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/ (archived)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!

Does anyone do flint-knapping here? How expensive is it to get into things? I'd like to make some Acheulean or early, Oldowan-type tools for use in a photoshoot.
>>2872764it's literally freeyou can find flint nodes in most rivers, streams or beaches. they're the fist-sized white oval/round looking rocks but they can also be found in other colours as in picrel. You won't be able to knap most of sedimentary stone (shale, limestone, sandstone) because it's so brittle and you won't be able to finely knap most common igneous stone (granite) because it's too hard. the most simple stone tools are hand axes which are just flint/obsidian/chert nodes that have one or two pieces chipped off to make a single blade/edge. You can practice making these with a hammer stone (an oval stone made of quartz/sandstone/limestone) to chip off two sides of a tool stone. the removed shards can be further refined into microblades. this is basically how oldowan tools were made; a single hand sized node with a couple edges chipped off using a hammer stone.soft hammers can either be made of deer horn or hardwood like oat. these deliver better results but are much harder to useAcheulean hand axes are made from a "core" extracted from a node that should be perhaps twice the size of the intended tool. You use a stone hammer to remove both sides of it and can either use a stone or bone hammer to remove smaller and smaller chips to finish the blade.
>>2873031Its called jeans m8
>>2872764Please be aware that flint knapping is illegal in the UK and many other countries and states if you create a blade longer than 3 inches
>tfw almost no flint in my country >accessible obsidian is long gone The autochthons used ground-stone tools rather than knapped I think there are some volcanic islands full of obsidian but you would need a boat and some are illegal to land on (pest-free wildlife reserves)

I have a cast iron boiler from 1975 which still produces heat but has had multiple problems in the last few years (mostly with components other than the boiler itself). I was quoted 3k to change the pump, valves, expansion tank, and a few other components, and 9k to change the whole boiler plus everything else that goes with it. Should I just bite the bullet and replace the whole thing?
Gas furnaces only cost $2500 delivered to your door ready to install from a wholesaler. Fuck HVAC niggers. Its not hard. Just Do It YOUR SELF.
>>2873528Supplyhouse.com get a WM CG-5 or whatever the current equivalent is and DIY.
>>2873557$2500? Where TF are you ordering from You can get a 96% efficient gas furnace from alpinehomeair for under $1000
>>2873528watch some vids and find a boiler that you feel is good for your house, consider your square footage to BTU output so you size your system correctly. piping a boiler isnt that difficult if you take your time and read the installation manual. Google and youtube videos are your friend.Are you on gas or oil? If youre on gas I would atleast leave the gas hookup to an HVAC company, that way if something fucks up its on them. In terms of what you got quotes, 3k is absurdly expensive, it sounds like an expansion tank, a relief valve and a circulator pump. 3k is gnarly.
>>2873557>>2873599>>2873770There's electrical, plumbing, and gas work involved with switching a boiler, and I don't have enough experience with any of those. Don't wanna blow my shit up. Also, it's getting cold out and I have a newborn, I don't wanna be left without heat for a week while I figure out how to do everything myself. Also, I already have two other big DIY projects started and don't have time/energy for a third
So I am building a battery pack for an electric scooter using a bunch of rectangle lithium batteries, and I'm to the stage I need to sort out the cell separators.I planned to use g10 fr4 epoxy board but I designed one of the larger separators and the single piece would cost 38usd to have cut out and sent. I intended on having it all cut out and designed so that it slides all together but nope lol, it would cost like 300usd++ for that.So now I must use smaller pieces and somehow cut them myself and figure out how to join them together.Has anyone here done something like this? What's the least painful way to cut g10 with some level of accuracy?
>>2873797It's fiberglass. You can cut it with damn near anything. Carbon steel/HSS blades will dull fast, but they work. I've used a coping saw to cut out PCBs before, even.

>>2870557>I have a decent DMM but the probes are too chunky and for whatever reason, it cannot reliably test stuff that's in circuit.you can always make your own with some wire. Keep in mind that when components are in circuit, there's not just the path between both leads of the component going through it, but also through any common (ex ground) paths on either end of the component. This WILL fugg up your measurements regardless of what tool you use to measure.Also, if you're looking at an op-amps output you'll want some impedance on the probe or else you'll fuck with the output. Solder a 1k resistor on the output in parallel and clamp your probe on to that (or just have a probe with a 1k in series)
>>2870557>I don't know how these SMD component testers work but they do have a mode to test stuff in circuit.ok tbf it might be doing something fancy but I wouldn't know what
>>2872384power and signal are sperate - AA's keep the controller on, button pushes send a signal yeah? NOT sends the opposite signal of what it gets - "no signal" is code word for the signal is 0, "there is signal" means the signal is 1. If the NOT gate gets a 0, it sends a 1. If it gets a 1, it sends a 0

>>2873789
>>2873790Can I offer you a relatable image in these trying times?
>>2873751>>2873767this guy is trying to help you.the principle is it's plugged in without the plug. the same way you'd plug a plug in and have the 3 or 2 prongs. (hot, neutral, ground), it's the same thing but without the plug.make sure power is off and you are wearing shoes. watch a few YouTube videos on how to wire a light or something.it's pretty simple.black to black, white to white, green to green.when disconnecting.disconnect black, white, then green or bare copper when connecting, reverse it. connect the green first, then neutral then hot.Comment too long.

