I would like to have a short range FM Transmitter built that has a built in voice recorder.
The recorder would have a simple button that you would press to record with a built-in mic. No need for a speaker and a speaker for playback. The recording when transmitting would loop forever.
The unit would be powered by a 110 volt plug but needed it small and simple. Just a wire that plugs into the wall. No big DC converter or anything. The unit must be small.
I would need the FM Transmitter to transmit at least 100 feet. Stereo signal would be nice. Needs to be a very clear transmission because it is going to be used for advertising. The box that unit would be housed in can be a simple plastic unit.
This unit is a demo to be used as a test unit for marketing. Once the market has been tested and accepted we would need hundreds built. I have been told by others that this is a simple project. All the components are being used in other items as a stand alone, I just want to make the FM Transmitter and recorder all in one simple small hand held unit.
I do not know what this should cost so forgive me if my budget is incorrect.
