Blinking light box??

Electronics is also one of my hobbies. I built a circuit exactly for this some time ago, but I used a 12 volt LED strip. I can give you a schematic if you want to build something.

Or build this one:

The schematic is here: http://www.velleman.eu/downloads/0/manual_k8033.pdf Just change RV2 from 47K to to 200K and that should give you 10 seconds on time.
