How do I brace my garage door so the garage door opener doesn't warp the door where attached to the opener?

I have a one car garage door I'm installing a garage door opener to. The problem is the manufacturer of the door doesn't guarantee the vertical aluminum center bar on the top panel of the door won't bend or break during the operation of the garage door opener. How can I brace the L-shaped aluminum bar to take the stress of the door being automatically lifted without warping the bar or the top panel of the door? There is no information listed on the garage door manufacturer's website.

What could go wrong in a standard garage door opener?

Hello there, I have been asked to try to repair a malfunctioning garage door opener. The man who handed them to me said all of the modules work for a few weeks, then suddenly stop working. I opened them, looking for any burnt component, dry solder joints, tested relays in search of a stuck one, but could find nothing. I tested them at home, and they all reliably clicked their relay on and off, as expected. So the question is, what would cause ordinary garage door openers to fail? I thought about a bad powerline (circuits are 50's era in his building, and have never been redone), but have no means to check it. In the same direction, I was looking for a different model garage door opener, and only found two alternatives: one is the run-of-the-mill SkyLink stuff, expensive, reasonably secure, the other is the dirt cheap Chinese-made remotes with no hint about security. Since this is Instructables, I looked for garage door opener projects, but most are so-called "smart" and need a reliable Internet access, both on the smartphone and on the receiver module. Since this is a multi-tenant building and my country is known to be among the most expensive for internet access 1. there's no easily accessible Internet in the garage 2. drivers can't be assumed to have a smartphone and even if they do, 3. Internet access on a cell phone is extremely expensive. The other question would then be: have any of the community members here saw a garage door opener that would: 1- only need easy-to-make RF remotes? 2- be at least as secure as the original SkyLink? 3- require no Internet access?

Genie model 209 Garage Door Opener schematic

I took our Genie garage door opener apart [the light wasn't working and I read where that was probably caused by the 555 timer] and thought I'd carefully drawn a schematic before doing so, but I failed to label where the 3 wires from the receiver connect to the terminal block on the main unit, and also where the 3 wires from the main unit connect to the terminal block. Regardless, I have the unit back together and when the remote is pressed the receiver relay clicks, but that's the only thing that happens. I'm fairly certain the problem lies with a component on the internal motor controller board. And NO ONE gives out this kind of information. I can't even find it for sale !! But I'll be derned if I'm going to pay $50 for a new controller board when I'm almost 100% certain the problem is a $.59 diode or the like. Plus, I like a challenge and hate getting beat. Any and all help would be very much appreciated. Possibly I could find someone who has the same model unit and they could diagram theirs for me, possibly someone knows where to obtain the real thing. Thanks !!

How can I make a sensor that will turn off my dust collector when the bin is full?

I am installing a cyclone dust collector in my workshop, and I want to make a sensor that will determine when my dust bin is full so that the chips and dust won't overflow into the filters.  I'm thinking garage door sensors could be blocked by sawdust rising into the transparent flex hose between the cyclone and bin, but I'm not sure how they work.  I would use them to turn on a warning light and turn off the dust collector.  Any ideas?  I'm good with tinkering and basic electricity, but am stuck trying to figure this out.

Arduino Garage Door Opener with Adafruit WiFi Shield? Answered

I was hoping to be able to start my WiFi Garage door opener, but I then realized (Well Adafruit told me (http://forums.adafruit.com/viewtopic.php?f=31&t;=44626&p;=225993#p225993)) that their WiFi shield doesn't accept incoming connections :(. They did, however, say that I could use it to set up a UDP server and then send a UDP packet from my phone. Only problem is, I don't know what a UDP server is, or what UDP stands for, as I am extremely new to electronics. My question is, how would I go about doing something like this? Should I just scrap the Adafruit route or is it still relatively simple to do it this way. I am open to all ideas and I don't mind buying another WiFi chip if need be.

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

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!

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?

create hard wired remote garage door opener?

Backstory (feel free to skip) So, my grandparents live in an apartment building and they have to get a daily visit by a nurse for a condition grandma has (it's not going to get away till she passes, so it's not a short-term issue). The apt. building has a big parking lot closed by a remote controlled gate that can only be opened with the transmitter -the tiny one you hook to your keychain-. The nurse gets there by car and it is not possible to leave it on the side of the road so my grandfather is forced to go out, get to the ground floor, walk around the building and open the gate with the remote, this is really time-wasteful so I tried opening the gate from the balcony but the transmitter hasn't got nearly enough juice toget the signal to the receiver, on top of the fact that they're on the wrong side of the building. End Backstory So, I was set on buying something AC powered, with a seriously extended range, that might send the signal there, but could not find anything.  Could any of you educate me on ho to build / mod something like that? thank you all in advance

Sense when garage door is open. Light/LED light turns on?

