>>964449 Not a good idea. Generally speaking, one should de-rate capacitors based on the nominal rating, i.e. use a >24V nominal cap if you expect a 24V input. Trying to use a cap based on its surge voltage would be terrible for the health of the capacitor, assuming it didn't blow up on you.
>>964449 Also, according to this guide, "Rated surge voltage is the maximum DC overvoltage to which the capacitor may be subjected at 25 ºC for short periods not exceeding approximately 30 s at infrequent intervals of not less than 5 min."
just finished my first pic related and I'm kinda able to crack it but >how the fuck do I drop strands while mantaining consistent oval bent? on every spot where I dropped a strand the whipbents really sharp and I think it makes it harder to crack
>>964364 Is the fall just the sheath part of paracord? That'd be too light for my liking, i usually double mine (tape one end of paracord sheath to a thick needle and push it inside through itself in the middle). Also lose the tape and put some turk's heads there.
Did you roll it? If yes - did it help the strand drops?
>insulting tape instead of turk's heads oh jesus i feel for you bro
my first hundred attempts ended in everything's fucked and i don't understand why aaaaa
it doesn't help that most 'tutorials' show how to tie one particular pattern but don't explain WHY there are patterns, and the youtube results are a bloke mumbling over a ball of black cord in a darkened room in 240p.
Is there some sort of jig or something that lets me sharpen these style drill bits with accuracy?
PS I sharpen ordinary bits by hand with a bench grinder but that's pretty easy. These require more finesse but the only jig I know of that can sharpen Brad points is some $$$$ Darex sharpener that no hobbyist would buy.
Buy an auger bit file and do it by hand. I clamp mine in a wood vise If you are too lazy to by the correct file, then at least get one with safe edges. Will only take a few strokes of the file to make it sharp.
So I'm looking to make my own backpack. Tired of the available products out there, nothing quite fits my needs and I think I can do better just making my own. I think I have all of the tools and materials I would need.
I'm thinking of something sort of like pic related. Large gussets and compression straps so that it can expand or contract as needed, because my gear varies quite a bit depending on season and what I'm doing for the trip.
My questions is in regards to a frame. I have the materials and tools to make an aluminum frame, but I really don't want a large bulky frame, and I'd prefer it to be internal. I already have a really nice external frame pack for big hikes. This pack will be for carrying gear on shorter excursions, 1-3 days we'll say.
Thus we come to my question. Anyone have experience making an internal frame? As I said, I could do aluminum, but I feel like I'd have to pad it heavily to get it to be comfortable, and that's just added weight/bulk that I don't really need. I considered thin plywood, laminating plastic lids from big Rubbermaids and cutting to shape....nothing quite sounds like what I'd need. So I'm looking for some brainstorming/ideas.
For reference, this is what I've been using lately. the removable pouches are quite nice, but the picture is misleading as the pack doesn't hold its shape at all unless it is packed full of clothes or something else soft. Anything hard or just empty space will make it collapse or deform and I'm tired of it. Hence why I'm interested in making something with a light frame.
>>963024 why can't you find an el-cheapo goodwill type store, that will have a hiking backpack with a frame already, and just build around that? you can chop it up if its too big too, just need a hacksaw.
besides that, I'd say fiberglass rods, and epoxy them together for your frame shape, keeps the weight down and bulkyness.
idk what you mean by an internal frame tho. if you where talking about something like two pieces of flat aluminum stock, running up an down, boy are you in luck.

Hey /diy/, I just moved back home to save money and relocate to a better area but I cannot take the noise from my large family after living alone for so long. I've decided I'm going to build a small shed and throw a mattress in there, which is great because the property is huge. 10x12 is what im planning on. I'm not too handy but I have built a shed before so I'm fairly confident this will be easy peasy.
I have a couple questions.

