This newly designed Polypanel allows you to lead two wires through the panels connectors and have power to let lights glow or else without the tangle or clutter of wires all around.

The panel is designed to have continious wire lanes runing on all sides and with only one battery in the center no shortcuts should appear.

With pieces for batteries and lamps it could become an educational Set for understanding electronics and small circuits.

For best connection unisolate the wires, push them into the hole from the inside of the panel, put a piece of solder in the hole to touch the leads and grind lightly proud to the surface.

For me it worked best with 200% scale.
