There are plenty of stuctures you can build with glued playing cards that

But if you're just learning high speed
don't matter, even with full
computer prototypes. Incidentally, I just saw this:

Okay, I know that some folks assemble jigsaw puzzles and glue them to
a substrate when finished so they can be used as hanging art. And I
suppose it's possible to glue playing cards together in case one
wants to prove that he built an impossibly huge structure with them.
But how does one preserve this kind of thing constructed on a
wireless breadboard? Pour potting resin all over it? Put it under
glass?
Do not putt potting compound on it. It's almost certain some will 'wick'
into the contacts and cause them to go open. It'll never work again.
The best way to preserve it is, of course, to solder it up on a bit of
stripboard.
I remember my dad showing me that he still remembered how to
breadboard--on a nice piece of shellacked pine, using 14 AWG sold
copper wire and UV201A's and plenty of woodscrews. It was a thing of
beauty.
You really do want to read the 'Impoverished Radio Experimenter' books.
You still build real bradboards in there, valves in screew-termianl octal
relay sockets, home-wound coils, etc. Oj, bnt you do ahve to solder some
of the connections :-)
