Best way to insulate an air duct is just wrap it with foam or other types of insulation, but tobehonest just wrap it with cardboard with some duct tape will help a lot since it is not a huge issue anyway

What do with a cherry log that's 1m long and 20-30cm in diameter? Basicaly i need ideas. Google mostly gives me chairs and benches and i have no need for those. My tools are limited to chainsaw ( could be used to rip that bitch), el. plane,circular and jigsaw and a lot of hand tools. I guess i could have it planed somewhere nearby but i could go the hard route with a hand plane/scraper and a shitload of sanding. God i just love sanding. Don't you?

Another thing i forgot about and actually needed could be put in the stupid questions category. I wanted to get into woodburning for a while now since i'm good with art. I could get a woodburning pen but i have a soldering gun i got a long time ago for free. The problem is that the fucker is gun shaped so it's rather hard to draw with it. Could i make somethin that would allow me to grip it closer to the tip so i have more control. What material could i use that could resist the heat and be at least somewhat shaped so i can grip that gun where i shouldn't be gripping it?

I need some good quality seamless and perfectly straight stainless steel tubes, even better if they're polished, I would order them from the internet, but I'm afraid they can be easily bent during transport, even a fraction of a milliliter off shape could ruin it for me.
I've tried an aeromodelism store, but they only had aluminum and brass tubes.
I'm looking for an inner diameter of 4 to 5mm and a length of around 30 to 50 cm, the thicker the better.

Go to your university and ask at the Mechanical engineering labs, peharps they know or at least know someone who did a task/work/thesis using one of those. Heck they even may have it themselves.

so i built this oscillator to put in my amp to vary the bias on the output tubes for a tremolo effect. it works but it make a thumping sound when the depth/intensity is turned up really high. i looked at it on the o-scope and the top half of the waveform is kinda janky, like almost a triangle wave, whereas the bottom half is a beautiful sine wave. will putting a cap to ground from where the .1 cap meets the two 47k resistors smooth this out maybe and maybe get rid of the thump?

>>998357
Thanks, I'll try that, hopefully it won't be terribly expensive, I don't need precision down to the micron, just a straight tube, straight enough to evenly roll on a glass table, I'll ask my local hardware store first though.

>>998221
Not sure if this is wrong, but it sort of feels like it would be bad to insulate a soldering gun like that. Is the barrel supposed to be able to radiate heat?

>>998362
Depends on what you actually mean, but you could try:
- Increasing the 220k resistor on top of the depth pot or reducing the pot value. This directly reduces the maximum depth to (probably) non-thumping value.
- Increase the 470R resistor on LND150's source. This reduces the tremolo oscillator's output directly and quite likely makes the output more sine-like.

I'm assuming the thumping sound you noticed is because V3 gets overdriven, not because the tremolo waveform is shit. In principle you could also try changing the input tube or adjust its biasing.

Having moved from 240v land to 110v land, how can I rig up a 240v kettle to boil water?

By the time the fucking kettle boils, I've given up on the idea of having a cup of tea, it really does take an age longer

>I was wondering what's the best way to insulate it
One easy and cheap way to insulate it is to wrap it with some pieces of a space blanket (survival blanket). This is a thin piece of plastic that is coated with either aluminum or gold. The gold ones would reflect heat slightly better than the silver ones if you have a choice, but most places just have the silver ones and the difference is very minor.

Were their tubes straight? How do you think they got them? (they mail-order them,,,)

I don't know why you need it, but be warned that some kinds of stainless-steel can be very difficult to cut with anything except a grinder. And stainless can chew grinder cut-off wheels up pretty fast too.

Hi, this thing in the picture is a pipe in my backyard that's just been there since we got the house. According to my mom it's a well pipe and once you get a pump out will run water.

Thoughts on this? What kind of pump would we need? Or does it not even work?

My receiver will not time beyond 102 MHz if I use the knob on the front. If I turn the sheave connected to the tuning capacitor, it turns with some force required to get past 102, but past that it moves normally. It will also turn back normally, but then it won't go past 102 again.

>>998682
Stick your face on it and inhale really hard to see if a bunch of water gets all up in your face.

But seriously, if the rest of your house is on city water it's definitely something worth looking into. Basically free water. All you have to do is pay for the pump. The condition of the well should be on a disclosure form from when you bought the house. Could be capped for legal reasons and you aren't allowed to uncap it. Could be in perfectly good working order and ready for a pump. Could be filled with deadly deadly poison stuff.

