Re: output from a cell phone?

Well, think about it. How does the cellphone do what it does. It converts sounds into a electrical frequency(ever seen an ociliscope?), broadcasts that via the radio to a signal amplifier, and then that boosted signal is rebroadcast out via the radio, all of the rest of the cell phones in the area are hit with this signal, but only the reciving cell listens in. The circuitry converts the radio frequency back into an electrical frequency, which is then sent to a magnetic piston that pulls and flexes a special surface. which resonates to make sound

If you removed the speaker, and completed the circuit to something else, it would get a variable frequency depending on the sound produced, ie touch-tone phones, or dial-up internet. Each of the different keys makes a different noise when you touch it. this corelates to a different electronic frequency for each key. If you isolated these frequencys, you could use the numpad on your cell phone to steer, and use functions. Likewise, you could have the microphone on the reciving cell phone replaced with something else to get feedback, remove the speaker on the controling cell phone, or use a headphone jack(dosnt hurt the cell any), and hook it up to a computer.

Basically, this all comes down to changing media. Converting data to frequency, to radio, back to frequency, to data out. Of course, the whole idea violates warranty and will rack up a really big bill. But, with global communications, and with the advent of picture phones, you could have a robot that you could controll from anywhere on the earth. Oh ho ho...(devilish laugh)...A very cool idea, i might have to make my own version if i ever get two free cell phones.
