Paper Circuits: Alternatives to copper tape

Copper tape is the go-to tool for making paper circuits. There are alternatives to it though. Here are two that can be used to circuits on paper:

Circuit Scribe Pen

This pen is filled with conductive silver ink. It has a rollerball tip that dispenses the ink smoothly. You can draw the circuits and attach LEDs just like you would on copper tape.

Bare Conductive Paint Pen

You can apply this conductive paint much as you would glue. Create lines and apply circuit stickers or LEDs.
