This is a recreation of the Titanfall Data Knife. It is not exactly the knife from either Titanfall 1 or Titanfall 2, but somewhere in the middle. It features hollow areas specifically sized to accept electronic components. The final assembled knife can be switched on to play a hacking animation with lights and sound.
For a simpler version, see the basic version. No electronics, just a static prop.
This model was designed around the following parts:
12BH510-GR Battery Holder for N-Style Batteries
SPPH410100 Latching Pushbutton Switch
Adafruit Arduino Trinket Microcontroller (5v)
Adafruit Neopixel Jewel (RGBW - Cool White)
