Upcycled PCB Earrings




Hi it's aardvark! Here's a great project to make a beautiful piece of jewellery from a pre-loved circuit board. If you have trouble parting with an old electronic device this is a great way to keep a memory of it.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials:

You will need:

  • 2 silver jump rings
  • 2 silver shepherd earring hooks
  • 2 earring backings
  • a black marker (not permanent)
  • a beautiful PCB
  • tin snips
  • sandpaper or Dremel tool
  • superglue (optional)

Note: Do all cutting and sanding in an open area with appropriate protective equipment. This is because your lungs may be exposed to carbon dust.

Step 2: Marking

With a marker, mark four rectangles of the same size.( I have used permanent marker to help you see my outlines.) There are four rectangles so that you can choose the best two.

Step 3: Cut

Cut the circuit board with tin snips along the lines you have drawn.

Step 4: Sand

Sand the pieces on sandpaper or with a Dremel tool. Be careful not to breathe in the dust as it is harmful to your lungs.

Step 5: Compile

My board came with plenty of holes, but if yours didn't you will need to drill a small hole in the top of your board for the jump ring to go through. Slide a jump ring into the hole. Attach your earring hook to the jump ring.

Step 6: Display

This is a great way to upcycle all those PCB's you have lying around and make a fun gift for someone.

Thankyou so much for looking at this instructable. Please comment below if you thought anything could be done better or if you have any questions. If you made it please show me as I really want to see my design in action and hit the "I made it" button below.

    Don’t printed circuit boards contain hazardous materials like lead, nickel, mercury, and others?

    Great point LyornL , you need to be careful which types of circuit boards you're cutting and also wear a respirator when doing so. You are right they contain lead and nickel in small amounts but near to no mercury.
