amp for n64p

Post by MarioOwnsAll » Sat Jul 31, 2010 4:51 am

I'm going to be using a 3.5" lcd for my next portable and I heard that you need to build an amp to control the volume of the speakers. Is there a thread some where to build an amp?

This one I built is really simple and works quite well.
All you need are:
10k potentiometer
220 uf 16v capacitor (I used a 35v, works really well)
0.1 uf ceramic cap
LM386 IC
Some wire

And wire it up like so:

Ok from what I gather the potentiometer controls the volume, are there any meters out there that use two tack switches to control the volume rather then a dial?

EDIT: I am also using a 7.4v 5000mah battery, should that effect the components I use for the amp?
