That's the one! You can get similar boards off ebay too. Augiedoggy used those with success.

OK, after some initial review of piecing together the boards necessary, a lot more research and some guides would actually be very useful! But I know getting the software out there, and documented is much more important!
Thanks to the mods for working with me to get this thread back online. Good people doing the right thing for the forum.
FYI I posted a video on the website discussing some of the basic differences in the types of micro-controller interfaces and how to set one up. It is under Build... Videos.
Great to see this thread back online!
Any plans for a Mac and/or iOS version or support for Raspberry Pi?
As far as native Mac I would have to research it. Thanks for the inquiry!
Just finished watching your video.
Very well done and shows off BruControl's capabilities in an understandable fashion.
Learned something new again - Fermcap - never heard of it before.
You use a pressure sensor for measuring liquid volume? Is that really accurate? If you had it to do over again, would you forego the sight glass and rely on the electronics?
Great video! What are you using for a flow sensor?
Cheers,

No link. PM me with your email and I will forward the spec sheets I have.
No minimums but shipping is expensive if you only buy a couple. I will be ordering a few more so if interested, we can combine.
Brundog,
As I plan out my design changes, I'd like to replace my BCS-460 because of the limited I/O. I found this board (which is based on the Arduino MEGA chip): http://www.digital-loggers.com/plc.html
I like the look of this - it has six 6 amp relays, buit in wifi, and more than enough I/O; at $89, it's cheaper than buying a MEGA, Wifi shield, relay board, power supply, etc. More importantly, it takes up less real estate in the panel.
Any way to verify if BruControl will be able to work with this? It's not in the list of supported interfaces in the manual, but the MEGA is.
Thanks!
I do not know if you plan on eventually also selling hardware items, but if you do I know I would be interested once I am ready to start putting everything together. If not there have been some great links already put out there in this thread, and some others that I have been following. The valves are one thing though that I have not seen links for yet.
Hi WoF,
I saw that unit a while ago... amazing inexpensive for the hardware it includes. I considered picking one up to play with it. I am fairly confident I could get most of the hardware to work. The main processor and I/O will work already. On the native MEGA, the I/O pins are multi-purpose, and in BruControl we give you the ability to pick what you want that pin to be (e.g. digital input, output, PWM output, counter input). On this unit, most I/O is purposely defined. For example, the digital inputs are routed through opto-isolators, so those pins would be inputs only. No biggie - that is why the Interface Wiring Maps exist - to tell you what possible I/O can be used on each pin.
I would have to figure out the Wi-Fi. It is ESP8266, which is currently supported, but I haven't done one where the MEGA is the main processor and the ESP is serving as WiFi only - they seem to be connected via the MEGA's serial line, so I don't know without rolling some sleeves up. The LCD/touchscreen is a no-go. I did some work with the IL9341 and graphic LCDs and found them to be way too slow, even for regular text (like on the order of 1/2+ second per update). You can't have a PID loop interrupted during an LCD update! BruControl currently supports regular character LCDs via an I2C interface (https://www.adafruit.com/product/292). I suppose I could cook you a custom firmware to support the LCD, but I won't take responsibility for performance issues.
Do you know if these are "in stock"? If you twist my arm hard enough, I might get one.
I am trying to stay out of the hardware game! That said, my next project is to put up some more detailed "shopping lists" and how-to's. I realize we need to tell you what works and where you can get it.
I have created some PC boards to facilitate connecting hardware, such as a thermistor filter/divider board, which will allow thermistors (like those used with BCS or STC1000) to be wired in. I have an RTD platform in the works too. In my video, you can see my handmade thermistor board. I have a legit 4-pack, which @augiedoggy is using, and I am waiting for some 6-pack boards to arrive.
