SlideShow Software

I think I put together this :

Simple audio enhancement

By using gpio pins 12 and 13 with a slightly modified

improved .

Re: Best performance sans heatsinks ?

That is a nifty looking heatsink.
I'll just leave mine as is.
One of the first things I admired about
the RPi's is the ability to run without
a sink. (compared to comparable Intel types)

Re: Best performance sans heatsinks ?

Thank You !
I got one of those cases for my wife's Pi.
(modified to put the SDC on top in front)
It is still slightly awkward to change.
O.K. for hers, but since I constantly change
mine I prefer bare.
