We are currently working on the design of the chassis for the café version of our decent espresso machine.
We need to make it larger in order to enable steam during brew, as well as twice as powerful steaming. We also want a little bit more space inside to make it easier to repair in commercial environments.
The café version will be capable of sitting on a countertop or going into an inset bracket, where it becomes flush with the countertop. I quite like the inset look, but I don't want to require it of people since it requires a much larger cut into their work surface.
With the café version, the tubing goes directly downwards in the back has a second panel which hides all electrical and water connections. That way the back can face the public.
I'm also moving to a significantly higher-end Android tablet, this one featuring an 11" screen (vs 8") and 2560x1600 resolution (four times the normal tablet we use). The screen is made by Toshiba and is really clear.
The steam wand has also been redesigned, specifically to enable faster in/out movements, and also to make steam 1 Liter easier. And this should all support hands-free steaming, too.
The cafe model needs to be able to work unplumbed, plumbed to water tanks, or plumbed to a pressurized water source.
Our next challenge is trying to suspend the drip tray cover on four load cells so that we can invisibly weigh espresso and not require a scale. I'm not sure yet how to do this in a way that isn't ugly. There might need to be a modification to the aesthetics of the side view.
This model will be 220V only.
