I am mentally stuck on a problem I KNOW I should be able to do mecanically, sometimes I think I have a solution, but then it evades again.
This has nothing to do with Parallax nor electronics, but if lost I search the help of the brightest people I know, and they are here.
Lets imagine a standard off the shelf carport, one of those tent like metal frame with plastic foil over it. You know them. This one has some sort of Garage Door, two zippers, one left, one right and a flap in between one can then - hmm - wrap up with some bungie cord or so.
I put a metal pipe on the bottom, so I can - sort of - roll it up. Doing so I noticed that when I might be able to attach the zippers to the pipe, I could roll it up or down and the zippers would follow.
That part was easy, longer pipe, rubber-band.
Now the part where I am stuck.
Direct in front of the carport is a automated gate. its about a inch away from the flap, the zippers and my pipe on the bottom of the flap/garage door.
And I keep thinking that there SHOULD be a way to mount some steel wire to the gate, route it SOMEHOW to a ring with a spring at some usable place to hold tension so that when the gate is opening it rolls my flap up and when it closes it rolls my flap down.
Sure I could build just a separate system, another motor, that rolling up and down is mostly solved, but yeah somehow I almost have a more beautiful pure mechanical solution and then I get stuck.
Open for any inspirations how to solve the SOMEHOW, there is not really a NEED for it, it just bothers me...
