Small Rf transmitter ?
i was wondering if there is a schematic of a small rf chip-
or what i need to make an rf chip(i have an electronic class at school)
and will rf transmitter transfer music
wat i want to do is make wireless headphones
i want to have it plug into my zune(mp3)
have the transmitter plug into the headphone jack
and have 2 transmitter receiver in the other 2 head phones area
and make the transmitter receiver run off of lithium or maybe those lil batteries in those red laser pointer
and the transmitter it self would run off the zune power or have a very small battery pack hook to it any
ideas how to do it?
do not reinvent the wheel.
there are many devices that will do as you desire without having to engineer a new one.
you can build a kit from www.ramsey.com electronics or buy a stereo in RF out box from www.partsexpress.com
the problem you will find is that you are very limited to legal frequencies, and then the device my meet technical standards that you may not be able to conform without some serious test equipment (spectrum analyzer!).
