The system only works with an Arduino Teensy 3.2 and 5V battery pack plugged into the Teensy. The chosen Voltage Regulator does not output enough amps to power the Teensy and all the LEDs. While we didn't notice any brown-outs the LEDs were dim and we barely tested it with the VReg after that. A new, higher power VReg should fix the issue, though the socket for it might need to change.

Leds and IR-led don't need a voltage regulated power, just a current limitation (like a resistor). I know you're using the integrated Teensy output pin current limitation to drive your leds but you can increase (or decrease) the leds number without burning Leds, Vreg or Teensy if you choose to drive transistors.

LEDs will draw as much current as they need if you give them the proper voltage with enough current, so current limitation is not needed.
All LEDs are toggled by transistor (IRF5X0 or shift register), the only pin on the Teensy that is used is the 3.3v regulated output for power.
