Welcome to /SQTDDTOT/, where there are no stupid questions, only stupid anons. At least try to google it.

How much of a difference does bolting a mini lathe to a concrete floor increase in its rigidity/cutting accuracy compared to a 1/2" plank of wood?
What is the easiest way to bolt a lathe bed to concrete?
Does it matter if its level or not?

[Anonymous No.1729561]

>>1729425
The rigidity of concrete is orders of magnitude higher than 1/2" plank. It will greatly improve accuracy.

Drill holes in concrete with masonry bits. Use allthread epoxied into the holes in the concrete. MAKE SURE THEY ARE PLUMB (straight up and down).

Level is of extreme importance, as gravity will always and forever affect whatever you are doing with your lathe.

Hey /diy/

I recently obtained a nice, new electrical oven for free. Problem is, my kitchen is fitted for a 110v oven with gas. The new oven needs 120/240v with 40amp supply.
I jewtubed how to add the new line from the mains to the new socket from a few sources, easy enough for me to do on my own.
But my mains looks like pic related. I'm not sure how to properly take off the cover in order to add the line + breaker. Obviously I dont want to fuck with it before knowing if the live external feed part of the busbar is open along with everything else. Maybe I'm overthinking this though and should just unscrew it from the mount?
>Inb4 call an electrician.

Any tips guys?

[Anonymous No.1730096]

Watch a lot more YouTube first. Everything inside once you take the panel off will be energized, and once you flip the breaker to turn off the panel, part of it will still be energized. You have to know which parts these are, and what you can and can't do at what point, before you even pull out your screwdriver. If you proceed, read/watch everything you can find about it, then think real hard about whether or not you like being alive. And that's not even addressing running new wire and the pain that could be.

[Anonymous No.1730100]

>>1730096
Yes I understand how busbars work.
Why I'm hesitant to take off this cover mount is precisely because it tightly covers both areas on either side of the main shut off and I dont want to be found zapped with a stupid looking flat tip screwdriver in my hand.
I'm fishing for someone who has worked on a similar style case and knows what to expect underneath.

I got a couple old (corded) tools that sometimes don't start when I turn them on/pull the trigger. I have reseated the brushes as well as disassembled them and put them back together, but I'm not an electrician so I have no idea wtf I'd be looking at.
One is a die grinder and it seems to have like, a "dead spot" in the rotation if it stops there and I try to start it up again.

The other is a recip saw that almost feels like holding it at a specific angle makes it not wanna go without a shake.

Neither have boards inside, they're old as fuck. I'm not particularly bothered by them working intermittently (grounded properly inside) but it's kind of annoying and I would like to know what's likely wrong so when I do have the time I can tune them back. Plus it could be making them less powerful than they should be, right?

If there is no screw under the top cap the only other place I would know to check is between the handle and the body of the faucet - see if there is a screwhead that becomes revealed when you lift the handle, if so it will likely require an allen wrench.

Sup guys, I'm fiddling around with the design of a fixed-wing drone that will have a large cargo capacity. I expect that at takeoff the cargo will weigh about 4X the empty weight of the airframe/engine/fuel, so let's say 800lbs cargo and 200lbs everything else.

With an overall aircraft weight of around 1000lbs, it's going to require a lot of takeoff power to get moving and get into the air. I am thinking about using a pulse-jet as a sort of rocket assisted takeoff. Once airborne, an ordinary piston engine will sustain it in flight.

How much thrust do I need to get out of the pulse-jet engine? Assume takeoff velocity will be, say, 50mph or so and it will use a high-lift at low-speed airfoil such as an S1223rtl-il. Would 100lbs of total thrust be enough? What percentage of that would be needed for sustaining flight once airborne?

Well... given the questions and numbers you throw around, fiddling is the right word.

Plane design is the wrong thing to fiddle with, so perhaps you'd want to educate yourself a bit more to avoid, uh, disappointment and mayhem in your future in the unlikely event you build a thousand pound drone and manage to get it airborne.

I don't know you, and don't know your accomplishments or capabilities, but sincerely, I can tell you that craft design is not your strong suit.

I like how you drop the airfoil spec like it's no big thing, but... why not a GOE 226 (MVA H.36) or
GOE 225 (MVA H.35) , or
GOE 234 (MVA CA5), or
GOE 227 (MVA H.37)? They all have very similar characteristics to the S1223rtl.

