    removed - was obsolete - sorry

    Update: Got the info from Marko Luther (who is the current maintainer of Artisan-Scope) that the TC4 interface with the command structure can be used only if the TC4 is set as main device. So using this methode would not work with other Temp phidgets (at least not so easily). As Modbus...

    @Rob1 As it looks like the "digital-out" VINT Phidgets are limited and PWM does not help here. How about making your own phidget? Just as a first thought: Using an arduino (nano or micro) which you can connect with the RasPi in addition to the VINT hub via USB and create a small arduino...

    Not sure if I understand you right regards the mentioned "... won't respond fast enough". There are 2 half cycles per sine-wave - and 50-60 sine-waves per second (50-60Hz). So for me 0.1 seconds result in 5 to 6 sine-waves or 10 to 12 half-cycles which should be enough for the SSR to do its...

    @Rob1 I use the SSR (mine is - as most of the ones you find on ebay etc. - a zero-cross type) not to "cut" the sine-curve. I just use it as on-off switch, with a time base of 1 second. For 100% heater power = ON // 10% heater power = 0.1 second on - then 0.9 seconds off. As the heater is just a...

    ... please make sure SSR for the heater can manage to switch 250V with enough Amp (10-20A) depending on heater wattage. In most of the cases such boards - like the one you mentioned - are too weak and limited to 2A / 250V. And higher wattage may require cooling of the SSR ...

    Hi @Rob1 .... I found this info on PWM & SSR ... https://electronics.stackexchange.com/questions/233741/activating-ssr-for-an-ac-motor-via-pwm-input
  8. Home Roasters
    @Rob1 Regards use of PWM pinout of a Raspberry Pi - I am sure you cannot connect this directly to a standard SSR (TRIAC). As far as I understood PWM - when not in sync with the "frequency" of main power (50/60Hz) - this would end up in unpredictable results with an SSR. I think you would need to...

    @Rob1 As far as I understood the function of these normal* SSR - they switch on/off only when voltage is "zero-crossing" (= built in function). With that "behaviour" they are recommended for use with PID and heater. As the heating element has a quite inert reaction, this "switch on/off" - of...

    @Rob1 This is a combination of a Raspberry Pi 3 with a 7" Touch Display (xxx://www.amazon.de/dp/B01HPV7M4I) to run Artisan, connected via USB to a Arduino Uno + TC4 Shield for the readout / control of heater. As I came from the Arduino - in combination with a laptop ... the Raspi made the...

    Hi Philip here you are.
  12. Home Roasters
    As my thermocouple has a diameter of 1.5mm => used a 1.5mm drill // used a matching hex screw and "mounted" 3 nuts to get a "grip" for the vice - and then slowly (with a lot of cutting oil) drilled the hole ... (I killed one screw and a drill with the first try - as I was too impatient)...

    Hi @filthynines I saw the message 😀 ... and regards your questions: (1/2) - yes, this is the k-Type and used for BT reading on Artisan (via Arduino and TC4-Board) (3) I use this - as it seems for me the sensor there rarely touches any bean (*I tried to use it as BT in the very beginning...

    Hi, I currently use the Dalian (I have it since 10/2017) with Artisan, latest version. I run Artisan on a Raspberry Pi 3+ with 7" Touchscreen - in combination with an Arduino UNO with TC4+ board to get the "data" from Thermocouples plus adding some additional "functions" like "heater control"...

    Thank you. Sent an email ... so let's see ... will keep you posted.
  16. Home Roasters
    Hello Dave - Thank you for your great advice on Dalian maintenance. I tried to find a source for Ambergrease FG2 in Germany or at least a store with shipping to Germany - unfortunately I had no success so far. It looks like this brand is more "prominent" in UK ... Do you know how I could get...
  17. Home Roasters
    Hi I can confirm it is M14x1.5 - I have tested it with a thread cutter. (and in case this is of interest ... the front plate of the Dalian is approx. 13mm thick) ... I hope this helps
  18. Home Roasters
    @RDC8, In the meantime my Dalian has arrived and found a neat place in my cellar. Thanks to your recommendations I now also own a clamp-on LED lamp, a small fire extinguisher, voltage/wattage meter, a stop watch and a thermometer (also measuring humidity) . My 'bench' is a (cheap) small...

    PaulL I already thought about a "trolley" like this - but wondered about the 'balance' due to the small width of 430mm. But what I understand from you description: it works. This is great to know. Regards "width" of the roaster (incl. cyclone): is it 'overall' 550mm or more 600mm?
  20. Home Roasters
    Hi, As prep. for the arrival ... I would like to put the roaster on a wooden plate with small wheels, to be able to move it around (or put into a parking position). Unluckily I have no clue, if the measures given in the pdf from BB gives the overall footprint including the cyclone. There I...
