DIY power supply for HDDs Answered
I'm thinking of making my own external harddisk to keep on my desk. You know: for backups, etc.
I'm (probably) going to fit 2 HDDs in there. The HDDs need both 12V and 5V and since I don't want to connect two adapters to it I need to change the 12V that goes into the box to 5V. I've done some research and I think I got it figured out... I think a 78s05 condensator should do the trick.
Side note: the disks need 0.9A and 0.72A on 5V (=1.62A).
I've attached a picture where I show my idea.... any thoughts and most of all WOULD THIS WORK?
