Open Ardbir - Open source platform for brewing process control and automation

Thanks to McMelloW for pointing me to www.3DHubs.com. He's a link to the 3D model.

Only slightly off topic but worth it.
Just searched beer tap on it. You could have a handle made up for each beer you have pouring in kegerator.

Damn you Nigel, don't say things like that to me!

Do you have pics of the bracket?

Were the PID figures ok?

I mean the bracket on the Graingfather with the 2 keyholes. I think of attaching something on the box like a beltclip you have a measuring tape.



The PID figures did very well. P=100; I=20; D=5.  Heated 30L of water up to 70°C  At about 68.5°C the heated started on/off. When it reached 70°C  i ket it for 15min. It stayed between 70.00 and 70.25 all the time. Pretty good I think

Love the group effort with the project.

I think I just blew up my DS18B20. Connected the 5V vice versa. It is showing 84.50°C
Resetting or switching off/on does not change anything.

I have ordered already a new via ebay, but it takes at least 10 days to arrive.

I'd say it's just one of the wires coming loose. Check all connections.

It normally shows (similar to) 84°C on immediate startup then shows actual, within a second.

Checked several all things and all wires. Reseting the box. No I think it is gone for ever. But I have already a new one. This works OK.

My Open ArdBir is finished. Some pictures of the final result.


Everything in the box and wired


All connections. Plug & Brew. Disconnect and replace the original within seconds if needed

Fancy
Are the clicky buttons not better than the number pad?

[pob]

Number pad, potentially easier to splash proof.

Both work, keypad a lot easier to wire up. (Mr AliExpress has some coming my way at the moment).

@McMelloW: have you brewed with it yet? Looking forward to seeing results.

Anyone know where I could pick up a simple 12V DC power supply and connection before the weekend in Dublin city?

Doing a brew on Saturday and want to use my new ArdBir with a mockup of the final circuit. I have a transformer etc on the way from Germany, so just want a cheap and nasty interim solution.

Also, for my version, I'm going to make two boxes. One, which will be connected to all the elements, will have the relays, 12V power supply and SSRs. Then, there will be a control loom going from this to the ArdBir and some manual override switches, which will be in a small compact splashproof box on the brew table, close to the action and the temperature probes.

Should build over the xmas, so will post pics when I do.

I can lend you a big one or what about using an STC-1000 (it has a 12v supply for its relays!)

Will, you da man! I have an STC which I can use for sure. Just to verify, if I just wire one of the relay circuits with 2 blank wires. Then the relay, when active, will be +12V when it's active?

I don't use the cooling relay on the STC anymore, so I can just put two control wires from that relay and off I go
