Start roasting man. The payback is incredible. You can get Chinese units for pretty cheap and if you have an electrician friend both legs can be hooked up so their stuff works on an outlet. Otherwise the place I DM’d you has options. I do not want to publicize them because prices may increase and they sell the best green coffee and small scale equipment.
PS. Artisan is the software you want roasting coffee.
IceCreamCalculator is the one when doing ice cream gelato or sorbets.
Both free. Welcome to new hobbies.
