How can i make a dc power filter?

ive got a wall wart spitting out 10.5v dc, and i need to clean it up, as it is going to a psone screen.

What are the power input specifications of the screen? What are the output specifications of the power supply? Is the plug not already regulated? However, to get from mains to nice DC, you need to: Transform - Transformer Rectify - Diode(s) / Bridge Rectifier Smooth - Capacitor Regulate - Regulator

What do you want - smoothed, regulated voltage? L
