If you just want to do some fun stuff with LEDs you can get some color changing ones and some coin batteries and and do all sorts of fun shit for really cheap. 100 color changing LEDs cost about $25 and the batteries are about .25 each. They last about three days constantly running.
I don't understand what the point of these are.. Are you suppose to leave this on permanently or is it like..."hey check this out it...this toy...blinks?"
Heh, I completely agree. I really don't get it too. I promptly removed the LED from my Cure Hedo when I got it.
Did all of the Cure Hedo's come with the lights? I only have it in my blue, but my SDCC pink does not.
