I still use 'vi' (editor) on a daily basis.


Sorry, I prefer nano ;)

hahaha, I figured that would be the default. That's why I mentioned it, I'm old school. :)

Ancient, what would you connect the BrewPi to? I know you have a walk-in cold room. What else do you use for fermentation/lagering? Just thinking about the configuration and how to wire it up.

Of course it would be trivial to display the brewpi temperature in the modeline in Emacs, and org-mode would happily fetch the log data and draw you a graph ;)

That time org-mode came up on the German Brewing Forum and thought I'd died and gone to nerd heaven.

I've been eyeing the BrewPi and the BCS controllers for some time now. I have a Mac Mini that would make a good little web server for it.

See....man, someone had to chime in about emacs. :) I knew that was coming.

Side note: How about that LaTeX formatting of the Low O2 document? Kudos to techbrau, Ancient Abbey and Weizenberg on those TeX skills.

Is this model "plug and play" or does it still require programming?

How user friendly are these? Can someone with zero background in electronics, programming and coding get one of these up and running?


As a hack, but with a background doing software and hardware vendor outreach from AMD (including the first 1 Ghz processor!), it doesn't seem that hard. If you buy the prebuilt BrewPi with the Spark arduino module, then you can control it directly. Otherwise, it has a mini-menu that lets you setup everything on the little screen. I didn't find that intuitive. I also have two freezers to control, so I bought two (waiting on the sensors and power switches), so connecting these to a third device powerful enough to run a web server, should allow me to run unique fermentation profiles between the systems.

If you can carefully follow instructions, you should be fine. Hint - powering the devices from your laptop during the first configuration and before you link power out to the SSRs should prevent smoking anything. I have a fine arts degree - and I can follow the instructions easily enough - but they are a tiny bit arcane. After building the Raspberry Pi, compared to building a real computer - this is cake!

Wait, wha??? LaTeX? Shame on you Brandon!

hahaa, I was adamantly opposed to using LaTeX, wanting something we could all edit (shortsightedness on my part). Techbrau overrode and did a fantastic job.

I have only approached the BrewPi's from building a RaspPi for the web server, and building the controller from scratch (Arduino's) so don't know anything about the actual pre-built devices. I have on on order and can share more thoughts once it gets here. I have a Mac Mini that runs my home audio stuff so could use that, but eh, RPi's are cute, tiny and I can just leave it by the freezer.

I have to say, the Photon's (new BrewPi's) built in wireless is ultra convenient.

It was very well done, but I'm a troff man myself. Even used it for my wedding invitations.

Back in the day, I wrote postscript ppds for a Scitex high end rasterizer and imagesetter. LaTeX just sucks man! It tried, but seems like it was abandoned as soon as it was written. Gratz on figuring out that junk.

I am still a bit jittery about the Raspberry, but online with Time Warner which has decided that I am not competent to manage my own modem (and internal router -<insert obscene expletive>) - despite my 20 year history with them - and years running AMD's ISV gaming servers. It is against their "policy" now which changed in the past couple of years. Trying like heck to get a dynamic DNS link to the Raspberry - so I can show off the fermenters in public. That assumes I don't electrocute myself with the SSRs and break out box.

I need to write a download speed cron and shove the data up their ports!
