I am considering a fairly big project and I think using a Raspberry Pi would be the way to go. I need to tackle several different problems with it though and figured I'd ask here to see how much poo poo I am getting myself into before really throwing myself into this. I'd prefer to build / assemble things on my own vs buying a pre-packaged solution, if that matters. I also have set up and run a PiZero as a PiHole server for my house that's been working great. That's my entire experience with the Rasbpi platform. I have a chicken coop that I just built: https://forums.somethingawful.com/showthread.php?threadid=3417601&pagenumber=302#post504436105 It's within wifi range of the house but inconvenient to run power to directly so 1st thing would be: 1. Solar power / battery setup for the Raspberry Pi. Powers everything else below as well. 2. I'd like to set up a remote door opener for the coop. Nothing on a timer, just something I can fire off a command for the circuit to activate (probably will use a small motorized piston arm to move the coop side door up and down). 3. A dedicated temperature sensor that logs temps and alerts an email address if temp gets above or below a certain range. 4. Have the device also trip a circuit when the temp is below a certain level to activate a water heater to keep their water from freezing. I have an eye on some fairly low current heating stuff for this, suggestions welcome. 5. (Not mandatory, maybe for later) Have a camera in the coop that streams either time lapse images or video to the network that we can view (think baby monitor) to see if the chickens inside the coop are well. This would all be new stuff for me, if I should move this to a different thread please let me know but it seems like an achievable project and I'm in no rush with it since we can do all of these things manually quite easily and most of this won't really be useful until winter anyway.

Lockback posted:Camera is the easiest part, running solar is the hardest part especially because your low temp stuff is going to happen in the middle of the night in the winter, most likely when you have problems with your solar setup. Long extension cords are probably way way less of a hassle. Yeah I'm thinking set up 1-2 fairly large panels and a substantial deep cycle battery. If it's not enough for this application I can use it to power a watering pump for the garden or something next spring and run an extension cord to the coop if its just not good enough.

poeticoddity posted:If you're going to go to all of that effort to automate a chicken coop, consider including (and sizing your battery bank for) supplemental lighting and ventilation (for any high heat events and moisture regulation). Both are very easy to address early, but may require completely changing your battery system if you need them later and haven't sized for it in advance. Ah yeah hadn't thought about messing with ventilation (the coop itself has airholes up at the top and the windows are on lift out hinges and are removable to let the entire thing vent during warmer months. For the water I was thinking just 1g or so in a thermos inside the coop itself. So yeah not like heating 5-10g out in the elements at least.

Lockback posted:I know we're all stuck on the power delivery, but how far from the coop is the nearest outlet? This is excellent, thanks! I kinda didn't know where to start given there's so many different ways to do these. Any reason to go with something beefier than just another piZero for this?

For the record I'm not running any power to the coop other than a temporary extension cord to get the system troubleshooted and running until solar is working.

Crosspostin from the learning electronics thread. I wanted to see if anyone had guidance on best practices to make a breadboard functioning circuit into a prototype. Basically I have this motor controller and the Pi, and a separate set of jumpers not shown that connect to a 10k resistor and a temperature sensor.  The motor controller contracts / extends a 12v linear actuator to open/close a door in the chicken coop. The 5V power on the motor controller powers the Pi and I am using DS18B20 temperature sensors. I've gotten all the individual circuits / initial test scripts working and everything functions well now on a breadboard. The system is powered by a solar-charged 12V DC battery. These are all going to go inside a chicken coop and will be out of any wind / rain but will at least need to be covered and put together in a way that is sturdy / stable. They will be mounted fairly high up on a board that is mounted to the wall with a standoff inbetween so they are not directly connected to the exterior wall (hopefully will keep down external temperature extremes). My current thought is to put the Pi and motor controller into a 2-gang PVC electrical box with a solid cover on it and have wires going in-out from it via PVC conduit. What's a good way to connect all the GPIO pinned stuff to each component long-term? Should I be putting this into a different type of enclosure etc?
