    Automation with Arduino

    I'll assume you are already using a controller of some type and know how to connect/control other stuff (relays/etc) from it. To be transparent I am a complete hack. See those capacitors in that board above.. No idea if they were necessary or even helpful but everywhere I looked people said to...

    Electric/Automated Brewery Dilemma

    I'm going to go out on a limb and say yes. Mine stops short of transferring to the fermenter but leaves the cooled wort in the BK. Pick something small (but meaningful to you) and get started. You'll likely see other barriers fall along the way. I started with arduino just wanting to...

    Automation with Arduino

    Cleaning is basically: 2x cycles of fill/circulate/purge a 3rd cycle with some PBW (I actually use Oxi-clean free) then a 4th cycle to flush out the Oxi-clean (and 5th if needed). On the 3rd cycle I heat the system up a bit and get a clean cloth in the BK to break away the stubborn stuff and...

    Automation with Arduino

    Welp.. It worked almost as intended on its first brew last weekend. It was hands off until the hot break when I manually controlled the heater duty cycle to avoid a boil over. After I get a few brews under my belt I should have enough data collected to automate the heat coil duty cycle during...

    Automated Hop Addition

    Sorry for the delay. Life happened and I finally got to brew with this system last weekend for the first time. Unfortunately... The hops did NOT drop when this thing rotated. I had to manually dump them in (notice the missing tube I had to amputate :smh:). The servo actuated as designed but the...

    Wooden 3 tier, single 4x4 post for support?

    Nice whiteboard! Def going to outfit my stand with wheels like yours. That is a nice touch.

    Automated Hop Addition

    Servo is either a MG996R or MG946R... Those are the two kinds i keep on hand but I don't remember which one I used. I believe this is using a PWM signal. Admittedly I am just using a library from the webs so my contribution to SW was minimal. The tubes I used did come with caps. I guess I...

    https://www.youtube.com/watch?v=st8dmIBfVbo&feature= _ Also posted this in a new thread to make it easier to find. I couldn't find much on automated boil additions on the webs let alone HBT.. https://www.homebrewtalk.com/showthread.php?p=8102119#post8102119 _

    Automated Hop Addition

    When searching I didn't see a lot of posts on automating boil additions so I decided to post this apart from my main project thread to make it easier to find. https://www.youtube.com/watch?v=st8dmIBfVbo&feature= This is a small part of a larger project to fully automate brew day which can be...

    Software for automated electric brewery

    Check out the automated section of this forum. I am not using this software but I have seen several posts from people who have and could likely answer your questions. https://www.homebrewtalk.com/forumdisplay.php?f=235

    Wooden 3 tier, single 4x4 post for support?

    In your initial statement it sounds like you want to use wood for cost. If that is the case, consider something like this. Pots on this setup are 8gal each. Raise it up a foot and you could have the boil kettle on the ground. Bill of materials for stand alone --> All can be had from woMenards...

    Automation with Arduino

    Same basic concept as Hops-Boss (check youtube). I will use a servo at the center of rotation instead of a stepper/DC motor at the perimeter. Mine will be mounted to the brew stand instead of the kettle. Anticipated BOM Scraps of ABS sheet: $5? ABS box to keep steam from servo: $5 Servo...

    Automation with Arduino

    More details on the electrical hardware. What is not obvious in the pictures is the purple PCB is a shield which sits on top of an Arduino Mega. The purple PCB just gives me a one-stop-shop to hook up everything that requires logic to operate. You might notice the SSVR is NOT connected in the...

    Automation with Arduino

    This is pretty close to capturing the big ticket items and incidentals. Total cost came in around $1,750. After I add in parts for automated boil additions we could probably round up to $1,800. Note that $360 was just for stainless fittings. Of that ~$111 was for camlock fittings to make...

    Two vessel HERMS system idea

    Pictured below is my system with 6 valves, 2 pumps, 2 Heat exchangers, 1 heating element. I will eventually add a 7th valve on the water source for redundancy since mine will be connected to the house water supply. https://www.homebrewtalk.com/showthread.php?t=633943 My steps are similar...

    Automation with Arduino

    I was going down a more traditional path until I received two heat exchangers for the price of one (cosmetic shipping damage to first). I couldn't let it go to waste so I found a way to use both.

    Automation with Arduino

    Okay... So I was trying to add a post with a 3d PDF and realized I could post a *.mov file. Attached is a short vid of me with the user interface. Quick press of the button = Select Hold button for 350 milliseconds = Exit/Return

    Automation with Arduino

    Yes. See attached Pictures. I don't know of a great way to add a video to this thread so you're just going to have to take my word that the rotary encoder is a fairly efficient way to interact with the controller. Top LCD Prior to brewing, primarily used to help me understand where I am in...

    Automation with Arduino

    Step 7: Boil sequence. Boil additions will be automated and dumped into hop spider (or equivalent). Toying with the idea of periodically pumping wort into hop spider to increase hop utilization.. Step 8: Cool the Wort after boil with tap water. *If I add a 3rd vessel down the road...
