Is it possible to make a Voice Amplifier with an old cell phone? Answered
Unfortunately I have accumulated a few cell phones over the years and I never knew what to do with them other than use them as glorified alarm clock or contact list. The last few months I wanted a megaphone/voice amplifier to use on my school bus. I started to think that there must be a way of using an old cell phone with a mic and something over the speaker to amplify the sound. Sounds like a great puzzle/project for someone with the knowledge! Is this possible some way? Thanks!
