Raspberry Pi Controlled Chicken Door

April 11, 2015 by 18 Comments

We’re not sure if the Chickens know it yet, but they could be one of the reasons for all this IoT craze now a days. Look for chicken coop, and out come dozens of posts from the Hackaday chest.

Here’s another one from self confessed lazy engineer [Eric]. He didn’t want to wake up early to let his chickens out in the morning, or walk out to the coop to lock them up for the night to protect them from predators like Foxes, Raccoons and Opossum. So he built a Raspberry-Pi controlled chicken coop door that automates locking and unlocking. The details are clear from his video which you can watch after the break. The door mechanism looks inspired from an earlier anti-Raccoon gravity assist door.

The hardware (jpg image) is simple – a couple of hall sensors that detect the open/close status of the coop door that is driven by a DC motor via a bridge controller. The whole setup is controlled using a Raspberry-Pi and this is where the fun starts – because he can now add in all kinds of “feature creep”. Motion sensor, camera, light array, and anti-predator gizmos are all on his drawing board at the moment. Add in your feature requests in the comments below and let’s see if [Eric] can build the most advanced, complicated, gizmo filled chicken coop in the Universe. Combine that with this design, and it could even turn out to be the most beautiful too.

Irising Chicken Coop Door

July 15, 2017 by 26 Comments

What’s cooler than a door that irises open and closed? Not much. They add a nice science-fictiony detail to any entryway. [Zposner]’s dad wanted an automatic door for his chicken coop, so [zposner] took some time and came up with a nice door for him with an iris mechanism. You’ll need to watch the video.

[Zposner] used a combination of laser cutting and a CNC router to cut the pieces, then sanded and painted the wood. After assembly, [zposner] started work on the control mechanism. He’s controlling the door with an Arduino and a motor shield; to let the Arduino know to stop the motor, [zposner] used limit switches which get hit as the mechanism rotates. Once the switches were in the right place and the code written, it was time to finish assembly and install the door on the coop. To keep the Arduino that safe, it was installed in a plastic container with a screw lid, and then hot-glued to beside the iris.

Unfortunately, chickens don’t necessarily care how cool something is, and in this case, they didn’t realize that the iris was a door – they refused to exit the coop through it. [Zposner] tried a few things before settling on putting the chicken on the edge of the door – then the chicken would realize that it could go through it.

[Zposner]’s dad now has a snazzy door that opens with a switch. It was a great project for [zposner] and his dad to work on and, even if the chickens seem unimpressed, they did a great job. Check out the iris porthole that a Detroit Hackerspace built into its door, or, if you really want to build an iris mechanism, but don’t have access to a CNC router, a laser cutter, or, you know, wood, you could build this out of bits you have lying around.

IoT Coop Door Cares For Chickens, Tests Home Automation

November 6, 2016 by 28 Comments

Most chickens are pretty good at putting themselves to bed when the sun sets, and [Eddy]’s chickens are no exception. But they’re not terribly thoughtful about closing up after themselves, so he set about on a long-term project to automate the door of their coop.

An open door overnight leaves chickens and their food vulnerable to predation. Rather than handle the chore manually and risk one forgetful moment that could wipe out his flock, [Eddy] used a servo to power the door and an Arduino to control it. To keep track of bedtime and wakeup, a Raspberry Pi looks up the local civil dawn and twilight times online and tells the Arduino when the moment is at hand. The Pi cleverly caches the times for use the next day in case the WiFi connection is down, and also provides a web interface to check on the door’s status and manually override the cycle. Result: safe, happy chickens.

If all this seems a bit much for a simple job, [Eddy] agrees. But he’s using this as a testbed to develop a home automation framework that can be retasked at will. Sounds like he’s on the right track to us, but for more IoT animal husbandry tips, he’ll want to check out this small farm automation effort.

Chicken Coop Door Using Threaded Rod

May 1, 2012 by 19 Comments

There’s no rooster to wake them up, and [Steve] and his wife are fine with that. What they’re not fine with is having to get up early anyway in order to let the chickens out of the coop. Like many small-scale egg farmers they sought out an automatic solution for opening the coup in the morning.

[Steve] had seen a bunch of different automatic coup door hacks kicking around the Internet. But all of the ones he could find used a vertical door and pulleys. His setup has a door that opens horizontally and he realized that he needed to build some kind of linear actuator. What he came up with is a system built with hardware store parts. He’s using a plain old piece of threaded rod along with a coupling nut (they’re usually 3/4″ long or so). The nut is held firmly on the door using a conduit mounting bracket, while the threaded rod is turned by an electric screwdriver mounted to the jamb. Two limiting switches are made up of magnetic sensors often used to ring the door entry bell when you enter a store. An Arduino takes care of scheduling and controlling the motor for opening and closing the door. See for yourself in the high-production-value video after the break.

For what it’s worth, we have seen at least one rope and pulley door that slides horizontally.

Motorized Coop Door Lets The Chickens Out For You

September 16, 2011 by 19 Comments

[Larry] and [Carol] just upgraded the coop to make their lives easier, and to help keep the chickens happy. The image above is a chicken’s-eye-view of the newly installed automatic door. It’s a guillotine design that uses the weight of the aluminum plate door to make sure predators can’t get in at night. This is much easier to fabricate than a locking coop door would have been. Some leftover aluminum channel guides the door on either side, with a spool above it to wind up some rope, thereby lifting the door.

You can see the belt-drive motor is also mounted inside, out of the element. To the right of the image you can just make out a plastic food container. This protects the electronics from the elements. Inside you’ll find an H-bridge to drive the motor, a real-time-clock to make sure the schedule is well-timed, and an Arduino. There are a couple of reed switches which let the microcontroller sense the position of the door.

After the break you can see a demonstration video, as well as a slide show with build details. The motor is pretty quiet and, although it spooks the chicken in the demo just a bit, we’d be they’ll be used to it in no time.

Automated Chicken Coop Door Is Solar-powered

November 27, 2010 by 12 Comments

[Fileark] has been busy with the hacks lately. This time around he’s built a solar-powered chicken coop door that opens in the morning, and closes at night. A single motor slides the door open and closed using a loop of spring-loaded string. There are limiting switches on either side of the door jamb to ensure proper positioning. The grey box seen above houses the hardware; a regulator for the solar panels perched atop the roof line, a battery from a broken UPS, and the driver board itself. An AVR chip running the Arduino bootloader monitors a phototransistor to detect sunup and sundown, driving the door motor appropriately using a pair of relays.

Check out the demonstration and hardware overview after the break. [Fileark] was inspired to build his after seeing the alarm-clock coop door. We don’t know if he got a chance to look at the vertical coop door, but we think his less mechanically-complicated solution is just as elegant.

Automated Chicken Coop Door

Here’s a pretty cool implementation of an automated door, built for a chicken coop. The electronics are fairly standard, an Arduino and a used cordless drill. The end product will be not only wireless, but automated based off of ambient light as well.  We also found the locking mechanism quite elegant. He also supplied a link to another automated chicken coop door which has a decent writeup with schematics and such. Next, he’ll have to automate their feeding as well.
