Hi Andrey,

Thank you for your answer.Actually, NHW is very low-power so I think it
could be geared toward any hardware.But actually I don't have hardware
skills, so NHW is not a real hardware project for now maybe? I agree with
you that it is extremely difficult (for me) to build a community around
NHW, I'm certainly very bad/underskilled at it.Any help is welcome!

Cheers,
Raphael
