[hpsdr] [OZY] QFP or BGA?

[KD5NWA]

I've been digging up articles into how to hook up an external 
controller to control the temperature profile of a toaster oven.

  I found one I like, the only mod to the oven is the addition of a 
high temperature probe. An AC outlet is controlled by a AVR CPU to 
power the oven and maintain the proper temperature profile.

SparFun Electronics has some nice AVR CPU boards that are el Cheapo 
and have a breadboarding area to add the circuitry for the sensor and 
the control of a Triac. I will try to build it later in July.

Soldering leaded components in the Toaster Oven is pretty easy right 
now, I would tend to think that BGA packaging will require a 
controlled temperature profile to insure reliability.
