I am building a digital photo viewer with an old lcd screen (from a playstation 1) and a sandisk photo viewer. I would like use one power adapter for the whole thing but each item has its own power specs.

Sandisk - 12vdc, 600ma

LCD Screen - 7.5V dc, 2.0a

What would I need to buy and build?

Here's the instructions for the project
