Well, the temperature will not change much, since it can reach soldering  
temperatures with the stock heaters.

I'm adding some to speed up the heating process, so SMD components are not  
subjected to an agonizingly slow and lengthy soldering process.

I will definitely not power it up with the built-in thermostat, since this  
does not measure baking chamber temperature but instead only the  
temperature in the electical compartment.

A LCD display will not fit the small space for controls on the right side,  
so i will probably put it in a separate electronics enclosure. Not bad  
because then it's out of the heat.


But now comes the nasty part - writing some atmel C software that allows  
me to run either a constant temperature or a timed profile. I really wish  
i wouldn't have to do that..
Nobody out there with the desire to make such an oven as well? I would  
provide PCB artwork for a universal controller board in exchange for  
software ;-).
