hey DIY am i going to die. I'm an EE student and touching high voltage stuff for the first time ever and I'm not sure if I'm discharging this right. ground wire's clipped, i'm just too afraid to touch the anode and get it over with.

2 MB,
I am hoping /diy/ can help me with this.


I'm no electrician and I also can't afford to have one come out to my house.

Here is my current wiring.

I have red, white, green, and yellow. But I also have a unused green wire.


The red wire seems to be jumped to power supply for cooling and heating (as there is only 1 red wire but two power supplies for my old thermostat) So should the single red wire just go directly to the new thermostat?

Thank you for the help guys. I'll post more pics

I live with my dad and stay up late at night working in my computer room, which is across the hall from my dad's bedroom. He's kind of old so he wakes up easily. I was wondering if I could use eva foam or some foam kind of like in my picture to make improvised soundproofing panels so he can't hear me playing music and moving around at night. I don't play music loud, but at night there's no other noise and I think the hallway affects how loud it is.
I'm pretty sure I remember past threads about doing this type of thing.

Why is there not a sticky with this already?

To significantly reduce sound transmission you have to increase mass, or decouple surfaces.

Those foamy things only reduce something called RT60, how long it takes for sound to decay by 60 db. In other words it reduces echo.

Yes, plastering your walls with mattress foam will reduce sound levels outside the room, but not significantly. He's still going to hear you.

It actually depends. It won't significantly reduce sound transmission but sometimes it's actually second-, third-, etc. order reflections bouncing off the walls and down/across the hall that cause the most discomfort.

so although open cell foam doesn't improve direct transmission much, it still will make the room, hallway, and house *apparently* more quiet and in a lot of cases that's enough. in other words, the direct sound won't be accompanied by a thick series of fluttering reflections...

Should I wet sand at a high grit? Or will the matte clear coat cover the marks? Maybe buff it? I can add another coat but would prefer not to add too much unnecessary weight.

So I'm about to remove my car radio and there's 4 bolts, deep under the dash.

I have a power drill with some bits to undo bolts (circled blue), I need some sort of adapter but I can't find any. The ones circled yellow don't fit. Does anything in the photo look as though it could fit the bits circled in blue?

In photo, no. Looks like you need a 1/4 inch socket adapter.

Best shit for car dashes is a 1/4" drive six point small metric socket set. Cheap is fine because fasteners are small. If a Ford, they LOVE 7mm hex bolts. A couple of 3" extensions, a universal joint, and a long extension like 12" will handle MANY automobile interior parts. I prefer deep sockets because some interiors have nuts on longish studs but shallow will do.

Top left, third bit from left looks like a 1/4in drive bit for those sockets. What makes you think you can change out a stereo if you can't even figure out a drill/driver?

Turtle's a hatchling, don't expect to have to upgrade for at least another year or two. When it's out of the 20L, I'll just fill it to the brim and suddenly I have more space for the fish! If it happens sooner than that, doesn't make a difference to me.

It's a tank to handle the water expansion when it heats, to prevent excess pressure in your pipes.

Where's it leaking? Did it rust through, or is it leaking at a fitting?

Looks like it would simply unscrew and a new one screwed on in it's place. Use 2 wrenches to keep the torque off the pipes.
Make sure the threads are clean, and use teflon tape on the new male thread.

I know a new cooker is probably best, but I'd prefer to fix the problem until I can order a new cooker. Britbong here.

The cooker has a switch on the wall, you press this and then the cooker turns on. Simple enough right? Well..

As soon as I press the button the light flashes on and then back off, and the lever has gone down in the fuse box.

It doesn't blow any of the electronics, the lights and TV etc all stay on, the only thing it cuts off is the central heating....

Does it only trip when you attempt to turn on a heating element(assuming...

Hi everyone, my dad is working on building his own pneumatic pop-up animatronic ghost decoration for Halloween and he's interested in ways that he could make a sound play at the same time that the ghost pops up from behind a styrofoam tombstone.

I'm not sure where to even start regarding this stuff, especially since the sound in question would probably be an mp3 or wav file, altho I'm sure he'd know how to rig it to activate in response to the ghost going off.

Does anyone here have any recommendations or ideas for a device that can be used to...

Why not use a mechanical device that emits a scary sound? It sounds more genuine and uncanny than a mp3 file.
You might do something with a shaped tube and a pneumatic exhaust, or some springs actuated by the same pneumatic piston.

