Madam K Skeleton Fortune Teller

The fortune teller is unlike most fortune teller machines in that it will insult you. When trick-or-treaters knock on the door, they are always drawn to the skeleton fortune teller. I change the dispensed fortunes and the fortune show to be age appropriate during Halloween. The fortune teller is controlled by two Arduino microcontrollers and a Pololu Maestro USB servo controller. I also use a PicoVolt controller to operate the arm side to side motion so that it appears that she is waving her hand over the crystal ball. The arm will rise upward with the help of a Firgelli linear actuator. When the fortune reading is complete, a fortune will be dispensed. The cards are just business cards that I print at home. The fortunes provide a "Joke of the Day" along with other fun facts. I listed a few examples in the construction document. The document is 58 pages and provides everything including cabinet construction. You can also download a complete set of electrical drawings in .pdf format to accompany the construction document. Since some of the spoken fortunes have jokes that are less than appropriate, the other videos can be viewed at www.guarnero.com

The code listing for the Arduino's and the Pololu Maestro is located int he Construction document.

The Arduino Uno R3 reads when the coin inserted input is connected to ground. The Arduino Uno R3 also determines the show animation and audio file to play and sends a 4 digit binary code to the Audio Player Arduino Uno R3 that represents the desired audio file to be played. In addition to sending the 4 digit binary code, it also requests a subroutine to be played to the Maestro. Refer to the electrical drawings for hookup information. Currently, I am only issuing three different shows but I have the ability to issue 15 different shows based on the binary code available. The Arduino code is listed below.

The Pololu Maestro controls the RC relays for the Crystal Ball, Star Ceiling, PicoVolt trigger, and Fortune dispenser trigger. The Pololu Maestro also controls the Firgelli actuator.

The fortune teller is powered all of the time. To extend the life of the head servos, a RC relay is also controlled by the Maestro to only provide power to the relays when a show is active. Since a PicoTalk provides power to the servos and the PicoTalk is always powered on, a 12” extension for each servo was added and the power wire routed through the RC switch. The PicoTalk power is left on all of the time since it also controls the LED eyes and I wanted this to always be active.