I want to coat half a log douglas with epoxy, with bark and all.

Shit, I didn't even ask a question. It also turns using the tuning knob if I give it some speed.

What should I do to fix it?

>>998703
Yeah, we don't have a disclosure and not anymore. And yeah we're on city water, I'm in the middle of brooklyn.
I don't think it's capped for legal reasons, the people that lived here before apparently used to have a whole vineyard in the backyard for making wine, so I think it's likely they used the well for it. Probably a good idea to also mention that we've had this house now since 1998. So almost 20 years.

Any clue what kind of pump for it though? Searching for well pump brings up a lot of different stuff, and I honestly have no clue how this would work.

>>998725
The type of pump you will need depends on there well. There are a lot that will probably work, if the well isn't dry or capped off, or a number of other things that could wreck it. Might be worth having a well inspector come take a look at it. Then be sure to keep a copy of whatever he says, so you can use it when you sell the house. Even if you don't decide to get a pump for it.

I have an old electric typewriter that I got for free after clearing out an old death house. Problem is, the space key locks up the "advance one step" mechanism and shuffles the paper to the end of the margin almost every time I use it, unless I physically hold it back.

Also, the X key just... Fucking pounds on there. It's like a machine gun, tatatatatatatat, whereas the other keys are normal and only trigger once when I hit them.

I've looked around online and save getting an account at some autistic typewriter fan forum and asking there (didnt find any forums), haven't been able to locate any information about my brand/model that lets me request a manual or similar.

Does anyone know if there's some kind of quick and dirty fix? Should I dismantle and clean it and hope that works, can I test it with a multimeter?

Sorry for this torrent of retarded questions. I just really wanna be able to write stuff without having to use a computer, and my portable typewriter is a shit because I have to slam the keys so hard for them to register stain onto the paper well enough.

We have a broken trampoline in our backyard that needs to be thrown out. Everything is in tact except for some crucial support legs. What can be made from the salvaged parts?

>>998385
i do not think the str is being driven into clipping as that is not consistent with what i see on the scope (ie no rounding or flattening at the top of the waveform.). I figured a big cap would short some unwanted harmonics to ground and leave me with a beautiful sine wave.

Interestingly I increased the 47k resistor you mentioned to 330k because I was getting only faint effect and a lot of thumping and now there is less thumping (only when the speed and depth are >75%, say, and it is quite faint). I fiddled around a lot with it today with the output voltage divider and swapping cap values to get a speed range I like and it sounds good, except that now it seems to eat up a lot of current that was going to the reverb tube on my amp, for when the trem is up high and the reverb is up high, there is a fizzly sound that definitely is coming from the reverb section. The oscillator is fed from the same node as the reverb tranny. More dicking around tomorrow I suppose.

Your input is appreciated.

>>999299

While concerns regarding expense are valid...

>[they] go to shit so fast

...is outright wrong. Even the no-name Chinese packs covered in duct tape will last quite a while. More reputable batteries will maintain >70% capacity after 2000 cycles.

Gas will definitely be substantially cheaper. For reference, I just "finished" my electric bike yesterday, and the battery (375Wh nominal) alone ran me nearly $200. Keep in mind that I not only got an excellent deal on the cells, but I had to build the actual pack myself and add a BMS + all the little shit that adds up.

At the same time, however, gas will be more maintenance intensive and you're liable to be stopped by the cops more than once. I have no idea what your intended usage pattern is, so I have no idea which you'd be better off with. I went with electric simply because I intend to use my bike as regular transportation to and from work. I don't want to be fucked with small engine maintenance, smell like exhaust fumes, and can't be late because the new guy at the police station (which I go right by, BTW) doesn't know whether it's legal or not. If you're just dicking around now and again and don't care about any of that, there's no reason not to use gas.

If its parallel to the beam just friction fit( wedge the upright studs between the top and bottom stud plates) it to the beam.

Construction adhesive can keep it place. Hell even powder actuated nails will go through a steel beam.

If perpendicular just frame the wall with a notch in it

I need help finding a router bit that would work for a project of mine, but I don't know anything about routers.

You could, but there's Inge tiny little problem with it. No chain, which means you'd have to rig something up to drive the wheel.

