It is for a 3-way valve where one position is to hand off the freshly boiled and cooled wort to the fermentation system, which does not yet exist. At the time, I had a hose looped into a bucket. Unfortunately, it wasn't a 20-gallon bucket.

Yesterday, I had a controller reset that opened a valve that drained a kettle onto my garage floor while I was eating breakfast. I was lucky it was just water, and that my garage floor has a nice slope towards the door. It was a single towel cleanup.

"Coil" is probably the wrong term, but I use it out of habit. The SSRs I used are 3-32VDC control. At 5v, they draw a measured 10mA. I'm also using a 12v power supply for the Mega. In comparing notes with @BrunDog, the only substantial difference between what he's running and my setup is that...

That's what I'm shooting for. I'm really fussy about leaks, so I'm hoping that between having fixed (but easily removed) plumbing and a solid CIP regimen means I don't make a mess right out of the box.

That's another alternative that I'll think about. I still want to get a few brews done to see if something would be better if moved elsewhere. If I lucked into a workable layout, it won't be hard to do something more permanent. I do like the rigidity the plywood offers to the structure. It...

How do you use the Mega to emulate PID control of an SSR without using power from the Mega to drive the coil on the SSR? I put an ammeter across mine, and it's drawing about 10mA.

@Die_Beerery, I've been testing and commissioning my new system, and I ran into some trouble with the Mega resetting. It seems that there just isn't enough current available with the way I had it set up. I was running three 4-relay boards, two SSRs, two proportional valves, three RTD amps on...

It's Home Depot plywood. When I ran a screw into it to mount a pump, I found a huge void. Version 2 might be a ¼" aluminum plate. It might also wind up being a custom stainless steel stand without a skirt board, instead of a wire rack. I had 30 gallons on it today with no complaint, but I...

Not using a RIMS tube, but I understand your point to be: Let BS suggest a strike temp, mash in, let everything settle for a bit, start recirculating, and pay attention to the MLT temp, not the HLT temp. Here's a pic of the rig. First brew on it next weekend.

Not using an insulated tun as I recirculate through the HERMS coil. Just a regular 30-gallon kettle.

I'm just about to christen my new ½-bbl 3-kettle HERMS system, and I'm looking to create a profile in BeerSmith. I'm using the 0.12 stainless steel figure for mash tun specific heat, but I don't know if that is offset by the recirculation or not. Also, does anybody else use the Ss Brewtech...

@ClaudiusB, I was beginning to think that Texans were no longer on the top of the "biggest & most" pile. You have alleviated my concerns.

I started water testing tonight. There is a little bug to work out with the proportional control valves, but a fix is on the way. It's not straightforward to control a valve that is looking for a 0-5v analog control signal with a digital PWM output from an Arduino Mega. I ran a watertight...

Having the terminals bear directly on the wires is safe and well within "best practices," as long as the screw for the terminal does not bear directly on the conductors. In the case of ABB, Phoenix, Schnieder, etc., the screws tighten a ridged plate that bears on the wires. You do have to be...

If you build a panel around the power supply as drawn by @doug293cz, just bear in mind that with the abandoned neutral, you will need to source everything you use as compatible with 240VAC. A regular 120v Chugger pump, for example, will not work.

If your walls are open right now, it will never be cheaper to pull the cable for a dedicated outlet. You can always choose to not use it, but if it turns out that a full electric system is what you really wanted, it will be expensive to retrofit.

Once a month is exactly the target I'm looking for. I figure I can keep two taps going in a steady rotation (maybe three?), so there is always something different to change things up. I figure I'll have some months where I work to give away growler fills, and some months where I have to boot...

It's a cherry I can hardly wait to bust!

Here's a link to one paper. Not sure if it's the same one @BrunDog is referring to or not: https://open.library.ubc.ca/media/download/pdf/24/1.0074423/1

Here's one source: https://www.alphanovatech.com/en/naturalcone.html that doesn't favor top or side, as long as the air can move across the fins. Still, it recognizes that airflow plays a part.
