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

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.

Indoor buzzing door opener with multiple openers

Hey guys, i would really like to have an instruction on how to install and customize a buzzing door opener. i´m kinda a lazy person and i want others to respect my privacy. My family is constantly rushing into my room in the most...lets say awkward situations :D I want the door to my room just to open from the inside or from the outside when pushing the open button. On should be near my pc and one should be near my bed. This would work perfectly if i get one of this buzzing door openers which are used to open the main door to the house. But i dont wanna replace my hole door. Just the metal part where the lock is. Also it would be neat if the openers where wireless. And the lock should work like a normal lock: I put in the key and i come in from the outside like a normal door =) Any one brave enough to take this challenge?

How to keep door ajar for winter. Cat keeps opening it.

Winter is approaching in Australia. I work in my home office and my computers and sometimes heater [or bread machine :)] keep the office warm. My cat likes to visit for a scratch several times a day. For this, the door must be openable otherwise i have to let the cat in and out. I have been keeping the door nearly closed which keeps the warmth in. However, my cat arrives and virtually bashes it open. The heat in the room is sucked out within minutes if I am distracted by work enough to not close the door ajar on entry or exit of cat. How can I add an upgrade to the door which will keep it closed-ajar if a cat or human uses the door. I would like to solution that can be disabled as in summer I would like the door to be open (which is working and does not need a solution to keep it open). The door is on equal balance (if that makes sense) and I would not like to modify the door hinges. (I had attached an image but must not have enough trust with this site for it to display). The door is a colonial door if you see pictures on google images.

Where can I get a schematic for a Chamberlain 5200 UBC garage door opener ?

I know the remote control is working as when I push the open/close button I can go on the main cct. board and see the signal on pin 14 of the LM2902. I can also trace the signal to pin 12 of the micro. The micro should do several things,  check whether the door is open or closed, apply power to the relay motor, apply power to the relay motor to open or close the door. The controller works in the manual mode ok, i.e. I can open or close the door, turn on or off the light. It is very difficult to trace the circuit board as it has a ground plane on the top of the board and SM components on the bottom side of the board. I am unsure of two things, first the signal going to the micio is about 1 Vpk-pk and not the normal logic level or 0 and 5v, but if this input to the micro is set as an analog signal then level may not be an issue. Secondly I cannot determine what output pins on the micro control the power relays as it is almost impossible to trace the cct.    Anyway any help would be greatly appreciated ... thanks in advance and take care ...Vic

What is this?

We spent a week at a beach house.  In the photo, you see a device attached to a door. There were several of them attached to doors throughout the house. It's a hollow steel ball attached to an arm, which was attached to the door. It could move back and forth like a pendulum, but it rubs against the door and doesn't move freely. You can see the rub marks on the door. So it didn't swing by simply opening or closing the door. This photo was taken in 2003 and I still don't know what it is or what purpose it served. If you know what it is, please leave a comment.

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.
