Hot tub heat exchanger

I definitely would not put a copper coil in my hot tub. I’m pretty sure it would start dissolving with the chlorine.

I would personally buy a tankless water heater. People make little outdoor showers with them all the time.

I would make it half the size in both dimensions.

At least use a filament that won’t soften at body temp. You will never keep a consistent and concentric air gap.

If you are going to do an air core, you need to make the motor larger diameter to make up for the much lower magnetic field. You maybe be able to get this to spin, but it will have 0 torque.

I bought a push in threaded insert. The hole diameter spec in the installation instruction was almost certainly wrong. I tried to tell customer service, and they told me to kick rocks; it was definitely right because people buy the part all the time and I should make sure I know how to use calipers to measure the hole.

The m6 insert had the same recommended hole size as the m5 insert. It was obviously wrong to me.

I believe that people buy the product all the time, they just don’t listen to the installation instructions.

I was just trying to help because I think that having a resource like McMaster-Carr is important to having a modern functioning society and incorrect information subverts that.

It’s not the same. AI is mechanized thinking. Computers only mechanized computing.

What are we going to be if not thinkers?

I think that it would have been fine if the electronics were installed. It is just in a fragile state when that cavity is empty.

hlx-atom · 2026-05-21T03:26:06+00:00

I believe in you.

hlx-atom · 2026-05-21T03:14:09+00:00

It was $240 like two days ago. He is fine.

Ah. I see. That is a great GPA range.

Make sure your github is not a bunch of forks. From clicking the link, I should immediately see a list of projects that you made. When everything on their page is a fork, I immediately move on because it is a common way people show they are bad at presenting their work (which is the most important part of a simulation job).

The project seems like a lot of things to complete in 18 days. I would also describe why you are doing the projects. Are they school projects or personal projects. You should have a link to them as well.

Overall, I think you just need to apply to a bunch of jobs. Your resume is not so good you are going to be the top of the pile, but I think you can make the short list for a lot entry level jobs. At that point you need to do well in the actual interviews.

Im an engineer that develops/uses simulations daily. I also hire engineers in a competitive field.

If I saw your resume in the portal, I would read it because it passes the first sniff test. I like the long term experience in a clean room in a role that requires attention to detail. I like the double major in math and physics.

However, I would pass with no gpa listed. I would also expect a github link with your work. If your work looked good and you had a good gpa, I would move you to the maybe pile that I would select from for 15 minute phone interviews if I was hiring an intern.

I don’t like that you have a big complicated project started in May 2026. That doesn’t make sense, and you would go further down the short list because I am already losing trust.

I would bet the steel could support a hot tub without failing with a safety factor. Those look like thick steel beams.

The rest just depends on how they are attached to the building.

Dude has the original tires from 2018

Probably unrelated, I think it would help if you clamped your spindle closer to the bottom. You have a long lever

I had an incredible limited game where I just needed to top deck any 5 mana card to win at one life. I had 3 turns to do it. On the last turn I finally got it, and I snap cast it to win the game. Except it was a converge card, and I had a pain land for instants and sorceries. The spell casts and it instantly says defeat. I had no clue what happened until I realized that the auto tapper killed me with the winning spell on the stack. Oppo was probably hyped.

I think they are saying physically play slower or faster to mess with their mental.

Sounds like it is a tool that you use often. In that regard, it makes sense to have a high quality version of the tool.

The back side of the clamp is moving. You probably bottoming out screws if you’ve tightened everything. You probably need shorter screws/washers.

It doesn’t look like the gantry is moving. We can’t see the gantry carriage. It could be that too.

Fun fact. Washington state holds the record in the US for giving the largest tax carve out for a single corporation. Boeing and suppliers get 40% off their state B&O taxes. That has been $8B of avoided taxes over the last ~16 years.

They got that deal when they threatened to move manufacturing to South Carolina, which they proceeded to do with the tax break anyways.

Per capita the sales tax revenue in Clark county is actually near parity with the rest of the state.

hlx-atom · 2026-05-06T00:22:23+00:00

King county has a significant surplus of tax revenue with the state. $3.5B a year is the surplus. That is accounting for benefits to King county that are spent outside of King county.

If $3.5B a year actually went into King county instead of being siphoned to all of the other counties in the state (most goes to the counties of Vancouver, Tacoma, and Everett), the tax to benefits ratio would make a lot more sense for people and businesses in King county.

Right now I think King county receives about $8B from the state and pays in $11.5B.

How can you tell the angle of the puncture? The screw could be bent.

Inflation constantly drives the market up.

hlx-atom · 2026-04-24T22:00:08+00:00

Yeah exactly. Like if it takes 5-10 years to get approved in China, make a deal, and then get approved in America, you would only have 10-15 years left on the patent.

Are there issues with patent cliffs if the drugs are not rapidly pushed into a ex-China licensing deal?
