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!

This guy is putting himself at incredible risk. There are probably so many CEOs and sales managers that want him dead right now

Does anyone know if any of these blue collar companies have hinted at trying to threaten him yet?

Todd compares tools and electronics from various companies using elaborate expensive tests. He's shown people that more expensive items are not always the best and that sometimes companies will sell you shit that does not even work. Many a contractor watches his channel. He refuses all sponsorship so the companies he mentions have no choice but to mald in silence

It steers creators to quickly and continuously pump out content which makes the content suffer in quality.
This is exactly why you get half baked tests out of him.

Guess that's not enough current then. I'll try 10k series resistance, then 1k. About 0.5V was being dropped across the solution with 100kΩ, hope it doesn't increase too much, as going too high increases the chances of making chlorine gas.

How do I go about fixing a board like this? When powered, it doesn't light up until the room it's in is above say 75F, and then it's only half of the board. When it is 80F+ ish, the whole thing lights up. Wat do?

Perhaps take a hair dryer and gently warm parts of the board to narrow down a problem area. This includes the power supply.

Here's something to try if you have no volt meter or multimeter.

Firstly, are those printed number or are those two dots adjacent to the LEDs pads with continuity to the LEDs?

If they are pads and not printing on the board, use a wire jumper or a metal tool to short each of the LEDs one by one. If one LED has an open condition the other LEDS will light when the bad one is shorted. It might reveal an LED with a poor solder joint or an internal failure. This assumes the power supply is working.

An alternate way would be to check the same points with a volt meter. An open LED would show full supply voltage and the other LEDs would be zero.

Found this object in grandpa’s tool chest, and I’m at a loss trying to figure out what it is. Says “not for impact use” on it. What is this thing?

You’re going to tear up the edge of that velcro backing pad real quick and it won’t hold regular 5” discs properly in the future. You would be much better off spending $10-$20 on the right size ones instead of ruining part of the sander.

Keeps getting restuck. I rotate it using an Alen wrench, then it hits something and stops. I back it off and then I can rotate freely. But as soon as I turn on it freezes up again within one or two rotations. ( all but instantly ).

I can find anything I’m there to remove. It feels a bit like metal on metal and I’m wondering if it is just broken.

Garbage disposal? Sanity check, are you sure there's no utensils or anything else that fell down the drain? Maybe something on the counter that might have fallen in? It doesn't have to be big to lock the thing up. If a bearing or something internal to the motor was wrong I think it would make a lot of noise and not just lock up solid.
>>
>>2446245
I’ve cleaned out the the disposal I can’t see anything else In there. I’ve done this maybe 50 times. I get it rotating, run water to clear it out. Manually rotate. Then it catches on something.

I can’t see what. Trying to look down with flashlight don’t see anything like seeds or anything that could be getting caught. Once it is “clear” and rotating it is fine for a few manual rotations then it locks up again.

Back again with a couple more questions. Pulled all the carpet up in the living room and the back half had an addition put on at some point. there's a difference in height between the two subfloors, and the difference isn't consistent along the entire length. The addition is about 1/2" higher on the left side, pretty flush in the middle, and 1/4" higher on the right side. Whoever installed the carpeting used shingles along the gap to gradually bring it up to flush in the areas where it needed it. How can I go about correcting this if I plan on building up the subfloor and using vinyl planks as my new flooring? After I'm done can I run a belt sander along the seam and kind of feather it down to match? Should I use shingles or something similar again?

Also, is OBS okay to use as a second layer to the subfloor? I'm trying to do this pretty budget, and OBS is about half the price.

>>2446386
Practice welding. Or use them as rods to hold together wooden box-type projects that you want to easily disassemble later. Or bend a couple into hooks, thread the other ends, and screw them into poles to make grabby-sticks, or into boards for hanging things. Or insert them into parallel boards to make drying racks for shoes, etc. Or cut into short pieces, drill holes, and thread cord to make necklaces or dinky wind-chimes to sell to your sister's art-ho friends. Or make lethal bolts for your homemade drill-powered automatic crossbow:

Or the obvious answer, sounding rods.

Is there a /diy/ solution for a cat shitter? My main contention with doing it manually is it's another thing to keep track of, and I'd rather buy a bandsaw instead of spending $500 on a consoomer cat shitter.

I had pretty good success with the ones that are a round, rotating basin with a grain elevator-style ramp. They're fantastic when they're working, but the motors burn out too easily. I eventually gave up, but if I were going to DIY this, I'd either try to recreate that design with more robust materials, or buy another one and swap out the mechanical guts. Gear something way down to low speed/high torque.

They’re not some hard plasti that shatters when dropped. The indentations and how they’re affixed matters much more than dipped vs some big dual material.

Absolutely do NOT do this. It has precisely zero health benefits, and often leads to countless health problems down the road, not to mention a ludicrously high complication rate. I nearly lost my younger sister because my parents decided to circumcise her. I don't care whatever your beliefs are, people are born with their genitals intact for a reason. You wouldn't cut off your daughter's toes for the hell of it, so don't fuck with her genitals either.

From 40 CFR Part 82, Subpart F, section § 82.161, Technician certification:

"Any person who could be reasonably expected to violate the integrity of the refrigerant circuit during the maintenance, service, repair, or disposal of appliances (as follows in this paragraph) containing a class I or class II refrigerant or a non-exempt substitute refrigerant must pass a certification exam offered by an approved technician certification program."

The law also says that it is a crime to sell or distribute non-exempt refrigerants to someone without a license, which means that unless you synthesized your own-- there is no legal way to get ahold of the refrigerants. There are exceptions for things like propane, water, nitrogen, carbon dioxide, and also for certain quantities and types of refrigerants for motor vehicle use (hence the little cans of r134A at walmart)

That being said, obviously there is nothing stopping you from illegally buying r22 or r410a on ebay or amazon or facebook marketplace. And the government doesn't meaningfully enforce these restrictions on sellers like those.

Even though tankless water heaters are theoretically more efficient in terms of energy usage, the amount of energy saved compared to a conventional tank water heater is minimal, and you will not save money on energy costs over the lifetime of the heater compared to price difference that you will pay for the tankless upgrade.

The most common situation that makes tankless a good idea is if you have enough people trying to shower or bathe in a small enough time period that you're having problems with running out of hot water from your tank heater. Imagine having 6 people all trying to get hot showers in the morning before going to school or work. If you never run into that issue, then it's not a problem for your household and you will likely lose money by switching to a tankless unit.
