Ok, I just posted 4 new videos of the TRILLSAT-1 prototype over at my #TrillSat project page, and one of them demonstrates this tethered haptic Morse code system in operation (shown below).  In the demonstration, I set the haptic passcode lock, unlocked it, and then sent a command to turn on the wireless Qi charger via the two-way haptic system.  I also show the effect of acceleration due to gravity when the craft tilts for its solar tracking function.  I hope these videos give you a better feel for the project.
