They often have several windings, which helps build oscillators. More

Try asking Grok, Bill. Or else your preferred AI assistant. Works for
me.

 He could strain his imagination to its limits and google
      ccfl transformer

Did it find anything for you?

And then he could try designing electronics.

I've been doing that for some fifty years now, and have had some objectively verifiable successes, not that you are temperamentally equipped to appreciate other people's successes.
Try and find some other put-down. You might find one that works, eventually - that does seem to be how you find the "designs" (such as they are) that you post here.
