Copyright (C) 2010 by Michal Zalewski <lcamtuf@coredump.cx> There are quite a few primers on electronics on the Internet; sadly, almost all of the top hits resort to gross oversimplifications (e.g., hydraulic analogies), or convenient omission, when covering subtle but incredibly important topics such as the real-world behavior of semiconductors.
There are some exceptions, to be sure - but they tend to suffer from another malady: regressions into mundane, academic rigor, complete with differential equations and complex number algebra in transient analysis - a trait that is highly unlikely to be accessible, or even useful, to hobbyists. The physics of conduction [link] As you probably recall from your school years, the dated but still useful Bohr model of the atom explains that atoms consist of a dense center (nucleus) with a variable number of protons and neutrons.
The strongly bound and heavy nuclei of stable isotopes do not undergo any structural changes under everyday circumstances. Hardware/Electronics/Hacking/DIY/Etc.
