New trick for S2?
I do not own a S2, but i thought this might be neat to try. Glow markers can be had pretty cheap, and should fit in the S2, as a normal marker would (don't quote me on that ). There are also invisible ink pens that should work also. The idea is, that the S2 would make a path with the glow marker, and a UV led and photoresistor mounted at the front of the S2 would make the line follower sensor. The UV led would illuminate the glow track, and the photoresistor would be the light sensor for the line follower. This would enable the S2 to see in the dark. Not tested, but if anyone wants to try, the parts are low cost.
As a side note, according to some info, UV leds could be bad for the eyes. In my opinion, any led is bad for the eyes, if looking directly at them from a close range.
