One of the things that I kept on thinking about in Gravity Falls is the vending machine.
How did it came to be? Did Ford had a vending machine before? Why would he keep a vending machine as a door then? You need money to use a vending machine and this is home. There is no point in keeping a vending machine.
Now re-watching a tale of two stans, we see this:
The door on the left is probably what leads to the basement considering this is the gift shop (right?). There is NO vending machine. Now the question is, who put it there? It has to be someone who is great at engineering.
Fiddleford? Maybe. But how did Stan convinced him to build it then?
Stan probably has no idea about the society of the Blind Eye so he can't just ask a person to build him a secret vending machine door that responds to the code of the door and then erase their memory.
So I'm thinking three things here:
During the shack's construction, he was able to fool (bribe) the workers in to doing what they're told without question
He really did re-wired everything by himself based the books he (forced himself to) read or;
He did it accidentally by doing random re-wiring by himself and by a stroke of luck, it worked.
1 is most likely what happened but 3 can be acknowledged. If it's 2, then it really proves that Stan is smart without him knowing.
Maybe this idea has been answered by Hirsch already and I just didn't know. Feel free to explain it to me and I'll delete this post.
