For automation on the flow rates we are looking to control. Look into getting a brush-less permanent magnet DC pump. You can control flow rate by controlling the voltage at the pump which is easily done with PWM and a smoothing circuit. As was suggested above, a throttling valve is your other...

Don't need a code as I've already bought my stuff... But I just wanted to give this thread a bump after a wonderful customer service experience. Put together my panel using this kit and had a relay fuse closed and a 25A breaker that trips at 22A when it warms up. The guys at ebrewsupply...

yup, in this case the patent system is working as intended. The patent owned by Monsanto was specific and related to the introduction of a specific gene at a specific location resulting in the proper resistance in the plant. I can't claim I know enough about the patents, but where I hope this...

I love hijacking threads. I am of the opinion that the costs of phenotypeing is a function of the cost of computing and genotyping both of which are declining. Rapid and inexpensive sequencing yields large databases for faster more efficient computers to sort through. And yeah, she be...

Well my industry (semiconductors) and most tech industries suffer from patents tend to be used more as a cudgel to be wielded against others who happen to have a similar idea to some overly generalized concept that happened to be grated a patent. They restrict innovation by creating many cases...

hehe, used wheat as an example, but a poor one as there isn't any currently approved for use. I wanted to make sure I had everything straight as I hate feeling ignorant on subjects. I wandered through a bit of research to become hopefully better informed. My current understanding of how GMO...

Meh, the only real issues with GMO is how the companies that hold the patents use their monopoly and how it encourages less diversity in the crop. Monsanto produces a single strain of wheat which it sells to farmers everywhere and then farmers plant only that strain. That lack of diversity...

Had my boil element all hooked up and chucked together a quick Processing/Arduino sketch combo to play around with PID settings. Verified ground was good, verified resistance across element was good, verified power at outlet on panel was good and not shorted anywhere.... Second power hit the...

looks like that's a bleach based cleaner so the stuff you see on the bottom is probably salts created by having a warm bleach solution. When bleach is heated it self oxidizes and produces salts which precipitate out of solution. Also when heated it can put out Chlorine gas which is nasty. But...

What chemical did you use for sanitation?

someone might finish typing this out before i get it in... but it's just a simple ratio. Specific gravity is (density fluid)/(density water). The higher specific gravity of wort than water is due to dissolved sugars increasing mass but not affecting volume. specific gravity may be unit-less...

The cold and streptococcus swept through the family this weekend, but I preserved. Got my nasty large gauge wire shoved through conduit. I did a summer working as an apprentice electrician, but I must have been in way better shape then. Running wire sucks. Got the spa panel hung and wired...

And got some dedicated hot and cold water lines T'd into the garage for brewing.

Got my boil kettle all setup. Did a quick test with a chugger pump and it yielded an okay whirlpool. Not terribly impressed though

Right now, plan is to hold a back plate with screws tapped through the front of the panel. Slide the tablet in and snug it up with some nuts on the back of the plate. I didn't want it to be permanent as I do want to level up towards more industrial quality components as time/skill/money allow...
