Charge your phone with the wind!
In his words, "I go very often to cycle in the nature where is no electricity, and during a long bike tour my phone usually discharges. These smartphones have a large capacity but its consumption is big too. I made a few weeks ago another bike turbine for the Bicycle Contest, but I think I can make a better one. So created an all in one wind turbine power bank"

The turbine shown mounted

• an old CPU fan
• toroidal inductor
• 2N2222 or 2N3904 or BC547 transistor
• 5v step-up module, (boought on eBay)
• germanioum diodes (5 pieces)
• a small perfboard
• an old phone battery or a 18650 cell
• and a small switch
• bike support element
