Hey, I'm trying to build a wireless link for a TI calculator (specifically a TI-84+ SE)...anyways if anyone has any information on such a transmitter, that'd be sweet. I can't find any schematics...Thanks!

 

Have you looked in on the TI site?

 

Yea, I've looked on the TI website, but no calculator-specific rf transmitters/recievers...

 

They might be concerned that such a link might make it possible to pass answers around during an exam.

 

Yea, that would be a concern...however I wanted to build this for multiplayer games. Any suggestions on how I would use a microcontroller for this?

 

So I figured out I would need to multiplex it in order to make it bidirectional, however I still need help. Really I need a very basic step by step approach so that I can learn how to assemble this. What basic materials would I need? Thanks to anyone that helps!
