[sdiy] Latest find: Unusual pin matrix

[john mahoney]

My first thought is, "It's worthless, but I'll give you 10 bucks for
it." ;-) Naturally, I would use it for an EMS style matrix.

This is like a dual pole switch. (The single layers act as SP
switches, of course.) Too bad you only have one dual layer pin.

New pins could be made -- if you are good friends with a machinist! Or
maybe it could be done by hand. Key would be finding metal tubing of
the exact diameter. Use the tubing for the conductive outer parts, use
a central pin for strength, and hold it all together using epoxy. I'm
saying this withouth haveing seen the pins, though. </brainstorm>

Pardon me, breakfast is ready...