I'm working on a project that currently has a brushed DC motor. The motor is creating a massive amount of electrical noise and is interfering with the rest of the circuit. I've tested random brushless motors and they work perfectly. My question is where can I find a brushless motor that is the same size as the brushed motor I already have. Google isn't returning anything particularly helpful. The motor needs to fit the following specs:
diameter 24 mm to 30 mm
length preferably 30 mm, no more than 32.
shaft diameter 2 mm (this could potentially vary assuming it comes pre-assembled with a 5.9 mm, 11 tooth gear.
Voltage rating is somewhat negotiable. I'll be running it at a max of 10 V. I'm not terribly concerned about running it past it's voltage rating as long as it isn't going to burn out immediately with light to moderate use (2 hours constant at most.)
Unfortunately I don't know what the rpm rating is on the brushed motor and I don't have an easy way to find out. The only other thing I can add to that is I tried replacing it with a similarly sized motor I gutted from a printer and it ran at about half the speed as the original when I put 10 V across it. I think the printer motor is a stepper motor??? I don't normally into motors.

nah dont do this. your option is to fill and seal. you can't fight timber that wants to tear itself apart.

I have a Whynter dual hose AC unit, supposedly more efficient than the single hose designs because it maintains equilibrium with the outdoor air rather than constantly exhausting hot air outside, which will always draw air from the outside back in because of the negative pressure. I got it because my 'study' was by far the warmest room in the house but I spent the majority of my time there. The HOA forbids window-mounted AC units (and I personally think they shittify the look of any house anyways). So in use I would set the central AC to 82 degrees, while I kept the study at 75 with the Whynter unit and compounded the cooling with a Vornado fan aimed right at my face.

Using it was a nightmare because of how insanely loud it was.

Worse yet, the unit proved so much less efficient than the central AC this whole scheme made my power bills go up.

I found that my best solution was to set the furnace fan to run almost constantly while the AC isn't running, to circulate the air and even out the temperature differences in various parts of the house, while drinking plenty of ice water and always having a fan aimed right at me. The portable AC unit lives in the basement now for occasional dehumidifier duty.

Well(ha), I measured how deep it is with a long fishing wire and a heavy metal thing. Then I couldn't really tell how wet it was and after some confusion the metal thing got stuck and we had to let it go and it fell in...
But that's besides the point, after that I used a tube and found out that it's about 15 feet deep, and about 4 of that is water. So it means that I'll need a shallow well pump. But how do those even work? It's not particularly clear, I'd have to stick something down the pipe to get the water up, or would I just have to screw something on that cap that your see there? The latter is what I thought would make sense and what I hoped for, but it seems they're not that simple.

filthy cheap generators and what maybe someones expensive amp(s), its not the best combination - laptop, you maybe only blow the power supply. Also noisy af, and not especially suited to whats prob gonna be 6+ hours constant operation.

>>1000999
Yup, if constructed to code there'll be a timber running right above the doorway, behind the trim.

>Were their tubes straight? How do you think they got them? (they mail-order them...)
They probably order in bulk from nearby providers, ordering a pair inside a bubble package increases the chance of receiving them damaged because 2 tubes won't oppose as much resistance ad 50, specially if they come all the way from china.

>>998353
Try McMaster Carr. They ship and their tubes come undamaged. Not sure if you can get that big though.

So I am interested in learning metal working like machining and welding. I already was taught how to be a Plumber by the Army so I am not completely clueless if you throw me in a shop, and I have watched a few rando YouTube videos of guys working on various machining projects. I will like to get a mini lathe and mini mill, as well as some welding equipment one I am ready. I may upgrade to CNC someday if I get the cash, because the technology looks amazing.

My primary question is how do I get started down this path of learning? I'm looking at getting a tabletop style mill in the $6-700 range right now, followed by a lathe of similar price.

>>1001088
If I was you, keep in mind I'm a poorfag though, I'd start by getting either a flux core or stick welder. Neither require gas, which is a huge expense for a DIYer. If you choose flux core, get one that can run MIG too, because you don't wanna have to buy two machines when a lot of them can do both. And if you choose stick, get a stick welder that has AC and DC. A lot of stick welders can be converted to TIG, or hell, a lot of them come with the stuff to make them do tig from the store.

Now, flux core and stick both have the benifits of welding outside and in light winds. Stick is great for welding thick stuff, and is very strong. Plus you can literally burn through paint and rust if the wed doesn't need to be too strong, making it good for artsy fartsy shit and farm repairs. Flux core is better for thinner stuff, because the thinnest you can 'safely' weld with stick is 1/16th inch. And even at that thickness you have to exert a lot of skill to not burn through the metal. Personally, I like stick better though. It's a fun process to run, and there's a huge variety of rods for different metals, plus its cheaper than buying wire.

