Well I have connected the a simular cooling fan to the 3.3V Pin for the exact same reason and it works quite well so far. It’s been up and running for a couple of months now and I haven’t had a problem with it. So I reckon it should be ok ;)

RE: Old wine box + old monitor + RPi = MagicMirror
@madscientist I used a kind of acryl glass (plexiglass) from a company in Lucerne (Switzerland). Here is the link. It is approx. 1/4 of the price and weight compared to a real mirror. Still the reflection is pretty good, depending on the light conditions though (obviously). If you click on the link you’ll also find a review to this kind of 2 way mirror.

RE: Old wine box + old monitor + RPi = MagicMirror
@mnl Haha yeah I can understand that. My brother is studying in Huntsville and I was on exchange in Brisbane. The wine boxes were just sitting in the basement, so I used them, because we like italian wine ;)

Old wine box + old monitor + RPi = MagicMirror
Six months ago I came across this forum and I knew I wanted to build a MagicMirror. So I built one and I changed and added bits and pieces along the way. There are still some things I’d like to change, but I haven’t had time to do so. This is the result so far below:
I used old wine boxes to create a frame for the mirror, miraculously the monitor and the wine box had the excact same height, which made it perfect for a frame.
I wanted to be able to change the pages whenever I wanted, so I attached an old Makey Makey (which I received as a present many years ago) and I connected the keys to the screws at the bottom side of the frame. So by touching two screws at the same time, the page changes and you can’t see any buttons or simular things. You have to touch two, because one is the ground key and the other the actual key. Basically you have to short-circuit the two screws with your fingers, that’s just the way a Makey Makey works.
Here are some photos:

Page 3: more or less a picture frame with some information
The wine box, with the red power cord. (if you can’t hide the power cord, make it as obvious as possible and sell it as a feature and not a bug ;) )
And the screws to change pages, if needed. The RPi changes between the three pages automatically every 20min anyway:

RE: DropboxWallpaper pictures are rotated to the left
@sean Yeah I see. No worries though, I still really like the module. Cheers

RE: DropboxWallpaper pictures are rotated to the left
@sean Thank you very much, all seems to work, and the orientation of the pictures appears to be correct. There is only one small issue. Sometimes the mirror only shows a very small part of the pictures (approx. a fourth or so). Not always, but sometimes. I have got no idea what might cause that, because all the pictures were taken with the same smartphone.

RE: DropboxWallpaper pictures are rotated to the left
@sean Thank you very much. I’ll try that tomorrow and I will consider the README file.

RE: DropboxWallpaper pictures are rotated to the left
@sean Some pictures were indeed taken with an older camera (approx. 6 years old) but some were taken with a recent smartphone. I encountered the problem with all of them. The dimensions of the pictures seem to change correctly, when they are manually rotated. But anyway thanks for your help. I might just try and safe some of the pictures in landscape mode with two black bars on the side so that the pictures will be shown the right way up and appear to be in landscape mode for the magicmirror.

RE: DropboxWallpaper pictures are rotated to the left
@sean Thank you for your quick reply. I have checked ‘contain’ and ‘hybrid’ mode and all the pictures remain rotated to the side… Your help would be much appreciated.

DropboxWallpaper pictures are rotated to the left
Hi Everyone
I’ve got a problem with MMM-DropboxWallpaper when displaying protrait pictures in the ‘cover’ mode. Landscape pictures are displayed correctly, but the portrait pictures are rotated to the left. On dropbox they are correctly saved (upright). Anyone any idea why this happens? I have tried to rotate all the portrait pictures to the right, but on the mirror they are still rotated to the left.
Many thanks in advance.
