You can use these files with the DN2474 inductor, its single-sided so its easy to etch at home. You can generate Gerbers or extract a postscript image (for toner transfer) easily, using EagleCAD, freely available for Mac/Win/Linux.

• Prototype schematic and board files

Here are the final files, for the kit. They use a radial inductor and have pads for a low battery indicator SMT LED. It's doublesided but there's only one trace to jumper if you're not using the low battery indicator

• V1.0 schematic and board files

I then did a minor upgrade to add a pullup and pulldown for better performance
