I've played around with electronic things all my life yet the theoretical side of it has largely passed me by. I tend to fiddle with things until they work and regard the flashes and bangs of destroyed components as R&D costs.
Most things are variations on the same circuits and I've found I can do most things I want to with a few 'stock' ICs. LM317s are great for making or modifying power supplies and LM386s are good little amplifiers. They work out much cheaper, and are easier to use, than discrete transistors.
Circuits featured here haven't just been blindly copy and pasted from other web-sites: I've built them, possibly modified them and deemed them satisfactory.
