Backup and storage in a Mobile home.
Looking to get backups and storage for MP4 video file backup of all the DVD's. Play them on the TV and backup the laptop's. Also Partitioned for photo storage.
The Time Capsule fitted with a 3TB drive and an Apple TV box both need 240v to run.The problem is you need 12V and 5V both +-10% and 3.3V for the Apple TV box.
The van power is 14V down to 10V.
So I built a dual PSU using two 9A DC-DC buck convertors. To give 12V and 5V and a small 3A set to 3.3V. mounted in a black box in the locker.
