[Anthony’s] chickens happily return to roost each night thanks to the spacious house he built for them. Sadly the geodesic dome never became the home of the future despite what the people were promised. But using a bit of unorthodox joinery you can create enclosures for your chickens or other animals in need of shelter.
The construction begins with 30 isosceles triangles and nine equilateral triangles which he cut from solid wood on a chop saw. To join the pieces he used metal banding and screws, which hold the edges close together but allow them to flex. This solved the problem of precision mitres at the edge of each wood piece. Once the dome was fully assembled he filled the joints with caulk and finished it with rubber roofing compound.
Our only question is: how’s he going to automate the door of the coop?
This has been circulating around the net for a bit. For those that haven’t seen it, let me just give you a quick rundown of what is happening. This guy strapped a camera to a chicken’s head. No really, that’s it. There’s some interesting science behind it though. He’s taking advantage of the Vestibulo-Ocular Reflex in the chicken. It is basically the reflex that we use to keep our eyes firmly focused on something while our head is moving. In a chicken however, they move their entire head. This means that he can strap a camera to the chicken’s head and have an instant steadicam. At least that is the theory. As you can see in the video after the break, the harder part is getting the chicken to look at what you want it to look at. We also found a conversation about it with the creator,[MrPennywhistle] in some reddit 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.

Waking up at 5:30 in the morning. [Mark Stead] didn’t like the idea either when his chickens started crying to be let out. One simple solution obviously is to eat the chickens build an automatic door opener. The mechanism starts out with an old style mechanical alarm clock, add a geared motor with some creative switch work to pull open the door, weather proof the entire thing, and done. [Mark] even modified the setup later to work with vertical doors. No MCU required for either.
Pair this with an automated feeder system, egg gathering and cooking setup, and you’re half way to having your breakfast ready for you when you wake up in the morning – around noon like the rest of us.
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.
