This is probably the single most over done, over blown, over budget (for a 'battery meter') project I've seen.. And simply the best!
More over-the-top than an 8x8x8 LED cube?!? 
Haven't considered an 'open kit'... probably not a large demand for Scooterputers. Thanks for the feedback nickvd!
Is the lean-indicator affected by centripetal force in curves?
The accelerometer is quite sensitive while riding. And for some reason it seems a bit more "bouncy" with the cell module plugged in. The Lean Gauge does register in the turns, but I'll need to dampen it some to take the jitters out. Really it's questionable how useful the lean indicator is on a scooter - just fun to play with the accelerometer. Thanks bill2009!
