Help My psp battery and my lm386 mod!
« on: December 30, 2009, 08:57:51 AM »
I just recentLy made my duaL eLastic nub.. it worked perfectly but the analog is rough itseLf..

During the making, i turn my psp to test.. after testing, i removed the battery w/o shutting the psp off..

i was nervous and scared if i burned my mobo, but thanks that the battery is the probLem..

Can i restore my battery in any way?.. :beg:

2nd question.. after doing my dual nub.. i tried to on my sound reactive leds.. i tried to play  music but it suddenly shuts off when a loud part is pLaying.. but if you lower the volume it wont shut off..

what couLd be the probleM?..

here is my duaL nub..
psp DUAL NUB mod

notice why i didnt turn on the volume because it will shut off immedietly..

Boooh Yah!

Sounds like its drawing to much power to were it overloads and shuts off. I cant be positive though so lets see what others say. Nice nub by the way.

That happened to me before when if you raise the volume too high it shuts off. What i did was take out the LM386 and put in a 2n2222 transistor. Works fine and is alot more sound reactive. :D
