I took the schematic and theory of a MiniPOV2 and adapted it to make a hat for Halloween. It is basically the same circuit as a MiniPOV2 but with a few different components to make it fit the hat better. As usual, I never take the time to document things as I’m building them. I’m just too excited to get the project built. So what you’ll see is a retrospect of what I did, and some changes in what I would do again.

Mini-POV kit! The 3rd generation MiniPOV is perfect for beginners who are looking to learn how to solder, how to program microcontrollers, or make LED blinky toys. Because the programmer is built into the kit, you don’t need a special “microcontroller programmer”. This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).
