3D DISPLAY HAT RESOURCES
Build Real 3D Visuals With Your Raspberry Pi
The 3D Display Hat uses a high-speed rotating LED system to create floating visuals in mid-air using persistence of vision.
Learn how to setup the hardware, control the motor, synchronize LEDs, and start building your own effects.

WARNING: It is necessary to mount the 3d display to the base or to a heavy surface. Otherwise the display can become unstable and injure.
Step 1
Start by screwing your Raspberry Pi to the bottom of the hex spacers on the 3D Display HAT.
Step 2
Plug in the USB-C to the 3D Display HAT to power the Pi and the HAT. Only use the supplied USB-C or make sure yours is 30W or more.
WARNING

DO NOT TOUCH THE DISPLAY WHILE IT IS SPINNING. Doing so can result in injury.
Pi Setup
Moving the Motor
Once you've started up your Pi there are a few things to note before creating your own holograms. The pin to control the motor is GPIO 4. Setting GPIO 4 to low will spin the motor while setting it to high will stop the motor. Create a simple python file by typing:
sudo nano example.py
In this file set GPIO 4 to low for 5 seconds and then high, this will spin the motor and then turn it off. Type the following:
from gpiozero import OutputDevice
from time import sleep
pin = OutputDevice(4)
pin.off()
sleep(5)
pin.on()
To save hit CTRL+X and type Y to save the changes. Then in the terminal type:
python3 example.py
Turning on the LEDs
This display HAT has 70 Sk9822 LEDs. They are controlled by the clock pin (GPIO 24) and data pin (GPIO 23). To control the LEDs create an example file LED.py
sudo nano LED.py
In this file set GPIO 4 to low for 5 seconds and then high, this will spin the motor and then turn it off. Type the following:
from gpiozero import OutputDevice
from time import sleep
pin = OutputDevice(4)
pin.off()
sleep(5)
pin.on()
Creating a 3D Dot
Once you've started up your Pi there are a few things to note before creating your own holograms. The pin to control the motor is GPIO 4. Setting GPIO 4 to low will spin the motor while setting it to high will stop the motor. Create a simple python file by typing:
sudo nano example.py
In this file set GPIO 4 to low for 5 seconds and then high, this will spin the motor and then turn it off. Type the following:
from gpiozero import OutputDevice
from time import sleep
pin = OutputDevice(4)
pin.off()
sleep(5)
pin.on()
Creating a Square
Once you've started up your Pi there are a few things to note before creating your own holograms. The pin to control the motor is GPIO 4. Setting GPIO 4 to low will spin the motor while setting it to high will stop the motor. Create a simple python file by typing:

from gpiozero import OutputDevice
from time import sleep
