got sucked into this all from meeting ladyada at hope and building my first device the sim card reader
wondering if it in some way it would be possible to modify this to have a rca type output to use this for a Music On Hold type project
ive got an old at&t system at work that has this rca port for the music on hold that i would like to build a simple device to plug into that would feed some looping music or maybe some business information
sort of similar to this expensive device , i would like this project to run about 25$ or so to be feasible http://www.easyonhold.com/messagerusb.pdf
the device in the pdf has a usb port to supply music from a thumbdrive but since this is only going to play a few songs or recording in a loop im not sure if i want to have the flash embedded on the pcb or have an external port
any ideas?
