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 did you have plugged into the outlet? It's not going to blow a fuse with nothing drawing power, unless you have a fucking 16 amp resistor soldered between the line out and the neutral bar.

Hello, building people
I think I goofed up the finish on this end table by putting a PIPING HOT ear of corn on it.
I wrapped it in a paper towel, but it seems the heat was too much
What can I do? So I, like, sandpaper it and put more whatever back on?
I know very little and am kinda dumb, please help.

Question related to issues with my detached garage:

The first thing is that the slab the garage is on is in horrible shape. There are cracks everywhere, large chunks missing, exposed aggregate, etc. Is this something that is repairable in a DIY situation, or would the slab need to be broken up and removed before a whole new slab is poured? I don't know a ton about concrete work, but to me it seems beyond saving.

The next semi related question has to do with moisture. The plywood on one side of the ceiling in the garage is always wet. Like completely saturated with water and drips a significant amount on my car. It's only the north side. The south side is totally dry. I originally thought it was the roof so I had a new one put on. It continued staying saturated and dripping so I called them back to look. They lifted the shingles on the garage, and underneath the felt paper and everything is bone dry. They redid the cap to face the opposite direction in case it was wind/rain related but that made no change. My thoughts are that water is seeping up through the cracks in the slab when it rains, evaporating, then forming condensation on the ceiling of the garage. The slab is definitely damp so I think this may be the issue. Since my slab is in such horrible shape, if it's beyond saving could I at least put some sort of sealant on the floor to try keeping the moisture out, or would that be a waste of time?

This isn't my forever home and I'm planning to use it as a rental in a couple years. I'm unsure about how much money I really want to put into it at this time.

if you want cheap then you do not need whatsoever any hydraulic anything to shear or bend 1/8 aluminium, look at manual box/pan bender and shears for making boxes.
there are lots of configurations you can make at home with scraps, depends what you have lying aroumd

I'm thinking of buying a solar setup because of the frequent power outages here.

Here's a picture of my KWH electrical usage.
I was burning wood Oct/Nov/Dec but had to run out of province so I just left the baseboard heaters on while I was gone for a couple months.

I'm thinking of getting EG4 3kW Off-Grid Inverter and one or two EG4 LifePower4 Lithium Batteries to start. How many Solar panels would I need to have this setup work if just to keep my well pump running? I'd like to potentially run my Starlink and computer too.

>>2793960
Oof. Well pump.

I worked the following out for a fren who had a 250ft deep 3-phase.

Many such options, but I'm going to give you the cheap one, first:

Get a 2-5000 gallon surface level (just put it on the ground) tank. They sell these all over the place, tractor supply, etc. You should have no problem sourcing it.

Get a single-phase pump that will provide enough pressure and volume to your dwellings/barn/hydrants, from the tank. Get a UV lamp for the outlet of the tank as you like. Feed that pump from your EG4 3k and 10kw of batteries.

Replicating 3-phase power is possible from a single phase setup. Look into that, too.

Essentially I suggested that he have a system that when the mains power was out, and pressure dropped at the accumulator tank (bladder tank), the contactor would power up the single-phase pump and feed it power. Obviously, it would give him water until the reservoir ran out. But it should last him a week.

>>2793960
Get 2, not 1 EG4 lifepower 5kw. You need 200ah to operate that unit correctly. I have the Growatt version, but I'm sure the requirement is the same, because of the limitation of a single EG4 5kw/100ah cells & BMS.

The capacity of the 3kw inverter will trip the breaker on a single 5kw EG4 (and probably any other 100ah too). Plus, you'll pay the same shipping for 2 as you would for 1.

Davidpoz used a pair of batteryhookup 24v modules, $699ea + shipping, for $1500, 90% capacity, 280ah cells. BMS is from Orientpower, called DIY BMS, $363. 'Build your own solar battery, fast and cheap' is tbe video. That would give you more than 2x the capacity of 2x EG4's, at 2/3's the cost.

And again, as he said you can order something like 16 of those 24v banks at a time, and pay the same shipping as for 2. Essentially all those batteries come on a pallet, so you're paying for the pallet, whether it's 1 or a dozen batteries. My total failure of understanding everything I wrote above, at the time, meant I had to eat the shipping cost for a 2nd.

