For those of you who enjoyed my recent blog post on Circuit Duals and Magnetic Circuits I have now compiled a version of it in PDF if you want to keep a local copy or have it for reading on on an e-reader. Feel free to distribute the link.

For those of you who are just now hearing about it the article describes the idea of Duality in math, how it applies to circuits, how to calculate duals for systems of equations, and a few examples of circuit duals. It also goes indepth on magnetic circuits as a dual of electric circuits. There is an interesting blurb at the end about how to extract energy from permanent magnets as well.
If you prefer the more colorful blog link instead, which will also be the only place I make corrections or update it most likely, the link for that is as follows:

@lnxw37a2 Ahh yea I noticed that problem on my phone too. The site used to render fine on phones but my recent tweaking of the CSS seems to have broken that. so I will need to fix it.
Is the PDF version any better?
@skells I was actually revisiting them thinking I might re-write them geared towards a journal article and see if i cant get some future version of this published in a journal, perhaps the IEEE. So yea, figured I'd reshare them while they are on my mind. Glad you are getting something out of it.
@freemo decided to get the soldering iron you recommended and cheap(ish) multimeter btw, reckon that'll do me for now
thanks again for the advice!
@skells The soldering iron is sooooo nice, you wont regret it. ITs probably the most important thing to have nice since soldering is hard enough in the best of conditions when you are new. Next purchase should be a cheap o-scope, but you wont need that until you start to try to understand circuits better, which obviously is secondary to building circuits.
Feel free to hit meup with questions as you progress, it can be a tough subject for many to get their heads around at first.
@freemo will do, I'll send a few snaps once I've got something decent together
@skells also once you start getting into harder to solder stuff, like small SMD, or really large connectors like ground planes, you might want to consider the different tips for the soldering iron which make a huge difference. For now the tips it comes with are fine though, just keep in mind you have that option.
@freemo thanks for sparing me the humiliation of having to ask for these links again haha
