Killer Talking Halloween Pumpkin Prop w/ Animatronic Eyes

I wanted to make a talking head with animatronic eyes for Halloween so searched and found a great pumpkin model I liked so I remixed to make it work with a great set of animatronic eyes. 

After asking permission from the designer I remixed this pumpkin head. I cut it , gut it. Added a shelf for the eyes to slide into, holes for magnets to keep it together. Then I slapped a bunch of electronics inside till it came alive. I replaced the hat to save space and time as its a little big, but still I have files for it that as well. I haven't tested the hat but should be fine. Also including the no hole version of the back plate for those that wanna edit for their own cord.

You can always print then toss in a tea candle or pre-wired lights etc and have a lighted pumpkin.

Below is a list of models used and parts list. 

I will put a full description with code on my site as soon as I get time.

NEW : Code Added to download.

So the top is the eye mechanism and the PCA9685 board glued on top. Underneath the eyes is the esp32 with expansion board, a smaller breadboard with a dfplayer mini and sound sensor on it, then a small speaker hot glued to the included base plate. A 24-12v to 5 v converter to run it all glued into the back. I aligned the expansion board and drilled holes and screwed the expansion board directly to the printed plate. The breadboard had adhesive so just stuck it on. All fit really well with the parts I used. Wiring is tricky but it all fits. I also have a mouth plate that you can print and bend down the middle to curve it to fit the mouth. It kinds just clicked in and stayed for me pretty easy. I also took a piece of black felt and cut out eye holes to cover the extra open space  that might let them see inside around the eyes.

My version of code has a webpage with 3 buttons to open the eyes and start looking back and forth then play one of 3 different preloaded sounds that are loaded on the sd card of the dfplayer. After that it waits till 20 sec has past and closes. Can easily add more sounds and buttons and do different things with eyes etc as you want. The lights work with an audio sensor to make the mouth look like its talking and should respond to any audio you wanna use.

PRINT: I printed everything in current orientation with tree supports at .2 on a .4 nozzle with my Kobra 3v2 so should fit most printers. I used 15% lightning infill for faster printing and to keep it light and worked out great.

Pumpkin model (Asked the designer and said it was ok to share)

Animatronic Eyes Model Great model with parts all printable but the motors. One of the best ones out there I've seen.

PCA9685 case I put the controller in the case and glued the case to the top back of the eye mech. (White part in pic with wires sticking out) Used painters tape and twist ties as needed lol.
