Okay i am putting 14 to 16 lcds on my slim psp. the question i have is will the 5v point above the nub be fine or do i have to use another point. they will be
6 sound reactive and the rest not. and  if not were can i solder for another 5v point. and i do not want to use the hold or the wifi switch and add a 8 pin dip switch. were do i solder the negative point to to do this.


any one know were i can get 2 chot cam for 20 bucks each. i want to install one in the front and back using one of the switches on the dip switch to switch between and  one to turn off both.
