I have seen commercially available pendulum clocks as you describe, although the pendulum pivoted on the bottom, and was springloaded hard plastic. The PIC project you describe is something I have been thinking about for about 2 years, but have been *WAY* too lazy for that so far... Someday I'll get around to it! I was looking for all the stuff I had downloaded (code, articles, and pictures) from the Internet, but I can't seem to find anything right now. If you do some basic searches, you WILL find it. I'll try to find it tomorrow at work, and if I do, I'll post here, but otherwise, I have DEFINITELY seen some stuff out there that was PIC based, and did what you describe using either a DC toy motor with a position sensor to tell it when it should start displaying, or using a floppy drive motor which could be accurately controlled... -Steve -----Original Message----- From: Bob Wake & Renie McMeeken To: PICLIST@MITVMA.MIT.EDU Date: Monday, August 30, 1999 10:46 PM Subject: Pendulum Clock? > Does anyone remember seeing a PIC driven LED pendulum clock? >I think it was on a site from Italy. > It was quite an ingenious design, using a single LED 7-segment display >strobed on and off at precise intervals to create the effect of 4 >displays as the arm moves back and forth. > I'd like to try it, but maybe on a spinning disk instead.
