Its a nice place to learn, very much unlike reddit.

The best thing about this board is that the conversation stays polite and people can agree to disagree if needed. But everyone except the very few and far between can learn something.
Reddit has some intellectuals but I find the majority to be dismissive and lack knowledge I saw one solar installer on there yesterday flat out say there was no solar panles above the 50v range slagging off gpt for false information. I know chat gpt isn't great but in cases like that I'd take its information over some closed minded luddite.
The great thing about this forum is you tend to get more detailed answers with scientific backing rather than just yes/no, I much prefer to get an answer like "you can't do that because...."

Hidden in these sentences is a parts list and wiring diagram, but it's not obvious to me. Could a smart person help translate this into something a preadolescencent like me could actually build?
Is it something like this?

Gas discharge tube... on both lines... the small ones are 3 plates with a gap filled with an ionizing gas. The center plate is ground, the outside plates are the two wires. If lightning strikes the gas ionizes and there is a short to ground and between the wires. These are usually destroyed in one strike. They also make larger units that are single conductors and just a wire in the middle and a foil strip down the sides. These are shaped like two cones back to back. These are used in 1000w radio transmitters and are as long as a foot.
TVS diodes just have a breaking voltage that is high, 70v, a hundred, several hundred. When the breaking voltage is exceeded they are a short. So lightning strikes and the short the voltage to ground. You can use other components to set the break point very precisely. They will clip voltage spikes to ground but if the voltage exceeds their capacity they melt.
So you stack these with a MOV and one clips 300 to 500, the 500 to 900, then 900 and above. These are sample voltages but you get the idea.
My point is that the midnite SPD are very probably worth the price they charge. Sure the components are worth half that, but you could buy one and just wire it together.
What I don't know is what if any frequency component there is to lighting. The circuit board runs would take that into account with run width and thickness.

You were in the Navy... I know dog gone well you have seen worse!
I closed my eyes, put my fingers in my ears and drank heavily when the old sea dogs started telling stories of what they used to do with the girls when in the PI. Some of those were just gross and the girls would do anything for cash.
Mostly just for the LoL's, yeah, but it's real. I had to move the 200A live panel to... something. I started at 10pm, Sawzalled the stairs out (trapping myself), moved the panel like 12" to fit the stairs, and finished the landing at 6am when my 8-month pregnant wife came home. DIY Solar isn't my first foray.i am guessing you are in the middle of remodeling that space and have decided to spin a few members up here with the photo
Eventually I hired an electrician to rewire the entire house, and a friend to make the basement pretty before we sold. Before 'n After!
It looks less like a building site but no boards on the ceiling and a floor that looks like it was troweled by Stevie Wonder I wouldn't call pretty

Sorry OCD, I tend to self level and epoxy all my workshop floors, i had a flagstone floor in the basement of my previous home although it was "pretty" I'd made me sick looking at it.
Bonus that you still have to pay for isn't really bonus, a few bags of self leveling compound would have fixed the unsightly gaps under the skirting. If your flipping a house it's fair enough but if your aim is to spend the rest of your life in a property things that aren't perfect tend to irritate, that's my experience anyway.

Your next ken... I was an oil engineer for years I'll be picking apart your waste oil burner piece by piece

thats great actually, the more critique and input the better the chances of sucess.
Waste oil burners have always interested me for shop heating, but a boiler is different, and I have no actual experience with something like this.
I wanted to use a high pressure fuel pump to atomize the waste oil through a nozzel. dual spark ignitors with a photo sensitive eye to send a signal to a timed relay. no signal within 3 seconds of ignition start signal and the relay will open shutting the pump off and resetting the timer. a squirrel cage would provide the needed air flow. A honey well aquastat would provide the temperature control signals and as they are a pre-existing module that has a proven track record that part is already in the bag.
the guy in the states I am working with uses high pressure air to do the same without the fuel pump (gravity + syphon feed) but his are all manual light off for use in DIY foundries.
he has videos of his units hitting some serious BTU's melting steel in a home foundry along with other feats of mayhem.
hoping to combine both of our experiences to make this work.
Point taken, and totally agree. But, when you're losing $100k on it already, you become reluctant to invest a whole lot more.It looks less like a building site but no boards on the ceiling and a floor that looks like it was troweled by Stevie Wonder I wouldn't call pretty
It's also an 1895 structure with nothing level or square, so at some point "better than the last guy left it" becomes the mantra.To bring in back to solar
, the only place it could have taken panels was on the Model-T garage, which my freaky neighbor would have fought tooth-and-nail!
