I can't remember the first Dalek series. What I do remember is building a Dalek machine, using a ring modulator from a design in the first-ever issue of Practical Electronics (article name: Electronic Didgeridoo), and annoying the other kids at school with it. I *think* I've still got the ring modulator itself somewhere, in a drawer in the garage.

.... The only thing it couldn't do was render "I think I ought to tell you I'm feeling very depressed" in a sufficiently-realistic Marvin voice.
