I will be at Hacker Dojo this Saturday at noon. I'll be there to do the Toast-R-Reflow conversion operation in person. I'll leave the completed oven there for folks to use too. I'm not a member, so I can't reserve a room or create an event or anything like that. But I visited (for the first time) this evening and met some folks there who dug it and they said that Saturday at noon-ish was a good time, so that's the plan.
I've already set aside most of the parts. I'll be using the standalone controller and an LCD backpack, but I will eventually replace that with the ATTiny84 backpack design as soon as the boards arrive from OSH park.