>How many Solar panels would I need to have this setup work if just to keep my well pump running? I'd like to potentially run my Starlink and computer too.
well pump: likely very little solar panel wattage, because despite their high power draw, well pumps don't usually have much "on time"
They normally have a diaphragm tank to act as a buffer. My well pump uses 1500w when it's running, but it pumps about 12 gallons a minute, and our usage in a day never exceeds a few hundred gallons at the very most. For me, that would mean a single 300w panel would probably cover my needs.
The bigger issue with well pumps is that most conventional pumps have a huge start up current; they might use 10kW or more for just a couple seconds when they turn on, so unless you have a soft start or inverter drive pump you'll likely exceed the surge capacity of your 3kW inverter.
Furthermore, most of the cheap off grid inverters (I haven't bothered to look up the EG4) are transformerless or "high frequency" which further limits their surge capability compared to the heavier units.

In many cases it is more economical and sensible to swap your pump to a soft start pump (like a Grundfos SQ) rather than coping by using a much much larger inverter. This saves you a lot of power use every day because the larger the inverter, the larger its standby or idle power consumption will be.

As far as your PC and starlink goes: consider their average power usage over 24H then consider your worst season solar irradiation (look up a chart) and figure out how many kWh/day to expect from a given wattage amount of panels. You'll get your answer. If you intend to remain connected to the grid for backup/low times then it may be more sensible to have a best-effort solar setup that takes care of your needs 90% of the time rather than building a system twice as large to cover 100% during the worst solar times of the year.

>>2793976
its usually cheaper and easier to swap to a soft start pump

>>2793992
Pulling a pump that was 250ft deep was a significant cost, aside from the pump cost. How much does the Grundfos SQ run?

What's the cost on a converter to make sufficient 3 phase power to power the pump from a single-phase source?

The oak in my back yard made a pretty decent hammer. The pecan tree contributed the handle

>>2792904
Where can I find a functional giant barrel hammer? I want one like kirby or mario.

a 20oz estwing with a straight claw and no waffle is my favorite general purpose hammer. I wouldn't mess with wood handles unless I swung a hammer all day.

>>2793063
i have never bought anything heavier than a 20oz.. sledges and drilling hammers just seem to always appear out of nowhere and I just fashioned handles for them as I needed them

>>2793688
I have lots of hammers, and arguing over what's best is pointless as so long as it's a sufficient quality it's all user preference. Mostly use a Vaughan 999 or DO20, and a Picard latthammer. Sometimes I breakout a 100 year old Maydole straight.

>Go ahead and explain why it's so expensive.
Same as anything: parts and labor. If you think every HVAC contractor is gouging on every job, then that is what normal people see as a golden business opportunity. But it isn't, or someone would already have taken advantage of it. That's why I say you are full of shit.

Yes, it seems outrageous. But buy a truck, buy equipment, hire help, pay expenses, and see if you make a killing. If you do, wonderful. But when you don't, you'll see why it's so expensive. It isn't like dentistry or any other racket where the bar to entry is so high that it might as well be a cartel. Anyone can start an HVAC company if they can get a license, and someone as intelligent as you can get the license. So why don't you want to do it? Because blah blah blah but at the end of the day it's because you know you are full of shit.

now it wont go below freezing.

>>2793955
>Anyone can start an HVAC company if they can get a license, and someone as intelligent as you can get the license
In my state you have to have 4 years of full time working for someone else who already has a license before you can be eligible to get your own. Taking an approved college training program reduces the requirement to 3 years.
It's normal for the contractor to make hundreds of dollars per hour in profit. It's just restricted enough to keep competition from driving prices down, while being just loose enough for rednecks to stay in business.

it was certainly a good deal
the performance is quite good too once you read the manual and really get to know the radio.
Speaking of you know anything about using electret elements with a FT1000MP? guy gave me a heil headset to go with it but the main element needs power and the dx element is just a dynamic.
Was reading that I could put a resistor from pin 2 on the connector to pin 8 to supply it but couldn't find anything about what value to use.