And of course you're gonna need an angle grinder and possibly a metal chop saw or plasma cutter too.

And the reason I say get a welder first, is because you can get a good brand welder all day on CL for 200$ and then cut all your stuff by hand until you get to the point that you need more accurate cuts and all.

My dog partially toppled a wall today (he always 'tackled' it when rushing to look over it and bark at strangers). It came out in two pieces.

>I have a gorgeous oak slab in my shed, i sanded it very very smooth, but it is starting to crack down the middle
>If i do as pic related, will this prevent from further breaking apart?
Thick and big wood tends to do this. The thicker and bigger the piece is, the more likely it is to do it. There is no way to stop it as it is.

Annoying fact: wood expands and contracts with changes in atmospheric humidity. This is what makes it warp and crack. The only way around this is to cut thin layers and glue them together in alternating directions--which is what laminate and plywood is. If you had a HUGE tree and tried to cut a 3/4" slice from it that was 4 x 8 feet, it would NEVER stay flat and not crack. This is why they don't sell pieces of wood like that.

Ideally what you would do is saw off a thin/facing piece, like 1/4" inch thick or less, and then glue that down to a sheet of higher-grade plywood (such as marine grade plywood). The top will still look nice when finished, and it won't warp or crack. You would be basically making your own laminate from it.

>Will a simple generator such as in pic related be enough to power the speakers, a laptop and some lights?
Open-frame generators are noisy as fuck, don't even try it. You won't like it.

What you need is a few large batteries (car batteries would work but ebike batteries might do better) LED lighting and a QUIET generator in case the car batteries can't keep up.

I dunno what it is right now, but for a long time the quietest small generators around were the Honda EU2000i ones. $1000 for 900 watts, which is way more expensive than the China brands, but the Hondas run quite a bit quieter.

Brand new /diy/er here, I have no tools at all (aside from an around-the-house toolkit I bought years ago) for any of my future projects (which hopefully will include casting aluminum and possibly lead, blacksmithing, some woodworking, gardening and landscaping as well as beekeeping)

>>1002215
>how do i make it look "nice and shiny?" is that through sanding or polishing?
Sanding to smooth out the rough form then polishing and applying a lacquer or sealant of some kind, it largely depends on what you're using the wood for, but mineral oil and boiled lynseed is common, along with a whole slew of other commercial finishing varnishes.

>>1002499
It's full of "is this a meme?" and "is that a meme?" 'go 'za (Chicago deep-dish pizza, which is used as a trolling technique) and fast food/dinner kit (like instant ramen noodles) discussion ad infinitum. People who actually cook are at best ignored or shunned.

I've been on /ck/ daily for the past week and I've noticed not a single other person give out clear-cut recipes or discuss the benefits and detractions from using method X vs method Y when preparing a dish and only a handful have given out general guidelines on cooking at all.

And speaking of cooking: there is no cooking shown. None. Look through the whole board and you'll be hard-pressed to find anyone posting anything they've actually cooked. It's just stock photo after stock photo.
There are, out of 150 open threads right now, only five showcasing the OP's own handy work. And they're each trailing abysmally behind the troll threads and arguments over fast food and bad shit like that.

Go on craigslist, find the largest lathe/mill you can accomodate in your budget. I bought a $300 mini-lathe, and then a $600 middle size lathe(11in x 40in). Didn't bother with a benchtop mill, with a middle size lathe you can do those operations. I went ahead and picked up a large horizontal mill for $200 from the scrapyard, not working, currently working on fixing it up, should be another 200-300$ before it is running. Buy the biggest equipment you can afford/live with, or you will be limited in what you can do.

Yes, several times. Usually, it goes mostly ignored, never above 25 replies before pruning to the archive. A few times, the threads devolve into name-calling and trolling for reasons beyond my comprehension. The only successful thread I made, which went over 300 replies and pruned naturally due to autosage, was "Breakfast, Lunch and Dinner" where I posted pictures of what I cooked/bought to eat that day and a description of the meal, encouraging others to do the same.
In that thread, people asked for recipes from each other according to the pics they say and the descriptions they read.

Someone else continued it, even saving my picture, but the thread eventually died due to lack of participation.
Last year, I tried to promote OC by suggesting theme meals IE where anyone posting pictures should post a meal that followed a theme ingredient, theme food type (like chicken sandwich or fruit pie) or culturally-inspired cuisine theme (Japanese-inspired, Italian-inspired etc). After a week of trying to keep it going with little to no participation, I just let it die.
It was sad.

