Here's a site for you: (Yes, I'm looking at you, Nuke)

I remember this, we used it to design circuits in high school electronics. It's adequate for simple circuits. If you want, they can even make the PCB for you (although that costs a little bit, it still isn't too bad).

I prefer KiCAD, since it's free, open-source and multiplatform. It also lets you design the circuity itself, not just a PCB. Granted it still has a number of shortcoming (in other words it isn't yet on par with Eagle), but it's getting there.

i know how to cut my own circuit boards. i learned this in my high school electronics class. but lately ive had electronic tinkering on the back burner.

Is there a similar app for Mac? (no, Kicad is not all that multi-plattform)

[Inquisitor]

I haven't etched a circuit board of my own since 1990.

theres always the marker and acid technique, how well can you draw?
laserjet + thermal transfer paper is the high tech way to do the same thing. when i did it the marker technique was used to fix errors in the heat transfer stage.
