A very common diode for this circuit is the 1N4001, rated at
1 amp and 50 volts. The 1N400x series are all rated at 1 amp,
with the last number increasing with higher voltage ratings.
Thus, a higher rating, such as 1N4007 will work just fine.
Bringing it all together
Okay, we now have each module designed. We need a switch
to disconnect the battery from the camera, to keep the camera
from discharging the battery when no track voltage is present.
Bringing this all together, we get the complete circuit diagram.
