What part of this process (going wrong) causes the house to burn down?  That's an important question in this discussion. :-)

I guess along with that -- which part of this process (going wrong) electrocutes me?


Frost Said:

I ran a P2 for many months with a variac on the heater and the fan directly plugged into 120V. .....  There are no lugs to connect so wire nuts or electrical tape and solder are required. I left the fan with it's heater coil intact and ran that to 120. The heater coil on a separate plug went to the Variac. (they share a common, so polarity must be observed.)

I appreciate the P2 advice.  Thanks so much! I find the above quote slightly over my head. I can't visualize it very well, especially what "plugged directly into 120V" and "the heater coil on a separate plug" involves. Is there a link with photos that can make this more concrete?

Modifying the P2 does not have to be so complicated (for reference, Ron has them backwards: the P1 has the 120 V fan.)  I ran a P2 for many months with a variac on the heater and the fan directly plugged into 120V.
The wiring is a bit more tricky (if you don't usually work on stuff like this, please get some help so you don't burn the house down) There are no lugs to connect so wire nuts or electrical tape and solder are required. I left the fan with it's heater coil intact and ran that to 120. The heater coil on a separate plug went to the Variac. (they share a common, so polarity must be observed.) The P1 has a more powerful and durable fan motor, and more powerful heater (which you don't really need for roasting). I have gotten years of service out of a poppery II, so don't let that stop you.

You're right, I reversed them.

I had a couple of P2's and a P1. I was just about to dive in to all the modifications when I read the thread on HGDB roasting. I went out and spent fifteen bucks on a heat gun at Harbor Freight and grabbed a wooden spoon and steel bowl from my wifes cupboards and I was off to the races. Much more control of the roast and I have roasted up to one pound at a time. Though I found at one half pound I was able to control the roast much better. I gave one of my poppers to my brother and one to my cousin and the P1 is collecting dust.
HGDB was much more fun and much more productive. Then came the Behmor,,,I ended up spending a lot of money anyway but I have a nice Behmor instead of modded out poppers roasting 100 grams at a time. Try HGDB, its only a fifteen dollar investment, when you move on you can always use the Heatgun for its intended purpose.

Well, I already use the rotisserie drum on my grill and I'm somewhat satisfied with its results, but I'm curious to try this method that so many people seem to find satisfaction with.  From looking around, the air popper method is very popular, so I want to try it and compare results with the rotisserie drum.

Flyrod - if you have a P1 lying around, I'd be willing to take it off your hands to avoid buying a solder gun.

This morning I found the Engadget directions on modifying a P2.  I'd be open to any commentary on their method.

From the Homeroaster.org PopperyII thred:

Here's a schematic.  The Router Speed Controller (find them cheaply at Harbor Freight or EBAY) is optional and is used to decrease the heat from the heating coils.

NOTE: No variac is needed in this design.
