Hologram

Euphoria

Project Overview

Euphoria is a 3d holographic display for your setup and you can display whatever you want on it from anywhere in the world using the WiFi.

Why I Built This

I was looking to build something, i searched for many ideas and I had liked a women safety device at first but that didn't make some sense so i started looking again and then i found something on my youtube recommendation it was titled "real holographic displays" and it showed a similar holographic display using the pepper's ghost technique and I really liked the idea and I wanted it on my desk too so i started building it immediately.

What's Inside This Folder

PCB & Hardware Files:

• hardware/gerbers/ - All Gerber files for PCB manufacturing (e.g., hologram-F_Cu.gbr, hologram-B_Cu.gbr, etc.)

• hardware/pcbs/hologram.kicad_pcb - The main PCB layout file.

  

• hardware/pcbs/hologram.kicad_sch - The main schematic.

• hardware/pcbs/hologram.kicad_pro - KiCad project file for editing.

• hardware/fab/outputs/3d/updated-pcb.stl - 3D model of the PCB.

  

Firmware:

• firmware/eidolon/ - All firmware source code.
  • include/ - Header files. 3D Case Files:
• hardware/fab/outputs/3d/updated-pcb.f3d - 3D models for the PCB.

Build Guide

Step 1 - Export Gerbers from KiCad

Open hologram.kicad_pcb in KiCad, then generate gerbers and drill files. Zip all outputs together.

---

Step 2 - Order the PCB

Upload your gerber zip to jlcpcb and place your order.

---

Step 3 - Solder the leftover parts

• Battery connector
• Speaker connector
• Microphone connector
• Oled connector

---

Step 4 - Connect the Battery

Use a flat LiPo battery with a 2-pin JST PH2.0 connector.

---

Step 5 - Connect the Display

Connect the 1.3 inch 4 pin Oled display module.

Step 6 - Flash the Firmware

• Use PlatformIO to flash the firmware in the ESP32-C3-WROOM-02

---

Step 7 - 3D Print

• Material: PLA works.

---

Step 9 - Assemble the Pyramid

Cut your transparent acrylic sheet into 4 identical trapezoid pieces and place them accordingly.

Modifying the Firmware

• All main configs are in include/Config.h.
• Each feature is in its own file.
