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.

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!

What's the most cost effective way to convert 24vdc to 120vdc for a purely resistive load of like 2kw?

can I just make an iron core transformer myself? or use something something microwave oven transformer?

>>1703865
You can't use a transformer on DC, doesn't work like that buddy.
Transformers and coils generate and collapse magnetic fields due to CHANGES in current, not just presence.
A boost smps switches the only on and off very quickly and changes timing based on the output to try and hit a target output voltage.
Dumbest way you could do it is get a motor to drive a generator, you could wind them yourself if you like

Why the fuck would you ever leave MA if you want to be in the trades? If you aren’t retarded (granted I don’t know since you want to work for fucking roto rooter) you should get an apprenticeship with 537, 550, or 12. I know for a fact that Boston is one of the most lucrative places in the country to be a tradesman.

Thats how franchises work. Look at Geek Squad at Best Buy. Over charge and under pay. Companies like this don't want people that know the job area or have experience.
>>
>>1703819
I'm going to disagree a little, Anon. Franchises usually take serious steps to make sure you're competent, because if you fuck up it's not Anon Smith's Jackoff Service that customers bitch about, it's Roto Rooter, or whoever you're franchised with. They also handle a lot of things that get glossed over when it gets simplified, too. Advertising, scheduling, accounting: that all costs money, and most people don't even think about it. I'm sure the company overvalues itself and could pay the workers better, but it's a free country, and if you want to hang your shingle out there and start your own business, there's nothing to stop you. I'm saying that for real too, not trying to be a dick.

Is there anything cool and interesting when it comes to offroad bikes you can make on a benchtop sized lathe and mill?

what printer do you have? i suffer from the same thing but i hear a lot of printers you can hear across a house which is excessive.
>>
>>1703810
Thats ridiculous. I have an ender 3 and you can barely hear it outside if a room when stock, and it's not that hard to quiet it down. Stepper dampers or a quieter board will eliminated the motor noises, and you can replace the fans if you really want it silent. I can't think of any reason why tiny steppers and fans would make enough noise to be heard across a house, but I suppose I don't own every printer.

I have a CR-10 and Ender 3. I have the squash ball feet on the CR-10 which dampens the noise a bit too. So perfect for my tinnitus.

The hot end is just a basic cheap Bowden tube heatsink with a bronze heating block i got off of alibaba for a dollar each. It maintains the heat better and because both sides have no screw-ins I can change my nozzles much easier by holding them in place with a adjustable wrench and using a ratchet for the nozzle.

The bronze also is a bit tougher than the aluminum so you won't strip it as often by changing your nozzles or over tightening by accident

>American wire gauge (AWG), also known as the Brown & Sharpe wire gauge, is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258.[1] The cross-sectional area of each gauge is an important factor for determining its current-carrying ampacity.

Do you really care this much about a place you don't live using a system that doesn't affect you? If it eases your mind (because I'm sure this hits home for you) we produce and dose our blood pressure meds in metric, just like they do for you wherever you are.

I saw some pleb on here recommend the xiamoi air filter as a sort of diy solution, since you can just use the filter cartridge with some sort of fan and not pay for the housing, or something like that. I googled around and found reviews showing the Xiamoi did a terrible job cleaning the air.
The people at Smart-Air seem to have shown that a hepa filter strapped to a fan can perform massively better. If you believe their data, yada yada. Anyway I took some cues from their design and made this monstrosity. Not a real HEPA but it was cheap and was the highest filtration level in the store. Seems to be helping a lot with air quality. Ever since I got a cat my asthma has been fucked. This helped.

Post diy air cleaners and related stuff pls

Must be a weird vortex action or something because it almost seems like the flame gets more deflected farther away, at least in the center. There is a dead zone right in the center in front of the "hub" of the fan blade, but there is no noticeable difference in flame deflection when I move side to side or up and down... anyway thanks for reading my blog

New design doesn't let air pressure escape in front of the filter where the ducting touches it. Sealed up the corners. Also offset the filter an inch so the entire filter can be used instead of the center only. Should give a little less resistance that way. Which is good since I added a pre-filter.

Maybe. Or it’s one of those things that gets a little bit tighter every time you use it so it’s impossibly torqued now.

I’m a dumbass for using the socket, my autism is off the spectrum having a broken socket in my set. Ordered a new one for $4.50 off Amazon, not even worth trying to warranty it for that price. Shoulda spent $20 on the SK just to see if that is significantly better, but I’m sure that would break too.

when reading about heavy machine tools, everyone will always say that aluminum extrusions, steel plate, etc shouldn't be used to frame things like lathes or mills because they don't have enough damping to negate the vibrations of using the tool, which will give you bad tolerances and surface finish. yet people like https://www.youtube.com/watch?v=Lzytexbrdlg are able to achieve good quality parts and high precision using scrap. how is this possible? I thought machine tool frames needed to be heavy for parts to be reasonably accurate.

I want to buy a miter saw for cutting steel pipe. With most videos I've watched of people doing this, there's a decent amount of sparks flying away from the tool, but they're always inside. Do I have to worry about this causing a fire? I have no garage or way to use this tool outside. I guess I could use a hacksaw or something but a miter is just useful to have anyway.
>>
>>1703852
Get a cold cutting saw, and get an acutal metal cutting saw not a wood saw.

As for fire, yes, if its spitting sparks you got to worry about fire. Just shove a board behind the saw.

Not my personal one, but my tool box at work is all setup,5s, and what not and people just take shit and toss it back in random ass places. 1st shift bitched that I 5s the tool box saying its stupid and told me to stop moving stuff around (been there longer then her, she has been there for a little over 3 months now), which I find funny because she will move shit around and hardly cleans up after herself. Worst enough when she doesn't replace stuff that she broke or lost and throws stripped or broke screws in a random spot in a drawer.

I was just pissed because I wanted to get rid of the thing at a certain point and a couple of friends were interested in it, but they didn’t even know what to do with the thing since I couldn’t get a title. Hell, I may have gotten the thing running if I knew what the hell he die with a couple of the fairings and title.

We just mostly ignore each other these days

Like when I visit, my dad usually just fucks off to another room leaving me talking with my step-mom (which I don't mind, I love her like a close aunt).

Only thing we can talk about is when to change on studded tires and other car maintenance-y things. And the dog.

I'm a failure to him, and we both know it.
