What do I do guys. I got thermal paste all over the top of my cpu when I installed my heat sink. Was I supposed to leave something on top of the cpu? Did I ruin my computer?

sup /diy/
I need some help with a projection screen I got for free from Craigslist to use as a sun shade on my balcony. I set it up and ran into a problem. I can't retract it easily. It seems that the ratchet/pawl mech only wants to retract a few inches at a time, and I find myself in a 1 step forward, 2 steps back battle.

My question: Can I somehow set this thing up so that the spring is always in "retract" mode? I'd anchor it at the bottom and when I need it to go up just remove it from said anchor.

One end is a round pin that spins,...

These are quality, expensive screens - fkn waste as sunblinds. Apart from that, are you trying to operate at an angle? vertical only operation should work (better..). then hang ennd over something.. dunno how you setup at the moment, but they definitely designed for vertical use.

However it is mounted the flat key should be in the vertical || position.

At least thats what its supposed to do.
It stopped working a few weeks ago.
Pulls water from my (((distillation machine))) and into my kitchen.

How do I debug this?
Should i try to open it and look inside?
Maybe it has a clogged filter inside?

Its nailed to the wall, so it's been completely still, so damage from random fall is impossible.

Power in the house has been dodgy. I live in god forsaken Puerto Rico and we have short but numerous outtages. A number of appliances have stopped working because of this presumably.

Could it...

Plug it into a fused outlet and put a meter on it. If it's not obvious, open it up, plug it back in, and trace the power from the source to the destination. If all that seems to work, then you're fucked bc it's not electrical lol
>>
Outages don't often kill equipment ( hard disks can be the exception). Most equipment failures occur because of the voltage spike when the power comes back on.

If you get a power failure, turn off everything except the lights in the room you are in. turn those on so you know when power has returned.

A lot of electrical kit has inbuilt fuses (sometimes small, soldered in place and hard to find). Give us derails on the pump and maybe we can tell you.

Could also be the impeller seizing due to contaminant buildup (assuming its an impeller one not a diaphragm)...

The polyfuse might have died (the one that cuts the pump if they overheat) or it might be time to replace bits - see the bottom of the manual.

They just started doing this within the last 3 days.

They are most definitely not over watered.

Continuing from last thread about soldering a phone power button...

Finally got some conductive glue in the mail. The syringe was absolute garbage but I made do. Overall I think it turned out as expected, it should work....just waiting for it to completely dry.

Hopefully it's not toxic, my hands were starting to look like the tin man's.

They are extremely old but in good shape and sharp.

The problem is the edges. They seem to have a slight curve to them.

Can this be sharpened out or do I have to just deal with it.

Thanks

Yeah, it can. I've had to refinish all of mine at some point. You can easily fix them with a file. I'd recommend sticking it in a table vice if you have one.
>>
Sharpen it.But you'll have take off more material to fix it. A bench grinder or a belt sander with an old 120 belt could help the process. I mean you have like 3-7inches of material there. Just keep sharpening it til there's nothing left
>>
>>1014754
Just to be a pedantic shit, you can't really sharpen it all the way down like >>1014776 said, they're not hardened for their entire length, but you're looking at maybe grinding off 1/16". I assume you know a little about hardening, and that if you just stick them up against a grinding wheel or belt you will overheat them and ruin the temper? If you don't know this, then take your time, grind for a few seconds (maybe 5?), then dunk it in cold water...

Seal_C.jpg
343 KB,
I need to replace the seals on the end of a hydraulic piston ( from a 4 ton porta pack type bending kit ). I can't find a parts list or manual for this kit. They seem to be a standard size and type - I.D. 3/4" O.D. 1 1/8" Vee type. I don't know what material to look for or if I should just buy a 'replacement set'. They seem to be 3 different plastics capped by a special steel washer and a bronze ring.

any suggestions on what to look for or where to buy seals (i.e. ebay/hercules/? )?

what torque do i need to put on the piston nut?

did you remember the way you put them together? (just making sure)
also there are seal manufacturers that stock standard sizes.

I live in a very dry desert and there are TONS of water bugs outside my house at night and they manage to get inside. I also have huge weeds despite there not being any substantial plantlife in the area.

I just found out that my neighbor is flooding her yard with water on a regular basis. I have no idea why. I think that's what is causing the weeds. Could it be causing the water bugs, too?

The weeds are probably growing naturally.

Water doesn't flow laterally unless it hits a surface that restricts flow enough to send it laterally.

Huh, wonder why they're growing in my yard and nobody else's. Literally my yard is the greenest place in the desert (except for the park down the street with a lawn).

Firtst time /diy/ post

So I made a smartphone projector out of a shoebox and a convex lens. I bet you all know that the image would flip, even if I prevented the video from rotating upright.

Is there an app that would allow me to play flipped videos or images? Or should I redo my box with mirrors?

VLC could do it on a computer, the feature or interface might have been trimmed out of the android version, but you could probably get it back with the command line and then making a customer launch/shortcut/something for convenience.

Newfag here, I hear that you can make lye, soap and biodiesel out of ash. Does that include the leftover ash from my coal-barbequing? And in that case, can I use this coffeemachine to make the lye by using ash instead of coffee powder?

>>1014237
Your coal Bbq ash has significant amounts of dirt filler. Sift it through grains of mesh to get it out. Google potash
>>
>>1014240
So is potash is the thing in the ashes that give you lye from filtering boiled water through it? Sorry, I'm basicly entirely unfamiliar with the composition of these things, and not very good at chemistry, either. All I know is that the ashes would need to be burned thoroughly.

Also, the pot in the coffeemachine is made from glass in case that wasn't obvious, but is plastic an OK container as well?
>>
>>1014248
>>1014237
Wood ash has potassium in it (quite a lot of it). When you mix potassium with water it makes potassium hydroxide, which is alkaline. That's your lye. Mix lye with a fat and you get soap.
