Re: cheap UI for any project
Great idea... but (there is always but, with junk :)
You can't expect this thing to survive even half the lifetime of a decent home automation UI.
These things would run for far more time on batteries than this one. You will need to wire it to mains power and who knows if it's charging system is designed or even safe to run unattended all the time.
But, for prototyping it would be ok. Just like any of your existing hand held devices...
So about the only reason you would buy this is if it's your first handheld device, or.. you hate environment.
