You will not find a ready made, single chip solution, perhaps the easiest way would be to use the sound card in your computer! Every digital approach would ask for at least some of the following: -quartz oszillator -frequency divider -PLL -control electronics -display electronics -output stage You would be amazed what high stability you could actually achieve with an analog RC oszillator. If you combine it with a frequency counter with >1s gate time you would get 1Hz resolution on the display... Instead of a NE555 you would probably go for a MAX038 or XR2206 as central part of your design. For some more infos: http://www.epanorama.net/links/oscillator.html Uwe.
