How to Use a Solar Calculator to Power an LED Bulb
- 1). Turn your calculator on its face and unscrew all visible screws.
- 2). Lift the back and front panels off the calculator to expose the internal circuitry.
- 3). Locate the solar panel and its lead wires. Snip the solar panel's lead wires as far away from the solar panel as possible, and remove it from the calculator.
- 4). Strip the ends of the solar panel's wires and wrap them tightly around the leads of the LED bulb. If it doesn't light up, try switching the connections.
