Knight Rider

scrpn17w

This is my build thread of turning my 1999 Honda Prelude into an emulation of KITT (Knight Industries Two Thousand) from the TV series "Knight Rider". There is going to be a lot of buttons, switches and various indicator lights. I'll add a small screen in the car for both interfacing with the Pi and displaying various data/Images/Videos. Then of course there are the 3 most recognizable traits of the car: The LED "scanner" on the front of the car, the unmistakable voice from the "AI" of the car, and the LED "visualizer" of the cars AI system. Being that I won't be able to make this quite as awe inspiring as the actual KITT and the car I'm using was made in 1999 I'm going to call it the K.I.N.N. (Knight Industries Nineteen Ninety-nine).

  • This is the code for the Raspberry Pi that I used.

    GPIO.setup(24, GPIO.IN, GPIO.PUD_UP)
    GPIO.setup(25, GPIO.OUT)

    scanner = 4
    scan_switch = 15

    GPIO.setup(scanner, GPIO.OUT)
    GPIO.setup(scan_switch, GPIO.IN, GPIO.PUD_UP)

    while True:
    if GPIO.input(scan_switch) == False:
    GPIO.output(scanner, 1)
    else:
    GPIO.output(scanner, 0)

    if (GPIO.input(18) == False):
    GPIO.output(17, 1)
    os.system('mpg123 -q allgo.mp3 &')
    print("All systems go")
    sleep(1)
    GPIO.output(17, 0)

    if (GPIO.input(22) == False):
    GPIO.output(27, 1)
    os.system('mpg123 -q onway.mp3 &')
    print("I'm on my way")
    sleep(1)
    GPIO.output(27, 0)

    if (GPIO.input(24) == False):
    GPIO.output(25, 1)
    os.system('mpg123 -q amuse.mp3 &')
    print("I'm not amused")
    sleep(1)
    GPIO.output(25, 0)

    if (GPIO.input(23) == False):
    os.system('mpg123 -q donttouch.mp3 &')
    print("Something tells me you shouldn't touch turbo-boost")

    sleep(0.1);

  • I finally got KITT "completed". I didn't get nearly the functionality I wanted out of it but it works. I'm going to continue this project after the deadline to get it to a better level of completion for myself. The biggest hurdle in this project was the "Voice modulator". There were a lot of issues in getting both the coding and the circuitry to work properly. It could still use improvement.

  • Some small progress but progress nonetheless. My first GPIO program with a Raspberry Pi for the KITT project working. I took this video a couple of days ago after getting the raspberry pi to switch the "Anamorphic Equalizer" with a rocker switch. I'm currently up to having the programs/buttons for the "Anamorphic Equalizer", the "All systems go", the "Oil Slick", and "Turbo boost". I'm hoping to have the "Voice Modulator" done by the end of day today.
