How to make a simple IR-pen

We needed a few IR-pens to use with wiimote. So after a few reading I made some samples.

If you don't want to work with a soldering iron and a hot wax gun, you can always use a simple lighter with a LED lamp instead of an IR pen. If you prefer this just change the LED with an IR diode.

CAUTION: Be careful while using soldering iron and hot wax gun. Accidentally touching the hot parts may cause serious burns.

-Buy a simple flash light and dismount it.












-Use soldering iron to heat the metal part of the lamp and detach the glass part from the metal part.




















-Mount the IR-led to the place where you detached the glass part and solder it. Be careful about the poles of the IR-led. In standard leds, long leg is connected to the anode(+) of the battery.














-Cut the parts that you don't need. need.












-Just re-assemble it and your first IR-pen is ready.




Note that most of the flash lights use switches. If possible change the switch with a button.
