The DIY Cheap n Easy Photo Frame. OK, so we’ll go with the cheap, but easy? Mmm…
Now, the screen can only take 7.5 volts of power. Much more than that, and it’ll fry. The adapter that comes with the viewer is labeled for 12 volts (but I was measuring 15 with my multimeter… all lies!) and so you’d think that the viewer needs 12 volts to run. Not so! I just so happened to test if it would run off of 7.5 volts, and luckily it does. This means that you only need one adapter to power the whole project, and you don’t need a voltage regulator or whatever to step down the power for the screen.
