The new Co-Pilot for the new Coffee Crafters Valenta 15 Roaster
In this video, I sit down with Ken Lathrop, the founder of Coffee Crafters, to discuss the all-new Valenta 15 and the new Co-Pilot automation kit that will be included as standard equipment for all V15's. While we were working with a pre-production unit in this video, I can wholeheartedly say that this is a fabulous coffee roaster! Over the course of roasting hundreds of pounds of coffee over two days, this machine jumped to "must have" status in my book.
It features a loft air preheater like the smaller Valenta 7 roaster, but also adds a second thermocouple to monitor the intake air temperature. If the temperature gets too hot for the blower motor, a cold air bypass will electronically open to cool things down.
Once it is fully warmed up (which takes 2-3 batches of coffee), it can handle 15lb batch sizes with ease. Like the smaller Valenta 7, it's cool to the touch, has a wonderful side dump gate, and now includes a cyclonic chaff collector... no more chaff bags to clean!

Fetco brewer hack: disabling the “basket sense” feature!

When brewing with very fresh coffee beans that aggressively de-gas, I find that a gentle stir during the pre-wet pause is an excellent way to improve the uniformity of extraction and saturation of the coffee. The problem with newer Fetco brewers, however, is the basket sensor. If you remove the basket (even slightly) the brewer can’t sense the basket, and the entire batch is aborted. This simpl...

Testing your idle noise in Artisan roasting software

If you use Artisan roasting software to track the temperature of your beans throughout a roast, have you ever looked at the idle noise of your thermocouple or RTD? You might be shocked at how noisy the reading really is. This video shows how to measure your idle noise, and illustrates the DRAMATIC difference that a USB isolator made in my setup (which was suffering from a nasty ground loop).

This is an overview of the bean-cooler on my custom-built 2kg coffee roaster. It uses a low profile SPAL high-output radiator fan. A PWM controller allows for variable speed, and a DPDT switch allows the fan to pull air DOWN through the beans (cooling mode) or push air UP through the beans (de-chaff mode, where it blows the chaff up into the air). Obviously, this is meant to be used outdoors.

1974 Yamaha DT250A source coil testing
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?
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!
This improviment on editing is realy cool!
I think so too!
Amazing explanation. I'm studying PID now and you gave me eveything I need. Thanks a lot
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!
I would recommend going to a forum like yamaha-enduros.com for troubleshooting help.
I'll fire up my Hottop later and look at this. Thank you.
I need to see how the condenser is hooked to the stator
thanks this video helped me a lot to decide to try this roaster I could never afford an Ikawa so I'm find with the ghetto version as long as it holds up and roast well.
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!
Hi @hermetheuscoffee do you recommend this as my first roaster?
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.
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.
Thank you.
Thank you for the video. It helped out bakery keep pumping out the coffee :)
These are old videos. Did you ever get your 250 going?
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.
My 73 DT250 been sitting up for 15 years but going to try to get it running again. It ran pretty good when I first got it in 2002 but then hesitation issues and would stop. Will pull it out and get it running again I hope.
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.
I think I will stay with my SR800 with extension tube.
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.
Thank you for the great video! Do you know what the purpose of the adjustment plate on the pump is (other than getting in the way of me being able to see the roll pin lol)?
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 owned three Yamahas in the 70s with this pump and I never really knew how they worked. They never needed any maintenance and they always worked. Thanks for the explanation.
Thank you for a great detailed explanation!
amazing review !
Will also add in with what an excellent video this is.
Have not seen one go out in 50 years. Those pumps will out live us all. Great video
Nice tutorial but didn't hear you say any thing about the shims behind the cable wheel they play a big part in the pump to .
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!
is there a way to do similir thing using cropster roasting software ? i really like your video .
I'm not a Cropster user, so I'm afraid I can't speak to its capabilities.
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.
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!

Ok. Do you have any thoughts on another air toaster, I think the Brand it's Shenzhen april technology
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.)

FANTASTIC MANY THANKS
This is a great video, Jason! Very stoked to begin testing my own profiles on my Valenta 7 with the co-pilot by my side. Thank you!
hi, hello Can I ask you the model number of this fan motor? Or is there a link to fan motor products? Thank you very much~
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.
Good video. Thank you.
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?
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!
Very good explanation of the so called crash at C1
Hi Jason Is the hole for the bean probe threaded, and if so, is this M6 or M8 or something else?
It IS threaded, but I'm not sure what the thread pitch is.
Hi Jason, I watched your excellent review on this roaster and got my hands on the 150g model. As you said, it is a great roaster for roasting small batches and I found that it even have enough power to go beyond the 150g limit. The temp display is not accurate though but I use Mastech 6514 for temp measurement and connects it to Artisan on my laptop.
@sato2097 it is M6 threaded.
@@hengkaiwee Thanks a lot for the answer!
wow. do you have a video that shows that homebuilt roaster in the back?
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.)
Awesome idea to cool the beans! Any chance of a few more pictures of the motor and bottom of the unit? I'd been keen to build one. Thanks
Great Video...Thanks so much.
Hi Jason, thks for this wonderful video! How do i configure artisan to output the pid values to the phidget hub? Where is this configuration done?
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!
Hey Jason, any updates on this roaster? Are you still using it and would you still say it is worth the price? Are you running it on 240V 60Hz in the US?
Has anyone mentioned the Kaffelogic Nano 7 yet? Roasts ~80-140g (you can set the batch size) and tweak the profile to your heart`s content.
Any updates regarding this machine? I'm wondering if you were able to automate everything
Where did you get the spec for the oil volume per 200 rotations ? Great video btw !

@@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.
