I'll take one!

Alternatively, if I stick with gas, is there an ignitor relay output? I'd need to have the relay on for 2-5 seconds whenever the gas is turned on.

So, I'm thinking about building a pi-based system using CraftbeerPi and going all electric. One question I had was running the pi with a little touchscreen TFT display-- is that supported in the base code or is it some custom work that people have done?

SSRs are already in Fritzing. Search the parts window for 'relay' it's called 'relay-solidstate' There's also a couple of handy libraries around : https://www.sparkfun.com/static/fritzing/ https://learn.adafruit.com/using-the-adafruit-library-with-fritzing/import-the-library-into-fritzing

I'm using a servo with multi rotation, 1520uS is closed and 650us is open. Arduino code here (bugs and all): https://github.com/jrubinstein/brew-PID-propane/tree/automatedBIAB_v1 The other solution that's similar (in python for the Rpi) is from @tob77...

Hi Manuel, Does craftbeerpi support servo output for controlling gas valves? If it does, then I'm in! :ban:

Doing a little thread necromancy... I'm trying to get brewNpi working on my raspberry pi2, but I'm having some trouble. @tob77, I sent you a PM, but maybe better to handle here?

No, I don't have any iodine. I thought I did, but we just moved and it can't be located :( After 2lbs DME and another hour at 145-152, SG was 1074, so I'll take it. Now we boil! :mug: Yeah, I realized that after I posted... I was thinking that some type of powder does have enzymes, which...

tested again - 1054, so i added 2lbs of DME... wish me luck :D

I was at 1048 now i'm at 1053. Preboil gravity should be 1067. Is it worth adding DME now? Will that bring some extra conversion power to the equation? Thanks!

So, I have been running an automated system of my own design, but it's had some trouble, so I switched back to a manual system. Today, I mashed in my stout recipe at 152 and the temp dropped down to 142 while I had the burner on low, so I turned the burner up to 50% and went to sanitize my...

Oh, it's plenty fast, I just mean that heating 5gal of beer takes some time, it's not instant, in which case you'd probably overshoot. I suspect Elco's code needs that lag time, but probably not as much lag time as heating a volume of air to heat a volume of liquid inside that volume of air.

The heating pad I posted works perfectly for me. I suspect the lag time of heating 5-6 gal of beer a couple of degrees dampens the tendency to overshoot. Much more efficient this way, too I think (also cheaper and safer)

Why heat space? Heat your beer! I use one of these: http://www.amazon.com/dp/B000F54AOW/?tag=skimlinks_replacement-20 very effective and cheap for my side-by-side kegerator/ferm chamber fridge
