Handcrafted Circuit Boards

The most challenging aspect of handcrafted circuit boards lies in the wiring of the circuits. Most existing technologies can only utilize planar wiring principles, making it difficult to adopt three-dimensional wiring, indicating that this is also a direction for development. Below is a sound-controlled clap switch circuit, which can be constructed with just thirty components. … Read more
