well all you would have to do is run the speaker to two different amps, and use the speaker as a mic,,, maybe have a mom. switch to go back and forth between the op amps.

Multiple User Wireless Method -
Take 2 Cans, or paper/plastic cups, purchase some walkie-talkies.

Place the walkie-talkies in each cup or can, then secure the walkie talkie into the cup using padding of some sort. Cut a small hole in the cup or can where the Push To Talk (Transmit) button is, and you’re all set.

You can now communicate through cans, wirelessly, and with multiple friends.

Yes ppl, your observations about this being based on the kit are correct, which is CLEARLY STATED if you go look at the link. http://www.flickr.com/photos/fotoman/3602044407/
I had the idea for months, then saw the kit, which provided a convenient way to show the fun concept. Saved me time and achieved the objective, for fun! Submitting to hackaday was an afterthought. I’m glad most people see the entertainment value here!

Yep, rundata is right… I built the same kit (minus the cans) about 6 years ago in high school! I still have it in my desk drawer. It’s a simple project that takes about 30 minutes to solder together, then the dude stuck it in a soup can to be cool.

I built something like this using carbon microphones and high impediance speakers. each person had a pair of cans, one to talk into and one to har out of. each pair also had a button and a buzzer. It used 2 pair telephone wire. Black was common ground for everything and the yellow wire was mic out (in [+12v] was the red wire). Speakers were connected to ground and mic out. the button was connected to the red wire and the green wire (ring). the buzzer was connected to ring and ground.

sooo.. each pair of cans had 4 wires coming out.
red—- +12v
black– ground
yellow- mic out (audio)
green– Ring

infinate “phones” could be conected in parralell, and every phone heard what was spoken into any other phone; any phone could ring all phones, thus creating a complete intercom

all made from shit people threw out. battery included.

A piezo for both mic and speaker and some sort of wireless connection would be sweet
