Just in time for Christmas. A 10 pointed star with green LEDs and red LEDs on alternating points. Run by a PIC16F1517 44-pin microcontroller.
All surface mount 0805 LEDs and resistors and the TQFP PIC.
700 lines of C code.
Two-sided boards made by Osh Park (the descendant of BatchPCB), 3 boards for just $19.
I am wearing this for Christmas dinner tomorrow. It looks much better in person, very bright, very nice red and green color. And the dimming effect, unlike on the video is smooth. Makes a great tree ornament as well.