I was going somewhere with this, but I lost interest in whatever is that you propose. I just have the vague notion that you're full of shit and pretending you're doing something you're not, but I just don't care anymore.

Go build it and let us know how you make out.

I havent been able to find anythin already made in craft stores or jewelry aisles, so I want to make one but if I glue the edges, the solvent might eat away at that as well. is it possible to melt edges together, or is there an existing glue that wint dissolve in anything?

As hard as running a brand new wire to the outlet from your electric panel.

You might be in luck. Silicone sealant (used for fish tanks, but you don't need the special fish tank stuff) is actually pretty resistant to most things.

But please note well: Industrial sized plastic solvents come in metal cans, so if you can get some tinplate that you could solder into a container (or even a cookie tin that *doesn't leak*) then you probably want to use that.

Hello. I recently got the music player in pic related (AGPTEK A02).

It's a halfway-decent music player, but it has several bugs that sour the experience for me (mostly related to how it organizes songs and how there's apparently a 4000 song limit, but haven't verified it for myself yet).

I've heard that it's possible to flash code to these things, but I have no experience tampering with consumer electronics, especially ones that interface with code.

My question is, if I want to flash code to this MP3 player, what are the things I need to know before tackling a project such as this? I've heard of the "RockBox" Operating System for MP3 players, and that might work, but I don't know how to make sure it's compatible with this player, or how to upload code to this.

Any and all help is appreciated

I have a sugar cane press I want to motorize. I know a bit of electronics, but basically shit about motors and gears. My first thought was to grab a motor out of a garbage disposal, and either hook up to a pulley system, or just directly attach it to the spindle. Then I find out many of the motors are going to be running at a fixed rpm of like 1700 rpm, and I need about 30-60. ( ideally with the ability to adjust the speed a bit down the road if it is too fast or too slow.

1) Can I decrease the speed of the motor by reducing the AC voltage? This would be the easiest fix - just get a variac on there or something.

2) Is there a better existing motor/gear that I can grab on the cheap from an existing system. I was thinking of a powered wheel chair, or those Jazzy things - adjustable speed, high torque, and I can find broken ones pretty often on local auctions

3) I don't suppose anyone can guesstimate how much torque I need ( just ball park ) for a person turning one of the wheels you see on the photo. I have no frame of reference of the amount of torque to turn a door handle, or a bolt or any of that shit.

You can see someone using a pulley system, but this look dangerous as shit to me. Seems like way too many RPMs compared to what mine requires. I'd also like some sort of deadmans switch you have to hold down to make it run.

Depending on what's around your ground rod/how deep/long your trench is, you can always lay the ground rod flat (horizontal). I've worked on jobs where the state inspector lets that fly once we encounter rock after the first 2-3 feet of the rod got driven in. And this was after using a jackhammer with a ground rod driver attachment, much to the contrary of the other tryhard poster who says "dude brah just dont b a lil bitch brah c'mon breh"

Got a basement floor with 9x9 assumed asbestos tiles. I’m gonna put that interlocking vinyl floor system over top of them but I want to put some epoxy paint down first to seal it all up. I’ve looked at the procedure for laying epoxy basement paint and they all say you have to roughen up the floor (which sure as fuck ain’t happening) and then use muriatic acid (which I also don’t want to do). Any objections to using an acrylic primer/sealer (after a good scrubbing of course) before laying down the epoxy paint? And don’t say “just use a floor leveler” because I realllllly don’t want to do that. Keep in mind there’s gonna be a moisture barrier underlayment in between the tiles and the vinyl.

You're twisting the saw. Don't push down when cutting, slow down, take shorter strokes. Also, make sure your arm motion is parallel to your cut, through the entire stroke. If you're right handed, try moving a half-step to the left from where you think you should be.

It looks like you are trying to crosscut right down on the short edge.

You could get a business license with certifications for each service you want to able to sell. I'd recommend the things that most laymen have trouble with during each season. HVAC repair in the Summer and Winter, fridge repair in the Winter, pest control and gardening in the Spring, leaf collection in the Autumn, etc. You could be an all around handyman/jack of all trades. Just gut a truck, maybe a box truck, and one of those metal truck beds you hitch on your truck. Do some trash pickup and special collections that people can't be bothered to pay the city to do, or what the city legally can't collect. Idk, just wanna contribute something :)

I have six COB LEDs I'm growing tomatoes under. If I have any idea what I'm talking about, and I'm not sure that I do, the lights are only on during one-half of the alternating current phase, causing a rapid blinking that I can't see but shows up in pictures due to the refresh rate on the camera on my phone.

