Touch sensor weirdness...
It's a wonder that these circuits work at all with the fractional pico farad involved. I built a self-capacitance one with Atmel's Q-Touch on a bog-standard mega329 (very similar...

allocating memory to an array of pointers doesn't work
A superfluous semi-colon if we're in pedantic mode. The missing cast although necessary to prevent a warning, shouldn't result in faulty code. (Casting is very important when de-...

Audio pitch down code debugging
I understood from the linked articles in #8 the "blending" is only a hack at suppresing the click as you jump from an old set of samples to a new set. Keep it simple - Just try...
