I am probably the uber-est n00b when it comes to this kind of electronics stuff

I with you, this is just the product of a lot of research!

so I'm not quite sure what to do. I thought I'd try out this wiimote whiteboard thing just to learn something and have a little fun at the same time I have bought some Vishay TSAL 6400 LED's so far... and I have no idea what to do. I did not buy resistors because I'm not sure what to get.

I understand that the LED's forward voltage is 1.35v and a max voltage of 1.6v? So if the voltage of a battery is 1.5v will it work without any resistors?

Keep it simple:

IR-LED to switch to 1x 1.2v Rechargeable AAA back to IR-LED

Only requires a few solders, the IR-LED is a little underpowered but I don't seam to have any problems and no need for a resistor so two less solders to mess up.

I managed to fit all this in a 'Artline' permanent marker confiscated from one of my lovely students!

I'm sorry for asking what are probably some really stupid questions but I would love to get this working.

I appreciate anyone that takes the time to answer me

No such thing as a stupid question!I appreciate anyone that takes the time to answer me

Good Luck
