When did you realize you had the DIY/engineer autism? Are some just born with a mind for understanding mechanical tasks?Sometimes I feel like it's a curse but I can live so cheaply doing things myself and I prefer it vs paying some jewish retard who probably isn't near as detail oriented.

>>2993159>ai sloppac'mon man
>>2994777maybe AI slop but what it says is spot on.
>>2992704This. I did this a lot plus fucked with electricity a lot. Never did anything with it. Got into computers at a young age and learned as much as I can. Got a degree in IT. Could never get a job. Wish I went in for Engineering instead. Wasted years working dead end factory floor jobs getting treated like trash. Started a new job after getting let go in December from a different factory. 38 now. Doing the same old crap. They had a position open that they had a hard time filling mostly because pay was not that great. Applied and got the job. Now I work in an engineering department being an engineering assistant and doing some IT work (do it because no one does it and the 3rd party guy we pay takes a week just to do simple shit).As >>2992703 said, being able to live cheaply.This is because I can fix most of my own stuff and make it last longer. Plus stuff I can pick up for cheap or free that needs fixing or something basic done to it. My home lab is built up mostly of computers that I got for free mostly because they cant "run Windows 11" or people think something major is wrong with it but its a simple fix.
Anyone know what to do to make a cyber deck? Do I need a raspberry pi because it would be hard for me to buy one online. Any alternatives?
These look cool, I could use something like this.Ill try making one with an orange pi, wifi would be handy, but no need for speakers, mechanical keyboard or much graphical processing power. I Should be able to make it fairly small with one of those keyboards meant for smart TVs and a few 18650s.
quiero hacer mi cyberdeck con un celular Samsung j2, mi pensado es rutiarlo y instalarle una distribución de linux que no consuma mas de 200 mb de ram ya que solo cuento con 2 gb de ram, soldarle barias baterías para extender su capacidad, agregarle un ventilador para refrigeración y por ultimo un multipuertos para el teclado, mouse y memorias. solo lo utilizare para escribir libros ver pinteres y redes sociales como 4chan, ¡hay algo que halla paso por alto?

I am a very capable bladesmith and metalworker and I absolutely adore the appearance of mercury gilt objects. The only issue is that this process is incredibly toxic - does anyone here have experience handling mercury vapor? Apparently you can buy mercury vapor masks. I don't have a fume hood but could use my enameling kiln to burn off most of the mercury while I am very far away from it and then go over it with a butane torch while wearing a mask. How horrifically stupid is this idea?
Can you direct the fumes to a drying tower with elemental sulfur flakes or some shit?
>>2994214Looks like brass. I don’t know what the big deal is.Everybody’s going to think it’s brass.You’re going to bring chicks up to see your “mercury gildings” and they’ll see it’s just brass and jettison.
>>2994214Try damascening. Is much better than gilding and not toxic at all.

I'm working on klipperizing a makerbot z18 with an octopus pro mainboard.How do I connect my regular computer to the octopus board? I have it plugged into usb, the board is lit up, and windows is recognizing it as a USB COM device, but how do I actually communicate with it? Ie do I use a terminal, or is there something like putty with ssh but for com ports? Or do I not "talk" to it at all in that way? What else do I need to know here that I am probably not getting right now?
Every day carry? How about home carry? I live in a 4500 sqft hundred year old house. All my tools are in the basement, but I have to work on shit on the other three floors, in the detached garage, and outside. I don't need a grab and go bag; I don't work on anything at my job, and no one is calling me to come over help them fix anything. As much as I try to plan ahead I am always running back to the basement. Of course I am trying to put together a tool box or kit, so I'm here seeing if any anons in similar situations have any suggestions or advice. Get good? Suck it up?

