After getting the Tux mouse for my birthday from the children, I decided to have a go at modding it. It is ideal for a LED mod as the back part is clear plastic. The first thing to do is dismantle it :o. So here is one dismantled mouse:-
The next thing to do is findout which pins from the PS2 connector go to where. We must now look for the 5v and ground.
With my trusty Volt meter found that on my mouse pin 4 is the blue wire and pin 3 is the green wire.
All I now need to to is wire a LED in parallel and it should light. Note the 2 wires running across the PCB. I would recommend using the very thin wire you have as the space can be very tight!
The last thing to do is make a hole so that the LED can light the penguin in his liquid filled home.
And this is what it looks like :-
One thing you can't see in the pictures is that the LED is wired up in series with a 100 Ohm resistor, as the LED cannot cope with the 5 volt supply.
I think that TUX is much happier in his lit home - project 4 finished :)
