To build a magnetic patch bay you will need magnetic patch cables..
Below is shown how i make my magnetic patch cables.

Some parts and tools:

• safety glasses! (the copper is springy, and can throw solder into your face).
• thin copper
• small rare earth magnet
• wire
• solder
• soldering iron
• plyers
• ...

Get some small and strong magnets, i got mine from ebay..

Remove the magnet from possible holder.

Cut some copper.

Form copper around the magnet.

Remove the magnet from the copper, because if the magnet gets hot from the soldering iron, it will lose its strength.

Solder inside the copper, this makes it easy to merge them in the next step..

When merging.. try to solder the wire at the same time.

Put the magnet back and sqeeze it in place.. using the round "squeezer".

Cut some copper that is sticking out away.

Put a shrink tube around it and its done..

The cable can be used on nails, a thin etched pcb with metal under it.. or another way...
