About Coffee Ad Astra

I write science-minded blog posts and applications about the extraction of coffee at, and by doing so I hope to help all the coffee geeks to improve their coffee brewing. I began this Patreon page to find out which of my future ideas interest my readers the most, and to help raise money for equipment required that will help carry the experiments and develop those ideas.

Recently I built a laptop application that turns any camera into a particle size distribution measurement device; doing this typically requires 50,000$ laboratory laser diffraction machines, and instead this app plus a bit of patience allows you to do it at home.

I'm an astrophysics researcher by day, but I also like to do science-related stuff in my free time. I decided to embark on a journey to investigate coffee extraction with a scientific approach when I realized that a lot about this subject is still poorly understood. With my astrophysics research over the years I gathered some expertise on statistics, data analysis and science popularization that are already helpful in these investigations.

There are more experiments I'd like to try and more subjects I still wish to write about. I am doing this in my free time and for fun, because I love doing it. Some of my upcoming experiments could be made way more interesting with advanced equipment - this Patreon page allows you to help me in this quest if you wish to, in a way that will hopefully benefit all my readers.

150 - reached! patrons
When I reach 150 patrons, I will make it my first priority to release the roast colorimetry app that I described here. The laptop application will be available for a small price, from which past Patreon donations will be deduced (e.g. if you donated 2$ for six months, 12$ will be deduced for you). Based on my experience with developing the grind size app, I expect this will take me between 25 and 40 hours of work, which will be spread across my free time at a rate of 3-4 hours per week.
