Your ultimate AI recipe generator slot machine
Fortuna was built as a part of a two week long course called Tangible User Interface taught by the amazing Massimo Banzi and Pierluigi Dalla Rosa at CIID in 2025.

PROTOTYPING JOURNEY
We started experimenting with a brushless DC motor
We put together a simple frame to hang the slot machine rod on and test the rotation - it was so strong we had to lower the intensity to stop everything from flying away.
We added a handle attached with a rubber band to give it a pull effect to trigger the rotation.
We tested out a tiny adafruit receipt printer separately and connected it to an arduino with serial commincation and a script which used chatgpt's API to produce a unique recipe with any ingredients being the input.
We combined it all together - we had two arduino's speaking to each other using serial, a printer, a motor, and to heat the printer for the ink to work properly, we used a 12V source.
Combining two serial connections was tricky, it needed a lot of debugging.
We made a final casing using a shiny acrylic to give it an arcade vibe.
There was a lot going on behind the scenes!
We added LEDs for visually showing the different states of the slot machine and a print button to initiate the print!
