Not sure on excess tubing. I tried to replicate Blichmann's as closely as possible. If I remember correctly I thought there was a reason for 3 ft beer line on the beer out end (after passing through the "T". One thing I would do is to build this with a checkvalve at the gas port. I had a mess...

I’m building a fully automated fermentation controller (Brucontrol) and want to ensure pressure (positive and negative) can be mechanically prevented given computer programming will drive this process. Mechanically, I’m making a safety assumption there could be faulty sensors, gas leaks, bad...

Good thread...one main question . I’m building a fully automated Arduino driven fermentation controller and want to ensure pressure (positive and negative) can be mechanically prevented given computer programming will drive this process. Mechanically, I’m making a safety assumption there could...

Great build! Plastic or metal raceways? Debating between the two

Great build! Any issues with EMI? Building my panel right now and not sure what to isolate vs not. See you have the raceways built in...are your’s metal or plastic and did they come with the panel enclosure?

Thanks for the great thoughts here. Would I be better off with a IRLML6344? Looking at the specs it appears I can use a 0-3.3V at gate. Thoughts?

2. How would I re-wire this per your comment that 3.3v is not going to be enough to operate the MOSFET? I didn't say 3.3V is not enough to operate this MOSFET. It just will not be open fully just partially. May be it would be enough to operate your coil or may be not. If you have your coil...

I guess that makes sense...my cost is much higher as I am starting this build from 0 meaning no power supplies, enclosures, wiring, etc. etc.

Thanks Peter! Let me update this per @brumateur1 suggestions and send over. Should be quite close.

@brumateur1 Thanks for the thoughts here. This is super helpful. To summarize, seems like there are 2 protections we are taking: 1. Prevent ESP from overcorrect BACK into ESP through pin 23 2. Prevent EMI by adding in a pull down resistor to ensure MOSFET stays closed when pin is not configured...

Hi All- I have finally decided to pull the trigger on automating my brewhouse. Starting with the cold side as I am a few months out from ordering my LODO Stout kettles. Cold side seems like an easier place to shake off the rust from my (light) comp sci/electrical eng university studies...

Thanks again! Makes sense. So if I wanted to spund in keg, I could: 1. drop in hops toward end of ferm 2. let it dry hop for 2-3 days 3. Transfer via filter to keg 4. Spund beer in keg (zero oxidation) ^^During this process continue to closely watch gravity changes with respect to target...

Good points- 2 things: 1. Assuming you are NOT spending beers which have been dry hopped (no yeast left). Correct? 2. Do you have a vacuum breaker TC installed? I have thought about adding a "Y" TC extension which has both the high press (15psi) manifold PRV AND vacuum breaker for low press (I...

Thanks so much for all of this. Super helpful and appreciate the time you put into writing this. One quick follow up- what is your process for spending a beer you dry hopped? or is this not possible since you need to harvest yeast before dry hopping?

Mind sharing your estimated total cost for the fermentation control? Starting to price this out for my build and want to ensure im not way off.
