I put mine in a water bath and go cool the first few days around 60-62, at least until activity "calms" so I'm not overflowing krausen from the blow off tube lol the. I'll ramp to 70ish for another week, this gave me intense bubble gum smells during fermentation but the beer was very banana and...

I bough quite a few batches worth of grain and had it crushed back in March, well I was taking 20 credit hours to get my degree, graduated, and got a job at Chrysler where I spend the majority of each day. Needless to say, I've had a bag of crushed grain sitting for a 3 months, its gonna be used...

My eherms and boil kettle run on an atmega 328p which is the same as the arduino uno r3. i have like 4 pins unused still

My system is thermostatic, a herms tho. I have a 5500W element. And 13 gallons in the hlt. HLT is 4 degrees above set point, my pump kicks on when the temp drops 0.1 below the set point, turns off at .6 above set point, drifts to 1.0 degrees from turn on point. Perfect 1.1 degree window at max...

You could start with arduino, its more of a development board designed for beginners. But if you want to really impress the tech world, be more customized, and/or take on a bigger more challenging (arguable) task - learn C, not arduino 'C'. Then again I'm in engineering school. I made a semi...

And yes Dallas/maxim 1-wire is way different than i2c.

I don't seen any reason to sample any faster than about every second. The biggest problem is going to be the integral. The more often you sample the faster the integral will rise and possibly hit the maximum I term or overflow if there's no overflow protection. I don't know arduinos PID code...

For those of you who code your own herms/rims systems what frequency do you switch the element at? I have my system at .95 Hz using the 16 bit pwm with a 16MHz crystal and prescale of 256. My concern is how the instantaneous power surge of a random turn on SSR could affect the system. Worst case...

Im a senior at Purdue CoT in Kokomo, also making brewing system. Although we aren't in teams. For cost purposes I'm only automating the mash. I currently have my system set so the HLT maintains a set temp x degrees higher than the set mash temp, and the mash temp is controlled by turning the...

Watch his presentations/videos on youtube. Very informative. His Brettanomyces Project website is also chalked full of info. Sometimes it can get dry and I'll tend to day dream but very in depth. He knows what hes talking about. Boiler Up!!

Worth every penny. Boiler Up!!

I bought a used Molon 63rpm motor based off somebody elses thread about using it to stir the HLT water. The motor is "internally thermal protected" but when looking up a data sheet for the motor its primarily used in copy machines and small non heated applications. Once my HLT reaches a high...

I've got a rather long program. I'm reading adc values and using 2 ds18b20s I've got my code for that wirrten. I'm using an ATmega328p chip, coding in c on atmel studio 6. My program will have time dependent outputs, when to switch from one mode to another, displaying a countdown, and such. I...

Sounds spot on.

Yeast will be totally dead. Obviously I've never done that but I would think the higher then temp the better the extraction, since boiling seems to work good lol I wouldn't suspect any tannin flavors. But possible grassy flavors. Try to pull a sample of it and taste it.

Brewed my first saison, 80%pilsner weyermann 20% wheat same Wyeast saison yeast not 3711 but the other one Brewed in feb and then bulk aged this summer with jolly pumpkin dreggs Tastes good but has a slick oily mouthfeel that coats my mouth. This beer is 8 months old now. It almost has a...

You may be suprised how fast the slow boat from china is lol I ordered a 2 relay board for 4 bucks free shipping and a knock off development board for 10 bucks both shipped from shanghai via ChinaPost and only took 5 days to indiana.

If you stick a belgian cork in too far and cage it properly will it self correct with the added carbonation

I'd remove the o ring and any Teflon tape first but its fine to weld. I've got the same issue and am about to do that to mine.

Great links. They are basic but its where I need them. Like serial communication 101. The only thing I've used it for is talking from avr to a hyper terminal, a serial lcd screen and reading a ds18b20, and that doesn't help on the gui side of programming in c#
