electrical question.png
54 KB,

I have what seems like a really simple question but I have a hard time finding an answer just searching though the internet.

I am looking at a resistive circuit, the point of which is to generate heat.

I know that voltage = Current x Resistance

So, since I am using household voltage (120 volt nominal) and my circuit breaker says that it is rated for 15 amps per circuit with a maximal continuous load of 12 amps, does this mean that to reach the maximum allowable wattage I need a minimum of 10 ohms of resistance to run continuously?

The point of this question is to try and build an electrical furnace to melt metals up to copper so the furnace will need to get up to around 1100-1200 degrees centigrade.

Precisely what I'm not trying to do.

So am I right in my understanding?

Soup /diy/,

I'm planning on building a winter windsurfer using a snowboard and a windsurfing rig.

I just need some advice on what to use for the highlighted piece -- it needs to be strong, but not too strong that I can't drill into it to attach it to the swivel and bindings!

Also, what kind of thing would you recommend for a swivel? It needs to be strong, especially against torque (being pulled straight apart is not as much of an issue). Bonus points if it can only rotate through 180 degrees.

Oh, and an addition: it would be nice to have something slanted to attach the bindings to. The rider has to lean backwards to balance out the force of the sail, so it would be nice to have it a little bit that way by default.

Hi /diy/, I have a fein multimaster I was given by someone for free that was broken and I think that this capacitor might be the problem though Ive been looking for hours I cannot find one? Anyone have any idea what exactly this is or maybe a link to buy one? Ive found similar ones but cant find one with 3 wires coming out.

Thanks, any help is greatly appreciated.

What you have on the image is a suppression capacitor hence the 3 terminals. It looks custom or power tool grade tho.
56010000470 Should be a Toshiba or Mitsubishi made capacitor. But the only place I found that sells them is in Thailand and sells in bulk.
Fein is the type of comapny that would fix the tool if you sent it to them
Thanks guys, amazingly managed to find one in the end from a parts supplier literally listed as a Fein capacitor for just under £15 with the P+P so not too bad, now just to see if it works when the part comes lol.

Hey /diy/, valentins day is coming up, are you making any gifts?
My girl just got into Magic: The Gathering and wants to put together her own deck, so I figured I'd make her a deckbox out of wood like pic related and help her put together her first deck as her present.

I'm gonna get some 1/8 in craft wood, dovetail each edge, stain them and glue them together, inner dimensiosn around 3.75*2.75*1.75 so it can accomodate sleeves and then woodburn a heart or some shit to the top/side (I have experience woodburning).

...a flashing LED. You can literally get LED's that flash all on their without any external circuitry, other than the resistor.

now am thinking about 2 transistors circuit as far i know it should have stable frequency or i am wrong?
It'll be stable enough that you'd need an oscilloscope to measure any jitter, sure.

What type of aerial connection is this?

8 replies and 1 images submitted. Click here to view.
The Belling-Lee connector or IEC 61169-2 radio-frequency coaxial connector of type 9,52, known colloquially in countries where it is used as a TV antenna connector, as a PAL antenna connector or simply as a TV aerial plug
That would be a coaxial...aerial connector.

As far as I'm aware they don't have any specific name to them. It's just an aerial connector.
Ah ok sweet cheers, just trying to find out what converter plug I'd need as I have to add more length for the cable to reach the tv

Hey /diy/

I have a question for u, how to cut open a porpane or butane gas canister if I have like 0 tools, but I can ask for some, what do u recomend?

>A tank like picrelated or smaller
29 replies and 8 images submitted. Click here to view.
>if I have like 0 tools

Wait for it to rust itself open.
Vent it safely first. Those thin sheet metal canisters aren't useful for much.

I suggest throwing the canister away, learning about tools, and gradually accumulating a potentially useful mix of tools over time. Used is fine, I get all sorts of good gear at yard sales.
Go to HF and buy an angle grinder. Also, you may kill yourself if you don't empty the tank properly and the latent propane explodes when it's exposed to a shower of sparks.

meal worm farm.jpg
94 KB,
I want to start a mealworm farm for making edible mealworms.

Has anyone else tried this? Is it financially and temporally feasible to grow mealworms as a food source?

Edible by whom?

Also: https://news.stanford.edu/pr/2015/pr-worms-digest-plastics-092915.html

Mealworms are easy. Get a stock of them plastic tubs and feed them.

The biggest problem I had with them is harvesting them for my chickens. Theres no real easy way to do this. So i switched over to BSF since they harvested themselves for me
Edible by me and maybe other people. I am interested in breeding them for food as they have a good protein profile and are nutritious.

What is BSF?
it's a type of fly larvae.
To feed chicken.

Hello. My amplifier started giving out on both exits (a and b) noise. cinder flame noise and windy noise. I thought it might be transformer since now it was very hot. Also when i took of top cap i smelled smokey smell. What could it be
It's sanyo dcx 8000k.
It worked like a wonder week and a half and now this.
Need ideas because i think i checked everything.

Thank you

1st picture was bottom side of transformer
this pic is top side of transformer
also where can i buy transofmers
Might not necessarily be the transformer that's failing, if there's a smoothing capacitor that's dried out or is failing, that can cause the tranny to overheat. I'd look at the whole system rather than just assume it's the tranny.

http://www.farnell.com/ is a useful site for picking out parts. Even if you buy somewhere else, farnell has a brilliant parts list system that you can then take an item number from and go elsewhere.

Heya! I need advice on how I can fix the R button of my 3DS. I was playing MonHun and suddenly stopped working; guess it was some dirt so I blowed it a bit, and now fuctions halfway -idk if that is expressed right, english isn't my primary language-.
Thanks in advance!
3 replies and 2 images submitted. Click here to view.
Pc-air duster that shit. Otherwise take it apart carefully and clean it.
If blowing it out doesn't work (clearing a physical obstruction) the button itself is likely shot.

They're tiny-ass little microswitches. They can't really be cleaned or serviced, and if you've got the case open far enough to get them out it's stupid to not just replace them entirely.

They're replaceable fairly easily if you're careful.

238 KB,
This is my first thread here and I'm telling beforehand I don't knopw if this break any rules. I want to discuss the making of "vape juice", the liquid that is put into electronic pipes or however they are called.
I don't know if that's illegal on some places but I'm not putting tobacco or anything, just glycerine and some flavor.
I don't want to end up banned because I really don't know if this breaks any rule, but vaping without tobacco seems just something fun to do that doesn't involve drugs.

Thing is, I haven't vaped before so I won't know if I have done it correctly.
I'm going to buy vegetal glycerine, needed as base for the mix, because it's cheap and it produces a lot of vapor. The thing is I saw that "flavor" are just concentrated liquids.
My question is: How do I make my own flavor? Is that even possible? Example: I have some vanilla and I want to use it to give flavor to the juice. I'm searching on the topic but I can't find that info. Anyone?
Dunno how safe making your own flavors would be.
You can buy flavorings pretty cheap.
Here's 8mL vanilla for $1.87
Thanks. I thought they could be way more expensive. I wanted to buy the vegetal glycerine at a farmacy and I can't use the Internet to buy stuff, although I could just ask some friend.
You guys can discuss your mixes and stuff vape related here, I'm very interested because I get very relaxed inhaling vapor and buying one of these seems really comfy.
