One of the hardest simple things about electronics is soldering. I had a EE professor once say that soldering was "impossibly easy" which, only those who have tried to figure it out on their own, have come to understand the meaning of this description. I have been trying (and mostly failing) to solder for years before I was sent the links below but, by the end of the first video, I could solder tenfold better than my best previous attempts. After the the second video, I was ready to take on the world.
