So, I own a scooter now, and since the weather is turning nice again, I'm looking into what can be done about little things like it's depressingly inaccurate speedometer and it's complete lack of front mounted laser weaponry (economy's fading fast and lasers don't need to reload).

While considering that perhaps I could use an Arduino to control an LED array and get an accurate speedometer read (and maybe control laser intensity) I stumbled across this video.

I wouldn't want to be the guy having to solder all those connections, but it might be worth it.
