The title stems from the fact that this revision added wireless functionality. This is the first money spent on this project. A $7 remote control toy car was purchased and torn down for its precious wireless ICs.

Basically the parts from the RC car replaced the CAT5 cable. The transmitter was jammed inside the DPDT switch controller, and the receiver was attached to the SSRs. This was easy to accomplish. The following is the controller from a newer revision, the only difference is that the right switch is turned 90 Degrees

The power for the RC car was designed to use 3 AA batteries. Close enough that 5 volts won't fry it. In comes the 7805 regulator to power it. The motor ICs on the original car were more than enough to power the SSRs. Thus creating revision two. It is basically the same schematic as revision 1 so I will not be redrawing it. The following is the control board installed in the car.
