Not likely but ther eis anotehr totally different problem, asymetric noise
pickup masking the cores switching.
I hadn't thought of that. Good point. Another problem is that "worst
case"
diagnostics won't necessarily be worst case anymore.
You're further ahead fixing the mat.
Sigh. It looks like *quite* the challenge.
The wire used should present little trouble as fine
wire can still be had.
Any idea how to estimate the gauge? I know I'd need red and green enameled,
perhaps another color like yellow? I also wonder what they used to insulate
the splices? It appears to be some kind of paint.
As an aside to this with the lamers trophying the
mats. Most often the
mats are intact so someday they could again be spares.
True.
The best one I've ever seen was not real but
instead used small nuts and
three colors of wire to make a real looking mat of some 64 or 128 bits.
What size nuts?
I'd bet that with the right currents and timing
you could even store data
in it.
Oy! The core circuit that I copied for my 12th-grade drafting project used
7.5VDC as the half-voltage. How much oomph would it take to induce a stable
magnetic pattern in a steel nut?!? I would think that enameled insulation
would cook right off the wire.
Anyone with a EE degree and a copy of Spice care to take a stab at it?
