Cute project, but does not sound very energy efficient to me.
- leoedin 15y agoI did pretty much exactly the same thing a few years ago. The power supply is about 25W, but judging by the heat coming off the frame I doubt it uses half that. The main power draw is probably the screen. I removed the hard drive and replaced it with a CF card (basically no power draw), and the fans have been replaced with a large heat sink. For my photo frame, I used cron and set various times for it to turn off the screen. Obviously it's a luxury in terms of power usage, but given that it pulls about as much power as a bright energy saving lightbulb, it's not really a huge issue. In terms of cost, 25W continuous costs about 6c a day, so I'd imagine the whole frame costs less than half that once you take into account the screen-off time and the reduced power draw anyway.
