Hi, I am aware there are self-illuminating energon cubes on unicron.com, and perhaps another fan made kit available, but I'm going to take a crack at making my own. Does anyone have any advice? As a starting point, I'll need transparent or translucent cubes no larger than 2 inches / 3 cm square. Ideally, they'd be able to pop open easily to switch the light on and off. To that point, I'll need tiny light bulbs with a power source. Watch batteries? Finally, some paint on the inside of the cubes, although maybe some pink or purple plastic light filters would work... actually, maybe I won't even need the plastic and I could just use stiff light filters folded into cubes... Anyway, I wondered if anyone else has tried this and if they had any luck. Also, any advice would be great. If the project is successful, I'll post the results. Has anyone ordered any energon cubes online? How do they look? Were they worth it? How do they "work?" Cheers.
