Using the instructions available I made my push-button IR-pen. As a push-button a small keyboard button was used. Very nice, however there was a need to constantly remember when to push and most importantly when not to push the button. It works great, but not a real white board experience.
Like some others the idea came up to build an IR-pen that when pushed against the white board for writing will turn on the IR and will turn the IR off when the pressure is released.

Hopefully soon I will have the time to build and record the building of the push-tip IR-pen.