>>2994580i live in just a shitty apartment but unironically keep an old camera bag as a bike tool repair kit. a shitty t-handle driver holder, a 1/4" ratchet, the usual bits (three sizes of philips, two flats, the four most common hex, and a 6mm hex to 1/4" socket holder thingy), a small adjustible wrench, and some other bits and bobs like a roll of tape and random stout pieces of metal to use as shims/wedges/prybars. it does 99% of jobs around the house so instead of pawing through my mounds of real tools I just reach for that first. >>2994591this unironically works. a few times when i've started to lose individual driver bits or got annoyed at having only one of something, I just got another from the dollar store just so i dont have to break apart a kit i've made up so often. just dont do this with allen keys/hex drivers. those things accumulate so fast. and then one day in a pinch i bought a big bag of random ones at a thrift shop and now they just litter my apartment and somehow the one i find is always useless for whatever i wanted to fuck in half
>>2994757also this, i had a cordless drill but found it both a little weak and always annoying that it was running out of charge in the middle of whatever I was doing just as i hit Fey Mood levels of flow and now have to go insane waiting for it to recharge. got a cheap corded one i use with a shitty Princess Auto press to do serious drilling and have the cordless as just an electric screwdriver or for reamingalso dont sleep on actual cargo pants. nerds wear them because they're stupid military larpers but i have had times at work where i regret not wearing a belt because I'm carrying like nine wrenches and a pile of pseudorandom hardware in my pockets5.11 is a meme but i have excactly one(1) pair of 5.11 pants and only because i found them at a thrift shop. i'd never pay MSRP for them but they're easily the best work pants i own and every pocket is expertly intuited by a retard to enable this particular retard
Last Threads: https://warosu.org/diy/?task=search2&search_username=artbyrobotTo begin: the project goal: I am working to make a series of humanoid robots. I am using a Biblical theme of naming the first 3 robots I make Adam, Eve, and Abel. The goal is for these robots to have human body inspired musculoskeletal systems, advanced AI, and that they look human and pass for human to a casual observer at least at a distance. They must be able to walk, talk, run, dance, do sports, do chores, manufacture products, and make more robots just like themselves if not even better. My aim is to build a single robot arm and head and then add sufficiently advanced AI to that arm and head to enable it to build the rest of its own body for me. This way I am delegating the work of building the majority of my first humanoid robot to that robot rather than doing that work myself - and this is to save me time.In a like manner, my goal with the AI is to code just enough AI that the AI can begin coding itself and this way I don't have to code most of the AI myself because it will self create itself. I liken this to building a seed and that seed growing into a tree because for me to code that tree would take too long for me and just creating the seed would then save me time.
>>2994245There was this one guy in that thread who seemingly never even seen a model kit before, it was bizarre. Also him (or a guy that talks like him) admitted it wasn't criticism, they just don't like me

Ok I managed to apply the UV solder mask today and it seems like it worked quite smoothly. I used the tip of a small sewing needle to spread it over the trace and then held the UV light on it for 10 seconds to play it safe. I used transparent UV solder mask so you can still see the trace but its a bit more murky/cloudy when you see it. I used the tip of an exacto knife to put little scratches on the UV solder mask to test its thickness by feel and test its durability a bit to scratching. And ensure it was fully cured. It was very hard and durable and seems to have gone on fairly thin. The question is, is it too thick/proud of the surface for the soldering on of the chip over it? This is the million dollar question. Because if the mask lifts the chip up off the PCB even a tiny bit then the soldering may not reach between pads on the IC and pads on the PCB, failing to bridge the distance. That is my main concern. If I have any issues with that, I will have to reroute this trace to go around everything rather than on the shortest path like it is now. The shortest path leads it under the IC and led me to have to mask it. Extra steps like this are a bit annoying. I kind of wish I just routed it around everything out of the way more. Then I would not need to UV solder mask at all. Perhaps in a future board iteration I will do this improvement but we'll see. For now I made several boards and want to stick to them since it would be more work to remake them all.

