im trying to build a simple relay bourd that basicly has 8 led's and a push button
and every push turnes on the next led in sequence and only 1 led on at any time,
so you push the button and the led light moves to the next and when gets to the end restarts the sequence,
and i only want to use relays and basic newby components

any help will be very very apreciated

thanx
 
CD4017 with a transistor driving each relay and a reset at 8.

See the datasheet.
 
Here is a relay counter that can be extended to as many LEDs as you wish.

For 8 LEDs you can either just provide 8 relays or if you want to reduce the number of relays, it can be done with 5 by making N1 ~ 4 cycle twice.
