Hi,

Thought you might be interested in this thing i built.

It is a Rancilio Silvia, customized with Raspberry Pi computer to control temperature (software PID) and brew.  Allows control and management of the system thru web browser or mobile device.  My favorite thing is the scheduler so I can have the machine nice and warmed up right when i wake up in the morning.

The web site shows step by step how to build it, and all the source code is available for non commercial use.  

http://www.ispresso.net

Enjoy!

That is totally awesome. You have the best of both worlds. Really nice build quality with the Silvia and cool technology to go with it. Any plans on selling a kit?

If there is a lot of interest I would consider some way to make & sell these (or a kit), but right now I'm just putting it out there for the maker community.

All the info you need to build this is on the ispresso.net site - there is a shopping list to get all the equipment you need.  Most of the items are amazon prime.  Then there is a step by step instruction with photos in the DIY section of the site.  Finally a link to the source code and instructions how to get it going:

I am also working on a V2 but don't want to share details until there is something to demonstrate.

Nice looking interface.  Consider using an IGBT for high speed PWM control of the pump and also something to measure flow (to be used to control the pump speed and time).

Consider this a warning, This thread is riding the knife edge of a commercial post, which is forbidden by the forum rules.

As long as this is an information ONLY for DIY and NOTHING is for sale and EVERYTHING required for this mod is FREE OF CHARGE is it inside the lines. Once any part of this mod is for sale,  the line has been crossed regardless of good intentions and a strike will be issued and the thread will be deleted. This includes offering for sale items on the linked web page.

Nothing I say here is to preclude another moderator from seeing it differently and proceeding with the strike and deletion.

Oh dang! I'd love to do this, it'd be interesting to do side by side comparisons with a stock Silvia. I'm handy with components but I'd grab a kit in a heartbeat, just may have to source the parts.

Thanks for the info!

Hi, some people mentioned that they were having trouble viewing images on the site.  I had some images hosted at google drive, maybe there was some issue because of this.  In any event, I moved the images locally to the web server.  Hopefully this addresses the issues.  Thanks

@jonr: Great ideas!  I have a flow sensor on order, but I don't have a lot of info on the IGBT, despite moderate searching.  If you can share any info I would love to explore this!

Thanks

Info about the IGBT and scale I used is available here:

"Computer controlled temp and flow profiling"

IMO, once you can accurately control temperatures and flow rates throughout the shot, you can pretty much match any machine out there (in terms of taste).
