When I first installed this '62 fender AVRI neck pickup in my hss telecaster, the neck and middle were out of phase, so I switched the black and white wires (cloth in photo) and the phase was fine. The problem I have now is that the notch position (neck/mid) isn't noise cancelling like I need it to be. In addition, when I touch the neck pickup, there is a really loud buzz sound. Is this because of how 62 teles were wired/polarity difference? Is there a grounding issue? How can I make it behave like the stock neck pickup?

You lost noise canceling because you brought the neck and middle into the same phase.

Noise canceling works by having each pickup, 180 degrees phase shifted from the other. How do you expect to cancel out hum and noise with no phase shift between the pickups?
Maybe phase is the wrong term? I mean like a strat's neck and middle pickup having reverse polarity so they cancel each other out removing hum when combined. At first when I combined neck and mid they had a very trebly tiny sound a la peter green's out of phase

I'm confused on what you want.

To get noise canceling, the pickups have to be opposite polarity from one another (180 degree phase shift). Configured this way, anything in common will be canceled out, including 60 Hz line frequency buzzing. Overall output is usually lower when you have the pickups wired this way, and the tone is altered.

The only other way to get noise canceling is to use stacked humbuckers (they look like single coils) in place of your single coils, put a big loop pickup in the...

what is the minimum thickness of concrete that i can pour?

i want to make a lattice with .75"x.75"x.75"

what kind of concrete would i need?
20 replies and 2 images submitted. Click here to view.
Depends on the performance you need. Concrete is very weak in tension, especially if the aggregate is almost as large as the thickness. Cement and sand without large aggregate should hold together in a .75" cross section, especially if you mix in reinforcing fibers.

However, that may not be the best material to use. Plaster is more suited to detailed casts. Fired ceramic is stronger. Epoxy resin is tougher. What do you need it for?
>Cement and sand without large aggregate should hold together in a .75" cross section, especially if you mix in reinforcing fibers.

so a mix that is as fine as possible (concrete and sand) would work best, here?

and what serves as reinforcing fiber?

i make the negative out of foam modules, and then slide them into a 2" wood cube box. i pour the concrete (here, i'm not sure if the concrete will fill all the cracks)

at the end, i use acetone and a pick to dissolve the foam (eps).

Just how entitled are you? You aren't paying him a dime.Yeah, he's not busting his ass all day, so fucking what?
And from what I get, he experiments a lot beforehand, so that he shows (pretty much) finished product and not the first prototype.
Who gives a shit? It's a youtube channel, he has no obligation to do anything, he could release one video a year and it be nothing but paid promotions. He's trying to make money to live off of, if you don't like it, don't watch.
I unsubscribed from him back when he still only had a few hundred thousand subscribers and rarely, if ever, showed his face, the good old days. Most of his videos are things that have been done a thousand times before, with hundreds of videos already on you tube by people much more knowledgeable. I would agree that he's grown extremely lazy in his fame. But, he's basically figured out how to make money by creating videos for the children of autists. Which is brilliant, btw.

I want to make myself a chainmail belt but I have a few questions.
What kind of chain should I use so that they are strong enough to hold up to regular use but also rust resistant enough to not make a mess

How do I close the chain links so there's nothing that will snag on or scratch clothes or skin

What chain pattern should I use

Where's a good place to get chain?

Also general chainmail discussion thread
25 replies and 10 images submitted. Click here to view.
Hey there a lot of videos on on different weaves that you can use for your application. Since this belt will stretch a bit as you move, you don't want the links popping open so you would have to solder closed each and every link. A work around for that would be to add in a few rows of rubber o- rings instead of metal jump rings. Also its really easy to make jump rings so I would make them myself.
To be honest I'm really new at making chainmail so I don't know what jump rings are and I don't have the tools to solder the rings.

Know any possible work arounds or is the solder tool a must?
But why?

So this is an odd topic, but I've sunk enough time into the last 3 days troubleshooting my poor graphics card hoping it would be a driver issue, and learned enough on the software side to almost certainly deduce that it must be a physical problem.

So when people talk about a graphics card getting old and weathered, what parts of a GPU actually degrade? and how would you detect this kind of damage?

What about how a card sits within the case itself, are there any specific parts that need to be padded so as not to touch other metals? or is that all for the sake...

