Re: Recording 1st crack with mobile

Re: Recording 1st crack with mobile

I've been wondering recently whether I can write a small program that would listen to a stream of sound data and detect "first crack". That way you have a pretty consistent way of noting first crack (right now, I don't trust myself to do it manually, consistently). So far I've played aroun...

Re: Understanding roast profile

Hi emilesilvis Thank you for this. I am looking at the logs and they are actually tracking fine. I would make an adjustment, up the preheat power by minimum 100 to give you more momentum through the 3 minute mark. It looks like the coffee in log 10 is responding to the fan profile just before 5 min...

Re: Understanding roast profile

Hey, I had a look at the logs you sent. The curves looks a bit strange for 1.3 that it is not following the power curve very well. Is this something you are able to replicate or was it a one off? Did you turn off power of the machine when doing back-to-back roasting? (you should leave it on) I have...

Re: Understanding roast profile

Hey. I can’t pull up the graph as I am on my iPad. Is it the same bean you are roasting and is it the same load? I.e is one of them 120 and the other 100g? But you are correct: if these parameters are the same the lighter roast should be quicker. Exactly the same green bean and exactly the same loa...

Understanding roast profile

Hi all. I very recently started roasting on the Nano 7 (I've roasted about 10 batches so far). Loving it so far. I noticed something interesting the last time I roasted. I had the following sequence of roasts, all on the Raost v4 profile: Logs saved on NANO7 2021-11-02 22-06-36.png What confuses me ...
