My uncle was kind enough to build me a circuit that would replicate the left/blue, right/orange portal color switch. He says it is pretty simple but it looks complicated to me.
The heads of the push button switches are painted to be color coordinated to the portal colors. The toggle acts as the main power.
If you were curious, the stand came with my TV which I wall mounted, leaving the stand to be re-purposed. It is only temporary, though. I hope to build one as seen in the game, sometime in the near future.
I left a couple of youngster in charge of photographing last nights show so they were a little too shy to get up in there like I wanted, but here is the relevant stuff they did get.
I got a request to see the light switch function so I recorded this really fast. It's mostly blurry. I'll try to do a better one sometime in the future. YouTube - Portal Gun and Kitties‏
If I should move this over to the junkyard let me know, but this is more of a very informal question:
I've been getting a lot of requests for my blueprint. In my past I've handed out high-res stuff like this willy-nilly only to find them getting sold on ebay, so I am a bit hesitant of letting go of this file so soon. Would there be any interest in a run of prints, 1:1 scale?
