Florida east coast here! apocalypse coffee is my favorite local roaster they do a lot of different origins/roasts, and their seasonal options are usually good.
black cat coffee is also pretty good but I've only had one bag from them and I need to try some of their other options.
Seconding happy mug although I buy their greens and then just roast it at home in an sr800 It's hard to beat the value of 4-7 dollars a pound even considering the 10%-20% weight loss after roasting
You can have this feature on linux pretty easily and I think windows has it as an option as well.
I use the Freshroast sr800 and greens from happy mug. There are roasters near me but it's much cheaper to roast at home and I can buy larger amounts of green and keep it around the house for a lot longer than roasted coffee.
I'm still trying to dial in the roast times I'm not sure exactly how long it should take me for the various types of roasts and I've been thinking about drilling a hole in my chaff collector lid to add a thermal probe so I have more information to work with.
right now I'm doing light roasts anywhere from 6:30 to 7 minutes and dark roasts are taking me about 10 to 12 minutes but I usually only barely get to rolling second cracks in the darkest roasts.
