I think you're overthinking this. These are cheap, effectively disposable tablets. Why not just glue something to them? Take an electrical junction box cover. Use a dremel tool to cut four slots in it, spaced so you can thread two worm clamp type hose clamps through them. Bend the centers of the pairs of slots up a bit to give a space so the strap of the hose clamp fits and the rest of the plate sits flat against the tablet. Thread the hose clamps through. Epoxy the junction box cover to the back of the tablet. Now you have a tablet with a pair of worm clamps attached to it, that you can loop around and tighten on to the pole. You can use all manner of adhesives to attach such a homemade mounting plate to the back of the tablet - epoxy, construction adhesive, double sided tape, etc. Just think of those anti-theft plates that you find glued to old computers to allow cable locks to be installed. Those stay stuck. You're just creating one of those with hose clamps threaded through it, so you can mount it to a pole. Maybe not the most elegant, but they'd cost less than five bucks apiece to make, and nobody would ever see them because they'd be behind the tablets. -Ian On Mon, Feb 6, 2017 at 6:48 PM, Evan Koblentz via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Sooo.... there are all kind of good ways to attach solid pieces to the poles, but we still need something specific for the tablets themselves.
The outside of these tablets is 8.8 x 5.8 x 0.4.
If we could find (or if someone can make/machine/3-D print) rectangular cases that have a cut-out in front for the screens (7" x 4.5", starting 13/16ths from the top edge of the device)....
