In order to evolve your Circuit Tank 1.0 you need Doc Zap’s Even More Secret Identity Badge. Just like the first Secret Identity Badge, you need to answer a series of questions which will lead you to the badge.

Once the quiz is completed, you will enter your login info and the badge will be added to your Nanovor acount.(This no longer works.)
