I have the knob off my first oven. When it burnt out my landlord opted to buy a new one instead of getting a new coil so I swiped the knob. It was the oven and stove I taught myself to cook on, I wouldn’t be who I am today of I hadn’t had to spend every night guessing the temp from that worn out knob.
I use this for CAD! It’s actually kind of frustrating because I often find my brain uses techniques that I can’t replicate using the controls on cad software.
