Sup /diy/, I have pic related in my backyard used to store waste oil. My experience has been these always rust out the bottom well before they're full(currently has 80L in it). It's already elevated off the ground so it's not going to rust from being in the elements but rather from the water accumulated inside.
So I had the idea of periodically drying the contents by sticking it on a gas burner and heating it up to 150 C for an hour or so. My question is if this is going to bite me in the ass later on. First problem is the paint on the base is going to... Comment too long. Click here to view the full text.
My bike started cracking around the seat tube since the top part of the tube is slightly smaller in diameter than the rest of the tube, which means that only a small part of it makes contact with the seatpost.
I've been trying to look around for people to weld it but haven't found anyone that I trust with it.
Should I just fix it myself? my idea is to cut the portion of the seat tube that is a smaller diameter and insert a new piece of seat tube in which I can then bolt or rivet in.
>>936640 Make sure they strip the paint and clean the metal good. A tig welder should be able to tmdo that for like 50 or 75 to 100 bucks depending on how good they are. They should also be able to level the weld off so you never even knew it was there.
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.
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.
I'm getting an amazon shopping list flushed out with a few things I want, but I'm not sure what i should do about the last item, paracord.
I want something sturdy, that can hold my body weight, is flexible, and won't make noise when attached to something like chain does and more importantly is small. So I came to the conclusion that paracord is what i'm looking for.
I only really need about 25 feet of it for everything I want, but I figure ill buy 10$ worth whether its 50 or 100 feet as I'm sure at some point in the future I will have... Comment too long. Click here to view the full text.
>>933564 A single paracord not actually rated for human safety. You will shock load it to 1500 pounds easily and break it and fall to your death. Get climbing rope if you're climbing. It's a commodity and prices down as far as it can go.
>>933591 Don't worry, like I said, not using it for life and death, what I want it for is something sturdier than twine that's able to hold weight.
the two things I want it for are this
1) hold a rotary tool by the I beam in the basement so I i get the least amount of twist in the flex cable. and 2) using it to hold onto and exercise with my own body weight. think of how a gymnast rings, but instead of suspending my whole body, I use them as close to the ground as I can in the push up position.

Literally anything. The reason nobody makes "vintage" transistors is because they are essentially 100% substitutable with modern devices, and unless the circuit has some retarded design, it will work better or be more reliable with modern devices. 2N3904 should work perfectly fine and cost pennies a piece in bulk.
Sink clogged, both sides have water backup in them. How do I fix this so I can do my dishes tonight? I have a shit load of dirty dishes. Any advice or expeience would be a great help. I was just going to grab a bucket, take shit apart and scrape it out with a wire hanger, but I think this job might require a little more finesse.
It doesnt even have to be a permanent fix, the sink has always been a problem. And it should be my lanlords problem.
>>936009 Plunging just pumps water into the other side. The piping runs down into the basment and just flows off into a hole in the cast iron sewage pipes. This a 100yr old historic peice of shit apartment so everything in here is just janky as hell. Pic related
Yeah, that's an IEC C13/C14 connector (usually just IEC). You'll sometimes hear them called "kettle leads", which is actually something different. Easy to pick up in any kind of electricals or hardware shop.
No idea what that audio DC connector is for, though. Speaker power, I assume.
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.
>>936596 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.
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.
i have question and hope you guys can help me. reently i took apart a couple of wall mounted intercom devices. in these devices i found a speaker and an amplifier. so i thought maybe i can use these parts to make a small portable speaker.
The speakers i found both work. but i have no idea how to wire the amp in there and the best way to supply the power.
the amp model is a TDA1519B. i found the datasheet for it here: http://www.nxp.com/documents/data_sheet/TDA1519_CNV.pdf
my knoweledge of this stuff isn't that high so i can't really figure it out on my own. i was looking at page 8 because it contains a diagram of how to wire it and for so far i think i figured out some of the connections.
PIN 4 and 6 will connect to the + side of the 2 speakers - but where does the - go? is that wired to the - of the battery or to the ground (and how would i achieve this)
PIN 1 and 9 are non inverting inputs. so i assume if i want stereo sound i put the left and right input on these 2 pins. (do i connect the - of the speakers to the - side of a 3.5 mm stereo cable?)
PIN 7 is the supply voltage so this is the place where the power goes in. the document says this should be around 14.4 V with 40 mA. but except for pin 4 and 5 there is no output so again what do i do what the - side.
so this is kinda what i figured out from it but this isn't my field. i know how to solder stuff but i don't really know all this stuff so maybe someone can make a simple drawing of the full schematic? if someone would that would make me very happy.
>>936879 When you ask that kind of questions, I'm pretty skeptical that advice given here will be enough.
Anyway, the symbols on the other ends of the speakers mark ground. There are other grounded things as well and you connect them all together and to your power supply's negative wire. You also connect the ground of your input jack to the same point, as well as the IC's pins 2 and 5. Use short wires and connect the input jack's ground to IC's pin 2 with a separate wire. 40mA is the current... Comment too long. Click here to view the full text.
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?

>>936346 Yep. not 100% sure with bamboo, but wood bends a lot easier with heat and moisture, green will help but may still need to heat bend. Bend it farther than it needs to be, it WILL try to straighten out some. So if you bend it into a 180 degree curve, it will straighten out to a 140 degree or 90 degree or something.
Also, it would be much easier to setup the board runners along the side and stake them to the ground, then bend and nail the bamboo hoops in place on the inside of the boards. It doesn't matter... Comment too long. Click here to view the full text.
