Raising the BAR

New Bar Front ViewIt all began with a dream: a cerebral lubrication station worthy of our fine hackerspace, serving as focal point to transform the lounge from a seldom used area into PS:One’s central communal nexus. From there, a collaborative project was born. PS:One member Greg Daneau built the first incarnation of our bar. He built the bar top from an unfinished door, an open frame supported it, and it had a foot rail made of pipe. The result was impressive, even if it was but a small shadow of the glory that the bar ultimately became. Thus began an asynchronous collaborative project, with hacker inspiring hacker to hack the bar to higher pinnacles of zymurgical greatness. And it arguably served as an “altar” for the budding Beer Church.

Kegerator InteriorSeeing the bar in all its inebriating glory inspired member Ryan Pierce to build a draft system and kegerator from a donated refrigerator. It can hold up to six 5-gallon Cornelius kegs (used frequently by homebrewers) or a single 15.5-gallon beer keg. A fan forces cold air through an insulated hose carrying the beverage lines to the draft tower. The draft tower itself was built from PVC pipe, fittings, and drain flanges. An insulated return hose carries the air back to the refrigerator. This air loop keeps the beverage lines and taps cold, which reduces the tendency of beer to foam in the line. Jeremy used our TIG welder to weld a drain pipe to a stainless steel drip tray, directing any spills into a bucket.

The existence of the bar and draft system steered the focus of Beer Church towards kegging. Cornelius kegs can hold finished beer and can be used for natural carbonation (caused by additional secondary fermentation from priming sugar) or forced carbonation supplied directly from a CO2 tank.

NERP – Raspberry Pi and Beer – Monday 9-10-12

RPi beer temp controller

The next NERP (Not Exclusively Raspberry Pi) meeting will be at 7pm Monday Sept. 10th. See the NERP Meetup page for more information on location, meeting format, etc.

NERP is Not Exclusively Raspberry Pi, and this Monday’s meeting will also discuss Android and beer.

During fermentation beer must be kept at fairly precisely controlled temperatures. The required temperature varies with the stage of fermentation and other factors.

Any self-respecting beer temperature monitor would be accessible from the ‘net, and this one is no exception. Monday, Eric Stein will show Brewing Station: One’s  Raspberry Pi based temperature monitor and controller. Eric will show how the Python code and electronics work and discuss some issues around controlling temperature. Sampling the product will have to wait until Beer Church taps the keg.

The Desktop is DEAD, Long live the Desktop: The Android 4.0 miniPC

Jay will be doing a short walk-thru and talk about the user-land experience with the new Ricomagic MK802 thumb-drive-sized pocket-computer. Jay will be demoing android 4.x, Fedora, Ubuntu and/or puppy linux on the Ricomagic MK802. The Ricomagic MK802 is a $65 Cortex A8 1GHZ processor with 1GB of DDR3 Ram, 4 GB flash, wifi and a 500MH GPU (Mali 400) with HDMI video. The small computing landscape is changing fast, and the Raspberry Pi is only part of the story.
