Yay! I’m not crazy (or visually dyslexic- which is huge being I do animation). I had mine apart when I first got it, as I was able to get it pretty cheap on eBay due to it being “broken”- which was a simple fix of one unsoldered wire. However the way they wired it is pretty messy - to swap the direction, you’d have to unsolder the lead power wires and a few other things if I remember correctly (it’s been a couple years since I had it apart), then put in longer wires so they could all be flipped and work.
However I’m kinda thinking about drilling a few more holes so there’s at least 6 LEDs per row, and running those off a timer with each LED tied together so they run in sync- at a given speed but not adjustable.
A cool trick would be an arduino tied to an accelerometer, that adjusts speed based on ones own actual driving speed. Anything under 70mph is “calm”, and anything over 70 would be “hyper” or a faster sequence.
