The idea was to give one cube control of the light that glows in the other one.
The circuit was split between the two cubes. One would contain the microcontroller and the leds, while the other would contain the battery to power the circuit.
I used the glass I found in the projector last week to disperse the light.
Current Status: I got the circuit working and went about sticking the sides together, but then ran into some issues with loose connections or grounding. Unfortunately, I tried for a long time, but wasn't able to debug it.
I made the plastic box to complete the circuit, but didn't have the time to mount it.
Looking forward to finishing it up.
