At school we can do optional homework from a list. I made a circuit that uses green energy.

My Dad helped me.

Here are the pictures.

Geek notes from Dad:

• Solar panel outputs 6v at 330 milliamps in direct sunlight.
• The digital voltmeter measures the Solar Panel voltage output, the volt meter is powered by the Solar Panel and draws around 10 milliamps itself. The digital volt meter can measure between 2.5v and 30v.
• The 5 coloured LEDs when lit use around 70 milliamps of power.
• The battery pack can power the LEDs for around 140 hours without recharging.
• The battery pack takes 24 hours of sunlight to recharge.
• The solar panel can power the LEDs and charge the battery pack at the same time, though recharge time is increased.
• The diode is a 1N5817 and is in the circuit to stop the battery pack from discharging into the Solar Panel.
• Assembly is fine for a child with supervision.
• Hot glue gun is a saviour, the only person to burn themselves on it was me (Dad).