I really wish he would have given a better explanation for how the integratron works.

>>2786882
Yup. He claimed it was possible with a type of high-speed switch that hasn't been manufactured in like a hundred years. I think I understand what he does with it, but he's really bad at explaining everything.

>>2793629
I would like to clarify because I was _nearly_ correct. (I was wrong)
If it does SSB it will do CW/FM.
If it does FM, It probably won't do SSB. (I was wrong, if it does FM, it will likely do CW.)
Hope that clears things up.

You'd have to read the code to confirm that.

Have you ever just wanted to choose the most esoteric and obscure MCU for a work project so that you have more job security? I've been tasked with designing an internal prototype as an intern. I'm supposed to design the PCB and also write firmware, and two MechE students are designing the enclosure and doing some simulations. The company is a startup and run by MBAs. I want to get hired again after graduation.

I think internet without paying for an ISP is possible, but it would require changing the way the internet works. It would require a new device that produces a very long-range directional beam, so it would only be able to communicate with any other computer that has the same device, and only one at a time. I can't really think of any way around this.

That's not the internet, it's packet radio.

>>2790879
the internet is just other peoples computers
you pay to use the infrastructure that someone else has installed to connect to those other computers.
big infrastructure companies have agreements to connect to each other for no charge because it benefits them both.
if you had some awesome web service that customers would literally change isp in order to use, then all the isps would offer to connect with you for nothing in order they keep their customers. thats basically it.

Those small HVLP sprayers are nice, they waste less paint and are easier to clean than an airless and have way less overspray than a traditional spray rig...plus what it does make is less likely to stick.

Pretty easy to control the pattern and once you have one you'll find plenty of other uses if you havevyour own place that needs maintenence or even do stuff like refinishing furniture.

Especially if you have stuff like fencing to do its money well spent.

Just buy a cheap pump up sprayer its low pressure have someone back roll with a 3/4 nap roller
Thank me later

>masking the other side
You're better off in my opinion just stapling vapor barrier on the other side with a hammer tacker. The cheapest non-code plastic film is like $10 for a 9'x100' roll. Making tape won't hold much on painted wood, and it might just fly off with the gust of air from the sprayer. Even less work if you can have a helper, like a family member: have him or her walk along the other side and hold a large panel, whether it's a scrap piece of plywood or a bunch of real estate signs attached together. You just want the overspray not to fly off. As soon as it is disturbed by something in its path, it falls off very quickly and will not go far. Obviously wear work clothes as you and your buddy will get some overspray.

>>2793872
There's a commercial brand available in store that is DeWalt compatible. It's at Home Depot I think. But if you're worried about cords, you should know that anything cordless is usually a lot heavier. On a ladder, you can tape your extension cord to a rung and let a few feet hang for the sprayer. If it holds more than a liter, just don't fill it as much. There is typically no minimum volume for it to work, except for one thing: the pickup tube is typically angled so it will keep working when spraying upwards OR downwards, but not both. You decide to point the pickup tube to the front if you intend to spray downwards or to the back for upwards, but it matters only if the reservoir is running low.

Those look pretty nice. The problem is, they’re all fairly expensive and like every single brand has started to sell them but they get pulled from shelves within a year.

If you’re doing a one time buy, go Toughbuilt or Klein or Flex or whoever has the best prices on the setup you like. The Klein might be around for years, but it’s brand new and so many of the brands sort of flopped and disappeared from stores. Ryobi came and went, Flex was like a seasonal display, I think Skil has em on Amazon.

Milwaukee seems to be the one that is going to stick around. The Ridgid boxes have been around for awhile too, but more limited options. And DeWalt’s has been around for some years as well but not as popular, plus I think some Craftsman boxes might fit the DeWalt stacks.

If it were about the same price between Klein and Milwaukee Packout, or even if the Packout was like $50 more overall for the whole set, I would take Milwaukee.

There’s reviews comparing them online from a few dudebros.

>>2793966
I looked at several videos and articles and it looks like toughbuilt and klein are the best build and have the best features. I already bought one triple drawer box klein box and I am waiting for the drawer version of the rolling bottom end.
