Step 3Draw out the circuit in mirror-image (optional)
It's nice to have a mirror-image version of the circuit layout to help you with the on-copper version you're about to make.
If your digital camera's around, photograph your drawing and view it mirror-image on your computer. If you're doing the mirroring by hand, remember to flip all the pins on ICs left-to-right. Double-check the orientation of your diodes and transistors.
For this circuit, I didn't do either. I got away with it because the LM317's only got 3 pins and so I could just stick it in upside-down on the topside, and it would be the same as the mirror-image. If you've got anything in a DIP package, this trick won't work -- upside-down is only equivalent to mirror-image if there's only one row of pins.
