Astable Multivibrator: Dressed-up LED Spider

Adding a bit of trim to the bottom of the LED spider makes it look better and helps keep the strut wires in place:

It’s obviously impossible to build like that, so it’s split across the middle of the strut:

Glue it together with black adhesive and a couple of clamps:

The aluminum fixtures (jigs?) are epoxied around snippets of strut wire aligning the spider parts:

Those grossly oversized holes came pre-drilled in an otherwise suitable aluminum rod from the Little Tray o’ Cutoffs. I faced off the ends, chopped the rod in two, recessed the new ends, and declared victory. Might need better ones at some point, but they’ll do for now.

Next step: wire up an astable with a yellow LED to go with the green and blue boosted LEDs.
