    BruControl: Brewery control & automation software

    I have gotten several direct responses from them recently as I’ve been building my system so they’re still active. That said their absence here after being so active in previous years is worrying. basing my build on the esp32 though gives me a bunch of options to use the hardware with other...

    BruControl: Brewery control & automation software

    Yep, passing through a Global element does work to trick it into respecting precision! That seems like a lot to go through to format a string but now that I'm actually using the scripting language I'm noticing how peculiar it is at times. Thanks for the note on names... I can see that being...

    BruControl: Brewery control & automation software

    No luck. It's the same results. You can see in the Variables tab that the Value type is formatted correctly, but once cast to a string all the sudden the full precision of the RTD probe is back. I don't see anything in the guide that actually covers how type casting works in the brucontrol...

    BruControl: Brewery control & automation software

    Im finally up to coding my brucontrol rig and I have an issue with the display command that is stumping me. I cannot figure out how to write an element value to a string with a defined precision. I've tried storing the value in a Value variable and setting precision there, but that precision...

    BruControl: Brewery control & automation software

    Well on further examination I may have misdiagnosed my issue. I am still having issues but I can reliably recreate them with a straight digital out (no dual throw, no one-shot) on serial. In this configuration on any pin -- and only in this configuration, Brucontrol complains about a checksum...

    BruControl: Brewery control & automation software

    Following up on a discussion a few pages back on which ESP32 pins can be used to drive SSRs (and some other learnings on ESP32 with Brucontrol). Confirmed that I can use any pin that supports digital out as either a straight digital out or duty cycle. I am wiring 2 SSRs to pins 32&33 without...

    BruControl: Brewery control & automation software

    Yep. Reading the wiring map in more detail I notice a note that PWM is fixed at 1000Hz. That's way too fast for a SSR. You could drive a SSR with PWM at say 1Hz, but since Brucontrol has fixed the frequency to 1000Hz, PWM is off the table. I believe though the way to interpret this is you...

    BruControl: Brewery control & automation software

    I have no idea where that requirement about pwm capable pins on esp32 comes from. The esp32 is a nice platform because of how flexible it is with configuring the pins as digital, analog, or pwm and in other projects I’ve done I’ve never seen such a limitation. I am about to wire up several...

    Yet another DYI Plato scale

    I’m using a few HX711s with a esp32 and have never had any issues with them interfacing. My issues are all aligned with drift over time. I’m using them to measure kettle volume, which works fine but after an hour or so I find my tare reading has drifted by enough to make me annoyed. I also...

    Is there a way to "automate/control/monitor" a Tilt and an Inkbird WiFi Temp Controller for Fermentation?

    I did my glycol fern controller by starting with the tiltpi node red flows and adding to them. I already had some 1wire gpio/SSRs and temp sensors and discovered you can interface 1wire with the rpi gpio pins just with the help of a few resistors. I use node red dashboard on a touchscreen...

    Diagnosing my new-to-me minifridge kegerator

    I used to have a ‘high efficiency’ room ac unit that showed similar behavior. It had a digital control board that seemed to artificially limit how long the compressor was allowed to stay on — to the point it couldn’t cool a room effectively. Fixing it required bypassing the control board and...

    Blowoff W/O Sanitizer

    Same. I’ve only ever used water in blow off jars. Never had and issue. The bugs we care about cannot climb up the blowoff tube.

    calling out to the wood workers...

    That looks like a roll on epoxy finish? Like garage floor coating? That’s not a bad idea. I’d go with that. I was referring to the bar top poured epoxy mentioned earlier in the thread where you could spend $100’s to put a crystal clear coat on plywood. That would be a waste in my mind.

    calling out to the wood workers...

    I’d just fill with wood filler, sand, and paint it once and be done with it. Pine plywood is just not worth the trouble and expensive of an epoxy coat. You’ll never sand that kind of plywood smooth enough for a really finished look - but you can get it looking prettier and the paint will help...

    90* Elbow for Blow-off tube

    3/8” is pretty small and could clog with a particularly vigorous fermentation. Elbows are prime locations to trap gunk too. That said, so long as you have reasonable headroom in your fermenter you’ll be fine. Leave a few inches and the krausen (Or enough of it) won’t make it to the tube to...

    Acquired some frozen cherries.....do I have to pit 'em before use?

    Yep. I believe that’s also the source of the “almond” flavor.

    7-14 Gallon Tank with Glycol Jacket instead of Immersion Coil?

    I used the silver bubble wrap looking stuff. — which looks similar to what you have. The insulation needs to be tight around the vessel with no air gap and use aluminum tape (like The real stuff you use on duct work that isn’t “duck tape”) To seal it completely. If there is any space, sealing...

    7-14 Gallon Tank with Glycol Jacket instead of Immersion Coil?

    Wrapping with copper tubing is effective and much cheaper than the jacketed options out there. That’s what I did with my blichman conical when I went glycol. it is key though to then wrap it well with insulation. Even if your chiller is strong enough to not need it, an uninsulated fermenter...
