The manual rotation of the crank is transformed by a gear into a fast spinning electrical generator, which powers a bright shining LED.
The kit is easy to assemble and only requires common tools. No soldering required.
Dimensions: approx. 18cm x 7cm x 7cm
You may do own experiments like loading a capacitor (to store energy) or charge a mobile phone. Necessary electronic parts are not included.
Suitable for makers above 10 years.
Warning: At high crank speed the light could be very bright. So don't look directly into the beam.
