How many milliseconds does it need on 240 volts? Or perhaps I can do two in series!
Steve.
If you put two in series and double the voltage the current draw still doubles.
Has anyone done a monte carlo analysis on hotdog resistance? If the resistance changes once the cooking process is complete you could have an auto turnoff circuit.
That somewhat reduces the elegance and simplicity of the design.
BTW My parents had one too. That would have been about 1968 or so. If I recall it does not have a safety switch on the lid.
