Hi!

Here is my handy Two-Button-Pen:




(To get a feeling for the size a standard AA battery is also on the image.)

It has a standard momentary-switch and a tip-switch operating parallel, so that I either can use the finger-button or press the LED against a screen/wall/etc. .

The power supply is a standard AA battery inside the pen - it can be changed very easily.

The parts you can see on the image are these:
1x SANFORD permanent marker (it was busted a bit and the battery fitted inside so well)
1x this ir-LED (more product information can be found here)
2x this button-switch (more product information can be found here)

I'm very satisfied with this pen.

If anyone wants more information on how to build it like that or how to install a parallel circuit, feel free to ask.

Perhaps I find the time to make a more detailed instruction, if wanted.

Cheers,

Spin

Good idea. I would love to use it, but I rear project onto a sheet so I can't apply preasure.

Hmm...
Some kind of plexiglass should do the job instead of a sheet of paper.

That's also what they suggest on this page:

Here's an even better description:

Don't get me wrong - I love my wiimote whiteboard. But if I had a rear projector I would probably try to build one of these things instead of using the wiimote.

Hey!

Hi!

Here is my handy Two-Button-Pen

What do you mean by two buttons? do you manage to receive right and left click?

No, I mean I can either use the finger button or use the button installed below the LED (meaning that I can press my pen on the screen to produce a click).

But there is already a software solution for right clicks on linux.
If you do a click longer than 0.7 seconds, it's interpreted as a right click.
Works great.
Check it out here.
