Breville Barista Express - Dimmer mod - Flow Profiling.

I've seen a lot of information about adding a 120v dimmer to the Barista Express to allow for flow control. As a step above that, has anyone thought perhaps of replacing the dimmer with say an Arduino and voltage regulator? This could potentially allow for flow profiling similar to say a "Decent" machine.
For example, you could "record" a manual flow profile, and if that profile yields a favorable result you could "save" the profile as a graph and then in theory "play back" the profile to attempt to yield a similar result.
Personally I'm not technical enough to program the arduino but I can't imagine it would be that hard for someone with a little more knowledge than I.

Just a thought,
Robert

That sounds like a great idea. I have an arduino education kit. I’m going to look up how to make an adjustable voltage controller!!! This sounds so cool to be able to record it

Also. I have done the Dimmer a few times. I don’t have “profiles” but I do make the majority of my shots lower in pressure.
