My SAIT Final Project: "Very
different than a power supply".
The basic idea behind this is that the large solar panel array is
used to trickle charge a 12V 12AH sealed lead acid battery, the
battery then powers a 300W power inverter. That way the solar array is always being aligned towards the brightest
source of light (usually being the sun). This will effectively double the power output of the solar array. The two smaller cells to the side
are what power the circuitry and motors. Once the light source is centered
the motor driver is powered down and a pair of ultra bright LEDs start to
flash (one for the X axis and one for the Y axis).
For demonstration purposes it
can also be battery powered with the flip of a switch.
Inverter box with battery:
7.623Kg (16.8 lb)
inverter box: 8.862Kg (19.537 lb)
Combined weight: 16.485Kg (36.34 lb)
Head measures 2 feet tall by 21 inches long at 19.5 inches wide
The last pic here is of the bottom side of the PCB, I tried to put all
sorts of hidden things like that.
