Okay, I'm pretty new to phreaking and electronics in general. I've built a basic beige box and i'm looking for a bigger challenge. Besides the red box, what are the other boxes that are made for novices?

I found my telephone box on my house and i plugged my beige box in and it worked fine. Are there boxes like these on EVERYONE'S house?
