Nicely Done!! I'm also investigating the BeagleBoard Black for my project.

There's quite a nice comparison of the two boards here.

Onboard flash and more IO make Beaglebone Black the more obvious choice for hardware hacking.

I want to thank all the people who have gone to the trouble to post their experiences, I learned a lot about what to do and what not to do. I'm still learning of course, but I've made it this far with my eyebrows intact. Hopefully something in here helps someone.

I chose a single tier design like the brutus. I modeled it after the brutus, the blackheart, berrywise's build and a bunch of other great designs here. I wanted the frame to be made of stainless steel so I could store it outside and not worry about rust. I don't have any pictures of me welding the frame.

Obviously the pumps and valves and whatnot aren't going to be as resilient as the frame, so I made it so that the plumbing can be detached. Here's half the pump/valve system.
Awesome build! Do you by any chance have a parts list of this build? I'm especially interested in the solenoid valves you are using for this setup.

Also, this thing going to be open source??

Thanks,
Tomek

The solenoid valves are just the gas valves in the back and the water in valve. Those are from valves4projects on ebay. The rest of the valves, the blue boxes are automatic ball valves, they don't clog like a solenoid valve might. Those I got from oscsys.com, but they're Chinese so you might be able to get them other places.

I'm not sure what I'm going to do with the software. It's not really ready to be given to people, some of it is still specific to 1 tier systems.

Wow, I am building almost the exact same thing, but I'm starting out with an AMD APU board for my OS right off the bat. I'm also planning on writing everything in .NET since it's what I know. Do you have pics of the inside of your enclosure? Also curious about what touchscreen you got? I have a 15" off of ebay that I'm going to struggle just to fit into my enclosure, was hoping for something a little smaller if the price is right.

Great work!

I didn't post it because it's ugly, but since you asked... I've got to reroute stuff to be a little neater obviously. I'd also like to get away from using a hard drive if I can help it.

I used the 10" monitor from here: http://www.chalk-elec.com/?page_id=1...&sort=priceAsc

I chose web based display because I want to be able to access it from my phone/tablet as well and not write it twice.

Good luck.

For what it's worth I think that looks pretty good. If mine ends up looking that clean I'll be happy.

I'm a little worried about space since mine is also electric so I'm going to have some SSRs and a few more plugs to fit into a 16x16x8 box. A buddy of mine is doing something pretty similar but he's just using a tablet that he'll mount on the front of the control box and connect via a usb port, thereby eliminating the internal screen, pc and HD entirely.

I like the idea of writing the UI one time like you because I also want to use my phone to remotely monitor/control, I've been trying to wrap my head around the best way to do that. Is it safe to say that all of your program logic is in javascript and your perl back end is basically just an interface to your arduino via REST? Or is your back end doing more than that?

Eventually I want to be able to basically load my ingredients into hoppers, load a beerXML/Beersmith recipe in and hit GO with no further configuration. Maybe that takes something out of the whole hobby but I would totally geek out over being able to do that. Plus I could always do a "manual mode" if I wanted to be more hands on or brew something ad-hoc without building a recipe first.

Probably what I'm most excited about, though, is the prospect of making it self-cleaning. The idea of being able to vacuum my grains out, add a scoop of PBW, hit a "Clean" button and walk away is what keeps me going through all this.

No, all the logic is in the backend, the last thing I want is to lose a recipe or state because I refreshed the page right? All of the getting and setting is done via APIs, but I'm not sure if they'd be RESTful strictly speaking.

For your friend, I'd recommend the $25 for a raspberry pi and the $10 for a wireless usb device as opposed to having to be plugged in, but I'm just some guy on the internet.

I also want to get to the point where you're just loading a BeerXML recipe and pressing go, but right now I have to at least send it to the next step each time.

Cleaning is a hassle, that's for sure. At least it's MOSTLY clean by the time I'm done.
