See how we built it, including our materials, code, and supplemental instructions, on Hackster.io: www.hackster.i...
In this video, we show you how to make a smartphone-controlled, internet-connected deadbolt actuator powered by a Raspberry Pi that can be added onto your existing door lock without any modifications to the door. The door lock can be controlled by multiple smartphones, and even notify you whenever someone locks/unlocks the door. All of this is done using a simple, drag-and-drop app builder (www.blynk.cc/) which makes building your own Internet of Things (IoT) app easier than ever. For an extra impressive door lock, we'll also show you how to add a simple LED light to indicate if the door is locked, and a push-button to operate the lock manually.

Little overkill with a Pi. ESP8266 with sleep mode and 18650 would be nice so you don't need a charger all the time.

Guys, I just stumbled onto your site today. You two rock! This is a GREAT site. I am pretty obsessed with home automation and seeing what home users can accomplish. I love that you guys are giving us great tools and the projects are in stable shape. Seriously making them pretty and hiding wires and painting cables.. I would rather we do that and you guys concentrate on the bones and muscle of the projects. (I am just putting that in cause amazed when people are complaining about "I see wires!!!!". They should know how to hide a wire!) I am looking back now at your project list for fun cool ideas! you ROCK!

@calendil 4 жыл бұрын

A couple of suggestions to improve your project: couple the servo with a gear and put a thru shaft. Gear should engage to the shaft on shaft's axial movement (like a car gear box). Put a handle to the back end of the shaft and a spring which would push the shaft towards gear. When someone pushes the handle from inside that would disengage the gear, and you can lock/unlock the door manually by the handle. I hope this makes sense.

could you have a small onboard battery that could power the pi for a few minutes and then some contacts on the top of the door to transmit power when closed? that way wires could be routed in different directions.

Yeah this is nice, good work by the way, but there are door jam bolt release mechanisms that you don't have to make any 3d printed stuff. They don't cost much either. You can have the wire hidden behind the trim boards. And by using an MHCOZY smart switch you don't have to do ANY arduino programming. You can even use the Bluetooth function on the MHCOZY to open the door when your phone is close to the door.

You can also have gaagle's always listening function to unlock the door when you say "Hay gaagle unlock my front door.". For those times you're holding a bunch of groceries.

OK. Spitballing an idea here. Could we use this architecture to control a 3 position switch? I am in the formative stages of an idea here where you use a Raspberry Pi to control and turn a generator off and on based on the power level of the battery back-up. Battery hits 30%? Electric Start Generator turns on. Battery hits 100%? Generator is switched off. I'd also like to have a notification sent to my smart phone if the generator is turned on, thereby alerting me to power outages when I am not present in the building. And possibly scheduling regular weekly maintenance by switching itself on and off for a short period of time each week. Oh, and possibly attaching a small LED screen to show the battery backup power levels as read by the pi. The practical upshot is that during a blackout, all devices can stay powered even in the absence of staffing. My biggest concern is in the servo being able to switch the key from off to on to start and back to on.

How did you go with this project, did you follow through? I'm in a similar position with need for a device like this

@haydo8373 5 жыл бұрын

You would be much better off by removing the mechanical element of this design. Just use a couple of relays to control starting the generator. You should probably use a sensor to detect when the generator is running to disengage the starter motor. You would also want to prevent the start engaging when the unit is already running. This could be achieved multiple ways.

lankyfingers If the lock was activated by a voice controlled script, it would most likely be behind a sound proof door, with the mic facing inside the house, and not outside. If you wanted a voice unlock outside, you could even program it to only unlock when a certain voice is heard.

For doors with not a turning handle on the outside, would it be possible to remove the door knob lock (we call it tongue in my country, I am talking about the thing that closes and opens when you turn the door knob). Remove it or replace it with one that opens and closes with some basic force then have an external lock that has a female insert screwed on the door and a male remote controled piece on the wall that locks the door tightly closed using the app. that way you can still use your doors lock system and as a backup and keep that unlocked when you want to remotely open the door by opening the external mechanism.

I'm seeing this several years after it was made and I'm trying to think of how it could be miniaturized even further. If you used an ESP8266 you could put a battery on board to run the ESP and then you wouldn't have wires running from the Pi to a power source.

Could you add another button on the case that is programmed to lock or unlock the door depending on which state it is in? I don't know too much about this kind of stuff but for sure want to learn about it. The servo is it always in one place until told to be moved or can it be freely turned as you want but moves when it is told to? If it can be moved freely an opening could be made on the casing so you could reach a finger in a turn the lock physically right? Also, does the servo keep track of how much it has turned or is it just a motor that moves when it is told? I would love to learn about this so if you have any knowledge to share please do so! Thanks.

You should be able to design it so you can use the servo and the key to open and close the lock. You just need to have a slack between the servo and the lock turn. Like let the servo lock with a fork on the original manual lock turn.
