Featured Projects

 

 

CEC to USB and RS-232 converter/bridge, connects to an HDMI cable.

Latest assembly has arrived, small orders can be fulfilled in less than a week (typically 1-2 days).

Native Android application(s) that control the Yamaha RX-Z7, RX-V3900, RX-V2065, RX-V867  (and RX-V1067) Networked Receivers

 

Both receive and send hex-codes on the single wire CEC bus present in HDMI cables.  The USB tty (serial-port) device is compatible with both Windows and Linux without additional host drivers. More info.

NOTE:  in partnership with ValkyrieTech, beta level software is available that adds CEC capability and control to a Windows 7 HTPC.  This HDMI to HTPC integration will allow your HTPC to control the volume of a CEC enabled A/V receiver, power on and off the TV, and automatically switch HDMI inputs.  More info.

ALSO NOTE:  for home-theater PCs & home integration enthusiasts, there is an alternative approach available only from RC Aware that bundles an EventGhost plugin with a custom HDMI-CEC bridge ( “HA” version).   Please be aware that the RC-Aware “HA” version is NOT compatible with ValkyrieTech, and the bridge sold on this website is NOT compatible with RC Aware.  More info.

These native Android applications will operate all the zones of a Yamaha RX-Z7, RX-V3900, RX-V2065, and RX-V867 (and RX-V1067 using the V867 version) receivers.  Far simpler than attempting to use Yamaha’s web page interface, this application easily controls volume, source, sound modes, the FM tuner, and the PC/MCX interface.  More info. (**now available on Android Market)


Comparison to Yamaha’s Android offering:

Basic interface, fewer fancy graphics, larger buttons, less screens.  As a result (in my opinion) much easier to navigate and use.
