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!

I saw some extensions for sale in a shop near me, gas lens, do they make a difference or save gas? Are they worth buying? Because they're bigger than normal cups and cost more
>>
>>2774132
>gas lens, do they make a difference or save gas?
They give better gas coverage. You can turn the gas flow down for similar coverage, or use a higher flow to do things you can't with a normal cup, like using an extremely long electrode stickout to get into an awkward place.

>Are they worth buying?
Yes, if you regularly weld and/or have situations that need improved gas coverage. They are also more prone to damage (they do last a while, but it does happen), so you should keep a spare handy.

>>2774153
Thanks, I saw welders on yt shilling them for stainless but I didn't see the point since you can wire brush and grind oxidation after you're done
>>
>>2774132
you can reduce the flow a bit on bigger cups and still get coverage. i don't think a #12 cup could even work without a gas lens.
most of the time you're gonna be using more like a #6 which isn't really flowing much, so you only get the side benefits.
the normal gas lens #6 lets you stick the tungsten out a bit more.
the "stubby" gas lens #6 is a very short cup that still gives ok gas coverage.

i get daily power outages which will last 1-2.5 hours. to add insult to injury, my IP address changes when i lose power, forcing me to reconfirm my email on discord .. etc.

the obvious solution is UPS, i looked up some models online. the ones available will either work for 15 minutes only, or go multiple hours but cost a kidney.

i thought maybe a 20,000mah power bank with 5v-12v adapter. this will solve the internet connection issue, but won't solve the IP address situation. since i'll have to switch the power plug from AC to power bank each time i lose power (1st power cut), and switch back to AC when power is restored (2nd power cut), then recharge the power bank.

alternatively, i could just leave the power bank connected to the wall, and the router connected to the power bank. but that way the batteries will die in few months, not to mention the possibility of causing a fire.

i need uninterruptible power to the router, that only needs to be set up ONCE, with no manual effort on my behalf. surely diy can help?

If you have guaranteed power for one or two hours a day just get a big 12V battery , run off that, and manually switch to line power+charging when you have power and the battery is empty. You’d only need to charge weekly with a big enough battery

I have a set of stanley brand batteries a charger and a drill and now I'm looking into getting a few more tools for my home. Problem is stanley is a dead brand, at least here where I'm at.
There's nothing in stores, there's almost nothing online and even if I managed to find something I don't think the dewalt dealers here will work with a stanley warranty.
Do I just sell my drill and batteries and start over? Or use adapters and buy dewalt or something?
What would you gents recommend?

These threads are not useless, battery deprecation, incompatibility, and switcharoos with cheap chinese cells after the initial reviews are in are very common problems, you’ll face them every fucking year now if you’re a heavy power tool user.
>>
>>2773873
Regardless of what tool brand you buy into you should learn to rebuild packs. A $40 spot welder on ali express and learning how to identify what cells make up the pack will basically keep the tools running indefinitely. Or save the $40 and buy cells with tabs installed for a few dollars more. Or solder directly to the cells but be warned that if you don’t work extremely quickly the cells will explode and even if you do work quickly the heat transfer will degrade the cell and make it perform worse.
At least until manufacturers pull apple bullshit and start including ICs that communicate with other ICs on the tool to indicate how many cycles a pack has gone through and to permanently disable a pack once it hits a “dangerous” amount but afaik no one does this (yet)
>>

Fwiw, the PC batteries could possibly fit. Stanley Black & Decker has compatibility between some other brands. Like IIRC, the Mac cordless tools and this industrial grease gun (Lincoln?) and possibly some other 20V tools from across the company’s portfolio actually fit DeWalt 20V packs.
>>
>>2774057
>>2774059
Yeah my quick research showed that there might be some compatible brands to the batteries I have, but the problem is basically the same. I can't get those tools here.
Basically I have to choose between makita dewalt or milwaukee.

Perhaps you're personally familiar with this building technique, so you can recognize that for what it is.
But it's not clear based on the photo without that additional personal context that you possess.

How dangerous is it to remove asbestos popcorn ceiling yourself versus hiring someone? Like am I gonna get cancer or some shit even if I wear a mask or do I need more than that?

The thing about hiring someone is they put up barriers and filter the air.

See, once you scrape that shit off the ceiling, the dust is going everywhere. If your only exposure was when you're scraping, the mask would be fine. But that shit is going to go through your house, into vents, etc.

Short-term exposure may not be that big a deal, but you're going to be living with it for a while.
I'd hire someone who can put up plastic and filter the air, etc., so I don't have to wonder if I contained it well enough.

>Graphite is conductive
Less so than the copper strands in conventional and expensive desoldering wick. I'll just cut or pull a tiny pinch from the carbon welding mat, brush on a little liquid flux and hopefully get much success.
Hopefully it will turn out reusable if it doesn't "wet" like metals. Unless it's totally insulating like the welding mat is intended to be.
>>
>>2774010
You misread me. Most ATmega can run from 1.8V to 5.5V. So can the CH32V003 if I recall.

>>2774032
Desoldering wick needs to wet to solder to work, otherwise the solder will just stay on the board. Graphite does not wet to solder. Would be like trying to use aluminium.

>>2774046
Chances are one of those 360R coils doesn’t exist. If you delete L2, measuring from J1 to J5 will get 360, and J1 to J2 will give 361. If both did exist, you’d be measuring 360 in parallel with 361, resulting in a resistance of 180.5, so either way your diagram isn’t accurate. There could be a short, or there could be one big and one small winding, hard to say. I’d either use a milliohm meter to map the resistances more accurately, or feed some AC into a coil and see what voltages you measure. I doubt it actually has three windings in a triangle like that.

