==Additional Hardware==
The software follows a LED pointer, which could be made depending on the user preferences and mounted on the extremity that the user choose. Hence, the additional hardware could be built in many ways, being the prerequisite the light must be white, and preferably, to get optimum results, with high luminosity.
In the next, as an example of the possibles ways to make the device, it is presented a headband to mount a LED in the user head.
===Materials===
====For the light====
[[File:Vincha hMouse.jpg|thumb|right|300px|The head band to mount the LED. Notice that it used to be headphones.]]
*High luminosity white LED
*Headphones, headband kind
*3 AA Batteries
*Switch to power on and off
*PVC pipe
*Copper wire
*Tin solder
====For the filter====
*Floppy disc (3 1/2"")
====For the click====
*Adapted mouse
*Button to the adapted mouse
===Headband===
To secure the LED to the user's head use a headband headphone. In the rear of the headphone is attached the battery along with the switch; it could be used silicon or another kind of glue. To on extremes of the headphone is mounted the PVC pipe. This pipe will serve two functions: it will contain the wires to the LED and in its end will be mounted the LED, and also, as the pipe is flexible, it will allow adjust the LED direction with ease.
In the end of the pipe, the LED is pasted with glue. Now you can make the connections with wire, from the batteries to the switch and from the switch to the LED.
===Filter===

[[File:Filtro.jpg|thumb|right|200px|Lo recortamos para que no tape la pantalla.]]
For optimum functionality in any light condition, it's possible use a physical filter for the camera, to avoid the ambient light and only the LED light will be visible to the camera.
To build the filter could be used the soft disc from the interior of a floppy disc. Because the intention is attach it to the XO camera, it must be cut to avoid the obstruction of the screen. To mount it we simply use the metallic center, putting it in the speaker it remains pasted by magnetism. If the disc is too much dark, it could be brightened with alcohol or another solvent.
===Click===
A click by software is not implemented yet, so is necessary do the click using hardware.
To make the click you could use an adapted mouse<ref>http://www.youtube.com/watch?v=jCOzx5211Xg</ref> and add it a button. In time to choose the button you must consider the user capacities and preferences. In the picture can be observed a button by blowing.
