Not to be negative?!
I don't think it was intended as a full featured system, it's clearly thrown together on a breadboard as a demo.
Nor is your comparison fair, because (for example) TeensyPi and BrewPi both piggyback an Arduino (or similar) on top of the RPi because of its limited I/O capabilities. This demo uses BBB on its own.
I've never understood this concern regarding limited I/O on the Pi for brewing purposes. For what's being shown in this demo, no Arduino is necessary to make a Pi do the same thing. I run my entire hotside brewery on a standalone Pi using 3 pins total (1wire, HLT SSR, BK SSR). For dual-stage fermentation control you'd use the same number of pins, and for single-stage fermentation you'd only need 2. Where's the I/O limitation come into play?Not to be negative?!

BBB is certainly a great board as well, fwiw.
No worries, I don't believe the RPi is the end-all-be-all for brewery equipment, I just happen to use one in my pilot lab and will be using one in my commercial brewery once permits are finished.Without wishing to put you on the defensive BBB is better hardware in other respects IMO. Industrial grade TI chip versus mass produced Broadcom with dodgy USB and proprietary documentation. RPi power supply issues.
But we are making beer not nuclear weaponry
I have a BBB and m using it for a lot. It controls my rims tube via a pid, as well as controlling my pumps (3 12v and 1 120v), and I can control the flowrate of the 12v pumps with pwm. Each of the pumps has a flowmeter so I can see flowrates and track transfer volumes. I also have four DS18B20 temp probes to track all my temps. All in all , I think the BBB has a lot to offer to brewers (though you obviously have to be able to program them, which can be a barrier).
