Sometimes you need to cook something very long until a specified weight is reached. For a demi-glace (a special sauce) you need to dehydrate it from 12 liter to 200 ml. Therefore I build this intelligent weight scale which can switch off a heat plate, when the given weight is reached.
The glaciator consists of an arduino nano, three load cells with hx711 A/D, an LCD and a buzzer.
You put your broth on the scale and let it heat until you have demi-glace.
This is the prototype:
