Welcome to /diy/, a place to:Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.Please keep in mind:- This is a SFW board. No fleshlights or other sex toys.- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.Helpful links:https://sites.google.com/site/diyelmo/http://www.engineeringtoolbox.com/
Some friendly suggestions for posting:- First ask Google, then ask /diy/. Your question will probably be better received if you do so.- List available resources (tools, materials, budget, time, etc.)- Try to use pictures and explain the goal, if possible- Be patient, this is a slow board; your thread will be around for days.- Share your results! /diy/ loves to see problems solved and projects completed!

How does one know go about matching stain color when you don't know what the original was? I have a desk that's (according to the website) made of acacia wood and colored "ash grey." I'd like a put together a monitor stand, but I don't want to color to be so far off that it looks stupid. Ideally, I wouldn't have to buy every stain/wood combo imaginable to trial and error it.
>>1048183>>1048185There was this one crack that was on a relatively large track that I just removed the coating on and placed a bit of solder on. This fixed all of the broken keys except for the "z" key. I ended up following the traces that were attached to the z key's switch to see where they lead to, and I did a continuity test on from the lead on the switch to some solder joints on the track, and I found out that only one of them seemed to have been damaged. I did some experimenting with a wire to find out what point on corresponded to the z key, and then I soldered in a wire to bridge the points. It's not necessarily a clean fix, but it will do.
>>1049150Good for you. Glad you got it going.
>>1049133Take a removable part of the desk (drawer?) and a piece of the wood you intend to use for the stand to a paint store. (Sherwin Williams?)They match stains as well as paint and do it daily.They'll even test their recommended stain on your board to verify how it's going to look.
>>1048996Great. But how are you sure it works? It's 12 years old. It could not work anymore!

Is there any way to make my router extremely good. Or just my internet. Also if I got a shit ton of cheap routers and hooked them all together with ethernet switches and shit would it make my WiFi better? Or is that not a thing
>>1048547Can't stress this enough. Gigabytes are going down the drain if you don't buy Monster™ cables.I've saved $1000s in internet costs since I made the switch. Soon it will have paid for itself! :)

Are these worth it in this day and age?I'm looking to buy a new one for my room, I have one mounted in a literal steel cage so security it's no problem, and I remember it worked silent and cool as fuck (good for me because I live in extremely hot weather all year round), some drunkard who """serviced""" it dropped it and it became loud as fuck, hence why I'm changing it.Don't really care about aesthetics.So here are the questions:Electricity bill wiseSound wiseDurabilityService costsI've googled it and I've found some A/C dealers websites TRASHING on window units, mostly pitting up 80 bucks units vs their 1000 bucks split units, I'm not completely sold, it's obvious they want you to buy the split unit for them to >>professionally<< install.
>>1046956My central ac was doing a horrible job of colling my apt, and electric bill was getting high. I went to lowes and bought a frigidare 5k btu unit for 120 bucks. Installed it in my room. This not only is very efficient but cools the entire room to the point where im cold. Ive started to leave my room door open and it actually keeps my living room and bed room cool too. Todays window units in my opinion are very efficient and quiet. Go for it anon.
>>1047472this. the newer ones are smaller, quieter (then the old ones) and lighter weight. for under $100 you can't really go wrong especially since you are already set up for a unit like this - you already have the hole in the wall and the cage etc. new one will probably be smaller so just fill in the gap and yer good to go.
>>1047381This man knows whats up.I all depends on how much money you want to spend. Get the window unit and save up for the split unit, the silence and aesthetics will become important to you when you see the difference, but fill the immediate need now.
>>1046956The things go for about a hundred bucks new. They'll ice box one room without too much trouble. You'll only run the thing when you're around and burning up, so it shouldn't see enough time to rack up a bill. They're not quite, but that's how it goes with a unit six feet away.
I have central heat and air but turned my air off because of too many unused rooms getting cooled off unnecessarily.I bought two window units and two of pic related a couple of years ago and haven't turned the central air on since.The three rooms I use most are adjacent and are kept at the temp I want.>set window unit temp to MAX and let the controller turn it entire unit on and off to control the temp
Anyone ever try making your own alcohol based cologne?Seen countless articles on it so I decided to give it a try. Let some cigar tobacco sit in grapeseed oil like it said then mixed the oil in with some grain alcohol and Jim Beam...and nothing really. No strong odor just some hints of the whiskey I could barely even smell on myself.Tried adding more oil and even leaving some tobacco leaves in the atomizer with the mixture and I'm just not sensing a scent there. Maybe my nose is just fucked up.Anybody else have any luck making their own colognes? Doesn't necessarily have to be alcohol based.
>>1046068Yeah most of these guides are like just let it sit for an hour but I wasn't smelling anything after that. I'm thinking about sitting the oil and tobacco mason jar in a crock pot of water for a couple hours.
>>10459831) Alcohol is a good solvent. A really good solvent.2) However, your average "thing that smells nice" isn't going to have enough aromatic compounds to make your alcohol potent enough.3) even if you feed the same solvent through multiple batches of aromatic material, you're only ever going to reach the concentration of that material. For some things (e.g. probably some herbs? maybe citrus peel? Maybe vanilla?) this might be all the aroma you want. For most things, you're going to be disappointed, which leads us to4) Distillation. http://www.heartmagic.com/EssentialDistiller.htmlWith $400, a lot of patience, a bunch of work, and a thorough web search to find the boiling points of your desired aromatic compounds, you too can crudely refine your own aromatic compounds to mix into perfumes.5) Or, y'know, buy them online, in better quality than you'll ever extract yourself:Comment too long.

