I just saw this so I checked my 2023 model BC-2 roaster. Apparently, BC Roasters use high-quality thermocouples in their roasters. After setting everything up per the video, my variance was 0.1°F. It is a very informative video. Artisan is an awesome information tool. That's why I support it. Everyone who uses it should.
Would the co-pilot solve the idling problem or do you still suggest an isolator? Just ordered mine and I’m excited to use it! Thanks for all of your efforts to help us CC artisan fluid bed roasters!
No, if you have a ground loop issue, the Co-Pilot won't solve it. I used to offer an isolator as an add-on, but received a bad batch that had a high failure rate, so I'm back to evaluating different units. I'll be sure to include one with your kit at no charge! Having said that, most people do NOT need an isolator, and I don't recommend using one unless it's absolutely needed. So I would still encourage you to do this test to determine your need for one. Thanks for the kind words and the order! -Jason
What probe are you using? I bought a Kaleido M2S roaster, and idle noise on a probe is 1.5C without USB at all (just bluetooth). It feels bad, but I struggle to find reference point.
I'm not sure what probe I was using at the time of this video, but I DO know that a 1.5C idle noise is very high. You should be able to get that down to 0.1C with a system that is free of ground loops and interference.
Could it fix THIS issue, as in the one from my video? 0% chance. Because my issue in this video was 100% a ground loop issue. Ferrite beads on a thermocouple can, in theory, help reduce noise... but they operate as "filters" in such a narrow, targeted frequency, it's nearly impossible to slip one on and have it magically fix something. Instead, you'd ideally need a scope that could show you specific frequencies that are the issue, and then you'd choose a specific ferrite bead/choke to attenuate that. But simply guessing has more chance of INTRODUCING an issue than it does fixing an issue. And in the case of a ground loop (which was definitively my issue in this video), the ONLY solution is to electrically isolate the signal. Ferrite beads don't isolate at all. The USB isolators that I use (and nearly all that are on the market) use an ADUM component that acts as a purely inductive transformer. That is, it 100% electrically "breaks" the connection, then recreates that connection across an inductive field. I hope this helps.

I'll fire up my Hottop later and look at this. Thank you.
Thank you very much for this video and the few other fantastic ones you did in the past. Very grateful indeed. Bravo. I’m ordering my usb isolator.

Thank you so much! That is fantastic. I’ll be in touch to share my progress, I’m excited to begin this new approach!

Could a ferrite bead attached to the thermocouple cable fix this issue ?
