Unihiker chattering teeth optimistic news reader with ChatGPT
This UNIHIKER - a tiny Debian Linux board with integrated touch screen - was programmed to get the latest news headlines via RSS feeds.Ā
Ā
Before speaking, OpenAI ChatGPT API rewrites the headlines, but with a twist. ChatGPT is told to rewrite them with a happy, optimistic tone. The response is then fed into Google Translate's text-to-speech API that generates an audio file. The audio file is then played with the help of a Bluetooth speaker. As the audio file is played back, an SG90 servo motor moves a set of plastic chattering teeth to open and close it as if it were reading the headlines for comedic effect.
