RPi 9000

Voice controlled HAL9000 replica powered by Raspberry PI and Jasper

Similar projects worth following
This project uses a Raspberry PI computer with some of-the-shelf computer components, and a custom acrylic box to create HAL9000, the iconic computer from Stanley Kubrick's 2001: A Space Odyssey, so perfectly portrayed by the voice of Douglas Rain.

It uses for voice input, and I wrote several modules for it ( including a MQTT client, which allows me to control other MQTT enabled devices in my home.

Total cost for this build is ~$100, and you can find the Bill of Materials document here:

    What We'll Need

    We will need:

    • Raspberry PI 2 Model B ($25)
    • Raspberry PI Power Cord ($5)
    • WiFi USB with Antenna for Raspberry Pi ($9)
    • Used Titanium Super Wide Lens 0.42x AF (~$4)
    • Metallic Spray Paint (~$4)
    • Generic 7.1 Channel USB External Sound Card (~$4)
    • Used Insten USB Digital 6 LED Webcam (~$4)
    • Wireless Portable Mini Speaker ($10)
    • 3mm(1/8") Cast Acrylic Sheet - black - A3 Size (2 x $10 = $20)

    I also had to pay for:

    • Laser cutting service ($10)
    • Shipping and postage ($5)

    Which is a total of $100. You can probably go cheaper than that, if you find/have any used components.

    Cutting the Acrylic (Plexiglass) Case

    The case can be ordered from (they are free I don't earn from the sales it's just a convenient for someone to order them). You can always use the supplied plans to cut the acrylic/plexiglass yourself.

    I've used a 3mm thick cast black acrylic. Once you peel off the protective layers (NOTE: don't peel them off until you've assembled the box), it is actually 2.9mm thick, and the box plans were constructed using that thickness, and it turned out really nice.

    The diameter of the lens that I've used (Titanium Super Wide Lens 0.42x AF) is 56.8mm, but the diameter in the plans is actually 56.7mm to compensate for the width of the laser beam and the acrylic that melts around it. In my original design I've used 56.55mm and the fitting was too tight, I had to sand off 1/10th of a millimeter in order to fit the lens through.

    To open .dxf and .dwg files you would need AutoCAD, but you can also use DraftSight - which is a great, free, alternative.

    Spray Paint the Metallic Parts

    The thin frame on the front and the perforated bottom part of the front face should appear metallic. Use an exacto knife to separate the acrylic protective layer of the perforated bottom part and peel it off before you spray-paint it, so that only the bottom layer gets painted in metallic, and the top part doesn't since it'll still have the protective layer on.


    • Shake the spray can really well.
    • Keep the nozzle at least 1 foot away from the object that you are painting
    • Paint always in the same direction
    • For the best results, paint with the fine mist, in several layers
    • Wait for 20mins before applying another layer
