Will try to build the Wii Remote Into my laptop with a flick-switch for on and off function on the thouchpen, and so the Wii Remote gets the power from the PSU instead of the batteries

@SuperFifamaniac Yes, that is me. shakespeare1212 is my ebay id. I can sell you ready made IR pens as well, and Smoothboard.

@Shakespeare1612 i went to ebay to buy the leds and i saw that the peerson who posted its name was shakespear1212 ....is that u?

Omg does this mean you can play Osu on the table with a pen???

[Shakespeare1612]

@SuperFifamaniac No, you can't use an invisible ink LED. Those LEDs are ultra-violet, not infra-red. You can use a candle flame, or an LED from an old TV remote. To go professional though, get a vishay 6400 IR LED from ebay. This is the exact model that was used in this video and Johny's other projects.

@Toto77777 There is a pen that activates from pressure on the tip, but you are correct in that there is currently no way to like make lines more heavy because you pressed down harder.

[Shakespeare1612]

@PackedUpReviews Get an IR pen too, and a USB bluetooth dongle, if you don't have bluetooth built into your computer.
