Hi there,

this my first try to add somthing to the site, it might not be that good, but next time it will be better :)

My wife asked me once to make something for her using LEDs will i guess i made the right thing for her :)
the project is quite simple to make. all you need is a set of  LEDs, 555 timer, some resistor and capacitor and project box to put everything in.
