yeah its on sale.Well. Think about this. Im going to need electricity for up to 10 seconds.
I mean that will last a bit of time. Especially because I have 451 AA batteries in the same place. (According to my battery dispenser I built c;)
Why the forget you need a dispencer lol?
i said up to.
And it wont even open it all the way. It wil probably take about 3-5 seconds. Depending on how my dad will spend on a motor.
If I can get a good motor, Then I can probably open it faster than you can.
I guess you like building stuff for fun.
I wish I could have done that when I was a kid, hope it works.
As for gears, you have to actually think this through, how woud gears open a door, you'd need to put a quarter gear glued/bonded to the door, and a gear next to it, that was on the moter, mounted to the wall.
Probably won't take a day of work, but your door and wall will have stuff stuck to it.
