Braumeister Clone....

Postby dizzypanic » Sun Jun 28, 2015 21:11

What with all of the excitement over one-pot RIMS systems at the moment, I thought I'd have a go at making something relatively close to the Braumeister or Grainfather probably based on an urn. SO I had a bit of a read and found Matho's thread at Aussie Home Brewers http://www.homebrewtalk.com/showthread. ... 92...looks simple I thought. Bear in mind this post is a bit compressed; this has been going on for a couple of months now.....

A bit of a snoop around ebay and the like got me a 60's baby Burco wash boiler;

Image

This this was £5 and it works perfectly as a BIAB boiler (I had to test it!) . Total element power is 2.5kW and it holds 7 1/2 gals. NO cutouts or safety switches; on means on with this thing!

Image

Fortuitously, my 19l stockpot fits inside and will become the grain pipe, I also bent the handles to just fit into the boile.

Image

I don't know what this thing is but it was £1.50 in a local discount shop and the lip fits the stockpot perfectly. I attached a small frying splatter guard to the bottom with tiny machine screws (M1.6) and a washer in the middle acts as a clamp plate. This was a pain in the arse..I recommend getting one custom made from Inoxia or a similar company.....

Image
Image

A stainless rod off the scrap pile threaded at both ends acts to retain the top plate;
Image

and a marine skin fitting connected to a camlock male provides the connection to the plumbing under the boiler. The small foot keeps the stock pot upright;

Image

I removed the elements and lower shroud from the Burco...(Burcomeister?) and drilled it for another skin fitting and the female half of the camlock; cams removed. A little pump off ebay and a tap flex connector from the junk bin completes the plumbing.

Image

OK, time for electronics. I shamelessly copied Matho's controller which is now an open source project in it's own right see

https://www.facebook.com/OpenArdBir

Controller breadboarded;

Image

I added an extra relay instead of the buzzer because I want to use a doorbell....in keeping with the 60's vibe of the Burco!

Electronics now on verboard;


And a thermowell for the DS18B20 temperature sensor. Its two stainless bolts bored in the lathe then soldered together. Component parts;
Image
Soldered, finish machined and polished ready to glue the sensor in;

Image

That's all for now...

Stay tuned!

Brilliant - I like the breadboard electronics, old school, I'd forgotten what you can achieve without too much soldering :thumb:

I'd rather have a bottle in front of me, than a frontal lobotomy :D

Well I was disappointed ;) Scrolling down those photos I was hoping to see a Raspberry Pi with a wireless connection ... app to control the steps ... phone wakes you to get out of bed when it's time to lift the malt pipe - hmm, you could probably automate a winch too.

An amazing build!

My future plans include not much

Love the look of this my thermopot is starting to look more and more as though it needs re-engineering.

Thanks for the kind comments all, now a quick update...

I put the heaters back on and installed the thermowell into the base of the boiler. Note the extra thermal insulation (cement tilebacker board) to try and stop the electronics from overheating;

Image

And the electronics transferred to veroboard. I managed to find most of it in my collection of junk; the relays come from an electron microscope scrapped by Exeter Uni back in 2003-ish!

Image

I did a quick check for leaks- all dry :thumb: (incidentally, all of the fittings are sealed with gaskets cut from silicone sheet)

Final assembly and sheetmetal work to come. All the best!

Nice one,

How about adding an esp8266 daughter board to host a web interface :)
simply browse to you braudino server to start the preheat of mash liquor on your way home :thumb:

http://makezine.com/2015/04/01/esp8266- ... ompatible/

some esp8266 boards have way more ram and capacity than an arduino uno tho are still limited to minimal i/o pins but hook up with a rx tx serial connection for coms and host a basic page or 2 ;) the esp8266-12 a £5 ebay buy from uk suppliers
It has a 32-bit, 80MHz CPU, 64KB of RAM and 4Mbyte of flash memory on board. Compared with a standard Arduino (8-bit, 16MHz, 2.5KB RAM and 32KB flash) it's a total beast!

LoL. The IoT is getting a bit silly, add a web page to switch it on, what about a nice simple plug in TIMER, no power wasted while it is sitting in "off" mode waiting for the go signal.
Its a solution looking for a problem that doesn't exist.

Thanks for the interest all. Lol Phil that sounds far beyond my coding skills at the moment and assumes that I remember to put water in In the first place! I've not been able to do much on this as I need to fix the welder. Hopefully I'll get the metalwork and front panel finished tonight.....

All the best.

fwiw andy over on Jims has got a basic 8266 IoT temp logger built, and im 95% way thru hacking his code to accept serial coms input from an arduino uno - just got to wire up and start testing.. currently my arduino picks up the temperature and relay status via a Rf link to a hacked brewfridge stc1000+ (v1.08), but that can be changed to get any input..

when complete the whole codebase and limited documentation will be available via GitHub under Hunnimonstr.. feel free to rip off all you like.. pm me for working(compilable) pre beta code.. you just need a 5v to 3.5v logic gate to step down the arduino serial pins to 3.5v and back up from the 8266 (50p board).. :thumb:

Hmmm . . . and I've gone the Raspberry Pi, and Arduino route :roll: . . . mix the two together and more or less instant BrewPi! Got my eye on another fridge as well as the FV Chamber . . . I can see the Maxi 310 being sold on as well as the femto brewery and the pico brewery . . . all good stuff

Can the brewpi spark control this? I'm loving this so far and makes me want to build one too

Not sure about the Spark, but the arduino based one should be able to . . . I think there is even a 'mashtun' fork of the code for that.

after all it's only switching a 10A relay, be that an SSR or a mechanical one

Ok. Apologies all, I have been very lax so time to pull finger out and finish this. I started to make the fascia panel for the LCD and buttons by hand filing a bit of aluminium sheet. It looked ok but not good enough.

So I decided to spend some euros and get a cnc engraved panel done at schaffler (sp?). 30 mins of cad and 6 to 8 days later this landed on my desk today

Image



Original mandraulic made on left and swish cnc version on right. I like it.

Welding and sheet metal bodging tomorrow- can't wait!

Seeing as it was sunny yesterday, I got out the noisy tools and started to get the enclosure metalwork sorted...

Note the high-quality workbench.

Image

That fire extinguisher is usually the CO2 source for the beer fridge, which is currently empty as I have spent too long making this thing and have consequently run out of homebrew...bad planning! For now I can use it as shielding gas on the MIG.

Hole cut out and filed square;

Image

Then I made a card template from the packaging for lunch.

Image

Cut out the bits of steel to be welded into place. Don't look too closely, the welding inside is carp. In my defense its a new to me welder and this is the first time using it on thin sheet. It wont be seen anyway !!

Image

A bit of fettling to re,move the excess metal and the engraved panel fits nicely. Ill weld in some mounting tabs and prep for paint.....now!