Look, I'm no chef or professional. I like to cook and see what other people are cooking as well as give and get advice on how/what to cook.
But that just doesn't seem possible on /ck/ right now because very few people are interested in cooking and would rather argue over whether Papa John's or Pizza Hut has the worst pizza.

>>1002230
Paint remover / acetone and a cotton swab. The body is likely powder coat or an electrostatic paint and will be much more durable than the screen print. The white will come off long before the black is damaged.

Set up a camera with motion detection somewhere nearby. They're like $40 on Amazon at most and they'd trip the alarm before they touch the tank, giving you more time to respond. And you'd get video of them.

>>1006091
How long do you need it to last? A heavy coat of exterior oil-based paint will keep it "for a while."

If you need it to last multiple seasons take a sharpy, and use the piece of wood to make a sign advertizing that you're sucking dicks for $20. Suck two dicks, then buy treated lumber or PVC. Suck four you can afford marine grade ply.

>>1006110
A "while" will be fine. I'll switch to something better when I can get something on the cheap.

One of the ports in my powerboard has randomly stopped working. Anybody know what that is about? All the other ports are working fine but the port second from the end no longer powers anything, does not matter what I try to plug in there.

All switches are on and everything. Happened to a second powerboard today which is why I came here to ask wtf is happening. One powerboard I can put off as a fluke of shitty design, but two?

>>1006414

the chinks are now using lead-free solder on everything, which is crap, coz of EU regulation, which ccan male connections pop loose. also, workmanship is not valued, just speed, coz ''time is money, bitch''

the second-most probable reason is that the contacts are bent coz they use cheap materials. in both cases, you can open it up and remedy the situation fairly easily.

Hey /diy/, its been an incredibly shitty week and I'm not thinking too straight so help me out.

The blower motor to our swamp cooler apparently just died. My mother and sister were complaining that the air wasn't cold enough (no shit, its 100deg F and high humidity right now!) so I went on the roof to check the water pump. Had them cycle the cooler to pump only and lo and behold the pump was working just fine but when I had them cycle to cool or vent settings there was no response from the blower motor.

It had been working fine the last few days up until I had them turn it off so I could check it. No breakers were tripped and the water pump and blower motor run off of the same circuit.

Is it safe to assume that it is purely a problem with the motor and not any of the wiring leading up to it? The motor is over 9 years old best as I can tell.

Well /diy/ its officially summer here in Indiana. The problem is, I am the very last room in the house that the air conditioner reaches, so I get no air at all, and my room is in full sun. It is regularly 90F+ and I spend the summer sleeping in the cellar where it is cool.

Problem is we are redoing our cellar and I can't sleep in there this summer, so I'm stuck in the oven. Is there anything I can do to the AC/duct work to draw more air to my room? I tried replacing the filter and shutting every other vent in the house, but I still get nothing.

Would it be cheaper/more practical to just buy one of those window AC units? I've heard they are junk, but I'm sure there are quality ones out there. If I go this route, would a 5000 BTU unit be enough for a 15x15 room?

I'm sorry my post is more what should I buy than what should I make, but this is the most relevant board we have for it.

>>1006775
How's the humidity? If it's not too high (<50%) make yourself a swamp cooler. It'll cost maybe $50 in materials, and can keep you comfortable in up to mid 90s outside temp.

I'm about to build one this weekend. I read a bunch of online guides and will be designing mine as a combination of a few.

>>1006765
>Is it safe to assume that it is purely
a problem with the motor and not any of the wiring leading up to it?

assuming nothing, test everything.
- turn the fan manually to see if motor is seized
- hook up voltmeter (or lightbulb) across the motor terminals to see if it's getting power.

if it has power and is not seized, then you can make assumptions about the motor. and it's not necessarily dead; could be a blown thermal fuse, which only costs a dollar, but isn't easy to change.

I bought these files at a flea market and I feel like I got ripped off, what do you think they're worth?

>>1006841
Maybe $.50 in scrap, depending on where you live and what scrap prices are.

Everybody forgets that files are consumable goods, like driver bits, and hacksaw blades.
If the teeth are still good, good for you, you possibly saved some money over buying a new file, but they're probably shot.
You bought garbage, congratulations.

>>1006775
Is it possible to add an in line fan anywhere ?. Or is this putting a band aid on the problem ?

>>1006841
Depends.
I have paid anywhere from a quarter a piece to a maybe 4-5 dollars.
It really depends on how good of shape they are, what they, and how im feeling at the time.

