Remberto,

This project has fallen by the wayside as I now use therm for most of my temperature-control needs. However, the source code is available for download, and the old hardware files are in the “archive” folder of the therm source code. Let me know if you have any questions!

I am interested in your board; do you have any available?

If not; where could I get the code, in order to try setting it up on my own.

I look forward for your comments.

Thanks!

Remberto

For your new version and RTD, Maxim has this MAX31865 chip that seems to make things easy.

Cheers!

I would be interested in purchasing a board if available (to test it in an delonghi ec190). Can you let me know if they do become available?

Anyhow, keep up the good work!

I’m really impressed with what you’ve done here. Like Tom, I have a Gaggia and am thinking of implementing an RTD sensor with the Arduino. I’d definitely be interested if you get a run of these boards.

Keep up the great work!
Josh

Thanks Ethan,
V4 sounds great, please do keep me in the loop if you ever do another print run.
I’m an iOS developer by trade so I’m looking to have some kind of phone interface on my mod with graphing and setpoint adjustment from the iPhone, will drop you an email if I get it going someday as it seems your a Gaggia fan too.
Thanks again and all the best.

Hey Tom,

I actually started designing a new version of the PCB, but I haven’t wrapped it up yet. The v3 PCB works very well though, it just takes a bit of soldering if you want to use a cheap parallel LCD with it. The v3 board can work with RTDs if you use a SparkFun serial LCD (it frees up the “aux” pins), you can solder on your RTD to the aux port with one external resistor. I might look into RTD support for the new board I’m working on, having something which fits the boiler would be awesome.

As for buying the boards, I haven’t gotten any more of the v3 boards made, although I’ve had so many requests that I might get some fabricated soon. I have started designing a v4 board which will be even easier to use, but it’s still a work in progress. If I end up getting a small run of boards fabricated, I’ll let you know!

I’m about to start a Gaggia classic PID mod and found your awesome project,
I would be really interested in ordering one of your boards and wondered if the project was still active?
Also wondered if this board would work with an RTD instead of a thermocouple? Auberins have an RTD made to fit the classic and the Silvia by bolting in place of the thermostat which looks like a neat solution.
Anyhow, keep up the good work!
