This circuit bending hack takes advantage of those audio ... After pulling out the oscilloscope for a bit of reverse engineering, [Jason] grabbed a PIC microcontroller and added it to the same ...

In the end, [Martin] says just about any pattern will work for kerf bending, so long as the design isn’t diagonal to the bend. We’d love to see some proper engineering analysis for kerf ...

The film "Fatigue In Engineering Materials" explores the concept ... including rotating bending machines and servo-controlled testing machines. The film also discusses the significance of stress ...
