    2 Ventilation Questions for Indoor Electric Brewing

    I have an electric setup in my basement, and just completed my first brew today in the new space (been brewing for years, but a major flood in the basement resulted in major repairs, and therefore a brand new brewery space!) as you can see, my vent hood is diy, made from rigid insulation...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Thanks for the help! With one UNO now powered directly from the RPi, the problem seems to be resolved. Although, if RPi and UNOs are booting at the same time, not all will be recognized. A simple reboot of the RPi solves the issue, but it's a bit of an annoyance. My system includes a...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    I've switched the ids to work off of serial numbers, and have connected the 4th Arduino directly to the RPi, and finally have all 4 scripts running. This is currently with only 1 temp probe attached to each unit, and all 4 connected to a 4 channel 5v relay board. Thanks for the quick support...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    My usb hub is powered with 5v @ 1.5a. Is that not enough for 4 Arduinos?

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Hi All, I'm hoping some of you can point me in the right direction to troubleshoot. I have built a brewpi controller running on a RPI3 and 4 official arduinos (or at least I think so - ordered from Amazon Prime, and all look legit). I have installed the legacy branch of the software, and...

    Electric Brewery Quality??

    As a Canadian it's nice to see metric being used on here every once and a while. Us Canucks have no idea how much an imperial f-ton is! :)

    Vent choice conundrum

    After a 3-year hiatus, I've returned to brewing, with a focus on completing the electric brewery I started so many years ago. I have completed my control panel, picked a location in the basement, run water, drainage and power, and now I am stuck with a decision on what ventilation method would...

    Contactors-are some noisier than others?

    Hi all, Just finished wiring the 120v side of my 'Kal-esque' enclosure, and powered it up for the first time. I have 4 DPST contactors in the box (one as the main shut-off to the box, the other 3 controlling outlets for heating elements) I have powered up each contractor, and one is a lot...

    Where to put themo probe for AC unit powered fermentation chamber

    Well, for the last 24 hours I have had the thermo probe taped to the side of the fermenter, with several layers of insulation over it. Once the liquid was brought down to 50°, the AC almost never comes on. I think the key to this set up is to step the temperature down over a period of time...

    Where to put themo probe for AC unit powered fermentation chamber

    I'm using a digital thermostat controlling a SSR to power the unit on/off, so setting max times is not possible. Currently the probe is just on the end of the wires, exposed to air, so the response time is too quick, and the unit will shut of very quickly. Either the AC unit or the thermostat...

    Where to put themo probe for AC unit powered fermentation chamber

    For Christmas I have built my father a fermentation chamber powered by a 5k btu air conditioner. My question is: where is the best place to put the temperature probe? If I leave it to read the air temperature inside the chamber, the ac unit will cycle more often to get the fermenter down to...

    DIY temp controller build

    In this SSR application, is a heatsink required? I can't tell if you have used one or not. If you have, where have you placed it? Cheers, Rhino

    Help with relays to use with low voltage switches

    Hi All, It's been months, and I still haven't gotten around to purchasing switches for my electric rig conversion. It's been a challenge locating suitable 240v switches in my area, so I have decided to go with low-voltage switches. However, I need some direction on what relays I should be...
