How to power an old laptop screen with an old laptop battery ? Answered
I'm currently playing with Rasberry pis, and I just started a new project.
I found information showing how to re-use the screen of a dead laptop via a controler board you can find on eBay.
I'm planning to integrate all this in a suitcase to create a mobile retro gaming console. It should be easy to add a simple 220V plug to power all this.
But I was just thinking it could also be nice to be able to use this on battery as I also have many laptop batteries @home.
Rasberry power input is about 5V 3A
Audio amp input is from 1.8V to 12V
Screen controller board is 12V 4A
Here is what I want to do :
> When plugged : Add a circuit to charge the battery via a 220V input. That circuit should also convert the 220V to the power needed for the Pi, the audio amp and the screen.
> Unplugged : Add a circuit to convert the battery output to the power needed for the Pi, the audio amp and the screen.
I have no idea where and what to search for. Should I reuse the laptop power unit ? Any help would be highly appreciated.
