DIY tablet computer, maybe.

lol I shod put a pic on showing my work bench

Finally got something real done.
Not a straight edge in sight.
I'm going with steel and i've simplified the design a whole bunch since I want to actually get this finished. The steel is what I have on hand. I'm trying to stick to things I have now, like a keypad from an old mains powered calculator.
The idea is that the glass will be stuck to the steel - i'm gonna try that tape out. Then there's a plate behind the screen that screws into the front plate and holds the monitor in with some foam pads to act as springs so it's held flush against the glass but not with too much force. Then anything else will mount onto that rear plate.
The reason for the delay is that i've been caught trying to figure out how the font plate should look. Since once the glass is fixed to it I won't be able to drill any more holes in it I need to get that fully figured out.
Still thinking about how to join the sides of the box. I was thinking a few tack welds and hoping theres no serious distortions, but I figure i'd want the plate to still flex a bit to match the glass.
Oh yeah - does anyone know of any glass paint that sticks to glass really well? I want to mask the back of the glass off, the side that gets stuck down, with paint to hide the steel and tape behind it. Just searching for glass paint brings up arts and crafts type stuff.

So the glass plate will be on the outside of the tablet in front of the steel plate with the important hardware screwed on the back side of the plate with screws through it? You want to effectively black out the screws and the steel plate by painting over those areas on the glass?
If the paint's going to be on the back side of the glass you don't really need to worry about the paint getting worn or scratched so just about any rattle can of paint should work - as long as the glass is clean and dust-free. I think when they black out around the edges of automotive glass they etch the area they're going to paint to ensure a good bond for the paint. However I don't think this tablet will need to survive the exposure to the elements that automotive glass needs to survive.

The problem i've got is that the glass is also going to be a structural part to some degree, since it'll stop the display falling out forwards. And whatever paint I use will be between whatever adhesive I use to stick it to the steel. I guess it's still not going to be taking a whole load of pressure from the display so I could do some tests with the rattle cans i've got. I'm just assuming any old paint would practically fall off the glass.

But the solvent in the adhesive may well react with the paint and either wrinkle it or not bond at all. You need to experiment with samples.
