Inexpensive Samsung Galaxy Tab 3 Lite, 7" android tablet. $80 refurb unit, going to be dedicated for vehicle use and wanted to start off cheap anyway.
Been wanting to do something like it for a while, then had some ideas sparked by member cyclic's topic a couple weeks ago.

I just got the tablet this morning, and while it was fully charging and then downloading and installing a list of useful apps I had already put together, I got busy fabricating the mount. I started off with making a pattern buck of the the tablet, out of some scrap MDF. Bandsaw, table-mounted 12" disc sander, foam sanding block and some 120grit paper. I even tried the model the bevel on the rear of the tablet.
Next it was transferring my cardboard pattern to some textured 1/8" polystyrene(?), commonly used for custom switch panels and the like. More band saw, table disc sander and some dremel wand action for the smaller inner radii on the tabs that will grab the tablet.
Then it was on to the heating and the bending. I've done this sort of thing long ago, using the kitchen oven on 'warm'. There's a narrow temp band between 'low as the oven will go' and 'plastic ruined / too soft', so I kept opening to door too frequently trying to check things. Couldn't remember the old rule of thumb and didn't bother looking it up. So I wound up breaking out my cheap Harbor Freight 1500watt heat gun. Like licking a Tootsie Pop to get to the gooey center. 1,2,3,,,,,35, close enough
I used an 18" metal bending break, worked fine on the plastic.
I ran into some fiddly hassle when I was bending the side tabs, my buck was too thin. I'd done it that way on purpose, so the tabs when fitted to the buck would really hold the real tablet snugly. Turned out WAY too snug. So I had to keep shimming the ends of the buck with masking tape and re-heating and clamping, four or five times over to get a fit I'd accept.
I used just a bit of 3M super double-stick tape, the gray stuff with the red backing. I'm not done working inside my dash yet, so I didn't want to go overboard sticking it down. I put a double thickness on the right edge of the mount, as the dash falls off in that direction and I wanted the tablet square with the radio face. And here it is in place. I also worked some of the rough edges or the mount tabs after things were fitted, for appearances. And worked those tabs over with a sanding sponge to dull them down.
I still wanted the tablet snug, so when I got the fitment close I called it done. It's a little too tight in the right side, but that works ok. It's easier to lift it up by the top left edge and sort of rotate it out. But it is still snug enough that I believe it will handle the rough desert / forestry roads in my region without popping up and out. And lastly a shot of the bracket alone. It's plain enough it shouldn't invite a break-in. I can just leave the tablet in the vehicle console when not using the vehicle.
I have a double USB / power port converter and a suction cup mount high center on the windshield for my iPhone. I'm planning a few more changes, adding some more USB power locs both on the high console and dash, so I can keep the power cable tangle to a minimum.
I've already put BackCountry Navigator, US Topo Maps Free, Offline Maps & Navigation, and a bunch of HAM radio related apps on the tablet, with a lot more to come. Already took a spin around the neighborhood with US Topo maps Free running with the Tablet's built-in GPS, got about 50' accuracy with it, was cool to see the map moving. Really looking forward to doing a lot of neat stuff with this setup.
eta I'm also soon doing a dash upgrade / swap, the bezel and internal stereo chassis of an 03-06 Sierra/Yukon/Tahoe/Sub, into my '02, which will provide for an easy install of a double-din entertainment unit, DVD, hand's free ph, USB / bluetooth connectivty, the whole roster of goodies. Together they'll look a lot like this -
And with the CB and 2m Ham in my homebuilt center console, a dashcam up behind the rearview, and the windshield-mounted iPhone. Gonna be a busy but streamlined 'cockpit'.