Can I just reverse the polarity on half of my lights to get better photos, or does polarity actually matter on alternating current?

Does anyone have an MPCNC and some opinions on it?

It comes in a few variety with the original MPCNC, Burly MPCNC, and the Lowrider MPCNC. I've considered making one as I would have space only for one, but I'm not sure which would be the way to go.

Tom from the 3D printing community made the burly but wasn't too happy with it, but that maybe slanted a bit from creative differences. There are a number of mods designed for the original to help make it more rigid as well and it seems the one with the most backing in that way. And the Lowrider can make short but longer objects with more stability which is nice also.

Looking to make some wooden swords and fun stuff like that mostly. Maybe a table top or two. Would love some input from someone with a CNC if this thing is worth making of them, which one, or if its just too hacky to be worth the investment.

I'm in a brand new house. The lights in the living room and the office occasionally pulse. They're on separate circuits. Not full on flickering, they'll stay on but you can tell they're dimming and brightening. Sometimes its really subtle, other times its more obvious. It doesn't happen all the time. Sometimes they're totally fine, other times not. Only notice it in the evenings since thats the only time I actually turn on those lights. I had an electrician come and check out the house and he couldn't find any problems. I called my power company, they checked out the junction outside didn't find any problems, installed some power monitoring device for a month and didn't find any issues from that either. Any ideas what the issue could be? My only option right now is to call a second electrician to check out the house to see if he finds anything.

Could be an appliance draining more power than it can support for both. Had a house where you could tell when the dryer finished that way, but that house was far from new.

Could also be an incompatibility in the switchs/dimmers and the type of bulb in the socket. Like for instance light switches that illuminate when off using a small amount of power. They work fine with regular bulbs, but that small trickle is enough to light up low watt taking LEDs or CFLs and cause weirdness.

easiest way is to do it is while the appliance is live and powering its load. activate the relay and measure voltage (could be AC or DC) across the contacts. a clean relay will show a few milli-volts, a dirty one maybe tenths of a volt.

some relays are case-less, and others have transparent cases, so you can see whether the contacts are golden or blackened.

older fridges use a motorized switch that usually does 8 hours of cooling, followed by 20 minutes of defrost. looks like pic related, and is often installed in front of the device for easy replacement coz they die after a few years.

newer fridges allow you to program certain things by fooling with the light switch. you can for example, force defrost to go on.

I'm preparing to open a large westinghouse tv (model dwm48f1g1) to disconnect the board that controls the buttons on the side because the tv scrolls through channels automatically. but I'm a bit worried about safety. More precisely I worried about shock from excess charge on the caps, failing to replace grounding wires or similar mechanisms, and any problems caused from leaving that board disconnected. I've read so far that most-but not all-modern TVs have something that automatically discharges the caps. In the case that it doesn't, they can be discharged with a screw driver or some method with a resistor. The TV has been off and unplugged for about a month, and I occasionally hold the power button down.

Anyway here are my questions:
Does anyone have experience with this model?
Is there a way to identify what ever component auto discharges the caps?
If I leave the board with the buttons disconnected, will it be dangerous to open it a second time since I would be able to hold the power and let it discharge?

First thing coming to mind is that if you wall was moldy, did moisture go there from the inside or outside? Where I'm from the indoors are never humid enough to allow mold to grow on your walls (relative humidity of ~25%). Usually houses without capillary break, and insufficient waterproofing tend to go moldy.

This seemed to be an okay image https://basc.pnnl.gov/sites/default/files/images/Complete%20capillary%20break.png in English of the matter.

Now if there's no moisture getting in there anymore, you can work on the inner wall. From the looks of it, you were too hasty doing the groundwork. Use white filler stuff and sand it, repeat until everything is perfectly even and smooth to touch. Let it dry between applications. If the base is pretty close to your finishing paint, you don't really need a base paint. Just a good quality normal paint, two to three layers of it.

Sorry for the bad terminology, never discussed this stuff in English.

Probably the wrong board for the question but I figure yall would be the most knowledgeable

So there's this high pitched ringing at my parents house. It happens once every 30-60 minutes for about 10ish seconds.
Its pretty high frequency, sounds kinda like a dog whistle. My parents can't hear it but me and my sisters all can so its definitely a real thing.

