Description
This is a cordless, non-electric phone amplifier.
Made to look like an 80’s Boombox.
You can change the cassette to read anything you like.
I designed it to accomodate nearly every smart phone on the market.
Here is a video demonstration.

This used a lot of material but, it does sound really good. I love the design! Nice job Steve!
