Introduction: Xmas Holograms

Let's create a simple Xmas hologram. What would you need is a 3D printer, Acrylic Sheet, and CNC router or optionally a modelers knife if you don't have one and a soldering gun or station.

Electronic parts that would be needed are following:

  • bright white LED e.g. 504WC2E-W6-3PC
  • 00 ohm resistor
  • 18650 chargeable battery (3.8V)
  • CL 5V Micro USB 1A 18650 Lithium Battery Charging Board
  • couple of wires
  • 18650 battery case
  • and optionally a Mini Rocker Switch SPST ON-OFF S654

Other material

  • acrylic (plexi) sheet of 2 mm thickness

Step 1: 3D Print

Firstly you would need to print the base for battery and the LED light. Use the STL or GCODE files above. You can find and option with or without a switch. Chose based on your preference.

Advantage of a solution with a switch is that the light can be switched off without need to remove the battery.

Step 2: Wiring

Secondly you would need to solder the component together and place them in the case.

Connect battery case to B+ and B- contacts to the charging board (+ to +, and - to -), optionally interrupted by a switch (solder in the case, if you do outside you would not be able to push wires thru)

Then continue with resistor and LED to OUT+ and OUT-. If you are not sure how to connect LED properly, check the LED and you will see a flat place by a contact that's supposed to be connected to negative battery end. (easy to remember - indicates the flat side ;))

Place all connected parts into prepped position in the case and feel free to charge by any charger with USB B mini connector.

Step 3: Acrylic Hologram

Now lets prepare the acrylic sheet holograms.

if you have CNC router use the gcode file to create the holograms, use a thin spike routing bit.

The other option is to create the picture manually by a modeler's knife or manual manual engraver to draw any motive you would like.

The final size of the acrylic sheet needs to be 85mm x 85mm to fit into the groove in our base.

Step 4: Finalization

Finalize by placing the acrylic sheet into the 3D printed base and enjoy.

Examples of a final product can look as pictures above.

PS: when charging you would see a small red light, when fully charged you would see a blue light in a bottom corner.

Happy creating, tinkering, basteling ;)
