After having seen so many propeller clock POV videos on Youtube, but no real description of how they work or how to build your own, I set out to make one and document how it was built. The Pyro Propeller Clock POV design criteria was short and sweet: be as simple as possible in order to encourage others to make their own, DIY style.
The clock’s main components are a PIC 18F252, 74LS373 latches, and a 3800 RPM fan. (Note that “propeller” in the title comes from the rotational property of the design; the project does not use a Parallax Propeller MCU.) Checkout PyroElectro for the complete project description, including build instructions, schematic and code.
