I don't know if we're allowed to sell stuff on here - please tell me if this is off-protocol and I apologize and will not be offended if it is removed. I reviewed the forum rules and it seemed okay.
I modified a Poppery 1 by removing the thermostat and installing a 1500 watt dimmer on the heater. For safety the heater is still on the switch so it can't be used without the fan running at the same time. I use this to roast, along with a UTC-USB to monitor temperature and to graph data.
I have another modified Poppery 1 and would like to sell it if someone wants it. Otherwise I'm sure a friend will come along who wants to learn roasting and acquire it.
