LM317T Voltage Regulator with Pass Transistor

88flak RC infra red gun diorama, 1/18 scale. Using Mitosal mini-ACT-A01 with Tamiya protocol, ELV mini-USB soundcard, 2ch radio, 7.2V battery pack and a voltage regulator circuit (5V for the sound card and receiver). Visaton FRS5 speaker. Impact receiver apple and IR led. The sound samples are triggered using a microservo operating 2 microswitches. The sound card triggers the miniACT to fire. Set at 2 Lives, fires every 3 seconds. The gun rotation is operated through a microservo put inside the gun base. The IR led is in the recoil absorber under the barrel, while a flash led is in the muzzle. Sorry for the poor video direction and shooting, I had to control too many things by myself.
