So it's an alloy then? Too bad it's not Ni plated.... But stainless steel works as an electrode right?

If you go to your local welding supply shop they may give you a sample of Ni welding rods. These are (I presume) pure Ni. I obtaineda bout fifty 3 mm
by one 10 inch long rods this way.
You can of course purchase

So Ni is really needed then?

I don't know if Ni is actually needed. Would not carbon rods do too. They are available as gouging rods.
The cathode can be made from just about any metal as it will not corrode. The anode must be non corrodable in the KOH solution. If Ni will do I would
think that other relatively inert metals would do as well, stainless steel being most easily available.
Valve metals (Ti etc) will not do as they will not conduct electricity when used as an anode. OK for a cathode.
Would a great big piece of carbon fiber cloth (if you have any) do the job. Is the stuff conductive?
The drum of a washing machine from the dumpster sounds good to me.

KOH is just the electrolyte right, can't you use something else, NaCl, ect.

Using NaCl will electrolyse out the chloride as chlorine gas which may damage your device or autoignite the oxyhydrogen mixture (although I have not
seen this listed as a warning anywhere?). Since it is aqueous any group 1 metal like Na or K will do for a cation but the anion should be something
like hydroxide. I believe carbonates will also work fine?

I heard that O2 lessens the likelihood of Cl2-H2 to autoignite, could be wrong though.

Was looking up information on buying one of these the other day, I was wondering how hot they get since the electrolysis will not hit theoretical
output and found this video:

I found it of course because I was searching for HHO after Bfesser's reprimand of another member for crackpot science. Back to the video though, they
sell these small generators for 'acrylic polishing' on eBay and this was the only video I could find on one in action. Of course the brain trust that
shot the video decides to test the mettle of the flame against the might of thin plastic, wood, and a digital thermometer (for food it looks like)
that goes up to only 300C. It's sad really.

Lol, the guy says "The flame is not really burning, it's just recomposing into water".
He also says "you can use the flame to heat your house".
No but really, it looks like a very good replacement for a propane torch, I would buy it if I could.
Don't use it to heat your house though.

This is my first post, so wish me luck
I don't know much about this subject but have built many many hydrogen cells and eventually settled on a dry cell, a 6-7 plate dry cell running at 12v
and a current density of less than an amp per cubic inch will have a reasonably high gas output and be very very efficient in comparison to a wet
cell.
This is a link to a video about a cell and torch I made about a year ago.
