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.
