I love to cook with wine. Sometimes I even put it in the food.


Build one yourself using a PIC, for instance:

Which seem to be derived from the

mentioned by Bill Sloman already.

If your analog mind cannot digest this digital stuff, dig up some 555s and
use an analog meter for the display:

The latter is an old one I ever build myself. Even seem to have a PCB design
somewhere.

A real cheap one is described he
