quick video demo there as well. irony is that in fixing the dynamic
range (200k - 2.4k resistor bridge) i might have found out what the
problem with the PWM circuit was as well: overload of theTDA2822D.
however, after putting the scope on the output from PWM even after
quite a lot of RC filters i really don't want to chance it. 12-bit
DAC on an 8mm x 18mm 0.5 watt speaker is... enough :)
