Milk foam

It occurs to me that the best way to automate milk foaming for coffee is to have:

(a) A height adjustment capability which varies the height of the steam wand in the milk, and

(b) A microphone that records the sound (frequency profile and intensity) of the milk foaming and adjust the height as per (a) – either built into the wand or external to it

(c) A temperature probe built into the wand

(d) Optionally an adjustment mechanism for the steam pressure in the wand

(e) Optionally an adjustment mechanism for the wand angle and position in the milk receptacle

The system would work by having one of the following:

(a) Simple rules to adjust the height according to the frequency and type of milk foam required, or

(b) Pre-recorded audio profiles for specific foam types and the height is adjusted using an algorithm to achieve this profile, or

(c) Learning algorithms to optimise all the adjustable parameters to get desired foam properties

It would stop foaming at the required temperature and foam consistency.

Note to self only.
