Ask HN: need advice on H/W choice for prototyping system
Device: some sort of tablet. iPad and iOS are viable for high end consumers but to start off it is necessary to keep to a budget so bootstrapping the prototype phase is economically possible. So it seems Android is the way to go. I am open to assembling a device from parts e.g. cpu etc. board, LCD, etc.
Sensors: I suppose RFID is the way to go. The sensors would be located in spaces, e.g. a room. Individuals would carry corresponding bracelet, widget, whatever. Ideally the sensors should be battery powered so as to minimize the prototype infrastructure e.g. wiring, etc.
The goal of prototype is functional demonstration, so an initial plain (and possibly not so pretty) device is OK, but of course would be great if you can also recommend casing solutions.
I would appreciate any feedback and leads on resources such as vendors, etc.
Thank you, HN!
