roZetta™ grew out of an earlier DIY project (BX24-AHT) adding the ability to emulate a TW523, interfacing with the TW523 ports on legacy X-10 controllers (e.g. JDS Stargate, HomeVision, Ocelot, Leopard), translating the legacy X10 TTL commands into Insteon, UPB and newer extended X10 commands, and adding support for an ethernet interface. It, too, was intended as a DIY project with all of the components originally available from Mouser Electronics but changes in their inventory and minimum order quantities have forced me to use several different sources, increasing the shipping cost and complexity beyond what is practical for DIY.

In mid-2008 Tibbo™ discontinued their EM202 NetModule without warning. Its replacement, the EM500, was finally released in mid-2010 but updated firmware to support their GA1000, promised at the time of the EM500 release, only became available in mid 2011. After such a long delay, many of the components used in the original roZetta™ design became unavailable, forcing a redesign of the entire project.

I got prototype boards for a single board design and began testing but then discovered the Arduino - I have been a bit out of contact lately due to some major medical issues so it was entirely new to me. It was an Aha! moment as the modular approach of the Arduino shields was an obvious way to make roZetta™ somewhat immune from sudden disasters like the withdrawal of the Tibbo EM202. I have since designed several Zarduino™ boards and shields that both duplicate and expand on the original roZetta™ design, adding features, additional DIO/ADC channels and support for additional hardware in the process. The results are documented on my Zarduino™ page as well as in a brief overview more specific to roZetta™. Because there are now several boards needed, it will take additional time to order, build, and test prototypes but nearly everything is just an extension of things I have done earlier so I am confident in the result if my health allows me to reach it. When ready, all boards will be available through YourDuino.com (and maybe other distributors).

I also have Basic4Android and an Android tablet and will try my hand at developing a full featured WiFi interface to roZetta™.

And I am also designing a daughterboard for the RR501 that replaces the MCU, adds an optically isolated RS232 port, an optically isolated output for driving IR/RF transmitters, a galvanically isolated 50-ohm BNC antenna connector, 8KB of F-RAM and a battery-backed RTC, turning it into a full-featured X-10 computer interface which can be used with roZetta™ or standalone which I call the RR5x5™ (five-by-five).

The screenshots below are no longer accurate - there will be major changes. The user manuals will require extensive editing to reflect these recent developments but overall it still shows the project's capabilities fairly accurately. The add-on modules are now mostly incorporated in the shields so the price list is no longer valid.

There are Windows, Linux and Mac OS-X interface applications for configuring and controlling roZetta™.
