| 1. We create the frame of the turbine by using scrap wood pieces |
 |
| 2. We cut the plastic bottles in 2 semi-circular blades |
 |
| 3. We connected the turbine axel with the wood lamina |
 |
| 4. We took 4 magnets from an old HDD, that would normally have been thrown away |
 |
| 5. We attached the magnets on the lower part of the inferior wood lamina |
 |
| 6. After that, we’ve made 8 induction coil from a plastic ring (the bottle neck) on which we reeled copper wire |
 |
| 7. We glued the coils on the wood platform, under the lower wood lamina |
 |
| 8. We connected the lamina, with the platform and the axel |
 |
| 9. We connected the wire from the coils one to another and with a LED. |
 |
| 10. We measured the voltage produced - about 8 V |
 |
| 11. We measured the frequency of the AC with an oscilloscope |