When I was 16 I tried to shell swap a New 3DS XL with no prior experience tinkering with consoles, and fucked it up really bad. So for the past 2 years it’s been sitting in a plastic box while I wait to find somebody competent who can fix it, anyways I’ve been using another one since then and was wondering if there are any strange projects that could be done with the old one (besides growing a pair and fixing it myself). Any suggestions?

Help. I lost the eye nut to this bird feeder and Home Depot no longer sells this item. How would you fashion a hanging feature to this? I have a Dremel and common tools
Loosen that flanged nut and put your wire under it

>>2994522I switched from that mix with the little white shit the sparrows toss out constantly for black oil sunflower and I have to refill it less often and now get better birds. FYI.

I live in a trailer off grid. I have propane tanks (the standard kind you see at a gas station) and gasoline jerrycans like OP pic.I’m wondering if they are safe from lightning and if not if there are any projects I can do to make them so.
Yes
Try not to store them in or around trees or tall structures, otherwise you should be OK.In the future get some real metal jerrycans instead of those barf-o-matic plastic pressure bottles, and search for the SQTDDTOT thread before posting.

I have a polycarbonate greenhouse like this .The door is very light and it's on hinges and swings open outside like a normal door.I want to design some sort of doohickey to automatically open the door in the morning and close it at night.I am experienced in electronics so making the timer which controls a motor is not an issue , but am unable to think of some simple mechanical solution i can easily diy, that will actually utilize the motor spin to open the door itself.It also has to be possible to open the door manually if it's closed.Any ideas fellow anon frens?
>>2992941just use meshes in the openings
>>2992936the main problem of motor on the door is still being able to open it by hand.presuming that the door is on a slide like a normal greenhouse i would say some kind of motor and some kind of timing chain (plastic) at the top and put a bolt through it into the door. a microswitch at each limit, some kind of 8 bit mcu (as much as i hate them arduino would suit someting like this but an esp whatever means you could control it wirelessly ) a little motor driver and you are good to go. stepper motor and brushless driver module is the easiest way to have any kind of control over speed, you could even ramp it up i suppose. and then as long as you arent supplying hold current to the motor you can just push the door by hand anyway. then if you want to go crazy maybe an ir distance sensor and you can set the actual position you want the door to be.i do hate those window temperature openers i never could get one to work properly, so as much as i want to tell you to replace a second window with an opening one, i will support your retarded quest. good luck and god speed.
Make some ghetto fab setup with a servo motor and a quick release rocker arm attached to the handle for when you need to manually do stuff
>>2992958do you really need a greenhouse if it gets that hot?
>>2992936You could do a solar powered fan. When the sun is out it will blow.
My dad was really smart so he would fix anything that broke, dishwashers, driers, tables, lawnmowers, leaf blowers. Every time he made a mistake or dropped a screw he would say, "God damn it! Damn Chinese bastards! God damn retarded chinese cocksuckers. Stupid cheap chinese engineering!"Lol.

hello. how can I improve this current limiting circuit?the comparator always swings around when limiting the current. there must be a cleaner way to implement this.https://filebin.net/n2r04yvmld1c1vvv/voltage-adjustable-boost-converter.aschttps://www.instructables.com/Adding-a-Current-Limit-Feature-to-a-BuckBoost-Conv/
>>2994722It’s supposed to “swing around” when limiting the current on a varying load.If you want to “dampen” the rate of change, you could probably add a cap across the inputs of U8 or something.
>>2994722If you want smooth transition from CV to and from CC, you’ll want U4 to have finite gain. U1 already has an error amplifier on its FB input, adding too much extra gain inline with this will make it unstable. Try a gain of 100 first. You may find that there’s no gain that results in good stability while regulating the current precisely enough, in which case you could add some integral gain to U4. Differential gain could help too. Pic related is an op-amp with both differential and integral gain. Though maybe there could be a cap or resistor across C1R1.Not sure what R4 is doing.Also unless U8 is a dedicated high-side capable current sense amplifier, it’s probably better to do low-side current sensing. Common LM334/358 op-amps can sense down to their ground rail.
