Can anyone recommend me a non destructive way to clean surface rust of items? I have some archaeological finds I want to clean. The only thing I want to do is clean off some of the rust while preserving patina and remaining traces of wood.
I looked at some detectorist sites and the methodes seem shit.
>Wire brush and wd40 >Sand blast it! >Soak it in Acid.
I don't think you understand what a patina is. But anyway if the items are valuable don't do anything except maybe clean off the dirt. If they're tools soak in white vinegar or rust off. Probably just do the former if they're "archaeological" and have some significance as it sounds like you're going to fuck them up as you still have to have some preservation plan after you clean them.
If you're just cleaning off some old arrowheads you dug out of a field because you want them to look nicer in a shadow box in your den they make non-acid rust removers intended for restoration of rusty old vintage shit. One example:
If they're more rust than iron you don't clean them at all.
>>1000955 Unless you have a crank operated welding station that's impossible. Ammo box will get red hot, fume all the paint off, and will rust after a couple of weeks. That's one of the most stupid things I've heard.
The ideal thing to start with would be a thick gas tank, but it would still require some welding unless you want to die of carbon monoxide poisoning. It is also recommended to powder coat it to prevent rust and so it doesn't looks like you've stolen it from some inbreed gypsy's... Comment too long. Click here to view the full text.
55 gallon steel drum - one lid attached, one spare lid. I could build a stove out of these with hand tools. So you get the drum, preferably one that hasn't housed anything too volatile and preferably with the paint coming off. You have four problems. 1) You want to light a fire in it outside to cook the paint and anything trapped in the pores of the steel off. We'll get back to this later though... 2) The drum will be oriented length-wise above the ground - it needs legs. Source some kind of metal stand. 3) The front opening - to feed in wood. You need...

I was thinking about how springs can be used to fly, and I realised that a bunch of cups on a spring would squeeze air out in such a way as to create thrust as a compression wave travelled through the spring, and those waves could in turn be created with sound.
I'd try and simulate this but I have no software to do that, so does /diy/ think it'd work? And would there be a better way than a one-way valve of getting the cups to not suck themselves backwards when refilling with air? Since the idea of this is to make a strange yet easily built aircraft, and... Comment too long. Click here to view the full text.
Hey /diy/ what is useful knowledge for working in a hardware store?
my local home hardware has a sales assistant position open and I'm hoping to get it so I can pay the bills, but I don't know shit about tools (no dad around to teach me). I googled training videos, but there wasn't much on offer.
>>1003074 >but I don't know shit about tools Not a problem, I've never met a hardware store employee that knew shit about anything they sold. Most of your job will probably be knowing what shit is in which aisle.
>>1003079 So there's nothing I can do to increase my likelihood of getting the job? I'd like to know at least a little, jobs are hotly contested in this small town and I want to be a convincing candidate
I have one of those undersink slide out trash bins, but you have to lift the lid yourself which is annoying.
I'd like to make some sort of rope and pulley contraption, so that when you try to slide it out, it will automatically lift the lid slightly, and then lower it back down when you slide it back in.
I thought about it and it seems like basically my problem hinges on constructing a device that has the following characteristics (refer to pic 1):
R is a weight representing the lid. Q is the device. P is the pulley that will be routed around and tied to the base of trash can.
When the rope is pulled in given direction, both Q and R will be pulled up at first (plot showing hQ and hR). It doesn't matter if R is pulled in direct proportion to Q, hence the several dashed curves, any of which would be acceptable.
After a preset threshold is met, however, Q continues going up but R remains in place.
When the rope through P is slackened back in, the events play out in reverse: First only Q is lowered without lowering R, but when threshold is reached (ie. the trash bin has almost completely slid back in) R starts lowering as well.
Just to make it clearer, second pic is an example imperfect solution: The threshold is set by putting some barrier in the path of R. After R is snagged on this barrier, it cannot move any more, so further attempts to pull along T1 results in the spring being extended.
The problem with this is that towards the end there will be quite a bit of force stored up in the spring, so the trash can will not slide out easily and snap back when released.
>>1002807 The 'magic component' is what we refer to as the 'black dot'. It's basically a micro circuit with a tiny, special purpose chip that can be loaded with very short, low quality audio recordings. The whole circuit costs pennies to buy, program, and mount, then the whole circuit is covered with a single drop of black epoxy.
You can recreate the circuit if you design it yourself, but you will never be able to produce it as cheaply as they can because they are buying bottom of the line components,... Comment too long. Click here to view the full text.
I just bought my first drill, only cost me $99 due to major clearance sale and i would like to know how /diy/ manages these batteries. The manual says to keep them charged but with Lithium Polymer this would damage them, This drill uses Lion so kinda stumped on how to handle them.

I've found the right part of a chinese bluetooth headset trashed, the left is from a philips one and the arc is from an ear muffler, the ear pads and speakers were salvaged too.
I've spent about two hours cutting, soldering and testing, I've stuffed deceased cellphone batteries behind the speaker in the Philips cup, there's a thin wire for the sound and power I had to drill the arc but mostly is pretty solid and comfy... Comment too long. Click here to view the full text.

I have a 5050 RGB LED strip behind the projector screen of my home theater. It came with an IR remote. I want to change the stock controller that came with it and replace it with an RF controller.

