So my coffee obsession caused me to build another machine.  It started with some spare parts I had around but really came together when I decided to build a custom espresso machine from the ground up.  Since my current custom espresso machine is donating the parts, I wanted to have something to make good coffee in its place.  Thus I threw this together for fun.

Surprisingly, it makes really good coffee.  That is since everyone who saw it on my workbench thought it was a bomb...

Wow, wait a minute, I think I saw a picture of this on "America's Most Wanted"!  :-D

Its refreshing to see real ingenuity like yours on CG outside of the usual modified popcorn poppers.  :)

Tell us how it all works.  Do I see a pressurized air / hot water chamber there on the farthest right of the machine?

If it were mine I would be a bit paranoid about posting it to the Internet as a visit from Homeland Security would surely follow!  ;-)

How fun!
A lot of great vision there!

It may be that I just need to find my glasses but I had a hard time guessing what was what but what an outstanding assembly of parts!

I would like to see more about your "invention" :D

I had one of those...before I got rid of my Meth lab!

I think we need a video of it in action. I think part of it came from a Keurig?

Thanks for the positive comments.  I'm planning on making a video here soon.  It is kinda hard to see well when I have to post such a small picture.  The funny thing is a friend of mine worked anti-terrorism for the FBI and I have a few friends in similar positions.  I haven't shown them yet though.

So I came up with the idea when I started it a while back and when it was almost done I thought I had a patentable idea.  Then I randomly came across the Clover and ultimately that led me to the Trifecta.  So I actually came up with the idea without knowing about the trifecta.

Here's the basic flow until I can get a video of it or some more detailed photos.  I had 3 Keurigs floating around after I closed my studio, so I parted out the more expensive on that is actually quiet and has a larger boiler.  I adapted a water bottle and with the solenoid valve and ball valve I can transport it to a job site upside down and no water will leak.  That was the reason there.  I made up a special thermocouple that reads the internal water temperature and added a PID controller for accuracy.  I ditched the electronics and wired up manual controls for the pressurization and fill pump.  Then I came up with a clear tube to fill with the grinds, hot water and to slowly bubble in pressurized and heated air for better saturation.

One goal was to introduce constant temperature water. For this the Keurig boiler is perfect since once you hit the target temp, you are using air to push it out so there is virtually no temp drop in the boiler.  The next was to saturate the coffee evenly in the water, so bubbling air was used and it is available from the same system after the water level drops.  With the current brew tube, it is inverted when ready to extract the coffee from the grinds.  A little pressure is added again at this point to speed up transfer through the filter.  

It's fun to use and like my wife said this morning when I showed her how it worked, "It's like a science fair or something."
