the project is in a 'closed environment' and every student received a topic. i got this one

i ran out of ideas and that is why i have posted here. it's not something ilegal if i tap my own phone is it ?

also.. i couldn't find the email address of irongeek, so if anyone has it please send it to me or send this post to him so he can check it out, maybe he has some ideas about solving my problem

thanks
