Dear all,
I received many complaints on noisy RoR signals over the year. The ongoing work of Scott Rao and a broken TC made me reconsider my own roast logging setup. As I had collected many different meters and probes over the years, mostly for development purpose, I wonder which one I should best install in my machine.
My goal was to minimize both, the signal to noise ratio as well as the introduced signal delay, especially for the RoR. Thus I came up with a setup that would allow me to compare different setups on the amount of idle noise they produce.
Details are here: https://artisan-roasterscope.blogspot.com/2019/03/on-idle-noise.html
I switched from TCs to RTDs for reasons detailed in the post and I am quite happy with my new setup,
Marko
Hi everyone:
My roaster is apart for mods and it is getting to the point that I
could take advantage of a second another VINT hub. I just want to
check if that is possible, please.
Also, I noticed that there is no mention of Phidget 1136 (diff. air
pressure) on the supported devices page. Has support been dropped?
Kind regards,
-Craig

The info you provide is very terse.
“SF6” is probably http://www.sanfranroaster.com/sf-6lb <http://www.sanfranroaster.com/sf-6lb>
And “Watlow" I assume to mean http://www.watlow.com/products/controllers/temperature.cfm <http://www.watlow.com/products/controllers/temperature.cfm>
My hunch is you maybe just connected the cables without making sure that variables like baud speed, even/uneven, parity, stopbits are all set exactly the same on both ends.
SF should be providing that info / assistance in their manuals / service desk.

Dear Marko,
here the Phidget ‘ambient’ devices seem not to be communicating…
I just spotted this late tonight. Tomorrow I’m off for 2 days.
It’s no a problem here but maybe it’s not just my system where this stopped.
