Light-sensing toasters

Most toasters time your bread’s cook time using a resistor. A current of electricity travels through your toaster’s circuits as soon as you turn it on. When the resistor reaches a certain voltage, the toaster cuts the power and releases your bread. Unfortunately, toasters rarely get the bread toasted “just right.” Every morning I find myself reloading the toaster for another half-cycle, trying to find the perfect toasty darkness.

Let’s modernize this baby boomer appliance. How about a light/color sensor that determines when your bread is perfectly toasted?

Potential issues: dark rye. This could be fixed by adding a “dark rye” option on the appliance.
