Computer Controlled System

[quaboagbrewing]

Has anyone built a system using PC to control everything vs building a control panel? I have been looking at the cost to build out a control panel to run my 10 gallon system but through my work I have access to a ton free older PC's that we retire every few years and was thinking there must be a way to use a PC to control the system. Maybe adding a USB Hub with USB Temp Controllers? Has anyone attempted or accomplished a system like this? I'd just love to find another use for these older PC's since I can obtain for free.

You may find some National Instruments cards on eBay, after all the PCI slots you will need there may a cost issue. Also you need to find a copy of lab view and learn it.

You can use the PC to run the programming software for an automation direct PLC.

Load Linux up on the computer, and use DS18B20 / DS2406 1-wire parts for monitoring / control.

Here's how.

You can also use the computer as the control station with my TeensyNet.

Good idea, I'm just not a fan of one wire stuff.

MIght be a bit penny wise / pound foolish if the cost of (even used) PCI cards outway the cost of something like a beagle bones black running Linux with the I/O already available on the board