>>2873639If the MCU has an internal analog comparator, it might be usable in a sleep mode and able to output an interrupt. Otherwise, use a low-power external comparator and voltage reference.Anything else like MOSFET gate thresholds are probably not reliable enough.
>>2873710what kind of battery? some of the low power modes draw less than the cell self-discharge rates.you could wake it up with a low-power timer every hour and check things, then go back to sleep if nothing’s going on.
>>2873713They are going to be on LiFePO4, so self discharge (winter) is very little, 1-2% a month. But I intend to allow them to fully discharge because of the nature of their purpose, so it could get in a situation where if the solar panel is damaged, it will run down to 2v before shutting down since that is the maximum discharge voltage per the datasheet. Due to redundancy, it might get ignored for quite a while before it's fixed, so I don't really want to have any load past 2v cutoff.Now that I think about it, I suppose the mcu could do the low voltage cutoff at 2v and just remain active for 48 hours, if the voltage does not go back up in 48 hours, it cuts it's own power and the cell is fully disconnected requiring a human to go reconnect it.
>>2862495Can anyone tell me how do I figure out pinout for a given board?I have ESP32-S3 with SIM7670G module from waveshare. There's a verbose wiki page with handful of links:https://www.waveshare.com/wiki/ESP32-S3-SIM7670G-4Gbut I'm struggling to find out what are modem rt/tx pins on this module

Badass anon. Jealous. Do you get to live there for free?>>2873629This guy's talkin sense. Commercial real estate just has a spooky vibe these days. I've lived in a couple big buildings that had supers or handymen, all nice people. But jesus, I would hate having to deal with the scummy, shady ass management at those places on a regular basis. I never had any serious disputes with them, but every interaction was loaded with negative presumptions and just gave me the creeps. Like talking to a disingenuous car salesman, or a righteous cop, but even worse
>>2873396are you allowed to do repairs on the elevator? it's not allowed here
>>2873723The old super got to live there but they phased that perk out, I assume to make more money.I think the management issue is a bit of a two way street. Lots of scummy tenants that are always trying to dodge paying their bills, wrecking the place, or complaining. To your point though a lot of these bigger companies price gouge, cut corners and just see their tenants as numbers on a spreadsheet. >>2873738Nah, we have a contract with an elevator company. They do monthly preventative maintenance and have their own room in the building that's kinda off limits. The tech is super nice though, showed me the pit, let me ride on top of the car, and showed me how some of it works.
>>2873706Where are you located (generally)? I'm curious to about your COL.
>>2873396youre a house nurse for boomers lol.the fact none of the older ladies tried to hook you up with their grandkids or daughters means your a piece of shit too. they are pretending to be nice and probably hate you.
will house 4 full-grown rabbits in 4 seperate enclosures. each unit is 70cm×96cmTotal project cost: 0Auall materials were repurposed, reclaimed, rejects or scrap. this includes all fasteners, mesh & hinges. total time invested: 6 hours.
>>2873538They seem like a better animal to introduce and let run wild and then just go hunt one when you want.Maybe give them some nice houses and scatter some food but it's such a fucking pain to keep rabbits.Like monitor the population and health and food supply and give them some bonus food but keeping them in a cage is a pain. Handle it more like bee keeping then intensive farming.
>>2873665If your gonna do that just do pigs. That's how they're traditionally raised. At least European style. The Chinese did all kinds of weird stuff with pigs
>>2873669Someone already did it for me. I can just go out and get one.
>>2872541not gonna lie. I hope op experiences prison and understands from the experience, the condition he keeps his animals in.they sent a commodity unless you are friend.

>>2873638ATF is going to shoot your dick off
>>2873625>like $200 for a grain mill.I use a corona hand mill, they're pretty cheap even though they aren't idealAll sorts of DIY mills too
>>2873625The point of full grain isn’t primarily for the savings. It’s because it gives you more control over the beer (mixture of malts) and it tastes better (inb4 extractfags try to act like their beers don’t have the unmistakeable extract twang in them)If your primary concern is cost over flavor/time enjoying the hobby why don’t you just go buy a 24 pack of natty and call it a night?
>>2868574The meads been going for a month and has seemed to pause. Doesn't smell rotten but doesn't smell great. I don't think I want to try wild yeast again I think controlled fermentation is better. I'm cheap so I'll just harvest yeast
>me: capable american, living in America>wife and her parents: SlavsOur electric kettle gets used every day for coffee, tea, and occasionally preheating water for a pot on the stove. Figured one of these under sink water boilers would be worth the cost and effort for always ready near boiling water and it would be one of those perfect Christmas presents to that family that no one knew they needed. Seems gimmicky but I'd rather see these in more kitchens rather than garbage disposals.Any idea why the faucets are so expensive while the boilers themselves seem reasonably priced? Sure it's the brands treating it as an artisanal appliance and not that you need special materials to stand the 200F-ish water.Energy costs shouldn't be too bad and it will be justified the more use use it gets. I might share the extra in-line water filter used for the refrigerator icemaker because why not. Any opinions why these aren't more common in America before I spend the money and drill a hole in my countertop?

What stones do you use?Back when I lived in the city i could take my knives for a quick sharpening, $2.50 a blade. Now its like $6 each and im not were near the shop.I'm looking to buy a nice set of diamond stones.How many do I need, and what grit?I have Zwilling knives, and a bunch of other blades that need to be sharpened.
>>2871749I use a 1000/400 diamond stone. They're pretty affordable now and cut fast and never need to be flattened. If it's just for pocket knives and kitchen knives, you'll probably never sharpen enough to wear it out. 99% of the time you'd just use the 1000 side. I also have a leather strop that I use buffing compound on. The compound is optional though. Any strop is 100% worth it. I do woodworking so I sharpen a lot and want it to be relatively fast and easy. I don't even use the honing fluid on the diamonds anymore since I'd rather just buy a new stone at a slightly accelerated pace than use it.
