Backlighting a transparent powerbook trackball via GPIO or Berg power on a blue scsi

[iantm]

I'm dreaming big here, but it sounds fun…

So I picked up one of these translucent 30mm "contact juggling balls" that just so happen to fit and work perfectly in a Powerbook 1xx trackball:

Someone jokingly said "backlight it!"

And I thought — why not try?

But before I get to giddy about it:

• v1: Is it feasible to hook up a dumb series of LEDS to the berg power of the internal blue scsi to put some light behind it?
• v2: are there PWM GPIO pins available on a a powerbook BlueSCSI to provide any degree of software control over this?
  

Keep in mind — I know little to nothing at the moment. In my college days, I did manage to hack a device called an EZIO (basically an academic professor's precursor to the Arduino) to read the pulses of a rotary dial phone and respond with software. That was forever ago now. But I want to get back into stuff like that!

Anyone with pointers or corroboration that a solution is possible would be great

Umm, do you want it weird? you could hook it up to the x and y axis of the trackball so whenever you moved the trackball it flashed. Probably better to hook it straight to a 5/0v pin somewhere. But I don't know where that would be...

If I get to this pipe dream at all, the sky's the limit, I'll get weird! I'm not even sure if the PicoW bluescsi has a line for power available…

I think that is pretty cool. Translucent Fruit colors?