Because mathworks.com is a desert and a looks like the admin are a bunch of sissies, somebody has or at least tried the kkt (karush-kuhn-trucker) algorithm for optimize in matlab? Would be very thankful with your answers.
Plus, is better and flawless the language of Python in contrast with Matlab? Which of boths is usefull now day?
>>968707 I think Matlab is dogshit, but that's not because of a lack of power or features, just because it looks god awful and the syntax is fucking assbackwards and has no consistency.
But it's incredibly powerful, and well supported. And seems to be fairly fast.
I dont think you can compare something like Matlab to Python, they're completely different. I much prefer Python as a language for its syntax, but Matlab just has the tools you need without having to go out and find a Python library for it.
There is an academic text named "Semismooth Karush-Kuhn-Tucker Equations and Convergence Analysis of Newton and Quasi-Newton Methods for Solving these Equations ", Google it, If Matlab were less shit in comparison with new currently programming languages maybe a bookstore for this algorithm can be easily found on internet, try it.
My uni course has added Matlab as standard for the first time this year, it's pretty neat but I'm yet to see the full use of it really only being a first year. Interested to see how we use it in the next 5 years though and it's definitely preferable to the stuff I used in high school!
Ok /diy/, i have 2.5-3g of pure honey feom the keeper and today my buddies mom let me borrow a blue glass 5g jug. I don't have an vaper lock, which is why I'm making the thread, but I've looked over a few /diy/ lock on google. So my question is this, what kind of lock would /diy/ recommend a first time wine maker make?
>>968215 I would recommend going to a brewing store and paying the 5 dollars for a purpose-built one. It'll be essentially like your picture, but will cost you less and you'll be certain that the materials are food-grade.
my goal is to get these (0g) in my ear tonight. my ears are not pierced. i have no patience and no money to spend on other methods.
i am thinking about piercing with a safety pin, tapering with a toothpick, a sharpened chopstick, and eventually a pen, then fit the earring in. all the tapers will be wrapped in teflon tape and lubed.
any advice? how traumatic will this be for my ears, anybody have any other ideas on how i can do this easier?
i am dead set on getting it done tonight, please dont try to convince me otherwise.
>>967610 >i am thinking about piercing with a safety pin, tapering with a toothpick, a sharpened chopstick, and eventually a pen Holy shit op, you are going to fucking destroy your ear and most likely get a massive infection.
>>966101 Yeah, that was my first thought. I actually have some recipes for some organic lip balm, soap, body cream, ect.. Going to make some awesome labels and put it in a nice bottle and sale it that way.
>>965858 Either get some tiles that absorb and conduct heat poorly or cover the tiles with something that conducts heat poorly, like a rubber mat. As simple as that. Your other options involve using energy to heat them.
Does anybody here know anything about gunsmithing or have a career as a gunsmith? I'm wondering about the profession and just thought I'd come to here to ask you. What sort of experiences/credentials would one need? What are the most enjoyable parts and most tedious parts of your job? What is your average workday like? Pic unrelated; thank you in advance for your answers.
Best regards, O.P.
P.S: I originally asked this in /k/ but figured /DIY/ might know a bit about gunsmithing considering they know a lot about tools, doing projects... Comment too long. Click here to view the full text.
It's a profession full of hacks as well as super craftsmen. Customer wise full of wack jobs and serious user/collectors. If you are a top machinist and know your shit inside out you will attract the serious clientele and do OK. If you buy a lathe and mill and take a 2 week course you are going to be up against a pile of shitty competition competing for shitty clients.
If you really like guns and really like precision machining, and are willing to put in a few years to learn and gain experience, you could do OK. It's not easy or big money though, even if you're... Comment too long. Click here to view the full text.
>>969025 If you're good at the stocking side there is work in muzzle loaders, meaning flintlocks. It'll take years of a few rifles a year to build a name and customer base to the point you can do it for a living, but the legalities aren't nearly as involved. And you need to be very good. The whack job customers, like on /k/, will make you shake your head in disbelief if you go with modern firearms.
Yesterday I asked my landlord to unlock my basement to investigate an offensive odor and we discovered that it was a mire of stinking human feces, toilet paper, etc. At least two inches deep in a 12x12 area.
Haven't snaked the line yet, but I have a question:
Usually tubs and toilets will have problems draining when the line is clogged. But I didn't notice anything unusual about the plumbing. Everything drains quick and smooth. Can this clue help narrow down the source of the blockage so we can get to the bottom of this quicker?

>>967880 >asked my landlady to unlock my basement never move into a house that has a condition of "dont go into this room anon" because people fucking store shit in there. its either illegal and they want to keep it not at their house or they're being cheap niggers who dont want to pay for storage. and they're risking literally forcing you to live over a pit of shit in your case or a major fire hazard by not letting you enter sections of your own house.
Hahahah that was exactly the case in this situation. There was a ton of stuff down there. I actually previously asked about getting the key for the purpose of storing my own things and was told "it's small, there's no room to store things". Three hours of him hauling shit-covered belongings into my yard the cleanup work began. Fun bonus: one of the objects was a full 20lb bag of dog food to feed the "rat infestation from the neighbors sorry it's incurable".
