I bought a Variac for use with my Poppery II. I'm all hooked up and will give it a try tomorrow.
Any suggestions for voltage as a starting point? The Variac seems to default to 110 V but the Poppery II mentions 120 V on the bottom.
I tried it a little - way cool to effectively be able to dial up and dial down the popcorn popper, looking forward to figuring out how to best use it for roasting coffee.
Other - we roast a lot of Sumatra and a batch has been taking 15-18 minutes of late when sometimes - when we had higher line voltage, I assume - it would be done in half that long.
