This is kinda off topic but, can someone please help me with this...I am trying to get a 555 timer rectangle pulse (Basic Astable) to stay low longer then it is high...Is this possible? I have achieved near equal (square) but never longer low then it is high?? Thanks for any help.

You need a couple of diodes to do that - look at the 555 application note from National. If you can't find them I'll send a suitable schematic to you direct.
