I have a strong hunch that most of the PID controllers which are advertised are actually not PID controllers. They are probably all microprocessor based given how they function and the fact that the cost of microprocessor based controls are probably less than actual analog PID controllers. The...

Without knowing the specifics of your application or the specific controller you are looking at, I can only speak in general terms. PID controllers are analog devices which produce analog outputs (like you learned in class). To build an actual control system for an industrial application you...

July has been a busy month at work, which has significantly cut into my time available to work on this software, but I did manage to cobble together some software to build my hops, fermentables, yeast, etc. databases in BeerXML. I would like to build some real databases before I get to far into...

TheFlatline I haven't put much thought into my database back end. I do expect my database to be decent size, but it shouldn't be unmanageable. Most of the variables I want to monitor would not need a high sampling rate. (e.g. the mash temps would not need to be sample at more than 1 hz and...

kladue What are your areas of expertise in brewing systems and process control? I have to admit, I'm alittle short on brewery development/physical systems knowledge. I might be interested in picking your brain when I start building my brewery. Yuri_Rage I've never heard of Arduino and I'm...

moger777 I understand the concepts of open source, but I don't want to release the source code. Just because I give the software away for free doesn't mean I can't make money off of the project. By releasing the source code, I decrease my ability to generate revenue in the future. Also...

k1v1116 Keeping it closed source give me much more control over the software and allow the software to retain much of its value. kladue I plan on building my own brewery control hardware. Otherwise I will probably use a data translations I/O system, I really like there products and...

Bobby_M I have tested both Beersmith and Beertools and neither has what I want. I will admit, for the average homebrewer the additions to the software I want will not extend the usefulness beyond what is commercially available. For the devoted brewer, the ability to automatically log and...

I hate Java. I hate every aspect of Java. I never write code in Java. There I said it. I have strong opinions on the languages I use and the code I write. I typically use C or C++, but I am exploring my options at this time. I would initially release it as a windows product, but porting...

To start off with I apologize for the length of this post. I don't know if the "General Techniques" forum is the most appropriate place to post this, but I hope to get feedback from experienced brewers who may be running into the same problems I am. I have been using ProMash to calculate my...
