A coworker of mine just gave me 2 pin lock cornies, but i am setup for ball lock. I have not done anything to them and they probably need to be rebuilt with new orings, etc. The usual scuff marks and stickers, but no major dents. Looking to trade for 2 ball locks in similar condition. I am in...

And here I thought I was being clever... Thanks for the heads up, I didn't know what to search for, but I will check out the other builds! Sent from my iPad using Home Brew

Just thinking about my next build. Instead of an external rims tube, could I have an element below a false bottom and control temps that way? If so, I could do a single vessel biab type system then use the same element for the boils. Any thoughts? Sent from my iPad using Home Brew

I have some basic coding done, but still needs a lot of work. I will try to post it this week. I like the idea of collaborating because we should be able to put together something (hopefully) robust, and a lot faster than I could do on my own. FYI, I am using Hall effect flowmeters from adafruit...

I got them from adafruit. I have three of the plastic ones and one of the brass ones. Sent from my iPad using Home Brew

Yes, once I have it cleaned up and better documented I plan on opensourcing it through GitHub so that (hopefully) people will enhance and build on it. I will also start a thread on homebrewtalk to document my system and how I have it all connected to the BBB so hopefully others can leverage the...

http://m.ebay.com/itm/251457815300?nav=SEARCH These are the 12v pumps I use, perfect for transfers and recirc. I have three, for the hlt, the mlt, and my rims tube. I still use a 120v march 809 pump for my bk to whirlpool and chill. It has a flowmeter attached, so I can track transfer volumes...

Once I get the code a little cleaned up and further along I will be open sourcing it on github. I will be starting a new thread here for the project once I reach that point. Sent from my iPad using Home Brew

I ported the arduino pid library to javascript as a node.js module. In the near future I plan to do the same with the autotune library. I actually am using the pid with my (12vdc) pumps to be able to set a desired flow rate and let the pid adjust the pump output to maintain it. Sent from my...

I am using the beaglebone black for almost exactly what you are doing. I will be controlling my pumps and rims tube, and later plan to control fermentation temps via heat jackets. The bonescript library makes it pretty easy to setup via node.js. I am using an express.js front end to allow me to...

Yep, I have them on my hlt, MLT, and my rims tube. I still use a march 809 on my bk for whirl pooling and chill, but these guys are great for sparging, recirculating, and transfers. Sent from my iPhone using Home Brew

I have a BBB and m using it for a lot. It controls my rims tube via a pid, as well as controlling my pumps (3 12v and 1 120v), and I can control the flowrate of the 12v pumps with pwm. Each of the pumps has a flowmeter so I can see flowrates and track transfer volumes. I also have four DS18B20...

I am currently working on a beaglebone black to control my system. Eventually, I plant to add automation functionality, but that is down the line. My setup uses 12v pumps on the hlt, mlt, and rims tube, and a march 120v on the bk for whirlpool and chilling. I have four DS18B20 temp probes which...

I am currently in the process of building my system out. I am using 12v pumps coupled with Hall effect style flowmeters. As stated above, they have to be calibrated as they are non-linear, but my plan is to use a pid algorithm (I ported the arduino pid library to javascript as I am controlling...

You can use bonescript to control it. Basically, find a pwm pin (I would start with P9_14, it is already correctly configured by default) and use the analogWrite() method which takes an argument from 0 to 1. So if you pass .5 it will run at half speed. On the hardware side, all it is is a...

I might consider adding a little pale chocolate malt, and maybe a little special b (a few oz). But then again, it is not bad to keep it simple. The more complex the malt bill, the more the pecans have to compete with.

I started at about 5psi for the first few days, then let it build up to 10psi, then stepped up to 25psi after about 5 days. To grab a sample, all I do is hook up a picnic tap to the out port of the cornie. The dip tubes are cut about 3/4" so I don't get too much trub.

Right now i am doing 5 gallon batches of everyday/session beers, and 10 gallons of higher gravity beers. The longer they need to age, the more I brew at once. I don't drink it all. I enjoy sharing the beer with others just as much as I enjoy drinking it myself. Especially when people come to...

So after shaking it a few times to get the yeast back into suspension, I am still only at 1.041 tonight. So, improved, but not a whole lot of activity. What do you think, give it more time or get another smack pack?
