please help me with the ultimate sports fan sign

I've made the sign but still need help with the electronics, I would like to power it with old phone chargers and the flashing circuit is still a puzzle

Perhaps a comment directly on the instructible would be a good place to start.

If you're in a stadium it needs batteries - if youre planning to use it in your window at home, then get a dc transformer 'wall wart' charger that outputs the voltage you need. If you are having trouble with the 2-transistor flasher (some people find it intimidating if they've never worked with electronics) then just use a car turn signal flasher. Get the kind that has 2 outputs, or wire it up with an automotive relay to flash between the 2 circuits.
