Introduction: Anna, the Fortune Teller
This is an inspiration from Zoltar, There are so many versions out there and I wanted to make my own cubicle version. We have a fortune teller in a booth who gazes her crystal ball and tells your future :)
The build is a mashup of paper craft, light box, Arduino and loads of glue !
PS - This was built with materials already available at home, you will be able to skip some steps if you have access to color printer , arduino shields
Supplies
Fortune Wheel/ Carousal
- Card stock ( 120 GSM or higher / Blank business cards)
- Tooth pick
- Pencil / Stick
Fortune Booth
- Colors (Crayons or anything you like)
- PingPong ball
- Masking tape
- Scissors
- Cardboard
- Glue
Electronics
- Arduino
- DC Motor box with wheel
- RGB LED
- White LED Strips
- ULN2803 or any motor driver
- L293D or any motor driver
- PING sensor (Ultrasonic distance measurement)
- ISD 1820 with AMP or any other trigger enabled audio playback device
Step 1: Making the Fortune Teller's Booth
Steps below, please refer to photos for more details
- Cut 1 Inch cardboard strips
- Clean up a shoe box
- Blue the cardboard strips from step 1 as a frame within the shoe box
- Add a background of choice to the frame
- Add elements like curtains to the frame
- Draw or print the fortune teller from https://www.vecteezy.com/vector-art/186962-fortune...
- Cut along the outline and stick it on to the frame
- Draw/ print the hands from the earlier picture and add again to the frame. At this point it should look like a 3D image
- Add RGB LED and ping-pong ball to the frame
Feel free to add as many layers as your wish, more layers means more depth to the picture.
Step 2: Making the Fortune Wheel
Steps below, please refer to photos for more details. This is a poor man's version of https://github.com/scottbez1/splitflap . I just wanted to make a version with parts already available at home
- Cut two circles of diameter 3 Inch from a thick cardboard
- Mark points 15 Degree apart from each other and draw another circle of Diameter 2.5 Inch
- Punch holes at the mark, Stick a pencil as a spindle for the wheel
- On the other wheel, punch out holes and tie a wheel so that it can be connected to motor
- Glue the other circle as well to pencil
- Cut flaps out of index card
- Insert tooth pick and glue the cards to the tooth pick
- Add the motor to the contraption
Please note that this fell apart after about ~ 150 times, If you want this to last long, please add supporting structures on both sides. Also glue and moving parts don't go well together :)
Step 3: Setting Up Lights and Sound
The setup consists of one motor, ping sensor, RGB LED, two LED strips and one audio device ( ISD 1820 Module). The RGB LEDS act as a crystal ball, The LED strips light up the background of the booth, audio plays an introduction to the fortune teller and the motor drives the fortune cards.
ISD 1820 plays a single audio recorded based on a trigger pin. This is connected to an amplifier and played over speaker. I used UK-Rachel voice from https://www.naturalreaders.com/online/
- Connect the components as shown in the diagram. Note that the upper railings on the bread board has VIN and the lower railing has 5V connected to it
- Upload the code to your Arduino
- Place all components within the box
- Place the ping sensor on the outside of the box
- Power up and its ready !
