This shows the guts of the Vex Remote.
My idea is to add to the 1 remote an extra transmitter (it's the big brown board).
I will add a switch to control which board will transmit the signal at any given time.
In Essenes this will leave me with a 12ch remote that I can use to connect to 2 different Vex micros on different Freqs.
I'll use some controls to drive the body, dome, arms, doors. Then flip the switch and I can control the periscope, pie panels, etc.
Since I have incorporated the 12ch Ebay remote to the Vex micro, This gives me additional channels to control things like the lights, holo movement, etc.
Now I have more than enough channels, 16 motor ports, and I/O ports to work with, I'm not worried anymore about controls.
