Neat idea and a lot more ambitious that what I just setup. One of the vendors I've bought from in the past had a Thanksgiving 80% off deal on some 4-inch 320x480 touch screen displays. Price after the discount (not including shipping) was $8.99 each. So having three of model 3 Raspberry Pi boards, it seemed like a good idea to grab 3 of the displays even though I'd never seen one before. I got them in and tested them with no problems. I wanted a way to use at least one of them rather than just sitting in a box in the storage room as a lot of tech I've not had the time to test and implement ends up. So here's what I came up with to go on my nightstand:
I have a sensor in my bed that automatically arms HSM-Home so it's handy being able to see the status of that sensor. There's also a motion sensor limited to the floor area that acts as a secondary to disable HSM so I wasn't completely reliant on the bed contact before the RPi. The HSM status has been covered with a text tile that's 100% opaque so that I don't accidentally touch it and bring up the minuscule (unusable) menu. Since these are resistive touch, it's very difficult to hit the extremely tiny "X" to close the menu. Of course the bottom buttons are another way to activate and deactivate/cancel. I'm planning on trying to put together a nice (well... nicer than plastic) wood box to contain the RPi.
