Here's my 1st attempt to getting the dome going.
I used the 12 ch. Remote from Ebay to turn on the lights and it will also tie into the Vex to control the periscope and other items in the dome.
When I press button #1 - I can turn the PSI's on/off , Press button #2 - turns the small logics on/off , Press button #3 - triggers the Builders Club display , Press button #4 - turns Holo on/off.
And I still have more options. Once I get everything figured out, I'll disconnect the little beeping speaker on the 12 ch.
