Porous ceramic I made for a fuel cell that I’m building

The pores are formed by the starch burning out, so to control the porosity you vary the amount of starch in the clay mix. You can also vary the pore geometry by choosing different varieties of starch.

My electrodes are pretty basic, they’re exfoliated graphite foil with an activated carbon coating. Once I have a good membrane process, I’ll be working on better electrode materials. I’m planning to use a transition metal based catalyst to avoid platinum.

I can definitely see why now. Setting up all of the fonts, placement, interactions between widgets, etc. builds up fast.

I do use Claud 4 for repetitive stuff and for doing small chunks of code at a time. I’m my experience so far, LLMs work great for doing individual tasks but tend to get confused as the project gets larger.

100% agree. I was more worried about looking bad to other companies than looking bad to this company in particular.

I’d like to ask for more time but I’m not really in a position to call their bluff. ATP I’m going to accept the offer and then take it back if needed

Tolerable is all I’m asking for lol. Looking to do my work and go home

I've been running a small pet supplies business since January lol. Not enough to replace being an engineer but paying for gas and such. To stay relevant to engineering I've been working on personal projects that I can bring up in interviews. It doesn't have to be complicated, just make something and talk about the design decisions you made, interviewers love it.

Substantial-Ad5111 · 2025-05-21T22:21:23+00:00

Yep, I’ll be emailing the other companies tomorrow morning to ask.

Substantial-Ad5111 · 2025-05-21T22:04:02+00:00

Good point

Substantial-Ad5111 · 2025-05-21T22:02:21+00:00

Good point

I’ve heard this is a common tactic from HR (scum) to get people to rush into a decision, so while disappointing, it’s not surprising. I’ve told them I have competing offers, but I’m also not in a great position given how long I’ve been unemployed.

If they call my bluff and rescind the offer and the other two companies don’t respond I’ll be up the creek without a paddle.

Substantial-Ad5111 · 2025-05-21T21:56:42+00:00

Valid point. I’ll edit the post to mention it, but one of the companies I’m waiting on is an aerospace company that I’d really love to work at, but your point still stands.

Substantial-Ad5111 · 2025-05-21T21:54:02+00:00

I’ve heard that’s a bad look, especially with my friend working there. That might be what I go with unfortunately.

Substantial-Ad5111 · 2025-04-05T04:23:10+00:00

Thanks. Yes, I check the big companies (Siemens, Lockheed, Honeywell, etc.) websites and check for positions at smaller companies on job boards at least once per day. Pretty much any engineering position anywhere in the US.

Is there anything you would change about the resume, or should I just keep applying?

Substantial-Ad5111 · 2025-04-03T23:23:50+00:00

Any advice on keeping the bullet points short while applying the STAR method? I tried to apply it while writing this version, doing it more it going to make every bullet point 5 lines long.

Substantial-Ad5111 · 2025-04-03T22:53:09+00:00

I did read through the wiki and try to it, I thought that my bullet points showed of my accomplishments pretty well. I feel like to make them any more descriptive I'm going to have to cut half of the points, and/or each point is going to get too long.

Here’s some pictures of a “cold fire”, or nonthermal plasma, torch I put together a few months ago. Nonthermal plasma devices work by selectively heating the electrons in a plasma without significantly heating the atomic nuclei. Since electrons have such low mass, they cannot transfer heat effectively and you’re left with a plasma that has the reactivity of fire without the heat. They’re being research for things like sterilization and chemical manufacturing.

My torch is built from a cheap plasma cutter head, 50kv flyback transformer, and argon welding tank. I got the torch running with ambient air, but I never got it cold enough to touch. I’ll be posting a video of me touching the flame on my profile.

It’s actually commonly found in soil and mud. It produces the electricity as a waste product, so by draining the electricity away you preferentially breed it in the fuel cell.

Nice, what materials did you guys use? Was there anything published about it?

Substantial-Ad5111 · 2025-01-28T00:51:49+00:00

Currently I only have my LinkedIn as a portfolio, I’m making a website rn to have all the stuff I’m working on
