 The Silverlit Spy Cam Aqua (Sub-112) is a small toy submarine with infrared remote control and onboard video camera.

 Also sold as "EXost" "X AquaSpy", brand "Tooarts".  There also appears to be a similar (later?) model labeled "Submarine 3046", "Cam Project-T", that has a steerable rudder and different remote controller.

-====== Hardware Description ======
+===== Hardware description =====
 The submarine contains 3 motors - left and right side propulsion motors, and a dive/surface motor.  There is a forward-facing camera and two white LED illumination lamps.  On the top there is a power switch, red/green status light, and an infrared receiver.  Both electronics and motors are powered by a single pair of 1.5V AA cells.

-=====Remote Control=====
+==== Remote control ====
 The remote runs off 4 x 1.5V AA cells.  It has 7 controls that signal the submarine using 2 infrared LEDs :

@@ Line 113: / Line 114: @@
 The remote communicates using bursts of a 38kHz carrier, infrared, signal.  The signal is encoded using pulse length modulation (PWM).
-===== Batteries =====
+==== Batteries ====
 In freshwater, using Alkaline batteries, the submarine floats with just the status light dome above water level, in saltwater it floats slightly higher.   Carbon Zinc, Alkaline, Lithium and rechargeable nickel-metal-hydride batteries all weigh different amounts.   Rechargeable nickel-metal-hydride weigh the most, and the submarine just sinks to the bottom as they are too heavy.

-====== Operation ======
+===== Operation =====
 The two propulsion motors are driven together to give forward or reverse motion.  Varying the relative speed of those left and right side motors is used to turn the craft.  There is also a trim adjustment to account for differences in the left/right side propulsion.

 When using the dive propeller to surface, the two side propellers turn on as well.

 Because the communication between the submarine and remote control is via infrared, the remote needs to be pointed towards the submarine, and the range is severely reduced in bright sunlight.
