Quick mod - Air Crazy finally hitting 2nd crack!
Bonsai Doug
I removed the thermostat from the side of the popping chamber (very easy), 'cause I've wanted to at least hit 2nd crack before stopping my roasts.

My first attempt was an espresso blend from CBD called French/Italian espresso blend.

Wow! Things move really fast with this mod. I was well into 2nd crack (easy to hear and differentiate from 1st crack) when I stopped the roast at 8 min. I'm guessing a Vienna roast. Can't wait to make some espresso from this!

What was your typical times to first crack before pulling the thermostat? Wondering how much faster it goes now from start to first crack?

1/2 lb and 1 lb drum, Siemens Sirocco fluidbed, presspot, chemex, cajun biggin brewer from the backwoods of Louisiana

Before the mod I'd get to 1st crack in about 2:30 min. Now, 1st crack occurs about a minute sooner, and 2nd crack starts around the 5 minute mark.

I'm going to slow things down a bit by dumping the beans when they go from green to yellow-ish for 20-30 seconds... then back into the popper.
