Has anyone successfully hacked a 12 button traveler to output other info? All of them that I have are not functional so I did a little reading. It sounds like it would be a huge job for me, but it should be possible to control the 14 segment display on them with an Arduino or equivalent. I think it would be astounding to have one display the 5v WBO2 output and the 5V boost output. Heck, even if it just displayed the raw voltage, I could learn to work with those units.
