In this video, we explore the tricky challenges in trying to design an electrical continuity tester that can survive almost any abuse we can dish out.

A deep dive into the design and construction of an ambitious robotic art project.

In this video, I explore what it’s like trying to develop an innovative new piece of technology. It’s not always glorious, but it’s often delightful. Always remember to enjoy the process and the journey of life.

As a teaching exercise for my “Technology for Artists” class, we designed and built an all-transistor digital clock using no chips of any kind – as if we were back in 1960. (we cheated a little on the display)

Take and tour of an interesting homemade piece of electrical test gear. We’ll take it apart and explore the inner workings, and cover the theory of operation in detail.

This is a tutorial showing how to make an AC current sensing transformer out of a handful of steel washers. We also do a deep-dive into the design of signal processing circuitry to make our washer transformer into a useful building block.

Take a deep-dive into smart strategies and methods for building circuit prototypes faster and easier, including a method for making instant surface-mount boards.
