Copper Cobweb Circuit Construction

Are you bored with conventional two-dimensional circuit layouts, or looking for a way to add an artistic flair to your next project? I’ve taken point-to-point construction style a step further by making it self-supporting, which opens up a wide range of physical circuit topologies. (Point-to-point construction usually uses supporting structures like terminal strips that are functional but not pleasing to the eye.) I call this construction style the copper cobweb. Here’s how to do it.

LEDs for Operational Status and Troubleshooting

Even when a circuit functions as it’s supposed to, it’s not always easy to tell what it’s doing. Plus, waiting for an output (especially if there’s a long delay involved) is not always practical. Conversely, if a circuit does not function, the only means to find out what’s wrong is to troubleshoot it with either a multimeter or oscilloscope. Wouldn’t it be great if the circuit itself could tell us more directly what’s wrong?

Build Your Own Funky STEAMPUNK Display

I use LCD displays in almost every project. However, in this modern age of steampunk, I stumbled on something much cooler — 1” high seven-segment electromechanical displays (EMDs) that go clickity, click. Here is an ambitious project that features five 1941 vintage rotary phone step-by-step (SXS) switches. These EMDs are the perfect match to display the dialed digits.