>>1045983Buy a tobacco fragrance oil or essential oil. Don't try extracting the fragrance yourself, because you risk extracting the nicotine as well.
>>1046026Most commercial colognes are made up of primarily alcohol. You searched for a reaction image for this but didn't check that first?

I recently won a Siemens Simatic S7-1200 PLC with software license in a SkillsUSA competition. I'm learning to do PLC programming as part of my degree, but I'm at a loss as to what I should do with this thing. I was thinking about putting a switch panel in my car to control various functions, but this PLC needs a 24v supply and my car battery is 12v. Is there any way around that?I've also been thinking of an automated bong system, but I'm not sure if it would be viable. Any other ideas for a project I could use this in?
Siemens simatic S7-1200 is junk. You should sell it on eBay and stick with Allen Bradley.Pic is from a service call I was on recently for a Kodiak cartoner using that same plc. one of the outputs fucked up so as to that it was always outputting 24v. I didn't have Siemens software installed on my laptop at the time so I ran a wire from the input (photoeye) right to a motor relay and bypassed the plc. A week later I got a call that one of the glue head wouldn't stop firing glue. Another output fucked up and was stuck on. I readdressed the 2 outputs to spares and haven't heard back yet. tl:dr I've seen Siemens units fail more often than Allen Bradley. Don't trust that unit.
>>1048433>The addition of "step up tranformer" further confirms the retardation/bait.Nah, you have to be retarded to believe that a step-up transformer is nothing more than a transformer.
>>1048433Takes a lot more than a transformer to step down DC voltage correctly. 0/10

