Hello,
I have been messing about with electronics for years, mostly in
connection with ham radio.
A few days ago I was doing something with some 'paper fasteners'. These
are small brass things with a head a bit like a small domed nail and a
body about an inch long which is split. One pushes the fastener through
two or more sheets of paper or card and splay out the split body to hold
together the card.
It occurred to me that these things, or possibly brass drawing pins
(thumb tacks to you yankee types) could be used for making circuits in a
slightly larger surface area than a circuit board or matrix board.
I have tried this today. Pushing drawing pins into a scrap of wooden
board, or pushing the paper fasteners through a couple of sheets of
scrap corrugated cardboard they form little 'islands' of brass to which
it is quite easy to solder wires or component leads.
They can be pushed into or through the base board in a pattern that
facilitates the circuit.
In the case of the paper fasteners, be careful in splaying the split
body on the back of the cardboard, not to short one to the next and so
spoil the circuit.
If you use the fasteners, once the circuit is complete you could glue
another sheet of cardboard on the back to completely cover the reverse
ends of them.
This is also a good way for you to introduce electronic circuitry to
youngsters or beginners in electronics.
