DIY Brauduino System

[changchuyo]

I have been working in a Single Vessel project using the Matho's Brauduino, I have the first version ready to brew and currently I'm working on the next version, my own braumeister clone also based on Matho's controller. I modified the code to fit a 16x4 LCD and changed the language to spanish, I also have the translated code in spanish for 16x2, 16x4 and 20x4 LCD displays.


I found two cheap 43 liters chinesse pots (around US$ 15 each), and started to do all modifications.


First version


The malt basket

It was made from a dryer drum I found in a junkyard, Stailness Steel!!!!


A view of the heating elements

Standard cooper heating elements 1500Watts each (3000W). Water reachs 67°C in 22 minutes (40 liters).

Malt basket


Sight glass


Recirculation pump
I tested a universal washing machine pump (110VAC), working perfectly for 3 hours at 96°C without a single damage.


Control Box (Outdoor plastic IP65 Nema Box)


Controller shield - project board testing


Controller shield - assembled and tested


One of my 2 controllers fully assembled

And here is an advance of the next version:

Looks good mate!

Have you given it a run yet? If so how did it go without sealing the malt pipe against the base of the vessel? Ie- Was there still enough pressure from the pump outlet to recirculate/agitate the grain within the malt pipe?

Cheers

Hi Judanero, I tested the kettle and basket using a standard PID and Timer Box I built and the same SSR I'm using with the Brauduino. It works with reverse recirculation (reverse to braumeister, I mean). I succesfully brewed a delicious Red Ale few months ago.

 

[Judanero]

Ahhhh I see now, looks the goods mate!

Very impressive! Your LCD cutout on that box is immaculate!

Thanks Beer God, I made it very carefully with a Dremel standard cutting disc, then used a fine flat file to remove the barbs.

Looks great. Amazed people such as yourself have the skill and patience to put things like that together!

Very impressive mate!!!!

It looks fantastic. It must feel awesome to successfully build something like this.
Seriously jealous over this side of the pond.

As I promised, here are the pictures of the new version of my braumeister clone.










I'm still waiting for the recirculation pump...


Cheers

They look amazing! Great work!

 

[Edak]

Nice work! I see that you have a thriving environment for them so they started multiplying.

 

[Edak]

Wait was that a CNC plotter in your picture? Would like to have the budget for something like that!

Yes Edak, I built this CNC last year. I collected some used stepping motors and aluminum parts from junk. You don't have to spend a lot of money to build it. The most expensive part that I used was the controller board (around US$45 at amazon.com), the rest, as I told you, was found looking around and getting everything that I thought could be useful.

I did not spent more than US$ 200,00 building it (including the old PC). "Low cost high function"

Cheers.

 

[lael]

Wow.... what can you do with it?

 

[Edak]

Most CNC machines I have seen cost well in excess of 1k even if home built

Would you mind posting the dxf files for the front of your control box

Sure, I will.

Here is the last version completely finished.
