Alternating led circuit with 30 second delay.

[hundshamer]

Hey guys I want to make a small circuit that will power 2 led strips alternating every 30 seconds.

That's great. Go right ahead then!

Let me start over. I need some help designing that circuit so I can use it in a case mod. If someone can point me in the right direction or has a schematic I can use, it would be greatly appreciated. I can find videos on how to get them to alternate, however none of them explain how to time the lights. Can anybody help?

Sorry if this is in the wrong topic. Moderators please move topic if nessesary.

Maybe adapt this in some way?

I was thinking about something more like this:

that doesn't that give you a single 30 sec switch circuit?
16 leds? why?
8 lit at a time....
transistors are needed for every one or look for a multi timming on/off state IC chip....
