Oh my lord. Why is it that every pimple faced 20 year old with access to a hackerspace invariably builds a crude autodialler once he has finished building his battle robots? Give me strength.
lol... autodialer is actually a pretty good project for learning stepper motor control, but yeah, somehow everyone who builds one thinks it's groundbreaking. I want to build one myself, but I'd only use it to dial random combinations on my practice locks...
