after some fooling around with methods on how to get done with the technical realization of the project it’s now narrowed down. the installation will use the screen part of an 14” tft monitor, which makes it easy to apply the pictures directly from a pc. furthermore the tft has build in audio speakers which will be used for the sound.
to flash the pictures from the screen onto the retina i’ll be using a photoflash. for the flash to be executed at the right time i am using puredata, which will play the image sequence and sound and is also sending a trigger at the right time to a duemilanove arduino board with an 328 microcontroller chip, which is wired with the photoflash. the script on the arduino is short circuiting the flash to trigger it whenever i say so. by using an optoisolator i’ll be on the safe side not to overload my precious arduino board. thx to riblbem for this wonderfull tutorial!
using pd gives me two advantages. first i can sync the flash with the pictures pretty easy and second i can synchronise the sound to, but still leaving every component discrete though beeing possible to alter them afterwards.
as you can see the setup is pretty simple and so are the scripts, what’s now left to do is to build a decent frame for the tft screen and think about how to attach the flash to it. i also have to find a way how to spread the light of the flash over the whole screen, which maybe works by just putting a sheet of thin paper between the two, but that’s just testing. the tougher part will be now to write the storyline, but that will be the task for next week!
