Just received my Brucontrol Uniflex V2 (HUGE shoutout to @BrunDog ....I can already tell this system is going to totally rock!). I am outfitting a spike solo to be ~90% automated utilizing ~8 bidirectional 24V valves. Will post pics post-Uniflex integration :). Question for the group as I am...

Thanks so much for your thoughts. Any suggestions how best I can support the pipe/valves outlined in red (weight ~15-20lb)? The big red blob in this image will be the kettle which this valve line will connect. Was thinking i could use a stauff clamp to bolt around the leg of the stand and attach...

Adding 3x motorized valves (2x 3 way, 1x 1way) to a 1.5" TC weld (Spike solo)...are there any standard weight limits for TC welds? Not sure if this is too heavy

Nice job- very cool! Out of curiosity- do you have a bleed valve on your pump? I have the same pump and building with the same head orientation. Debating whether to add a bleed valve.

For extending the wires of your motorized valves (hot side), what is the easiest/fastest (and water tight) way of doing this? Thinking thermostat cable w/ heat shrink tubing to cover the soldered connection point. Previously built XLR cables (w/ nylon sheaths) for cold side automation...

Not sure on excess tubing. I tried to replicate Blichmann's as closely as possible. If I remember correctly I thought there was a reason for 3 ft beer line on the beer out end (after passing through the "T". One thing I would do is to build this with a checkvalve at the gas port. I had a mess...

I’m building a fully automated fermentation controller (Brucontrol) and want to ensure pressure (positive and negative) can be mechanically prevented given computer programming will drive this process. Mechanically, I’m making a safety assumption there could be faulty sensors, gas leaks, bad...

Good thread...one main question . I’m building a fully automated Arduino driven fermentation controller and want to ensure pressure (positive and negative) can be mechanically prevented given computer programming will drive this process. Mechanically, I’m making a safety assumption there could...

Great build! Plastic or metal raceways? Debating between the two

Great build! Any issues with EMI? Building my panel right now and not sure what to isolate vs not. See you have the raceways built in...are your’s metal or plastic and did they come with the panel enclosure?

Thanks for the great thoughts here. Would I be better off with a IRLML6344? Looking at the specs it appears I can use a 0-3.3V at gate. Thoughts?

2. How would I re-wire this per your comment that 3.3v is not going to be enough to operate the MOSFET? I didn't say 3.3V is not enough to operate this MOSFET. It just will not be open fully just partially. May be it would be enough to operate your coil or may be not. If you have your coil...

I guess that makes sense...my cost is much higher as I am starting this build from 0 meaning no power supplies, enclosures, wiring, etc. etc.

Thanks Peter! Let me update this per @brumateur1 suggestions and send over. Should be quite close.

@brumateur1 Thanks for the thoughts here. This is super helpful. To summarize, seems like there are 2 protections we are taking: 1. Prevent ESP from overcorrect BACK into ESP through pin 23 2. Prevent EMI by adding in a pull down resistor to ensure MOSFET stays closed when pin is not configured...
