I have been considering doing a PCB layout for providing regulated power for displays (and possibly low-power computers). Powering the LCD frontend of a car PC system is always the biggest hassle of getting the system up and running. I've looked around and it seems to me that regulated DC supplies for automotive are WAY overpriced and WAY too big.

I know a lot of people are running touchscreen head units. I'm curious how many are running PC-driven ICE systems... or for that matter, any setup that requires strictly regulated DC voltages. I have always just soldered power and gound lines onto the outputs on my automotive PC power supply. This is not ideal for me. I would classify it as "ghetto rigging", for lack of a better term.

I'd like to see some comments/suggestions/thoughts regarding this kind of a design. Is there any interest for something like this?
