Skywalker Roaster Artisan Upgrade

[@stylianos4570]

Thank you very much for sharing your effort with us!!! I connected skywalker with Arduino uno and it works very well!!! Thank you very much! I'd like to tip you somewhere as a small token of appreciation!Really!! Thanks again!!!

[@inquisitivecoffee]

Very cool. I just did this mod. I've never used artisan before though. Looking forward to playing around with it.

[@lightboy31]

I really want to buy this roaster but did not know how to connect the Arduino board to the skywalker roaster. Another video on that is highly appreciated.

[@nirecue]

@@lightboy31 i did a live stream and will probably do another one.

[@lightboy31]

@@nirecue Thank you so much! I will check out your past and future livestream.

Thank you again for the video. Got it to work but the heater cuts off at 305 degree F. Works fine with stock controller. Any idea why this is happening. Thank you again

[@raymondrios2541]

Great video very helpful. I have the arduino nano and it almost works it only reads bean temp. But does not turn on roaster. Loaded sketch a few times and settings on artisan, plugged wires a few times. Any idea what else can be done?

[@ronnyskaar3737]

I want to do this but have never used arduino before. Though I have made streamers using the raspberry pie. Do you need an SD card in the arduino for the program or sketch?

[@danielacostameza613]

Thanks, it helo me a lot. I followed all the instructions and it works. But I have an issue, some times the machine just stop the heating during the roast process, I read that could ve a lack of communication so the function in triggered the shutdown, do you know how to debbug the cause?

[@clifton4946]

Thank you very much for posting this information. I was able to get Artisan working on my Skywalker roaster! I am coming from using Artisan on a Hottop 2K+ for several years and wanted to try the Skywalker with its larger capacity and unique heating bulb which gives the Skywalker more responsive heat control. The only thing I miss is having the Environmental Temp (ET) logged on Artisan. I purchased a type K thermocouple and was wondering if I could use the Arduino Uno to also log ET if I put the thermocouple into the bean entry slide. Can this be done? Thanks again!

[@nirecue]

Yes you can, the Arduino sending information from Skywalker in the same manner TC4 would. Artisan will communicate via USB/Serial Stream Artisan send out READ and Arduino/Skywalker will send out AT;ET;BT;T3;T4;HTR;FAN;SP ; where (AT)ambient (ET)(BT) - could be reversed, (T3/T4 )other temps, )HTR) heater value, (FAN) fan Value. You would need to add something like a MAX amplifier connected to the Arduino and some code that can pull from CHATGPT.

Man ! Your sérious 👏👏👏

[@elmesaoudizakariae521]

Excellent video, may I ask please how you keep both the controller and the arduino board at the same time? Can you show us the full setup or how you split the connection if you do? Also can you send a new link to the discord? the link on github has expired. Thank you

[@nirecue]

5V from PC usb to power the Arduino nano. The mainboard in the roaster powered by 24V PSU in the roaster.

[@elmesaoudizakariae521]

@@nirecue What about the main controller as it goes also in the same port you're inserting your arduino into

[@nirecue]

@@elmesaoudizakariae521 so the Arduino Leonardo USB Micro port connects to the PC this acts as the serial connection to send TC4 commands back/forth to the PC. The soldered wires on the Arduino Leonardo are connected pins (black/GND) ground, (green/D2 Pin) data+wire and (white/D3 pin) data- wire are stripped from a USB-A cord That USB-A male connects to the USB-A female of the roaster mainboard.

[@elmesaoudizakariae521]

@@nirecue Yes thank you for the explanation. I understood that. What I'm asking is where would the main controller (The box that originally controls the roaster via USB-A) of the roaster go if i want to keep it? Since there is only one USB-A port in the roaster, how do you split the connection? Or do you just get rid of the controller?

[@nirecue]

@@elmesaoudizakariae521 I think home roasters forum has a guide but I am not sure how to keep the OEM controller. I am not a fan of the main controller and use an Elgato Stream Deck instead with Artisan.

[@yousefali4166]

Hey, does this work with an Arduino micro?

[@CoffeeLovesCo]

Nice video, I purchased one of these units from China, total failure, the controllers don't work, the roaster overheated and almost burned down my house. When I contacted manufacturer in China, they said it was my fault, they don't want to guarantee the roasters.. Long story short, I need to control the roaster with something other than the controller that it came with. Would you be able to make the roaster work using the set up you showed here only? with out the controller?

[@nirecue]

@@CoffeeLovesCo there is a custom drop in PCB called Skyduino that we are testing. But so far if you wanna control the machine you need to use the manufacturer mainboard and use Artisan for better control.

[@dbickers]

I ordered the board but I dont know that it comes with a cable, do I cut a usb cable to make my own connections?

[@ariasd2006]

Using the GitHub package and setting it up makes sense. How hard would it be for newbie to learn wiring piece? Any good resources for learning online?

[@nirecue]

An Arduino nano and breakout board with the phoenix connectors would make it a piece of cake.

[@luisaraujo6970]

Hello, where can I get the Arduino board?

[@nirecue]

@@luisaraujo6970 amazon, aliexpress, ebay, Arduino.cc

[@expatinthailand9824]

Do you just plug the USB cable you make and plug into the Leonardo into the back of the Skywalker, or do you solder the wires to the control board? Is the regular controller left in the loop?

[@nirecue]

Computer to the Arduino's Micro/mini/

[@expatinthailand9824]

@@nirecue You misunderstood my question. Not Leonardo to computer side. The cable that goes to the Skywalker roaster. Do you connect that and the control panel at the same time. Or is it one or the other connected to the Skywalker's USB port?

[@nirecue]

@@expatinthailand9824 it goes to the Skywalker USB-A port. You can make a custom wiring y split to hook up both the Skywalker controller and Artisan Arduino

[@expatinthailand9824]

@@nirecue I can do that. I just got my Skywalker yesterday and ordered a Leonardo from China. I just turned it on to make sure it heats and drum spins, etc. I will start just using it with auto assist mode, and I will try my first roast with it today. Later I will make the splitter and try to learn how to use Artisan with it. Thank you for much for the information.

[@The_Coffee_Rabbit_Hole]

does it give you full normal fonctions like bt and et and ror with the power and air level control ?

[@nirecue]

Yeah depending how it's all setup. Custom PCB on the way as well

[@The_Coffee_Rabbit_Hole]

@@nirecue are you a member of the home roaster forum ? I'm not extremely knowledgeable in electronic but it doesnt look to much out of my possibility . My roaster is on the way , I already recieved my leonardo board and I'm waiting for my 24v 40x40x20 fan since I'm on 110v and want to make back to back roast ... anything else I should concider ? I'm use to roast with artisan , if i can use the skywalker roaster with it it would be a nice and cheap upgrade from my hottop 2k+ ... thanks I realy realy apreciate your video

[@The_Coffee_Rabbit_Hole]

​@@nirecuehey ... is there a group buy for the pcb ? Can i also get one ? Just trying to make this as lean and nice as possible before starting back roasting

[@nirecue]

@@The_Coffee_Rabbit_Hole I am but not active I am mostly on the Discord. discord.gg/35D9Xj9w I would start off with cooling mod first and consider doing a E-stop button mod as well for safety. Something that is able to shut off the lamp and keep the drum rotating.

[@nirecue]

@@The_Coffee_Rabbit_Hole the PCB on it's second iteration once we test it out and make sure it works correctly and most importantly is safe to use a group buy on the Discord will happen. Gerber files will be released publicly as well in order for the around the world to be able to use JLPCB or PCBWay to keep creating these boards.
