I made a pocket pi grrl - absolutely brilliant.
The hiss from the speaker got on my nerves though so I added a mute function which puts the speaker into shutdown.

I've added a battery monitor so an icon appears in the top left of the screen to let you know you are running our of juice.

hey can you make me one of those please cause i really want one and i really want to try to make one my self but i can't afford it cause i'm 15 so can you help me out?
I didn't like that you didnt know the battery was running out so I've modded the PiGRRL so a low battery icon appears on the screen.
Wow, thats great! Thank you for sharing, much appreciated!
Nice build - an innovative solution - although I can't say I had the hissing problem you described. Instead, my sound quality was quite low, to the point where I thought I had a defective speaker which I ended up replacing.
The sound on mine sounds very low quality - like it's being clipped or reproduced at a lower sampling rate (like < 11khz).
This combined with your problem makes me wonder if that amplifier board is any good.
I dont have the problem with sound being clipped, I suppose some of that could be down to the emulator rather than the way it is amplified.
I wonder if you are getting distortion? Perhaps try adjusting the volume on the Pi (using alsamixer) up and turning the amp down using the pot on the board?
