Electronic LEGO DL-44 Blaster Pistol

LEGO Ideas entry: ideas.lego.com/projects/76141
This is a project I’ve been gradually modifying since spring 2014: a full-size replica of Han Solo’s iconic weapon, rigged up with a small microcontroller programmed by Arduino to play sound effects and to make the muzzle flash blink! Making this project was rather difficult to the say the least, and I frequently ran into errors with the LEGO mechanics, the Arduino programming, the sound box, and the battery power — but nonetheless, I’ve succeeded in making custom toy function. Pulling the trigger makes the gun’s hammer and firing pin (with rubber bands) strike a momentary pushbutton, which is wired to the circuit board to pulse the microcontroller’s sequence of blinking an LED and playing a PCM sound clip of Han Solo’s gun firing. The individual sound effect was extracted by me directly from the scene in Episode IV when Han correctly shoots Greedo first!
Microcontroller: ATmega328P-PU, coded with an Arduino Uno
Power: 2 AAA batteries (3 volts DC)
