@adman, within 7" from the source of power is the rule of thumb in my industry. In your case, the source of power for the light gauge wire for the pilot light is at the SSR terminal. The objective of overcurrent protection (fuses & breakers) is to protect the wire. @augiedoggy and @adman, Damn...

None that I can think of. That said, why do you have the contactors there in the first place? Also, please make sure that the 1A fuses from the SSRs to the user console element pilot lights are installed close to the SSRs.

Tonight's update is about an extraordinary opportunity I had today, to sit at the foot of the throne at Casa @BrunDog for an early morning brew. I'm going to cover some of the notes I took. To start with, some hardware context is probably important: @BrunDog's rig is different than mine, in...

I have a question and an observation. My question is for the OP... @Metzen, how have you dealt with condensation forming on the outside of your glycol reservoir? I may be able to help answer @jturman35 about garages. I'm in South Florida, my garage door faces South, and my chiller is about 3'...

Awesome job! Fun when you fire it up for the first time, isn't it? Also, it looks like you've got a busy, but well-organized brewery. Would you mind sharing a link to the flowmeters you are using? If you haven't, are you going to incorporate BC into your fermentation and dispensing?

I built a 54w x 33d x 30h ferm chamber, and built a heat exchanger out of a transmission cooler I bought from Amazon and two 4" muffin fans. I submerged a backyard fountain pump in the reservoir that pumps the solution through the hx. I have some pics at this thread for reference.

With mine, I found that with a 50/50 propylene glycol mix, I could get the solution down to about 23℉ or so before it got difficult to pump. I also learned that propylene glycol is hygroscopic. Rather than evaporating, my reservoir filled itself up. It also diluted the solution, gradually...

BruControl. It's an automation front end for Arduino-based microcontrollers.

Your sacrificial virgin count seems a little low for this quarter.

I recently upped my brew game from a 5-gallon batch size rig featuring a Rubbermaid cooler mash tun and a cut-open ½-bbl keg boil kettle that sat on a turkey fryer burner. I've spent the best part of a year building it, but I now have an automated ½-bbl electric 3-kettle HERMS rig. I used Ss...

Another update: I brewed a lager (my first one!) a week ago today, christening the new fermentation chamber and newly MOV-equipped controller. I'm really happy with the 4-hour graphs I'm getting back from BruControl. It's easy for me to visualize what's been going on inside the box without...

Ahhh...Danica. [earlier pic was supposed to be a humorous reference to GoDaddy, but it wasn't.]

We're all just happy the dark days are behind us.

@TexasWine I run BC on an old MacBook Pro, with a Parallels Win 10 virtual machine. When I first fired it up, it took a little back-and-forth with @BrunDog to sort out a COM port issue, but it's working like a champ now. If I can get it to run on a Mac, it won't take long to get you rolling on...

You've done your homework. Should be a piece of cake.

Awesome sauce. Thanks for the info. I'm using BC, so no direct Arduino coding for me, thank you very much. I've heard rumors that the next iteration of BC will have progressive calibration slopes, which should take care of the Excel requirement pretty handily. My rig has flat-bottomed...

Has anybody here got a source for a relatively inexpensive 5V ½" NPT flow meter with a pulse output that is rated for at least 100℃, and is beer safe? I've seen loads of choices with 80℃ ratings, but I'd like to be able to measure out of the boil kettle. Hi-temp units that I've found run into...
