Yeah I was talking about the Brick Night-Day system too. It is possible to make this work. I Once made a machine that went on forever and if I wanted to, I could surely make night and day. The main part consisted of only two bricks that shot a bullet at each other, every few seconds through wrench events. Then, it was easy, just wrench event: On Projectile Hit<and then,whatever the heck you want!
Be sure to put these two bricks far away so they don't make too much noise in your build. Oh, and if you want things not to happen as soon as the bullet hits the brick, just delay something! Good Luck and tell me if this worked for you. Put these saves in your slate and observe, but you need to have LOTS of Add-Ons because my machine involves many! Sorry if the save is messed up, I haven't been on it in a while so it might malfunction.