Hi there, I have an automatic garage. But sometimes i forget to close it and it stays open all night. Apart from someone being able to steal stuff, it would also allow an intruder into the house while we are asleep! So what I am looking to do is whenever the door is open, that a light inside the house turns on. My garage door is a panel lift door. My initial thought was to use alarm sensors. One on the wall and one on the door. If the sensors are not near each other, a light in the house should turn on. The serial circuit would look something like the following. GarageDoor > GarageDoorSensor > Less than an inch of air/space > WallFixedSensor > Wire > CentralLogicDeviceWithBattery > Wire > TinyLight/Led. The hardest bit would be what I have called the CentralLogicDeviceWithBattery. I would like to know what parts i would need and which part connects to which part. thank you

Safety of your garage door or car remote...

No time and no pics for a proper Instructable, so I just put out some word of warning ;) Around here bad people take advantage of the fact that a lot of new houses have the garage right next to the house. With these you usually also get a door so when you park your car you don't have to get out of the garage again. All controlled by the press of a button on the remote... Some fancy guys got a device working similar to the IM-ME Open Sesame hack a few years back. But unlike the original author the new guys found ways to make money by providing working "universal garage door openers" on dubious websites. Problem with the new model is that it not only fakes a remote with dip switches but also the newer models with so called "rolling code", "intellicode", "changing code" and so on. The old remotes with dip switches should actually by phased out years ago by any owner who values his stuff... But the new models are still deemed secure and next to impossible to hack - well if you trust the advertisement... How does the code hacking work? The old dip switch models allow for a maximum of just over 4000 different codes and come in just 3 or 4 frequency bands. No real problem for anyone with basic electronic and coding skills to hack these - as shown with Open Sesame. The new models all use a so called rolling code, here the remote and opener are paired through 32 bit of ID code and an encrypted part that changes every time. Both remote and opener calculate the next code once a button was pressed or a code received. To overcome reception problems the base usually calculates the next 256 codes in advance - and that is the entry point for bad boys. The illegal device scrambles the frequency detected while storing the code received by the orignal remote. As the door did not open the owner will try to press the button again. Still scrambled to opener does nothing - until the device sends out the first recorded code! Now the owner can drive in and is happy. Of course he still needs to close the garage - again all is scrambled and the code stored as before. You see where this is going.... It is even possible to set the amount of required tries to capture, so in theory a bad guy could get the next 10 or codes in advance for use once the owner is gone out... Worst thing however is that these illegal devices not only open garage doors but also cars as a lot of them use similar systems for their remotes - up to the point of starting the car with it. Took me only 2 hours with Google translate to find a website outside the usual search results that offers these "gadgets", along with WiFi and cell phone jammers, credit card copy devices and more things I don't want know about... What can you do to protect yourself? First check what type of remote your system uses - if there are DIP Switches than replace the remote system or the entire device in favour for something more secure. If you already have a rolling code model that you are far better off but sadly no longer totally safe here. A lost remote should not only be replaced but the old one removed from the system as well - you never know if you just lost it or someone took your remote ;) Alternatives exist, especially if you are not afraid of doing some open heart surgery on the electronics of a garage door opener. You can add a WiFi module and use your mobile phone to open the garage - search Google if you like the idea ;) Another very neat way is using a second transmitter that keeps the relay for activating the opener from working. This can be anything from a BT module paired with your phone or cars BT system over a keycard to numberplate recognition cams. A good system also allows for a "holiday mode" or similar. Here you can set this mode with one remote until you deactivate it with the same remote the system will not react to anything. Great if you leave the house for more than a day or two... As a last resort you can always get a big and angry dog to sleep in your garage.... What if you are renting or a bit limited with the electronics and soldering skills? Not all is lost if you can accept a second remote for added safety. These days you can get plug in converters for your mains voltage outlets that work with a remote control. Unless they use Infra Red for this they are great to disable your opener. Simply plug it in where the power cord for the opener is and then plug the cord into it as well ;) Now you can fully shut off the opener with the press of a button and only if the power outlet is switched on the opener will work. If in doubt you can use a double outlet adapter an extension cord and a night light to indicate wether or not the opener has power. Ok, and what about the door lading from the garage into the house? Well, of course keep it locked and if you are home also keep it locked. At least this way you have some extra time in case someone tries to enter through your garage while you are sleeping ;)

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

How can I open and close a window that works on a roller from left to right?