Actually this would work well if he could change the sounds when the phone gets plugged and unplugged. Change the sound for the phone no longer charging to the scary sound, change the sound of the phone starting to charge to nothing/silence. Whenever the ghost pops up it breaks the circuit that delivers power to the phone.

>Tl;dr: gas mask advice for screen printing.

So I work in screen printing and I clean the screens most of the time and the chems my boss makes us use are super cheap and kill my lungs. I use Dhaze and ER80 and I just hate getting a lungful of it when I'm trying to stay productive.
I brought a moldex 8000 with me and it seems to help a little, but I was wondering if I need to up my game and get a better one or just keep the one I'm using.

I use a GP-5 (cheap as fug, shitty visibility), if it can handle NBC it should he able to handle paint.
I guess
needless to say I don't paint a lot.

I don't know about Dhaze, but if you're undergoing prolonged exposure to ER/80 you should be using an independent air supply. Have you even read the SDS?

Hello /diy/, this is my first post and I'm in need of assistance!
I am unsure as to how I am going to power my portable speaker set and am in need for a battery that can provide power for a small amp. Problem being, it needs to have a power socket and needs to be rechargeable. Or at least, have some sort of adapter than can allow said power cord to connect to the battery and thus provide power. Any cheap suggestions?
>Shitty MS Paint Pic related

Problem with most battery-packs is that they come without the correct output cable or charger. Any solutions? Not really wanting to spend more than $30-50 on the whole thing.

your question doesnt make sense. the pic shows a portable speaker: it contains a battery, an amplifier, and a speaker.

your ''portable'' speaker has a fucking power cord, which means its only portable as far as your extension cord.

if you wanna make it portable, one way is to muck with the insides, and find a point where you can inject, say, 5V from a power bank. this is not for noobs.
for noobs, then, you need a power inverter that generates 120 or 240V ac from a 12V battery. and you need a battery, like a gel cell used in alarm systems.

buying a real portable speaker is way cheaper than the batt + inverter combo.

I figured this was going to be a gibber project than what I thought. But thanks for the advice anyways. I myself don't really take kindly to already manufactured portable speakers because of the quality and/or life of them. But I might as well try it out. Again, thanks.

How I wrote gibber instead of bigger, I don't know. Don't quote me on that.

That's how your heater works. T'stat calls for heat and the heater turns on. To eliminate the 'full blast' effect, you are going to have to install a heater that comes on in stages.

So I have this Karcher pressure washer that's not working.
Model is K2.97.

It was in use and perfectly fine, then suddenly the motor turned off and now it won't start again

I checked the fuse in the plug, and it works fine.
I removed the outer plastic casing.

I checked the capacitor by eye. It looks ok and smells ok.
I can't hear the motor humming. I've attempted to jump start the motor by turning the fan blade with a screw driver.
For these reasons I don't think the problem is capacitor related.

Maybe a false...

Also, in the water inlet elbow for the pump there is this little switch. (Bottom right)

I have no idea what it is for.
Could it be the cause of the problem?

41 KB,
I'm thinking of getting into laser etching/cutting, but I have absolutely zero knowledge of the field. A few questions to get me started:

What am I looking for for price range (if I want to etch/engrave wood/aluminum)?
Are etching and engraving the same thing?
Are laser etchers often laser cutters as well or are these different things entirely?

Answers to these would be appreciated; anything else I should know about this would also be nice.

Laser etcher will not be a laser cutter but a laser cutter can be a laser etcher.

If you want to do it on a hobby level and you are satisfied with cutting useless stuff like cardboard and maybe thin plywood, it's not going to be that expensive (still a few $100). If you want to actually make a business out of it, be prepared to pay top dollar for something that can cut metals, I work at a laser cutting shop and most work is on stainless with a thickness of .7mm or more, for this we use a $500k machine. It will probably be cheaper today since the machine is from 2009...

Well shit. What if I just limit it to engraving metal? Would it still be capable of cutting through .5cm plywood or would I still need something heavier? I was thinking of making a small business from cutting plywood/acrylic and engraving wood/metal/acrylic.

Any (lower end/cheaper) brands you know of to be reputable so I can start looking from there?

Hey /diy/ not sure if this counts as "SFW" but...

Does anyone know decent resources for learning lockpicking? Frankly, gf and I got our car locked in a national park for several hours past closing time because a simple Masterlock was placed on the gate by a simpler security guard after a rainstorm started. I'd rather not have that happen again, especially considering the geo-political upset that may arrive in America soon.

Any literature I should research? Is it worth it to order a kit off Amazon, since it probably doesn't matter what "lists"...