I also have a ton of old files already, so I tend to not spend too much on them unless something catches my eye about them.

>>1006841
As files, probably scrap value unless you lucked out on the teeth being good. But if they're decent steel you might make punches/chisels out of them, especially if you could use something nonstandard.

>>1006775
>would a 5000 BTU unit be enough for a 15x15 room?

yep, if you keep the door closed. personally i'd spend another $50 for a 7000 BTU unit so it doesnt have to work non-stop on very hot days. in my experience, even the cheapest units, like a Sunbeam, will last 5-10 seasons before they start to act screwy.

another cost you have to consider is the acrylic plate over the A/C. a 1/4-inch thick sheet can easily go to $40 if it's bought new. that's like 50% of the cheapest A/C unit on sale.

>>1006788
Alright status update: haven't had a chance to test with a voltmeter. The cage/pulley/motor all spun freely when I checked it earlier. The blower turned on after about an hour of just sitting, couldn't trouble shoot more due to a funeral.

It's sounding like a thermal safety switch shutting it down when it overheats, if it were a fuse it wouldn't power back on right? Going to have to figure out if the motor is overheating due to age, too tight a belt, or ???

Does a sort of small valve with a pushbutton to open it exist? I have no idea what to google for.
What I have in mind:
[balloon] -- [valve] -- [tube]
Only when the button on the valve is pushed air can go in our out of the balloon. Doesn't need to be high pressure or anything, just airtight.

>>1007070
I found out that a slide valve might be what I'm looking for. But some of the ones I find for sale have a minimum pressure rating that's above 0, what exactly would this mean in my application?
I'm thinking if I close the valve it would still leak air if the pressure from the balloon is below the minimum?

Why isn't the current flowing?

I tried this in real life and the current flowed. What happened was that one of my generators output wire was touched with the generator body. I used a tester and I could detect voltage. So for fun I took a ground wire and touched it with the generator and there was a pretty neat spark.

>>1007221
You only connected one end of your AC source.

>>1007221
Okay but can you explain what I said about the generator. Wasn't it a case like that?

>>1007243
I found out that the simulator has a 1-terminal AC source. And it's now working as expected.

>>1007253
The one terminal source is just assumed to be connected to ground on the other side.

>>1007221
>I tried this in real life and the current flowed. What happened was that one of my generators output wire was touched with the generator body.
That makes sense then, because generally the case is grounded. So it made a complete circuit.

Lets say I have a 10HP motor hooked up to a DPDT switch "ON OFF ON" i.e. forward off reverse. Will it damage the motor if I switch from forward to reverse while it is at full speed? Will it slow down and reverse speed faster if I do this?

>>1007256
So the reason the mains power hot wire shocks people is because it's neutral is connected to ground?

>>1007266
yes. Thats why Isolation transformers can prevent shocks.

>>1007272
I am learning in so many things. This is great.

Another question if you wouldn't mind: Why does a portable generator have floating neutral and mains power don't?

Why don't manufacturers make cars with the heated horizontal lines on the front windows where they are needed the most?

>>1007280
It'd be obstructing the windshield.

>>1007279
Because the generator itself is floating. Like any other object, it's isolated from ground unless you deliberately ground it.

>>1007280
Blowing hot air on the inside works well enough, and is needed anyway to remove respiration.

>>1007287
Just takes a while for the engine to warm up is all. Some cars nowadays have a built in electric heater that solves the problem.

>>1007286
If one of the terminals is grounded the said terminal will then be the neutral?

>>1007302
Pic related. This simulation agrees with what I said. Is it correct?

>>1007260

it's entirely possible to damage a motor if you reverse it while running at full speed. you'll get a large temporary spike of current as the generated and applied voltages add. OTOH, motors are pretty hardy, so maybe all tha'll happen is that it gets briefly hot.

OTOOH, 10HP is a big ass motor, so i'd expect a very large current that'll blow the overload protectors.

>>1007302
>>1007317
Pretty much jea. However depending on your country you are or aren't allowed to use one wire for ground and neutral.(RCD's need them to be seperated to work). On the outsde of the house both are often layed as one cable.

Start with basics and buy stuff as you need them. If you're stripping screws or marring up surfaces, you're probably using the wrong tool, or using it in the wrong way.

Given that you're embarking on a bigger fix up (not just maintaining little things) you're going to have to balance the cost of tools against the time they save you. You can redo all the trim in your house with a hand saw and miter box, but a chop saw will save you a lot of time.

