[sdiy] Banana vs. 1/4" question

[Grant Richter]

Not dissing bananas, but they do cost at least a quarter apiece.

Has anybody got an idea for a really cheap connector?

Like for a circuit where 5 banana connectors cost more than the circuit
underneath?

I don't think the springs like they use on the Radio Shack experimenters
kits would work.

I sort of have an idea, but only if I can figure out a really inexpensive
connector. Like maybe a PC mount socket lined with wire brush that you could
just shove one or more solid wires into for patch cords?

The circuit is absurdly simple, but produces mathematically complex results.
Possible useful as an electronic music module, but it couldn't be
manufactured unless the connector price was like a nickel each or less.

Any brainstorms appreciated!
