An Open Source Coffee Machine 99

An anonymous reader writes "The Open Source Coffee Machine [video link] is a recycled coffee machine, controlled by a PC running Beremiz, and using some MicroMod CANopen I/O nodes from Peak-System. This machine have been prepared by Peak-System and Lolitech for SCS-Paris-08 exhibition. It served free coffee during four days at Peak-System's booth, and has been donated to IUT of Saint-Dié-des-Vosges, France, so that students can have fun practicing automation."

      You are missing me trying to figure out what is open about it. I get Beremiz but the software on the Peak-System doesn't appear to be, at least not all of it. I think maybe the firmware for the IO modules is but I'm not positive.

      As for the machine itself, it is more along the lines of a commercial coffee vending machine. Touch a screeen to, I assume, pick the drink you want, and a PC, via IO boards, starts and stops the appropriate field devices to fill the cup.

      It would be nice to see some openness come to

      • Easy there. A good deal of the fieldbuses in use these days are actually open standards. Especially the successful ones. Ethernet/IP and BACnet are good examples. I have participated in some of this standards work myself and You don't even need an invite! That's fairly open IMNSHO.
