Here are some neat circuits you might want to try. The schematics and printed circuit board patterns are GIF's, and may show up different on some browsers. You might want to save the images (especially the PC board patterns) to your hard drive, load them into a photo editor (Photoshop, Paint Shop Pro, The GIMP, etc.) and adjust the size before you transfer the pattern to a board. Printed circuit board patterns are available possible. This page is always under construction and there will be new additions from time to time. Some of these circuits were designed by me, most are not. Whenever possible I have tried to credit the author of a circuit but since many of these circuits are from my personal collection that I have gathered over a period of many years, this information is not always available.

You can rank circuits according to how much you like a circuit by clicking on the lightning bolt icons. These ranks can be based on how much you like a circuit, whether a circuit worked or didn't work for you, or how useful you found a circuit. Additionally you can add your own comments at the bottom of each circuit by filling out the form.
