Tony seems like an informal kinda guy!
That depends one what I am being 'formal' about. I am 'informal' when it
comes to clothing, tidiness, making a quick kludge-circuit to get
somethign done, etc. I am 'formal' when it comes to attempting to
completely understand something (what i mean is, I will not skip over
some part of a cirucit because it's 'obvious'. Often such bits are the
real key to the workigns of the device in question), or when I am
designing soemthing that is goign to be usef many times or by others.
aAnd I guess I am 'forma;' when it comes to elecrtical safety. Yes, I'll
work on high botlage stuff. Yes, I'll work with the mains. Yes, I'll work
with CRTs (and worse). But I will not leave off earth wires, or short out
fuses, or anything like that.

I think I've worn one exactly once in my life (to get my first degree,
univerities expect things like that, and they can refuse to grant the
degree if you don't comply).
You mean
you don;'t have a bench supply???
Well, I have some orphaned in-line or
wall-wart supplies intended for
computers, radios, etc. that I could chop the connectors off of. But
I figured the jump cables could put out more current.
A somewhat bulky, heavy, relatively high capacity 12V supply, that has a
built-in petrol powered charger, and is not only on wheels for moving it,
it is self-propelled. That makes it readily movable to alternate sites,
and can even be used for moving the whole thing to a petrol dispensary
when the fuel supply needs to be replenished. Although the guvmint
regulates transporting it under its own power, there is little or no
regulation of what you can do with it while stationary. It has seats, not
quite like a Cray, that are even enclosed (with windows) for inclement
weather (some teenagers re-purpose it as a romantic assignation). It has

tools. It has a radio

although not as readily aimable as would be nice. Those worklights can
also function, when removed, as an excellent dummy load. Although it

could easily be modified to run on the hydrogen that
it is capable of
producing, unfortunately, the efficiency is too low for it to produce as
much hydrogen as it would require for sustained operation.
Well, if you can make a system which will burn hydrogen in an engine and
use the resulting mechanical otuput of said engine to run a generator to
electrolyse water to make hyrdrogen and if you end up producing more
hydrogen than you burn, a lot of people will be very interested.
