Raspberry Pi Roundup - print out sound waves, play retro sound effects and touch-sensitive artwork

Ride the Wave!

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.

Retro Sound Effects

James McCullen has taken inspiration from a 1930s Looney Tunes short film called Hold Anything and created a custom ‘typewriter’ that plays cartoon sound effects. He recorded the effects himself and then copied them to a Raspberry Pi which was then inserted into the casing. By pressing the various buttons and turning dials, he can change what sound effect comes out. See the Fleischer 100 in action below and read more at Raspberry Pi.

Dreamy Dreams

Swedish artist, Rebecka Tollens has collaborated with Playtronica to bring her “Connected Drawings” to life. As part of the Daydream / Darkness / Disgrace exhibition in Paris, Rebecka created drawings to represent her dreams. She then made them interactive by using Bare Conductive’s Touch Board and Pi Cap in ‘proximity mode’. When different areas of the drawings were touched by visitors, Rebecka’s voice would be played through headphones, describing the dreams (or, in many cases, nightmares).
