Heat up a small pool with this solar-powered system

Imgurian “ElectricYFronts” has created an Arduino-controlled solar heating system for his kids’ paddling pool. Small semi-portable above ground pools can be fun, but are generally not heated. The “Solar Paddle” system, however, raises the temperature of the pool from a chilly 68 degrees Fahrenheit to a much warmer 83 degrees (20 to 28 Celsius). It does this by piping water into […]
