petfeedd users, I am proud to announce the beta release of petfeedd 1.0.1. This release has no major changes in it and is solely about addressing security issues in many of the underlying libraries used by petfeedd. To install it or upgrade from previous versions, you can simply run: docker pull peckrob/petfeedd:latest

After five beta releases and months of testing, I am happy to announce petfeedd Version 1.0 is now available. All changes from the beta branch have been merged in and the release is now available on Docker Hub. To install it or upgrade from Version 0.2, you can simply run: docker pull peckrob/petfeedd:latest And restart. It should perform all the upgrades needed for version 1.0.

petfeedd users, I am proud to announce the beta release of petfeedd 1.0. It’s been almost three years since the last release of petfeedd (version 0.2.2), and Version 1.0 marks a new start for this project. I have been running the beta release on my feeders for the last week and I believe I have smashed all the major bugs.

I’ve had several people write me recently and ask about how to use petfeedd with multiple servos. It’s actually now my most common feature request, so I will definitely be sure that that is added in the rewrite that I am currently working on. In the meantime, you can run multiple instances of petfeedd using Docker, each pointed to a different servo. I would be sure to offset each servo by a few seconds to be sure you don’t have any voltage drop issues with the Raspberry Pi.

petfeedd, the software for pet feeders, has a new release. 0.2.2 is a maintenance release that add support for new Raspberry Pi Hardware. There are no breaking changes in this release.

petfeedd, the daemon I wrote for my Raspberry Pi-powered cat feeders has been updated to fix a number of bugs people were seeing attempting to install it since I originally wrote it in 2017. Perhaps the biggest change is Docker support! That’s right, if you just want to run petfeedd, now you can do it in just three commands! No more installing various libraries and things (but that approach still works as well.)

In my last post about building the pet feeders, I alluded to one of the limitations of the Raspberry Pi has: it lacks a real time clock. This is an understandable omission. They take up extra space and cost, are not needed for a lot of applications and can be pretty easily added if they are. One of the limitations I found is that, if there is a power outage that lasts a significant amount of time - long enough for the UPS batteries that keep the wireless up go dead, for instance - that the Raspberry Pi’s may “lose” track of time if they can’t reconnect to wifi and, thus, sync up by NTP.

As with many of my projects, it started with something that made me angry. In this case, it was this: The Petmate Le Bistro Pet Feeder. Okay, let’s back up a little bit. Back to about 8 or so years ago. We had a cat at the time, Pumpkin, who as objectively not a good cat. She was foul tempered on the best of days and very difficult to love. But she was my wife and I’s first pet, so we did love her all the same. She had a habit of wanting food precisely on time. And if it was late, she would raise all manner of noise until she was fed. Often this came at some ungodly early time in the morning. So I bought a Petmate Le Bistro Pet Feeder.
