Connecting soft circuit sensors to a sound system?

I want to make a sensor that will cause a sound system to emit music. There are some 'ibles for making soft-circuit sensors, but I want to make it so that a speaker produces sounds when an object triggers a sensor. When somebody stands on this sensor, sound will come from a speaker. I don't have any experience with electronics but I can learn. Sorry if my explanation is repetitive.

want to add built-in bluetooth audio receiver to an active Speaker

I like to add a bluetooth audio receiver to a Sonos Active speaker. I would like to build it inside the speaker so it looks nice too. I assume I have to get one of the Bluetooth Audio receiver boards like this http://www.dx.com/p/xs3868-bluetooth-v2-0-stereo-audio-module-green-385930#.VVPymNNViuc . I think I should be able to find a 5volt connection somewhere in the Sonos speaker to power this unit and then have to hook it up to the AUX connection in parallel to get the audio going.  I was wondering if someone knows of a good bluetooth audio adapter that can pair multiple devices.  Also any other ideas or suggestions would be appreciated.  Thanks

Custom audio mixer box

I need a device to do the following. One input source for stereo (ipod), one input source for mic. Two stereo outputs to headphones (ipod earbuds). The device would mix the input audio (with a volume control for the mic input) before sending it to both outputs. Is this something that can be bought? If not, anyone interested in making one?

Car Audio Kludge

I recently bought a used car. It has a radio, but no faceplate. While I could probably find a replacement faceplate or even install a new radio myself. I want to see if I might be able to DIY my own stereo out of the bits of my radio I do have and maybe an MP3 player or something. I figure the amplifier and power systems are all hanging out in the box there. So all thats actually missing is the part that acutally makes the audio to send to the amp. Anyone out there know enough about car stereo to confirm/deny my thoughts on this and maybe provide some advice?

Simple audio amplifier?

Alrighty, I'm a n00b to this world but I'm really into it. I just bought a simple amplifier kit and put it together. It is a stereo amp but I am only getting output to one speaker. The only problem I can think of is how i rigged up the inputs. I took a 3.5mm jack and combined the ground from the left and right channels. Can you not do that? How do I fix this without running two individual mono channels? Thanks in advance!