Anyone have an idea what it might be? We haven't really been able to pinpoint what it is.

I want to add some lettering to this. I was thinking about those rub-on transfers you can get but, from what I could find online, the selection of fonts was pretty lame (same for stickers).

Can anyone recommend a supplier (that ships to the UK) or perhaps even another method of getting lettering onto it (I may varnish it afterward so the letters would have to withstand that).

Use an app like Spectroid to get a rough idea of the frequency and direction it comes from and work from there.

What are these called? I want to buy some for a project I'm working on. I thought about bending some small diameter steel tubes but I don't have anything to bend them with, and this is probably a one-off project, so I'd rather just buy a couple pre-made ones. I need some that are like 2" long.

Try running a 12v incandescent light in parallel. Otherwise, there's a bunch of issues that come up when trying to run a motor off of a switching supply. Here's some light reading:

Saws, clamps, glue, screws, square, pencils, hand plane, sandpaper, chisel. That's all I used for the first few years of carpentry. Everything else is a nice to have or time saver. Maybe get specialist tools for marking and measuring if you want to other joints than box or butt.

So, about sound insulation, how i can tell how much each part of my walls conducts sound? Is there a somewhat cheap tool that can do it? I feel like most of it comes through the window and window frame but i can't trust my ears alone.

If my current setup is stupid what would be the cheapest and easiest way to run the pump off a wall socket?

I get what it means about the overload protection and all, considering it's a laptop charger that would explain it.


Should I maybe try battery powered? or maybe rechargeable batteries as a bridge between the motor and the wall socket?

I have very little experience with electric shit, but ima tryin.

OK so, if I have AA batteries that are...

2750 ma/h
1.5v

and I need 12v 3A

Does that mean if I link 8 AAs in series, I can run the device for...55 mins at 3amp?

>(A)=(mAh)/((h)*1000)
>3 = 2750 / (x*1000)
>x = 0.917
>mins = x*60
>mins = 55

Am I understanding this correctly?


Ideally I would like it to be wall powered because fuck paying for batteries, but this sounds like a decent backup.

Hello, I currently have voice activation for my smart home via Pocketsphinx on a Raspberry Pi using a webcam for audio. But I have to be in the same room as the webcam to make use of it and would like something I could fit in my pocket and at the push of a button transmit audio to the device for house controls.

Would a cheap walkie-talkie and a USB-SDR be the best approach for this or is there something simpler I am missing?

Find a linear power supply (one that uses a big, heavy transformer) instead, like pic related. These turn up at garage sales for under $10. Search for linear or regulated power supply.

This is probably going to sound bizarre, so much so that not even google knows what the fuck I'm smoking, but is there any way to turn sticky tape into plain non-sticky tape?

Just so I don't sound so insane I'll try to explain, I want to stick some tape onto a glass pane, but I want only the edge of the tape to stick. This is to shed water off some windows and bathroom doors, so I need it to remain non-sticky under humid situations, which is why I can't use something like baby powder as a solution. I also thought of folding the tape unto itself but I can't manage to do it perfectly so it just looks ugly as shit.

Why don't you just stick two pieces together (sticky to sticky side), leaving a bit with adhesive exposed. Then, trim to the shape you want.

Get a shitty drill bit set, drill the head completely off, and just lift the thing out. Grab what's left of the screw with a vise grip.

You don't have to worry about hurting the insert, it's way harder than your bit, hence the cheap shitty drill bit choice cause your gonna ruin it.

My DAC outputs a stereo signal but I have a pair of active speakers and also a powered sub. How can I split the stereo signal to both speakers and sub?

Do I need a receiver with 4 outputs and rewire the speakers and sub to make them passive?

You could try carefully, and slowly, heating the outside with a hair dryer to soften it up, and then applying a very light amount of a leather treating oil to the inside where you want to soften the creases/leather, and letting it soak in.
Saddle soap has solvents and other things in it that might be counter-productive to what you want to do, and you'll want to try light oil probably on one corner to test and see how well it works/how it affects the leather. A heat gun might warm the leather up too much too fast, depending on the setting on it - thus the hair dryer. Applying the oil on the inside might soften the leather up without altering the look on the outside of the bag, keeping the distressed look that you're after.
But as always, use caution, don't be in a hurry, and test in inconspicuous places that won't fuck up the look of the project if you're concerned about looks - and good luck.
