How to miniturize a wireless keyboard? Answered

There is a certain individual who I enjoy playing practical jokes on. I came up with a pretty good one but I am not sure how to pull it off. Here is what I want to do. I want to connect a wirelless keyboard to this persons computer in addition to the wired keyboard already on it. Then when this person uses their computer I can sit in the corner and type on their computer and flash the caps scroll and num lock lights. The problem is that I can't hide a full size wirelless keyboard. So I need to either make or get a miniature wirelless keyboard. I also don't want to spend to much money on this since it is just a practical joke.

Thanks.

Break out the driver board as above - you will need 6 micro switches and a micro controller to decode them .

This instructable will give you a good starting point.

Just like in the instructable take your keyboard apart. Find the buttons you want to use. Map the traces in the membrane back to the main controller board. Then you can take that controller board out of the keyboard, add a battery pack and solder in push buttons to the pins you mapped out and place everything in an enclosure. Then you can sit in your corner with a little box in your have playing with Caps Lock, Number Lock and whatever else you want.

You could also add a wireless mouse to his system and play around with the pointer. That would be much easier to do. And yes you can have more then 1 mouse plugged into a PC at once and controlling things.
