Running a Docker Swarm on a Raspberry Pi Cluster.

For a long time i've wanted to experiment with running a small cluster on my Raspberry Pi's, but I've always had lots of other things to do. Recently i started moving my hosted services from my NAS onto a single Raspberry Pi, and came across a few older Raspberry Pi's, and thought now is a good a time as any, so here goes. Hardware used I used the following components: [Read More]

Arduinos, Arduinos everywhere!

Introduction I've been quiet for the past months, mostly because of summer, but also because I've been busy getting (re)aquatinted with circuit design. I haven't played around with electronics in 20 years, but when I recently got my hands on an Arduino "starter kit" I just had to try it out. My go-to platform for solving home automation has been the Raspbery Pi, but RPi's have a [Read More]

New Toys

Controlling a 3D printer with a Raspberry Pi Preface I finally got around to getting a shiny new toy in the form of a 3D Printer. The specific model is a Wanhao Duplicator i3 Plus. While it may not be the best in terms of quality, it's a nice "little" printer that, after a lot of tinkering, produces some fair prints. I've had my fair share of problems [Read More]

Scheduling lights with Phillips Hue revisited

When i last looked into automating the light control, i was using IFTTT, and decided to write my own implementation because IFTTT was not very precise, and rather limited for the finegrained control i wanted. A year has passed, and there's a new version of the Phillips Hue Bridge which supports Apple HomeKit, and has a new version of the Hue API, which supports things like sunrise/sunset triggers. My [Read More]

Playing Around with Go

I've previously described my temperature monitoring solution, written in Python, and I've also described my various attempts at optimizing this solution, using NodeRED and Apache Camel, but all of these attempts have been focused on the server side, while the client has been mostly left to itself. The client runs on an old Raspberry Pi B+, with a total of 256MB RAM. The RPi also runs a surveillance camera, via [Read More]
