Text to speech? There’s a shield for that

Galen Raben of letsmakerobots decided to have some fun with a SpeakJet speech synthesizer and TTS256 text-to-speech processor, and designed this SpeakJet shield so that he could make his Arduino talk. The project schematic and code are available on the project page. Looks like a kit in the making!

The advantage of a hardware-based solution like this one is that it requires little CPU time to run, however it is also possible to directly synthesize speech on the Arduino. One promising candidate for this is the Cantarino project.

Flex, an interactive wall

digital wall_diagram-v0.1.png

Matthew from Tampa, FL, wrote in to share this interactive wall project.

Three architecture grad students at the University of South Florida created an interactive wall they call flex. The wall reacts with light and motion as people walk by it creating a unique experience. The wall is powered by 3 Arduinos, 5 Maxbotix LV-EZ3 proximity sensors, 12 servos and 2 TLC5940s that control 32 high power led drivers that power 64 3 watt LEDs for RGBW color mixing.
