There's still some interest in this from fb. Mine's been working well since the project. No flickers or strange things.

The guy that did these crashed his car and left the 3800 scene probably later in 2017, when this was last updated.

I wouldn't suggest trying to make any money on them these days. Clusters are cheap at 20 bucks a pop on any junkyard.

You could try this yourself like 4 times for under $75. (3 at the yard + 1 in your car + LEDs, etc)

That's all I got.
