In the first part, I looked at the frame/enclosure for everything that we need to automate my own brewery. In this part I wanted to show which parts are on the inside based functionality. but first a picture of the enclosure while it’s being build: The enclosure contains the following things: Backside: 230V IN: Voltage in, the main power supply for all devices in the enclosure 230V OUT: Switched by the solid state relay based on the PID algorithm RJ12 Female connecter: Input for the temperature sensor that is used by the PID algorithm as input Frontside: Traffic-light interface: lights to indicate what is on.


As an avid home-brewer I own a setup that I use for testing out recipes and recreating my favorite beers with my own twist. Over the last years, my gear has improved a bit and one of my main projects is automating my own brewery. I wanted to document this, so maybe other people could use this as well. My brewing system consists of a Brew in a Bag (BIAB) system, build on a modified Weck-kettle.


Boredom is something we all experience in different ways. And the solution isn’t always that easy. You might dwell for a certain amount of time on the couch.. Or restless as you are think about thinks you might want to do, but they never seem to come up. I think a certain part boredom is necessary to facilitate ideas and other serendipitous discoveries. However there might be times, in which you would like for the pure boredom to disappear.


One of my first projects for learning programming and navigating around the digitale sphere was building a visualization based on transport data. As I use public transport for all travel I naturally wanted to know how I spend my money on it. This question has been popping in and out of my mind ever since and more recently I had some time to tinker again. This time I was wonder if I could recommend subscriptions based on historical data from a person.


As we close out 2018 and start out the new year fresh, the one thing left to do is make a video of all the 8:36pm photos that I took that year. And when uploading this video I checked out when I started, which is 2010. Thus this marks the 10th year that I’m doing this… Here’s the video: Phew, racking in around 3000 photos so far… For all I can say is that I will probably be going somewhere with this.
