If anyone wants to tinker with a start button, I've got one that is taken apart. I'm 99% sure it still works. It would be good one to use as practice if you want to mod your own start button. Or mod this one and get it working and installed and then you can give away, sell, or keep your original one. The start/stop text on the button is sanded down and ready for painting, although I recommend you give it one more light sand and clean it with alcohol prior to painting - it's been sitting for a while. The circuit board is also good for practice if you want to try the LED color change.
I tried the LED color change, but those LEDs are too small for my fat a$$ fingers. It will take someone with more soldering skills than I have. And probably better equipment, too.
