Sun Three Button RGB Light Doodler Mouse.

I meet Lori Stotko and Stuart Nafey http://lightdoodles.com/ at this years Makers Faire Auditions.
They had these cool Light pens they had made to doodle with.
I decided to make some when I got home, and remembered the old Sun three buttoned mouse I had saved in my parts bin .

Here is the mouse, I had removed the cable years back for so other project.

Here is the mouse opened and the three buttons I will use.

I decided to remove all unneeded hardware to make room for the battery holders.I also added a ground wire for the batteries.

I am using two 2032 battery holders for power.

From my parts bin of old computer and electronic parts I found a 6 wire pin cable to connect the 3 LEDs to the switches .

The six wire connector was soldered to the three switches and a common ground.

Here is the board after soldering ready to test.

Now to see if it fits back in the casing.

Using the red LED that was in the mouse and adding the green and a blue I fired it up.
Success !

During the same build I made a remote for my Canon so I would not shake the camera while exposing the shot.

Make the room dark, (I waited for night) push the remote shutter, draw!
I found the Blue and Red were really over powered the green, perhaps I will put a pair of resistors
on those.also I could buy a RGB led with all the emitters in one , but this was made with parts "mined" for old Tech waste.
