4017 LED chaser

after a long long long time.. i finally built an LED chaser, as instructed here:
http://www.doctronics.co.uk/4017.htm

in the beginning i used the 4093 astable , but it didn't work properly..
so after some trial and error, i succeeded!
i gave up the 4093 astable, and only used the 4017, with it's "reset", "clock" and "enable" wires free of contacts!
