20 Android Tablets form an Interactive Photo Collage

20tabletFrame

You might not have a small army of unused tablets lying around, but if you did, you should try turning them into what Minn calls a “Giant Interactive Photo Array Display:” A Giant IPAD. Har har.

[Minn's] first step was to hit eBay, hoping to find a score of low-priced, broken-yet-easily-repairable tablets. The only ones available (and for cheap), however, were resistive touch screens with narrow viewing angles. After waiting patiently for nearly half a year, [Minn] hit the capacitive touch jackpot: snagging a pile of 10″ and 7″ Android tablets. The frame is custom made to provide a solid surface for mounting and enough depth for the tablets to fit correctly. Rather than form his own brackets to hold each device, [Minn] re-purposed some IKEA cupboard handles, screwing them into the MDF backboard and clamping the tablets to them with bolts that press against the case. An adhesive rubber bumper stuck to the top of the bolts prevents any damage.

Providing power to the diverse collection required another custom solution; two 5V 10A supplies and one 9V 16A supply fit into an accompany box safely deliver the needed juice. [Minn] chose an app that will grab photos from cloud storage so he can update the collection without having to dig around inside the frame. See the result in a video below! Want to try this project but only have one tablet to spare? The in-wall tablet mount might help.

Ideas based on photo frame clock

[Mahto] bought a digital picture frame but the image quality turned out to be terrible. He decided to turn it into a clock in a unique way. He loaded up 720 images, one for each minute in a twelve hour period. He then used an Arduino to simulate a button once a minute, cycling to the next image.

This is a simple solution and it works. Visions of hardcore hacks danced through our head when we first looked at this. We’re wondering if there is a way to inject image data into the frame’s memory? How about rewriting the SD card location where the image file that’s currently being displayed is stored, then having the frame reload the picture? Those are projects for a snowy weekend, but we’re sure that [Mahto] finished this hack long before we would have because he kept it simple.

Sooner or later we’re going to need a category for all of these clock hacks.
