Woo hoo! I just got my electronic pressure control idea tested and it works.
Still a few things to sort out, but I turn a dial and the electronics changes the pressure. The first stop will be variable and adjustable pre-infusion (ie pressure and time) and adjustable brew pressure. Eventually I might look at pressure profiles as well.
The good thing is no fancy pumps are required. These are all off-the-shelf components and relatively cheap (sourced from coffeeparts. Thanks Pedro).
Cheers,
Mark.
