What are the screws on a DB9 port called? #4-40 threads, inside and out.
Guess they are "jack screws" colloquially, otherwise known as "screwlocks."

"During a bicycle race, an elite cyclist can produce close to 400 watts of mechanical power over an hour and in short bursts over double that — 1000 to 1100 watt."

"An average rider can produce up to 200 watts – ride for an hour and you'll generate enough to power a 25 watt fluorescent light bulb for eight hours."

So to get 874 Wh/day
Assuming I bike an hour/day generating 300 W (with efficiency losses)
And 400 W (2 hrs with 2x100 W panels) to 1000 W (5 hrs) from PV system...
Throw in a 1000 W microwave to heat frozen (meal preped) meals for a max total time of 10 min, so 100 W/day.
I think...
Nope. 1200W/60 = 20 W/min → 200 W/day max.
And so a pedal powered bicycle generator could allow for microwave and toaster usage (unless efficiency losses are significant).
1. Food storage
2. Food reheating
3. Miscellaneous electronics charging/usage

What else is there to think about for "urban stealth camping"? (Besides being disrupted or woken up for vagrancy.)

Not overheating in summer
Have a plan for tieing your storage batteries to be charged by the alternator.
but just to be clear, you're using this guy:
as a role model?
Also, use Watt-hours instead of Watts. It's more likely to keep you out of trouble with power.

Fun SNL skit.
I'll be at work during the day...when I get a job. So I'll be fine, but hobby electronics stuff may not fair good in a hot van.

More concerned about if I get a job in Wisconsin. Would really have to look into a quality insulation job for the winter... and would also probably need to keep it heated while I'm away so everything inside doesn't freeze...
A medium roof Ford transit van allows 6" of insulation on the roof and the ability for me to walk upright. s3-prod.autonews.com/s3fs-public/OEM04_303039969_AR_-1_0.jpg
Although, it doesn't look inconspicuous... Wonder what's the worse that could happen...if it can be towed just parked on a public street for a night...
Well, actually, it's more like "in a van down by the [24-hour gym]" ... so just need to clear it with one of the gyms. I'm sure there are some that would allow it.
2017 Ford Transit 250 Van [medium roof] LWB - $17.5k

https://milwaukee.craigslist.org/cto/d/wadsworth-2017-ford-transit-250-van-lwb/7139382325.html

So what, $4k/year. Would be paid off in about five years...agh, but I gotta get a job first!

I know I've seen you're in school, but aren't you working on an EE degree?

That sucks, I was going to take the PE in April
But surely you're not letting that stop you from applying for jobs, right?

I've been applying. Got a whole Trello board for it. Calling employers I applied to two weeks ago, asking about the status of the job as we speak.

Job hunting sucks.... it's potentially a lot of rejection. And the current state of things makes it really hard for some employers to justify new hires
but keep at it. You will get a job.

Ya, even applied to technician jobs in my current city (merely as a place holder until I get hired for EE work).

Plan on it taking awhile. In the meantime, get as much experience as you can. Like this fella: ke4nyv.com/picprojects.htm If you wanted to show off something like this to a potential employer, design it so that they can scroll quickly through - very quickly. They want to see that you have demonstrated skills without (them) reading much at all.
