Raspberry Pi, creepy Zoltar Like Fortune Teller help

realgeneralgrunt

Hey everyone!

 

I'm a puppet builder/composer/ jack of all trades working on my next project: My own original fortune teller machine.

 

To get it out of the way right off the bat: I'm NOT a programmer. I can figure SOME stuff out but 99% of coding I'm not good at at all.

 

Now onto my project:

So thus far, I have gotten the entire automation done (not shown are the LED lights)

 

I used a Mini Meastro 12 Servo Controller, 1 servo, and 3 LEDs (Monk RGB LEDs with built in resisters)

 

The head is 3d printed from a model I did in Sculptris, and the music I composed myself.

 

Now here are the remaining steps:

 

Using a coin acceptor:

to activate the sequence.

 

To have the audio track play at the exact moment the sequence starts (the audio in the video is from my PC Speaker that I hit play to sync with the sequence)

 

After the sequence plays, a random fortune is printed using a Thermal Printer:

I'm using a Raspberry Pi 3 for this, but I also have an arduino uno.

 

I was inspred by Matt's Mystic Seer build:

 

Episode 365: Twilight Zone Fortune Telling Machine

 

I'm hoping you all can help me finish the internals so I can start the build on the actual machine!

Like I said, I'm NOT a programmer, so all help would be appreciated.

 

Thanks!

  • One quick note that you should be aware of: Unless they've updated them recently, the Adafruit drivers for this model printer DO NOT work with a PiB3, so you'll need a B2.

     

    Coin acceptor should just send a logic "HIGH" to a GPIO pin when activated. Use that as an interrupt on the Arduino to trigger your activation function.

     

    My best advice to get the electronics working is to make sure you're absolutely familiar with the code structures for each of the components that you're going to add. Get one thing (for example, the motor movement and synching it to the music) done first, then add the coin slot, the lights, etc. If you make the build an iterative process, it'll be that much easier to string everything together later!
