Etching wood with arcing electricity!

What happens when you take the high-voltage microwave output from a microwave transformer and connect it across a dampened sheet of wood? Conduction, arcing, fire, and smoke!

All that fun, and you get awesome patterns left behind from where the wood has been vaporized. Once the fun is over, a bit of cleaning up and a coat of varnish yields a piece of art:



This is another project from Mike Churchill. He’s also experimenting with gluing (and perhaps melting?) small plastic beads into the deeper parts of the “image” to highlight their shape:


Perhaps we’ll be able to make this into a demo for the space at events like the Maker Faire?
