I apologize for having sent the following with extra line-feeds in it;
Here it is again:
The main problem I see is with how you label the voltages at various
points in the circuit. If you have a 12 V battery, the low voltage end
is usually called zero volts and the high voltage end is called +12
volts (although the numbers are just relative to each other). You show
-12 V at one end and +12 V at the other, which you could only get with a
24 V source (which wouldn't be appropriate). Perhaps the following
would make more sense:
+12V +---------------+
+--------------------------------------------| Handy Board +------+
| +----+-----+----+ |
| +---------------------+ + 9V | | |
+------+--| Diode String |----------------+ | | |
| | +---------------------+ | + | |- |
| + | +---------------------+ + 5V | +----+-----+----+ |
+---+---+ +--| Diode String |--------------+ | | R/C DC Motors | |
| 12V | +---------------------+ | | +---------------+ |
|Battery| | | |
| 04A | | | +---------------+ |
+---+---+ | +--| Video Camera |------+
| | | +---------------+ |
| 0V | | +---------------+ |
+------+-----------------------------------+ | +--| Video Transm |------+
| | | +---------------+ |
----- | | +---------------+ |
--- Ground | +----| R/C Servos |------+
- | +---------------+ |
+-------------------------------+
