NOTE: With the economy as it is, the HBD is struggling to
meet its meager operating expenses of approximately $3400
per year. If less than half of those currently directly
subscribed to the HBD sent in a mere $5.00, the HBD would
be able to easily meet its annual expenses, with room to
spare for next year. Please consider it.

Subject: Belgium Trip
Hi All,
Need to have some kid free time? Have somebeer bullets this summer?
A club member (Jim) Hegedus and I are going to Brussels July 27-Aug 3
and plan day trips to Trappist breweries and others along
the way. Ticket prices are going down?!! $830+ The hotel is nice, and
the more we can put in the car the less driving we have to do...
Interested??? If we get enough people we can hire a driver...
We are staying at a four star hotel, which
runs about $118 a night. This is a REALLY nice hotel. Much better
than any of the places we stayed at during the Germany/Czech trip
I organized in 2000. If you want to find your own hovel we can meet
up each morning and take off then...
$800 to get there
$700 to stay there
$500 to eat and drink across Belgium
$2 Grand and change for the trip of a lifetime!!!!!!!!
Anyone interested in joining us can contact me at
thepfhb at comcast dot net
Any belgian hbd'ers out there PLEASE speak up I could use your
help in getting this all arranged.
>>>Steve A--Wow awesome post as usual. Have you been to
the Dreher Brewery and museum in Budapest? Jim will
also be going there...

Subject: Cheap and Easy Bubble Logger
Airlock bubbles are a fun and potentially useful way to
look at fermentation, and various automatic bubble-logging
systems have been devised (see HBD archives, various web
sources). For those of us familiar with MATLAB, here's an
idea for *extremely* cheap and easy bubble logging:
1. Download FreeMAT (an open source alternative to
MATLAB--or if you have MATLAB already then use that)
2. Tape a $5 PC mini-microphone to your airlock (basically
the method Fredrik reported on HBD in the past)
3. Use wavrecord() in MATLAB/FreeMAT to capture data
With the data in FreeMAT/MATLAB you can then process and play
with it however you want. Maybe write a script to identify
"bubble events" or else take a different approach based on
connecting a given amount of RMS to each bubble. I haven't
tried this yet but I'll report back when I have (if nobody
beats me to it).
Matt
