So, this is a very low power and low cost device. I can't see why they
have constrained it by putting it into a plug-pack format? Why not
separate the power supply from the device (like the Zonbu or EeeBox
etc.) which would make it easier to incorporate into a car, a recumbent
bike or to power it from wind or solar via batteries etc. etc.? Seems
odd to me.
If it had some sort of wireless or powerline signalling system, then
I might see some point in packaging it like that. Maybe I am missing
something?
Cheers,
Bob Edwards.
