Puertas Neumaticas

Es habitual en Star Trek (y Star Wars) que las estancias se separan por unas puertas que se abren y se cierran automáticamente.
Esos mecanismos han dado momentos de gloria en el cine a cuenta de atrapar en medio a quien no debían o cuando no debían, así como por abrirse y cerrarse en los momentos más inapropiados. Pues ha llegado el momento de que estos innegables avances técnicos lleguen a tucasa, ya estás tardando en instalar en tu dormitorio una puerta de accionamiento neumático como la que aparece en el vídeo. ¿Deseas saber más?
Sensor biométrico, mecanismo empotrado de apertura por aire comprimido, rejilla de ventilación para expulsión del aire… y un sonido que nos remite a los mejores momentos del cine de ciencia-ficción… o al metro y el autobús que te llevan a currar a diario.Este chico del vídeo nos muestra orgulloso la instalación de unas puertas corredizas por aire comprimido que a pesar de su inspiración tan galáctica no desentonan en absoluto con la decoración tan clásica de su domicilio. Incluso el sensor de la huella dactilar que autoriza la entrada está integrado a la perfección con los apliques de la pared.

I haven't posted much recently because I'm working on a few projects that aren't complete yet and I would rather wait to post them after they're further along. But in the next few posts I'm going to be digging up an old project I finished overfour years ago, which I am going to enter into the Craftsman Tools Contest. I'm also going to talk about my ongoing work on the project, trying to turn it into a viable product.

When I was younger, one of my favorite shows to watch was Star Trek: The Next Generation. I also visited Disney World about once a year with my family, and my favorite "ride" has always been the monorail. It isjust an icon of all that is futuristic. To think that it was built almost 40 years ago is amazing.

I always wanted a piece of Star Trek and the Disney Monorail in my house, and one thing they have in common is that they both have automatic sliding doors. It would be the perfect, most geek-ified entryway for my bedroom. Only oneproblem: I was still in school and still lived at home with my mother in New Orleans. I had tried to convince her for years that installing a Star Trek Door would be a good idea, but it never happened. It wasn't until we were renovating our house after Hurricane Katrina that she finally caved in. There wouldn't be a better time to do it.

To be acceptable as a permanent renovation to ourhouse, I knew the door had to have a normal appearance, as well as be practical and maintenance free. To reduce the number of moving parts (and maybe for a little coolness factor) I decided to make the door air-powered. The air would be supplied by a small compressor and storage tank located in the attic. In order to open and close from the inside and out, the door needed a little bit ofbrainpower. I decided to use a small PIC microcontroller, my platform of choice still to this day. Arduino didn't exist back then.

With a rough plan in my head, I drew a quick CAD model of the door and the brackets that would connect the pistons to the door halves. I was ready to start purchasing parts:
• Small air compressor with tank from Home Depot
• 32" wide, solid wood door from Home Depot...
