I'm repacing a leaking high pressure hose and need to refill the a/c. This might upset the purist shop workers but I don't want to buy a vacuum pump for a one off repair so do you think using the engine's vacuum will work as seen here anons? https://www.youtube.com/watch?v=w9UKHfQFwM8I also have spare vacuum hoses and adapters on hand.
>>2991744That's butane bud.
>>2991818
Would intermittent hot and cold another car is having likely be the expansion valve? Also I know pic related is far from professional grade but will it get the job done?
>>2991878I got the vacuum pump and the manifold gage for $66 on Alibaba. I'm not sure if those cheap leak detectors are worth it.
>>2991878>>2991900Also is you are on the US those can valves don't work great on the self sealing R134a cans. They work but not great and are only $3 on sale on Aliexpress.
I know prepping is a bit of a meme, but what are some of the best food items to store long term? Is rice one of the best emergency foods? It’s cheap, it lasts for a very long time if kept somewhere dry (relatively easy to store), and a person can survive off of it in dire situations.What does /diy/ think?
>>2991489>back to basicsAh a fellow man of taste.
the real prepping is to insulate your house until its a passive house, have a vehicle that uses less fuel, like a moped or even better an electric one and having some solar panels.to lower your needs is the best way to prepper. its also actually useful before shit hits the fanmost prepper shit is hoarding or larping as traditional farmer and shit which is absurdly inefficient energy wise. copy modern industrial agriculture and farming, not traditional, as they use less resources per kg of output. a greenhouse will be easier to tend, produce in winter, have less problems (plague control is way easier there, its an enclosed space)other than this is sane >>2982822 maybe make it 3x
>>2991682it may depend on climate but I don't think you can create a passively heated and cooled space through insulationa heavily insulated home has no drafts and needs active heating and cooling to maintain the right temp, provide airflow and reduce moisturethe high insulation value means the energy required to maintain it is low, but once you stop conditioning the house, from a prolonged power outage, it's going to mold up and heat up from body temppassive homes need to be designed to be passively heated and cooled from the start with strategic insulation and ventilation
>>2991790passive houses normally uses mechanical ventilation to get fresh air with an energy recovery system. which sound complex but in the end its just two fans and some fancy duckwork and filtersthe idea is that you get bellow 10w/m2 of maximum usage, and this is perfectly reasonable, i know an actual example in an area with pretty harsh winters, i think all it had was two 500w heaters in a 120ish m2 detached housecooling is again not that much harder, bc you are lowering a ton the needs.just get a small non grid tied inverter. hell you could use a dc heater. and even a balcony solar system would work for a passive house.and you can use still use any fuel stove in a passive house, you are not limited to electricity, a hobbo alcohol stove will be enough to heat it
I'm grateful for preppers because they'll leave behind a bunch of near-full food caches for me to find as I roam around the country
Yesterday I was at a yard sale and found this. It's pretty sturdy and also a lazy susan. Should I sand and paint it or sand and re-stain it? I was also thinking maybe doing a polyurethane finish?
I think thats a CD case holder

People in all sorts of climates live in these kinds of buildings. Typically, in the Southwest, appropriate local soil and water are all that are used. The soil just needs to be the right mix of loam, sand and clay types.For anyone interested, history and how-to:https://pubs.nmsu.edu/_g/G521/index.html
How about ferrocement? Based on the token predictor, it should be possible to create a waterproof and still reasonably vapor open outer shell. Meaning you could construct both the roof and walls out of the same material. Not as cheap as dirt, but very low tech and a bit more solid. >>2986720very cool. I remember reading they had 95% private home ownership at some point.

