Dune Weaver Pro Assembly Instructions - tuanchris/dune-weaver GitHub Wiki

Assembly instructions

• Assemble the IKEA leg upside down

• Add the base and secure the base aligner underneath with 4 M4x15mm self-tapping wood screws

• Connect the motor cable, add the motors and secure the motors to the holder with 4 M3x10mm machine screw for each motor. Secure the motor with the aligner to the base with 2 M4x15mm self-tapping wood screws for each motor.

• Add the bearing to the outer bearing holder like so. Secure with M4 set screws or scale the model for a tight press fit. You can also use a dap of glue to hold the bearing in place.
• Add the inner bearing to the angular gear and glue it in place. Wait for the glue to completely dry.
• Press fit the angular gear to the bearing. Add set screws or glue to secure it in place. Make sure that the inner bearing moves when the angular gear moves.
• Add the assembly to the base and secure with 4 M4x15mm self tapping screws.

• Add the radial arm and the inner spur gear

• Secure the Raspberry Pi 2W (with usb cabled attached). Then secure the dlc32 board on top of the usb cable. You'd want to stop here and move on to Electronics to make sure everything is working, before moving on with the wiring.

• After you're done with the wiring, you can put the electronics cover on

• Trace and cut out the EVA to the shape of the wooden base. You may add a dab of glue to the edge if your EVA foam curls up, but don't add too much glue.

• Add the led wires

• Assemble the enclosure around the wooden sand bed like so

• You may want to caulk the bottom of the sand bed to prevent sand from getting out

• Add about 1.4kg of sand and the magnetic ball. You'd want the sand to cover about 25% of the height of the magnetic ball. Install the LEDs and solder in the connection

• Add the LED cover to the glass and put the glass ring on

• Put the sand bed on the four legs. Add the glass ring with the glass on top

Wiring

• With this design, I use a single 12V 5A to power everything. Whether or not you can use the same power supply depends on the LED that you choose. My LED is 12V WS2815 60 LEDs/m. If you have more LEDs/m, you may need to increase the power supply's current.
• I use Duponts wires to power the Pi Zero 2W, and ESP32 board. These wires are known to cause a lot of problems, so after confirming everything works, you can consider soldering the connections in.
• Confirm that all electronics work first, before you put everything in place.
• Connect the power cable to the female 12V plug and run the power wires through the steel tube
• Refer to the wiring diagram, create a plug here so that we can take off the LED when taking off the table top
• The green cable is the data cable, will be connected to pin 16 on the ESP32
