Quoted from harryhoudini:You're probably talking about $300 or more when all said and done. You'll need more power than an arduino to drive video. Probably use something like a 4D systems screen (like is used in the WOZ crystal ball) which is going to hit you around $100 off the bat, probably more. The tiny one in Woz is like $50. Those have a processor built in and external triggers for events to run video clips. You'll need to design a mount for the screen, a shield for some sort of micro controller (arduino or Pi), programming on both the screen and the controller, etc
That sounds way more complicated than it needs to be. You can get a 4D smart display for as little ad $30. It can accept input triggers on it's own without the need for arduino or other microcontroller. It has SD card slot on it to store the video or animation. For this application a single video or animation of a swirling portal should be all you need. Then you just need to mount it to the ceiling of the garage which could be as simple as a laser cut piece if plastic. I'm thinking closer to 100 for a plug and play solution that triggers off an existing insert or light to turn on portal animation.
I think the peppers ghost effect wouldnt look as good as just having 2 way mirror film on the garage floor plastic. The peppers ghost effect would not be as bright and visible as a direct reflection onto a mirrored garage floor. The 2 way film could reflect the portal animation from the ceiling display and also let lights from below the floor plastic shine through on the edges.
All this would of course depend on what kind of lighting effects spooky already has that we have yet to see. Since Scott loves cool light shows he might already have something there that looks great as is.
If you look at the under playfield pic, it looks like there's a lot going on in that corner where the portal is. Might already be a bunch if stuff in the garage ceiling.
