Copper Band - First Introduction

Ideation

No coding needed: I focus on the pure application in a manageable circuit and inform about my first experience in the use of copper tape. I was critical of the use: only a few examples are available in the relevant shops and except for examples from the field of "greeting cards" were here at Hackster also not (yet) listed.

Step 1

The thin tape was delivered well packaged and coated with adhesive on one side: it sticks well (to my paper) and can be easily cut with scissors. Due to the copper content, the conductivity is given, so I first tested the LED directly with the battery (long leg on the + side of the battery and short leg on the - side of the battery).

Step 2

In the next step, I removed the white tape and connected the blue LED accordingly to the battery. Right away, I did not make the LED shine: only when I wrapped the film tighter around the legs of the LED did a constant voltage of 2.5 Volts flow.

The blue LED is constantly lit and can be complemented with a second white LED.

Areas of application have come to mind for me: due to the advantages of the flattened adhesive tape, a cable can also be routed to a sensor outside a room without a cable being pinched in the door or window (in case of temperature measurement in- and outdoor). Also, the tape is much more flexible in laying than (stranded) cable, so that angled ways are feasible.
