How to DIY simple wind charger so that we can ride and charge mobile phone

As we know,smartphones cost more in electricity.And nowadays people become more and more reliant on the mobile phone. Besides, they will have the feeling of nothing left to live for. So it is normal that people need to charge for their mobile phone from time to time. However, it is not easy to charge everywhere especially when you don’t take portable mobile power.Now a 16-year-old boy Thomas makes a simple wind charger assembling in the bike. It only costs him 5 dollars. Now he can charge for his smartphone when riding. Let’s see, how does he do that.

What the necessary tools are: soldering iron, glue gun and wire tape.

What the necessary materials are: an old CPU fan, a ring inductance coil, 2N2222 or 2N3904 or BC547 transistor, 5V boost module, five germanium diodes (Bought form Kynix semiconductor), small circuit board, old mobile phone battery and the bicycle fixator.

Then, it is the work by electrician and hand. First, disassemble the fan and find the leading wire to connect together and use the electronic gauge to check which wire lead is the highest and remove another leading wire. After that, connect the germanium diode and the circuit board to build the electricity bridge. At last, fix the lithium battery and circuit under the fan and then install in the bicycle. Of course, the premise is to connect the cellphone to check whether it can charge or not and then fix in the bicycle.

The speed of the simple charger cannot be comparable with the standard recharges. It only can be used in the urgent emergency and hope it can do help to you guys.
