Hi all,
Having been corretto roasting on and off for 10 years or so I thought it was about time I started paying more attention to roasting profiles. Better late than never.
And so (see pictures).
That's a homegrown iPad app, receiving data via bluetooth low energy from a Raspberry Pi Zero attached to a type T thermocouple via an Adafruit breakout board. Yes, I'm a geek. It works on iPhone too, but I like the big graph. Cost of materials is around $NZ55.
The blue line on the graph is my previous roast; the red line is the current one. It keeps a full roast history of course, with notes, and the data can be transferred between devices or exported to a json file. Lots of features on my list to add, when I get time.
I know you guys have the HeatSnob, but I do like being able to make use of the computer I have in my pocket.
