Off-world Power Generation Lab 1: Free Space 1W Transmission

Use a full-sized solar panel to power a large battery
Use the large battery to power a raspberry pi through a voltage regulator that reports available power.
Use the large battery to power a small laser.
Add an on/off switch to the laser circuit that is controlled by the pi.
Point the laser at a small solar panel.
Power a small battery with the small solar panel.
Use the small battery to power an arduino through a voltage regulator that reports the available power.

Remember: we regulate the voltage, everywhere. Only voltage can force current where it is not wanted.

Can we keep the arduino powered 24/7?
