still very WIP; instructions may be inaccurate.

Bill of materials

• Orange Pi 5
  • microSD card
  • AP6275P PCIe Wi-Fi module
• AnyBeam mini laser projector
• ELP 3DGS1200P01 V83 stereo USB camera
• Waveshare UPS 3S module
  • 3x 18650 lithium batteries
• KW12-3 micro limit switch (trigger button)
  • 1k ohm resistor
  • trrs cable for grip trigger button
  • trrs socket to plug in trigger button
  • trrs cable for speaker
  • jumper cables

Tools

• M2.5 driver

Construction

1. Install Wi-Fi card in Orange Pi 5

2. Solder jumper cables to the 3.5mm socket

3. Use a soldering iron to sink the threaded inserts (1x 1/4in for bottom tripod, 4x M2.5 2.5mm for front panel, 4x M2.5 2.5mm for back panel) into the chassis / front panel

4. Glue neoprene rubber to the inside of the chassis to keep the projector stable

5. Attach standoffs to the Pi and battery

6. Plug GPIO pins

7. Remove the charger and power button cables from the battery and take off the rings. Attach the charger and power buttons to the back panel

8. Put the battery and Pi into the chassis. Bolt the battery and Pi standoffs in
