How to Make a Dynamo?
Apparently, it is easier than I thought to make a very small power generator for your easy to charge electronic devices, like a phone, for example. I was wondering how difficult it might be to fabricate, DIY as they say, my own charger that could work on footfall or leg movement, to charge my cell phone while I walked to the store or to the library. My first search turned up some advice to just cannibalize an existing electrical motor from some electric device, which might work if there were a junk yard near enough, but you’d still need the other materials, apart from the actual knowledge of how to do this. So, how much knowledge is actually required? Well, there are quite a few videos up on YouTube, of course, but whether those are reputable and actually work without burning down your apartment, I cannot yet say. Let’s look at the basic science of the problem, first. Project Do Better mentions this matter several times, as I recall, or hope, since it has been a while since I wrote it, and I know that this idea was on my mind all of that time, but then the (always free…) Do Better manifesto is an organizing manual, not a science textbook, and I remember cutting out a good bit of material in the final few drafts. So, I did some searching.
