i would not consider this the crowning achievement of my obsession with homebrewing (that has been going on for a bit more than a year now, err, unblogged) but for some reason it feels like something to be mentioned. this thing now inhabits my kitchen. it is known among beer people as a
kegerator and it's just a refrigerator that houses kegs with a convenient way to serve the beer.
what's remarkable about this one in particular is that it embodies that homebrewer DIY ethos that i enjoy so much; it is nothing new or particularly original but it is heavily repurposed, hacked if you wish, and the process of making it taught me a lot.
the fridge came from the free classifieds on
craigslist, and it was naturally not meant for kegs. i had to strip the insides and move the cooling guts towards the back so i could fit two soda kegs. i added a computer fan to recirculate the cold air since the original fan wasn't working, i painted the whole thing, changed the hinges on the door and screwed a piece of thin stained plywood, just for looks. the shiny tube with the taps was given to me by friend and partner in brewing Ben, but i had to figure out a way of making two taps fit. the drip tray is an inverter aluminum cover that i scavenged from my previous job at the solar company.
i spent very little money on this thing but a lot of time. if the equation was time equals money, then this thing was really expensive, possibly more than just buying a unit off the shelf. but the gains in the learning and skill refining variables are hard to factor in. and i did it mostly for that, the learning, perhaps even the rewarding feeling of "i built it myself".
this was also an excuse to build a temperature controller. i had an
arduino lying around and i ended up expending a few days building a simple thermostat to keep the beer at somewhat proper serving temperatures (around 38 degrees fahrenheit). i will not go into extreme detail since there are really well written and googable tutorials and builds out there, not to mention the fantastic support of the arduino community at
http://arduino.cc/ but here is a picture:
i housed all the components (arduino, power supply and solid state relay) in an old VHS tape case (it closes neatly without screws). for the temperature sensor i used an
lm335a from sparkfun kindly supplied by my friend Josh.
so this thing a mishmash of brewing, plumbing, electronics, wood and metal working and tons of scavenging. it's an object that is not pure in any sense; it doesn't come from a single realm of knowledge or practice. which is probably true for most things in our world today. nonetheless i love that reminder, in a way it reinforces the way in which my obsessions and explorations come and go. dooming myself to never becoming a true expert on any single subject but leaving the door open to being curious about anything.
