Now i will go on modding the mouse case and forget the electricity for a while.

I thought about a glowpad too so i need power directly from the power-supply anyway so I will connect the mouse to that glowpad for a while (with an extra cable) just to have it running.

Well I think it depends on what pins you use.
I have a USB logitech which is not optical.
After installing it and opening it I see a 1.6 V between the incoming red and white wire, but attaching a normal red LED gives a very very faint signal, definitely not 20 mA ?
The only way I can make a LED shine is by using the same red wire but with a black connector instead of white. This has a 4.8V connection, so if I computed correctly : I use a 330 and 470 ohm resistor in parallel, this gives me 193 ohm plus a drop of 1.6 V from the LED, that is about 16 mA, I think :) (I'm a n00b).. anyway the LED shines reasonably bright now.
Oh btw I also don't know how to find out if some pins will be able to deliver current other than try it.. I also thought I could hook up simply the amp meter.. but I think I fried it :\ shows meh skillz :)

oh btw respect to the site ! as soon as I got the stupid LED business figured out I start windowing and finding a LEGO :D \o/
