follow up......just to complete this thread. the software is switching 8 relais on a relais card. The relais are wired up like in the drawing: That´s all about my automated system. If someone likes to adopt some parts of it or the whole system, I´d offer any help that´s needed so far...

just another pic of the temp probes: on left is the wort outlet and right the water in. Now I´d like to show you how the software is working. You should know, the software gives you most advantages if you do step mashing. For single infusion it would be working as a PID only. First you...

the chopsticks have been a provisional arrangement at first, I didn´t had another choice, although they worked fine; later on I found some SS tubes they were more customizable, but I´m still using these chopstick temp probes for some reasons. Meanwhile I have a large collection of selfmade...

I have learned the ratio is 1.2 :cheers:

nope, I found them somewhere in a shopping mall, dunno exactly where it was, guess it was a Woolworth somewhere in Australia. You know, when a real homebrewer strolls through shopping malls or other sites, he´s always considering wheter things he´s looking at are useful for the brewery or...

you may call me a smart ass, but that tiny little door my motor would take as a stir paddle

hmmm... I guess, mine was operating a bigger one, not such a little one that drives a single door at a private garage. oh sorry, I don´t know what area you live, may be your neighbour has a 20m wide driveway with a huge steel gate ;) just kidding..... anyway, such a stirrer makes life much...

yeah, a sufficient stirrer is a very important thingy on the brewery, I call it the homogenizer ;) here are two parts they would do the job: at right thats a frequency converter (230V in, 3 phases 400V out) that controls the speed/rpm. With that, one can control the motor from almost still...

ahhh.....Screwy old mate, nice to see you here on board :cheers: I see, we´re the "United Beer Lovers" ;) it´s a very small world we live in, isn´t it? @all, thanks a lot for the positive resonance, the thread will be continued very soon. Cheers

Thanks mate, I hope do not bother you all too much with my pitiful english ;)

The Dallas gets connected to the serial port of a computer and it works in the parasite mode, that means, it takes the power from the serial port from the data line. To adapt the one-wire temp probe to the serial port, you´d need the following parts: D3 and D4 are Schottky diodes. I have...

........ Once I found some chinese chopsticks made from SS, cutted and filled with a Dallas looks like that: All of the temp probes got sealed by epoxy, any two componets gluten would do the job. Here a pic how I installed the long temp probe to my mash tun, a view under the lid: You can...

Sorry folks for the delay, I had to sort out the pics for the follow up... here we go: Now that I had a reliable ignition system for the burners, needed only to switch on and off to get it work, I was thinking over how to let the computer do the work. My first demand was to control the...

Thanks Vossy for your positive comment :cheers: I´ve seen your thread where you discribed your selfbuilt HERMS heatexchanger. I gotta say, that´s an awsome, excellent piece of gold, absolutely a Masterpiece. Wait, when I´m going to describe the computer control for the mash temp, may be...

follow-up.... just to complete the gas burner story: that little controller above left in the pic is the heart of all. as soon as the controller get under power, it switches on the i-transformer, 5 sec. later the gas valve. if the i-electrode doesn´t detect a flame within 5sec., the...

yeah, the single electrode is a flame detector, so called ionisation electrode. I´m brewing outside in our backyard, so I have to protect the burners from wind. A pilot flame is a very weak flame, must be watched as well, otherwise if the wind blows out the pilot flame, the gas is blown in the...

that´s what I was thinking too for a long time......... okey-dokey, I´m going to tell you my story ........But sometimes it has happened that a telephone call distracted me, or the Missus asked me something to do for her, so the brew was overshooting by time or the boil was far too...

I see, no one is interested in an automated brewing system, what a pity nevertheless Cheers :cheers:

g´day fellow brewers, before I´m going to introduce my automated brewing system to you, I´d like to know what funktions would be very important at the first place to you. There are so many different brewing systems out in the world, guess there are only a few looking and working...

okey-dokey, but I don´t want to hijack this thread. I´ll open another thread where I´m going to introduce my brewing system. :cheers:
