Need reliable electrical or mechanical 24hr timer

  1. Apr 18, 2013 #1
    It needs to perform at least 50 cycles with a cumulative error of no more than [+\-] 30 minutes. This is for a home project.

    Any suggestions of components?

    I'm not sure I understand...why can't you use a clock (either electrical or mechanical)?