>>2986530picrel is the DIY solution

Do shills disguised as posters exist on hobby machinist forums? Wanted to find a review on the little machine shop's products and I got overwhelmingly positive opinions on them. When it comes to practical machinist they stone you for mentioning them.
>>2991739geezers are a peculiar lotthey love to brag to each other when something goes smooth despite how little effort was often involved on their part and its a flex how they could just throw their card down and make it happen they hate showing the weaknesses of being taken a fool so the ones that got a short stick on junk often stay silent to avoid being torn to shreds by the rabid jackals that are forum regulars now consider the average oldfuck that has time to type out tool reviews is usually long retired and relegated to subdivision life where his shop is 18 sqft of the garage and the most involved machine work hes done in the past 5 years is drilling out scamazon chinkshit plastic lawnmower wheels for his wifes rolling garden stool because they were 12mm and the bolt was 1/2"
I started using a Hardinge HLV-H at work and now I hate my shitty chinesium 8x12. I don't think I'd even be happy with the largest lathe I have room for, which would be something like a 9x19 Grizzly G4000. How do you stop exposure to professional tools from ruining your hobbies?
>>2991409>How do you stop exposure to professional tools from ruining your hobbies?you dontsoon youll fully realize the cake is a lie and things in fact do not get better as you get older after a certain point of no returnt. loved building shit in my youth with a hammer and a hacksaw then spent a decade in fully tooled r&d
>>2991416Well that got dark fast.
>>2991409I have a clone of that 9x19. Skip it. I feel like you are like my twin. My solution is to just sneak in my personal projects at work. The Hardinge is my favorite lathe to run. It is just sweet. We have a Hardinge and a clone, and they're both awesome.
>>2991409You adjust or keep them separated. Me for example, used to be big into 3d printing. Then i realised the whole better materials meme is an endless rabbit hole, while you can order a fused nylon part for a few bucks online and it will crush your home printed stuff in every metric. Eventually 3d printing makes only sense in the low or very high end.I now use that knowledge for other stuff. Currently automating my shroom farm. Still lots of tinkering and wife appreciates the results.>>2991416Haven't seen that image in ages. Thankfully i took a turn to the right since then.
soil nailing. my wall footer is exposed, i tried reversing the grade, but damage is done. plan is to dig about 2m instead of 4m and then repoint the wall. im struggling to dig a diagonal bore so i plan to extend my drill with some pvc. have you tried boring a few meters, how did you do it?
>>2991554>boring a few metersif you don't have pic related, you are not going to achieve much - hand auger don't really go bellow 35-50cm. Your option is to hire a mini excavator and dig a trench around the perimeter, and lay a retention wall from bricks.
>>2991554>pvcYou'll learn the hard way why >>2991639 existEven hand turned soil augers only go 85-100cm deep, the further down you go the harder and more compact the soil isIt will fuck up a hardened steel hand tool, I'm pretty sure PVC will rip itself apart when you go deep enough
>>2991651one lift would be enough.>>2991639i like the idea of putting in a retaining wall probs a MSE, geogrid alternatives are cheaper than rebar.i discussed it with my better half and she reckons that a dry soil nail reduces risk, i can rent a rotary hammer and put something in without digging, shear strength of the rebar is the only and square cube law screws my friction/penetration depth. concern is the bore hole equivalent of a gopher hole will collapse the hill, i might have exaggerated the risk to loosen the purse strings whoops. i have been watching pvc well digging is it that easy?
I'm planning on totally redoing my lawn by rolling out cardboard and putting new soil on top of it. Would doing so kill whatever lives in these holes across my yard or can they dig out?
>>2991664You're essentially asking whether a rodent can chew through cardboard or not... The answer is yes they will chew and dig their way out easily.
>>2991678basedSorry I'm new to the planet
>>2991679Don't worry about it, just get some poison and pour it in their holes. Or get some cats (easy) and don't overfeed them (hard).
i love having a shed, i can just go out and paint things at 9:45 pm. all my wood is dry. and i built its all myself.

>breaking stuff even worse than when it started because you're still trying to grasp the processI hate this feeling.
>>2988498I bricked one of my security cameras and my car stereo trying to modify firmware in the last week lol. Going to fix both for sure, but it still sucks. If you want to learn, breaking shit and then figuring out how to fix it is one of the best ways to do it because the fixing part generally means understanding how it works on a fundamental level.
>>2989018make it your dayjob
>>2988498This is why you should practice on devices that were going to be e-waste anyway had you not intervened.
>>2988872Same. I have a wife and young kids now and almost zero time to myself during the day for hobbies. It'll probably be a few years before they're old enough to not need constant attention.I installed a water heater yesterday and I don't really feel any satisfaction, just irritated that my long weekend was wasted dealing with a DIY project I didn't want to do.
i tried to repair a shitty amazon 3.5mm aux that had a failed solder joint but i didnt know whatever this shits made of is butter so i destroyed it on accident.
Frens,How do I kill a tree without using girdling or glyphosate?I also have some type of Jumanji-like vine that won't stop growing on my fence and I've tried killing it for years. Can I drill a hole in the tree and put some kind of chemical in it? The roots of the vines too?

>>2989982>>2989996The voltage dividers (relative to ground) can't work since the solar controller operate via switching the negative side of each load/source. I tried it: gives something like 13V with sun on the panel. Panel disconnected from controller gives 18V.There's a similar topic on arduino forum, this guy say something about 5 resistor but is dumb enough to not post any schematic. Do you guys could provide one?https://forum.arduino.cc/t/measuring-voltage-and-current-of-solar-panel/971316/9

>>2982331I think frigate might have features for recognizing faces. It can be set up to detect humans and has some advanced features I haven't played around with yet. I'm using 3 Rasp Pi Zero 2 W's connected to and old laptop running Devuan Linux (anti-systemd /g/ hipster) + Frigate via Docker. Works pretty good as a static camera. Annoying to get placed anywhere. Also it was a bit fiddly to get the streaming working right. The camera quality isn't amazing either though could be user error. I heard someone else uses a wyze cam v3 with thingino firmware installed through a sd card, but I haven't tried those out myself.
>>2989878I'd be worried about short circuits.
>>2973556Old 8-bits were made of embedded components and spiritually Pi-like in a way but they still weren't really designed or intended to be hidden in larger assemblies as fixed controllers in the way you'd use an SBC with the same hardware even if they were still good at it
