DIY Coffee Roaster Update 5 - Cavite, Philippines 

Artisan Scope running on Raspberry Pi computer, 7" touchscreen display, Arduino NANO x3, NEMA23 motor + driver, high speed blower & cyclone separator for chaff collection. 2kgs capacity.
It is messy because I have the blower pushing the chaff out instead of sucking it in, because the bean cooler has a plastic floor and I don't want it to melt. The floor is plastic because I can't go to Manila to get some stainless steel perforated sheets, because of Covid-19.
