Mini Amp out of PSOne speakers.

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Mini Amp out of PSOne speakers.

Post by csurban » Wed Aug 06, 2008 1:46 pm

I'm not sure if this is the right forum for this but here goes...
I have two PSOne Screen speakers which i would like to just use as a simple AUX-in amplifier. I hooked it all up and tried it out with my iPod but the output was just too small for the speakers. (The 8 ohm impendence can't compete with the hundreds from headphones. :)) So I decided to turn it into a full fledged battery powered amp. Does anyone have any suggestions of a good audio amp circuit? Remember I don't need a potentameter because the iPod acts as one. I was looking at these free samples as an idea.

Can anyone who understands this more then I do give me some input on this?
nope... can't think of anything I could possibly want to put in my Signature Block...

Get a cheap pair of computer or MP3 speakers which run off batteries; open up; they contain an amp fit for purpose.