I'm trying to make a stealth truck camper with a good amount of headspace. I currently sleep in my 93 Toyota pickup with a regular camper shell and just have blackout curtains up. I'm looking at buying this work shell because of the extra room/roof height (I'm 6'3") and extra stealth.

My question is how could I best create a passthrough from the cab to the shell? Currently I have a sliding window in both the cab and shell so I just crawl through - obviously this one is just a solid wall, and I'm wondering how to make a removable, but still water tight, passage. I'm sure if I was savvy with this stuff I could just put a sliding window in the place where there is currently metal.

My completely uneducated and pretty useless brain thinks that I could just cut out the metal and put some sort of seal around it where I can just insert the metal back into...does this even make sense? I don't know, I have no idea what I'm doing. Any help is appreciated, thanks

i'd use an orbital sander to flatten it, stripping the paint isn't necessary and too labor intensive. Just using a paint scraper is fine too if you don't mind minor surface imperfections.

I was given a wind up clock movement, and it seems to work, but is very loud without being enclosed. What can I do to make it quieter? Getting a case would probably be best to lessen the noise and make it look nice, but I don't think I can make one and I haven't found one to buy yet.

Expanding on that I have two other questions.

1. What would happen if the neutral was not connected to ground at all? If someone touches a hot wire it won't shock them. Isn't that a good thing?

2. Pic related. Assuming neutral is grounded only at the transformer (left side of pic) and a person who is grounded touches a hot wire (right side of pic), does the electricity flow all the way from where the person is standing to where the transformer is?

Sorry for my stupid questions.

What is the base resting on? if it's on the ground then either will be fine because the load is being transferred directly to the ground.

If the base is being suspended off the ground somehow, A would be a better option, in B the load is resting on those joints, shearing them apart in A the joint is being compressed and all the joint has to do is hold the pieces from sliding apart it's not supporting any weight.

When I turn it on as a convection oven and preheat to a temperature of 220C or less it often tells me it has reached the temperature way before it has and then stops heating. So it will say it is 200C but it will actually be 90C or the like.

I was also going to try and fine some closed cell foam runners to stick in the window tracks and behind the rubber slip that's "Supposed" to make a seal between the two windows.


I did something like this years ago whne I bought the AC unit, I used the packing Styrofoam and cut a bunch of "insulation" blocks.

And it worked perfectly.

Anon, you're on a fucking DIY board.

Curiosity should never be punished.

Hell if anything I wanted to let him help me airseal the fucking AC-Units.
Way to be a dick my man.

>>1008668
ha

>>1008672

youre right, this is /diy/, let me adjust my suggestions

>>1008510
Pay someone to insulate it for you.

Could you point another air conditioner at it?

I accidentally put my cellulose acetate glasses in the washing machine. They came out deformed, and I was thinking about reheating them and mold them back into shape (CA is a thermoplastic).

My question is, can I use a cooking pot to this end? Are there any toxicity risks I should be aware of?

Thanks in advance.

>>1009020
Are they prescription glasses? If so, you'd never going to get them right again.

>>1009025
Pretty sure he is talking about the frames.

>>1009020
How badly deformed are they? I have used hot water to soften my glasses frames so that I could adjust the arms for a better fit. It is the same thing they do when you take them in to be fitted, they heat the plastic up and bend it into shape.

If they are so deformed that even the actual frame section holding the glass has been messed up then you might be in a bit of trouble.

What did you mean by this? The lenses survived. They went into the space between the washing machine door and the rotating body, into the rubber part.

>>1009026
The frames, on the other hand... This is what two rides in a washing machine make to you. However, given how the maximum temperature in washing machines is around 60 C, and I can get to 100 C by boiling water, I was confident I could manipulate them into their former shape.

Getting the lenses back in the frame is a different issue, but I'm thinking about something small to get them pinned in place.

Back to the toxicity, do you guys have any input on that?

>>1009044
>maximum temperature in washing machines is around 60 C
Are you sure they were not next to a heating element or something? 60C should not do that to plastic frames.

Those look pretty fucked, you might be better off taking your lenses in somewhere and getting them put in new frames. That is assuming your lenses have not had their coatings destroyed (probably have).

Toxicity would not be a problem unless you plan on drinking the water.

>>1009045
The WM was next to the dryer, but I don't think anything else was in place. I assumed that was caused by the temperature and forces over the frames.

My optician told me they don't make those frames any more, and that the new ones are bigger, so adapting the lenses is impossible. I'll try asking around.

