I d like to demonstrate the pen i upgraded which has a left-right clik on board and which the pointer is visible all the time. The only disantvantage is that it is wired but i think it is not a big deal.

This can be built easy using an old mouse and making some soldering.
I find it really functional and practical for cad and drawing applications.
You can find the connections diagram on the whiteboard section.

Comments are always welcome.
