This is another update on my adventures with the Wandboard and the Community Squeeze. I have a first project (still ongoing) that is documented here: http://www.communitysqueeze.org/image_gallery.jsp#Pascal_Hibon
Due to the fact that the Community Squeeze is working great I got some ideas for two other projects for this player in my house. Both of these projects require a Squeezebox that will be mounted behind the sealing driving in-ceiling speakers through an amplifier which also resides behind the ceiling. The Community Squeezebox needs to switch the amplifier on and off based on the power state of the player. So there was a need for a bit of additional electronics and a custom Lua script. The Lua script is driving GPIO_19 on the Wandboard. GPIO_19 simply drives an SSR (Solid State Relays) which powers the amplifier on and off. Below are some pictures of the project: I use a 3.5 mm stereo jack for the trigger output. The two resistors and the transistor are soldered around the jack connector: '[image: http://img809.imageshack.us/img809/8435/triggeroutconn.jpg]' (http://imageshack.us/photo/my-images/809/triggeroutconn.jpg/) This is how it connects to the Wandboard: '[image: http://img59.imageshack.us/img59/9546/triggeroutboard.jpg]' (http://imageshack.us/photo/my-images/59/triggeroutboard.jpg/) And here it is all assembled: '[image: http://img441.imageshack.us/img441/3083/triggeroutwandboard.jpg]' (http://imageshack.us/photo/my-images/441/triggeroutwandboard.jpg/) For those of you who are interested the schematic is attached. And Ill post the Lua script and some documentation to install it in a later post. Maybe JackOfAll can put it all up on the Community Squeeze website. +-------------------------------------------------------------------+ |Filename: RemoteSwitch.pdf | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=14866| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ Pascal Hibon's Profile: http://forums.slimdevices.com/member.php?userid=7969 View this thread: http://forums.slimdevices.com/showthread.php?t=98834
