This is not an Instructable for a particular device or circuit. I'm using the circuit I made for an Artbot project as an example. If you need a quick and dirty way to fashion a pc board, you can cut out the copper clad with a Dremel tool. Just plan you circuit and cut away copper to form your paths. No etchent, photo plotting or even drilling needed in some cases. Of course, you can't do any real fancy and do complex circuits, but for something simple, this does the trick.
Step 1: Layout your circuit
Use a sharpie to draw where you want to cut the copper clad.
Step 2: Cut out copper
My favorite tool bit to use with the Dremel is a "mini saw" bit. Use it to cut away slots to isolate paths. It's like the reverse of laying out a trace.
Step 3: Check slots and clean
Be sure the cuts are clean. If you need to drill holes do it now before cleaning. Rub surface with a steel wool pad or scratcher pad to remove burrs.
Step 4: Add your parts
You can now add your parts and finish your circuit.
Step 5: Done
Your circuit board can now be used in your project. I'm building an Artbot to show at the Maker Faire and up coming Robogames and needed a simple board to hold a few parts.