The controller's amperage rating is the maximum amount of current you can run through it. As long as the led strip is less than that you're fine. Don't worry. You could actually run two strings off that controller before hitting the wall.
Hey everyone, I work in a warehouse and can get free pallets that look pretty good. I'm tempted to make a butcher block style desk with those meme iron pipe legs etc.
Anyone done much like this? My main concerns are:
1. The pallet tops are pretty thin, and will likely need to be planed down to ensure smooth contact for the glue. How much do wood processing places typically charge to push through.. 8(?) pallets worth of top planks so that they are even?
2. Price I'm ok with the elbow grease involved and have most of the tools, but how much is it going to cost me in glue using those thin pallet tops? Any cheaper way to get the Iron pipe stuff? Most people who make desk legs say it cost $200-260 fml.
3. If anyone knows of a really solid somewhat heavy desk that's ideal for computer use and reasonably priced please post it. Ikea kinda stuff turns me off because of its fragile and easily destroyed nature. ATM I use an Ikea Tromso style bed with the under desk and its driving me nuts for gaming. I just want a solid ass desk thats the right height for gaming. Those 1950's style drafting desks are too much of a pain to move and wont be suitable till i own a home.
Know why /diy/ mocks pallets? They're the cheapest shittiest wood money can buy. By the time they're thrown out, they're so broken down that even picking them up can cause boards to fall off. The wood you get isn't worth the effort, and you're going to get more waste than usable wood. They're great for fires though.
Hey /diy/, hoping you can give me some ideas of how to do this. Pic related is the room (highlighted) that I need to ventilate/cool, it has no windows and the doorway goes into my kitchen which has 2 windows on the far opposite wall. Does anyone have ideas of how to cool this room? I was thinking of having a duct fan to bring air into the far end of the room, with a fan in the doorway blowing air into the kitchen, but that sounds like a really ugly solution. Any help is appreciated, cheap solutions preferred
Night shift worker here. Sleeping in the summer is terrible. My house has central air, but the upstairs, particularly my bedroom, barely feels the effects. I use a window unit in my room, but light shines through it whereas in the winter I have a complete blackout. I looked into portable units but they seem too inefficient.
What would be a good way to cover up the holes on a window air conditioner's outside cover to stop light shining in without blocking any ventilation?

Are there any cheap options for getting this thermostat on the internet?

Hey /diy/ I made a cardboard desk light. It's adjustable, and the arm and shade is held together by the fixture and the three screws. My problem is I couldn't make the flat bottom part without glueing. It needs to be a closed box so I could throw in some weight (a handful of coins atm) to prevent tipping. Any ideas? Also, I'd be glad to have your general opinion, too. (I know the cutting looks shit right now, but this is just a handmade prototype, laser cutting is expensive af here, but I already have the plans if you'd like to make one for yourself.)
I've never cross stitched before but I'd like to try it and give pic related as a gift. Instructions to make pic related is for sale as a .PDF file, but I'm wondering if I really need the instructions or if I could figure out how to make the design just using the very image attached to this post.

Alright, so I salvaged an Apple Time Capsule yesterday and I want to get it working, but I cannot find any information relating to my specific issue.
When I plug it up, the front LED does not light up at all but the ethernet port lights do (solid green). I'm thinking this is just a power supply problem, but all my searches are either talking about the front LED only or are from the Apple forums where the most common replies are just "don't work on it, just buy a new one".

>>1002406 I should mention that I don't know the actual model number, as the rubber base was removed way before I got it and the hard drive was missing. I planned on slapping an old one in anyway. It IS one of the flat models though, and not the taller one.

Hey guys, so my lcd monitor screen just recently fucked up, it takes a loooooong time for it to "light up" even though the screen is already on but very dim, it was a few minutes at the beggining now its literally hours. You can still barely see half the screen in a dark room. It also makes a constant high pitched buzzing while on that disapears when the screen lights up.
Its kinda weird, I have to wait for it to suddenly light up, then automatically turn off on its own after a few seconds and I MUST be there to light it up again as fast as possible, 4 or 5... Comment too long. Click here to view the full text.
>>1002392 its a ccfl screen right (not a led backlight one)? if so you need to get some new lamp(s) for it. its a pain in the ass to replace since you have to disassemble the panel to get to the lamps and you need to get the exact same lamp or you might need to replace the inverter too (there should be some inscriptions on the lamp or the lamp socket indicating its model) >https://en.wikipedia.org/wiki/Backlight#CCFL_backlights gl
>>1002403 oh and i forgot to add, the thing with the screen turning off on its own could indicate some bad capacitors (blown or bulged). so you might wanna check that first before tearing the panel apart. (caps are cheap and easy to replace, get the same rating [volts and farads] and line up the negative side and you should be golden)
I need to build a shed for my parents. Our old one is on a concrete slab. The shed dimensions are 10 ft wide by 9 ft long. I've done a bit of construction work before but nothing major. Do you guys have any suggestions on what I should do? Like shed plans or getting a shed kit or something
What is the best way top get rid of one's lawn? I've got no interest in maintaining a lawn, nor do I have any interest in paying someone else to do it. Is there a "proper" way to enact a scorched earth policy on my lawn or should a liberal application of ground clear and salt do the trick?

I've been ripping my hair out trying to fix this but I'm not sure how. Long story short. I cross threaded a bleeder valve on a brake. I realized it so I tried to loosen it and take it out. It won't even come out now. It just infinitly loosens or tightens. How could I get it out
Hey there /diy/! I just wanted to ask if anyone has any experience with buying, working with, living in, or building any homes made of shipping containers. I'm looking for guides or services that can help me out. Any advice is appreciated. Thanks a bunch!
