If you turn the knobs on my stove too fast, it skips the piezo ignition and just starts spewing gas out.
Wouldn't surprise me if this safety issue has been what has kept other companies out of this space.
But congratulations on their one day goal achievement.
If I may suggest an improvement, how about a manual "off" switch so people can sleep more easily?
And maybe you could add a gas sensor to detect any problems, and try to turn the knob off? And a loud alarm if that failed?
That could turn the product from a liability into an asset.
But what if that $2 processor makes a poor decision, rotates that knob on accident and kills your family?
(In retrospect, I'm surprised we don't have 'smart' stoves which pair up with dishes with thermometers built in to allow seamless temperature specification. Would work very well with induction stoves, I think, since they can adjust the heating on/off much faster than a regular gas/resistance-heating stove.)
We were as surprised as you that this doesn't exist already. A traditional stove is an amazingly capable and flexible device. By adding some simple smarts to the burner control it's possible to do amazing things.
Induction stoves are good, but you might be surprised to learn that gas is even more precise. With gas you basically have infinitely fine control over the flow of energy to the pan since a gas valve is a linear analog control. Honestly, though, whether you have a gas or electric stove we can generally keep temps to within one degree (F) of a given target.
