Great stuff -- I already had a set of Teensy 3s from the kickstarter, but was wavering in the Pi -- now I have it in hand. Have you considered isolation between the Teensy and RPI? Something like an optoisolator?

Just looked up the order I placed, I got the 2.5" 1/2" NPT thread probe for the boil kettle. I'm using Tri-Clamp sensors (in a tee) for the mash and hlt. http://www.auberins.com/index.php?main_page=product_info&products_id=261

Missed this before -- no problem sharing. My best guess puts me into this about $5k. That includes the electrical permits, running lines, sink, kettles, panel, all the stainless bits, etc, etc, etc. I didn't keep great records on the random bits and pieces, just the panel, kettles and stainless.

I drilled and tapped the holes from the bottom of the heatsink. I also matched the holes up the 4 of the existing holes in the existing hole in the enclosure. Note, that the hole in the enclosure is normally on the bottom, but it works fine on top and I didn't need to patch the hole this way...

Sure, but i'm looking for one to save the time. Edit: This isn't for me, but for educating non-brewers.

Anyone know of an image I can use for a Brewing Process poster? Looking for something that's oriented towards simple for a poster to accompany a homebrew tasting and demo at work. Most of the material I'm finding is based on professional systems.

Looking for the PCB/chips/mcu inside -- curious what they're using to read the RTD probe. No worries -- no need to break it :)

Agreed, I've been in contact with Mike and had a new pump sent. However, it had the older small impeller in the head and it still overheats. Great customer service, but not yet satisfied :(

How is this not overheating? I've had nothing but difficulty with my chugger pumps tripping the thermal saftey. I have to keep a box fan blowing on them to supplement the built in fan.

Random tip: to avoid a crystal-weizen, I was told to store my hefe's upside down. Kind of hard with corny kegs, but try keeping the yeast in suspension.

Zach over at StainlessBrewing.com is now selling stainless hop spiders. I'm having an 8" diameter made with additional depth to reach fully into my kettle. http://www.stainlessbrewing.com/Hop-Strainer-Kit_p_123.html That combined with the Brewers Hardware trub filter looks promising.

I don't suppose this is easy to do a teardown and take some snapshots of the guts? Curious what they're using, but not quite curious enough to buy one.

The DS18B20 sensors are accurate to +/- .5° C (.9° F) and have a resolution of .0625° C in 12 bit mode. I'm not sure if the accuracy is a function if time/temp/etc, or if it's just a manufacturing result (i.e. does it drift while mashing or not). The resolution won't let you get beyond 0.1125°...

Whoa. Add me to the list please :)

Debating what this is going to turn out like. Looking for the maltier end of pale ales with some clear presence of the malt bill. However, I don't want to end up with overly sweet, heavy beer. My intent is to mash relatively low around 150 and hop it to around 35 IBU most of which is from a...

Hi Will_M, The foldback element clears the side and has about 5" before it hits the other side of the pot. It shouldn't be an issue whether you use the Brewers's Hardware element adapter of the included threaded adapter. The included adapter (I'm not using).

How are you getting this to work? It only has a 1.4 gpm flow rate. I just tried hooking one up to a CIP ball and it's barely trickling out :confused:

I found these gaskets on McMaster -- Part #93185K71 .88" ID, and 1.38" OD and .093" thick. http://www.mcmaster.com/#silicone-sealing-washers/=j302gk They would work well with the 1.25" OD tubing that should have ~.9375 ID CG-703-07L 1-1/4" ± 0.040" OD, 5/32" ± 0.017" Wall

I bought the original sight glass assemblies from brewershardware -- it's this one: https://www.brewershardware.com/TC10SG.html. However, what I'm thinking is more cost effective is to take an existing TC 90 as-is ($13) + a stainless flange of the right dimensions. The tri-clamp face becomes...

I've been working on creating a new sight glass for my 20g kettle that came with TC ports for a sight glass near the top and bottom. Anyone have a metal lathe and stainless welding skills? :) After a brief lapse in my google kung-fu, I was able to find 1" Kimax heavy wall borosilicate tubing...