I'll try it tomorrow then and report back. I hope I can get them back in shape.

I guess a follow up question about this is, could it be possible to adapt the movement to a donor clock case, especially to accommodate the winder. Or should I just get a new clock?

Would pic related work to make a powered USB hub? I could buy one, but I got that old standard hub laying around unused.

Not strictly DIY, but its hopefully a quick question.

The WiFi in my house does not reach one of the bedrooms, however it does have an Ethernet cable in it connected to the main router.

Basically i want a boosted WiFi signal in this room but my experience with the standard boosters in the past has been pretty poor (ones that both pick up the signal wirelessly and then broadcast it), what i want to know is are there types where i can plug the Ethernet cable in and boost a full strength signal from there? I know a lot have Ethernet ports on them but i get the impression these are to provide a device with an Ethernet link from the booster, not to provide the data to it?

sorry if this is blatantly obvious, just after the product type i would want to solve this issue.


Thanks

I'd ask consumerism /g/eneral.

>>1009117

you would want to make sure there's no power collision between the external power, and power coming in from the male plug. i'd use a 5.7V power adapter (they definitely exist for some phone chargers) and put a silicon diode in series with it. connect those 2 wires to the hub, not the plug.

>>1009131

the device you want is a wifi router configured as a repeater. some units do this natively, others can be flashed with DD-WRT (or similar). this option may be expensive, complicated, and may not work.

another solution is to use a ready-made repeater with ethernet output, like the Crystalview model A5. you set it up between the endpoints, the network sigal goes by wifi from the start point to the repeater, then goes by ethernet cable to the end point.

a third, and cheaper option is, if your end point is using a USB wifi stick, you can use a USB extension cable to bring it close to the signal. i've have good success with cables up to 15 feet -- at 25 feet it sorta works sometimes but is not reliable.

Some anon's LED circuit.

The LED's are probably 3.1 volts, but max brightness with no resistor is a bad idea. Using 2.8V and 10mA instead, 60 ohms. So 100ohms or 68. The second resistor would be 160ohms, so 100, 220, or 100+68.

More than 3 LEDs would not light off 9V.

>>1009609
Also, calculations:
Assuming 2.8V/LED: 3x2.8 = 8.4V.

9V - 8.4V = .6 volts left for the resistor to drop. Assuming 10mA current:

.6V/.01A = R = 60 ohms. Round to nearest standard resistor values, preferring higher values: 68, 100, or down to 47.

I ended up fixing the the receiver by replacing the dial string. The original string did not have the proper tension. It started to get loose around the 102 mark.

The bridge on my guitar just cracked in two a while ago.

Is a good idea to try to bond it back together using either wood glue or JB weld? Or should I just find a replacement bridge?

I want to do a art piece that would be easier if I could pour layers of resin, let it cure, then continue pouring sequential layers of resin. Would there be banding? bubbles? I'd like to be able to pour like 1/4 inch at a time to thicknesses of 3 inches or so

Can't hurt to try.

What's the most powerful infrared blaster I can get easily?

Is there any reason I shouldn't build a geodesic dome in my living room?

>>1008138

>>1009939

rooms are rectangular, domes are round, so you get a lot of wasted space. now, if you lived in a yurt or a hobbit house, then it'd be a different story.

>>1009950
But I want my cool spaceship that's also a bit quieter inside except for the HEPA filtered air forced in so I don't overheat.

Why aren't walls/floors constructed so that they meet? As far as I can tell, there's a gap and it's so that carpet can appear seamless. From what else I can tell, it's also the main ingress point for crawling insects and spiders, which is something I'd love to eliminate.

>>1010114
Lifehack: Leave the spiders alone and you'll have fewer of both. Assuming you're far enough north that non are dangerous.

>>1010116
Not really material to my question.

I'm not trying to kill anything. I want them to stay out of my living space. It's a win-win for me and the spiders, as bug traffic in here is generally low to begin with. But if I know there's a spider, especially above a certain size, I become paranoid and can't sleep. It's not something I can just switch off by telling myself it can't kill me.

Is the gap there so that the room can breathe, or to accommodate material expansion/contraction? I just don't see a reason for it other than "the customer doesn't see it"

>>1010114

the drywall installers use a lever to push the drywall tightly up against the ceiling before nailing/screwing. so there needs to be a gap to accommodate the lever. also, it allows them to be approximate in their cuts. since the floor is often not level, they'd need to scribe a complex line and cut along that line if they wanted a tight joint. that would cost them several minutes which are better off spent getting high.
