These plans detail how I built a wind turbine in my garage without any special tools for just over $200. Many of the do-it-yourself designs are either toy projects or unlikely to hold up in strong winds. This wind turbine will withstand 40+ mile per hour winds and produce electricity with as little ...
I was messing around with a power bank that I had when I noticed that it would be extremely easy to add a couple diodes to the end of this, and have it still be able to charge your electronics! Yes I know that they sell these, but I just wanted to experiment on what I could do with this. A little ba...
