Front side connections
The front side of the raspberry pi pico.
Switches
Solder two switches to the raspberry pi pico as shown
| Function | Connect to |
| Bottom switch | GND and GPIO11 |
| Top switch | GND and GPIO20 |
Servos
Cut two female servo harnesses to 6″ lengths. Label one SERVO 1 the other SERVO 2.
Solder SERVO 1 to the animator using the following table.
| Connect to | Cable Color |
| GND, pin 3 | BRN |
| GPIO2, pin 4 | YEL |
| 5V, pin 39 | RED |
Solder SERVO 2 to the animator using the following table.
| Connect to | Cable Color |
| GND, pin 8 | BRN |
| GPIO6, pin 9 | YEL |
| 5V, pin 39 | RED |
Actuator assembly
Plug the figure servo into SERVO 2 harness. Power on the AN2S and let it initialize. Press the figure mount oriented as shown.
Plug the rotation arm servo into the SERVO 1 harness. Attach the rotation mount to the servo with glue and the screw provided.
Mount the rotation arm servo to the mounting plate using the screws provides. Repeat with the figure servo.
Mount the retaining ring using three M2.3X8 screws as shown.
Controller assembly
Insert the buttons in the controller cover as shown. Tape them in place on the outside.
Place the board into the controller base. Route the wires to be out of the way of the buttons.
Snap cover on.
Test controller assembly
Plug in servo1 and servo2 into the controller.
Hold the pico program button down and plug in the microUSB computer cable. The unit will load into boot loader mode. Copy the circuit python UTF file over to the pico.
Once the pico boots as a circuit python drive delete all the files on the drive and copy the big foot code onto the unit. The unit will boot and initialize to the home position.
Press the “top” button confirm that the “big foot” animation occurs.
Press the “bottom” button confirm that it goes into “program mode”
The controller is now tested. Set aside.
Cut 0.032in wire and bend as follows.
Big foot figure
Insert this rod into the figure as shown with the loop end facing rearward. The 90 degree bend help pot the figure in place with glue. Let dry overnight.
Note: the figure turntable is designed so that the main rod is in the center. The insert end should clear the servo mount. This puts the main rod in the center of the slot.
Paint
Paint figures with brown and black mixed together in equal parts.
Calibrate the control assembly
Get a rotation assembly and controller. Mark them both with a number using removable tape. These items will be packed together.
Plug in servo1 and servo2 into the controller.
Press and hold the “top” button in for “hidden” or the “bottom” button in for “visible” continue holding these buttons and plug in the power supply. Continue holding until you see big foot start to move. Release the button. It should cycle four times at the middle position which indicates that it is in limit adjusting mode. Then it will move to the “home” position.
Insert the figure facing forward.
Press the “top” button to move the figure to the rearward and the “bottom” button to move the figure to the forward.
Once you are satisfied with your adjustment press and hold the “bottom” button until the figure moves forward and backward.
Repeat the above steps for each position.
Unplug the unit and plug in the power supply that will ship with it. Confirm that the platform rotates and does a single cycle.
Unplug everything and the controller rotation assembly and power supply is ready to pack.
Packaging
Put 6 M2.3 X 8 screws in bag. Heat seal.