The house we have incorporates a security panel that prevents would be thieves from breaking in. My mother is close to 70 and from the kitchen counter the door I am trying to open and close is 38" from the edge of the counter. She is 5'6 and does not have the energy to slide the door open. She usually unlocks the door and then steps outside on to the balcony and opens it from there. I want to find a way to make it electric if possible. I haven't finished the tilework so I can still run electrical lines and switches to the area. The best idea I can come up with 12v automotive power window motor that is mounted on the right side of the opening. A dog ear be mounted on the top part of the opening for support, and a dog ear be mounted on the door...just right of the LEFT dog ear support itself which will have motion. Attach (weld) a screw onto the power window motor. When engaging the window motor to open the threaded rod revolves in place and the door opens. Same happens when the door closes. My problem for when the door is ACTUALLY supposed to stop in order to be locked by the built in handle. It needs a limiting switch that is engaged to cut power when the proper distance has been traveled. I got this idea from my gate opener for my driveway, the only difference there is that it operates on a chain and has 2 limiting switches for open and close. My father wants to go a simple route and put a pulley on each side of the window and if you want to open / close the window you pull the appropriate line. I just see that as ugly and will be breaking eventually.

How can I open and insulate a single heavy wood sided garage door not using an electric opener or traditional hardware?

I have 3 single, older, traditional wood-sided garage doors. I am making a room out of the garage and, fixing 2 doors, but still want 1 door to open. Each door is 8'Wx7'H with 5" horizontal T&G siding. I planned to add some 24"x14" wood window sashes across the top, add insulation and some kind of thin paneling, doorskin or such to the back side and trim out the front side with 1/2" x 3" redwood. The fixed doors are no real issue, but what I'm puzzling about is how to make one door openable, but yet weatherized, and without all the traditional opening hardware showing inside. The windows & their framing, the trim, and  back panels will add weight, maybe alot. I want to remove all the exsisting spring hardware, so it looks like a room inside and not a garage. I thought about some kind of block & tackle, or manual gears to lift the door, but I just don't know. Also, I want to keep the doors appearing on the outside like regular doors, but modernized, and all 3 the same. Any ideas, (wild or otherwise, I'm open) to lift and open a door like this? I considered remaking the doors into carriage doors, but my driveway is sloped, so that could be a problem for rollers and any type of weatherproofing. I wanted to avoid completely remaking the doors any more than I already am. Thanks for any ideas.

Please help with 1st arduino project

I love this site, and have been totally inspired by many of the projects I see on here, thank you to everyone who takes the time to post their work here. I'm trying to get into my first arduino project and am just looking for some help getting started.  Like many other people, my wife/kids (never me) tend to leave the garage door open, and I was looking for an inexpensive way to build a monitor, using an arduino board. Joe's garage monitor seems really great (https://www.instructables.com/id/Garage-Monitor-3001/#step1), but the post is a little old, and some of the parts listed do not look like they are available anymore. And it may be too much, I can connect this sensor to my home network (since my garage is next to my home's boiler room where all my networking is wired to). So basically I am thinking of the magentic sensors (http://www.dinodirect.com/Plastic-Door-Magnetic-Sensor-Alarm-Security-System-MC-31.html) on the grage door to indicate open/closed, which are only a few dollars, and then somehow connecting that to an arduino board, and then patch the board to my home network where I can log the status to a database. any help with suggestions for an inexpensive board to get started, is greatly appreciated, thanks!

How to connect a garage door photo eye to a micro?

I am looking at hooking up an old photo eye from a garage door to a micro. The end use will be in a device to detect if my dog is about to jump over the fence and take a picture as well as play some audio of me telling him to get down. The problem is that I don't know the correct way to connect the photo eye to the micro. I believe the transmitter site should be powered with 12V, but I would rather know for sure before frying the sensor. My garage door opener doesn't have a port for the photo eyes, so I can't check the outputs on it, but I was hoping someone here might already know, or might investigate their own open. Thanks for any help.

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.

How do you close a door from bed - whether it opens in or out! Could use a solution for bedtime! Answered

My dilemma - and if my wife would let me solve it in our bedroom is I get in bed and the bathroom door or the door the hallway is open.  Sometimes the air pressure swings one or the other closed/open - but regardless I hate getting out of bed to close them. Anyone got any creative ways of a build to close them?

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
