Build Your Own BSD Beer Brewing Control System

I don't even usually need to worry about temperature control. I brew ales in summer (the temperature gets a bit high sometimes, giving a bit of a butterscotch taste, but it's rare I have a complete failure) and lagers in winter (they ferment at around 13C, which is a bit high, but it works OK).

    * A temperature logger kit available from from Ozitronics kits. By chance, I had seen this at Linux.conf.au in January 2004, though I already knew about it before. It connects to the system via the serial port.
    * A relay board also available from from Ozitronics kits. It connects to the parallel port and controls up to 8 relays with up to 250 VAC and 10 A, though they recommend additional wiring for currents of over 5 A. A fridge typically uses a maximum of 3A, so this is of academic interest only.

    The real fun in getting this working wasn't the hardware, which is easy enough to get. It's also not really the software, which I wrote myself, and which I'm still tweaking. The real problem were the little details and connectors and things. I spent a lot of time--see the brewing log--trying to decide how to connect things. Finally I discovered an old computer lying around without a mother board, so all the front panel connectors were hanging loose. That's exactly what I was looking for to mount the temperature sensors:

    Other issues in the mounting included the fact that the kits are designed for external mounting (and the relay board needs a 12V power supply). I wanted to mount both inside, which had the added advantage that I could use the computer power supply to power the relay board. The problem was a certain amount of external cabling:

    Click on the picture to see a medium-size version in the index
    This one shows the temperature probe assembly. There are no mounting holes on the probe board, so I had to mount it by its 9 pin serial connector. I had already connected to probe cables to a 25 pin connector. I wanted it inside the case, so I had to connect the flat cable to the serial port on the outside of the case (the grey cable going out through another cutout just below the probe board). I need to find some kind of plate that I can use to mount it inside the case.

    * Above that is the temperature probe cable, as shown before.
    * Higher and to the right, the flat band cable mentioned previously.
    * At the top are the relay power outputs (white) and the computer power cable (black). The power supply is in at an angle because it was originally designed for a smaller case, and the internal cables are too short to allow normal mounting. Some time I must buy a proper power supply.

    Temperature sensors are good and all, but what would really rule would be a networked hydrometer or refractometer inside the fermentation tank giving you gravity readings. For non-homebrewers, the hydrometer reading shows the amount of dissolved sugars in your beer. This value decreases as the beer ferments (yeast eats sugar and turns it into alcohol), thus showing you when the beer is done fermenting. Normally it's a royal pain to measure because you have to extract small amounts of beer from the tank without contaminating the contents with airborne bacteria. However, with a hydrometer floating in the tank the whole time with some kind of sensors attached to it, you would know the instant your beer is ready to drink. Not only that, but correlating the slope of the hydrometer graph (fermentation velocity) with fermentation temperature would be a homebrewers wet dream. This is because certain yeast have ideal temperatures to ferment at. Too hot and the fermentation goes too quick, generating weird tastes and esters. Too slow and the yeast falls asleep. Armed with an rrdtool graph of temp and gravity though and your beer would always be juuuusst right.

    Before you make another awful batch?

    Is your fermentation stressed?
    Is you technique just a mess?
    Put our product to the test you'll do just FINE!

      lupulize
      I made this word up, from lupulin.

      It fits. It works with theme, and even preserves the character of the origninal S&G lyrics.

      I'm done now.

    Does it come with a faux beard for those who don't have strong enough or correctly placed hair follicles? Or are you just expected to move some down from the top of your head?

    Because both BSD and Beer require a big bushy beard. The belly is self-sustaining.
