Using the subject of your message post in Google, I found this DIY project:
It appears to be a pretty complete project, includes all of the necessary design files for having the PCB made, the source and binary code for programming the controller, how to modify the toaster oven, etc. ?Seems to be a pretty complete project. ?
The author doesn't specify which oven he used, but did say the oven was a 1300 watt unit. ?I'd suggest that you choose an oven that has a cavity that's appropriately sized for the projects that you intend to use it for. Remember, the larger the oven, the more time it takes to heat the air & objects inside.. ?
Shorter time to heat up means better control of your soldering process.
HTH,
