The plastic horse I bought yesterday was too big to take a good picture, but here is a shot showing things warts and all.
The detector is on the left, the green glow is a cute little surface mount LED which show me when I am getting a good signal from the IR LED.
the IR LED is on the right.
The horse is filled with glowing goodness from the great life he led making some little kid happy.
Never mind the wires. Nothing to see there. Please move on.