Is there anything more destructive than steel wool?
>>1049051>Try to drill a hole in their stainless with your drill and bit(Not the other person you're arguing with)304 is the least expensive stainless that I can get from a store nearby, so I'm used to it. It's easy to work with. Heats more than normal steel upon cutting with angle grinder, but apart from that I noticed no big differences. Drilling, cutting with fret saw, welding... all goes fine. Even threading with a normal HSS die caused with no trouble.No, I don't have any fancy drill bits. I just keep them sharp.>416416? What kind of steel is that? my local supplier does not even have it on the list of available ones (http://www.investa.pl/oferta/stal_nierdzewna_poradnik_tabela_gatunkow.html).
>>1049032>loctiteHow on EARTH do I get loctite out of my clothes without making a hole and sewing a pad over mentioned hole?It's a very itty bitty amount but it has turned black from washing.
>>1049092It's cool, I wasn't the guy he was responding to either! From when I understand 304 needs a fairly fast feed and slightly different bit geometry to work well, and in my experience that's true, though sharp bits are always a plus. You have to stay ahead of the work hardened surface. You must have stumbled across the secret and gotten lucky! 416 is a common gun barrel stainless. Works better than chrome moly in my opinion.
>>1049107try acetone, but don't get your hopes up.
>>1049145Loctite makes a wax seal of sort, I haven't read anywhere of any kind of detergent that would dissolve it.Their own suggestion is rubbing with soap and water. It didn't end well for another piece of shirt I had.
Hey /diy/,I'm an amateur lock picker. I started out when a locksmith charged me $100 for 3 minutes of work, and I'm still mad.Next week I'll be getting a pick gun. I live in a dormitory, and I'm considering offering free locksmith services because I can, and because I really want to undermine the local locksmith vultures who are getting fat off poor students who lock themselves out. I already have a rep for being a helpful guy, but I'm wondering if this is a too suspicious service to offer for free. I can't charge anything for it as that is highly illegal when I don't have a license, but I can encourage donations of pizza and beer.Also, general lock picking thread. All praise our Lordy Teacher, Bosnian Bill.
>>1049112>How did you pick it up?Bosnian Bill on Youtube for the basics. Then I was bored one day at work and found a tiny 3 pin suitcase lock. Practiced for hours with it using two paper clips. Then I gradually moved on to bigger and more complex locks.>Did you buy or make your picks?Both. OP pic is my set. I made the tiny ones in front out of rigid paper clips, but bought the Haoshi Tools one.
>>1049131Cheers bro, gonna look on ebay for a cheap set and some shit locks. Any recommendations?
>>1049136Use dx.com instead. Get the best reviewed set. Then go to your local locksmith and ask if they have any old padlocks around that you can buy for cheaps. Otherwise just go to dollar stores and buy cheap locks there.And always stay legal.
Fuck locksmiths, Im a handyman for most apartments in town and did the same because tenants would change the locks and move.
>>1049101>I really want to undermine the local locksmith vultures who are getting fat off poor students who lock themselves outSo you want to cheat hard-working skilled laborers out of their honest day's pay?Good luck with that.
Im currently in the process of fixing up my great grandparents(rip) house with the intention of moving there eventually.As Ive been cleaning it up Ive ocasionally heard small sounds in the attic/inside the walls which I can only assume to be coming from mice and or rats. There are no human food sources as the house has been abandoned for years, so I can only guess they are getting their food from the outside?I was wondering if the constant presence of humans when I move will possibly scare them off or will it just exacerbate the problem? I'll make sure to keep any potential food out of their reach to minimize their presence regardless.Im not getting a cat and have no intention of using poison or glue traps as I find it just plain cruel. I dont think live or snap traps would really fix the problem either because the population would just keep replacing itself.Ideally Im aware the best way to deal with these issues is to block any means for rodents to get in but as of now that's simply impossible as there are unused rooms(which I wont be renovating) with plenty of potential entrance holes/crevices and there's no way I would be able to close them all. But yeah, I was just wondering if human presence has the chance of scaring them off or should I just get used to live alongside them? I guess I can deal with it as long as they dont get in my way much. And if so do you have any tips to keep them from messing up my stuff? I havent found any droppings yet so maybe there's a chance they stick to the attic/walls and stay away from the actual living areas?Btw, since there's no food in the house is there anything Im missing that the house might be providing them, besides shelter?
>>1049108>I dont think live or snap traps would really fix the problem either because the population would just keep replacing itself.you can kill 20 in a night with a standard mousetrap. they aren't replacing that.
>>1049111Lol, jeez Im hoping there arent that many but still, how would they not be replaced as long as there are means for more to enter?
>>1049108Rats and mice can collect and their own food easily. Human presence doesn't bother them for the most part. If you are opposed to traps humane or otherwise and cats then your only option is to find where they keep their food hoard and nest and disturb them repeatedly. Also depending on what they are mice fit in the smallest crevices and rats simply chew their way into your home so there's no way of preventing them if you provide adequate shelter for them. Also they may a nest dug out nearby your home. Death is the best method.
>>1049119thanks for replyingIm not entirely opposed to traps as long as they are somewhat humane(live and snap traps seem alright I guess) but wouldnt it be a wasted effort as long as there are means for more to come?

>>1049023Unless your car was built prior to 1999 you don't have to worry about carbon monoxide poisoning, since modern engines are so efficient
>>1049023Put an exhaust fan in the garage. Negative pressure so it doesn't blow the gasses under the door into your house.
>>1049033I suggest you stop being a litte bitch
>>1049023>I want to be able to use my remote to start my SUV in my garage during the winter without worrying about carbon monoxide building up in the garage even with the door open.Modern cars put out only about 3% of the carbon monoxide that 1970's-era cars did. The amount is so small that it's rather difficult to kill yourself with it at all. Assisted suicide sites don't even recommend it as a method anymore.http://lostallhope.com/suicide-methods/carbon-monoxide-co-poisoning" In the past, using car exhaust fumes to commit suicide was a well known method. ... But that was before the days of emission controls on cars, which now emit much lower levels of CO than previously. Whilst it is possible to achieve death using this method, it does generally require older cars. The method is susceptible to a number of things that can go wrong, and for this reason it is no longer cited as an effective method of committing suicide, and certainly not in places like the US, UK and Australia where car emissions are more tightly controlled. "There is medical reports of suicidal people sitting in their running car, in their garage, for 45 minutes and only getting a slight headache.
>>1049041>>1049046this. there is going to be very little CO created in that time, and a simple exhaust fan will be more than enough to circulate the air. Gasses diffuse incredibly quickly, so even a small amount of airflow will do.

>>1048599Enclosure is a must, they have a small workshop in the back of their office where they make models out of kappa board and veneer. I was at a job interview with them, but I ended up being hired at a different office, then they called me and remembered me talking about 3d printing at my interview. The guy who interviewed me had gone to the same technical university as me so I'm quite sure he isn't completely technology illiterate. I'll talk to them at tuesday and explain that all 3d-printers need troubleshooting and maintenance. I think the Zortrax M200 is the one I'm going to recommend as the best choice, especially since it's available already imported here in Norway.
