Creating a Wireless Keyboard or Mouse

hey guys, i was looking about the internet to find a wireless keyboard and mouse to use while I am relaxing on my couch and it occured to me there has to be some way to hack a keyboard or mouse I already have to be wireless. I think RF is the best choice for at least the mouse (quicker speeds) but have no idea what to do or what to use. Help!

ah okay, i was hoping that transmitter/receiver pairs would be cheaper, it just hurts me inside a little to spend $120 on a mouse/keyboard. Thanks anyhow!
FM-based wireless headset systems can be had pretty cheap. Even at the local dollar store. Of course, sound quality is unimpressive with the el cheapo ones, and range is poor. But to fix the range, more power ought to work! They would probably be more than adequate for simple on/off transmissions.

Building an RF receiver and transmitter are no small feats for someone experienced in the field, but if you are not, this will not be an easy task, unless you plan on getting a transmitter/receiver pair and modding from there. That will be more expensive though. I have fiddled around having made a few AM receivers, and one small transmitter, and I personally couldn't see myself tackling the problems involved with what you have proposed. But then, you may have more ambition then I do, too :-) Good luck.

As far as I know, both keyboards and mice send binary signals. So build a "wireless telegraph", and it should be fine. The power pulse on the user end would send a pulse to the receiver end, and that would give a pulse to your computer just like there was a wire in between. I don't knwo how to build the "telegraph," but I do know that that's all it would really have to be, and that you could tap it into the in/out wires on your keyboard/mouse. Have a battery on the user end to provide power. Precisely where to put it would probably vary by model, butthere's only so many ways it can be done, trial and error looks promising. I think this would work a heck of a lot better for USB devices, and those can be had easy enough. Multiple pins would demand multiple discreet frequencies.
