I just completed a round of Silvia mods based on the Arduino microcontroller.  This is an update to the previous "PIC PID NES" mods that gained some attention when I foolishly used an old nintendo controller for tuning a hand made PID controller.  I made a blog post about it that you can see here:

thanks for checking it out,

Bravo Tim! That is fantastic work! And I LOVED the soundtrack!  :-)

PS: the controller doesn't mind getting a little cooked?

This is an awesome project! By far the sweetest, coolest Silvia I have seen. Tim should also mention that his core Arduino software is available at Click Here (www.arduino.cc) . I've been trying to build my own Arduino PID based on his software, and it is almost done. Won't be anywhere near as cool though - no nunchuck and a much simpler 3-button interface.

Tim and Karl...

What an awesome project..... and kudos to you both on the great blogs!

I'm getting set to try it myself... I've got quite a learning curve wrt programing and electronics... but I'm looking forward to the challenge.

Thanks for the support,

Rick

I'm psyched other folks are getting into modding this way.  It's very fun and rewarding, and allows a whole new level of customization.  Andy, good question on the temperature of the electronics.  So far, it's been fine with no indications of stress.  I should probably measure the temperature around the electronics.  I tried to keep everything mounted away from the hottest place above the boiler as well.  A typical maximum operating temperature for electronics is 70C...  Not sure what it is exactly for the arduino etc.

Oh great, a new obsession for me.
Arduino is beyond cool, throw in espresso and you've stepped everything up a major notch. The Wii controller is truly inspired.

Beyond the PID coolness , the built in timer is such a cool bonus. Add wireless/bluetooth connectivity and the world is your oyster.

Thanks for sharing and inspiring,

Pete

I, too, am getting ready to do an Arduino-based PID following Tim's design.  My biggest problem is that I've never done any electronics stuff before.  I think I pretty much understand how all the components work but I'm really hung up on how to power the darn thing!  What have you other guys done?  Steal some juice from Silvia or have an additional plug for the Arduino?  How would one even go about tapping into the existing power?

Thanks,
Mark

Perhaps I should be keeping my nose out of this one, but I'd definitely look into stealing the power from the internals. The PID takes very little current to operate, and obviously all the heating control will operate in place. The only real alternative is to have an AC adapter sharing the wall plate with the machine. Since they are on the same circuit, both will have the same (negligible) effect on line voltage to the silvia internals. Once you install it, it won't work properly without the PID as long as it is configured for PID control, so I would think you might as well just build it into the case and make it look pretty.

Yeah, I've decided that's how I'm going to do it.  As per Tim's instructions, I'm going to split the wire after the power switch and put that through an AC adapter that's tucked away inside the machine, which then plugs into the Arduino.

Thanks,
Mark

hello Tim

i am new here
my expresso maker died a month ago
so here i am reading and learning to help my addiction (projects and coffee)
and i was trying to get more info and knowlege about one of your very nice projects (that is a under statment)  Silvia and Arduino
i have searched the internet for weeks i am not giving up
i have all the parts in place for the full masterpiece  but a crude electrical schematic is fuzzy in my head
only rough notes
i have been running off the video on your blog
please post  soon here or on your blog  
before my head pops
please understand  i dont want to be spoon fed
i am trying to build on what you did and post for others to learn
this project has many fun details
i have not blow up to much stuff yet
i am a tester and hobbiest like you
i get great knowlege and enjoyment from all your projects
thank you very much