Memory chips can degrade over time. Long term overheating can cause the transistors in the GPU chip and peripheral IC's to break down I guess?

Biggest and most likely failure points are any electrolytic capacitors. Is the OP picture related or just a random google picture?

Don't touch it with a soldering iron unless you absolutely have to - honestly it's actually better to heat the whole board in an oven than to prod around with a soldering iron unless you really know exactly what you are looking for. Even then most surface mount in very sketchy...

Thats just a google image, this however is the real thing.

I thought at first maybe some thermal paste had gotten elsewhere on the card and could be harmful, but ive given it several pretty thorough cleanings with alcohol. Still cant get rid of what you see here though.
>GTX 580M
it could be any number of things, but since this is a rather new graphics card it's highly unlikely to be solder problems on the BGA

those tantalum capacitors though are prone to bust every now and then

I'm going all out and repurposing an old CRT monitor by making it look fresh and new. I plan on using spray paints and giving it the works.
I know enough about disassembling it and taking the precautions with leftover electricity and whatnot. But I've hit some snaffus and need some questions answered.

1.) Anyone have any idea what plastic monitors this old are made out of?

2.) When taking apart, I discovered that the plastic was extremely brittle, especially on the inside with some of the tabs holding the frame to the back of the monitor.

Also, I have pretty bad luck with spray painting.
I swear I do it right. I know to apply multiple thin coats between however many minutes the can tells me to apply them.
But unless I live in a shitty climate that's always humid, it's like the paint never dries, or it's never permanent.
I guess it's because I never sanded and primed before, but I guess that makes all the difference between something being extremely delicate to handle to something withstanding scratching without revealing the color underneath.
Few thoughts:

-i cant think of many good suggestions for re-inforcing the plastic from the inside. plastidip is a cute idea but I don't think its really going to help, short of "if something cracks it might stay in place because its effectively got a huge layer of glue on the inside holding things in place".

I would just be as careful as possible and use superglue to put broken bits back together, or the superglue/baking soda trick. or a 2 part epoxy. youll never see it once sanded and painted...

I've watched videos on how to paint. A lot of them use air brush guns which is a whole tier above what I have at my disposal.
Though I am impatient, I can understand the timing between multiple thin coats. My biggest thing is the sanding which is tedious. I'm doing an all-around rub with 220 grit, and it gives an almost brushed metal-like texture in the light. Do I continue to sand over that with even higher grit, or if I do multiple primer coats and multiple color coats (and a top coat), will that texture show through??

I got a small working security camera which i cant get to work. Pic related. In the old situation it was powered with a wall adapter and connected to a security monitor using a weird coaxial cable that had "75 Ohm" on it. I tried putting a normal coaxial plug on it but it didnt do squat when i plugged the camera in my television.

Does anybody know how to get this thing to work?

Protip: Look into what delivery drivers use. The pizza guy basically has a fabric box with insulation and mylar lining and it keeps a pizza warm for 20+ minutes.

Want to further improve that design? Add something warm to the box and keep it sealed, like a brick or pizza stone warmed up in the oven.

Insulation isn't that hard to do. The benefits of the pizza bag is that you can store it easily and it is food safe.

Also less than $20 gets you a little 12 volt heating blanket for the car. Dont like being a buyfag advise giver, I found mine in the trash with a busted plug, low wattage heating coil is useful.
Just use a cooler or insulated lunchbox and wrap the food in a couple of towels. If you want to be really fancy you need some sort of heat pack like a couple of chemical hand warmers next to the food.

Hello there /diy/, I'm in need of your help.

Long story short, where I live, you can backfeed electric power into the local power grid to lower your power bill. Being a NEET and bicycle enthusiast as I am, I've been toying for a while the idea of building a bicycle-based power generator, then feed said generated energy into the grid.

Fuck, that picture makes my fat leg skin hurt
Pro athletes can sustain about 600 watts on extended climbs.

Untrained individuals will struggle to sustain 250w

Power is billed in kwh. 1kw of power useage over an hour. The US average is 13 cents per kwh. So if you were to cycle for 4hours at 250watts you would generate 1kwh of power.

Dont forget losses from the drivetrain, generator and converter which will all add up to at least 20%loss through heat.

More than 4 hours of work for about 20 cents of return.
