Yes, in my studying of both the GP's the other day it was evident that the small GP was attached to an external VIC, as opposed to the big GP which had an internal VIC.
My plan is to use the Multi Bobbin VIC or a varied configuration thereof, to run the GP. (As I imagine Stan would have done)
However you still have to consider the proper pulsing of the LEDs, (which might be synchronized with the pulsing of the VIC in some form?)
I am thinking i'll test both Red LEDs and then some cheap UV LEDs (similar to yours), just make the LED Batteries easily removable so I can switch them.
