This is the completed front plate of my HAL 9000.
In addition, I achieved a nice effect by lowering the frame rate to 8 fps by using the option “-fps 8”. This file needs to be included as input of the mplayer command “-input file=ttings”. This was fixed by adding a new file “ttings” in my home directory which contained the following The picture of the USB web cam can be displayed on the screen using the “mplayer” command Step 4: display the picture of the USB web cam on the screen Overscan_right=26 # increase if picture flows off to the right Overscan_left=16 # increase if picture flows off to the left The following dimensions are what I decided to use for the panel. In the articles at and other sources on the web you can find slightly different values. The very first step, was to come up with the dimensions for the face plate. So, my HAL is made of wood – and it uses the arcade button for the eye, although with some improvements, as compared to the article. I do not have access to tools for working with metal or aluminum. If, at the first glimpse, people are not able to distinguish my HAL from the original, this is good enough for me. In that spirit, I did not plan to go the extra mile to achieve a 100% replica, but I was happy at the 97% level, if it allowed me to stay on a budget below $100. In the Adfafruit article, they mention the 80/20 Rule (that 80% of a result stem from 20% of the effort). Then, I found an article at in which they build a HAL replica, using a 4-inch Arcade button which looks very close to HAL’s eye. As discussed in the two links above, the original HAL features a rare Nikkor fish-eye 1:8 f=8mm lens which is beyond my budget, and which is not easy to replicate. The most important single detail is, of course, the eye. Great research has been made in a contribution at and another thread on that site has some additional resources on the measurements. On the web, I found some really nice inspirations. The first step was, of course, building the main HAL panel. The whole device is operated by an Arduino and a Raspberry Pi.
My goal was to build a pretty good replica of the HAL panel, and then take some freedom and mount this on a bigger plate that features a few displays and input devices (buttons, joystick).
