I have been trying Scott Rao Hario V60 pourover this week. 1:17 and blooming with 2 parts water the first 45 seconds then splitting the rest into 2 pours. A little stirring is included. We like it.

My brew ratio is 1:17 (exactly 59.5 g/L). That's roughly 8.5g per 5-oz cup.

I'm looking to hire someone to teach/help me to find the best roast profile for the 3 types of coffee that grow on my farm in nicaragua. I live in LA, but but could go anywhere in so cal with my Behmor for a roasting lesson. Please contact me if you're in

When your wife thinks 30 grams for a 6 cup setting is strong, you learn to drink muddy water when you are making coffee for both of you.

I use a rule of thumb of 60 grams per liter. 8 cups (1 liter, 32 oz) = 60 grams, 6 cups (3/4 liter, 24 oz) = 45 grams. 10 cups = 75 grams 12 cups = 90 grams

What hardware to buy for aArtisan?

I am confused about what of the options that offered for the Arduino/TC4, I should buy. Any help will be great!


I have electric coffee-tech 1kg Torrefattore, and I do have Fuji PXR PID controller.

Thank you for the help

Could you explain what you would like to be able to do? If you are only after data logging, then I believe artisan supports the PXR and you don't need arduino/tc4. Or do you want to replace PXR and control through artisan/arduino? Do you want to control heating elements and/or fans? Do you already own an arduino? Are you comfortable with soldering?

In summary, the TC4C-BUILT lets you control heating elements and connect your roaster to a laptop to use artisan. You will also need a solid state relay with heatsink and one or more k-type thermocouples appropriate to your build, that you will have to get from Amazon or equivalent.

If you also want to control the fans, then you will also need a ZCD-BUILT (zero cross detector) and a second solid state relay (usually no heat sink required for this, unless your fan motor is large, e.g. 8 amps or more).

If you also want a display on your roaster so you don't have to connect to a laptop to see what is going on, then you also need LCDAPTERC-COMPLETE. Personally, I would only add this later if you find it necessary.

If you already have arduino, then you can buy the TC4-BUILT instead of the TC4C-BUILT and simply connect to your arduino.

If you know how to solder, then you can buy the TC4-KIT instead of the TC4-BUILT and save some money by doing the soldering yourself.

I wouldn't bother with the TC4-SMD, IMO it's worth $10 to make sure you get everything you need in one shot with the TC4-KIT.

In full disclosure, I don't own this...yet, but have done some research. So anyone feel free to correct me if any of the above info is wrong.
Thank you for the detail reply, very helpful.

I do want to be able to control the heating element using Fuji PID. From my understanding it much quicker to change the setting using artisan software then to go thru the Fuji menu system, and I like the ability of running automated cycle. I did buy the Fuji PID, solid state relay, and thermocouples, at later stage I will like to add VFD to control the fan speed.

Is it a must to have TC4 with the Arduino? I have the Arduino, a thermocouple and the connecting board and also the SSR. Could i use the Artisan in such configuration? For me the courier cost will be 50% of the price of the TC4 and is relevant.

you may want to look into our DIY

fo the TC4


go to all frums and scroll to the DY section

It looks like it may only be compatible with tc4, but can look into though like Ginny suggests.


But roastlogger software is compatible with Max chips, if you got one of those, could try that also.

You mention a connecting board. Is it an interface from the thermocouples to the Arduino? The TC4 uses an Analog to Digital chip. The output is I2C bus.

You would have to alter the aArtisan Sketch in the Arduino to make it work with this different interface. Some programming to do.

KKTO Roaster.
