No IDEX updates, it’s on the list… 
Have been distracted with working on wrapping up, and starting 
, other projects like playing Tetris on a Wood tiled display (192 servos, Raspberry Pi). The display doesn’t set fire or smoke anymore, so hoping to get back to this one soon.
Next step for my IDEX is wiring up…
Going with more involved relay setup, for control, and compactness. Fastest design-assembly option would be something like this.
