HI, All

Who tried to assemble and develop the industrial system based on a Android smartphone ?
Please, share your experience.

Say, if we need a black-box that contains an Android smartphone and some peripherals:

0) Android smartphone with OTG + AC-DC power supply adapter
1) USB OTG-adapter + needed cables
2) USB-hub + power adapter
3) coolers + power adapter (maybe independent with termo-sensor)
4) LED-lamps or torch + power adapter, for camera constant flash backlight
5) maybe USB controller of some power relays, for toggling some peripherals - say, cooler. Anyone used any such USB relay (2, 4, 8 channels) controller ? Any suggestion for models and USB-host debugging ?
6) AC power input for all the power adapters
7) Is any "watch-dog" reset for whole the system possible ?

Softwarely, i guess, Android app should control:

0) Internet connection, mainly the GSM\3-4G mobile one
1) remote control of the system: full output logging (and uploading the working result) and external income commands: what is better solution for Android (FTP, HTTP server)?
2) battery temperature control - temperature of the system can go out a top limit ...
3) camera, photos\QR-codes from it (if this is the main controlled parameter of the system)
4) ... what forgotten ?

Please, share your real experience and ideas
