The Solar Science Station is a non-soldering solar USB charger. Use it as a tool for recording solar data in the classroom and as a power supply for gadgets. We've designed it around a large 5.5V 320mA solar cell that sits on a rotating axis (with degree measures), so you can adjust the angle. We have also engraved degree measures on the side. Record heaps of scientific data by having students measure the angle in degrees, the time of day, and the voltage output on the LED Voltmeter display!
The kit can be assembled with only a screw driver and wire stripper, which means it is 100% reusable. External rechargeable batteries are available add-ons (choose either a 2 AA or 3 AA battery holder) with a built in switch.
