What happened with this cable? This would allow you to route immediately behind the tablet with a small slat hole at the top lip of the machine also hidden by the tablet.

I was going to include these two pics to route cable behind the tablet vs a right angle cable as you mentioned previously, but the above flush mount ribbon cable seems cleaner to me.
These are from the portable audio world:

That cable, it turns out, is really meant for internal (non moving) use and the cable will break quickly if it is flexed. We can use it for the glued-down DE1CAFE model, but not for the DE1.

As to the other photos you sent, thanks for those, but that's not really the problem we're trying to solve. Compact, right angle USB cables are widely available, like this one:



the current problem to solve is how to get the cable from inside the DE1, outside to the tablet, in a way that doesn't cause a water leakage, reliability, or cleaning problem. And looks good too.

Also very pleased to hear the funnel sits well. It's very, very snugly fit to standard 58mm baskets, which you want in a funnel, but could have caused problems in the real world, where things vary more than the lab.

The filter baskets are VST. Haven't tried your funnel on the machine's native baskets but I don't expect any issues there at all.

On the DE portafilter cradle... my application is very similar to yours. I utilize it as a level steady platform while doing WDT. I use a PuqPress tamper or I would also be using it as a tamping stand.

Your portafilter cradel is a great design and a flexible design. In my case no bending adjustment was needed at all.

The funnel fits brilliantly in this Rancilio naked portafilter. The filter baskets are VST. Haven't tried your funnel on the machine's native portafilters and baskets but I don't expect any issues there at all. (EDIT: Just tried it on both and it fits them just fine; the fit on the Rancilio was a just a tiny tad bit closer tolerance.)

Ben Champion suggested we change the group head design to make experimentation easier, which we've now done. Ben and Ray are now trying several different group head diffuser ideas, some based on calibrated orifices, some on turbulence:







All of these are performing well under simulation, and all are much better than the single-hole approach we had (and that you find in other espresso machines). However, it's unlikely that we'll decide which one is the "bee's knees" of diffusers in the next few weeks. We'll likely choose one of the calibrated approaches, because it's known to work well (turbulence is very hard to understand and model).

We'll keep banging away on these ideas in the months to come, and I'm hoping that once the DE1 is out, other people will join in with their own ideas, and have them CNCed (local CNC cost is about $150 for this part) to see if they work better. With lots of people banging on the problem of even water flow (at low velocity) under varied conditions, I'm hoping that a winning approach will emerge (or maybe several). We'll be posting the CAD files for our own ideas, in case you want to start with that and modify it.

Here's what some of the simulations look like. We're trying to have even water flow, but also quite low velocity, to minimise "drilling into" the coffee puck, at varied pressures and flow rates.

Our next set of simulations, which Ben has started to work on, involve simulating the puck's absorption of water. We're hoping to gain a better understanding of what happens during preinfusion through this work.

In the past 48 hours, 23 people have volunteered to translate the DE1 tablet software, and we now have added Swedish, Hungarian, Thai, Danish to the list of supported languages (in addition to Japanese, Korean, Chinese, Spanish, Italian, Portuguese and German).

There are about 40 artistic tablet styles that will be available on the DE1. Instead of doing real work, this past summer I worked with 40 different artists, from all around the world, to create these. The translations are automatically used on all of them. Below you can see some examples of this, in Korean, Japanese and Swedish.

Will someone step forward and do a Finnish translation? Perkele !

Is there a plan about a font in the future?
Korean font in the picture looks like old fashioned.

Will these be CNCed from 303, 304, 316, or 416 stainless steel?

I was mentioning the 180 degree cable so that the cable wouldn't be visible and route behind the tablet vs a right angle connector.


You could then either use a flat cable and put a groove/slat/sliver up towards the top lip. Or a female flush mounted connector there. The tablet hides all of this. I like the idea of the groove, because it will probably be small enough and the top lip will probably hide it from general view unless you are looking for it. I'm not sure how you'd do this, but you could have a blank to cover the hole for those that mount the tablet elsewhere. I like the idea of a flush mount connector because that is a clean look, BUT its larger, can't be easily hidden from view, and you'd need a rubber grommet and cover to protect from the elements if not in use.


I have no doubt that there will be other much better solutions.
