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
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.
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.
Adhering the Pieces Together
Using standard wood glue, adhere the PCB to the wooden base.
Adding Epoxy
Since the PCB board has little bits of solder sticking up, it would be a good idea to cover the surface with clear Epoxy Resin. This can be purchased on Amazon, using the link below.