>Desoldering wick needs to wet to solder to work
Capillary action and other such properties of fluid dynamics has nothing to do with wetting which is the mixing of materials in the surface layers to create a strong bond.

It never matters. If it does, you should be using a precision voltage reference instead. Some voltage references like the REF3333 can be used as voltage regulators for low power analogue ICs. They can also push and pull current IIRC.
Your post number is a 1000V diode.

>>2774046
Since L4 and L3 are both really small, I'd guess you're just not able to measure the precise difference between the winding resistance. Build a current source from an LM317 and a 9V battery, and use it as a milliohm meter.
Your post number is that of the CD4046 based PLL IC, even better.

>>2774085
Idk, ever tried getting solder to stick to fine stranded aluminium wire? It just beads right off, even with plenty of flux. Can't see why graphite would be any different.

That part isn't entirely true. You can be killed by an admittedly ridiculous but entirely realistic 30 cups in a day if they're particularly strong and you're particularly weak, but more realistically it's more like 100 cups in just a few hours. Liver disease is a contributor, can't metabolize caffeine effectively. You can also fuck yourself with continuous usage, like one of the Keurig founders who was gradually becoming an hero drinking 30-40 cups daily in their early days. You "can" kill yourself drinking coffee, I just don't know of anyone actually doing it.

They have some serious design issues that male them difficult to integrate properly into a off grid system. Most commercially available wind turbines are also tiny and worthless. You don't start hitting reliable and useful watts until the diameter is at least 10 ft of swept area. I consider 10 MPH to be the most important wind speed. Most wind turbines are rated at 25 MPH. 99% of the time unless you live in a high wind zone, 10 MPH is wat you can expect on a breezy day. You may get more but 10 MPH happens the most often. That means you need a larger diameter wind turbine.

Old water mill style turbines are actually great at producing power reliably. The efficiency is extremely high at sub 20 MPH winds. They get passed over a lot for a couple of reasons, one is your RPMS drop as you add more blades but you add torque. Overall power increases but with diminishing returns. A lot of people will get turned off when they LOSE power by adding to many blades. Its because the rpm drops but the PMA they use has a fixed torque requirement. You would need to rewire the PMA with thicker wire or stronger magnets to take advantage of the extra power. The other downside is above 20 MPH it basically wind walls and drops off. Three blades is great for grid power where you can dump all the watts you make all the time but with a battery, consistency is king. You want 200-500 watts or more all the time, every time it breezes. Keeping those batteries topped off. Availability of power is more important than peak output, especially coupled with solar.
All in all its only for the dedicated off gridder who wants more and you need the land and cleared space. A large farm would definitely benefit.
Some of the integration issues though cost money to fix. First of all you will NOT hook up a wind turbine to lithium batteries. The chance of over charge is to great and they can damage the BMS over time with pulsed and dirty DC output. I will continue in another post. Enjoy my book fags.
>>
>>2773996
So MPPT is needed. This also helps with long wire runs. The other method involves a dump load. You hook up the wind turbine directly to the batteries and when it hits X voltage a relay closes and starts burning off powering a heating element. These are generally cheap but the low voltage of the wire, which is set at your battery voltage means lots of amps and thick wires so expensive if your batteries are more than 50 ft away. I only consider this practical at 48 volts. 24 is a stretch.
MPPT controllers require a voltage sensing brake to keep them from getting fried. Lets say you have wind storm and the batteries enter float, you now have no load keeping the rpm down. The wind turbine will free wheel and the voltage will spike. Potentially damaging the controller. Midnite classic is the only MPPT i know of that supports wind directly and hydro. They sell a clipper but its fucking expensive.
Lightning is also an issue. You want that tower down in a lightning storm unless you want to replace thousands of dollars of power electronics.
I've seen a guy on youtube make his own clipper. He had a simple dump load system. First dump load went to a DC to DC charger. He would directly hook up the turbine to some cheap marine batteries. They would hit some voltage point thats full, and the relay opened activating the DC to DC charge straight to his lithium bank. If the battery bank was full the lead voltage kept climbing to the next set point and the turbine would disconnect and run to his home made clipper. Thats three resistors with a dead short. It would heat the bank of resistors directly with no involvement from the battery. Just an idea. There is a lot to it. You are unlikely to be satisfied by a chinese wind turbine, something 99% of the sellers online sell. Most of the real wind turbine manufacturers are out of business. Bergey is still around but they no longer sell small turbines. Only 10 KW models. 50-60k i think.

>>
>>2774020
It is and by far the cheapest when it comes to dollar to watts. No need to get fancy. Don't let perfect be the enemy of good. A simple 10/12SI alternator with an external regulator and rectifier will last a long time and is fairly straight forward. 24 volts is doable without a lot of money. It also helps with wire runs.
Should be able to do 40 amps max. Some models may list more but the 10si frame is designed around 40 amps continuous. A simple low cost inverter designed around this size and a slightly smaller charger power supply, like an IOTA would help with transmission distance. You could even use a car battery for the hydro since its always going to be topped off. Somewhat inefficient but simple, replaceable and rebuildable with off the shelf parts. Thats a max of about 1000 watts. After losses...Probably 700. Sizing the power supply is the trick, you want it to be a little smaller so you don't discharge the battery.
Golf carts could also be used, giving you a bit of storage room and would let you use a full sized charger. Might occasionally outpace the alternator though.
Other methods involve MPPT controllers and three phase PMA generators. Not off the shelf but a lot more efficient. If your battery bank is not that far away you could just run thick wires to the bank.
