Quite an informative video! I use the Kaleido roaster, and I was sure that the PID could be used to automate a whole roast without being chaotic. Didn't quite understand how to get there, until just now. Anyhow, do you think this system would work out for drum roasters? Also could it work for a set up where the initial power input might be quite high, but later it would be tapered to quite low?
@hermetheuscoffeeАй бұрын
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 was wondering if you could help me please. I'm pulling my hair out with my DT250. It's the same 74. I'm trying to do the timing as you say here. But when I hook up the light bulb it just stays lit all the time regardless of whether the points are open or not. Do you know why this could be happening? I also tried it with a multimeter and I get continuity between the black lead and ground no matter if the points are open or not. Thank you!

Hey so If those coils on the right side of the stator are just for lights, then would a break in one of those lighting coil windings make it not spark. Like can it still be installed and not working and make spark or is the an actual way you have to delete or bypass the lighting coil? Sorry, total newb.

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!

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.
@hermetheuscoffeeАй бұрын
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.

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?
@bb82153 ай бұрын
@@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!

@Presso995 ай бұрын
i use this machine for over 2 years, broke down 2x. The only problem is the power control board. Based on my analysis, it can last for about 70x of roasting, after that it starts deteoriating (power is dropping, so that you need to reduce the load, load means the coffee bean). When you see power is dropping, go replace the power control board (the board that connecting to the power knob). That's all you need.
@sebbelcher26775 ай бұрын
Thanks this taught me a lot. Is there any way to gracefully transition between the pre-heat phase and the roast (from charge onward?) using Background PID control? The only way I've found is to set PID to Manual mode for the pre-heat phase then charge, then go back into Control settings and set it to Background mode - but this is a lot of clicking.

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.)

Hi Jason I am getting a artisan 3e and wanting to use the yocto servo and the yocto watt with artisan software what other yocto device do I need to make it all work, or can this all be done thur the copilot?
@hermetheuscoffee7 ай бұрын
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!

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.)
