Garage door Answered

Ok, so I've about had it with my garage door opener. It's supposed to sense when objects are underneath it and retract from closing, but it doesn't. I want to replace it, please recommend me an option that actually works. I have two kids and they leave their toys all over, that door would eventually either wreck their toys or worse, hurt my kids. Thanks in advance!

Hidden Door/Bookcase

I have a "man cave", as my wife calls it. It's basically my office, with all the decorations she won't let me put in the rest of the house along with my Ammunition Reloading Bench....anyway, there is no door. The hallway opens right into it.  I have a curtain there now but I have always wanted a secret door. I have looked at all the "instructables" pertaining to the hidden door, however I can't figure out what kind of door is a good door or where the hinges go or if i should use a pre-existing bookcase...any suggestions?

Remote Doggy Door?

Not looking for an automatic door such as where the dog's RFID gives auto entry, but looking for a way to keep my dogs in my house when I leave via my car in the garage. Looking for some type of remote controlled thingamajig to keep their doggy door closed or secured while I'm in my car pulling out of the garage, and then once my garage door is closed give them access to the garage. Only a problem when I leave for the day, when I return at night they're so happy to see me they're not in a mood to go run off when the garage door opens.

Hidden Door Latch

I am looking for a secret "latch" to open/close a bookcase that covers a hidden door. There are some nice electromagnet types but they are expensive and need power. Any ideas on a "Chinese puzzle" type of thing where you move a couple of things and it opens? I don't want the classic horror movie things like move a book, lever or statue 'cause that's the first thing someone would try. Just fishing for ideas!

Retractable door screen

Hi, It's just coming on to nice warm weather here in Australia and the flies are pretty bad. We have an odd situation with our front door in that there's this wooden beam supporting part of the roof that comes across low. This makes it impossible to have a screen door that opens outward (the main door opens inward). My son suggested that we get some sort of retractable screen, but they are so $$. Does anyone know of instructions for how to make your own? Perhaps something that retracts on a vertical roller on one side and when open, it seals tight on the other side with a magnet strip. Thanks, ebb_AU

Doors and WIndows Automation

Hello, I am trying to automate the windows and doors in our barn using NEMA  stepper motor and Lead screw and would like to exert around 20 Kg force for opening or closing. The windows are fairly old and made of wrought Iron. I am wondering if somebody can advise and help me selecting the motor (based on torque) and the appropriate diameter of the Lead screw for this instance.  The idea being that when the lead screw rotates, the ball nut flange moves left or right and pushes the connecting rod out or in thus opening or closing the window I have attached a rough sketch what I had in mind and please pardon me for any mistakes. Many Thanks Ash

Question by teabreak  


Energy Efficient Dog Door

Winter is coming and I have four dogs and two cats. We installed a dog door to the outside some time ago, but it's a big air leak. Even though we replace the door every six months, it's only plastic with magnets on the edges, and doesn't always fall back into place. I've tried various solutions, but what I really need is a solid door that locks into place, or a door that opens and closes with a trigger. Automatic dog doors cost about $350.00 - $450.00, and require the dog wears a special collar. I'm not looking for security, I'm looking for energy efficiency. Can someone please help? I know there are lots of others in the same position.

cat running out the door

I'm looking for a device to stop my mom's cat from darting out the door.  My mom is 78 yo. and doesn't react especially fast.  I'm wanting some sort of electric mat that will only be activated when the one cat is on or near it.  The door is used constantly by humans and the dog uses the door also.  Therefore, it can't be activated by stepping on the mat.  I'm thinking of a collar device that the cat would wear that activates the mat or activates a air burst or sprayer, etc. Any ideas?

Automated Garage Door Timer

I have the bad habit of leaving my garage door open sometimes. To come home with your garage wide open is pretty scary. So I was thinking of this idea...  The garage automatically closes after 5 minutes. But that's pretty annoying so I figured you could install a switch underneath the garage door opener that will leave the garage door open. Any ideas on how this could be done or more suggestions? Thanks!

Opening and closing a small door

I want to build a small cabinet based on the TARDIS. I want the doors to open and close automatically and, of course, make the sound. It will only by 12 or so inches tall so I don't need anything big to do this. Ideally, I'd like to activate it by touch. My first idea was to start with the wiring for The Most Useless Machine and move on from there. Think that's a good start? Any better ideas on how to do it? The full build will be in an instructable.

Garage door safety sensor wiring?

I believe it is an infrared sensor with two wires on each. I have wired them to a 120V plug and the LEDs on them turn on and my motor spins slightly (probably just because it is a 120V motor and it's not getting enough electricity) but I try to line up the sensors and they do nothing different even when crossed. What I want to happen is for the motor to remain off until the beam is crossed. Once crossed I want it to spin and to keep spinning until I disconnect it. I would really like to put an alarm on it so when crossed an alarm goes off. Does anyone know the additional things I need and how to wire them? Thanks

Modding High-end pet door

I currently own and am using a High Tech Pet electronic pet door (http://www.hitecpet.com/px-1detail.html) and would like to modify it to: 1) Read/activate via a small RFID tag instead of the very large (for a cat) sonic transmitter. The cat is feral (we lock him at night in the garage), so he sometimes gets in fights and loses his entire collar. The transmitters are $40 each! He's lost three so far. 2) Switch mode to "in only" at a preset time very night and "in and out" mode every morning. I like the features of this door, and it's already installed. It's extremely weatherproof and resilient. Most Lexan/acrylic cat flaps I've seen or owned aren't even in the same league as this one, which is why I would prefer to keep this door as opposed to modding a different brand of door. I know how to solder and have a very basic understanding of electronics. I could probably muddle through a DIY, but I'm not even sure it can be done. Is it as simple as locating the receiver on the board and replacing it with an RFID reader? Or is that wishful thinking? Thanks in advance for any insight, advice, help. :)

Building boxes to fit existing doors

I have about five Tasmanian Oak cupboard doors and they are an odd size (W:490cm x H:575cm). I want to use some of them on low-hung overhead cupboards in the kitchen. They have a board insert with a plan board on top and sides. They would look good, I think, just lightly stained and sealed or painted white in the farmhouse style. Problem is, because they are not a standard size and I cannot by stock cupboards to fit. I thought I could buy mdf or pine boxes to attach them to but the odd size makes this difficult too. So then I thought - I will have to build them myself. As I am a total novice, does anyone know how I can do this, tactically and in the most economic way? Thank you in advance ...
