    I'm building a variable speed fan controller (tutorial at
    http://casemods.pointofnoreturn.org/vregtut/) and I would like to add
    an IC to display the 10 seg LED to display the level in bargraph
    display. But I can't remember what part # it is! >_< I'm pretty sure
    it starts with LM3xxx so can anyone fill in the missing numbers? TIA!
     

  2. That sounds like the good old LM3914. Try this:
