A 12V motor will spin at 3-4V, but very slowly, and will spin at 16V very fast, but will overheat and may burn out. LEDs should always be powered around the given ~3V.
Ah means amper hour, so if you have a 12V 1Ah battery and a motor that uses 1A at 12V, it means the battery will last exactly one hour. Wattage is voltage*amps, so a 12W motor operating at 12V will last 1 hour on a 1Ah 12V battery, 30 minutes on a 1Ah 6V battery and 30 minutes on a 0.5Ah 12V battery. From Ah you calculate how long your battery will last.
Read those 50 paragraphs and learn basic electronics, if you're really dense, play around with circuit simulators
>>1026991
It would help if you could link to specific examples of something you want to do. In particular, try to find examples of things you want to run, that list their voltage and current requirements.
>... How can I make the LED light up?
The simplified explanation:
To run one off of a wall outlet: you'd (me, at least) want to use a transformer to drop the AC volts down to ~6 volts, and then four diodes (1N4007) to make a full-wave rectifier.
"Plain"-style LEDs always need a dropping resistor connected to them, and they need to be connected to DC power with the polarity correct. Not doing either can instantly burn them out for good.
Consult the Google for "LED calculate dropping resistor" for pages to help with that.
>>1026991
>I have a 10MW nuclear reactor and a single 3v LED. How can I make the LED light up? What are the most simple basic ways that I can spend some time/money to make this happen? What are the side effects?
nuclear power is not analogous to a battery. nuclear power, or wind/coal/solar/hydro all create AC power. that's a larger subject than I feel like explaining, but in short, not the same as a battery.
an led has a forward voltage because it is a light emitting DIODE. This is the minimum voltage needed to get it to draw enough current to light up. It is not a purely resistive load such as a 3v tungsten bulb, which will react more or less linearly to the voltage applied.
like it's been said, the examples you list cover an incredibly wide range of subjects and really don't lend themselves to eli5 explanations.

Oxy-fuel welding systems can cost upwards of $1500+ .
How much could be replaced with standard oxy-acetylene kit or built, for non-professional applications?
>>1026707
>2016
>torch welding
Why not just stick?
>>1026708
I am considering that too. Oxy-fuel systems are still good for cutting and for dropping intense, concentrated heat where you want it, though.
>>1026707
>Oxy-fuel welding systems can cost upwards of $1500+ .
They can also be bought for a couple of hundred dollars.
>>1026711
>Oxy-fuel systems are still good for cutting and for dropping intense, concentrated heat where you want it
Buy a standard hose, regulator, and torch set.
Rent oxygen bottle from supplier or buy in-date oxygen bottle and have it filled or refilled.
Buy propane cylinder for use as fuel.
Propane works great as a cutting fuel and is cheaper than acetylene.
Best results obtained if you change cutting tip to oxy/propane tip. (different diameter holes)
