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
- 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 ;)
