Simple PCB Trivet

Introduction: Simple PCB Trivet

This is a simple and fun project to do with recycled PCB (printed circuit boards). I pulled one out of a broken stereo system, but you can find these boards in a variety of electronics. A trivet is an object placed between the serving dish and the dining table, usually to protect the table from heat damage. This project will require some work beforehand to remove small pieces from the back of the board, but it is definitely worth the effort, providing a functional piece as well as decorational!

Supplies

  • Large PCB board (about 1 foot square)
  • Channel locks
  • Pliers
  • Diagonal pliers
  • Metal file
  • Pallet
  • Nail gun
  • Miter saw
  • Wood glue

Step 1: Preparing the Board

Using channel locks or a variety of pliers, remove small electronic parts from the back of the circuit board. I found out that the simplest way, was to use channel locks to twist the pieces free.

Step 2: Making the Base

Cut two pieces of a pallet, that are slightly wider than the PCB. Then cut two more pieces to lay across the bottom, to hold the pieces together. Using a pneumatic nail gun, nail the four pallet pieces together, to form the base of the trivet. If you would like, you could also sand the surface, to give it a more finished look.

Step 3: Adhering the Pieces Together

Using standard wood glue, adhere the PCB to the wooden base.

Step 4: Adding Epoxy
