NOTE: With the economy as it is, the HBD is struggling to 
meet its meager operating expenses of approximately $3500
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.






Financial Projection as of 03 December 2012
***      Condition:  Cautiously Optimistic      ***
501(c)3 status rescinded. Refiled 1023 for retroactive 
status 25 June 2012. Did not hear back within 90 days; 
therefor, must assume that there are issues and our case 
must be assigned to an agent. IRS is currently assigning 
applications received in February 2012. Ours was received
in June. We will not have our status reinstated for the 
2012 tax year. To current financials, HBD is officially 
bankrupt in May. Due to recent political developments, 
HBD.org will likely have to be dissolved per the bylaws 
once funding runs out.

Subject: Great Club Malt Experiment

Greetings all! With the lower load of traffic on HBD lately, I have a 
good topic to get some discussion going. Our club is planning our year 
and I would like to organize a "Great Club Malt Experiment". Basically 
we would like to mash and ferment a series of specialty malts with a 
consistent batch of base malt.  We plan to keep as many variables as 
possible constant with the ultimate goal of tasting all the different 
beers at a club meeting andeducate ourselves on the tastes of the 
various specialty malts.

Our first stab at a plan includes the following malts: Marris Otter, Six 
Row, Two Row, Pilsner, Wheat, Rye, Munich, Vienna, Aromatic, Brown, 
Crystal 40, 80, & 120, Biscuit, Chocolate, Smoked, & Special B.  We are 
thinking about each club member doing 1 malt and we would all use a slug 
of the same yeast slurry from our sponsorBrew Pub.For the base malts in 
the list, we would only use that malt.

I would love to hear any comments, suggestions, links to experiments 
already run, etc.  Private replies are fine but if you don't mind, 
please respond back to the HBD and lets get some traffic goingand keep 
Pat and the boys working!

Thanks!

Subject: Homebrew Gadget: Help Needed to Construct a Continuous Liquid Level Sensor for Boil Kettle and HLT Volume Measurements

I would like to move beyond the sight glass measurement of liquid level that
I currently use in my brewery and am looking into a capacitance-based
sensor.  I have constructed a prototype sensor probe and connected it to a
simple circuit.  The readings are steady under constant conditions and
removing an ounce from the vessel causes a change in the frequency reading.
Very promising!

 

I'd like to take the next step and build a better measurement circuit, but
find myself in need of help.  While this request might be better suited to
an electronics forum, I thought I'd pop it up on the HBD to see if there was
anyone here-perhaps an electronics or control engineer-who might be willing
to provide some advice.  

 

If you would be willing to help, or if you are interested in liquid level
measurement for your own setup, please send me an email and I'll send more
information.

 

Happy Brewing!

 

Kevin
