Bomani, Eunice, and Matt have created a project called Waves which allows you to see the spoken word in printed form. A set of colour-coded questions is posed and you are then invited to answer them whilst pressing a colour-coded button. The appropriate question and your response are then printed out using a thermal printer – the question as text and your response as a sound wave (pictured above). You can read how they did it, and perhaps create your own, by viewing more about the project over at GitHub and see it in action below.
