A grab-bag of electronics circuits, theory recap, hacks and gear nostalgia.

Before you trust what is in here, please note that my skills are most
developed in the domains of software and general engineering/DSP math.
My understanding of electronics theory is reasonably up-to-date, but
from the practical design point I lack some experience.  These lab
notes mostly log the learning experience of designing some (analog)
electronic circuits.

See also notes about gEDA[1], notes about designing an analog
synthesizer[2], ARM microcontroller development[3] and some digital
electronics notes dispersed in the Staapl lab notes[4].
