new project - SRV-1 controller on an R/C tank base

Started surgery today, removing the existing R/C controller and sorting out the various signals. The interface task is pretty simple - there are two drive motors for tank tracks, and those will connect directly to the existing 2-channel PWM output from the SRV-1 controller. ¬ †Those are the red and while wire pairs shown in this first photo. ¬ †The other red, blue and black wires lead to the battery pack and power switch.

The gun turret interface will take a bit more work. †On the left (black and white wires) is the turret pivot, and it's bidirectional, so we'll probably just build a simple h-bridge or else hook up a small relay to control this.

The small black wire coming up through the turret connects to the radio antenna, and the larger assembly in the middle of the spocket is the airsoft gun with a tilt mechanism. The tilt mechanism is a simple cam, so the motor only operates in one direction. The red wire into the gun assembly is grounded, and if the black wire gets +voltage, the tilt cam starts to operate. If the black and white wire get +voltage, the firing mechanism is activated. So we just need to use 4 bits of digital output to control the turret swivel, the turret tilt, and the gun trigger.
