    Electric Brewing on a PLC - Wiring Diagram

    This thing is so new, I doubt it. Jump on the knowledgebase and search around. There is a lot more stuff now than there was a couple months ago but it is still limited.

    Electric Brewing on a PLC - Wiring Diagram

    I'm using the Micro830. Version 1.01 of their software just came out a couple weeks ago. Version 1.00 was extremely buggy although 1.01 is a vast improvement. The Micro800 series uses a different software suite than any of the other AB processors. It is much different from both RSLogix 5, 500...

    LG 3-MD-HC pump questions

    Well, I read a couple places that the grease was not food grade and not safe to eat/drink. One website mentions that the shaft is made of some material unsafe for eating and drinking. But several threads say "it is fine. Go with it." But all of these sources cite nothing. They just make...

    Electric Brewing on a PLC - Wiring Diagram

    I'll be watching this thread closely. I'm a controls engineer and have an AB processor and HMI I'm playing with for my electric build. I'm already jealous of your panel. Looks nice! My stuff is in a computer case for the time being. I am loving getting it all set up. There is so much cool stuff...

    LG 3-MD-HC pump questions

    I realize this topic has been exhausted but I have spent hours over the last several weeks searching this forum and other sources and have found nothing more than conflicting information with a majority of it being second or third hand assumptions. What needs to be done to a LG pump before...

    DIY variable speed grain mill

    Finally got a chance to brew today.. Ground 22lbs of grain with the mill and my only complaint is the noise. It is quite loud in an enclosed area. I like the speed adjustment a lot. I'm not sure why but I adjusted the speed a couple times during the crush. Sometimes it seemed to need a speed...

    DIY variable speed grain mill

    I'm fairly sure this is it. I'm not 100% on the resistor value. I tried to read it from the pic I posted as I don't have the device with me at the moment. Those resistors have a different band scheme than I am accustomed to. I am going to experiment with adding another (different style) diac...

    DIY variable speed grain mill

    The 1/2" chuck was way too long. I was going for compact so I took it off. I ground down the 1/2" threads coming out the drill to make it shorter and made a coupling with a 1/2" bolt which allowed me to attach a lovejoy coupling to the drill. I ground the head off the bolt and used the 1/2"...

    DIY variable speed grain mill

    I cut the handle off the drill. I surely have some more photos around here somewhere.. The drill is this one here.. I got a coupon off the internet which brought the drill total down to ~ 35 usd. 1/2" Heavy Duty Low Speed Drill You can see that there is already a spot on the side which makes...

    DIY variable speed grain mill

    These circuits (a SCR with a DIAC) are very popular. There is a lot of information out on the nets on different flavors and varieties. I didn't post this intending for others to be able to replicate it through the pictures (especially considering there is no way to tell the DIAC isn't just a...

    DIY variable speed grain mill

    This circuit has the same concept as PWM but you are using the sinusoid from the wall outlet to trigger the pulses. The pulses apply 110 volts to the motor windings. Varying the resistor varies the time that the ON pulse comes on in a single sinusoidal period. The motor is a DC brushed motor...

    DIY variable speed grain mill

    Yet another motorized grain mill. The speed of the mill is varied by a knob mounted on the box with the ON/OFF switch. Max speed is 550RPM. You can't see my hand operating the potentiometer but you can hear the speed changing quite clearly. Having learned some things, I would say i could do the...

    Mash and boil now, boil later.

    It sounds like I'll go that route unless someone chimes in otherwise. I was planning to brew Saturday but ended up throwing my starter in the fridge on Friday. The yeast were still active when I put it in the fridge. Should I feed them again or just pitch it like it is? I'm planning to pitch...

    Mash and boil now, boil later.

    I had a family emergency come up and it has put me in a bind with my work schedule. I have two short evenings to get a batch mashed, boiled, and in the fermenter. What is the best way to handle this? I plan to bring the wort to a boil and chill it before I store it for the next evening...

    First recipe suggestions

    I am putting together my recipe for my first non-kit brew day. All I know for sure is that it will be bottled and it will be a 10 gallon batch. I basically started off by doubling all the ingredients the 5 gallon sierra madre clone from Northern Brewer. Just by doubling the ingredients I got...

    First all-grain. Please critique.

    A couple questions for you guys.. I let the sierra nevada clone sit in the primary for two weeks. It was completely done fermenting and had apparently lost its CO2 content. I racked it to the secondary and popped an air lock on it and I have equal pressure in and out the carboy. Would it be...

    I missed this earlier - I went with that chiller design because the copper was free. I was interning at a place and helped them clean out some of their shop floorspace and they told me I could have it. It is 1/2". The bends at the bottom have 90's since the bend would have kinked with a pipe...

    I was really confused about the mashout step. I read around and really didn't see anything that described the "proper" way to perform it. I finally decided to drain and then introduce the 169 degree water and allow it to sit for 10 minutes. Next brew I'll introduce the hot water for mashout...

    The foil is just tin foil. I always cover it the last few minutes of the boil to keep any undesirables out of the wort. I add some foil about 5 minutes before the end of the boil and another piece right as I'm cutting the burner off to take care of the remaining opening. I just like having...

    First all-grain. Please critique.

    Since I am obviously doing everything properly.. :ban: On a more serious note, I did have some questions about the mash out. I was scared to heat the sparge water higher than 170 so I literally hit 169 and poured it in the mash tun. But my final temp wasn't even 160. The grain was 151F when I...
