Thanks for the link, I've been looking all over for reasonably priced automatic valves.

I've found great sources especially in this two systems

Black Heart Brewery
Black Dog Brewery

And you can find useful also this

I'm going with LP gas burners, so I don't have to deal with the heater electric part.

cheers

[off topic] Just seen your keezer: AWESOME!!!

Little step today, bought the enclosure for the bubbler volume sensors and aquarium pumps. Cheap, but everything seems to fit properly inside.



Now, for the bubbler system, I have just to wire the sensors to the bt board connectors and to cut the tube in the right lenght for reaching the kettles from the enclosure. This is to be done when the build is almost at the final steps.

Another day has almost gone with a further small step done.

Made the holes for the xlr panel mount connectors in the enclosure, in which the bt boards, sub-boards, power supply and airport express (giving wifi to bt). Tomorrow I'd like to place the switches as well.





Bought the hose couplings for the honeywell valves as well



These are the xlr cables waiting for the valves and the pumps



And this is what I've received today, since I'm planning to brew a wit beer as soon as I could. I've already have a lot of pilsner grain waiting to join my brewing day!

Nice system so far! I think the mash tun is my favorite part.

A suggestion for you though. Remove the ball valves you have on the input side of your pumps. They are designed to be restricted on the output. You can actually ruin them if you restrict on them input side.

Thanks Carter,

you are right, actually I have the ball valves on the input size of the pumps since I've not already bought F-F 1/2" couplings, using the valve instead. They're always 100% open!

Although I agree with your above statement about the valves on the input side (when using manual valves), there is a major advantage with automation. You can design the program to not turn the pump unless one of the input valves are open.

Keep up the great work, goingmad! I have my BT 3.3 on the way.

And also you are right Squeeky, but I'd feel more safe to have a manual valve backup for everything that could go wrong, while brewing, with the electric system. I'm going to have manual ball valves for every output from the kettles as well. For the same reason even if with electric honeywell gas valves, also there I'll have manual gas valve as a safety backup. Never managed a system like this, quite complex for my previous experience, so I feel better with some additional "emergency exits".

As for the bretroller, the recent updates, especially with the web gui, place it a way better than before. I really can't wait to brew with it!!! Good luck with your build too!

What is the material on top of your mill hopper? I'm looking for some edge banding to protect from sharp edges like that. Nice build too.
