Sound reactive LEDs with a single transistor
IntroductionHello fellow Acidmodders, This is my first tutorial ever its for my latest mod sound reactive LEDs with a single added component, its a 2n2222 transistor. I decided to figure out a new way to do this mod because when you apply the LM386 to a Slim psp the LEDs are very brightly on even with no sound and they don't react to the sound as much as we are are used to from the same set up on a phat PSP.
Parts Needed 1. 2n2222 transistor
2. LEDs
3. Switch
Tools Needed 1. Screw driver
2. Soldering iron
3. Knyar wire
Difficulty rating: 1/5
Not too difficult if you have done a sound mod before its not much different.
Average Time to Complete:1 hour
Notes: If you are using 2.6v Red LEDs you may need to use a 100ohm resistor between the power from mobo to the LED.
Step By Step Tutorial1. Open up your PSP and remove the mother board
2. Refer to L0rdnic0's tut on installation of the sound board here
https://www.acidmods.com/forum/index.php?topic=20226.0 for positive and negative points for speaker and power for LEDs.
3.
Wire your transistor as depicted and route wires as a normal sound mod.
4. Close up your PSP be sure to test before you do to avoid striping screws.

FAQ/ TroubleshootingIf your LEDs do not turn on with sound check that your power switch is on for the LEDs or it may be a short in your wiring test the LEDs with a multi meter and check for shorts between wires.
