Posted in thread: What would happen if you boiled beer? on 07-30-2015 at 08:59 PM
I want to correct a misconception that is propagated in this thread, that ethanol, having lower
boiling point than water, will evaporate off before boil.That is not true. It is true. Check up

what would happen if you boiled your finished beer? We do this all the time when we are
assaying acohol and determining true extract. The result is a foul smelling, dark soup of
precipitated protein. ...

...you cannot adequately buffer a mash to a reasonable pH using phosphate buffers ....Some more
reflection on this subject has led me to think that while the statement above is certainly true

The corrected numbers are much better but they are still off a small amount in the carbonate
(more like 11) and bicarbonate (33) based on the reported alkalinity. Interestingly enough
those would give...
Posted in thread: US 220V and European 220v on 07-30-2015 at 01:33 PM
My guess (though I've never taken one apart) is that the power lines come into a bridge
followed by DC/DC converters for whatever voltages the individual circuits need. Thus,
conceptually and if my hy...

It's significant if you are using the neutral for anything in the US spec circuit as a
significant number of the controller circuits posted here do. e.g. powering the PID or anything
else from one hot...
Posted in thread: US 220V and European 220v on 07-29-2015 at 01:43 PM
Much more importantly, US 230V is two-phase with a neutral close to ground between the two hot
phases, and EU 230V is single-phase with one hot wire and one neutral. That's not significant
at all. 220...

the MyPin is microcontroller based therefore timing is 100% likely to be based on the crystal
running the micro NOT the frequency of the ac voltage as the MyPin can probably run anything
from 85-220V ...
Posted in thread: 380V water heater element running with 220V to reduce power? on 07-29-2015 at 03:26 AM
You can put a power diode in series with the element so that it only conducts during one half
of the cycle thus producing half the usual power or about 1500 W.
Posted in thread: How to calculate how much top up water to add to reach desired gravity? on 07-29-2015 at 12:15 AM
I actually know what my final gravity should be (1.050) and what my capacity is (I can brew 9
liters), and I wanna top it up with 6 liters of water to reach a final size of 15 liters. So,
all I need t...
