Thanks for the kind words. I've done this system on a commercial drum roaster, but it's not nearly as flexible and reactive as a fluid bed. Drum roasters are often much slower to respond to changes in heat levels, so the tuning of the PID ends up being MUCH different. Yes, it can be done, but it's an entirely different approach that is still very dependent on getting the basics right. For instance, if your charge temp is way off, you're not likely to recover from that. Regarding having high initial power that tapers off later, you can certainly "trick" Artisan into doing this by the design of your background profile. Simply make sure the charge temp of your background curve is well above the actual bean temp. Artisan's PID will see the difference between those two values and apply maximum heat. For instance, if your background roast profile begins at 175 degrees F, your actual bean temp at charge is likely to be well less than this, and you'll get 100% heat that will then taper off as the BT approaches the background curve. Hope this helps!

I think so too!

I would recommend going to a forum like yamaha-enduros.com for troubleshooting help.

Sorry for the late reply. You can consider these two independent systems. You don't need the lighting coil at all to fire the spark plug!

If you have a 240v plug and a way to vent the smoke, I could definitely recommend this. It’s not perfect and it’s not built to last forever, but for the price, it roasts excellent coffee.

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.

Absolutely! Finally got it running like a top. They're fun bikes. I had the full trio of '74 DT bikes... the 175, 250, and 400. The 250 was my least favorite of the three. The 175 is just SO light and nimble, so it's a blast to toss around. The 400 2-stroke is a beast, so the motor alone makes it fun to ride. The 250 feels like it has the same weight of the 400 (and it nearly does) without the fun power advantage.

That’s a good roaster as well. It has less than half the power of the Smola, so it’s limited in that respect. But the convenience of 120v power on the SR is nice.

Are you referring to the silver plate with the hole in it? This is supposed to be aligned so that you can see the pin through the hole. The purpose of it is to actually HELP you find the pin and the dot that it’s pointing to. Maybe your plate is rotated out of position?

​@@hermetheuscoffee Yes, actually have it so that the hole is lined up with the pin pretty closely. But my plate is unlike this one in that it almost completely covers the area where the pin is unless you're looking through the hole. When you're tightening down the nut it's hard to keep it perfectly in line as it wants to move. It's very easy for me to line up the pin without the plate in the way. I'm just wondering if there's another purpose for the plate or if I can just take it off and it will be okay. Thanks!

@@bb8215 I THINK you’d be okay to remove it. I can’t think of any other functional purpose for it.

I briefly touch on shims at the 25:00 mark. If there’s something you feel I’ve missed, please add to the comments to help others. Thanks!

I'm not a Cropster user, so I'm afraid I can't speak to its capabilities.

PID doesn’t kick in until you hit CHARGE, so prior to that, just drag the burner slider to whatever pre-heat value you want… easy peasy!

I don't own one, but based on the price point and specs, I would temper expectations (much like with this Smola unit). That is, it will almost certainly work well and roast coffee. The unknown will be the reliability and availability of replacement parts. (Things like heat elements and electronics would be easy swap with similar parts, but the roast chamber itself is likely unique to this roaster.)

THANKS FOR THE INFORMATION. How do i know if my condesator is bad what are the siymptoms @@hermetheuscoffee

We TRIED doing one during my visit, but ran into some technical issues, so the footage got scrapped. They should be creating a new introduction/demo video in the next 10 days!

I don't recall exactly what it was. I only recall that when I looked for it on Ali Express, I was able to find it and could verify that it was used in small handheld vacuums.

The Co-Pilot is a plug and play solution to automate your 3e. (Which is an excellent roaster!) If you want to go the DIY route then the Yocto path will be a bit more difficult (you’ll absolutely need to re-flash the firmware with some mods). While I absolutely love Yocto devices, I think Phidgets are a bit more user-friendly for DIYers. I have another video on how to do this for Phidgets. Sadly, the Yocto-watt probably won’t do what you’re hoping to do with it, which assume is monitor power of the 3e via Artisan. The Yocto Watt can’t handle that much current. What you COULD do is add a current transformer to it, then apply a formula in Artisan to convert the low-current CT signal to the full current reading. For instance, if your CT reduces current 50x, then you’ll need to amplify it 50x in Artisan. I have the Yocto Watt, so it certainly can do what you’re after… it’s just a pain. A simple $20 ammeter with a donut-style CT on Amazon is an easier approach. Good luck!

It IS threaded, but I'm not sure what the thread pitch is.

@sato2097 it is M6 threaded.

@@hengkaiwee Thanks a lot for the answer!

No, I don't have a video on that, but it's just an old NovoRoaster... a touchscreen automated air roaster. It's a beautiful machine, but the controls are a bit outdated by today's standards. That is, the heat and loft control is essentially scripted steps. It's not PID control. So you can certainly get good results for a given coffee and batch size, but if your variables change too much, so will your end roast. (Variables such as batch size, ambient air temp, line voltage, etc.)

Thank you for the kind words. Please see my video "Controlling RC Servos with Artisan Software". I cover how to configure Phidgets for this exact purpose!

Hi Jason, I am trying to 3D print a servo to potentiomter adapter and see how it works out. If it goes well I would have an automated roaster!

Are you asking WHERE to find the profiles? They ship with the Hermetheus Roaster Co-Pilot. Thanks for the kind words!

@@hermetheuscoffee Where not when, so sorry for my bad english. Ok I understood but I want to use it with a modified popcorn popper and control it by Artisan scope v2.4.8 via an arduino board. thank you for your prompt interaction. kind regards

@@Serrajimed Ah, I understand. This video is really directed to Co-Pilot owners. Of course, the process of CREATING a roast profile shown here is valid for any Artisan user. You don't have to create a button to access a saved roast... you can simply go to "Roast>Background" and load a saved profile from there. Good luck on automating your air popper! There are plenty of ways to do that using things like Phidgets, Yoctopuce, and TC4+ boards, so I hope you have fun with it.

@@hermetheuscoffee indeed, Jason after your answer yesterday I understood that I must proceed differently and I managed to create a profile from the designer and I reduced the points to 5. this morning I tested this profile empty without putting anything in the popcorn. what I can't understand is why it doesn't follow the profile my bt graph is far from being similar to that of the profile. I haven't read any tutorials but something escapes me. thank you very much for your request.

@@Serrajimed Have you watched my other videos on tuning PID for coffee roasting? I go into detail on the individual P, I, and D values. Perhaps it will be useful to you.
