The LEDs are current limited with 10K resistors, why so high? This makes them barely visible, if at all. The right thing to do is put low value resistors for full-brightness 20ma, then if you want dim or off, this can be done in software (PWM).

I compromised with 1K, which is 2-3ma (depending on LED).

They are a bit dim when in the case, in a hurry to fullfill the kickstarter I didn't revisit that.
