In a world where generators can cost thousands or even tens of thousands of dollars, Jake von Slatt has come up with a clever solution using an old car. By converting a Toyota Sienna minivan into a powerful generator, von Slatt is able to save money while still enjoying off-grid power. He utilizes the engine and alternator from the car, along with an Arduino Nano Every board and an H-bridge, to maintain a steady 60Hz frequency. The Arduino monitors the alternator output and adjusts the engine speed accordingly. This simple yet effective solution keeps both the car and the generator from ending up in the scrap yard.
