This step is mostly measure, drill and glue.

I used a piece of black sheet metal cut out of a garbage can to be the back plate for all the bits, and then mounted it with two bolts. The whole thing is snug enough that two bolts is enough.

The capacitor should have 3 LEDs in each "arm", and to make them appear to pulse inwards you can cleverly arrange the LED chain in the back so they pulse in unison towards the center. It depends on the LED controller you have, but as long as they pulse in one direction, it will work, you just need to arrange them properly.

The two fluxing arms at the top of the Y are at an angle of 130 degrees in relation to each other. I spaced the LED holes about 1 1/4" apart. See Rooks page for an extremely nerdy over-analysis of this.

First you mount the motors, then insert the LEDs, then attatch the flux "arms"(drilled beforehand), and finally you glue on the orange and yellow wires (assembled beforehand).

Everything else is documented in the pictures below.

Awesome article! A friend and myself built one a while back for a Mythbusters/BTTF spoof: http://www.youtube.com/watch?v=OMUE5fKhzxA#GU5U2spHI_4

There's a fast-motion segment of the assembly in there. We used an old Makita tool box for ours.

We had very little time to build it, so it's not as authentic. It'd be great to know how you wired the LEDs and diodes, even as absurdly simple as it must be.
